Abstract

L'invention concerne un dispositif d'entraînement pour un véhicule comprenant un ensemble de transmission (1). Un couple moteur et une puissance motrice sont appliqués par un moteur d'entraînement (2) dans l'ensemble de transmission (1) par l'intermédiaire d'un arbre d'entraînement (3) comprenant une première roue solaire (4). L'ensemble de transmission (1) comprend un engrenage à superposition (5) permettant la répartition par moitié de la puissance motrice sur une première couronne (7) reliée à un premier arbre de sortie (6a). Ledit dispositif d'entraînement comprend également un porte-satellites (8) relié indirectement à un deuxième arbre de sortie (6b), ainsi qu'un mécanisme de renversement de marche (9) relié mécaniquement à l'engrenage à superposition (5) par l'intermédiaire du porte-satellites (8) et permettant la répartition par moitié du couple moteur sur le premier et le deuxième arbre de sortie (6a, 6b). En outre, un premier train planétaire (10a) est monté sur le porte-satellites (8) et s'engrène au moins indirectement entre la première roue solaire (4) et la première couronne (7). Selon l'invention, l'engrenage à superposition (5) comprend un deuxième train planétaire (10a, 10b), qui est monté sur le porte-satellites (8) conjointement avec le premier train planétaire (10a), les deux trains planétaires (10a, 10b) s'engrenant l'un avec l'autre, et le mécanisme de renversement de marche (9) comprenant un premier et un deuxième train planétaire (11a, 11b), qui sont montés sur un porte-satellites (17) commun et qui s'engrènent l'un avec l'autre.
