Abstract
A moving part of a maglev train, comprising two levitation frames that are arranged at an interval along the direction of travel, the two levitation frames being connected by means of a vertical beam; a peripheral wall of the vertical beam provided with a slot that may reduce the torsional rigidity thereof, being capable of reducing the torsional rigidity of the traditional vertical beam so as to reduce the coupling effect between the two levitation frames that are connected by means of the vertical beam, thereby greatly reducing the difficulty and energy consumption of levitation control. The levitation frames and the train body are provided therebetween with a vertical shock absorber and a horizontal absorber having suitable damping values, the levitation frames and the train body are provided therebetween with horizontal stoppers and vertical stoppers which may prevent excessive horizontal movement, rollover and overturning.
