The invention discloses an automobile rear shock absorber connecting structure which comprises a self-tapping locking threaded sleeve, the self-tapping locking threaded sleeve comprises a self-tapping lining and a locking threaded sleeve, triangular self-tapping threads are arranged on the outer side of the self-tapping lining, the self-tapping lining can be screwed into a mounting hole preset in a rear floor through the triangular self-tapping threads, and the locking threaded sleeve is connected with the self-tapping lining. The flange surface of the self-tapping bushing is attached to the upper mounting surface of the rear floor; the locking thread bushing is arranged on the inner side of the self-tapping bushing, and an additional thread self-locking area is arranged on the locking thread bushing; and the front end of the mounting bolt can sequentially penetrate through the rear shock absorber and the locking thread sleeve and is fixedly connected with the additional thread self-locking area. When the rear shock absorber connecting structure is located on the aluminum alloy die casting, the self-tapping locking threaded sleeve is adopted for an installation point, the connecting strength is high, the structure is simple, assembling is convenient, and the risk that after a rear shock absorber is used for a long time, connection is loose can be reduced.
本发明公开了一种汽车后减震器连接结构,包括:自攻锁紧螺纹套,其包括:自攻衬套和锁紧螺纹套,自攻衬套外侧设置有三角自攻螺牙,自攻衬套通过三角自攻螺牙能旋入后地板预设的安装孔内,且自攻衬套的法兰面与后地板的上安装面相贴合;锁紧螺纹套设置于自攻衬套的内侧,锁紧螺纹套上设置有附加螺纹自锁区;安装螺栓,其前端能够依次穿过后减震器和锁紧螺纹套并与附加螺纹自锁区固定相连。本申请的后减震器连接结构位于铝合金压铸件上时,安装点采用自攻锁紧螺纹套,连接强度高,结构简单,装配方便,可降低后减震器长时间使用后连接松动的风险。
