An electrically-driven axle of a vehicle comprises an axle housing, a speed reducer and a motor, the speed reducer comprises an outer shell and a transmission assembly, the outer shell is fixed to the axle housing, the motor is arranged in a space defined by the outer shell and the axle housing, a shell of the motor comprises a front end face and a rear end face opposite to the front end face, the front end face is fixedly connected to the outer shell, and the output end of the motor is connected with the transmission assembly. A support is fixed on the axle housing, a connecting seat is arranged between the motor shell and the support, one end of the connecting seat is fixedly connected with the support, at least one buffering assembly is arranged between the other end of the connecting seat and the rear end face of the motor shell, and the buffering assembly comprises a supporting rod and a damping sleeve arranged outside the supporting rod in a sleeving mode. The damping sleeve is embedded in a through hole formed in the other end of the connecting seat, and the end, facing the rear end face of the motor shell, of the supporting rod protrudes out of the connecting seat and is fixedly connected with the rear end face of the motor shell. The rear end of the motor is buffered through the damping sleeve, the motor is protected, and the service life of the motor is prolonged.

    车辆的电驱动车桥,包括桥壳、减速器、电机,减速器包括外壳、传动组件,外壳固定在桥壳上,电机置于外壳与桥壳围成的空间内,电机的壳体包括前端面、以及与前端面相对的后端面,前端面固定连接在外壳上,并且电机的输出端与传动组件联接,桥壳上固定有支座,电机壳体与支座之间设置有连接座,连接座的一端与支座固定连接,另一端与电机壳体的后端面之间设置至少一个缓冲组件,该缓冲组件包括支撑杆、套设在支撑杆外部的减震套,减震套嵌置在连接座另一端开设的通孔中,支撑杆朝向电机壳体后端面的一端凸出于连接座并与电机壳体的后端面固定连接。本发明利用减震套对电机的后端部进行缓冲,对电机起到保护的作用,增加了电机的使用寿命。
