This paper briefly introduces the various measures adopted to overcome the differences in track gauge and its characteristics, and points out that the use of variable gauge wheels is an effective method for the technology. The status quo of existing variable gauge wheelsets in foreign countries is summarized. The key points and key points of the wheel gauge gauge technology in railway vehicles are analyzed in detail. A new variant of gauge gauge wheelset is proposed
