If this is actuated, performs the release lever through the intermediary of a mechanical or hydraulic connection between the clutch pedal and release lever pivotal movement, which is then converted by the physical contact of the release lever to the housing in an axial movement of the housing.

Abstract

L'invention concerne un système de débrayage (13) destiné à une butée de débrayage (1) et comportant, pour entraîner la butée de débrayage (1), un arbre rotatif (14) et des leviers (6) qui sont reliés à l'arbre (14) et qui sont reliés fonctionnellement à la bague intérieure (10) de la butée de débrayage (1) ou à son boîtier (3). Selon l'invention, pour améliorer la résistance à l'usure, chaque levier (6) est pourvu, du côté dirigé vers l'autre levier (6), d'un appendice (7) plat pivotant axialement et radialement à l'axe de rotation de l'arbre (14) et les deux appendices (7) portent contre des surfaces d'appui (5.1, 5.2) arrondies au niveau du boîtier (3).
