Abstract

L'invention concerne une boîte de vitesses automatique d'un véhicule électrique à énergie nouvelle. Lorsqu'un moteur tourne vers l'avant, un engrenage de sortie de moteur (1-1) entraîne la rotation d'un engrenage d'entrée entraîné à grande vitesse (3-1) sur un arbre intermédiaire (3) de façon à commander la rotation d'un pignon (6-1) à grande vitesse; lorsque le moteur tourne en sens inverse, un embrayage (3-5) est relié à un engrenage d'entrée entraîné à faible vitesse (3-2), l'engrenage de sortie de moteur entraîne un engrenage d'entrée entraîné en marche arrière (2-1) en rotation, et un engrenage de sortie d'entraînement à faible vitesse (2-2) commande la rotation de l'engrenage d'entrée entraîné à faible vitesse (3-2) de façon à commander la rotation à faible vitesse du pignon (6-1); lors du recul du véhicule, le moteur tourne en sens inverse, l'embrayage (3-5) est relié à un engrenage d'entrée entraîné par le recul (3-3), un engrenage de sortie d'entraînement de recul (2-3) entraîne la rotation d'un engrenage d'entrée de recul entraîné (4-2), et un engrenage de sortie de recul d'entraînement (4-1) entraîne davantage la rotation de l'engrenage d'entrée entraîné par l'arrière (3-3) de façon à commander le pignon (6-1) de tourner en sens inverse.
