Abstract

The invention relates to the field of rail vehicle gauge change, and discloses a gauge change wheel set, the wheels of which include a wheel body, the inner side of the wheel body is provided with an inner wheel hub extending inward, and the inner wheel hub is used for installation and locking Mechanism, the outer side of the wheel body is provided with an outer hub extending outward, and the outer hub is used for installing a transverse driving mechanism. The wheel of the invention has compact structure and high space utilization rate, and can adapt to the form of active gauge change, and the gauge change wheel set can improve the reliability of gauge change and the efficiency of track change.

Description

technical field [0001] The invention relates to the technical field of gauge changing for rail vehicles, in particular to a gauge changing wheel set. Background technique [0002] In order to meet the transportation requirements between tracks of different gauges in neighboring countries, bogies with different inner distances of wheel sets are often replaced at the junction. This solution is costly and time-consuming. Spain and Japan successively invented variable-gauge bogies, which can run continuously between tracks of different gauges. [0003] However, the existing track-changing structures are all passive forms, and the track-changing action can only be completed with the help of external auxiliary facilities, which has low efficiency, and the existing wheel structure can no longer adapt to the active gauge-changing form. Contents of the invention [0004] (1) Technical problems to be solved [0005] The present invention aims to solve at least one of the technical...
