Title (EN) ELECTRIC VEHICLE DRIVE DEVICE
(FR) DISPOSITIF DE PROPULSION DE VÉHICULE ÉLECTRIQUE
(JA) 電動車両駆動装置
Abstract:
(EN) The electric vehicle drive device according to the present invention includes: a first motor having a first rotor, a first stator, and a first coil; a second motor having a second rotor, a second stator, and a second coil; and a transmission device to which motive power of at least one of the first motor and the second motor is transmitted. A plane passing through a first end portion and orthogonal to the rotation axis is defined as a first plane, the first end portion being an end portion located at the extreme end in the axial direction among the end portion of the first rotor, the end portion of the first stator, and the end portion of the first coil in the axial direction. A plane that passes through a second end portion located at the extreme end opposite to the first end portion in the axial direction and is orthogonal to the rotation axis is defined as a second plane. At least a part of the second rotor, at least a part of the second stator or at least a part of the second coil is located between the first plane and the second plane.
(FR) Le dispositif de propulsion de véhicule électrique selon la présente invention comprend : un premier moteur comportant un premier rotor, un premier stator et une première bobine ; un second moteur comportant un second rotor, un second stator et une seconde bobine ; et un dispositif de transmission auquel la puissance motrice d'au moins l'un du premier moteur et du second moteur est transmise. Un plan passant à travers une première partie d'extrémité et orthogonal à l'axe de rotation est défini comme un premier plan, la première partie d'extrémité étant une partie d'extrémité située à l'extrémité extrême dans la direction axiale parmi la partie d'extrémité du premier rotor, la partie d'extrémité du premier stator et la partie d'extrémité de la première bobine dans la direction axiale. Un plan qui passe à travers une seconde partie d'extrémité située à l'extrémité extrême à l'opposé de la première partie d'extrémité dans la direction axiale et est orthogonal à l'axe de rotation est défini comme un second plan. Au moins une partie du second rotor, au moins une partie du second stator ou au moins une partie de la seconde bobine est située entre le premier plan et le second plan.
(JA) 電動車両駆動装置は、第1ロータ、第1ステータ及び第1コイルを有する第1モータと、第2ロータ、第2ステータ及び第2コイルを有する第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を備える。軸方向における第1ロータの端部、第1ステータの端部及び第1コイルの端部のうち軸方向で最も端位置する第1端部を通り且つ回転軸に対して直交する平面を第1平面とする。軸方向で第1端部とは反対側の最も端に位置する第2端部を通り且つ回転軸に対して直交する平面を第2平面とする。第2ロータの少なくとも一部、第2ステータの少なくとも一部又は第2コイルの少なくとも一部は、第1平面と第2平面との間に位置する。
