ZHOU Dianmai, HUANG Zhihui, XU Bin, et al. Wear Analysis of Wheel Shaft in Typical Gauge Changeable Bogies Abroad[J]. Electric Drive for Locomotives, 2018,(6):42-45.
Gauge changeable bogie technology has been successfully applied abroad, and problems such as axle wear and short service life of sliding bearings have appeared in the course of operation. The problems, causes and solving measures of gauge changeable bogies in Japan and Poland were introduced in detail. The characteristics and wear condition of gauge changeable bogies in Spain were analyzed. A feasible way to solve the problem of wheel axle wear in the development of gauge changeable bogies in China was put forward.
