The invention discloses a joint based on a steering pull rod of an automobile steering system, and relates to the technical field of automobile parts. The joint comprises a ball seat, wherein a ball head is rotatably connected into the ball seat, a ball head pin penetrating through the ball seat and extending out of the ball seat is fixed to the ball head, a shaft hole is transversely formed in the bottom of the outer circle face of the ball seat, and connecting sleeves matched with the shaft hole are fixed to the positions, located at two ends of the shaft hole, of the outer circle face of the ball seat; and a connecting rod matched with the shaft hole transversely penetrates through the ball seat. The ball head pin is sealed layer by layer through multiple sealing pieces, external dust or foreign matters can be effectively prevented from entering the ball head pin, abrasion between the ball heat seat and the ball head pin is reduced, the overall use performance of the joint is guaranteed, and the service life of the joint is prolonged; and by using the layer-by-layer sealing pieces, the ball head and the ball head pin can be effectively limited, the displacement of the ball headpin in the ball head seat is reduced, and the steering precision and the running stability of an automobile are improved.
本发明公开了一种基于汽车转向系统转向拉杆的接头,涉及汽车零部件技术领域。本发明包括球座,球座内部转动连接有球头,球头上固定有贯穿球座且延伸至球座外部的球头销,球座外圆面底部横向开设有轴孔,球座外圆面上且位于轴孔两端的位置均固定有与轴孔配合的连接套管,球座上横向贯穿有与轴孔配合的连接杆。本发明多个密封件层层对球头销进行密封,能够有效的避免外界灰尘或异物的进入,减少了球头座与球头销之间的磨损,保证了接头总体的使用性能,提高了接头的使用寿命;并且通过层层密封件的使用,能够有效的对球头和球头销进行限位,减小球头销在球头座内的位移量,提高转向精度和汽车行驶的稳定性。
