Abstract

The invention relates to the field of rail vehicle gauge changing, and discloses a transverse driving mechanism for a gauge-changeable wheel set and the gauge-changeable wheel set. The transverse driving mechanism is respectively arranged on the outer side of each wheel and fixed to an axle box body; the transverse driving mechanism comprises an electric cylinder, and an extending end of the electric cylinder is used for pushing or pulling the unlocked wheel to achieve gauge changing of the wheel. The wheels are actively pushed or pulled through the transverse driving mechanisms, so transversemoving of the wheels is achieved, the transverse moving of the wheels is more stable, abrasion between axles can be reduced, and the reliability of gauge changing is improved.

Description

Technical field [0001] The invention relates to the technical field of rail vehicle gauge changing, in particular to a transverse drive mechanism for a gauge changing wheel set and 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 wheelset inner pitches are often replaced at the junctions. This solution is costly and time-consuming. Spain and Japan have invented variable gauge bogies, which can run continuously between tracks with different gauges. [0003] However, the existing orbit-changing structures are all passive, and the orbit-changing action needs to be completed with external auxiliary facilities, and the efficiency is low. Summary 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 technologies. [0006] Th...
