How to properly tune and strengthen the suspension of VAZ cars. How to properly tune and strengthen the suspension of VAZ cars What is included in the suspension of a VAZ 2107

Do not think that only tuning lovers are engaged in the installation of additional elements of the car's structure.

Many car owners often do this in order to give domestic car, for example, a VAZ car, better driving characteristics.

Today we will talk about the main types of modifications to the suspension of VAZ 2107, 2109, 2110, 2106, 2112, 2101,2105, produced by drivers, and also evaluate the feasibility of their installation.

Here are the basic principles of the correct approach to tuning the suspension of VAZ cars and other domestic cars, as well as ways to strengthen it.

And although the procedure for installing individual additional suspension parts for many VAZ cars is the same, you still need to understand that their installation on VAZ 2101 and 2112 will be different.

The most popular element, widely used by many owners of Russian cars, is the front cross-brace.

Its installation is carried out in the area of ​​the upper supports of the shock absorbers, by fixing the struts between the glasses.

The main purpose of this part is to increase the angular rigidity of the body and improve the quality of vehicle handling.

In addition, the presence of the spacer helps to eliminate the "floating" of the geometry of the suspension arms, resulting from hard blows pits or bumps in the road.

The main reason why many motorists, in particular the owners of VAZ cars, make such modifications, is the insufficient rigidity of the body, which contributes to the deterioration of controllability, the appearance of a feeling of a "sluggish" steering wheel and the manifestation of excessive rolls that arise when performing maneuvers.

This is found exclusively when driving at high speeds, mainly associated with trips on suburban roads.

Those drivers who spend most of their time within the city and are accustomed to calm, unhurried driving may not even notice these shortcomings.

The spacer is a fairly thick metal rod, either of a fixed length intended for specific car models, or endowed with the possibility of spatial adjustment, which facilitates the installation of the element on different cars.

Its installation is carried out when the machine is placed on a flat surface by screwing several nuts onto the upper studs of the shock absorber supports.

If, for some reason, there is a mismatch of the mounting holes, the car body must be slightly "pulled" in the right direction.

Installing the cross bar makes some sense. You will not only significantly increase the car's handling, but also extend the "life" of its body, thanks to the improved torsional resistance.

Auxiliary support of the power unit

The purpose of supplementing the standard engine mounts with another auxiliary module is to minimize the amplitude vibrations of the engine during sudden braking, acceleration and overcoming road hills or holes.

Its presence excludes the so-called "pecking" - inertial phenomena occurring during the operation of the car.

The presence of the auxiliary support also prevents spontaneous disengagement of the transmission gears.

This greatly reduces the risk of unpleasant incidents that directly affect safety.

It is usually difficult to install this component yourself.

A certain skill is required, which an ordinary motorist does not always have.

Separately, we will say that some engine models imply the installation of the fourth support only after transferring the ignition unit.

This, on the one hand, is an additional difficulty, but, on the other hand, it significantly improves the operating conditions of the electronic module, moving it away from the road, thereby reducing the amount of dirt that gets on it.

Additional support power unit often installed during tuning the suspension of VAZ 2109, 2110 cars.

Rear beam stabilizer bar

The element considers as its purpose the reduction of the side rolls of the machine, the improvement of the interaction of the wheels with the roadway when cornering, as well as the distribution of the load between rear shock absorbers when driving over bumps with one of the wheels.

The fact is that when hitting deep potholes, an extremely strong hanging occurs, often causing the rear shock absorber rod to be pulled out.

When working in compression, the shock absorber, on the contrary, is unnecessarily prone to breakdown, which seriously affects its durability.

When amplified, this does not happen. The resulting force is distributed between both wheels with an approximate ratio of 3 to 2, which has a positive effect on the quality of control and reliability of the suspension elements.

The stabilizer bar is installed directly on the rear beam of front-wheel drive models. domestic cars VAZ and others.

Installing a beam reinforcement should not cause any problems for most drivers. To do this, you need to use a flyover or a viewing pit, after which, according to the instructions, fix the bar to the beam.

The only difficulty that can arise is the need to drill eight holes in the girder body.

The front stabilizer with increased stiffness is a tool designed to significantly improve the quality of vehicle handling.

Its main difference from the standard part is in harder rubber bushings located at the fixing points.

The suspension is necessary for a VAZ 2107 car so that movement on it is not only safe, but also comfortable. The suspension device is usually presented to a novice car enthusiast as very complex scheme, but let's take a closer look at it.

What is the suspension arrangement?

The suspension on the VAZ 2107 is represented by a set of assemblies from various parts and rotating mechanisms.

The main elements among them should be called:

• elastic parts, the work of which we can feel when driving on uneven terrain;
• guide parts responsible for the trajectory of the wheels;
• shock absorbing parts or simply shock absorbers. They help to reduce excessive vibrations of the car body resulting from the action of the road surface.

Suspension functions

The unique suspension device on the VAZ 2107 plays an important role in the design of the car:

• it connects the body itself and the wheels to each other;
• provides the highest possible smooth running even under the worst road conditions;
• "Informs" the driver about the quality of the road by transferring the emerging force to the bearing system.

Suspension and its structure

The front suspension mechanism of the VAZ 2107 car is called "independent". It has a double wishbone and a cylindrical spring, shock absorber parts with a telescopic structure, and a stabilizer with a special function. lateral stability.

The base with the lower arms is screwed to the cross member connecting to the front side member. There are washers along with special spacers next to the cross member and the lower base. It is they who help determine the angle of the axle when turning the rear wheels.

The upper arms are bolted together. Its levers rotate, as they have a hinge device. The levers have a steering knuckle (there is a brake disc on it) along with a wheel hub.

Front suspension springs are cylindrical. Their upper edge touches the mudguard strut, and the lower edge abuts against the support bowl from the lever (lower). All this will be clearly shown by the diagram.

The springs themselves contain shock-absorbing elements. They are connected to the body of the VAZ 2107 using rubber pads. They have a connection with the lug of the case thanks to the lower lever.

A steel spring anti-roll bar serves to prevent the vehicle from skidding. Its attachment at the front is carried out through rubber pads applied to the front side members, and at the rear using the lower suspension arms.

The suspension diagram for the VAZ 2107 is presented below.

VAZ 2107 in the original looks rather modest. The same modest are also dynamic characteristics car. Therefore, many car owners modify and improve almost all components and systems of the car: changes appearance, the interior becomes more comfortable, the engine power increases, etc.

Radical tuning of the VAZ 2107

You can use tuning to transform a serial sedan that rolled off the assembly line at the beginning of the 21st century into a car that vaguely resembles the original. Examples of professional tuning can be seen at various international competitions, for participation in which cars are specially altered and modified.

Tuning concept

The term tuning literally translates from English as tuning or adjustment. Any car can be tuned to such an extent that it becomes unrecognizable. Each owner modifies his VAZ 2107 in his own way, determining individually which components and parts need modification.

Before starting tuning both the car as a whole, and any component part, it is important to understand a number of simple requirements. The modernization of the machine must not contradict the Russian legislation and regulations. road traffic(SDA). First of all, this concerns external tuning of the body, replacement of wheels and disks, external and internal lighting. Everything that is attached to the sides and front of the machine must not: have parts protruding beyond the dimensions, be poorly welded or screwed on, contradict the requirements of UN Regulation No. 26.

There are three types of tuning.

1. Technical tuning: improving engine performance, revision of the gearbox, transmission, chassis. Sometimes this problem is solved radically - standard units and mechanisms are changed to units and mechanisms from other car brands.
2. Internal tuning: making changes to the interior of the cabin. The design of the front panel, seats, ceiling is changing, which are sheathed with fashionable materials, inserts are made of metal, expensive wood species, etc.
3. External tuning: body refinement. Airbrushing is applied to the body, body kits are installed, the configuration of thresholds, wheel arches, etc. changes.

An example of tuning a VAZ 2107

The appearance of the VAZ 2107, shown in the figure, has changed a lot due to an unusual homemade front bumper, lathing, front fenders and sills painted green.

The ground clearance decreased from the factory 17 cm to 8-10 cm, which made the car look like a racing sports car and had a positive effect on stability and handling. The paint made the car visible in traffic. Thus, external tuning made the ride safer and gave the VAZ 2107 a memorable appearance.

Body tuning VAZ 2107

VAZ 2107 is ideal for external tuning for the following reasons.

1. The car initially has a discreet appearance.
2. On sale there is a wide selection of parts, accessories, tuning accessories at affordable prices.
3. The car does not have sophisticated electronics, automation, self-diagnosis systems that could be damaged during work.

Most often, external tuning is limited to window tinting and the installation of stylish rims. To give the body of the VAZ 2107 a streamlined shape is an almost impossible task. However, for speed characteristics the car does not need it. It is possible to reduce the force of air currents under the bottom by installing low-lowered spoilers, which harmoniously integrate with the body frame in the places where the sills and bumpers are installed.

You can give the car body a sporty look by:

Body kits and bumpers are made independently. It is very important to cut and bend them correctly. For this, you can use special computer programs.

Windshield tinting

In accordance with traffic rules toning windshield it is recommended to do it only at the top with a strip width of no more than 14 cm. This will protect the driver's eyes from the sun's rays. For tinting you will need:

• tint film 3 m long and 0.5 m wide;
• glass detergent or shampoo;
• rubber scraper to remove water;
• nonwoven napkins;
• marker;
• a sharp thin knife (clerical can be used);
• roulette;
• spray bottle.

The tinting process itself is carried out as follows.

1. The windshield is removed from the body and released from the sealing rubber.
2. The glass is transferred to a bright, clean corner of the room, where there is no dust.
3. The glass on both sides is thoroughly washed with soapy water. Stubborn dirt can be removed with a solvent.
4. The tint film is applied to the outside of the glass and outlined with a marker with a tolerance of 5–7 mm.
5. The film is cut along the line with a sharp knife.
6. The protective layer is removed from the film.
7. The surfaces of the glass and the adhesive side of the film are moistened with soapy water.
8. The film is applied to a clean, damp surface. In this case, the formation of horizontal folds should be avoided.
9. The film is gently pressed with a plastic or rubber scraper from the center of the strip to the edges. Wrinkles are smoothed out at the same time. At the same time, it is advisable to warm up the film with a construction hairdryer. There should be no bubbles between the film and the glass. If they appear, they should be driven out with a scraper to the side that has not yet been glued, or pierced with a thin needle.
10. The glass is dried for several hours and installed on the car.

Headlight tuning

The easiest and most affordable way to tune headlights and rear lights VAZ 2107 is a replacement of standard bulbs with LED ones.

To do this, they usually use a special tape with spotlights glued to it. Thus, you can make original running lights, angel eyes, etc. You can also purchase pre-tuned front and fog lights and taillights from car dealerships.

Rear window tinting and decorative grille installation

If the car owner does not have experience in tinting, it is advisable to purchase the cheapest film for darkening. For rear window there are no restrictions on light transmission. Tinting is carried out without dismantling the glass, since it is glued to the sealing rubber. The work will require the same materials and tools as for the windshield. The film is glued from the inside in the following order.

1. The glass is washed with soapy water, and stubborn dirt is removed with a solvent.
2. The tint film is applied to the outer damp side of the glass.
3. The tinting is given the shape of the glass. To do this, the film is pressed against the glass and smoothed out under a stream of warm air from a building hair dryer. In order not to overheat the tint, the air temperature should not be too high. The hair dryer moves along the entire surface of the film, stopping in each place for 2-3 seconds.
4. The protective layer is removed from the tint film, and it is glued from the interior to the damp inner side of the glass. Since the film has taken the form of glass, it should fit snugly enough. Water from the tinting is expelled using a scraper.

Sometimes, instead of tinting, a decorative grille made of two-millimeter plastic is installed on the rear window, which can be purchased at a car dealership. For ease of installation, it consists of two halves and is easily attached to the rear window rubber seal from the outside. The grille can be painted to match the color of the car or left as is.

Installation of roll cage

The installation of a safety cage will help to protect the driver and passengers of the VAZ 2107 in extreme situations. The installation work of the frame is rather complicated. In order not to violate the geometry of the body, careful observance of the dimensions, welding and fitting of pipes in the cabin using a hand-held power tool will be required.

Tuning of the salon VAZ 2107

In the original it looks very modest. The lack of frills provides the car owner with ample opportunities for tuning. Before radical interior tuning, the seats are removed from the cabin, the doors are dismantled and disassembled, the steering wheel, the dashboard and rear panels, as well as the floor and ceiling trim are removed.

Soundproofing of the salon VAZ 2107

Internal tuning should begin with the installation of new noise insulation, without which it makes no sense to install a high-quality audio system. During the installation process, preliminary preparation is made for tuning all elements of the cabin. Depending on the readiness of the body surfaces, the insulation can be installed either in parts or completely. First, the outer wheel arches and the bottom of the car are processed, then the trunk, the hood, the floor and ceiling of the cabin, the doors and the dashboard. After dismantling the engine, the bulkhead in the engine compartment is insulated.

Required tools and materials

For noise insulation you will need:

• set of open-end wrenches;
• set of spanner keys;
• a set of sockets with an extension and a ratchet;
• construction hair dryer;
• a set of screwdrivers with different blade shapes;
• vibration-insulating material on a mastic basis ("Vibroplast Gold" or "Silver") with a thickness of 4 or 8 mm;
• Shumka (products of the enterprises "Shumoff" and "StandartPlast").

Soundproofing the floor

The soundproofing of the floor is carried out as follows:

1. The fasteners are unscrewed and the front and rear seats are removed.
2. The factory covering is removed from the floor.
3. The floor is degreased and treated with special mastic.
4. The floor is covered with soundproofing material.

Experts advise to lay thin Shumka in several layers without gaps and gaps. Sound insulation is more effective than laying thick material in one layer.

Front panel tuning

There are a lot of opportunities for tuning the front panel of the VAZ 2107. You can cover it with expensive material, make inserts of aluminum, chrome or precious woods. For appliances, you can make LED backlight or install the GF 608 Gamma panel with on-board computer... The steering wheel can be replaced with an analogue from a foreign car, covered with leather or other material.

Obviously before tuning dashboard need to be dismantled.

Replacing the interior trim and seats

You can effectively change the look of the cabin by replacing the upholstery of the seats, headlining, front and rear panels, doors with more modern and practical materials. At the same time, it is not recommended to use fleecy materials (phlox, carpet, etc.). When cleaning such surfaces with a vacuum cleaner, their surface will quickly lose its original appearance. For self replacement upholstery of the seats will require a sewing machine and the ability to handle it.

On sale there are special inexpensive kits for tuning the VAZ 2107 interior, consisting of plastic decorative overlays for the dashboard, sun visors, armrests, door cards, acoustic grilles, etc. Such a set can be matched to the color of the car and choose different versions.

Seat upholstery

The ideal option is to install more modern seats in the VAZ 2107 salon. Chairs from Toyota corolla produced in 1993-1998, the fastenings of which coincide with the standard seat bolts of the VAZ 2107. However, it is quite expensive.

To tighten the seats you will need:

• material (fabric or leather) for upholstery;
• foam rubber;
• glue "Moment" or similar;
• electrical tape or tape;
• sewing machine;
• thick needle;
• threads of a suitable color;
• sharp knife;
• awl;
• set of wrenches;
• hammer;
• screwdriwer set.

The work is carried out in the following order:

1. The front seat is removed from the rails and placed on a flat surface.
2. The old paneling is unstitched at the seams. In doing so, it is necessary to prevent damage to the edging.
3. The places where the casing is glued to the cardboard inserts are wetted with gasoline.
4. The old upholstery is neatly pulled off the backrest and seat cushion.
5. A pattern is made from a new material along the contour of the old sheathing with scissors.
6. On sewing machine double stitching is used to sew up the details of the upholstery and edging. Depending on the material, the joints can be manually stitched, glued or heat welded.
7. Foam rubber and sagging seat springs are changing.
8. On the back and pillow front seat the new casing is carefully stretched.

The rear seat is pulled in the same way.

Replacing door cards

The installation of new door cards will also noticeably refresh the interior of the VAZ 2107. This is quite simple to do. As new cards, you can use plastic wood-like pads. Alternatively, you can buy a set of various inserts for the VAZ 2107 interior in the store.

Headliner trim

Some car owners attach hardboard to the ceiling of the VAZ 2107 cabin and already glue the carpet onto it. It is quite time consuming and laborious, but the result is very effective. Before starting work, the windshield and rear windows are dismantled.

Sometimes the standard upholstery is changed to leather or some other material. However, before that, you should strengthen the soundproofing of the ceiling. For this:

• the factory Shumka is carefully removed;
• the metal surface of the ceiling is degreased;
• a vibration damper is glued to the degreased surface (experts recommend using a construction hair dryer);
• a splan layer is glued to the vibration damper;
• the surface is covered with factory shumkoy.

Other possibilities of internal tuning VAZ 2107

The tuning of the VAZ 2107 salon can be supplemented with:

• replacement or modification of sun visors and rear-view mirrors;
• changing the interior lighting with the installation of footlights;
• installation of a new radio and acoustic system;
• installation of electric windows;
• replacement of regular rugs with decorative;
• modernization of other parts, devices and devices.

VAZ 2107 engine tuning

The manufacturer installed on the VAZ 2107:

• carburetor engines with a volume of 1.2 and 1.3 liters;
• injection engines with a volume of 1.5 and 1.6 liters.

The most common types of powertrain tuning are:

• an increase in the working volume of the combustion chambers;
• replacement of the camshaft;
• installation air filter zero resistance;
• remodel exhaust system on a straight-through muffler.

The greatest effect is obtained by installing a turbo kit on the engine.

Ways to increase engine power VAZ 2107

You can increase the power of the VAZ 2107 engine in the following ways.

1. Cylinder head tuning. Due to this, the power can be increased by 15–20 liters. with. Since the head is made of cast iron, all the operations for its completion are quite elephantine and time consuming.
2. Carburetor tuning. The diameters of air and fuel jets are changed, enlarged diffusers are installed.
3. Installation of two or four carburetors.
4. Installation of a turbocharger consisting of a compressor and a turbine.
5. Boring cylinders to increase their diameter.
6. Installing forged lightweight pistons instead of cast ones.
7. Replacing the standard air filter with a zero resistance filter.

On VAZ 2107 injection models, it is recommended to carry out software chip tuning. This will not only optimize the performance of the engine, but also normalize the operation of the electronic control unit. The effect will be maximum if chip tuning is performed on a serviceable engine that has passed a full technical inspection.

Tuning of the exhaust system VAZ 2107

Some car owners make the engine sound louder to sound like the growl of a sports car. For this, the catalyst is replaced with a special flame arrester. Other owners of the VAZ 2107 believe that tuning the exhaust system is justified if the result is an increase in engine power. When assessing the feasibility of such measures, it should be borne in mind that improper installation will lead to an increase in fuel consumption and a deterioration performance characteristics car. Therefore, the work on tuning the exhaust system should be entrusted to professionals.

When tuning the exhaust system, do not forget that the maximum engine sound level should not be louder than 96 dB. Alteration of the exhaust gas evacuation devices cannot impair the environmental class of the engine.

Tuning of the exhaust manifold and the intake pipe

For better purging of exhaust gases, extreme sportsmen change the standard exhaust manifold for a StinGer spider complete with a double intake pipe (pants) made of stainless steel. This allows for an increase in power at high revs by about 9 hp. with. In this case, the formula for the exit of exhaust gases "4-2-1" does not change.

Since the inner walls of the StinGer are smoother, installing such a manifold will increase the exhaust efficiency and increase the power at maximum rpm by 9 hp. with

The flat surfaces of the StinGer manifold flanges ensure that they fit snugly against the cylinder head and pants. However, the new receiving tube lacks seat with thread for oxygen sensor. Therefore, if necessary, a nut is welded on this pipe in front of the catalyst, into which the sensor is installed.

Since the pants end with a flange, the resonator of the injection model is attached without problems. However, on carburetor VAZ 2107, this unit is made differently, therefore, it is better to immediately install a resonator from an injection engine on such a car.

Installing a straight-through muffler

A standard VAZ 2107 muffler consists of two pipes welded at different angles and lined with a non-combustible mineral wool filler, which reduces the speed of exhaust gases and softens the exhaust. To increase the volume of the exhaust and make the exhaust flow straight, the exhaust system is audiotuned. Instead of a conventional muffler, a direct-flow, do-it-yourself muffler is installed.

In a straight-through muffler, the exhaust gases do not make turns, which slow down the speed, and are additional resistance that reduces engine power

Thus, with the help of tuning, you can turn the VAZ 2107 into a completely new car... In accordance with the wishes of the car owner, almost any units and parts, including the engine, are being finalized. Tuning items are commercially available, and it is quite easy to do most of the work, carefully following the instructions of the professionals.

"Seven" - the last rear-wheel drive car in lineup WHA. The front suspension of the VAZ 2107 has fewer parts than the “older” front-wheel drive models, so its repair is easier.

Front suspension device VAZ 2107

"Seven" is equipped with independent suspension consisting of an upper and lower arm, a spring and a shock absorber on each side. The lower arms are interconnected via the anti-roll bar.

The axles of the lower arms are rigidly attached to the cross member (beam), which is attached to the front side members of the body. The role of the axes of the upper levers is performed by the mounting bolts with which the levers are screwed to the mudguard struts.

The mobility of the levers is provided by rubber-metal hinges - silent blocks.

The wheel hub is bolted to the steering knuckle, which is held at the ends of the levers by ball bearings (top and bottom). This ensures that the wheels turn around the vertical axis.

The front suspension springs are located between the lower arms and the mudguard, which smooth out bumps when driving on uneven sections of the road. So that the springs do not move during the ride, their edges are inserted into the support cups.

The shock absorbers, which absorb vibration energy, are attached by the body to the lower arm, and their rods are screwed to the mudguards through rubber cushions.

The anti-roll bar is connected to the arms and side members via rubber bushings to eliminate direct metal contact and absorb shock loads.

VAZ 2107 front suspension malfunctions

Repair or replacement of the VAZ 2107 front suspension is required in case of wear or breakdown of its parts. The most susceptible to wear are rubber and rubber-metal bushings, shock absorbers and ball joints. Breakage of the latter is the most dangerous, since the steering knuckle in such cases turns out together with the wheel, and the car loses control.

To determine breakdowns, it is necessary to inspect and diagnose the condition of the front suspension.

The inspection consists in checking the absence of oil leaks from the shock absorbers, the condition of the rubber parts of the parts and the integrity of the spring.

Checking the front suspension parts of the VAZ 2107

It is easy to check the condition of the shock absorbers: press down hard on the wing, forcing the spring and shock absorber to compress and release. The machine should return to its original state and not continue to swing.

The condition of the ball joints can be assessed by checking the backlash of the parts with a loaded and unloaded suspension.

All rubber parts (anthers, bushings, bushings) must be replaced at the first sign of wear or damage. Silent blocks must also be replaced if there is a lever play on the axle.

Replacement of ball joints VAZ 2107

To replace the ball, it is necessary to jack up and remove the wheel. Then unscrew the nut holding the steering knuckle support pin and press out the last one.

After that, you can unscrew the support from the lever and remove it together with the boot. It remains to install a new ball joint with a new boot and assemble by performing the previous operations in reverse order.

After replacing the ball, it is advisable to adjust the angles of the front wheels (wheel alignment).

Replacement of silent blocks VAZ 2107

Repairing the front suspension of the VAZ 2107 often requires replacing the silent blocks. To carry out this operation, the upper arm must be removed. The bushing of the lower arm can be changed without removing the arm from the vehicle.

The silent blocks are pressed out of the lever and pressed into it using a special puller. To remove the upper arm, it is necessary to press out the support pin.

The bushing of the lower arms can be replaced by unscrewing the nuts on the arm shaft. Removing the lower levers is only worth replacing with new ones. But such an operation is usually required only when eliminating the consequences of an accident.

Replacing the front shock absorbers VAZ 2107

The front shock absorbers of the VAZ 2107 cannot be repaired, therefore, in case of poor performance or the presence of oil drips, they are changed to new ones. To replace them, it is enough to unscrew the two fastening nuts on the lower arm and the nut that secures the shock absorber rod in the mudguard cup. The shock absorbers are removed and inserted through the hole in the lower arm. To get or insert the shock absorber, it must be squeezed.

Replacing the front springs VAZ 2107

Replacing the front suspension springs is done after removing the shock absorbers and undocking the anti-roll bar (the latter interferes with the free movement of the levers). Also, to replace the spring, loosen the nuts securing the axis of the lower arm.

To lower the lower arm as much as possible and release the spring, it is necessary to press the pin of the lower ball joint from the steering knuckle.

Before installation, a new spring must be compressed and fixed with special ties.

The assembly of the assembly is carried out in the reverse order. Spring ties can be removed only after attaching the ball pin in the steering knuckle.

For more information on replacing springs, you can read

Repair of the VAZ 2107 suspension is not particularly difficult and does not require special knowledge and special qualifications. The only question is whether there is a special tool (pullers and ties) and a viewing hole in the garage.

Here is a video of the complete disassembly and correct sequence of the front suspension.

Everyone will be happy to ride in a car seat. With the breeze, on padded seat... No shaking or bouncing. Stop. And what ensures such a smooth running of the machine? This is the job of the car suspension. Even VAZs have several types of them that are worth considering.

Front suspension VAZ 2107

On any car brand, the front wheel suspension is more complex than the rear damping system. This is due to the fact that the front wheels are steering, and unlike the strictly directed rear wheels, they have freedom of directional movement. In general, the front suspension running VAZ 2107 is pretty powerful. It is designed in such a way for the possibility of driving on roads that do not have an asphalt surface. After all, this car is the latest version of the so-called classic VAZ series. It is the cheapest in the price range, and therefore the most popular among rural residents.

Front suspension device vaz 2107

Conventionally, the VAZ 2107 suspension can be divided into 4 nodes. Two triangular levers. The bases, both levers, are attached to the car body on movable mounts. Between the protruding tops of the "triangles-levers", a pivot lever connected to the steering is fixed by finger joints. Between the lower arm and the side member, a spring with a shock absorber inside passes through the opening of the upper arm.

To synchronize the suspension of the right and left sides, a lateral stability bar is installed between them, which, however, has decent freedom of position. It is attached to the lower arms. Basically, this is all a modification of the VAZ 2101 front suspension, then VAZ 2103, 2106. Preventive maintenance of the VAZ 2107 front suspension usually consists in replacing ball joints and rubber bushings.

Rear suspension VAZ 2107

The rear suspension of "classic" VAZ cars is directly connected to the rest of the chassis. In the rear suspension of the VAZ-2107, the leading rear axle is inscribed, which through cardan transmission and the rest of the transmission is connected to the car's engine. The wheels are oriented strictly in the direction of the vehicle. These conditions determined the features of the rear suspension of the VAZ-2107. Like the front suspension, the rear is an upgraded version of the first VAZ model.

The figure below shows the rear suspension device of the VAZ-2107. Number 1 shows the thrust spring between the axle (4) and the vehicle body. Number 2, telescopic shock absorber damping sudden vibrations. Transverse jet thrust 3, prevents the axle from shifting away from the vehicle axis. Longitudinal rods 5 and 6 fix the position in the direction of travel. This arrangement of nodes allows you to compensate for road irregularities.

Front suspension VAZ-2110

Like any VAZ suspension, the tens' front suspension is independent. The front suspension device of the VAZ-2110 is more complicated than that of classic models... This is due to the fact that the drive of the power unit goes through the gearbox to the front wheels. Therefore, the designers of VAZ had to solve the issue of not only the distribution of the load by the suspension, but also not to let it interfere with the operation of the drive. Here, too, the whole scheme is the result of a phased modernization of the front suspension, from the first version of the front-wheel drive model VAZ-2108. This variation, as the most successful, remained in the variations following the "ten".

Front suspension device VAZ-2110

The suspension kit includes the following components:

• lower arm;
• hub;
• spherical bearing;
• telescopic stand with spring;
• brake disk;
• wheel drive;
• stabilizing transverse bar (on both wheels);
• suspension arm with stretching.

It is the telescopic rack that plays a special role here. Now they are produced in several types. Liquid and gas racks. The principle of operation of the rack is based on a gradual, rather than abrupt, movement of the working rod in the body. This is achieved by in-cylinder bypass valves on the inner rod. Depending on the medium that the valves are bypassed, the struts are divided into hydraulic (liquid on oil) and gas. Usually the manufacturer installs cheaper hydraulic struts. One of the tuning positions of the VAZ-2110 chassis is just the replacement of liquid struts with gas ones. They are more effective and give stability to movement at any speed.

Racks are also used here. But since unnecessary problems in the image of the drive on rear wheels no, it's a little simpler. The rear suspension includes the following units and parts:

The carrier beam is fixed to the car body with a movable joint. That is, the beam has a relative freedom of movement, like a lid hinged downward. The spring and shock absorber successfully dampen sharp vibrations, eliminating sharp impacts of the beam on the body. The main malfunctions of the rear suspension system are usually also primarily the malfunctions of the shock absorber strut. Also wear of rubber expansion joints in movable joints.

Attention! During any inspection of the undercarriage of the car, the mechanic-repairman must without fail check the condition of these parts.

Malfunctions of these components do not just cause discomfort from knocking. They contribute to the destruction of the body. A body repair pleasure is not cheap. It is better to replace the rubber bush on the hinge or even the strut in a timely manner than to pay for the bodywork later.

Suspension of the chassis VAZ-2121 "Niva"

The Russian off-road vehicle VAZ-2121 has all-wheel drive. This was reflected in the suspension of the chassis of the car. It has its own characteristics and slight differences from other models.

Rear suspension Niva 2121

By her own rear suspension bridge "Niva" is identical to the design of conventional classic VAZ models. However, the moving parts have a little more freedom of movement and are manufactured with a large margin of safety for confident movement on terrain where there is no road surface. The new design element is the device of the brake drive pressure regulator. Depending on the position of the machine and rear axle, a lever attached to the axle controls the opening of the rear brake valve. The rest of the suspension differs only in mobility and strength.

Front suspension VAZ-2121

The front wheel suspension is a little more complicated. The front wheels are both driving and steering wheels. Here, too, a larger angle of free movement of moving parts is provided. Therefore, for stabilization, an elastic bar is installed, which is attached to the body. The upper and lower support arms are made in an A-shape and are more reminiscent of the paired suspension arms of a front-wheel drive car than the classics. Despite the apparent fragility of the structure, its strength exceeds the strength of the "classical" structure due to the material and the form of rigidity calculated thoroughly. As in other suspensions, here it is necessary to carefully monitor the condition of the rubber bushings and ball joints.

Telescopic suspension strut VAZ

Telescopic struts replaced conventional shock absorbers with the advent of front-wheel drive VAZ vehicles. They perform the function of not only a shock absorber in the suspension system, but also important element power suspension frame. If the shock absorber only mitigates jerks when hitting bumps or bumps, the suspension strut mounted with a spring also prevents the suspension parts from moving in different directions. Keeps the suspension arms in position.

Therefore, all its parts are made of materials that are stronger than the shock absorber. Therefore, the price of the rack is much higher.

The device and principle of operation of the telescopic suspension strut

In fact, the rack resembles a medical syringe. The body is the barrel of such a syringe. A rod with a piston at the end moves inside. Only in the absence of an outlet, the fluid in the hydraulic struts is usually the spindle oil, which, with the help of valves built into the piston, smoothly moves to the top when compressed. When stretched also

smoothly moves back. Unlike the shock absorber, the suspension strut housing is equipped with cups for mating with a shock absorber spring, which provides additional suspension stability. In addition, depending on the type of rack, the lower attachments of the body to the suspension arms are arranged differently. The strut is not a repairable suspension unit. In the event of a malfunction, it must only be replaced.

Important! When replacing the rack, the spring is reinstalled on it. This can be done only with the help of a special tool - a spring clamping puller, in order to avoid serious injuries.

Brake system of VAZ cars

On the VAZ prototype, Fiat 124, the designers installed the system disc brakes... It is ideal for highways and highways, those that are called federal in modern Russia. However, at that time, there were no roads of this level in the USSR. The vast majority of roads were of poor quality, and did not represent the possibility of high-speed movement. And in conditions of low and medium speeds, disc brakes did not perform well. Therefore, the drum type was adopted, where the semicircular pads were unclenched by hydraulics and pressed against the walls of the drum over a large area. So it was customary to install drum brakes on the classics. They did not become wise by going to front-wheel drive... The first "chisels" VAZ-2108, and after them and 2109, were equipped exclusively with drums.

Switching to disc brakes

However, as time went on, and the situation with the roads began to improve markedly, speed mode increased. The drum brakes were already performing poorly. Installing a full disc braking system, however, meant completely eliminating the sale of new models to buyers in peripheral areas, where many roads still leave much to be desired. The "Solomon's decision" was made - rear brakes remained drums, and the front ones were put on disks. Since then, this formula has been fixed on the VAZ. The only exception is Lada Kalina Sport. This special speed model is equipped with brake discs from the factory.

Tuning chassis and suspension system VAZ

There are no special improvements in tuning the suspension of any brand. A common practice in this direction is to replace drum brakes with disc brakes. But this should be done in the event that a general modernization of the engine and gearbox has been carried out. It is possible to replace some units with products made of lighter and stronger, correspondingly more expensive, material. Another tuning position is the manipulation of the length of the springs. Some owners, striving to give their car the look of a sports car, cut off 1-2 turns from the spring. Others, those who expect to carry heavy loads, on the contrary, "lift" the car with the help of special cushions under the springs, and even buy non-standard ones, with a large number of turns. Both options are unsafe. When cutting, "understating", the car loses a decent amount of depreciation, the shock absorber strut breaks down faster. The body is destroyed, control is deteriorating. When the body is lifted, the machine becomes less stable at high speeds and the risk of overturning increases. In general, tuning a suspension requires careful thought and serious consultation.
