Abstract

La présente invention se rapporte à une transmission à changement de vitesse continue. Une unité de base de changement de vitesse de la transmission à changement de vitesse continue est une fourchette de changement de vitesse qui glisse de façon rectiligne sur des trains d'engrenages à changement de multiples engrenages, et de multiples engrenages peuvent être changés lorsqu'un groupe de fourchettes de changement de vitesse glissent le long d'une ligne droite. Une puissance d'entrée est distribuée à trois embrayages au moyen d'engrenages (7). Trois embrayages (1, 3, 5) et trois trains d'engrenages sont commandés à l'aide d'une roue de changement de vitesse (17). Grâce à une rotation de 120 degrés, la roue de changement de vitesse peut effectuer des actions de séparation et de combinaison sur deux embrayages parmi les trois embrayages et effectuer des actions de changement de position d'engrenage sur le train d'engrenages sous un autre embrayage de séparation. Les trois trains d'engrenages mettent en œuvre une sortie de torsion par l'utilisation conjointe d'un train d'engrenages (11) d'arbre de sortie, et une augmentation et une baisse de vitesse peuvent être mises en œuvre au moyen d'une rotation avant et arrière de la roue de changement de vitesse, de manière à augmenter et à réduire en continu et rapidement les vitesses; et la roue de changement de vitesse est commandée de façon précise par un moteur pas à pas (20), ce qui permet d'augmenter et de réduire de façon stable la vitesse de rotation de sortie.
