On the considered models one-disk dry coupling with a diaphragm spring is established. Coupling at inclusion of transfers separates power communication between the engine and the check point and provides thanks to frictional communication smooth torque transmission on a running gear at start-off from the place.
Coupling consists of a basket with a press disk, the conducted disk, the bearing of switching off of coupling with the hydraulic drive.
The basket of coupling is connected with a flywheel bolt connections. The flywheel is in turn connected with a bent shaft of the engine. Between a press disk and a flywheel there is a conducted disk which nestles on a flywheel a diaphragm spring of a press disk. The conducted disk is connected with a main shaft of the check point through shlitsevy connection.
By pressing a pedal of coupling via the main cylinder to coupling pedals liquid under pressure is transferred to the working cylinder. The piston of the working cylinder, pressing the coupling switching off bearing, the disk influences on press. At the same time the conducted disk is taken away from a flywheel. Power communication between the engine and the check point is interrupted.
The hydraulic system of coupling uses the brake fluid arriving from the tank, the general with the brake system.
At each inclusion and switching off of coupling power influence is resulted by wear of frictional overlays of the conducted disk. The conducted disk represents a high-wear part. However the average term of its service makes more
150 000 km. Wear of a disk depends generally on loading and style of driving. In particular, start-off from the place when coupling slips a long time, or the movement in mountains with the trailer leads to coupling combustion. Coupling does not demand service as it self-established.
