What is the difference between mechanical gearboxes on Lada Xray. Mechanical transmission transmission box, MCPP KPP Lada Ix Rei

27.08.2020

We understand the features of the mechanical KP Alliance Renault-Nissan for the new Russian compact crossover.

Today is the future owners Lada. Xray Offers to purchase a car in two versions: a foreign kit with an engine from the Renault-Nissan H4M Alliance (1.6 l. 110 hp) and a French manual transmission JH3, Russian version with a new engine 21179 (1.8 liters 122 hp. ) Production of OJSC AvtoVAZ and automated mechanical transmission LADA. A little later official dealers The symbiosis of our engine 21129 (1.6 liters 106 hp) and a foreign box of the JR5 of the Renault-Nissan Alliance, which is already applied to lada cars Vesta.

Total moments

In this material, we consider the differences in the mechanical gearboxes of JH3 and JR5, which are provided for a new compact crossover. Both transmissions are largely the same by design, but differ in clutch shutdown nodes, gear ratios in the box, gear shift mechanisms and comfort for passengers. Both alone and the other gearbox for XRAY are made on a two-way diagram, and have synchronizers of all front motion gears, which are combined with differential and main transmission. For the first and second gear, a 3-cone synchronizer is used. For the third, fourth and fifth, conventional synchronizers are used. All boxes have a "fool" protection and block the inclusion rear transmission During the move forward. In both boxes, transmission oil is poured on production, the service life of which is equal to the service life of the entire car. Therefore, his replacement is planned maintenance Car is not produced.

Visual differences

The JHZ gearbox clutch node represents the cable switching connected to the clutch pedal. JR5 gearbox clutch node is a hydraulic working cylinder. The working cylinder is connected by the main cylinder pipeline, the clutch pedal is affected by the rod. Manage jNZ gearbox with hard thrust, and JR5 gearbox with two flexible cables. As a result, the inclusion of gears of the box intended for the Russian motor will be more comfortable than it is made from the checkpoint for the Alliance motor. This will be especially noticeable to affect the principle of inclusion, which will be easier to be made and without inherent boxes with traction control. The advantage of the JH3 box will be disclosed only at high speeds. The greater the value of the gear ratios 3.4, 5 speeds allow the car to gain speed faster and, as a result, make overturns. In terms of maximum speed, this KP also wins the JR5 box for a Russian motor. Maximum speed With the Russian unit will be below 5 km / h. But the number of motor turns at the same speed in a pair with JR5 will be lower.

In terms of fuel consumption on passport data, Renault-Nissan H4M pair (1.6 l. 110 hp) and the French mechanical gearbox JH3 will be more economical than our engine 21129 (1.6 liters 106 hp) and foreign boxes JR5 Alliance Renault -Nissan. According to the data presented on the official LADA website, the consumption in the mixed cycle will be less than 0.5 liters, and on the highway by 0.3 liters. Differences in fuel consumption are not so great, and if the owner is important smaller vibration on the KP lever and more easy switching speeds, its choice will be a kit with a Russian motor and a French box. Another important factor will be the price for so. Accessories for the domestic unit are cheaper than similar details for a foreign fellow.

Lada Xray car in the country market for quite a long time. A lot of reviews have accumulated on the Internet, wishes and claims from the drivers of this car regarding the transmission. Recall that when designing this car The designers appeared before choosing: how to equip the transmission of the freight, except the version with the mechanics. There were two options: automatic gearbox and robotic transmission. The decision taken by AvtoVAZ was to choose the second option. After analyzing all the factors affecting the implementation of a box, the developers stopped at an option with a robot. Why? And what came out of it? Let's try to figure out.

Semi-automatic in Lada Ix Rei

After the concept of Lada Ix Rei, with a manual switching box, the question of the alternative to the mechanics remained open and very interested in potential consumers. The need to develop a box option except mechanical gearboxwas unconditional. This is especially true for residents of megacities that are dealing with such a phenomenon as a day. Shift velocities manually using the lever in this driving mode - is not physically very convenient.

Drivers won, what automatic will be at the Xi Rey, and they were the semi-automatic AMT (auto- mechanical transmission). During the time who passed from the presentation of the Lada at the exhibition before launching it into mass production, AvtoVAZ decided to introduce as a second transmission version a semi-automatic robotic box. This species The transmission is a five-speed box, on the principle of operation similar to the manual gearbox, in which the switching function and inclusion of the clutch with an expensive is carried out by an electronic control system (because of this it is customary with a robot).

Lada Ix Ray Box has been developed on the 5-stage platform from the VAZ 2180 and has similar specifications. Moreover, the main mechanism of this PPC was not replaced, but only improved together with german concern "Fritrichshafen".

The reasons for the choice of tolyattins in favor of the robot

Robotic checkpoint at one time made a jump in the progress of world autoinadustry. However, the experience of applying this development by many foreign companies, as some kind of know-how, was not always obtained unequivocal. In theory, this is a transmission option that is designed to create a stubborn competition of automation by demand among consumers. But in reality, during the long-term practice of introducing this alternative, even the eminent European concerns were not quite successful cases of the release of cars with semi-automatic.

There are many reasons for and against the choice of such a transmission. And when choosing optimal optionwhich system is an alternative mechanic, automobile plants Comparish many factors in favor of a particular box. The robot has its advantages and disadvantages. In the case of AvtoVAZ to introduce the semi-automatic CAT, the following reasons were.

The production of the robot is less expensive compared to the machine.
The prototype to create a robot was a mechanic from VAZ.
In one car, manual and automatic switching are combined, which attracts more consumers.

Regarding the first advantage from the list, it can be noted that when using it, the manufacturer significantly reduces the cost of manufacturing a car. At the expense of this AvtoVAZ was able to offer a competitive price on the market.

If X Rey was started with automatic transmission ( automatic box Switching gear), then with confidence it can be argued that the car would cost 50-100 thousand rubles more expensive.

The factant that the robot is designed on the VAZ platform is even more profitable for the formation of a relatively low price. The third plus of Xu is said above, attracts both automotive lovers and hand-made adherents. This advantage, in addition to simplifying pricing, makes the XRAY model even more successful in terms of demand and marketing in general.

Specifications and prices of complete sets with different boxes

Lada Ix Rei is for sale in various options for complete sets. The cost of Lada depends on these variations. The most budgetary version of X Rei with base facility You can purchase at a price of 590 thousand rubles. The most equipped hatchback has a cost of just over 720 thousand rubles.

The creators of this model have developed various types of engines for different transmissions options. The five-speed mechanic is produced in combination with the domestic unit, the volume of which is 1.6 l, and the number horse power Under the hood - only 106. Also in a pair with a manual gearbox, a Japanese sample engine with a similar volume can be equipped, but the power of which is slightly more - 110 liters. from.

AMT is combined with only one type of motor. The aggregate is more voluminous - 1.8 liters. With an increase in the size of the cylinders, the magnitude of the car was added. It is 122 horsepower.

We understand the features of the mechanical KP Alliance Renault-Nissan for the new Russian Lada Xray car.

Today, the future owners of Lada Xray are offered to purchase a car in two versions: a foreign kit with an engine from the Renault-Nissan H4M Alliance (1.6 l. 110 hp) and the French manual transmission JH3, Russian version with a new engine 21179 (1.8 liters 122 LS) produced by OJSC AvtoVAZ and automated mechanical transmission LADA. A little later, official dealers will have symbiosis of our engine 21129 (1.6 l. 106 hp) and the foreign box of the JR5 Renault-Nissan Alliance, which is already applied on Lada Vesta cars.

For the first and second gear, a 3-cone synchronizer is used. For the third, fourth and fifth, conventional synchronizers are used. All boxes have the protection of "fool" and block the inclusion of the reverse gear during the move forward. In both boxes, transmission oil is poured on production, the service life of which is equal to the service life of the entire car. Therefore, its replacement for scheduled maintenance of the car is not produced.

The JHZ gearbox clutch node represents the cable switching connected to the clutch pedal. JR5 gearbox clutch node is a hydraulic working cylinder. The working cylinder is connected by the main cylinder pipeline, the clutch pedal is affected by the rod. Manage jNZ gearbox with hard thrust, and JR5 gearbox with two flexible cables.

In terms of maximum speed, this KP also wins the JR5 box for a Russian motor. The maximum speed with the Russian aggregate will be below 5 km / h. But the number of motor turns at the same speed in a pair with JR5 will be lower.

In July, there were no vaza boxes in chrona yet.
There are also burocks in imported boxes ...
I did not lose and drove today to replace the six-fifth gears. The master told that the repairs of rosy boxes, including complex ones.
I drove my typewriter on the lift, removed the wheel and got access to the lid of the fifth gear:

Removed the lid, saw the gears:

They are not very simple, special puller are used. And in time not fast. On my question - why not warming, the master replied - only Armenians warm
As a result, everyone was done about two hours with small breaks. ELF oil 75W / 80, poured on-1 when running 15450 (now 25200) clean, like a tear. His poured back. In Litrushka, just in case, 700 grams left after the replacement, approximately 100 of them were useful for a tank (a little shed during disassembly).
Now about impressions. At a speed of 105 km / h made pictures of tidy 1. BE and 2. After:
1. 2.
It is not very convenient to photos on the go, but the difference in turnover turned out at such a speed of about 300 rpm. Maybe a little more. It is a pity that I removed the multitronix, otherwise in numbers (and not by the arrow) it would be more accurate.
A few more photos for which you can compare the turnover with your:

While drove only 60 km after the replacement, therefore the data is not enough. But the fat plus replacement is already clear - at a speed of 120 km / h, he stopped manifesting a strong hum. There is no it at 130 km / h, and at 140. no longer accelerated. Silence in the cabin is unusual, but very pleasant.
Still misled himself
Before departure to the service station, I dropped the testimony of the staff of the BC, on arrival I saw the consumption of 8.6 liters. Of course, the route was on the M5 Ural, which now on my segment is in perfect condition. Well winter wheels Promote an increase in flow. Before returning home, I reset the BC again, and on arrival discovered consumption 8.0. At the same time, a gaze led more seriously, in order to experience new gears. I thought .... can't fall so sharply, it does not happen miracles. And only half an hour later I remembered that I was driving on the service on gasoline AI 92 networks, and in front of the expensive back 30 liters of the same 92, but the network L. everything fell into place in its place, everything is fine with consumption and miracles do not really.
In the course of further operation, I will watch the flow rate, but I do not expect any special changes.
About elasticity. 55 km / h Now, of course, you will not turn on the fifth. There is a reasonable minimum - 70 km / h, and better 80. By the way, the prompt with somehow adapted and now lights up the green arrow up at a speed of 75 km / h. The fourth will now have to join more often, but this is the best - overtaking will occur with a margin. In the presence of a cruise, such a fifth only in plus and in joy.

Modern gearboxes are used in the new Lady X Rey, the development of which was carried out specifically under this model. Presented to the checkpoint are the next step for AvtoVAZ cars. They are deserved about them positive reviews Among motorists who have experienced them in action.

For Xray, there are three options for the checkpoint, of which two were developed by the French, and the third AvtoVAZ themselves. The first two options have a five-speed mechanical switching of speeds, and the domestic box robotic automatic. Domestic AMT Transmission quickly showed itself as the most reliable and high-quality among this type CAT. When using it, the driver can quickly switch between mechanical and automatic modes.

Transfers are divided into the following options:

MCPP JR5 518 - French 5-speed, using a multiconus synchronizer;
MCPP JH3 512 - French 5-speed PPC;
robot VAZ-21827 - robotic box AvtoVAZ.

Mechanical box The gears Xpete is divided into two options: JR5518 and JR3512. Although they both have 5 stages of gears, but differ in the clarity of switching and reliability of the transmission as a whole. Unlike old gearboxes used by the manufacturer, new work is significantly quieter and more vibrate. The switching lever stroke has gained smoothness and ease of course, which reduces the accompanying effort while driving.

The gear shift module for X Rey, which is responsible for the smoothness of switching was produced in Germany. Silent and strength box betray the secondary shaft and new synchronizers.

Robotic checkpoint in Xray

According to strategic reasons, AvtoVAZ decided to replace normal automatic Ri to a robotic gearbox. Initially, this checkpoint was not accepted by motorists, but after some time she was able to get an excellent reputation, showing its advantages in practice. She was able to bypass the quality of the fulfillment of foreign analogue.

Robotic checkpoint has built-in electrical components that compensate for the clutch operation. The clutch itself was produced by Valeo, and the actuators come from Germany. In the box there is a protection that prevents incorrect switching. PPC has low fuel and oil consumption. It uses both manual and automatic mode, as well as a reset mode. Shift shift occur quickly and without twitching.

The automatic gearbox in XRay is able to independently adjust the way of driving the owner, and does not require warming up even with severe frosts. In general, the reviews of the owners are positive, but there are questions on her work. For example, the need to fix the press of the gas pedal or during stopping is not a camping. In some cases there may be easy twitching of the checkpoint.

Watch the video test drive with an AMT gearbox from fox:

Some owners Lada Xray. With a cable gearbox (MCPP 2181), they encountered an annoying warning from it. This deficiency of Xray got a great resonance. It is trying to get rid of this problem with a fundamental way, establishing an alternative transmission - "Robot" (AMT 2182), which is also not perfect ...

Automated transmission Lada. Xray is based on a serial manual transmission MCPP-2180. The development of the machine was carried out in conjunction with the German company ZF. Actuators of switching speed and clutch switching actuators were installed on the Lada Xray gearbox, as well as modern software. The peak of the level of transmission noise in the cabin at 1500-3500 rpm decreased from 55 to 35 dB.

Alas, an extraneous sound can still appear on 1 and 2 transmissions when the turnover is approaching 2000 rpm.

Therefore, if you have noticed a barely audible howl to AMT, you should not be upset ahead of time. In some cases, he leaves after running, or after replacing transmission Oil. Solution - noise insulation of the floor of the car. In any case, the main mass of motorists of howling AMT does not bother.

Unfortunately, the noise of AMT is not the biggest drawback. Read more ...

For example, when switching gears, shocks appear, jerks or during the work, extraneous sounds (howl, hum, cracking, etc.) are heard.

Consider the instructions for determining AMT faults.

The verification procedure is described in the book on the operation, repair and maintenance of the car Lada Vesta:

1. We are convinced of the performance of the AMT control system, for this, we include ignition. Then, by pressing the brake pedal, we move the selector lever in turn to all the positions, while the appropriate characters should be displayed on the instrument panel. After that, we return the selector lever to the N ("neutral" position).

2. Run the engine. If from the clutch crankcase angle sound is heard probably worn released Bearing clutch. A similar sound can be caused by the wear of the gear bearings.

3. Holding the brake pedal is pressed, we switch the selector in turn to all the provisions, while we are convinced of the gear shift mechanism. The inclusion should be light, without a cod and crunch.

Comment:

If when you turn on the clutch current sound is amplified - Worn out the release bearing clutch. If the sound disappears, the gearbox bearings are worn.
If when the transfer is turned on cracks , car twitch So the clutch is not completely turned off. The reason may be a malfunction of the gear shift mechanism, wear or loss of elasticity of the diaphragm spring spring, as well as the malfunction of the clutch shutdown. To check the gear shift mechanism and the clutch shutdown electric drive, you must check the fault codes stored in the transmission control unit, so such work should be performed on a specialized station with the necessary equipment.

4. Set the selector lever to the N ("neutral" position). Lower the brake pedal, while the car should not start moving.

5. Check the lada xray gearbox operation in motion. To do this, we turn on the mode A (forward in automatic mode) and slowly press the gas pedal. In this case, the grip must be seamlessly engaged. Moving first with acceleration, and then with a slowdown, we are convinced of the smoothness of the clutch inclusion, in a smooth switching of gear (both in the direction of increasing and downward), in the absence of crunch, knocks and other outsided sounds Gearbox.

6. Turn on M mode and repeat the check, switching transmissions in manual mode. For this, moving the selector lever first towards the "+" symbol, and then "─". The box should work without failures, switching transmissions in the selected direction.

7. Stop the car and translate the selector lever to R. After letting the brake pedal, the car should start moving back.

Comment:

Rod and Daressg At the time of switching on the clutch, it can be caused by grinding or a junction of clutch discs or the destruction of the vibration damper.
Undime gear either enabling the transmission of non-corresponding movement speed caused by a malfunction of the transmission control unit.
Rod and delays when switching gear during the movement of the car, enabling shifting may indicate a malfunction of the gear shift mechanism or the clutch shutdown electric drive. The elimination of such problems is due to the need to read the fault codes stored in the transmission control unit, so such work should be performed on a specialized station with the necessary equipment. In addition, when replacing a faulty mechanism of the electric drive, you must configure the transmission control system. Otherwise, the correct work will be impossible.

Recommendations: If there is no possibility to restore the performance of the gear shift mechanism or the clutch shutdown electric drive (for example, due to the lack of spare parts), then AMT can be converted to manual control. To do this, dismantle the specified parts and set the shift mechanism with a cable drive, as well as the clutch shutdown cable.

8. When moving on the third or fourth gear, we sharply press the gas pedal. If the turnover increases quickly, and the car accelerates sluggishly, then the clutch is slipping.

Comment:

The adhesive wear can also be evidenced by the appearance of Gary's smell in the salon, which issued strongly heated friction linings of the slave disk. In this case, it is necessary to replace the clutch.

9. We inspect the transmission from all sides on the overpack, we are convinced of the absence of transmission oil leaks.

Comment:

There are more and more connoisseurs of two-winning machines every day. No wonder that automotive concerns Go to installation automatic transmissions not only on expensive but also budget models. AvtoVAZ also does not intend to lag behind global trends, as a result of which a series of its cars is already equipped with automatic transmission. The release of the new hatchback Lada Ix Ray himself implied the presence of a version with an automated box. What did IS RAY have made potential buyers?

Lada Xray - automatic transmission or amont?

The solution to this issue was extremely important for the company, because the domestic manufacturer intended to create a modern, technological and relatively inexpensive car. It was from the budget considerations that the option of hatchback was discarded with a classic 5-range "automatic", as it would noticeably affected the price of Lada Ix Ray. Of course, there was an option for equipping it with a 4-speed hydrotransformer from the Japanese concern Jatco, but the installation of just a 4-range box was recognized as meaningless, since it is a model image, as a technological car, would immediately die.

As a result, a compromise solution was found - 5-range, robotic transmission of type AMT series VAZ-21827.

Features of the design "Robot" Lada Iks Rey

The basis for this box was the mechanical transmission of the VAZ-2180 type. Its design has been upgraded, added the electronic unit Management, actuators supplied from Germany by ZF, clutch from Valeo and multicompute synchronizers. Oil in it is flooded for the entire service life, so its periodic replacement, as in a simple "automatic" or variator, is not provided.

Transmission numbers in such a gearbox are as follows:

I transmission - 3.636 units;

II transmission - 1.950 units;

III transmission - 1.357 units;

IV Pedaging - 0.941 units;

V Transmission - 0.784 units;

Main transmission - 3.938 units;

Rear gear - 3.500 units.

In general, the quality of the work of a robotic box is inferior to such a classic 5-range "automaton". The robot is stronger thanks in traffic jams, it does not respond as quickly to the Kick-Down commands and so on. In addition, on the convenience there is a need to put X Rey on parking brake When stopping on the rise. Nevertheless, he also has strengths:

Noise background is absent, as well as vibrations on the box lever.

The lack of need for warming up - while the usual automatic transmission has to warm up before driving, "robot" is without that. Even in the frost you can go immediately.

Towing auto and trailers - an extremely useful feature. After all, a simple "automatic" ride in this mode, as a rule, does not withstand. But for AMT Lada Ix Ray, towing is not terrible.

No need for maintenance.

There is a reset mode.

Acceptable fuel consumption with urban ride - 8.5 liters per hundred.

There is a lock from erroneous switching.

"Robot" also has a manual mode.

In general, all these advantages, along with a lower cost, quite justify the AvtoVAZ decision to save and make the price of the car slightly lower.

Reaction of motorists

Initially, many were skeptical, believing that a robotic box would not replace the classic "automatic". However, with the extent, all the advantages of the transmission were revealed, and the absence of breakdowns added points to Piggy Bank AMT. However, many believe that without a full "automaton" Lada Iks Ray will still be difficult to compete with other models.

The present video briefly describes the technical data of Lada Iks Ray. AMT box is also mentioned:
