The invention discloses a dual-motor coaxial symmetric three-mode electric drive axle which comprises a left drive motor, a right drive motor, a drive axle shell, a left mode switching mechanism, a right mode switching mechanism, a centralized drive mode power transmission mechanism, an open differential mechanism, a left half shaft and a right half shaft. Three working modes including a single-motor centralized driving mode, a double-motor centralized driving mode and a double-motor distributed driving mode can be achieved, the three working modes can be switched at will, and the dynamic property, economical efficiency and active safety of the vehicle under the complex and changeable working conditions are improved.

    本发明公开了一种双电机同轴对称三模式电驱动桥,包括:左侧驱动电机、右侧驱动电机、驱动桥壳体、左侧模式切换机构、右侧模式切换机构、集中式驱动模式动力传动机构、开放式差速器、左侧半轴、右侧半轴组成。本发明可以实现单电机集中式驱动模式、双电机集中式驱动模式、双电机分布式驱动模式三种工作模式,并且三种工作模式之间可以任意切换,提升了车辆在复杂多变工况下的动力性、经济性和主动安全性。
