Problems solved by technology

[0005] The present invention provides a side impact energy-absorbing driving axle assembly that can absorb side impact energy without frame collapse and deformation when a side impact occurs, and the shock absorber supporting the vehicle frame also participates in side impact energy absorption, which solves the problem Some cars need to collapse the body to absorb energy when they collide sideways, resulting in poor safety and a single function of the shock absorber

Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] see Figure 1 to Figure 4 , an energy-absorbing drive axle assembly with a side impact, including a vehicle frame, a drive axle 1 and a vertically telescopic automobile shock absorber. The vehicle frame is provided with a drive axle beam 3 and a water tank 6 . The two ends of the driving axle each support the vehicle frame through an automobile shock absorber 18, specifically supporting the crossbeam 3 of the driving axle. The drive axle includes an axle housing 7 . The middle part of the axle housing is provided with a reducer installation cavity. A reducer 8 is installed in the reducer installation cavity. The reducer installation chamber is provided with two half-shaft installation passages that correspond to each other through the two end faces of the axle housing, and the half-shaft installation passage is provided with a half-shaft 9 ...

Abstract

The invention relates to a drive axle assembly with side impact energy absorption. The drive axle assembly comprises a frame and a drive axle, and the two ends of the drive axle respectively support the frame through automobile shock absorbers. The drive axle assembly is characterized in that the drive axle assembly further comprises two side bumpers distributed on the two sides of the frame in the length direction of the drive axle, the frame is provided with a drive axle portion beam located above the drive axle, and the side bumpers are connected with the drive axle portion beam through drive axle portion side collision energy absorption mechanisms. According to the drive axle assembly with side impact energy absorption, side impact energy can be absorbed without crumpling deformation of the frame when side impact occurs, and the shock absorbers supporting the frame also participate in side impact energy absorption, so that the problems of poor safety and single function of the shock absorbers due to the fact that an automobile body needs to crumple and absorb energy when side impact occurs to an existing automobile are solved.

Description

technical field [0001] The invention relates to automobiles, in particular to an energy-absorbing drive axle assembly with side impact. Background technique [0002] The car includes 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 is supported by the shock absorber. on the bridge. [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 of the existing axle housing includes the axle housing body. The axle housing bod...
