(FR) ENSEMBLE DE TRANSMISSION DE COUPLE POUR BOITE DE VITESSES
Abstract: front page image
(EN)Torque-transmitting assembly for a motor vehicle gearbox, comprising a clutch (2) that has a friction disc (48) and a vibration damping flywheel capable of driving the rotation of an input element (25) of the clutch, the clutch comprising a pressure plate (36) that is axially fixed and a movable pressure plate (37) that can be moved axially under the action of an actuating member (38), the two pressure plates (31, 37) sandwiching the friction disc (48) and elastic urging means (39) tending to move the two pressure plates (36, 37) towards one another, characterized in that this assembly comprises means (52) for amplifying the clamping force applied to the movable pressure plate (37).
(FR)Ensemble de transmission de couple pour boîte de vitesses de véhicule automobile comprenant un embrayage (2) à disque de friction (48) et un volant amortisseur de vibrations capable d'entraîner en rotation un élément d' entrée (25) de l' embrayage, l' embrayage comprenant un plateau de pression (36) fixe axialement et un plateau de pression mobile (37) déplaçable axialement sous l' action d'un organe d' actionnement (38), les deux plateaux de pression (31 , 37) enserrant le disque de friction (48) et des moyens de sollicitation élastique (39) tendant à serrer les deux plateaux de pression (36, 37) l'un vers l' autre, caractérisé par le fait qu' il comprend des moyens (52) d' amplification de l' effort de serrage appliqué sur le plateau de pression mobile (37).
