Abstract

The invention relates to a drive axle assembly in which a shock absorber assists in absorbing side impact energy, comprising an axle housing and a rear beam whose two ends are supported on both ends of the axle housing through shock absorbers, and the middle part of the axle housing is provided with a reducer installation cavity , the reducer installation cavity is provided with two half-shaft installation passages that correspond to the two end faces of the axle housing, the half-shaft installation passage is pierced with a half-shaft, and the outer end of the half-shaft The rear wheels are connected; the present invention also includes two longitudinal bumpers distributed on both sides of the vehicle frame, and the longitudinal bumpers are connected with the rear beam through the side impact energy canceller of the axle housing. The invention has the advantages of absorbing the energy of the side impact without the collapse and deformation of the frame when the side impact occurs, and the shock absorber supporting the frame participates in the energy absorption, and solves the problem that the vehicle body collapses and absorbs energy when the side impact of the existing automobile is required. The problem of poor security.

Description

technical field [0001] The invention relates to a drive axle of an automobile, in particular to a drive axle assembly in which a shock absorber assists in absorbing side collision energy. Background technique [0002] The bridge frame of the car is composed of the frame, the rear axle (drive axle) supporting the frame and the front axle of the car (also known as the front axle, which is the steering axle). Both ends of the drive axle and the front axle are connected to the wheels, and the frame passes through the suspension Attached to the frame. [0003] The composition of drive axle is composed of final reducer, differential, half shaft and axle housing. The final drive, differential, and drive axle components are installed in the drive axle housing, located at the rear of the car, and the power is transmitted to the rear wheels. Promptly disclose a kind of existing axle housing in the patent document of CN205853768U in Chinese patent announcement. The basic structure o...
