According to the dual-motor multi-gear electric drive system, the scheme that three electric drive bridges are coaxially arranged is adopted, and through more coaxial arrangement, the space utilization rate can be increased, the size and occupied space of the electric drive system can be reduced, the internal structure can be reduced, and the mass of a vehicle body can be reduced; by changing the positions of the first clutch device and the second clutch device, three 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; and the third clutch device arranged on the intermediate shaft is correspondingly jointed with the three-gear output gear of the empty sleeve, so that the effect of increasing one gear by only increasing one gear is realized.
本发明提供一种双电机多挡电驱动系统,采用三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;通过改变第一和第二离合装置的位置,可以组合出三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;通过在中间轴上设置的第三离合装置与空套的三挡输出齿轮的对应接合,实现了仅增加1个齿轮便增加1个挡位的效果。
