The principle of operation of the Distribution on UAZ Patriot. Duty box DYMOS TF120E2 with electrical control on UAZ Patriot and UAZ pickup, characteristics, inclusion of modes, operational features. Appointment of transfer transmission

Any SUV with full drive is necessarily equipped with a handout. Not exception and "UAZ Patriot". Distribution in this car until 2014 is the most common mechanical lever-driven. In models released on the market after 2014, a new handout transmission has been established. It is manufactured in Korea Hyndai-DayMos. Let's look at the design and device of the mechanical domestic box, and then the new Korean.

Appointment of transfer transmission

This node is needed to divide the rotational moment for two axes of the off-road car. But that's not all. This unit allows you to increase the rotational moment in the process by complex sections due to the reduced transmission.

This box is two-stage and capable of increasing the number of transmissions of the gearbox twice. This allows you to more conveniently exploit an SUV in the most difficult conditions.

Where is?

On the "UAZ Patriot" razdatka is directly near the gearbox. The front and mechanism is connected using cardan shafts. The design is enclosed in the housing from the cast iron. Inside this case, gears, shafts, as well as a transmission lever are installed.

Device

So, inside the dispensing box there are a leading shaft, the shafts of the drives for the rear and front axle, the gear, as well as down. The rotational moment the transmission gets directly from the drive shaft of the checkpoint. The dispensing box is attached to the back of the gearbox using special connecting elements. This node is centered along the outer part of the bearing - it is a double row and is on the checkpoint, on the secondary shaft. At the rear wall of the crusher, there are elements of the parking brake.

Inside the unit there are two shafts. This is a leading and intermediate. They are fixed at the expense of bearings. The design also includes drive shafts for the front and rear axles. They installed straight gears, thanks to which engaged.

From the checkpoint in the dispensing box includes a leading shaft with slots at the end. In one plane with this shaft, a drive element for the rear axle is installed. It is also fixed using bearings. There is a speedometer gear between the rear axle shaft bearings.

The rotation of the intermediate mechanism is provided by two bearings. One of them is a ball-type, the second is roller. Front bridge drive shaft along with the gearbox is at the bottom of the box. It rotates due to two ball-type bearings.

On the "UAZ Patriot", the razdatka is also equipped with a lever by which the driver can control the operation of the transmission. The control mechanism is two rods and two forks. These elements are at the top of the node. With the help of the lever, you can enable or disable the rear and front axle or to use both bridges.

Also, the mechanism includes glands, seals, fittings, flanges, a plug for oil drain. The device is undemanding to service. However, it is periodically necessary to carry out various preventive and repair work. Most often, the new oil is poured into the "UAZ Patriot" distribution, the glands or worn gears are replaced.

New razdatka

As already noted, the "Patriot" model after the 2014 model year was equipped with new boxes from the Korean Hyundai-Dymos brand. But in fact, the mechanism is produced in China under license. This rattage has a good pedigree. It is enough that this mechanism was developed in the 1980s by Japanese engineers. Almost the same disasters were established on and this suggests that the design is quite successful. Once it is suitable for the Japanese and Koreans, then for Patriot will be just right, they say the reviews of the owners.

Mechanics are simple and understandable. And what can be said about the design of the electric? Transfer boxes of the past generation were purely mechanical. The four-wheel drive connected by the driver's hand force, which installed the selector to the desired position. Distribution "UAZ Patriot" from "Daimos" electric. To switch to the desired mode, it is enough to rotate the washer or the rotary controller. Everything else will do an electric motor that controls rods and forks inside the mechanism.

Owner reaction

The lack of a familiar lever in the cabin at the owners causes dual feelings. This item is even in serious imported SUVs. But on the other hand, the round selector looks more modern and elegant. His reader can see the photo below.

This is a normal approach of the manufacturer who would like to catch up with world automakers.

Features of the Korean "Daimos"

Experienced owners of SUVs with the installation of a new distribution will immediately notice the lower noise level. Due to the application in the design of a multi-row Morse circuit in the cabin, it became much quieter. The chain itself reader can see the photo below.

By car "UAZ Patriot", the Korean Distribution does not reduce the clearance - under it to the land of as many as 32 centimeters, which is even more than above the main transmission. It will not be the "bottle of neck", which limits the possibilities of passability.

Numerous test drives show that this mechanism would not prevent additional distribution protection. "UAZ Patriot" has no such option for such an option. The electric motor protrudes outward. And when moving on ravines, swamps and other obstacles, it can be easily damaged.

As for the technical characteristics, the overall dimensions of the mechanism increased, the torque increased due to other gear ratios. This was the reason for the need for the front, the front was strengthened, and the rear is shortened. Also removed the intermediate support. This is a big plus in favor of the Korean-Chinese mechanism. The design is more reliable, and the vibrations of the Kardan cannon.

The mechanism housing is made of aluminum. And inside it is not familiar gears, but a chain. Due to the use of another design, gear ratios of a reduced row increased by 31 percent. Now the gear ratio is 2.56. The car can move more confident over rough area due to increased torque. In mechanical versions, this was sought with tuning.

Advantages and disadvantages of electric RK

The advantages of the new electrical structure include another, more efficient gear ratio, reduced noise level and vibration when driving. Also, advantages include simplicity and ease of management of modes. The disadvantages include the increased price and mass of issues related to the maintenance and repair of this mechanism on our service station.

Mechanical dispensing box: tuning

On UAZ cars "Patriot", the razdatka can be modified with tuning. So, with the replacement of gears, you can adjust the torque on low and direct transmission. The design is modified to eliminate the noise.

There are modifications that solve the problem of self-showing in addition, the design of the box does not differ high reliability and sometimes you need to strengthen its mount to the body. You can also redo the box so that it allows you to completely turn off the front axle.

Typical malfunctions

Among the possible breakdowns, there are noise appearance, the failure of gears, leaks through the glands, the destruction of bearings. These issues lead long trips with incorrectly pumped wheels. Also, the faults often leads the front axle included for too long. Connect it only if necessary. If the "UAZ Patriot" rattage (dispensing box) is poorly fastened to the body, then this may cause noise.

Low Bearing Quality is one of the problems of this mechanism. Due to low quality, these details often fail. Often, breakdowns are associated with low oil level or its absence inside.

By car "UAZ Patriot", the repair of a new sample dispensing may be needed for the same reasons. Owners declare a problem with chain and bearings. However, despite these figures, sales of such cars indicate good demand for dispensing boxes with an electric drive. These machines are sold much better than the basic versions equipped with a mechanical domestic distribution.

Conclusion

So, we found out how the transfer transmission is arranged on the machine "UAZ Patriot" and which it has features. As you can see, this mechanism significantly increases the characteristics of the SUV patency. After all, it is the distribution that includes a reduced range of transmissions and blocks

4L mode - reduced transmission 2.542: 1, drive to all wheels, is used when overcoming difficult sections, lifts or descents of large steepness, off-road, when towing in complex road conditions, especially if elevated traction on wheels is required. On the inclusion of 4L mode, the burning indicator 4L signal in the instrument combination.

Features of the operation of the DYMOS TF120E2 reduction box (F041EM) on UAZ Patriot and UAZ pickup.

Using the DYMOS TF120E2 distribution box (F041EM), you can move in both the full drive mode and only rear. The full drive mode is recommended to be used when driving through the snow, dirt, ice, and in the case when a large thrust is needed, as well as when the clutch of the wheels of one rear axle is not enough for the confident movement of the car. Select the desired mode of operation allows switching box mode switch.

When switching to the full drive mode, light mechanical sounds and vibrations are possible in the dispensing box, it is not a malfunction. Movement with the front axle on the smooth and dry roads leads to a limitation of the rotation of the controlled wheels and the appearance of vibration when the steering wheel is rotated. The movement of the car with an inclusive bridge on smooth roads causes increased fuel consumption, noise, and is also the cause of increased wear of tires and transmission nodes.

Any switching modes of a dispensing box must be performed only when the engine is running. The inclusion and turning off the 4H full drive mode can be performed both on a fixed car and while driving in a straight line, in the absence of wheelchair. Turning on and off the full drive mode with a reduction transmission 4L is performed only on a fixed car.

The rotation of the DYMOS TF120E2 dispensing switch switch (F041EM) is selected movement mode: with the drive to the rear axle, with the drive to all wheels on the increased transmission, with the drive to all wheels on the reduced transmission. In the initial position 2H, the display of the transfer boxes in the instrument combination is missing, the drive is carried out only on the rear axle.

Changing the movement mode from 2H to 4H, connecting the front bridge in the dispensing box.

Let the accelerator pedal, press and hold the clutch pedal. Transfer the switch handle from the 2H position to 4H. With successful switching, the 4H symbol is turned on in the instrument combination. Release the clutch pedal. At the same time in cases if:

- Attempts are being made to turn on the full drive mode at the time of significant sketching of the rear wheels relative to the front,
- The movement is made in the presence of a pressure difference in the front and rear wheels, greater than the manual is prescribed,
- immediately before turning on, a turn with a minimum possible radius or an inclusion attempt is carried out directly during the rotation process,
- In other exceptional situations, when which the front and rear wheel drives occur at the time of turning on the full drive, different rotational speeds.

It is possible to switch the system to emergency mode, a sign of the presence of which is the simultaneous inclusion of 4WD check, 4H and 4L alarms in a combination of instruments. In this case, only the rear wheel drive remains active. To enable 4h mode in this case, you must translate the switch to the 2H position and re-enable 4H mode.

Changing the motion mode with 4H to 2H, turning off the front bridge in the dispensing box.

To turn off the full drive mode 4H and turn on the drive to one rear axis 2H, you need to release the accelerator pedal, press and hold the pedal, translate the switch handle from position 4H to 2H. If the switch is successful, the 4H character in the instrument combinations goes out. Release the clutch pedal.

Changing the Motion Movement with 4H by 4L, inclusion of reduced transmission in the transfer box.

To turn on the full drive mode with a lower transmission 4L, the full drive mode of 4H must first be turned on. Next, you need to stop the car, press and hold the clutch pedal. Translate the switch handle from position 4H, through the 4L position to the uncomplicated position "" and hold it to turn on the 4L warning device in the instrument combination.

After turning on the 4L alarm in the instrument combination, release the switch handle, it will occur its self-reforestation to the 4L position. Start movement, smoothly release the clutch pedal. If the engine is stopped in 4L mode, before starting movement, you must make sure that after starting the engine, the 4L motion mode is preserved on.

Changing the Motion Mode with 4L by 4H, turning off the reduced transmission in the dispensing box.

To turn off the full drive mode with a downstream transmission 4L, you must stop the car, press and hold the clutch pedal. Then translate the switch handle from position 4L to 4H. After turning on the 4H signaling device in the instrument combination, you can start moving, smoothly release the clutch pedal.

UAZ Patriot refers to cars of the SUV class, and it follows from this that it must be a complete drive of all four wheels. Indeed, the SUV is equipped with such a function that gives him the opportunity to get out of any puddle, swamps and other types of obstacles found on off-road. It is about this supplement for an SUV and will be discussed in this material. Consider how the four-wheel drive works and how it is properly included, so as not to harm the car design.

Real SUV

It is known that the four-wheel drive on the car is, then a pleasant addition to the mainly vehicles of SUVs, with which you can get out of any swamp. But a minus of such a phenomenon has always been considered a greater consumption of fuel at the time of incorporating this system. The main advantages of this system are:

the best adhesion of the vehicle with the road;
motor efficiency;
fast start;
power increase;
increases the permeability;
the best control parameters.

From the disadvantages, in addition to the increased twice of the fuel consumption, you can also note the difficult design of this system, which entails a considerable cost of the device.

Armcharge lever

There are three types of systems for cars in nature:

Constant;
With automatic connection;
With manual connections.

UAZ Patriot has four-wheel drive, that is, which is turned on manually. It has its advantages:

fuel economy;
inclusion only if necessary;
the cost of such a design is lower than automatic.

So, the main leading device in the UAZ Patriot is the rear cardan, that is, the SUV movement is driven by the rear axle. The front wheels are driven when the system is disabled.

Also, this species is the best solution for powerful SUVs, which contributes to the distribution of torque in 50 to 50 ratios.

Works full drive as follows:

From the motor, the torque is transmitted directly to the box, and from it to the distribution.
The distribution contains such a device as an inter-sieve differential, with which the distribution of torque between the front and rear axle is carried out.
When the front drive turning on the front drive lever is turned off, the torque is distributed only to the rear axle. When included - on both.
The torque enters the rear kandan (and, if necessary, the front) bridge, then the transmission is carried out on the gears of the intercole differential.
Directly through the semipes, the torque is transmitted to the rear wheels and when the lever is turned on - and on the front.

The presence of inter-axis differential lock is mandatory on systems with a constant type of full drive. At SUV, UAZ Patriot has one drawback (if it can be considered), which is that this system cannot be operated for a long time. That is, a four-wheel drive can only be included with a strong need: when moving along a soil wet road or in the snow. If a long time to exploit the four-wheel drive on the UAZ patriot SUV, it will lead to the appearance of noise in the system, vibrations and, of course, to increasing the fuel consumption.

Manual type of full SUV drive UAZ patriot is carried out directly by pre-switching the hub couplif. There is a lever in the cabin, which turns out to be an impact on the transfer box, thereby incorporating the mid-sieve differential. As the inclusion occurs, and the main features of this process will consider in more detail.

Turning on the full drive

So, having understood in important questions about how a four-wheel drive is a Patriot and how its operation is carried out, attention should be paid to manual management of this system.

To properly include a four-wheel drive on the UAZ Patriot SUV, you should know the order of these actions, which will look at further. To properly turn on the 4x4 system, it is necessary:

Initially, turn on manually, which we have already considered earlier. These clutches are placed on the front wheels and to include them, you need to translate the pointer to the right on the left wheel, and on the right, on the contrary, to the left.
At this stage, you can read the front-wheel drive on.
Now it turns on by the dispensing lever four-wheel drive and moves. If you need to increase the passability, you should switch the arm of the dispensing box, thereby turning on the reduced transmission.
When an obstacle is already behind, and is very easy to use the 4x4 system, then you need to turn off the system in the same way. For this, the speed-up lever is returned to its original position and the hubs are disconnected.

Designation of the provisions of the distribution

In the SUV salon, UAZ Patriot has an extra lever located near the gear shift lever. Consider what denotes the provisions of this lever.

Since UAZ Patriot is directly related to the cohort of SUVs, it should assume the mandatory presence in the design of this car full drive system. The presence of 4 leading wheels allows UAZ Patriot to confidently overcome the most difficult obstacles to which off-road.

Our article will affect the structural features of the full drive of the Ulyanovsk SUV. Also consider how the system works and how to enable four-wheel drive.

Principle of operation of the full drive system

There is no doubt that four-wheel drive is a very nice bonus for the owner of any car. Advantages in patency and stability on slippery coverage here on face. However, such a drive can present the owner of UAZ Patriot some unpleasant moments. The first of these is an increase in fuel consumption.

Let's talk about the advantages, since they are significantly more compared to negative aspects.

So, dignity:

the clutch with the road canvas is significantly rising;
confident start, especially on slippery surface;
much significantly improves;
more predicted handling and stability.

The disadvantages include the complexity of the structure, although it is a purely subjective aspect, because for most technically "savvy" owners a full drive UAZ patriot in a constructive plan does not seem something special.

Consider what types of all-wheel drive systems here are most common.

When the four-wheel drive is permanent.
With the possibility of manual connection.
Automatically connected.

In UAZ Patriot, the developers applied exactly the second type of system, that is, the all-wheel drive mode can be activated manually.

Such a scheme is endowed by a number of advantages, namely:

the ability to save fuel;
inclusion in the event of a need;
the cost of the nodes is significantly lower in comparison with the option where the four-wheel drive is connected in automatic mode.
It remains to find out how to enable four-wheel drive.

How does the device work? The main role in the All-wheel drive system UAZ patriot is assigned to Kardan, with which the rotation is transmitted to the rear wheels directly through the bridge of the stern. This is a mono-drive mode, because the front wheels are not yet connected and have the "status" of the slaves. Below will look at how to enable four-wheel drive.

Note that for energy-free SUVs such a design approach is the best solution. Here, the level of the distribution of the moment between the axes is 50 to 50 (as a percentage).

Drive operation for 2 axes is carried out by the kinematic scheme below.

Torque from the flywheel of the motor is sent to the gearbox, and it is transmitted with a distribution.
There is a special mechanism in the transfer box - the inter-axis differential. It is necessary to redistribute torque between axes.
When the front drive activation lever is turned off, then the transmission of the moment is carried out only on the rear axle.
If the lever is turned on, then the transfer box will start to distribute the moment already between the two axes.
As noted, the rotation force is transmitted to the cardan shafts, not only the rear, but also the front drive.
In order to activate the rear wheels, the designers installed the bridge, which consists of a gearbox with differential and semi-axes with hubs. Approximately similar nodes are applied and to transfer torque to the front wheels.
The useful properties of the system is the presence of a differential lock. This feature allows you to increase the permeability, as it synchronizes the rotation of the wheels on the same axis when slipping, and this does not lead to a significant loss of the moment.

The only disadvantage of the option appears that the system is not recommended to use for a long time, otherwise it is possible to quickly appear noise, vibrations and other symptoms of faults in the drive nodes.

Now let's talk how to enable four-wheel drive in the UAZ Patriot car.

Turning on the full drive on the patriot

The system management involves pre-switching the hub couplif. For the owner of the UAZ Patriot can provide the correct connection of the front axis drive, a number of uncomplicated manipulations will be required. So, the inclusion of the front bridge occurs as follows:

First manually activate the wheel clutches. For this purpose, from the side of the left wheel, we translate the pointer to the right, and from the right side to the left.
Now the previously specified lever includes a transfer box. The drive is connected - you can move.
This turns on the front axle.

If you want to activate the reduced gear, then we switch the dispersion lever to the corresponding position. This mode is necessary to increase the maintenance of the SUV. As you can see, the turning on the front axle does not cause any difficulty.

If you need to disconnect the all-wheel drive mode, we enter in the reverse order, that is, first return to the original position of the lever, and then turn off both couplings (hubs).

The positions of the rope lever and their meanings

The lever is located, of course, in the cabin in close proximity to the main lever of the transmission gear.
Let us turn to the consideration of the lever provisions with explanations, and how the device works.

The lever is located on the left behind. This position is the main and indicates a deactivated front drive. Here, the dispensing box does not function, and the transfer of the moment is fully addressed to the rear axle.
The lever moved forward and right. This position indicates the connected drive front. Note that the reduced transmission still remains inactive. This mode is very effective on slippery coating or when overcoming light off-road.
The position when the lever is translated to the right, and then back to half the initial stroke. This position is characterized by the neutral position of the dispensing unit, which indicates the fixedness of the car at a given moment.
The lever is in a position that almost corresponds to the previous one, however, is brought back to the stop. With such a position, the "observer" understands that the SUV operates according to the all-wheel drive scheme, and with activated reduced transmission. Such actions should be resorted while overcoming significant obstacles to off-road or if the UAZ Patriot "sat down" in the swamp and you need to get out from there. That is, the mode is effective in critical situations and continuous use is not subject to, otherwise the risk of harm to the system aggregates arises.

Let's summarize

In 2015, the manufacturer of Ulyanovsk SUVs made adjustments to the full drive system. Now connect the front wheels, that is, the management of the dispensing unit is carried out not using the lever, as we just considered, but by means of electronics. In the cabin, the traditional lever was replaced by a small regulator, which possesses similar functional. In the event that there is no lever in your car, then the turning on the front bridge occurs according to the scheme described

Bridges UAZ Patriot device, frontal bridge UAZ Patriot.

Bridges UAZ Patriot Their device and service are a fairly fascinating theme in the Wednesday environment. In particular, many worries front Axle UAZ Patriot, because constructive front axle harder in repair and device. Now we will tell about the bridges of the modern patriot more.

Modern Bridges Patriot type "Spyser" At the moment, they go with an increased to 1600 mm of Kolay. After all, old bridges had only 1445 mm and did not fit for a fairly wide patriot. Also in the design changed Carter the main transferwhich is closed by a removable metal cover, and to access the main transmission and differential now you do not need to remove and disassemble bridge, You can simply remove the lid.

The device of the front and rear axle "Spyser" is similar, and we will talk about the features just below. So Carter Bridge
consists of an indefinite cast Carter the main transferPassed in it housings (stockings) of the semi-axle and stamped cover. The lack of connectivity in the transverse plane of the bridge gives the design high rigidity (continuous type of bridge). Accommodation the main transfer and differential in a single crankcase provides durability and high accuracy of the gear of the main pair.

Front axle UAZ Patriot

Schematic front bridge Patriot is depicted in the first picture at the very top of the article. The main feature of the bridge can be considered the presence of shruses. After all, the front wheels besides the rotation, the proper and turn around. Initially, Weiss type shoes were used, but they refused them. Due to the design features, the angle of rotation did not exceed 27 degrees, which affected the car maneuverability. Therefore, new "Birfield" types are now installed, which provide a rotation of 32 degrees and more durable, due to a more uniform load on the elements of the rotary hinge.
