Abstract

L'invention concerne un dispositif de transmission à variation de vitesse comprenant un variateur de vitesse à galets déplaçables radialement entre des plateaux sur des arbres de guidage. Suivant l'invention, la liaison entre galets et arbres de guidage est réalisée par des pièces d'entraînement organisées pour être déplacées axialement le long desdits arbres, pour solidariser en rotation les galets et les arbres, pour autoriser la libre inclinaison des galets autour de la droite qui passe par les points de contact entre galets et plateaux. L'invention trouve une application principale aux transmissions automatiques pour véhicule automobile.
