Abstract

The invention relates to the field of rail vehicle gauge change, and discloses a gauge change wheel set and a gauge change bogie, including wheels, axles, locking mechanisms and lateral drive mechanisms, the wheels and axles are connected by splines, and the axles are located on the wheels The outer two ends are respectively supported in the axle box; the locking mechanism is respectively arranged on the inner side of each wheel, the locking mechanism includes a traction electromagnet, the traction electromagnet includes a traction coil and a moving iron core driven by the traction coil, and the wheel A plurality of locking holes are arranged at intervals along the axial direction on the inner hub of the inner wheel, and the moving iron core can extend into or leave the locking holes to realize wheel locking or unlocking; the lateral driving mechanism is respectively arranged on the outer side of each wheel and fixed on the On the axle box body, the transverse driving mechanism includes an electric cylinder, and the protruding end of the electric cylinder is used to push or pull the unlocked wheel to realize wheel gauge change. The invention can reduce the abrasion between wheel axles, improve the reliability of track gauge change, and improve the track change efficiency.

Description

technical field [0001] The invention relates to the technical field of gauge-changing rail vehicles, in particular to a gauge-changing wheel set and a gauge-changing bogie. 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 orbit-changing structures are all passive, and the orbit-changing action can only be completed with the help of external auxiliary facilities, and the efficiency is low. Contents of the invention [0004] (1) Technical problems to be solved [0005] The present invention aims to solve at least one of the technical problems existing in the prior art or related art [0006] The purpo...
