The invention relates to an axle housing of a drive axle, and discloses an automobile axle housing with side impact energy absorption structures. The automobile axle housing comprises an axle housing,wherein half-axle mounting sections are arranged at the two ends of the axle housing; the half shaft mounting sections are provided with side impact energy absorption structures; each side impact energy absorption structure comprises an annular air cylinder, a compression piston and a driving frame, wherein the annular air cylinder is arranged in the half shaft installation section, surrounds thehalf shaft installation channel and extends in the left-right direction, the compression piston is connected into one end of the air cylinder in a sealed and sliding mode, and the driving frame drives the compression piston. The half shaft installation sections are provided with long-strip-shaped receding holes extending in the left-right direction, the driving frames are arranged in the long-strip-shaped receding holes in a penetrating mode, a spraying hole is formed in the other end of each air cylinder, and a sealing head which is pressed out by air in the air cylinder when the air pressure in the air cylinder rises to a set value is connected in each spraying hole. The automobile axle housing has the advantage that side impact energy can be absorbed during side impact, and the problemof poor safety caused by the fact that an automobile body needs to collapse to absorb energy during side impact of an existing automobile is solved.
本发明涉及驱动桥的桥壳。一种设侧碰吸能结构的汽车桥壳,包括桥壳,桥壳的两端设有半轴安装段,半轴安装段设有侧碰吸能结构,所述侧碰吸能结构包括设置在半轴安装段内的环绕在半轴安装通道外的沿左右方向延伸的环形的气缸、密封滑动连接在气缸一端内的压缩活塞和驱动压缩活塞的驱动架,所述半轴安装段设有沿左右方向延伸的长条形避让孔,所述驱动架穿设在所述长条形避让孔内,所述气缸的另一端设有喷射孔,所述喷射孔内连接有当所述气缸内的气压上升到设定值时被气缸内的气体压出的密封头。本发明具有产生侧碰时可吸收侧碰能量的优点,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的问题。
