The power supply of the vehicle maintains the transmission of torque to the transmission, which corresponds to various crankshaft rev.. The gearbox also produces a change in torque to a smaller or most side by changing gear gear ratios. However, in order to engage the required gears, the gearbox must be disconnected from the power plant, in other words, so that the engagement occurred, the Primary PPC shaft should not take the rotation from the flywheel. For short-term disconnection of the CP from the power plant, a clutch is provided in the auto design. The task of this component is to temporarily disconnect the gearbox from the power unit to enter certain gear gears when the gear shifts. In addition, the clutch produces ensuring transmission of rotation at the time of the beginning of the movement from the spot. The adhesion action is based on the force of friction between the materials different in structure. The TS applied friction between the metallic components - pressure plate, the flywheel and the clutch, which are constructed as lining and disposed on the driven disc.

Coupling vehicle apparatus and operation

Car clutch consists of the drive and two drives - the master and slave.

The leading disk drive casing structure includes - a basket, by which it is attached to the flywheel. Inside the housing is a pressure plate, which is pressed against its surface to the drive plate, and more specifically, to its friction linings. This disc is able to move within the basket. Drive plate also consists of a spring which is compressed to the pressure plate friction linings.

To move the pressure plate inside the basket and thus remove it pressing against the drive plate, it is necessary to overcome the force of the springs. The cargo vehicle for this leverage applied. Cars have a slightly different design - here used the diaphragm spring, which is made in the form of an off cone with a truncated top. The spring is attached to the outer edge of the pressure plate. The cone itself protrudes slightly from the housing. In this cone is closer to the center of punched petals that act as levers. When data indentation petals inwardly cone able to flex inwardly and draw the basket pressure plate.

Clutch plate is a metal, with the two sides of which are riveted or bonded friction linings. At its center is the hub sleeve, which is movably connected with the steel part by the damper springs and friction washers. This splined hub it is mounted on the primary shaft of the transaxle.

In the exercise of connecting the internal combustion engine to gearbox, clutch disc when pressed to push the flywheel, the springs are compressed data, thereby providing a smooth turn.

Friction disc springs are needed in design to damp torsional vibrations.

Clutch - a clutch release bearing, clutch fork and leverage.

Everything works as follows. If the clutch pedal is released, the diaphragm spring, because it does not affect anything, presses the pressure plate toward the flywheel driven - the rotation is transmitted continuously.

When the driver squeezed the pedal force is transmitted to the plug by means of a system of levers. Fork presses on the release bearing, which is located on the primary gearbox shaft. Bearing moves along the shaft and presses the spring diaphragm type, which goes deep into the basket and puts pressure on the pressure plate, which, in turn, leaves, stops to draw in clutch disc, resulting in a rotation transmission stops, that is, the engine is disconnected from the checkpoint.

Fault automobile clutch, signs of possible malfunctions

The most common problems with the clutch:

1. "Slippage". This problem occurs if the clutch is not properly adjusted - free running virtually absent and the bearing presses on the diaphragm spring type. In this case, even if the pedal is fully released, the clutch all exactly remains a bit squeezed, which is accompanied by slip discs. If the problem persists, as a result of high temperature metal drive plate portion may bend to occur fast wear lining and possibly their destruction, they Pidgir'ya and fine cracks are formed on the flywheel.
   
2. Clutch "leads". This problem is also formed by maladjustment. However, it comes down to too much free movement. Coupling in this case pushes the pressure plate completely, the rotation is transmitted even if the pedal is squeezed as much as possible. This adversely affects the discs that can warp, crack or even withdraw from the PPC system.
   
3. Jerks when starting. Perhaps the demolition drive overlays, derailing damper springs seats. Besides, the disc hub may jam when moving and separating lobe diaphragm spring, whereby the pressure plate moves out of alignment.
   
4. Increased noise during operation indicates the failure of the release bearing.
   

Clutch replacement, in which cases you want to replace the clutch

The need for dismantling and replacing the clutch, as a rule, there is the appearance of the above-described fault - a lot of noise when operating the clutch, a large free play or lack of it, jerks when starting.

Safety and workspace

On VAZ cars to get to the clutch, it is necessary to dismantle the checkpoint. And because it is shot down, you'll need an observation pit. It is mandatory to observe the safety precautions in order to avoid problems.

Tools, fixtures, consumables

1. New clutch components.
2. Edit, which can be made from an old drive shaft.
3. Key sets.

How to remove the gearbox to get to the clutch, step by step instructions

We proceed to disassembly. From the Carter, disconnect the clutch cable, and from the checkpoint - traction lever gearbox. Next, remove the starter, and with the CP merge the oil.

Then we unscrew and remove the drive shafts. So that the gears do not shift in the box, at least on the one hand it is necessary to insert the old shrus.

Next, unscrew all the crankcase mount to the motor. In order for the PPC to remove, on the left side of the car remove the lower suspension levers.

Motor must be signed, as you have to unscrew the left and rear supports. Then maintaining the gearbox, between the power installation and the clutch crankcase, we drive the screwdriver and remove the clutch crankcase with the spills.

How to remove and put a clutch, step by step instructions

Before removing the basket insert a predetermined editing to the place of the primary shaft of the KP.

Next, unscrew the fastening bolts of the clutch basket, after which we remove the drive disk with the car.

Now remove the slave disk.

Then we visually evaluate the clutch elements. If you find at least minor damage to the adhesion parts, it is necessary to replace the clutch of the TC.

Installing a new clutch manufacture in reverse order.

Tips Profi on the use of pre-prepared edits so that there are no problems with the installation of the CAT in place

Do not forget to use editing. Without it, it will be impossible to conduct a center for the location of the slave disk, and in the future you may have problems with setting gearbox in place.
