11.2. General information


Coupling
 
1 – flywheel;
2 – clutch plate;
3 – press disk;
4 – bolts;
5 – press bearing;
6 – coupling switching off fork;
7 – a hairpin with a spherical tip;
8 – protective cover

Coupling is intended for short-term separate a niya of the engine and transmission at gear shifting and braking and their smooth connection at start-off of an avtomoba of la from the place, and also for protection of details of transmission from dynamic loadings.

The torque from the transmission on wheels is transmitted through power shafts which consist of two hinges of equal angular speeds and a shaft.

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

The clutch plate is established between a flywheel and a press clutch plate and moves on vents of a main shaft of the transmission.

The leading knot of coupling is screwed by bolts on a flywheel. The torque during the operation of the engine is transmitted from a bent shaft through a flywheel and a clutch plate which is clamped between a flywheel and a press disk to a main shaft of the transmission.

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