In the off-road car market, in particular in the Russian Federation, the French car Renault Duster occupies a fairly good position. A machine that has four-wheel drive, is able to overcome off-road rather easily. At the same time, the car owner drives calmly, and does not think that at the slightest exit from the road, the car will get bogged down. How does four-wheel drive work on this model, and what features does it have, and, of course, what is its principle of operation? Let's try to figure it out now.
How does four-wheel drive work
The four-wheel drive scheme on the "French" Renault Duster includes several elements - a rear differential, a transmission, an electromagnetic automatic clutch and transfer case... How do they interact with each other and how to turn on the four-wheel drive?
Plug-in or permanent four-wheel drive is installed on the model we have designated, how is four-wheel drive turned on? The answer to such a question will be controversial. So, the transfer case is built into the transmission, as it were, and the differential is already controlled automatically through the clutch microcontroller.
In this car, control is carried out using an electronic selector, which is located on the center console. How does four-wheel drive turn on? The selector includes only 3 modes - clutch lock, mono drive system and automatic clutch.
When you switch front-wheel drive, then the clutch control is deactivated. By the way, this is why it decreases several times, because in this case the generator does not need to supply the automatic machine and the electronics of the rear gearbox, as well as all its mechanisms.
So, in automatic mode, the automatic clutch is independently activated, the control of which does not depend on the driver, but occurs due to special wheel slip sensors, which are located in the Renault Duster in the ECU. All this means that when the front of your model begins to slip, then instantly the torque begins to be transmitted to rear wheels and turns it off at the right time. This is how the all-wheel drive device looks like.
At the same time, the manufacturer strongly recommends using not the all-wheel drive system constantly, but the automatic mode, in the presence of ice on the road, thanks to this, your safety while driving will increase several times.
During the blocking mode of the automatic clutch, its operation is carried out at a constant level. So, all sensors that are able to somehow affect its work are instantly turned off, in turn cardan shaft will be connected to the gearbox, and will ensure its rotation.
Considered according to numerous reviews from car owners Renault Duster, with prolonged use of the blocking mode, the coupling may fail and bend.
Owner reviews
Many Renault Duster car owners speak differently about the all-wheel drive system, many tell in detail how all-wheel drive works, and how to correctly use this function in their car. Others help with their advice on when and how to engage four-wheel drive, and so on. This allows potential buyers to draw their own conclusions about the Duster. And often, positive feedback much more than negative ones. Here are some examples.
Alexey, driving experience 9 years:“I bought my Renault Duster back in 2014, for all the time that has passed, I have driven 58 thousand kilometers. Often I go fishing, hunting, to the dacha, that is, where an ordinary car will not get. I can say for sure that the car is doing just fine with its declared functions. Of course, not everything works perfectly, but what is there is enough with the head. There were no breakdowns, but they say that the blocking function should not work all the time, otherwise breakdown cannot be avoided. "
Pavel, driving experience 4 years:“I am not satisfied with the all-wheel drive system at all. At 60 thousand mileage, the clutch flew. The car was under warranty, the dealer quickly changed everything, and if it weren't for the warranty, it would have cost me a lot. Another fuel consumption is 3 liters more than that of a car with front-wheel drive, but with the same power plant... I believe it is all about how the clutch works. I read a lot of reviews, I realized that this is normal. I want to sell my car and buy a front-wheel drive version. "
Outcomes
Drawing a conclusion on the numerous reviews of the owners of the "Frenchman", the all-wheel drive version provides a large number of possibilities that are not available to the owner of the one-wheel drive version. If you are familiar with the modes and operating principle of the clutch, then you can easily come to comfortable driving on rough terrain, without worrying about the large and need for frequent transmission repairs.
With the entry of Renault Duster cars into the domestic market, it became very popular. This is due to the fact that for relatively low money, the consumer receives a high-quality crossover with all-wheel drive. For many car enthusiasts, the 4x4 function is a must, since they have to drive off-road quite often. This is especially true of farm and forest land. But, what is the principle of all-wheel drive on Renault Duster?
Enabling all-wheel drive
First, let's consider not the technical side of the issue, but the functional one. Since modern automotive trend strive to reduce fuel consumption, then on cars, switches are often installed from all-wheel drive to conventional.
Renault Duster has not lost this useful functionality either. So, in the car there is a washer-switch, which allows you to turn on different modes. Let's consider the question in more detail:
- Lock function. This is just four-wheel drive. It locks the distribution clutch and there is a forced load on all axles of the vehicle. When using the Lock mode, it is not recommended to drive faster than 70-80 km / h in order not to cause breakage of the lock-up clutch.
- 2WD function. The name itself speaks for itself. This mode only engages front-wheel drive and is ideal for highway driving.
- Electrofusion button in the "2WD" mode
- Electrofusion button in the "AUTO" mode
Thus, it can be seen that both the control unit and the driver himself can choose which mode to drive.
The principle of all-wheel drive on Renault Duster
If we talk about the principle of operation of rear-wheel drive, it is necessary to understand some technical and design features Renault Duster. In the case of front-wheel drive, all the torques go through the CV joints to the front wheels. But how does the rear one work?
In this case, a transfer case is installed on the car, which redirects torque to the rear wheels. The system was invented a long time ago, back in the distant 50s, but the principle has remained to this day, although these devices are being improved all the time.
Classic scheme of plug-in all-wheel drive
A clutch is installed in the rear gearbox Renault Duster, and if it is blocked rear drive does not work. It can be turned on both forcibly by the driver and with the help of an ECU. Let's consider everything more simply and clearly: the engine supplies torque to the gearbox, and from there it goes to the junction box.
Through the propeller shaft, it enters the rear gearbox, in which there is a clutch regulator for engaging the rear drive. If it is on, then the four-wheel drive works, if it is off, then only the front one. The rear gearbox has its own oil, which requires replacement.
Let us remind once again that it is not worth forcibly using the clutch-switch for a long time, since it can fail under power load. Therefore, the AUTO mode is considered the most optimal to use.
Where necessary, it is worthwhile to briefly turn on the manual mode, and when it becomes unnecessary, switch back to the AUTO mode.
The all-wheel drive operation was simple and straightforward. Of course, if the clutch fails, you will have to replace the entire assembly, which is expensive, so you should follow the rules for using the 4x4 mode.

Today four-wheel drive vehicles gained particular popularity, since their cross-country ability is better, and our roads are conducive to the use of just such vehicles. But which model should you choose? Renault Duster today confidently storms not only the automobile stage, but also the roads of our vast homeland.
Why exactly he?
Now Duster, whose four-wheel drive has already been discussed repeatedly by many popular automotive magazines, can have three driving modes:
In the first case, the drive is carried out exclusively to the front axle. The second mode automatically engages four-wheel drive. This means that the vehicle does not constantly use this system, it is connected only when there is a real need for it, for example, at moments of slip and so on. The third mode is the four-wheel drive state itself. True, in this case you cannot move at a speed of more than 80 km / h. If this limit is exceeded, the clutch will automatically stop blocking.
Duster all-wheel drive and its features
It is noteworthy that this model has no crawler gears at all. In some cases, they are successfully replaced by the use of the first gear. As for the direct handling, there is simply no vehicle equal to the specified vehicle.
The Duster, whose all-wheel drive is developed on the basis of the latest scientific achievements, is one of the most powerful representatives of its class today. According to a huge number of motorists who have tested this vehicle, this is a high-spirited and powerful device that holds the road excellently, confidently making its way where there are essentially no roads.
An excellent wheelbase, a confident engine, excellent acceleration - this is what the modern Renault Duster can boast of. It is noteworthy that some experts consider all-wheel drive to be an unnecessary add-on on smooth asphalt. Nevertheless, modern car The Renault Duster is an example of how an SUV copes well with urban conditions.
Main conclusions
Thus, the specified vehicle is excellent. vehicle equipped with all-wheel drive. Wherein this system here it is really implemented at the highest level, thanks to which the vehicle itself is the owner of a huge number of various international programs. In addition, the car is very popular among both avid motorists and those who are just a beginner. The car is not only comfortable to drive, it is extremely easy to operate, since the four-wheel drive is excellently regulated in automatic mode, thanks to which this vehicle can rightfully be called a smart car.
Four-wheel drive versions of cars are the most popular today due to the fact that it is a truly comfortable car that is suitable for absolutely any roads and off-road conditions. At the same time, Renault Duster is today considered the most profitable acquisition among classmates with similar technical characteristics... That is, when buying, it will be possible not only to acquire a high-quality vehicle, but also to really save money.

Currently, the most popular car class is the crossover. This vehicle combines the charms of a passenger car and an SUV, and therefore is very practical and versatile. Renault Duster all-wheel drive is one of the most popular crossovers not only in the Russian, but also in the world market. The car managed to get a huge demand due to its unpretentiousness and favorable cost.
In addition, Duster all-wheel drive is distinguished by excellent cross-country ability, which has always been more than relevant for Russian motorists, because everyone knows our road problems. Duster did not immediately become an all-wheel drive car, and the device of the car is very specific. Let's try to figure it out with you, and at the same time it will become clear why the car is so popular and practical.
In response to the question, what kind of drive does Renault Duster have in modern version, we can safely say that it is variable. After all, the Renault Duster all-wheel drive scheme is not entirely standard. So, the car has an optional drive: either full or only front-wheel drive. As a rule, when driving on better roads, it is recommended to use the first option, and if you want to save fuel, or there is simply no need to use the 4x4 mode, you can turn off the rear-wheel drive and drive safely, for example, on a city road.
Therefore, the answer to the question of what kind of four-wheel drive Renault Duster has: permanent or plug-in, you can safely choose the second option. This solution cannot be called new, because on some others compact crossovers the same principle is involved. But Renault all-wheel drive differs, first of all, in price, because the car is much cheaper than competitors with similar capabilities.
Secret 4x4
To understand the work of the all-wheel drive on the Duster, let's talk about the design of the car. So, the torque is supplied to the front-wheel drive in the standard way: through the CV joints. But with rear circuit more complex. The torque is transmitted to it by a transfer case, which is equipped with a variator. It can either turn on or off the clutch responsible for the rear pair of wheels.
With the clutch turned off, Renault Duster receives four-wheel drive, and if it is turned on, the car will become front-wheel drive. Everything is simple and convenient! The whole secret lies in the transmission and electromagnetic clutch Renault Duster 4x4, the device of which has such a variable system. So you can easily convert your car to 4WD, this can also happen automatically using the ECU.
Clutch control
Thanks to such a system, Renault Duster all-wheel drive has several modes at once, which are responsible for the operation of the clutch-switch and, accordingly, for supplying torque to the rear wheels of the car:
Lock mode. This option allows you to turn on the all-wheel drive mode of the machine, because it blocks the distribution clutch. This enables the forced distribution of torque to all axles, so that the car goes into 4x4 mode. It should be borne in mind that when Lock is activated, you should not drive faster than at a speed of 80 km / h, which can lead to failure of the clutch. The fact is that if it breaks down, you will have to replace the whole unit, and it will come out oh, how not cheap!
Auto mode. When it is activated, the ECU is responsible for turning the all-wheel drive on and off on Renault Duster. If the surface on which the car is driving is bumpy, then the car goes into 4x4 mode, but when driving on a good road, the all-wheel drive option is enough. As a rule, motorists use the Auto mode constantly, because only a few control the distribution clutch manually;
2WD mode. This function is used in cases when they want to transfer Renault Duster to a front-wheel drive format, which is optimal for driving on normal roads. It activates the clutch, and therefore the torque to the rear wheels is no longer supplied.
As you can see, controlling drives on Renault Duster is more than simple, especially if you use auto mode... Otherwise, the car does not differ in non-variable crossovers, so there is no special specifics when driving this crossover. Renault Duster all-wheel drive suspension is independent, which significantly improves cross-country ability, comfort in the cabin when driving over bumps.
So, with a Renault Duster car, you will always be able to control the drives, turning your car into an SUV or an analogue of a passenger car. This can be done simply using a washer with the listed modes, which are responsible for the operation of the distribution clutch. To drive off-road, you use the Duster 4x4 option, but on the highway it is much better to turn it into a 4x2 option, since this will significantly save fuel, and the risk of breakdown is significantly reduced.
With proper control of the Duster, the car can ideally pass on any roads, and operation will not cause any problems. This variable crossover from Renault is the best option in its price range and is undoubtedly worthy of the attention of Russian motorists.
How Renault Duster drive works What operating modes does the all-wheel drive transmission of this crossover have? We will try to answer all these questions now.
Scheme of work Renault drive Duster pretty straightforward. The torque is transmitted to the gearbox, and from there it is distributed between the front wheels by means of shafts, at the ends of which there are hinges of equal angular speeds. More precisely, on the outer ones there are ordinary CV joints, and on the inner “grenades” the design is slightly different, there are tripods inside. This allows the axes to move with some clearance. If it is clear with front-wheel drive Renault Duster, the scheme of its operation differs little from the principles of operation of any front-wheel drive car with a transverse engine. The simplicity of the design is a big plus for such a budget car.
And here four-wheel drive on Renault Duster 4x4 arranged a little more complicated. The gearbox contains a compact transfer case (indicated by an arrow in the photo), from where the torque is transmitted to the rear gearbox through the propeller shaft in a constant mode. But in front of the gearbox there is an electromagnetic clutch (the location of the clutch is also indicated by an arrow), which transfers torque further, or does not transfer it, that is, the cardan shaft simply rotates idle. And already from the gearbox along the same axes with CV joints at the ends, the torque is transmitted to the rear wheels. We look at the photo of the rear part of the Renault Duster 4x4 transmission.
Such Renault Duster transmission design allows you to operate the drive easily and naturally. To control the operating modes of the drive, there is a switch washer in the interior of the crossover, here it is in the photo. One easy movement can be made from front wheel drive crossover, four-wheel drive off-road vehicle or entrust everything to automation.
- In the “Lock” mode, an electromagnetic clutch is triggered and the torque goes through the gearbox to the rear wheels.
- In the “2WD” mode, Duster's front wheels become leading, the propeller shaft, which should transmit torque to the rear gearbox, rotates at idle.
- In the “Auto” mode, the crossover itself determines when to connect rear-wheel drive. Typically, the electromagnetic clutch is triggered when the front drive wheels slip.
It is worth noting that the most dynamic and at the same time economical is “2WD”, with partial or full engagement of all 4 wheels, fuel consumption increases. And in the mode of full blocking of the “Lock” electromagnetic clutch, the crossover speed should not exceed 80 km / h. Off-road 4x4 mode can overheat the clutch, resulting in transmission failure. This is how the Renault Duster four-wheel drive works.
