The invention discloses a pure electric automobile motor axle which comprises a gearbox, a first motor, a second motor, a third motor, a fourth motor, a first battery box, a second battery box, a third battery box and a fourth battery box. The first motor and the second motor are symmetrically arranged at the two ends of one side of the gearbox, the third motor and the fourth motor are symmetrically arranged at the two ends of the other side of the gearbox, and therefore an H-shaped symmetrically-distributed bridge type structure is integrally formed. The first battery box and the second battery box are symmetrically arranged along the transverse central axis of the gearbox, the third battery box and the fourth battery box are symmetrically arranged along the transverse central axis of the gearbox, and the first battery box and the fourth battery box are symmetrically arranged along the vertical central axis of the gearbox. The motor axle adopts a completely symmetrical layout structure, so that the mass distribution of the whole vehicle is uniform, the gravity center of the whole vehicle is reduced as much as possible, the driving safety of the vehicle is greatly improved, four motor boxes can be arranged, the total endurance exceeds thousand kilometers, and the endurance mileage requirement of a pure electric vehicle is met.

    本发明公开了一种纯电汽车电机桥:包括变速箱、一号电机、二号电机、三号电机、四号电机、电池盒一、电池盒二、电池盒三、电池盒四;一号电机、二号电机对称布置在变速箱一侧两端部,三号电机、四号电机对称布置在变速箱另一侧两端部,从而整体形成H型对称分布的桥式结构;电池盒一、电池盒二沿变速箱横向中心轴对称设置,电池盒三、电池盒四沿变速箱横向中心轴对称设置,电池盒一、电池盒四沿变速箱竖向中心轴对称设置。本发明电机桥采用完全对称布局结构,使得整车质量分布均匀且整车重心尽可能降低,故而大大提高车辆行驶的安全性,可以布置4个电机盒,从而总续航超千公里,满足了纯电汽车续航里程要求。
