9. Coupling
Coupling
1 – clutch plate,
2 – leading part of coupling with a press disk, 3 – bolt, 4 – release bearing, |
5 – coupling switching off lever, 6 – the directing plug, 7 – coupling switching off fork, 8 – protective plate |
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 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 a release disk from a clutch plate. It is reached by use of the hummock drive. The fork of switching off of coupling moves the release bearing which influences a spring of a release disk and takes away press a disk from a clutch plate. Such design of coupling allows to replace a clutch plate, the release bearing and a sealing ring of the directing plug without removal of the engine or the transmission from the car.
