CRH5型动车组牵引传动系统故障解析及维护保养

The Fault Interpretation and Maintenance of the Traction Drive System for CRH5 Multiple-unit Train

动车组传动系统为动车组的动力传输装置,CRH5型动车组牵引传动装置区别于其他高速动车组传动系统,独具特点。CRH5型动车组牵引传动系统由牵引电机、万向轴、齿轮箱三大部件组成。牵引电机产生的牵引力通过万向轴及齿轮箱传导至车轮上,最终产生了牵引作用。本文通过牵引系统常见故障的分析,研究出可行性的预防方法,可以有效地规避动车组运行风险。

The drive system is the power transfer unit for multi- ple-unit trains. The traction drive system of CRH5 multiple-unit train differs from the drive system of other multiple-unit trains and has its own features. The traction and drive system of CRH5 multiple-unit train consists of such three major parts as traction motor, cardan shaft and gear ease. The tractive force produced by the traction motor is transferred to the wheels through the eardan shaft and gear ease, finally generating the function of traction. By analyzing eommon faults in the traction system, this paper studies feasible prevention methods which can effectively avoid the risks in the working of multiple-unit trains.
