Abstract

L'invention porte sur un dispositif d'embrayage, dans lequel dispositif de l'huile d'embrayage est efficacement conduite jusqu'à des plaques de frottement et des plaques d'embrayage, de façon à améliorer les performances de lubrification de l'huile embrayage ainsi que l'efficacité de transmission de force d'entraînement. Un dispositif d'embrayage (100) comporte un centre d'embrayage (105) pour supporter des plaques d'embrayage (107) disposées de façon à faire face à des plaques de frottement (103) amenées en rotation et entraînées par un arbre de premier moteur. Le centre d'embrayage (105) comporte une section d'engrènement (105c) disposée radialement à l'extérieur d'une section de liaison (105a), une section de bride (105b) étant présente entre celles-ci, la section de liaison (105a) étant reliée à un arbre d'entraînement (114) apte à délivrer de l'huile d'embrayage. La section d'engrènement (105c) comporte un trou de conduction d'huile (105d) pour conduire de l'huile d'embrayage jusqu'aux plaques de frottement (103) et aux plaques d'embrayage (7). Un corps de guidage d'huile d'embrayage du type paroi (108) est formé entre la section de liaison (105a) et la section d'engrènement (105c) de telle manière que le côté de section d'engrènement (105c) du corps de guidage d'huile d'embrayage (108) s'étend vers l'arrière dans la direction dans laquelle le centre d'embrayage (105) est amené à tourner et est entraîné.
