The invention relates to a motor speed reducer assembly, an integrated electric drive axle assembly and a vehicle. The motor speed reducer assembly comprises a speed reducer shell; the motor is fixed to the speed reducer shell, and the axis is parallel to the axis of the half shaft; the differential mechanism is arranged in the speed reducer shell, the differential mechanism and the motor are distributed in the radial direction of the half shafts, the differential mechanism comprises a differential mechanism shell and a differential gear pair used for connecting the left half shaft and the right half shaft, and the differential mechanism shell can rotate around the axis of the wheel half shaft relative to the speed reducer shell; the transmission mechanism comprises a first-stage reducer and a second-stage reducer, the input end of the first-stage reducer is connected to the motor, the output end of the first-stage reducer is connected to the input end of the second-stage reducer, and the output end of the second-stage reducer is connected to the differential mechanism shell. The motor and the differential mechanism are arranged in the X direction of the vehicle body, the structure is compact in the Y direction of the vehicle body, the mass center of the motor deviates from the center of the axle housing slightly when the motor is arranged, the X-direction space of the electric drive axle is compact, the motor, the differential mechanism and the speed reducer are integrated in the speed reducer shell, and the integration degree is high.
