The principle of operation of the clutch

The clutch is located in the disc mechanism of the engine. It consists of pressure and drive discs.

A rotating clutch release shaft is located in the gear housing. It is connected to a decoupling bearing. Outside the casing, a release lever is mounted on the shaft, which is hydraulically actuated in diesel vehicles.

In the coupled state, by means of membrane springs, the drive disk is pressed from the pressure disk to the flywheel, and thus there is a rigid kinematic connection between the cardan and transmission shafts. The release bearing and release ring remain in place.

Clutch clearance adjustment is not required for hydraulically actuated clutches.

When the clutch pedal is depressed hydraulically via the clutch release shaft, the release bearing overcomes the force of the diaphragm springs and the pressure plate rises slightly. The clutch disc between the pressure plate and the flywheel is released, and the kinematic connection between the engine and the transmission mechanism is terminated.
