The invention designs a threaded ratchet steel sleeve for mounting a triangular arm ball pin. The sleeve is characterized by comprising a body in a hollow column shape; the inner wall of the body is provided with an internal thread matched with the ball pin; one end face of the body is provided with a limiting table with the outer diameter larger than that of the body, and the limiting table and the triangular arm are positioned; and a plurality of strip-shaped protrusions are arranged on the outer wall of the body at intervals. The threaded ratchet steel sleeve (the material strength is equivalent to the material strength of the ball pin) is additionally arranged between the triangular arm and the ball pin which are made of an aluminum material, the strength of internal threads of the triangular arm is indirectly improved, the cost of the triangular arm is reduced, the service life of the triangular arm is prolonged, meanwhile, the risk that the connecting threads of the triangular arm and the ball pin fall off and loosen is reduced, and the reliability of the triangular arm is improved; and the additional arrangement of the threaded ratchet steel sleeve does not change the original connection mode of the triangular arm and the ball pin, and meanwhile, the threaded ratchet steel sleeve and the triangular arm are reliably connected and do not cause the failure problem.
本发明设计的用于三角臂球头销安装的螺纹棘齿钢套,其特征在于:包括本体,所述本体为中空柱状;所述本体内壁设有与球头销适配的内螺纹;所述本体其中一端面设有外径大于本体外径的、与三角臂定位的限位台;所述本体外壁间隔设有多个条形凸起。在铝材质的三角臂和球头销之间增加螺纹棘齿钢套(材质强度与球头销材质强度相当),间接地提升了三角臂内螺纹的强度,降低了三角臂的成本及提升了三角臂的寿命,同时也降低了三角臂与球头销连接螺纹掉扭和松脱的风险,提升了三角臂的可靠性;螺纹棘齿钢套的增加不会改变原有三角臂和球头销的连接方式,同时螺纹棘齿钢套与三角臂连接可靠不会引起失效问题。
