According to the double-motor multi-gear electric driving system, the scheme that the two electric driving bridges are coaxially arranged is adopted, through more coaxial arrangement, the space utilization rate can be increased, the size and occupied space of the electric driving system are reduced, the internal structure is reduced, and the vehicle body mass is reduced; the power density can be further improved; by changing the positions of the first clutch device and the second clutch device, four gears where the double motors work at the same time can be combined, and when every two adjacent gears are switched, it is guaranteed that one motor always continuously outputs power, the situation of gear shifting interruption is avoided, and gear shifting comfort is guaranteed; the fourth forward gear can be directly shifted back to the first forward gear, and the process is also free of power interruption.

    本发明提供一种双电机多挡电驱动系统,采用两处共轴布置的电驱桥方案,通过更多的共轴布置,可提升空间利用率,缩小电驱动系统的体积和占用空间,减少内部结构,减轻车身质量,通过第一半轴、中间轴、及第二电机输入轴形成的三轴嵌套,可以进一步提升功率密度;通过改变第一和第二离合装置的位置,可以组合出四个双电机同时工作的挡位,且每相邻挡位进行切换时,保证总有一个电机在持续输出动力,避免换挡中断状况的发生,保证了换挡的舒适性;第四前进挡位可以直接换回第一前进挡位,这个过程也是无动力中断的。
