AI Technical Summary
When existing rail vehicles change between different track gauges, they need to replace the bogies or use complex variable gauge bogies, resulting in low operating efficiency, high costs, and high dependence on ground facilities.
It adopts a continuously variable track wheelset, integrating the track variable motor inside the wheelset. The track variable stator and track variable rotor are screwed together, and the motor drives the wheel to move axially. Combined with distance sensors and control modules, it can achieve precise track gauge adjustment and reduce dependence on ground facilities.
It enables stepless adjustment of track gauge within the structural travel range, improving track compatibility, simplifying mechanical structure, and reducing failure rate and construction and maintenance costs of ground facilities.
