On considered models one-disk dry coupling with a diafragmenny spring is established. Coupling at inclusion of transfers separates power communication between the engine and a check point and provides thanks to frictional communication smooth transfer of a torque on a running gear at a troganiye from a place.

Coupling consists of a basket with the press disk, a conducted disk, the bearing of switching off of coupling with a hydraulic drive.

The basket of coupling is connected with a flywheel boltovy connections. The flywheel is in turn connected with cranked shaft of the engine. Between a press disk and a flywheel there is a conducted disk which nestles on a flywheel a diafragmenny spring of a press disk. The conducted disk is connected with primary shaft of a check point through shlitsevy connection.

By pressing of a pedal of coupling via the main cylinder on coupling pedals liquid under pressure is transferred in the working cylinder. The piston of the working cylinder, pressing the bearing of switching off of coupling, the disk influences on press. Thus conducted disk is taken away from a flywheel. Power communication between the engine and a check point interrupts.

The hydrosystem of coupling works at the brake liquid arriving from the tank, the general with brake system.

At each inclusion and coupling switching off as a result of power influence there is a wear of frictional overlays of a conducted disk. The conducted disk represents a fast-wearing-out detail. However average term of its service makes more

150 000 km. Wear of a disk depends generally on loading and style of driving. In particular, the troganiye from a place when the long time slips coupling, or movement in mountains with the trailer leads to coupling combustion. Coupling does not demand service, as it being self-established.
