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 gets a high-quality all-wheel drive crossover. 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?

How Renault Duster all-wheel drive works is described in the video:

First, let's consider not the technical side of the issue, but the functional one. As the current automotive trend tends to reduce fuel consumption, cars are often equipped with switches from four-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 switch on different modes. Let's consider the question in more detail:

Thus, it is clear that both the control unit and the driver himself can choose which mode to drive.

The principle of four-wheel drive on Renault Duster

If we talk about the principle of rear-wheel drive operation, it is necessary to understand some of the technical and design features of Renault Duster. In the case of front-wheel drive, all torque goes 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 plug-in all-wheel drive scheme

A clutch is installed in the rear gearbox of Renault Duster, and if it is blocked, the rear drive does not work.

It can be turned on both forcibly by the driver and with the help of an ECU. Let us consider everything more simply and clearly: the engine supplies torque to the gearbox, and from there it goes to the junction box.

Detailed diagram of all-wheel drive on Duster

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. AT .

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 worth briefly turning on the manual mode, and when it becomes unnecessary, switch back to the AUTO mode.

conclusions

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.

How does Renault Duster four-wheel drive work?

general information

In general, the drive system of this car model is quite simple and it is not difficult to understand it even for a non-professional. The distribution of torque between the wheels is carried out from the gearbox. CV joints are installed on the outer ends of the shafts, which receive equal angular velocity, and on the inner ends there are tripods. This mechanism of operation does not represent anything new in terms of development; the scheme is borrowed from the famous Nissan Quashkai.

Operating modes

The most basic mode is called 2WD, which includes the operation of only the front wheels and is recommended for driving on high-quality and dry road surfaces. This mode provides economical driving in terms of fuel consumption and a comfortable travel speed.

Automatic operation determines the best grip on the ground. It is mainly used on highways and city roads. In unfavorable weather conditions, for example, during rain, the clutch independently determines at what moment it is necessary to connect the rear wheel drive.

In a mode called LOCK, the clutch is locked and torque is supplied to the rear wheels, so the car becomes full drive and ready to overcome the off-road. However, this function is recommended for operation at reduced driving speeds of up to 80 kilometers per hour.

Outcome

Owners of a Renault Duster car must independently, depending on the situation, choose the optimal drive mode and remember that the most economical driving is obtained in 2WD mode, and it is advisable not to stay in LOCK mode for too long, so as not to overheat the clutch, which can lead to a breakdown of the mechanism. especially since repairs at the current price of Renault Duster 2014 can be very expensive!

All entries

Currently, the most popular car class is the crossover. This car 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 of what kind of drive Renault Duster has in the modern version, we can safely say that it is variable. After all, the Renault Duster all-wheel drive scheme is not quite standard. So, the car has an optional drive: either full or only front-wheel drive. As a rule, when driving on not the best roads, it is recommended to use the first option, and if you want to save fuel, or simply do not need to use 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 some other compact crossovers use the same principle. 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 how all-wheel drive works on 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 the rear, the scheme is more complicated. 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 gets 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, it 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, an 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 is no longer supplied to the rear wheels.

As you can see, controlling drives on Renault Duster is more than simple, especially if you use automatic mode. For the rest, 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 will be able to perfectly 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 worksWhat modes of operation does the all-wheel drive transmission of this crossover have? We will try to answer all these questions now. Moreover, the question interests many Russians who dream of an affordable all-wheel drive crossover.

Renault Duster drive scheme 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. Most likely, the same scheme will be used on Renault Duster in a new body, which will appear in our country in 2018.

But four-wheel drive on Renault Duster 4х4 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 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 the torque further, or does not transfer it, that is, the cardan shaft simply rotates to 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.

And here is the main element of the all-wheel drive transmission in the context. In this photo, you can very well see all the internal parts of the clutch and rear gearbox.

Such renault Duster transmission design allows you to operate the drive easily and naturally. To control the operating modes of the drive in the interior of the crossover there is a switch washer, here it is in the photo. With one easy movement, you can turn a front-wheel drive crossover into an all-wheel drive SUV or entrust everything to an automatic.

• In the "Lock" mode, an electromagnetic clutch is triggered and the torque goes through the gearbox to the rear wheels.
• In the "2WD" mode, the front wheels become the leading ones for Duster, 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. Normally, 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 electromagnetic clutch "Lock", the crossover speed should not exceed 80 km / h. Off-road 4x4 mode can overheat the clutch, resulting in transmission failure. This is how Renault Duster's four-wheel drive works.

The four-wheel drive Renault Duster SUV has a wide range of trim levels. Let's start with the cheapest - Access 4x4 1.6 MKP6... This includes:

How four-wheel drive works

Consider the principle of four-wheel drive operation - it includes three operating modes: front-wheel drive, AUTO mode and LOCK mode... As the name suggests, the first mode means using only front-wheel drive. This is very convenient, because there is an opportunity to save fuel, which is important. The second mode has the advantage of providing better grip as well as handling. The third mode is a mode in which the torque is automatically distributed between the axles. It is best to use this mode when driving on surfaces such as sand, mud, ford, ruts or snow.
