摘　　要：制动器零部件在后市场的使用过程中不同状态之间的装配组合形式繁多,这会带来潜在的制动舒适性问题,而制动抖动则是抱怨率较高的问题之一。本文从后市场某畅销车型反馈的抖动问题出发,通过道路测试复现了抖动发生的现象,获取了抖动发生的条件,并对制动系统拆解和分析,发现制动拖滞是主要原因。在不对原制动系统做较大变更的前提下,提出了制动片新增回位卡簧优化方案,测试结果表明,回位卡簧有效改善了拖滞引起的制动抖动问题。The different brake parts status between assembly combination is various in the using process of the aftermarket.It will bring potential brake comfort problem,while braking judder is one of the highest complaint issues.Starting from the feedback of a popular vehicle in the aftermarket,this paper reproduces the phenomenon and test conditions through road tests.And the main reason is the brake drag by brake system disassembly and analysis.Then,the optimization of brake pad is put forward by using the return spring.The comparison test results show that the return circlip has a remarkable effect on the brake judder caused by brake drag.
