3.1.1. General information

Fig. 3.1. Coupling design: 1 – coupling casing; 2 – press disk; 3 – diaphragm spring; 4 – coupling switching off bearing; 5 – coupling switching off shaft; 6 – right case of the transmission; 7 – the conducted clutch plate; 8 – the torsion spring; 9 – bearing of the leading shaft; 10 – leading shaft; 11 – bent shaft; 12 – flywheel

Coupling with a diaphragm spring and hydraulic management, dry one-disk. A diaphragm spring with the trapezoid petals turned by a narrow part inside. The conducted disk with a damper with four cylindrical springs, is established on the leader to a transmission shaft on evolvent vents. The casing of coupling fastens to a flywheel, the diaphragm spring is located in such a way that a peripheral part of a spring presses press a disk to a flywheel (the conducted disk is between a flywheel and a press disk) when the pedal of switching off of coupling is not pressed. In this state coupling is included.

By pressing a pedal of coupling the coupling switching off bearing forward also presses petals of a diaphragm spring. At the same time the diaphragm spring separates press a disk from a flywheel, thus interrupting a power stream from an engine flywheel to the conducted clutch plate and the leading shaft of the transmission.
