All models are equipped with a dry single-disc clutch, which consists of a driven and pressure disc, a central diaphragm spring, a casing and a clutch release bearing.
The driven clutch disc moves freely on the splines of the input shaft of the gearbox and is clamped between the flywheel and the pressure plate by the force created by the central diaphragm spring. Friction linings are riveted to both sides of the driven disk. The driven clutch disc is connected to the hub through the torsional vibration damper components. The need for a torsional vibration damper is caused by the fact that with a sharp change in the vehicle's speed, driving over uneven roads, abrupt engagement of the clutch, as well as due to uneven engine operation, dynamic loads arise in the vehicle's transmission, causing twisting (unwinding) transmission shafts. Uneven engine torque can cause significant overloads in the transmission due to the occurrence of torsional vibrations and resonance when the frequencies of the transmitted loads coincide with the natural frequencies of the transmission. Elastic vibrations of the transmission lead not only to the occurrence of noise in mechanisms and units, but also to dangerous vibrations, and sometimes to breakdowns of parts when the amplitude of vibrations reaches a large value. The energy of torsional vibrations is absorbed by the damper.
The clutch release drive is hydraulic. The clutch release bearing is mounted on the front side of the gearbox on the clutch release sleeve. The bearing is moved by the clutch release fork. When you press the clutch pedal, the piston in the master cylinder moves and compresses the fluid, which flows through the hose into the clutch slave cylinder. Under pressure, the piston of the clutch slave cylinder moves and activates the clutch release fork. The clutch release fork moves the bearing, which acts on the pressure plate spring and moves the pressure plate away from the driven disc of the clutch. The clutch is adjusted automatically.
Note: When the clutch is in operation, the friction linings wear out, resulting in the formation of dust containing asbestos, which is harmful to health. Therefore, when cleaning the clutch, do not use compressed air or inhale the dust. Cleaning of clutch parts from dust must be done using brake fluid or methyl alcohol. After cleaning the parts, wipe them dry.
