摘要
以SS4型电力机车为例,通过对抱轮式单元制动器闸瓦在闸瓦托中的受力分析以及对在用机车闸瓦使用情况的普查,得出了闸瓦钎孔断的原因,给出了相应的整顿措施。
Taking SS4 electric locomotive as an example,the reasons of brake shoe bit hole breaking is obtained by analyzing the force of brake shoe in brake shoe support of holding-wheel type unit and surveying the usage of brake shoe of locomotive in use,and the corresponding rectification measures are given.
