Abstract

L'invention concerne un mécanisme à double embrayages (10) dont chaque système d'actionnement (300A, 300B) comprend une chambre de pression (750A, 750B) agencée pour recevoir un fluide pressurisé, un piston (105, 205) mobile axialement dans la chambre de pression (750A, 750B) afin d'embrayer ou de débrayer l'embrayage (100, 200) correspondant, une chambre d'équilibrage (700A, 700B) située à l'opposé de la chambre de pression (750A, 750B) par rapport au piston (105, 205), et un élément de rappel élastique (800A, 800B) logé dans la chambre d'équilibrage et agencé pour exercer un effort axial contre ledit piston (105, 205). Selon l'invention, le piston (105, 205) de chaque système d'actionnement (300A, 300B) est formé par une première partie (105P, 205P) s'étendant radialement à l'extérieur de la chambre de pression et une deuxième partie (105Q, 205Q) située radialement à l'intérieur de la première partie (105P, 205P). La deuxième partie (105Q, 205Q) du piston (105, 205) est fixée solidairement à ladite première partie (105P, 205P) par un moyen de liaison (400A, 400B) qui délimite partiellement la chambre d'équilibrage correspondante. L'invention concerne aussi un système de transmission (1) comprenant un tel mécanisme à double embrayages (10).
