The invention discloses a dual-motor speed reducer driving system and a vehicle. The dual-motor speed reducer driving system comprises a first motor, a second motor, a third motor and a fourth motor, a second output shaft of the second motor is provided with a second primary driving gear capable of rotating along with the second output shaft; a first-stage driven gear and a second-stage driving gear are fixed to the transmission shaft, and the first-stage driven gear is in meshing transmission with the first first-stage driving gear and the second first-stage driving gear; and the differential assembly is fixedly provided with a second-stage driven gear, and the second-stage driving gear is in meshing transmission with the second-stage driven gear. Different torque requirements can be met by adopting the two motors, the two motors share one first-stage driven gear and two-stage speed reduction, so that the structure is simple, and compared with the mode that the two motors independently correspond to one speed reducer, the cost is effectively reduced through the technical scheme; due to the fact that one speed reducer is omitted, energy loss in the transmission process can be reduced, and the transmission efficiency is improved.

    本发明公开了一种双电机减速器驱动系统和车辆,双电机减速器驱动系统包括:第一电机,第一输出轴上设置有能够随第一输出轴转动的第一一级主动齿轮;第二电机,第二输出轴上设置有能够随第二输出轴转动的第二一级主动齿轮;传动轴,固定有一级从动齿轮和二级主动齿轮,一级从动齿轮与第一一级主动齿轮和第二一级主动齿轮均啮合传动;差速器总成,固定有二级从动齿轮,二级主动齿轮与二级从动齿轮啮合传动。采用双电机可满足不同的扭矩需要,并且两个电机共用一个一级从动齿轮以及二级减速,使得结构简单,相较于双电机单独对应一套减速器,本申请的技术方案有效降低了成本;由于减少一套减速器,可减小传递过程中的能量损失,从而提高了传动效率。
