Abstract

L'invention concerne un module hybride (1) pour la chaîne de traction d'un véhicule à moteur, comprenant une machine électrique (4) équipée d'un stator (2) et d'un rotor (3), deux dispositifs d'embrayage (6, 7) disposés l'un à côté de l'autre le long de l'axe de rotation (5) du rotor (3), ainsi que deux systèmes d'actionnement (8, 9) comprenant un premier système d'actionnement (8) qui règle la position du premier dispositif d'embrayage (6) et un second dispositif d'actionnement (9) qui règle la position du second dispositif d'embrayage (7), les deux système d'actionnement (8, 9) étant au moins partiellement adjacents aux deux dispositifs d'embrayage (6, 7) sur un même côté axial. L'invention concerne en outre une chaîne de traction hybride pour un véhicule à moteur équipé dudit module hybride (1).
