Abstract

La présente invention concerne un ensemble réducteur électrique pur à double moteur. L'ensemble comprend : un carter gauche (1) ; un carter droit (3) ; une plaque de raccordement (2) installée entre les parties médianes du carter gauche (1) et du carter droit (3) ; un premier ensemble arbre d'entrée (4) installé entre le carter gauche (1) et la plaque de raccordement (2) ; un second ensemble arbre d'entrée (5) installé entre le carter droit (3) et la plaque de raccordement (2) ; un ensemble arbre intermédiaire (6) installé au niveau des extrémités inférieures du premier ensemble arbre d'entrée (4) et du second ensemble arbre d'entrée (5) ; et un ensemble différentiel (7) installé au niveau de l'extrémité inférieure de l'ensemble arbre intermédiaire (6). La présente invention résout le problème de puissance insuffisante fournie à un moteur unique. Deux arbres d'entrée portent des charges d'entrée simultanément de manière à réduire les exigences de résistance pour des pièces associées sur les arbres d'entrée et réduisent la difficulté de fabrication et le coût de production. En même temps, un entraînement à double moteur est utilisé pour éviter le problème selon lequel l'ensemble du véhicule ne peut pas fonctionner en raison d'un mauvais fonctionnement d'un moteur unique ou d'une structure de transmission partielle. L'ensemble présente une structure simple et des propriétés stables.
