The invention relates to a rear-drive active steering electric drive axle. A first drive motor is connected with a first central speed reducer, and the first central speed reducer is connected with a first hub speed reducer. The second driving motor is connected with the second central speed reducer; and the second central speed reducer is connected with the second wheel-side speed reducer. The first hub reduction gear is connected with one end of the first half shaft, and the other end of the first half shaft is connected with the differential mechanism. The second hub reduction gear is connected with one end of the second half shaft, and the other end of the second half shaft is connected with the differential mechanism. The rear-drive active steering electric drive axle is novel in structural arrangement, different from an existing rear wheel follow-up steering implementation mode, active steering of rear wheels can be achieved, the trafficability of a vehicle can be improved at a low speed, the handling stability of the vehicle can be improved at a high speed, and the risks of tire abrasion and side tipping can be reduced.

    本发明涉及一种后驱主动转向电驱桥,第一驱动电机与第一中央减速器连接,第一中央减速器与第一轮边减速器连接。第二驱动电机与第二中央减速器连接,第二中央减速器与第二轮边减速器连接。第一轮边减速器与第一半轴的一端连接,第一半轴的另一端与差速器连接;第二轮边减速器与第二半轴的一端连接,第二半轴的另一端与差速器连接。该后驱主动转向电驱桥,结构布置新颖,与现有后轮随动转向的实施方式不同,能够实现后轮的主动转向,低速时可提高车辆通过性,高速时可提高车辆操纵稳定性,可以减少磨胎以及侧倾的风险。
