Abstract
A device for taking up clearance designed to equip a diaphragm friction clutch, having circumferentially distributed ramps designed to cooperate with the thrust plate of the clutch, support areas designed to receive the axial force of the diaphragm of the clutch and a toothing designed to drive them in rotation: the device consists of a ring having on one of its faces ramps alternating circumferentially with support areas constituting the support area.
Claims6
A diaphragm friction clutch having a friction disc (6) carrying friction linings (7), a thrust plate (1) designed to cooperate with the friction disk (6), a diaphragm (3), support means (14) designed to receive an axial force of the diaphragm (3), toothing means (18) arranged to drive the support means (14) in rotation, ramp means disposed axially between the diaphragm (3) and the thrust plate (1) and comprising a ring (11) having on one of its faces circumferentially distributed ramps (15) designed to cooperate with the thrust plate, said ring carrying the support means (14) for the diaphragm (3) wherein the ramps (11) are designed to cooperate with studs (4) carried by the thrust plate, and wherein said studs are distributed circumferentially at a first distance from each other which corresponds to a second distance which circumferentially separates two successive ramps (15).
