Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] see figure 1 with figure 2 , a drive axle assembly in which a shock absorber assists in absorbing side impact energy, including an axle housing 1 , a shock absorber 3 , a rear beam 5 and a water tank 7 . The middle part of the axle housing is provided with a reducer installation cavity 8 . A reducer 9 is installed in the reducer installation cavity. The reducer installation chamber is provided with two half-shaft installation channels 10 correspondingly passing through the two end faces of the axle housing. A half shaft 11 is pierced in the half shaft installation channel. The present invention also includes two longitudinal bumpers 19 distributed on both sides of the vehicle frame. The two ends of the rear beam are respectively supported on the two ends of the axle housing by a shock absorber. The longitudinal bumper is connected with the...

Abstract

The invention relates to a drive axle assembly with a shock absorber assisting in absorbing side impact energy. The drive axle assembly comprises an axle shell and a rear cross beam. Two ends of the rear cross beam are supported at the two ends of the axle shell through shock absorbers, a speed reducer installation cavity is formed in the middle of the axle shell, the speed reducer installation cavity is provided with two half shaft installation channels penetrating through the two end surfaces of the axle shell in a one-to-one correspondence mode, half shafts are arranged in the half shaft installation channels in a penetrating mode, and the outer ends of the half shafts are connected with rear wheels. The drive axle assembly further comprises two longitudinal bumpers distributed on the two sides of a frame, and the longitudinal bumpers are connected with the rear cross beam through axle shell part side impact energy dissipation devices. The drive axle assembly has the advantages thatside impact energy can be absorbed without crumpling deformation of the frame when side impact occurs, and the shock absorber supporting the frame participates in energy absorption so that a problemof poor safety caused by a fact that an automobile body needs to crumple to absorb energy during side impact of an existing automobile is solved.

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...
