The invention belongs to the technical field of vehicle accessories, and particularly relates to a universal mechanism of a vehicle steering system. The universal mechanism comprises a frame, a suspension, a steering drive axle, a protective shell and a transmission, the frame is connected with the steering drive axle through the suspension, the steering drive axle is connected with a steering arm, and a positioning sleeve is wrapped outside the steering arm. The positioning sleeve is connected to the outer portion of the connecting position of the steering drive axle and the steering arm in athreaded mode, a positioning plate is connected into the positioning sleeve through a spring, the positioning plate is attached to the outer wall of the steering arm, and when the steering arm operates, better stable positioning performance can be achieved between the steering arm and the steering drive axle through the positioning plate and the spring; and meanwhile, when the protective shell isarranged outside the universal transmission device, a lubricating pipeline is arranged in the protective shell, and lubricating liquid in the lubricating pipeline can be circularly injected into a transmission groove, so that friction between the transmission groove and a transmission ball is reduced, and the service life of the device is prolonged.

    本发明公开的属于车辆配件技术领域,具体为一种车辆转向系统的万向机构,其包括车架、悬架、转向驱动桥、保护壳和变速器,所述车架通过所述悬架连接有所述转向驱动桥,所述转向驱动桥连接有转向臂,所述转向臂外部包裹有定位套筒。该发明通过在转向驱动桥和转向臂连接的位置外部,螺接有定位套筒,定位套筒内部通过弹簧连接有定位板,定位板贴合在转向臂外壁,当转向臂在运行时,通过定位板和弹簧可与转向驱动桥之间起到更好的稳定定位性能;同时,在当万向传动装置外部设置有保护壳,保护壳内部设置有润滑管道,润滑管道内的润滑液可循环式的注入传动槽内,从而减少传动槽和传动球之间的摩擦,延长装置的使用寿命。
