The invention relates to a steering gear bushing assembly, and belongs to the technical field of automobile steering. The steering gear bushing assembly comprises a bushing and a special-shaped sealing ring, a special-shaped sealing ring is sleeved on the outer surface of the bushing; a plurality of upper expansion joints are uniformly formed in the circumferential surface of the special-shaped sealing ring; the upper end of the upper expansion joint is open; lower expansion joints are arranged on the rectangular sealing ring between the adjacent upper expansion joints; and the lower end of the lower expansion joint is open. The steering gear bushing assembly is compact in structure and ingenious in design, and the structural design that the special-shaped sealing ring is arranged on the outer side of the bushing in a sleeving mode is adopted; by adopting the design, the special-shaped sealing ring is in surface contact with the contact surface of the main hole of the shell, so that the problem of abnormal sound caused by relatively small bearing radial rigidity when the existing bushing is in contact with the main hole of the shell through the sealing ring is solved, and the special-shaped sealing ring is particularly suitable for the use requirement of an automobile steering device.

    本发明涉及一种转向器衬套总成,属于汽车转向技术领域。该转向器衬套总成,包括衬套和异形密封圈;所述的衬套外表面套装有异形密封圈;所述的异形密封圈的圆周面上均匀设置有多个上伸缩缝;上伸缩缝的上端呈开口状设置;所述相邻上伸缩缝之间的矩形密封圈上设置有下伸缩缝;下伸缩缝的下端呈开口状设置。该转向器衬套总成,结构紧凑、设计巧妙,采用了在衬套外侧套装异形密封圈的结构设计;采用该种设计后异形密封圈将与壳体主孔接触面呈面接触,由此解决了现有衬套通过密封圈与壳体主孔接触时存有的承载的径向刚度相对较小而导致异响的问题,特别适合汽车转向器使用的需要。
