The double-motor electric drive axle comprises a first motor, a second motor, a first output shaft and a second output shaft, the first output shaft and the second output shaft are coaxially arranged, and the outer side of the first output shaft and the outer side of the second output shaft are both connected to a hub; the first motor and the second motor are arranged in the radial direction, a motor shaft of the first motor is in transmission connection with the first output shaft through the first transmission assembly, a motor shaft of the second motor is in transmission connection with the second output shaft through the second transmission assembly, and the first motor and the second motor are both located between the first transmission assembly and the second transmission assembly in the axial position. In the radial position, the radial size of the first motor and the radial size of the second motor are not larger than the radial size of the first transmission assembly or the second transmission assembly. The invention has the main beneficial effects that the layout is reasonable, the axial size can be greatly reduced by the radial arrangement of the first motor and the second motor, the occupied chassis structure arrangement space is reduced, and the dynamic property and the economical efficiency of the whole vehicle can be both considered to the greatest extent.

    本发明揭示了一种双电机电驱驱动桥,包括第一电机和第二电机,同轴设置的第一输出轴和第二输出轴,第一输出轴和第二输出轴的外侧均连接于轮毂;第一电机和第二电机径向布置,第一电机的电机轴通过第一传动组件与第一输出轴传动连接,第二电机的电机轴通过第二传动组件与第二输出轴传动连接,在轴向位置上,第一电机和第二电机均位于第一传动组件和第二传动组件之间,在径向位置上,第一电机和第二电机的径向尺寸不大于第一传动组件或第二传动组件的径向尺寸。本发明的有益效果主要体现在:布局合理,第一电机和第二电机径向布置可以大幅度减少轴向尺寸,减小占用底盘结构布置空间,可最大成都上兼顾整车动力性和经济性。
