The clutch is designed to briefly disconnect the engine and transmission when shifting gears or braking and smoothly connect them when the car starts moving, as well as to protect transmission parts from dynamic loads.
The clutch is single-disk, dry, permanently closed, with a central pressure spring and a torsional vibration damper on the driven disk. The primary shaft of the gearbox protrudes in the gearbox housing, on which the release bearing is located, which does not require maintenance, and outside the housing there is a clutch release lever, to which the clutch cable is attached.
The principle of operation of the clutch is based on the transmission of torque from the flywheel and the leading part of the clutch to the driven disk, and therefore to the primary 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 disk clamps the driven disk 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 the clutch pedal is pressed, the release bearing presses the pressure spring of the clutch drive disc through the clutch cable and fork and pushes the drive disc away from the flywheel, as a result of which the driven disc is released and the transmission of torque between the engine and gearbox stops.
Free travel adjustment is automatic and occurs using a ratchet mechanism located near the clutch pedal.
