The invention relates to an automobile front axle, and discloses an automobile front axle with side impact energy absorption structures. The automobile front axle comprises a front axle, wherein the front shaft comprises a cross rod and two cantilevers located at the two ends of the cross rod, the left end and the right end of a sliding rod are each provided with a side impact energy absorption structure, the side impact energy absorption structure comprises an air cylinder which is arranged in the cross rod and extending in the left-right direction, a compression piston connected into one endof the air cylinder in a sealed and sliding mode, and a driving frame for driving the compression piston, the cross rod is provided with a long-strip-shaped receding hole extending in the left-rightdirection, the driving frame is arranged in the long-strip-shaped receding hole in a penetrating mode, a spraying hole is formed in the other end of the 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 the spraying hole. According to the automobile front axle with the side impact energy absorption structures, side impact energy can be absorbed without crumpling deformation of an automobile frame when side impact occurs, and the problem of poor safety due to the fact that an automobilebody needs to crumple to absorb energy when an existing automobile is subjected to side impact is solved.
本发明涉及汽车前轴。一种设侧碰吸能结构的汽车前轴,包括前轴,所述前轴包括横杆和位于横杆两端的两个悬臂,所述滑杆的左右两端各设有一个侧碰吸能结构,所述侧碰吸能结构包括设置在横杆内的沿左右方向延伸的气缸、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,所述横杆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的设侧碰吸能结构的汽车前轴,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。
