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

Friction clutch with wear take-up device for friction linings, in particular for motor vehicle, provided with means indicating degree of said wear

The invention concerns a friction clutch in particular for motor vehicle, comprising a reaction plate (,), a friction disk (,), bearing friction linings (,), a pressure plate (,), a cover (,), clutch means (,) controlled by disengaging means and operating between the cover (,) and the pressure plate (,) through support means (,), a wear take-up device, one of the intermediate support means being capable of being axially offset and the wear take-up device comprising compensating means, actuated by actuating means, to produce said offsetting, controlled by triggering means combined with detecting means, sensitive to wear, operating on one at least of the actuating means, compensating means and triggering means: the wear take-up device also comprises means, called disconnecting means, making it inoperative before the linings are completely worn, adapted to act on the compensating means or the actuating means or the triggering means or the detecting means.
