Abstract: A heat engine motor vehicle, having a reaction plate, a friction disc, a pressure plate, a cover, the pressure plate being two half-plates, axially mobile relative to each other, under the action of device compensating play resulting from wear which comprises a pair of complementary ramps circumferentially arranged axially associated respectively with each of the two half-plates one of the ramps being designed to move circumferentially relative to the other ramp in the direction increasing the thickness of the pressure plate, and prevented from moving in the other direction by a one-way mechanism, one of the ramps being arranged at the periphery of an inertial part. A monitoring mechanism, is provided to control the wear compensation device.

Abstract: A friction clutch comprising a pressure plate (12) consisting of tow half-plates (12A, 12B) integral in rotation with the input shaft but axially mobile, relative to each other, under the action of the device compensating play due to wear. The wear compensating device comprises a pair of complementary ramps (17, 18) circumferentially arranged, axially associated respectively with each of the half-plates (12A, 12B), one support ramp (17) being integral in rotation to one (12B) of the half-plates, the other adjustment ramp (18) being adapted to move circumferentially relative to the support ramp (17) in the compensating direction increasing the global thickness of the first plate (12) and prevented form moving in the other direction by one-way means (24). The circumferential movement is controlled by a tripping element (22) sensitive to wear condition, the adjusting ramp (18) being arranged at the periphery of an inertial piece (12A).
