Drive of management of coupling

Coupling and drive of management of coupling

1 – the conducted disk;
2 – press disk;
3 – release bearing;
4 – coupling switching off coupling lever;

5 – the directing plug of the release bearing;
6 – working cylinder of coupling;
7 – main cylinder of coupling;
8 – coupling pedal.

Force which we apply when pressing a coupling pedal has to be transferred to the release bearing. It occurs in Audi 80 hydraulically – as in the brake system. While you press on a coupling pedal, the piston in the main cylinder (on a coupling pedal) squeezes out a certain amount of liquid to the working cylinder (on the transmission). There the piston acts from the cylinder a little and via the lever of switching off of coupling sets the release bearing in motion.
