| 摘要 |
The invention concerns a friction clutch comprising a reaction plate, a friction disc (100), bearing at its outer periphery at least a friction lining (101), a pressure plate (11), a cover (12) fixed on the reaction plate, a diaphragm (13) operating between the cover (12) and the pressure plate (11) via secondary (17) and primary (18) support means, a wear take-up device comprising ramp means (14) adapted to co-operate with counter-ramp means (15), a toothing (19) wherewith co-operates a tangentially arranged endless screw (23), the ramp means (14) being locked in rotation with said toothing (19), means driving in rotation (20) the endless screw (23) consisting of a ratchet locked in rotation with the endless screw (23) and controlled via a control tab (36) whereof the travel is limited by a so-called control stop (33), the endless screw (23) and the ratchet (20) being borne by a support (22) integral with the cover (12): the control stop (33), as well as the primary support means (18), is arranged on the cover (12). |
