A parallel shaft type rear motor electric drive axle belongs to the technical field of electric vehicles and comprises a motor, a shaft A, a shaft B, a shaft C and a gear shifting mechanism. An output shaft of the motor is connected with one end of a shaft A, and the other end of the shaft A is provided with a shaft A gear; a shaft B high-gear gear and a shaft B low-gear gear are arranged at the two ends of the shaft B respectively, and a shaft C high-gear gear and a shaft C low-gear gear are rotationally arranged on the shaft C in a sleeving mode; the shaft A gear is meshed with a shaft B high-gear gear, the shaft B high-gear gear is meshed with a shaft C high-gear gear, and a shaft B low-gear gear is meshed with a shaft C low-gear gear; the gear shifting mechanism can connect a shaft C high-gear gear with the shaft C or connect a shaft C low-gear gear with the shaft C; and the shaft C is connected with a hub reducing mechanism through a planetary reducing mechanism and a differential mechanism assembly. The parallel shaft type rear motor electric drive axle is reasonable in design and ingenious in structure, the chassis space is saved, more batteries can be conveniently arranged, the endurance mileage of a vehicle can be effectively increased, and development of an electric vehicle is facilitated.
