Abstract
The utility model relates to a two-gear variable-speed drive axle box body for an electric vehicle. The two-gear variable-speed drive axle box body for the electric vehicle comprises a left box body and a right box body. The left box body and the right box body are respectively provided with end surfaces mutually connected in a sealing butt joint mode, concentric input shaft installment holes and concentric differential mechanism output shaft holes are arranged on the left box body and the right box body. The outer end surfaces of the differential mechanism output shaft holes are axle housing connecting surfaces. A motor installment hub is arranged outside an input shaft installment hole of the right box body, and the end surface of the motor installment hub is a flange surface connected with a vehicle drive motor. Annular reinforcing ribs are arranged on the connecting portion of the left box body and a drive axle and on the connecting portion of the right box body and the drive axle. Reinforcing ribs are arranged on the inner wall of the motor installment hub of the right box body. The two-gear variable-speed drive axle box body for the electric vehicle has the advantages that structural arrangement is more compact, mechanical property is guaranteed because the reinforcing ribs are evenly arranged on connecting portions and the annular reinforcing ribs and reinforcing ribs connected with the body are arranged on portions where the body is connected with the drive axle, improving safety and reliability of the drive axle, and prolonging service life of the drive axle.
