The invention provides a power driving system of a dual-motor torque coupling structure. Comprising a machine shell, a first motor with a first motor output shaft, a second motor with a second motor output shaft, a first motor driving wheel, a first-gear driving wheel, a second motor driving wheel, a power output shaft, a main reduction gear, a first-gear driven wheel, a second-gear driven wheel, a second-gear driving wheel and a gear shifting executing mechanism, the gear shifting executing mechanism is connected with the first-gear driving wheel and the second motor driving wheel when at the first gear, and the gear shifting executing mechanism is separated from the first-gear driving wheel and connected with the second-gear driven wheel and the second motor driving wheel when at the second gear. According to the power driving system of the dual-motor torque coupling structure, the currently used medium-low speed motor is replaced by the high-speed motor, so that the motor cost is reduced. The whole structure is compact, the gear sleeve is adopted for transversely shifting to be connected with the first-gear driving wheel and the second-gear driven wheel on the two sides, the function of gear shifting without power interruption is achieved, the number of parts is small, and cost is low.

    本发明提供一种双电机扭矩耦合结构的动力驱动系统,包括机壳以及设置在机壳内的带有电机一输出轴的电机一、带有电机二输出轴的电机二、电机一主动轮、一档主动轮、电机二主动轮、动力输出轴、主减齿轮、一档从动轮、二挡从动轮、二挡主动轮以及换挡执行机构,所述换挡执行机构在一档时衔接一档主动轮和电机二主动轮,换挡执行机构在二挡时脱离一档主动轮,并衔接二挡从动轮和电机二主动轮。该双电机扭矩耦合结构的动力驱动系统,将现在使用的中低速电机由高速电机代替,降低电机成本。整体结构紧凑,采用齿套横向拨动与两边的一档主动轮、二挡从动轮衔接,具有无动力中断换挡的功能,零部件数量较少,成本较低。
