8.2. Coupling

General information

Coupling is intended for a rupture of power communication between the engine and RKPP when switching transfer and, thanks to frictional communication, provides smooth transfer of a torque on a running gear at a start of motion.

Coupling consists from корозины with a press disk and a conducted disk, and also a hydraulic drive with main and executive cylinders.

Coupling components

The basket of coupling by bolts fastens to a flywheel connected with cranked shaft of the engine. Between a press disk and a flywheel there is a conducted disk which nestles on a flywheel the press bearing of the executive cylinder. The conducted disk is connected with primary shaft of RKPP through shlitsevy connection.

When squeezing a pedal of coupling brake liquid from the general tank via the main cylinder of coupling under pressure is transferred in the executive cylinder. Vyzhimna the bearing of the executive cylinder influences petals of a diafragmenny spring. Thus press the disk is taken away from conducted and power communication between the engine and RKPP interrupts. Adjustment of a drive of coupling is not required.

At each inclusion and coupling switching off as a result of power influence there is a wear of frictional overlays of a conducted disk. The conducted disk represents a wearing-out detail, however average term of its service quite big and depends generally on load of the engine and style of driving.
