(FR) APPAREIL DE TRANSMISSION DE COUPLE HYDROCINETIQUE A EMBRAYAGE DE VERROUILLAGE
Abstract
(EN)
The invention concerns a device wherein the linkage between the clutch piston (5) and the turbine wheel (1) is provided by means of a driving disc (22) mounted between the clutch disc (5) and the radial wall (2a) of the impeller casing, the helical damping springs (27) are maintained both in the curved housing of a support disc (15, 29) integral with the turbine wheel (1) and between the detent lugs (33) of an intermediate disc (32) mounted in the support disc, the driving disc (22) bears drivel lugs (24) meshing with the detent lugs (33), such that there is no axial friction between the lugs and the springs.
(FR)
Dans cet appareil, la liaison entre le piston d'embrayage (5) et la roue de turbine (1) se fait par l'intermédiaire d'un disque d'entraînement (22) monté entre le disque d'embrayage (5) et la paroi radiale (2a) du carter d'impulseur, les ressorts hélicoïdaux d'amortissement (27) sont maintenus à la fois dans des logements arqués d'un disque de support (15, 29) solidaire de la roue de turbine (1) et entre des pattes d'arrêt (33) d'un disque intermédiaire (32) monté dans le disque de support, le disque d'entraînement (22) porte des pattes d'entraînement (24) s'engrenant avec les pattes d'arrêt (33), de sorte qu'il n'y a pas de frottement axial entre les pattes et les ressorts.
