According to the wheel-side double-motor coupling electric driving wheel set and the vehicle, an auxiliary driving motor is additionally arranged, a rotor output shaft of a main driving motor is connected with a high-speed gear shaft, the high-speed gear shaft and a low-speed gear form external meshing, and speed reduction and torque increase are achieved; a rotor output shaft of the auxiliary driving motor is connected with a high-speed gear clutch assembly through a high-speed input shaft, and the high-speed gear clutch assembly and a low-speed gear form external meshing; when the rotating direction of the high-speed input shaft is the same as that of the high-speed gear shaft, the main driving motor and the auxiliary driving motor realize dynamic coupling output and provide wheel set dynamic property; when the auxiliary driving motor does not work, the power can be output by the main driving motor, so that the energy consumption is reduced; the wheel set structure is suitable for heavy special carrying vehicles with high requirements for the minimum ground clearance and heavy electric drive vehicles for oil fields or mines.

    本发明提出了一种轮边双电机耦合电驱动轮组及车辆,增加一个辅助驱动电机,主驱动电机的转子输出轴与高速齿轮轴连接,高速齿轮轴与低速齿轮构成外啮合,实现减速增扭;辅助驱动电机的转子输出轴通过高速输入轴与高速齿轮离合器总成连接,高速齿轮离合器总成与低速齿轮构成外啮合;当高速输入轴旋转方向与高速齿轮轴旋转方向相同时,主驱动电机和辅助驱动电机实现动力耦合输出,提供轮组动力性;而且辅助驱动电机不工作时,可由主驱动电机动力输出,从而降低能耗;该轮组结构适用于对最小离地间隙要求较高的重型特种运载车辆、油田或矿山用重型电驱车辆。
