Title
(EN) ELECTRIC VEHICLE DRIVE DEVICE
(FR) DISPOSITIF D’ENTRAÎNEMENT DE VÉHICULE ÉLECTRIQUE
(JA) 電動車両駆動装置
Abstract
(EN) This electric vehicle drive device comprises a first motor, a second motor, a gearshift device to which motive power from at least one of the first motor and second motor is transmitted, and an output member rotated by motive power outputted from the gearshift device. A rotating shaft of the first motor, a rotating shaft of the second motor, and a rotating shaft of the gearshift device are disposed parallel to the rotating shaft of the output member. When the electric vehicle drive device is observed from an axial direction parallel to the rotating shaft of the output member, the rotating shaft of the first motor is positioned on one side of a straight line passing through the rotating shaft of the output member and the rotating shaft of the gearshift device, and the rotating shaft of the second motor is positioned on the other side of the straight line.
(FR) La présente invention concerne un dispositif d’entraînement de véhicule électrique qui comprend un premier moteur, un deuxième moteur, un dispositif de changement de vitesse auquel une puissance motrice provenant d’au moins l’un parmi le premier moteur et le deuxième moteur est transmise, et un élément de sortie entraîné en rotation par la puissance motrice délivrée par le dispositif de changement de vitesse. Un arbre rotatif du premier moteur, un arbre rotatif du deuxième moteur et un arbre rotatif du dispositif de changement de vitesse sont disposés parallèlement à l’arbre rotatif de l’élément de sortie. Lorsque le dispositif d’entraînement de véhicule électrique est observé depuis une direction axiale parallèle à l’arbre rotatif de l’élément de sortie, l’arbre rotatif du premier moteur est positionné sur un côté d’une ligne droite traversant l’arbre rotatif de l’élément de sortie et l’arbre rotatif du dispositif de changement de vitesse, et l’arbre rotatif du deuxième moteur est positionné sur l’autre côté de la ligne droite.
(JA) 電動車両駆動装置は、第1モータと、第2モータと、第1モータ及び第2モータの少なくとも一方の動力が伝達される変速装置と、変速装置から出力される動力により回転する出力部材と、を備える。第1モータの回転軸、第2モータの回転軸、及び変速装置の回転軸は、出力部材の回転軸と平行に配置されている。出力部材の回転軸と平行な軸方向から見た場合、出力部材の回転軸と変速装置の回転軸とを通る直線の一方側に第1モータの回転軸が位置し、直線の他方側に第2モータの回転軸が位置する。
