The invention discloses an anti-eccentric-wear brake-shoe clearance adjusting device and a mounting method, relates to the technical field of brake-shoe clearance adjustment, solves the problem of brake-shoe eccentric wear caused by small brake-shoe clearance when a bogie is relieved, optimizes a stress structure, avoids deterioration of the condition of brake-shoe eccentric wear, and improves the service life of the bogie. According to the specific scheme, the device comprises two brake beam assemblies which are oppositely arranged, four brake shoe holders are symmetrically hinged to the two ends of the two brake beam assemblies, each brake shoe holder is provided with a rotating brake shoe hanging rod, and the two brake shoe holders on the same side are connected through two elastic force adjusting mechanisms which are arranged in a crossed mode; an upper spring hanging seat and a lower spring hanging seat which are used for being connected with an elastic force adjusting mechanism are fixedly installed on each brake head, the upper spring hanging seats and the brake heads are installed and welded on the two sides of a brake-shoe hanging rod, and the lower spring hanging seats are welded on the outer sides of brake beam sleeves of the brake heads.
本发明公开了一种防偏磨的闸瓦间隙调整装置及安装方法,涉及闸瓦间隙调整技术领域,解决了转向架缓解时闸瓦间隙较小导致闸瓦偏磨的问题,优化了受力结构,避免了闸瓦偏磨的情况恶化,具体方案如下:包括两个相对设置的制动梁组成,两个制动梁组成的两端对称铰接有四个闸瓦托,每个闸瓦托上安装一个转动的闸瓦吊杆,同侧的两个闸瓦托之间通过两个交叉设置的弹力调整机构连接,每个闸瓦托上固定安装有一个用于与弹力调整机构连接的上弹簧吊座和下弹簧吊座,所述上弹簧吊座与闸瓦托组焊于闸瓦吊杆的两侧,下弹簧吊座焊接于闸瓦托的制动梁套筒的外侧。
