Patent

CA 2677552

A continuously variable transmission is disclosed, which includes an input shaft receiving a rotational force input from the outside, a plurality of driven gears arranged around the input shaft to have uniform phase differences to receive a driving force from the input shaft, a variable cam varied in its radius of rotation by an external load, a variable input link receiving the rotational force of the input shaft by being rotatably connected to the input shaft, a plurality of one-way clutches receiving bidirectional rotational forces transmitted to the respective driven gears in only one direction, and thereby rotating the driven gears in one direction, a plurality of cam shafts inscribed or circumscribed to the one-way clutches, and a plurality of output links all in the same length, of which one ends are revolved about the rotational center of the variable input link along with the variable cam and the other ends are rotatably connected to the respective cam shafts.

La présente invention concerne une transmission à variation continue, qui comprend un arbre primaire recevant une force de rotation de l'extérieur, une série d'engrenages commandés disposés autour de l'arbre primaire afin d'assurer des phases différentielles uniformes pour recevoir une force d'entraînement de l'arbre primaire, une came variable dont le rayon de rotation varie sous l'effet d'une charge extérieure, une tringlerie d'entrée qui reçoit la force de rotation de l'arbre primaire en étant raccordé à ce dernier afin de tourner, une série d'embrayages à roue libre recevant des forces de rotation bidirectionnelles transmises aux engrenages commandés respectifs dans une seule direction, et faisant ainsi tourner les engrenages commandés dans une direction, une série d'arbres à came inscrits ou circonscrits aux embrayages à roue libre, ainsi qu'une série de tringleries de sortie, toutes de la même longueur, dont les unes extrémités tournent autour de l'axe de rotation de la tringlerie d'entrée variable, de concert avec la came variable, et les autres extrémités sont raccordés aux arbres à came respectifs afin de tourner.
