Abstract

La présente invention concerne un appareil de transmission à variation continue, l'appareil de transmission à variation continue selon un mode de réalisation de la présente invention comprenant un boîtier, un train d'engrenages planétaires, un moteur et un système de commande, le train d'engrenages planétaires comprenant un premier ensemble d'engrenages planétaires et un engrenage arrière, et l'engrenage arrière étant à son tour divisé en un réducteur de vitesse et un second ensemble d'engrenages planétaires. Le train d'engrenages planétaires (PGT) comprend un premier ensemble d'engrenages planétaires qui divise l'entrée de puissance dans le premier support vers un premier planétaire et un second planétaire, des premier et second arbres de liaison qui transmettent la puissance divisée du premier ensemble d'engrenages planétaires à l'engrenage arrière, et un engrenage arrière transmettant une différence de vitesse de rotation entre le premier planétaire et le second planétaire à un arbre de commande. La présente invention conçue comme décrit ci-dessus ajuste la différence des vitesses de rotation entre les premier et second planétaires en faisant en sorte que le moteur règle la vitesse de rotation de l'arbre de commande, permettant ainsi une transmission à variation continue.
