The invention provides a device which is provided with a transnational train and used for changing the track gauge, in particular to a variable-track-gauge wheel which is simple in structure and convenient to operate. The wheel comprises a shaft, wheel bodies and movable wheel hoops; the two ends of the shaft are connected with the wheel bodies; the width of hubs of the wheel bodies are larger than that of a traditional wheel hub; the width increment is half of the difference between a maximum track gauge and a minimum track gauge; the movable wheel hoops with the thicknesses different from those of the hubs are added to the hubs and are each formed by connecting two semi-circular rings through bolts; an inner hole of each movable wheel hoop and the corresponding hub are in interference fit; the portion, at one end of each movable wheel hoop, of the corresponding inner hole is provided with a groove which is buckled to an original wheel hoop of the corresponding wheel body; the end face of the other end of each movable wheel hoop is matched with the arc angle of a track; the thickness of each movable wheel hoop is half of the difference between the two different track gauges; different track gauges can be formed by converting the movable wheel hoops of different thicknesses. The variable-track-gauge wheel can change the track gauge in the running way of the transnational train and meet the requirement of different countries for track gauge differences.
