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: The invention concerns a friction clutch, for a heat engine motor vehicle, comprising a reaction plate, a friction disc, a pressure plate, a cover, the pressure plate consisting of 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 (12A, 12B), 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 means (24), one of the ramps being arranged at the periphery of an inertial part (12A).
