The driven clutch disc is located on the splines of the drive gear of the gearbox and can move freely between the surfaces of the flywheel and the pressure plate. The dual friction linings on the outer side of the disc are attached to the internally splined hub by 6 spring dampers, which dampen the initial shock when the clutch is engaged.
The drive gear is located on the crankshaft, from which it is separated by a double-row needle bearing. The clutch is located outside the pinion gear teeth, which mesh with the input shaft of the gearbox. Although this design requires a more complex seal system, it allows the clutch to be removed and worked on without disturbing the gearbox.
The clutch mechanism is located at the end of the crankshaft, with which it is engaged by means of a conical polyhedron (trihedron). To remove the clutch from the crankshaft, a special tool is required. The pressure plate is driven by a release bearing sliding on the mounting sleeve and pressing on the fingers of the diaphragm spring. Due to this, the pressure plate ring moves away from the friction linings of the driven disk, and the transmission of torque from the clutch to the drive gear stops.
The release bearing is moved by the clutch release lever, which is operated by a cable and a release spring. The other end of the cable is attached to the clutch pedal.
When the clutch pedal is pressed, the cable moves the clutch release lever, which in turn moves the release bearing, which presses on the fingers of the diaphragm spring. The outer edge of the spring lifts the pressure plate, moving it away from the driven plate, which then becomes stationary despite the fact that the clutch basket continues to rotate. In this state, there is no transmission of torque from the pinion to the gearbox.
When the clutch pedal is released, the reverse process takes place. The driven disk is clamped between the pressure plate and the flywheel, and torque begins to be transmitted from the pinion gear to the gearbox.
