通过对货车转向架结构及零部件装配关系和轮位差传统的测量方法的分析,提出了轮位差的测量应以轴肩为基准;介绍了一种新型铁道车辆轮对轮位差测量尺。

After analyzing the railway freight car bogie structure, the assembly relationship of the parts and the traditional method used to measure the positioning errors of wheel, the author suggests that the shaft neck should be the datum when positioning errors of wheel is measured.
