reibungskupplung with a verschleiu00dfnachstellvorrichtung for friction linings, in particular for motor vehicles, with information on the verschleiu00dfgrad

摘要

The invention concerns a clutch friction, comprising a reaction plate (202) designed to be locked in rotation on an input shaft, a friction disk (200), bearing at its external periphery at least one friction lining (201), designed to be locked in rotation on an output shaft, a pressure plate (1), a cover (2) fixed on the reaction plate (202), clutch means with axial action (3) controlled by releasing means and which operate between the cover (2) and the pressure plate (1) via support means (14), the pressure plate (1) being interlocked in rotation with the cover (2) while being capable of moving axially relative thereto and subjected to the action of elastic return means returning the pressure plate (1) axially towards the cover (2). Said friction clutch further comprises a wear take-up device, one of the supports of the clutch means (3) being capable of being axially offset: the wear take-up device further comprises means, called diverging means, adapted to modify rapidly, for a predetermined degree of wear of the friction lining (201), the position of the elements controlling the releasing means.
