The invention belongs to the technical field of new energy automobiles, and discloses a novel steering electric drive axle which comprises an axle housing, two fork-shaped steering knuckles and a drive half axle, a parallel shaft type driving speed reducer is arranged on the axle housing, and the parallel shaft type driving speed reducer is arranged in the direction, opposite to the vehicle advancing direction, of the axle housing. The parallel shaft type driving speed reducer is arranged at an upward included angle relative to the plane where the axis of the axle housing is located, a mounting support aligned with the parallel shaft type driving speed reducer is arranged on the axle housing, a motor is arranged on the mounting support, and the output end of the motor is connected with the input end of the parallel shaft type driving speed reducer. The two fork-shaped steering knuckles are arranged at the two ends of the axle housing respectively, and a transverse pull rod is connected between the two fork-shaped steering knuckles and located below the parallel shaft type driving speed reducer. The tie rod is arranged in the direction, opposite to the vehicle advancing direction, of the axle housing, namely the vehicle retreating direction, the problem that the tie rod is arranged in the vehicle advancing direction and is not beneficial to steering trapezoid design is solved, and therefore the tie rod is matched with the steering trapezoid design.

    本发明属于新能源汽车技术领域,公开了一种新型转向电驱动桥,包括桥壳、两个叉形转向节和驱动半轴,桥壳上设置有平行轴式主动减速器,平行轴式主动减速器布置于桥壳在车辆前进方向相反的方向上,平行轴式主动减速器相对于桥壳轴线所在平面呈向上夹角设置,桥壳上设置有与平行轴式主动减速器对位的安装支架,安装支架上设置有电机,电机的输出端与平行轴式主动减速器的输入端连接;两个叉形转向节分别设置在桥壳的两端,两个叉形转向节之间连接有横拉杆,横拉杆位于平行轴式主动减速器的下方。横拉杆布置于桥壳在车辆前进方向相反的方向上,即车辆后退方向上,解决了横拉杆布置于车辆前进方向不利于转向梯形设计的问题,从而适配转向梯形设计。
