Abstract

L'invention concerne une transmission hybride parallèle pourvue d'un moteur à combustion interne (ICE) transmettant une énergie mécanique aux deux roues motrices d'un véhicule. Chaque roue motrice comprend un moteur sur moyeu correspondant avec un stator monté sur le véhicule et un rotor directement connecté à la roue motrice. L'interconnexion entre l'ICE et la roue motrice se fait par l'intermédiaire d'un joint de cardan positionné entre l'arbre de sortie de l'ICE et chaque roue motrice. Lorsque les moteurs sur moyeu sont alimentés, la transmission se trouve ainsi dans un mode hybride parallèle dans lequel l'ICE et les moteurs sur moyeu contribuent à la rotation de la roue. La transmission peut également se trouver en mode normal lorsque les moteurs sur moyeu ne sont pas alimentés, et en mode électrique lorsque l'ICE est arrêté.
