The transmission is the most mysterious unit in the car, especially for drivers who are weakly tard in technical terms. It seems that everything is simple - squeeze the clutch, push the lever and the car goes. But, if something happens to the gearbox, for example, the rear transmission does not turn on, then involuntarily start to regret that the checkpoint in the car is not automatic, but mechanical. Although automatic aggregates are also not deprived of these problems.

Gearbox, device

The task of the mechanical gearbox is the change in torque and its transmission from the motor to the wheels. It is capable of an unlimited period to ensure the separation of the power unit and leading wheels. Consider what elements are included in the design of the MCPP:

1. Carter.
   
2. Primary, intermediate and secondary shafts with gears.
   
3. Additional shaft.
4. Reversing gears.
   
5. Synchronizers.
   
6. Transmission mechanism with locking and locking devices.
7. Switching lever.

The crank contains the main nodes and gearbox elements. Carter PPC is connected to the clutch crankcase, which is attached to the engine. Since in the process of the gear gear, the gearbox is subjected to serious loads, they need good lubrication. Therefore, the carter is half off with transmission oil.

Synchronizers are needed for unstressed, silent and smooth transmission, by adjusting the angular velocities of the spinning gears.

PCP shafts rotate in the bearings mounted in the crankcase, and also have gear groups with different amounts of teeth.

The gear shift mechanism is designed to change the speeds in the box and is controlled by the driver with the lever from the car's cabin. The locking device, at the same time, does not allow two transmissions to turn on simultaneously, and the locking device is designed to hold transfers from spontaneous shutdown.

Rear transmission, possible malfunctions

If the rear gear does not work, first of all should be sorted out how serious breakdown is. Remember how the gearbox behaved lately. If her work was normal and did not cause anything to be anxiety, it means there is hope that everything is not so bad - still the transmission unit is reliable and complex, with a huge margin of strength, therefore it does not break off at level while. The reasons why rear gear does not turn on may be several. Consider them in more detail.

Sleeve of the Kulisa, if the sleeve was worn out, how to fix

The wrenches of the sleeves of the scene can indicate a certain lever breaking. Although if its wear proceeds evenly, that is, it goes with his guy, the driver can get used to the free move of the scenes, as a result of which not to notice the approaching problems. The situation is solved by replacing the sleeve - remove the cover of the lever, after which we dismantle the Kulisa itself. Then we change the plastic sleeve on the previously purchased and install everything in place. This event is made in the car's cabin.

Electrical part, possible malfunctions, how to eliminate

In some models of vehicles, when the rear velocity is turned on, electromagnetic lock is used. At the same time, the wires are simply dangling under the bottom of the car. In our conditions, this is an unforgivable negligence, since the wires are damaged or rot. As a result - no connection, resulting in problems with speed switching.

Traction gearbox, if the car is outdoor traction gearbox, to pay attention to

In some models of the car location, the box implies the use of outdoor speed switching. With bad weather conditions - when icing, sticking snow or dirt, their free move is sometimes difficult, especially this refers to the rear gear, since it is not often used, and in the morning turn on the first thing.

PPP oil, how to check the oil level, how to replace oil, why you need to check the gearbox and shaft glands

If the vehicle is not new, it is impossible to know when the last time the oil changed in the gearbox and whether it changed at all. You can check its level using a special probe. In addition, pay attention to the shaft glands and gearbox gasket. If they wear out, a transmission oil leak may occur. But that the worst, the driver may not notice, as with time, dropped a day, from the box the entire lubricant. The gearbox to this problem reacts with increased noise, however, as practice shows, it can also be noticed. The replacement of oil, as well as replacing the glands and gaskets, is better to produce a hundred, however, if you are an experienced driver and have certain knowledge in this area, you can replace these items yourself.

Remost of refinement bearing, springs, gears, forks - signs of wear and who should make the repair of the checkpoint

All data breakdowns are usually accompanied by outsiders in the course of work, do not pay attention to which is actually impossible. Repair will require the removal of the gearbox and participation of specialists. Your task is not to tighten with a trip to a hundred. This will help you save money and may prevent irreversible destruction.

Tips Pros: Qualitative and timely care for the checkpoint, the key to extend the life of the car

To extend the service life of the car and the gearbox in particular, it is necessary to take time timely and efficiently for it. The systematic replacement of oil, the glands and gaskets is a mandatory event, and when at least the slightest signs of the gearbox malfunction should be immediately referred to professionals, in order to avoid more serious problems.
