The invention discloses an automobile thrust rod spherical hinge structure assembly imitating a locust foot pad, which comprises a thrust rod spherical hinge, a thrust rod connecting rod, a thrust rod end cover and a clamp spring, the thrust rod spherical hinge comprises an internal core shaft and an external rubber body, and a plurality of bionic salient points imitating the locust foot pad are constructed on the surface of the external rubber body. The thrust rod connecting rod is provided with a mounting hole, the thrust rod spherical hinge is connected into the mounting hole in an interference mode, and the thrust rod end cover is provided with two limiting thrust rod spherical hinges coaxially arranged on the inner walls of the top and the bottom of the inner wall of the mounting hole. According to the structure, the surface-surface contact of the thrust rod spherical hinge rubber body and the inner wall of the end of the thrust rod connecting rod is optimally designed into a bionic non-smooth surface, the surface-surface contact is formed, the contact area is greatly increased, abnormal sound generated by relative rotation of assembly parts in the low-temperature environment in the using process is avoided, and the service life of the thrust rod is prolonged. And reference is provided for later development and application of low-temperature noise reduction.

    本发明专利公开了一种仿蝗虫足垫的汽车推力杆球铰结构总成,包括推力杆球铰、推力杆连杆、推力杆端盖、卡簧,所述推力杆球铰包含内部芯轴和外部橡胶体,所述外部橡胶体表面构建出多个仿蝗虫足垫的仿生凸点,推力杆连杆设置有安装孔,所述推力杆球铰过盈接入在安装孔内部,所述推力杆端盖设置有两个同轴设置在安装孔内壁顶部和底部内壁上限位推力杆球铰。该结构将推力杆球铰橡胶体与推力杆连杆端部内壁的面‑面接触优化设计为仿生非光滑表面,形成面‑面接触,大大增大了接触面积,在使用过程中避免了低温环境下装配件相对转动产生的异响,为以后低温降噪减噪的发展与应用提供了借鉴。
