Abstract

L’invention concerne un dispositif de transmission de couple (1) pour un véhicule automobile comprenant au moins un moteur (2), comprenant :- un premier arbre de sortie (14) couplé en rotation à un élément de sortie (12) d’un premier embrayage (E1) et à un élément de sortie (13) d’un deuxième embrayage (E2), le premier arbre de sortie (14) étant destiné à entrainer une première roue du véhicule,- un deuxième arbre de sortie (17) couplé en rotation à un élément de sortie (15) d’un troisième embrayage (E3) et à un élément de sortie (16) d’un quatrième embrayage (E4), le deuxième arbre de sortie (17) étant destiné à entrainer une deuxième roue du véhicule, opposée à la première roue,- un mécanisme de transfert de couple (5, R1, R2, R3, 7, R5, R6, R7, R8, R9, R10) agencé pour transmettre le couple du moteur (2) à un élément d’entrée (9) du premier embrayage (E1) et à un élément d’entrée (10) du quatrième embrayage (E4) selon un premier rapport de vitesses, et pour transmettre le couple du moteur (2) à un élément d’entrée (11) du deuxième embrayage (E2) et à un élément d’entrée (11) du troisième embrayage (E3) selon un deuxième rapport de vitesses.
