General information

Coupling is located between the engine and a transmission and intended for separation and connection of the flywheel located on cranked to a shaft of the engine and primary shaft of a transmission.

Coupling consists of a conducted (frictional) disk, a casing of coupling with a press disk and a diafragmenny spring, and the mechanism of switching off of coupling. The frictional disk consists of two ring frictional slips which are strengthened on a nave through dempferny springs.

The Diafragmenny spring mechanism creates effort which unites work of a flywheel, press and conducted disks for ensuring joint rotation, in this case coupling joins and transfers a torque from the engine to a transmission. Management of coupling is carried out by a coupling pedal.

Switching off of coupling is made as follows. As a result of pressing a pedal of coupling the piston in the main cylinder moves, compressing the liquid which pressure on a hose is transferred to the working cylinder of the coupling which piston, in turn, influences a fork of switching off of coupling. The fork of switching off of coupling moves the bearing of switching off of coupling which presses the center of a diafragmenny spring, thus releasing effort of inclusion on perimeter of a spring and moves press a disk back. The conducted disk then the shaft of the engine and a shaft of a transmission can rotate independently from each other is thus released.

From two parties of a conducted disk frictional slips are fixed. The leading part of a disk incorporates to a nave through details of a quencher of krutilny fluctuations which provides elastic communication between them. The quencher of fluctuations reduces the dynamic loadings causing a twisting (raskruchivaniye) of shaft of transmission which arise at sharp change of speed of movement of the car, arrival on roughness of the road, at sharp inclusion of coupling, and also owing to unevenness of a torque of the engine. Elastic fluctuations of details of transmission lead to emergence of noise in mechanisms and units, and also to vibrations therefore damage of details in case the amplitude of elastic fluctuations reaches considerable sizes is possible. For absorption of energy of elastic krutilny fluctuations the quencher serves.
