Non-drive type rear axle for automobile

Abstract

The invention discloses a non-drive type rear axle for an automobile, which comprises a rear axle tube, wherein the two sides of the rear axle tube are upwards and symmetrically provided with left and right rear hub axle seats; the rear axle tube close to the left and the right hub axle seats is successively and symmetrically provided with left and right steel plate spring seats and left and right rear damper lower seats; and the left and the right steel plate spring seats are fixedly connected above the rear axle tube through an arc-shaped plate matched with the external arc surface of the rear axle tube. The non-drive type rear axle has the advantages that the structure is simple; the production cost of the whole automobile can be reduced to meet the requirements of the commercial functions; the left and the right steel plate spring seats are fixedly connected above the rear axle tube to enhance the lateral tilted stability of the whole automobile and reduce the cost of the whole automobile on the premise of guaranteeing the safety; and the left and the right rear hub axle seats arranged on the two sides of the rear axle tube meet the requirements on the strength of the limit longitudinal force and the lateral force stood when rear wheels brake and turn, and the requirements on the whole strength and the reliability of the rear axle shell are guaranteed.
