The invention discloses a method for improving abnormal sound of a steering column, and belongs to the technical field of steering systems. According to the method for improving the abnormal sound of the steering column, the first sensitive area prone to being abraded in the early stage and the second sensitive area prone to being abraded in the later stage in the long-time use process of the steering column are determined through the durability test, the first sensitive area is processed through laser, the first micro-groove morphology is formed, and the abnormal sound of the steering column is improved. According to the method, the first sensitive area is formed, the second sensitive area is processed through laser, the second micro-groove morphology is formed, in other words, different laser micro-modeling morphologies are designed for different sensitive areas, the tribological characteristics of the different sensitive areas can be improved, the lubricant storage capacity of the different sensitive areas can be improved, and the lubricant storage capacity of the different sensitive areas can be improved. The storage capacity of different sensitive areas on abrasive particles is improved, so that the loose abnormal sound caused by long-time abrasion of the worm gear and the worm is obviously improved; compared with the prior art, other components do not need to be added, and the structural complexity of the steering system cannot be increased.

    本发明公开了一种改善转向管柱异响的方法,属于转向系统技术领域。本发明的改善转向管柱异响的方法,通过耐久试验,确定转向管柱在长时间使用过程中容易在前期出现磨损的第一敏感区域和容易在后期出现磨损的第二敏感区域,利用激光对第一敏感区域进行处理并形成第一微凹槽形貌,并利用激光对第二敏感区域进行处理并形成第二微凹槽形貌,换言之,针对不同敏感区域设计不同的激光微造型形貌,不仅能够改善不同敏感区域的摩擦学特性,还能够提高不同敏感区域对润滑剂的存储能力,以及不同敏感区域对磨粒的存储能力,进而使蜗轮蜗杆因长时间磨损导致的松旷异响得到明显改善;相比于现有技术,无需增加其他部件,不会增加转向系统的结构复杂程度。
