A continuously variable transmission device has planetary members (23) in rolling contact with radially inner and outer races (12, 14; 36, 37) each comprising axially spaced relatively axially movable parts, and control means (18) for determining the axial separation of the parts (12, 14) of one of the two races, in which the planetary members (23) are connected for drive transmission to an input or output member (30) of the transmission device by connection means which allows the radial position of the planets to vary in response to variation in the axial separation of the parts (12, 14) of the said one of the two races (37), and in which the generatrix of the curved surface (70, 71) of at least one of the races (37) and/or planetary members (23) is non-circular.
Un dispositif de transmission à variation continue comprend des éléments planétaires (23) qui sont en contact par roulement avec des chemins de roulement radialement internes et externes (12, 14; 36, 37) comprenant chacun des parties axialement espacées et relativement axialement mobiles et un moyen de commande (18) qui détermine la séparation axiale des parties (12, 14) d'un des deux chemins de roulement, dans lesquels les éléments planétaires (23) sont couplés pour assurer la transmission de l'entraînement à un élément d'entrée ou de sortie (30) du dispositif de transmission à l'aide d'un moyen de connexion qui permet à la position radiale des roues planétaires de varier en réponse à la variation de la séparation axiale des parties (12, 14) dudit chemin de roulement (37) et dans lequel la génératrice de la surface courbe (70, 71) d'au moins un des chemins de roulement (37) et/ou des éléments planétaires (23) est non circulaire.
