Title
(EN) FRICTION CLUTCH WITH WEAR TAKE-UP DEVICE FOR FRICTION LININGS, PARTICULARLY 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, in particular for a motor vehicle, comprising a reaction plate, a friction disc (100), bearing on its outer periphery at least a friction lining (101), a pressure plate (11), a cover (12) fixed on the reaction plate, axially operating clutching means (13) which operate 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 being provided, activated by the wear of the friction linings (101) when the clutch is engaged, consisting of a ratchet locked in rotation with the endless screw (23) both borne by a support (22) integral with the cover (12): the endless screw (23) is friction-mounted on the support (22).
(FR)
Embrayage à friction, en particulier pour véhicule automobile, du genre comportant 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, des moyens embrayeurs à action axiale (13) qui agissent entre, d'une part, le couvercle (12) et, d'autre part, 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 étant prévus, rendus opérationnels par l'usure de la ou des garnitures de friction (101) lorsque l'embrayage est embrayé, constitués par une roue à rochet solidaire en rotation de la vis sans fin (23) toutes deux portées par un support (22) solidaire du couvercle (12) : la vis sans fin (23) est montée à frottement sur le support (22).
