The clutch consists of a friction disc, a pressure plate block, a hydraulic working cylinder, a release bearing.
All these components are installed in a cast aluminum casing - bell, making up "sandwich" between flywheel and gearbox. The friction disc is installed between the flywheel and the clutch pressure plate and is able to move along the splines of the primary drive of the gearbox. Friction linings are riveted on both sides of the friction disc, the disc hub has built-in springs to dampen transmission torsional vibrations when starting off. On all engines except AHL, the flywheel consists of two parts; the friction part of the flywheel has some possibility of damped movement in relation to the main massive flywheel, bolted to the heel of the crankshaft. This has the effect of smoothing out the primary shock of the clutch for smoother shifting.
When the clutch pedal is pressed, pressure is created in the hydraulic circuit through the rod of the angry cylinder, which, acting on the working cylinder, moves the lever (fork) forward, through the release bearing, presses on the clutch diaphragm spring. The spring is deformed, and the clutch force of the pressure plate with the friction plate is weakened, the engine torque is transferred to the gearbox input shaft.
When the clutch pedal is released, the reverse process occurs and the friction disc is clamped between the pressure plate and the flywheel. This causes the transmission of torque through the splined hub of the friction disc to the gearbox input shaft.
To facilitate pressing the pedal during its working stroke, a servo spring is installed on the pedal. Clutch - with automatic compensation of the free play of the fork when the friction linings are worn.
