Drive axle assembly with side impact energy absorption

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...
