General description (Audi 80 B4)

The transmission of torque from the engine to the gearbox is carried out due to the friction forces that arise between the surfaces of the flywheel and the pressure plate, between which the driven disk is located. The clutch is released, which is performed as the pressure plate is moved away from the driven disk, through a hydraulic drive controlled by the clutch pedal. The force from the pedal is transmitted to the clutch release fork, and from it to the clutch release bearing (release bearing). When you press the clutch pedal, the piston of the master cylinder of the clutch release drive squeezes out a certain amount of fluid and drives it to the slave cylinder of the clutch, located on the gearbox. The piston of this cylinder then extends and acts on the clutch release fork (see illustration 1.0).



Each time the clutch pedal is pressed, the friction linings of the driven disk come into contact with the opposite surfaces and, as a result of friction, heat up and wear out. The greatest wear out occurs when starting off at a high engine speed, starting off in 2nd gear and in cases where the driver does not remove his foot from the clutch pedal while driving.
