Title
(EN) FRICTION CLUTCH WITH WEAR TAKE-UP DEVICE FOR FRICTION LININGS, IN PARTICULAR FOR MOTOR VEHICLE
(FR) EMBRAYAGE A FRICTION A DISPOSITIF DE RATTRAPAGE D'USURE DES GARNITURES DE FRICTION, EN PARTICULIER POUR VEHICULE AUTOMOBILE
Abstract
(EN)
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).
(FR)
L'embrayage à friction comporte un plateau de réaction, un disque de friction (100), portant à sa périphérie externe au moins une garniture de friction (101), un plateau de pression (11), un couvercle (12) fixé sur le plateau de réaction, un diaphragme (13) agissant entre le couvercle (12) et le plateau de pression (11) par l'intermédiaire de moyens d'appui secondaire (17) et primaire (18), un dispositif de rattrapage d'usure comprenant des moyens à rampes (14) adaptés à coopérer avec des moyens de contre-rampes (15), une denture (19) avec laquelle coopère une vis sans fin (23) disposée tangentiellement, les moyens à rampes (14) étant solidaires en rotation de ladite denture (19), des moyens d'entraînement en rotation (20) de la vis sans fin (23) constitués par une roue à rochet solidaire en rotation de la vis sans fin (23) et commandés par l'intermédiaire d'une languette de commande (36) dont la course est limitée par une butée dite de contrôle (33), la vis sans fin (23) et la roue à rochet (20) étant portées par un support (22) solidaire du couvercle (12): la butée de contrôle (33), comme les moyens d'appui primaire (18), est ménagée sur le couvercle (12).
