摘要
城市轨道交通车辆运行中,转向架轮对与钢轨接触、摩擦,造成轮缘与钢轨磨耗,产生轮轨噪声。为减小轮轨磨耗,在部分车辆的拖车一位端转向架安装有轮缘润滑装置,可有效解决轮对与钢轨的干摩擦问题,极大减缓轮缘磨耗、减小轮轨噪声、延长车轮使用寿命。
During the operation of urban rail transit vehicles,the contact and friction between bogie wheel sets and steel rails cause the wear of wheel flanges and steel rails,resulting in wheel rail noise.In order to reduce wheel rail wear,wheel flange lubrication devices are installed on the bogies at the trailer end of some vehicles.The wheel flange lubrication device can effectively solve the problem of dry friction between wheel pair and rail during rail vehicle operation,greatly reduce the wear of wheel flange,reduce wheel rail noise and prolong the service life of wheel.
