General information
The clutch is located between the engine and the gearbox and is designed to disconnect and connect the flywheel located on the engine crankshaft and the input shaft of the gearbox.
The clutch consists of a slave (friction) disc, clutch housing with pressure plate and diaphragm spring, and clutch release mechanism. The friction disc consists of two annular friction linings, which are secured to the hub via damper springs.
The diaphragm spring mechanism creates a force that combines the work of the flywheel, pressure plate and driven plate to ensure joint rotation, in which case the clutch is engaged and transmits torque from the engine to the gearbox. The clutch is controlled by the clutch pedal.
The clutch is disengaged as follows. As a result of pressing the clutch pedal, the piston in the master cylinder moves, compressing the fluid, the pressure of which is transmitted through the hose to the clutch slave cylinder, the piston of which, in turn, acts on the clutch release fork. The release fork moves the release bearing, which presses on the center of the diaphragm spring, thus releasing the engagement force around the perimeter of the spring and moving the pressure plate rearward. This releases the driven disk, after which the engine shaft and gearbox shaft can rotate independently of each other.
Friction linings are fixed on both sides of the driven disk. The leading part of the disc is connected to the hub through the parts of the torsional vibration damper, which provides an elastic connection between them. The vibration damper reduces dynamic loads that cause twisting (unwinding) transmission shafts, which occur when the vehicle's speed changes abruptly, when driving over uneven roads, when the clutch is suddenly engaged, and also as a result of uneven engine torque. Elastic vibrations of transmission parts lead to the appearance of noise in mechanisms and units, as well as vibrations, which may result in damage to parts if the amplitude of elastic vibrations reaches significant values. A damper is used to absorb the energy of elastic torsional vibrations.
