A clutch mechanism comprising a wear take-up device including a ring with ramps bearing an outer toothing and set between a pressure plate and support member (engagement zones) to constitute a pressure plate with varying thickness between its friction surface and the support member. A box having a worm screw cooperates with the toothing. A brake strap borne by the pressure plate and cooperating with the ramp ring is arranged such that in the vent of axial vibrations or overtravel of the clutch during declutching, the ramps do not rotate and there is no wear take-up. |
