Magnetic levitation railway vehicle and bogie thereof

Abstract

The invention discloses a magnetic levitation railway vehicle and a bogie thereof. The bogie comprises a frame composed of a lateral beam and a transverse beam, a plurality wheelset shaft box device below the frame, a plurality of guide devices installed on the outer side of the lateral beam of the frame, a first-stage suspension device, a second-stage suspension device, a traction device used for being installed between the inner side of the transverse beam of the frame and a vehicle body, and a transverse stop dog. An anti-disengaging and hoisting device is installed between the inner side of the lateral beam of the frame and the vehicle body. A foundation braking device is installed between the bottom of the transverse beam of the frame and an axle of the wheelset shaft box device. The bogie can adapt to running of medium-speed and low-speed magnetic levitation railway vehicles, and the moving problem of the medium-speed and low-speed magnetic levitation railway vehicles on tracks is solved.

Description

technical field [0001] The invention relates to a maglev rail vehicle and its bogie, belonging to the field of maglev rail vehicles. Background technique [0002] Engineering vehicles play an important role in track construction, line maintenance and inspection operations, and are necessary supporting facilities to ensure efficient and safe operation of operating vehicles. In the medium and low-speed maglev transportation system, operating vehicles rely on electromagnetic attraction to suspend on the track and do not touch the track; because engineering vehicles cannot rely on track power supply, they must adopt a different track cooperation method than operating vehicles. In addition, the medium and low speed maglev track is completely different from the traditional railway track, and the bogie of the medium and low speed maglev engineering vehicle cannot follow the bogie of the traditional railway vehicle. The Shanghai high-speed maglev engineering vehicle is transformed ...

AI Technical Summary

Problems solved by technology

Some existing medium and low-speed maglev transportation systems have relatively simple structures for maintenance devices and maintenance equipment running mechanisms, so their working efficiency is low, their carrying capacity is insufficient, and their long-distance operation capacity is limited, which cannot meet the maintenance work of medium and low-speed maglev commercial lines.
