What are the hubs for UAZ? Hubs on UAZ "Patriot": the order of installation on the car

Among the huge number of motorists there are a lot of those who prefer a measured ride on the asphalt covering the search for adventures off-road. Many of them own various UAZ models. These cars are distinguished by the availability of an all wheel drive. In such models as "Patriot", "Hunter", "Loaf", drive 4x4, plug-in. What's all this for? And to the fact that this drive is not always necessary. After all, if motorists and go off-road, then more often on weekends to take a break from the office work routine.

So, for those situations when the all-wheel drive is not needed, put the hubs on UAZ. The main, and however, the only function of these mechanisms is to transmit the torque from the front drive directly to the wheel itself or to disconnect this very connection in the event that there is no need for a full drive.

Why disable all-wheel drive?

Here, at first glance, everything is very simple. For example, it is possible to take a steel rolling in diameter approximately in 100 mm and to fasten to a nave of a wheel. Then you can put the wheels on the drive splines. It's strong, reliable and simple.

However, here the SUV leaves on the asphalt road and, slapping mud, smoothly starts to gain speed. In the ears, the wind is noisy, the engine and transmission are strained to hear the work of the engine and transmission, the driver is already thinking about the nearest long-distance trip, and the front axle, even before leaving for asphalt, was cut off by a specially assigned transfer case lever, and continues to rotate. What is it rotating from? From the speed of the wheels. When the car rides along the asphalt, the wheels rotate the drive and the hinges of equal angular velocities. The latter give this energy to the reducer and the front cardan gear.

In this there is nothing particularly terrible. In most SUVs of the Ulyanovsk Automobile Plant there is a reliable transmission, the stability of which will be sufficient even for very long and large distances in the most difficult conditions. The engine will also be able to easily rotate the nodes, which at the moment are completely unnecessary.

Why would the engine consume excess fuel, because in a full drive in this case there is no need? Why tolerate a small, but still lower dynamic characteristics? What for to subject to additional deterioration knots in which now too there is no necessity? And in the process of motion, various vibrations and noise can appear, which arise as a result of the rotation of heavy masses. If none of this driver needs, then the best way is to disconnect the wheels from the drive. This is the answer to the question whether hubs are needed at UAZ Patriot.

Front Wheel Release Clutch

This is exactly how these devices are properly named in the Russian-language documentation. They are most often fixed on the hubs of the front pair of wheels and serve as a rupture of rigid coupling of the wheel with the drive when it is not necessary for the driver.

Wheeled hubs on UAZ: the device and the principle of operation

So, with the functions of these couplings everything is clear. But how do they work and how are they arranged? To answer these two important questions, you need to know what kinds they are. For off-road cars apply manual and automatic devices. But this division can be considered conditional.

Manual

These products are found on most off-road models of almost all manufacturers anywhere in the world. Hand hubs on UAZ are also very common in our country.

How to use

This mechanism is used to reduce the wear of parts and components in the front driving axle of the car, as well as to save fuel, if you have to travel more often on paved roads. When the driver disconnects the bridge, it is also advisable to disconnect from the hub drive on the front wheels.

How it's done? According to the instruction, which is attached to the car UAZ "Hunter", the hubs must be translated into a special position. Often this position is marked on the body of the mechanism. To do this, using a special key, remove the hood, and then unscrew the bolt from the drive shaft hole. Then it is possible to translate the clutch into a position where the annular groove on the surface rises in one plane with the end part of the flange. Then it is necessary to screw the cap. This is true for all off-road UAZ models. So, how to turn off the wheel is understandable. How to include hubs on UAZ? It must be done by screwing and tightening the bolt.

From all this it can be understood that a coupling is fastened to the end part of the drive shaft. It, in turn, with the help of a special tool can be rigidly connected to the hub flange or rotate independently of the hub. The devices strike their reliability, however, it's quite inconvenient to use such a hub, therefore hubs of such a plan are not used for UAZ "Hunter" SUV. Do not use them for other models that are produced today.

Modern equipment: 2.0 hubs

Now, if you need to turn off or turn on the wheels, just leave the car and simply turn the special switch to the desired position. These positions are only 2: 4x4 or 2x2. Then you can again return to the SUV and continue the journey.

This is how hubs on UAZ are included, which are installed on most off-road cars of this brand and other brands, even foreign ones. As for the technical details, each device manufacturer has its own mechanism.

Advantages and disadvantages

Among the unique advantages that hand mechanisms have, it is possible to distinguish incredible strength. Strength there with a margin. Also, the pluses include simplicity of design, reliability and ease of use.

But, when installing hubs on UAZ, do not forget about the disadvantages. So, for use, you need to get out of the salon and dirty your clean hands about smeared with dirt, and often even with ice switches.

Yes, it is worth saying about the ice. Some manufacturers make switches from plastic. It would seem that this is the most ridiculous material that can only be used in the transmission system. But it is in the big frost that the plastic does not freeze, and this makes it much easier to switch the mechanism to a different mode of operation.

Another advantage of the hand hubs can be attributed to the possibility of including or disconnecting the front axle directly from the cabin in motion, if the hubs (at the UAZ "Bukhanka" or the "Patriot" they are put - without a difference) of the Ulyanovsk Automobile Plant were included in advance. This is sometimes very useful when the car suddenly stopped on a very slippery section of the road or it fell into a mud trap.

To avoid any surprises, most drivers begin to incorporate these mechanisms at the time of the first serious snowfall. Turn off the same spring, when there is already everywhere a dry asphalt. Also turn off the hubs at any time, if you need a very long time to go on dry asphalt. This is a reasonable approach, which is confirmed by years of practice of all those who have already used hubs (UAZ Patriot). Reviews, photos fully confirm this information. With these mechanisms it is easy, convenient and can save a liter of fuel or even more. Many fear that if you use closed hubs for a sufficiently long period of time, then this can be very harmful to a bridge or car. But all this is in vain. On many models, there is a special plug in the package, which ensures a constant transfer of torque to the front axle without the possibility of switching off.

Automatic mechanisms

Now you need to talk about automatic hubs. Their main difference from hand-brothers for the driver is that in order to switch them to the desired position, you do not need to leave the car salon. In order to start the front-wheel drive, connect the bridge directly from the passenger compartment. In rare cases, it may be necessary to press an additional button that controls the hubs themselves.

How it works?

There are several options for work. The drive can be an electric motor installed inside the hull and switching hubs on the UAZ-469 or any other model. A vacuum or a hydraulic system can also be used to control the operating mode of the mechanism.

The most popular among fans of off-road equipment is a hub that can be switched on independently. It turns on mechanically when there is a torque on the wheel drive. Each design has its pros and cons. Below we will discuss them in more detail.

Hubs with electric drive

These devices combine a maximum of reliability, as well as all the simplicity of the hand mechanism, which needs to transmit electricity to the control motor, which rotates with the wheel hub. There is a small problem here - brushes that transmit current, are operated under rather difficult conditions. This is an age-old dirt, complex temperature regimes. Once the system simply does not turn on, and the car at the right time will remain with the rear drive. In this case only tractor drivers will be able to pull the SUV out of the swamp.

Vacuum mechanism

After the all-wheel drive is switched on, the special pump starts to suck out all the air accumulated in the system from the wheel coupling. As a result of this process, the hub is blocked. At the moment when the drive needs to be disconnected, the system will operate on the contrary - reverse the injection of air into the system.

In this design, everything is fine, but up to a certain point. In severe frost, rubber seals can harden, and at the decisive moment the all-wheel drive will not turn on. Judging by the reviews, hubs on a vacuum rarely work long and happily. All due to the fact that through the oil seals all the dirt and swampy liquid will fall directly into the hub and the bearings.

Classic automatic solution

These are probably the most common mechanisms. They are installed on almost all four-wheel drive cars. As a drive here - the transmission itself is auto. This is the principle of the well-known and popular AVM hubs on UAZ Patriot.

When the driver connects the bridge with the transfer case and the torque appears on the semi-axle, the device will close. If you turn on the reverse, the element, respectively, will turn off and then close again, but in the other direction. With each such change of direction, the hub will switch, and this moment will be accompanied by a blow to the transmission mechanisms. If you use the pedals and the lever of the transfer box more dynamically, then the blow will become more serious.

If the driver disconnects the drive from the passenger compartment, it is necessary to drive a short distance in the opposite direction to make the clutch open. If you do not do this, then the hub will be turned on, and you can connect or disconnect the bridge directly from the cabin. This can be done until after the next change of direction it does not turn off.

Hub, if it is open, it will not turn off completely without any problems at the speed. For most SUVs (UAZ is not an exception), the ability to turn on or turn off the drive on the fly is determined only by the design of the transfer case. For this, the synchronizer on the drive gear on the front axle must be installed in the system.

So, such a hub is quite comfortable and convenient, but only where there are really difficult conditions. The mechanism requires careful handling. Raskachka machines can reduce its life up to immediate breakdown. To disconnect, it is necessary to drive a little bit in reverse.

Market offers

In the process of market research, five types of products for all UAZ off-road models come to the eye. We consider only those of the possible options that are available in free sale.

The Oldest Product

Until now, the car market can buy the oldest models made at the Ulyanovsk plant. These wheel switches are still installed on the cargo models. The sharp slots of the coupling engage with the inner sleeve. The bush, in turn, is put on the splines on the semi-axle and fixed with a special bolt. Bolt is the basis of everything. These products are maximally available due to the constant availability in stores and low cost - the price is only 500 rubles.

Elmo products

This company produces hubs, which complete "Hunter" and "Symbirs". These products are ideal for UAZ and most often found on sale. Products are available in several versions - with a decorative switch and simple hubs on the UAZ. The photos do not impress with special beauty, but the detail is not of this kind. The price is from 920 to 960 rubles. This is also a very affordable cost.

"Stead"

These products are very similar to the previous ones, but if you look closely, these have a slightly different shape and color. In addition, the mechanism is characterized by a lighter weight. They are made in Ufa. The price for a pair is about 700 rubles.

ADS

There are on sale hubs "ADS" on UAZ. Drivers are generally satisfied with the work, but not all discs look aesthetically pleasing. Somewhere strongly stick out, that spoils the whole view. But in general, these details look very solid and strong. On the staff discs with these hubs will not be able to install a cap. But they fulfill their function, and more of them are not required.

AVM

Probably, this product should not be presented. Hubs AVM on the UAZ "Patriot" and the rest of the line of models produced in Brazil. They are very easy to learn. High quality is visible even on the case. It is felt that the device and the mechanism really worked. Also, the mechanism is well equipped. The cost is more than 5000 rubles. But these costs are fully justified. The well-known automobile edition conducted a number of tests of all available hubs on the market. And the test results showed really high quality of these products. Both manual and automatic models perfectly and clearly perform their functions.

Wheeled hubs on the UAZ "AVM" are available in four versions. All of them are suitable for all off-road models, even including the GAZ-69. In the lineup, there are both automatic and manual models, both conventional and reinforced.

In order to verify the quality of this product, it is necessary to get acquainted with the numerous reviews, which are written by the owners of off-road equipment manufactured by the Ulyanovsk plant. Those who have at least used these mechanisms a little assure that AVM products are without exaggeration the best hubs on UAZ Patriot.

In addition to these products in the auto shops you can see the system "Rus" and "Reef". These are low-level mechanisms, but they are also trustworthy.

Installation

The order of replacement of the coupling is very simple. First of all, it is important to replace correctly the mechanism that was installed earlier. For this it is important to take into account the level of complexity of unscrewing the bolts.

Using a metal brush, clean the exterior surfaces of dirt. The end head is unscrewed by the bolts. If the bolt does not give way, you can use a pneumatic tool.

Then carefully work the surface of the hub. Here, remove the remnants of the old gaskets. Clean dirt and corrosion. With the help of compressed air, clean the holes for the fasteners. It is recommended to apply a little grease to the bolts.

Mounting the new hub, it is not superfluous to lay the seal between the hub and the coupling on the sealant. Although the manufacturer and assures as a gasket, it is still better to create additional protection. Then the clutch is installed, but first you need to install its intermediate part. Then the mechanism of inclusion and a lining is established. Do you need hubs on UAZ Patriot? Definitely needed by those who love off-road and difficult conditions, but at the same time regularly travels on hard surfaces.

So, we found out what hubs represent for SUVs produced by the Ulyanovsk Automobile Plant. We hope that the information provided will be useful to you.
