The invention discloses an automobile steering pull rod flexible connection structure which comprises a steering knuckle assembly and a steering pull rod assembly, the steering pull rod assembly comprises an outer ball pin used for being connected with the steering knuckle assembly, and the steering knuckle assembly comprises a steering knuckle body, a flexible component and a steering knuckle ring sleeve. A first mounting hole used for being matched with the outer ball pin is formed in the steering knuckle ring sleeve, a second mounting hole used for being matched with the steering knuckle ring sleeve is formed in the flexible component, and a third mounting hole used for being matched with the flexible component is formed in the steering knuckle body. The outer ball pin, the steering knuckle ring sleeve, the flexible component and the steering knuckle body are sequentially arranged from inside to outside in the radial direction of the connecting hole. Pavement excitation can be prevented from being transmitted to the interior of the steering gear and a steering wheel, so that steering abnormal sound and vibration are prevented, the driving comfort of the whole vehicle is improved, and meanwhile, internal abrasion of the steering gear can be prevented from being aggravated.

    本发明公开了一种汽车转向拉杆柔性连接结构,包括转向节总成和转向拉杆总成,所述转向拉杆总成包括用于与所述转向节总成连接的外球销,所述转向节总成包括转向节本体、柔性构件和转向节环套,所述转向节环套的内部设置有用于与所述外球销相适配的第一安装孔,所述柔性构件的内部设置有用于与所述转向节环套相适配的第二安装孔,所述转向节本体上设置有用于与所述柔性构件相适配的第三安装孔,所述外球销、所述转向节环套、所述柔性构件和所述转向节本体沿所述连接孔的径向从内至外依次设置。本发明能够防止路面激励传递至转向器内部以及方向盘上,从而防止出现转向异响以及震动,提高整车行驶舒适性,同时能够防止转向器内部磨损加剧。
