General information

Coupling consists of a frictional (conducted) disk, basket assembly with a press disk, the vyzhimny bearing and the mechanism of switching off of coupling. All components are placed in a big case from the aluminum alloy, sometimes called by a dome of coupling/transmission and established between engine and transmission blocks. Switching off of coupling is made mechanically, by means of a hummock drive.

The frictional disk is established between a flywheel of the engine and a press disk of assembly of coupling and freely moves lengthways шлицов primary shaft of a transmission.

Assembly of a basket of coupling приболчена to a flywheel. At the working engine and the released pedal of coupling rotation of a cranked shaft is transferred through a flywheel to a frictional disk of coupling (the last densely nestles on a flywheel assembly of a press disk). As the frictional disk of coupling is planted on a shlitsa of a pin of primary shaft, the last provides rotation transfer to a transmission and, further on driving wheels of the car.

It is necessary to make coupling switching off for the termination of rotation of a transmission. On models of cars described in the real Management two various designs of the mechanism of switching off of coupling are realized. In the first case the mechanism of usual type with the independent vyzhimny bearing which has been put on a pin of primary shaft of a transmission is applied and at operation of a press disk of coupling nestling on a diafragmenny spring such mechanism is established on all cars of a model range, the exception is made by only diesel models with a turbo-supercharging and petrol models with the 16-klapanny engine of the RFY series where the mechanism of exhaust type is applied. In mechanisms of switching off of coupling of exhaust type the bearing is used built in assembly of a basket of coupling and standing separately from a frictional disk vyzhimny.

In mechanisms of usual vyzhimny type the cover of a driving cable from a transmission is closed up in a basic arm, the core is connected to the lever of a fork of switching off of coupling. When squeezing a pedal of coupling the core of a cable is delayed, developing thus for the top end of the lever a switching off fork. A fork, being developed, presses vyzhimny the bearing to petals of a diafragmenny spring of a press disk. The spring is thus deformed, weakening a clip of a frictional disk to a flywheel.

On models with the exhaust mechanism of switching off of coupling in an arm on transmission the cable core whereas its cover is connected to the lever of a fork is fixed, on the contrary. When squeezing pedal the fork of switching off forces to rise on vyzhimny the bearing fixed on a diafragmenny spring of a press disk. Deformation of a spring leads to an otpuskaniye of a frictional disk which departs from a flywheel, stopping transfer of rotation of the engine to primary shaft of a transmission.

Correctness of its adjustment gives a guarantee of serviceability of functioning of coupling.
