Abstract

L'invention concerne un dispositif d'entraînement destiné à un véhicule, comprenant un système de transmission (1). L'introduction d'un couple d'entraînement et d'une puissance d'entraînement provenant d'un moteur d'entraînement (2) dans le système de transmission (1) se fait par l'intermédiaire d'un arbre d'entrée (3) muni d'un premier pignon planétaire (4). Le système de transmission (1) comprend une transmission de superposition (5) permettant une répartition par moitié de la puissance d'entraînement sur un deuxième pignon planétaire (7) relié à un premier arbre de sortie (6a) et sur une première couronne (8) reliée indirectement à un deuxième arbre de sortie (6b), ainsi qu'un mécanisme de renversement de marche (9) relié mécaniquement à la transmission de superposition (5) par l'intermédiaire de la première couronne (8) pour une répartition par moitié du couple d'entrainement sur le premier et le deuxième arbre de sortie (6a, 6b). Par ailleurs, un premier train planétaire (10a) est monté sur un porte-satellites (12) de la transmission de superposition (5) et vient en prise entre le premier pignon planétaire (4) et la première couronne (8). Selon l'invention, la transmission de superposition (5) comporte un deuxième train planétaire (10b) qui vient en prise avec le deuxième pignon planétaire (7) et qui est monté avec le premier train planétaire (10a) sur le porte-satellites (12), les deux trains planétaires (10a, 10b) venant en prise l'un avec l'autre. Le mécanisme de renversement de marche (9) comporte un premier et un deuxième train planétaire (11a, 11b) qui sont montés sur un porte-satellite commun (13) et viennent en prise l'un avec l'autre.
