The clutch is single-disk, dry, permanently closed type, with a central pressure spring and a torsional vibration damper on the driven disk. The gearbox input shaft protrudes into the gearbox housing, on which the release bearing is located, which does not require maintenance, and outside the gearbox there is a clutch release lever to which the clutch cable is attached.
The principle of operation of the clutch is based on the transfer of torque from the flywheel and the leading part of the clutch to the driven disk, and hence to the input shaft of the gearbox, due to the friction forces that arise between the disks when the clutch is engaged. In this position, due to the elasticity of the pressure spring, the pressure plate clamps the driven disc between itself and the flywheel with a force that prevents it from slipping. In this case, the release bearing and the pressure spring do not touch.
When you press the clutch pedal through the clutch cable and the fork, the release bearing presses the pressure spring of the clutch drive plate and presses the drive plate away from the flywheel, as a result of which the driven drive is released and the transmission of torque between the engine and gearbox stops.
The freewheel adjustment is automatic and occurs using a ratchet mechanism located near the clutch pedal.
