On considered models one-disk dry coupling with диафрагменной a 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 twisting moment on a running gear at трогании from a place.

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

The coupling basket is connected with a flywheel болтовыми 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 диафрагменной a spring of a press disk. The conducted disk is connected with primary shaft of a check point through шлицевое connection.

By pressing of a pedal of coupling through the main cylinder the liquid under pressure is transferred to pedals of coupling in the working cylinder. The piston of the working cylinder, pressing the bearing of deenergizing 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 coupling hydrosystem works on the brake liquid arriving from the tank, the general with brake system.

At each inclusion and deenergizing of coupling as a result of power influence there is a deterioration of frictional overlays of a conducted disk. The conducted disk represents быстроизнашивающуюся a detail. However average term of its service makes more

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