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.
本发明涉及一种设侧碰吸能驱动桥总成,包括车架和驱动桥,所述驱动桥的两端各通过一个所述汽车减震器支撑住所述车架;其特征在于,还包括沿驱动桥的长度方向分布在所述车架两侧的2根侧保险杠,所述车架设有位于驱动桥上方的驱动桥部横梁,所述侧保险杠通过驱动桥部侧碰吸能机构同所述驱动桥部横梁连接在一起。本发明提供了一种产生侧碰时无须车架溃缩变形即可吸收侧碰能量且支撑车架的减震器也参与侧碰吸能的设侧碰吸能驱动桥总成,解决了现有的汽车侧碰时需要车身溃缩吸能而导致的安全性差且减震器功能单一的问题。
