6. Coupling

6.1. Technical characteristic


Coupling is intended for short-term separation of the engine and transmission at gear shifting or braking and their smooth connection at start-off of the car from the place, and also for protection of details of transmission from dynamic loadings.

Coupling is one-disk, dry, constantly closed type, with the central press spring and a quencher of tortional fluctuations on the conducted disk. In a case of the transmission the main shaft of the transmission on which the release bearing which is not demanding maintenance settles down acts, and outside of a case the lever of switching off of coupling to which the coupling cable fastens is located.

The principle of action of coupling is based on torque transmission from a flywheel and the leading part of coupling on the conducted disk, so, and on a main shaft of the transmission, at the expense of friction forces which arise between disks at the included coupling. Due to elasticity of a press spring press the disk clamps in this situation among themselves and a flywheel the conducted disk with the effort which is not allowing its pro-slipping. At the same time the release bearing and a press spring do not adjoin.

By pressing a coupling pedal through a cable of coupling and a fork the release bearing presses a press spring of a drive plate of coupling and wrings out a drive plate from a flywheel therefore the conducted disk is released and torque transmission between the engine and the transmission stops.

Adjustment of a free wheeling – automatic also happens by means of the ratchet mechanism located about a coupling pedal.
