Abstract

La présente invention concerne un ensemble de poulies (1) pour une transmission variable continue d’un véhicule, comprenant un arbre (2) doté d’un axe (A), un élément support (7) tournant autour de l’axe (A), une première demi-poulie (9) connectée de façon rotative à l’élément support (7), une seconde demi-poulie (11) faisant face à la première demi-poulie (9) pour définir un siège (13a) conçu pour loger une courroie (13) de la transmission, au moins une de la première et seconde demi-poulie (9, 11) étant longitudinalement mobile par rapport à l’élément support (7), et un embrayage (8) pour coupler sélectivement par rotation l’arbre (2) à l’élément support (7). L’ensemble de poulies (1) comprend en outre un moyen de couplage unidirectionnel (23) interposé entre l’élément support (7) et l’arbre (2) pour permettre l’entraînement de l’arbre (2) lorsque la vitesse angulaire de l’élément support (7) tend à dépasser celle de l’arbre (2).
