The clutch located between the engine and the transmission and intended for separation and connection of the flywheel disposed on the crankshaft of the engine and a primary shaft of the gearbox.
Clutch consists of a conducted (frictional) disk, a casing of coupling with a press disk and diaphragm spring and clutch mechanism. The friction disc consists of two annular friction linings, which are mounted on the hub via the damper spring.
Diaphragm spring mechanism creates a force that integrates the work of the flywheel and the pressure of the driven disc for joint rotation, in this case, the clutch is turned on and transfers torque from the engine to the transmission. Management is carried out clutch pedal clutch.
Clutch follows. By pressing on the clutch pedal moves the piston in the master cylinder, compressing the fluid whose pressure is transmitted through the hose to the clutch slave cylinder, the piston which in turn acts on the clutch release fork. Clutch fork moves the clutch, which presses the center of the diaphragm spring, thus releasing the force switching on the perimeter of the spring and the pressure plate moves back. This releases the clutch disc, after which the motor shaft and the transmission shaft can rotate independently of each other.
On both sides of the slave disk attached friction linings. The leading portion of the disk is connected to the hub through the details of the torsional vibration damper, which provides a resilient connection between them. Vibration damper reduces the dynamic loads that cause twisting (unwinding) shafts transmissions that occur during a sudden change in the vehicle speed, running over bumps in the road, sharp inclusion of coupling, and also due to non-uniformity of torque. Elastic vibrations transmission parts cause noise in machinery and aggregates, as well as vibration, resulting in possible damage to the parts, if the amplitude of elastic vibrations reach considerable values. In order to absorb the energy of elastic torsional vibration damper is used.
