Abstract

L'invention se rapporte à une poulie d'entraînement (10) mise en oeuvre dans une transmission à changement de vitesses continu (CVT). Cette poulie comporte un axe principal (12), une bride fixe (14) et une bride mobile (16). Un premier système à came comporte une came de commande (22) dotée de surfaces (24) et des galets de came (28) correspondants. Un second système à came comporte également une came de commande (40) dotée de surfaces (42) et des galets de came (46) correspondants. Au cours d'une rotation normale vers l'avant de la poulie d'entraînement (10), qui correspond à un déplacement vers l'avant du véhicule, le premier système à came est automatiquement désactivé et la position de la bride mobile (16) est commandée par le second système à came. Cependant, dans des conditions de débrayage du moteur, le premier système à came assure la commande et le second système à came est désactivé. De manière analogue, le premier système à came commande le positionnement de la bride mobile (16) au cours d'une rotation inverse normale de la poulie d'entraînement (10) et le second système à came assure la commande dans des conditions de débrayage du moteur lorsque le véhicule se déplace vers l'arrière.
