The invention belongs to the technical field of automobiles, and particularly relates to a double-planet-row electric drive system and a vehicle. The double-planet-row electric drive system comprises a first motor, a first planet row, a second motor and a second planet row. According to the double-planet-row electric drive system, speed reduction is achieved through the first planet row and the second planet row, the speed change effect is achieved through cooperation of the planet carriers and the sun gears in the first planet row and the second planet row, and therefore a traditional two-stage speed reduction scheme does not need to be adopted, and space occupation in the X-axis direction and the Z-axis direction is reduced; meanwhile, the number of bearings arranged in the gear is also reduced due to the fact that the transmission path is simplified through the double-planet-row structure, the requirement for bearing supporting points is lowered, and therefore reduction of transmission efficiency in an existing scheme can be avoided; besides, the output end of the first planet row is connected with the first wheel, the output end of the second planet row is connected with the second wheel, and therefore independent control and accurate power distribution of the two wheels are achieved.

    本申请属于汽车技术领域,具体涉及双行星排电驱系统和车辆。双行星排电驱系统包括:第一电机、第一行星排、第二电机和第二行星排。本申请的双行星排电驱系统,通过第一行星排和第二行星排实现减速,由于第一行星排和第二行星排中通过行星架与太阳轮的配合实现了变速效果,因此不需要再采用传统的二级减速方案,从而减少了X轴和Z轴方向的空间占用;同时也减少了齿轮中轴承设置的数量,这是因为双行星排结构简化了传动路径,降低了轴承支撑点的需求,从而能够避免现有方案中传动效率的降低;此外,在本申请中,第一行星排的输出端与第一车轮连接,第二行星排的输出端与第二车轮连接,从而实现对两个车轮的独立控制与精确动力分配。
