7.1. Coupling

7.1.1. Introduction


Coupling consists of a disk of coupling, a leading part of coupling with a press disk and the mechanism of switching off of coupling.

The disk of coupling is established between a flywheel and a press disk of coupling and moves on shlitsa of primary shaft of a transmission.

The leading knot of coupling is screwed by bolts on a flywheel. The torque at operation of the engine is transferred from a cranked shaft through a flywheel and a disk of coupling which is clamped between a flywheel and a press disk to primary shaft of a transmission.

To disconnect the engine from a transmission, it is necessary to take away press a disk from a coupling disk. It is reached by use of a hydraulic drive which consists of the main cylinder, the working cylinder of coupling and hoses. The pressing of a pedal of coupling moves the piston in the main cylinder and compresses liquid which on шлагу moves to the working cylinder. Under pressure the piston of the working cylinder moves and puts in action a fork of switching off of coupling. The fork of switching off of coupling moves tightening the bearing which influences a spring of a vyzhimny disk and takes away vyzhimny a disk from a coupling disk. Adjustment of coupling occurs automatically.
