Abstract

L'invention concerne une machine à transmission infiniment variable comprenant un élément d'entraînement souple sans fin, un agencement à piste de diamètre variable pour un élément entraîné, un moyen de variation de diamètre de piste, un arbre de sortie, une roue d'entrée entraînée entraînant l'élément entraîné, un moyen de tensionnement de l'élément entraîné, lors de la variation de l'agencement de piste, une pluralité de dispositifs d'extraction situés sur l'arbre de sortie, un bras s'étendant dans une direction radiale à partir de chaque dispositif d'extraction, l'élément entraîné étant relié à chaque bras, avec des intervalles d'espacement, sur sa longueur, et pouvant être déplacé dans une direction axiale des bras, de sorte que l'arbre de sortie se mette partiellement en rotation, par le biais de dispositifs d'extraction, tour à tour, pour provoquer une révolution unique de l'arbre de sortie, lorsque leurs bras atteignent une vitesse angulaire supérieure à celle de l'arbre de sortie, lorsque l'élément entraîné est entraîné sur l'agencement de piste.
