8. Coupling
Coupling consists of the conducted (frictional) disk, a casing of coupling with a press disk and a diaphragm spring and the coupling switching off mechanism. The frictional disk consists of two ring frictional slips which by means of rivets are strengthened on a nave with damping springs. The diaphragm spring on the periphery is rigidly attached by rivets to a coupling casing through basic rings concerning which the diaphragm of a spring can cave in. In process of wear of frictional slips it is necessary to regulate a coupling drive cable.
