Title:
MAGLEV TRAIN AND MOVING PART THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/062121
Kind Code:
A1
Abstract:
A moving part of a maglev train, comprising two levitation frames (1) that are arranged at an interval along the direction of travel, the two levitation frames (1) being connected by means of a vertical beam (2); a peripheral wall of the vertical beam (2) is provided with a slot (21) that may reduce the torsional rigidity thereof, being capable of reducing the torsional rigidity of the traditional vertical beam (2) so as to reduce the coupling effect between the two levitation frames (1) that are connected by means of the vertical beam (2), thereby greatly reducing the difficulty and energy consumption of levitation control. The levitation frames (1) and a train body are connected by means of air springs (13) having large horizontal and vertical displacement, flexibly supporting the train body while also being capable of greatly simplifying a traditional secondary suspension structure, thus reducing the weight of the moving part. The levitation frames (1) and the train body are provided therebetween with a vertical shock absorber (19) and a horizontal absorber (18) having suitable damping values, being used to attenuate the vibrations of the train body and improve the stability and comfort of the train during operation; furthermore, the levitation frames and the train body are provided therebetween with horizontal stoppers (171a) and vertical stoppers (172a), which may prevent excessive horizontal movement, rollover and overturning. Further disclosed is a maglev train comprising the moving part.
