The invention discloses a double-motor independent drive synchronous gear shifting two-gear speed change system. The transmission is mainly composed of a first driving motor, a second driving motor, a first planetary gear train, a second planetary gear train, a first controllable bidirectional clutch, a gear shifting execution mechanism, a reverse gear execution mechanism, a third planetary gear train, a fourth planetary gear train, a second controllable bidirectional clutch, a first transmission shell, a second transmission shell, a left half shaft, a right half shaft, a left axle housing and a right axle housing. The axle comprises a left axle shaft sleeve, a right axle shaft sleeve, a left hub and a right hub. The invention further discloses the electric vehicle, independent control over the torque of the left wheel and the right wheel is achieved through distributed driving, two gears are arranged to meet the dual requirements of the electric vehicle for the dynamic property and the economical efficiency, and meanwhile the synchronous gear shifting function of the left wheel and the right wheel is achieved to improve the vehicle running stability and safety; in addition, the reverse gear function can be achieved without adding other clutches, centralized driving on the other side can be achieved when a single-side motor breaks down, and functional safety is improved.

    本发明公开了一种双电机独立驱动同步换挡两挡变速系统,其主要由第一驱动电机、第二驱动电机、第一行星轮系、第二行星轮系、第一可控双向离合器、换挡执行机构、倒挡执行机构、第三行星轮系、第四行星轮系、第二可控双向离合器、第一变速器壳体、第二变速器壳体、左半轴、右半轴、左桥壳、右桥壳、左半轴套管、右半轴套管、左轮毂和右轮毂构成。本发明还公开了一种电动汽车,其采用分布式驱动实现左右车轮转矩的独立控制,并设置两个挡位以满足电动汽车对动力性和经济性的双重需求,同时具备左右轮同步换挡功能以提高车辆行驶平稳性和安全性,此外无需增加其他离合器即可实现倒挡功能,另外在单侧电机故障时可实现另一侧集中驱动,提高功能安全。
