Problems solved by technology

[0005] 1. This traction method cannot meet the high-efficiency operating speed (the maximum operating speed is only about 100 kilometers per hour)
[0006] 2. The motor coils using this traction method must be installed on the vehicle, and must be equipped with vehicle-mounted traction equipment such as high-voltage circuit systems, filter reactors, traction inverters, linear motors, and braking resistors. The traction equipment is complex
[0007] 3. In practical applications, the safe operation of the train requires a suspension gap of about 8mm between the vehicle and the track. Since the motor must not touch the track when the vehicle lands, and there are installation errors between the track

Abstract

The invention discloses a track component for a maglev train. The track component comprises a track, a bogie arranged on a maglev train body, a traction module, and levitation guide modules arranged on two sides of the track. The traction module is disposed in the middle of the track and comprises array structured permanent magnets in corresponding arrangement and a long stator coil; power supply is controlled for the long stator coil via the ground; the array structured permanent magnets are mounted on the bogie; the long stator coil is mounted on the track; the long stator coil and the array structured permanent magnets interact to produce tractive force for the maglev train. The track component has the advantages that utilization rate of energy resources is increased, energy consumption is lowered and vehicular equipment is simplified.

Description

technical field [0001] The invention relates to the field of maglev trains, in particular to a track assembly suitable for a maglev train. Background technique [0002] The maglev train is a rail vehicle that uses electromagnetic force to realize the non-contact support and guidance of the train, and realizes non-contact traction and braking through linear motors. At present, relatively mature maglev trains include low-speed maglev trains and high-speed maglev trains, which have three basic functions of suspension, guidance and traction. Suspension refers to the non-contact between the maglev train and the track, and guidance is to realize the steering and anti-rolling of the maglev train. Traction is to realize the forward moving function of the maglev train. [0003] The traction of low-speed maglev trains adopts asynchronous induction mode, which has the advantages of simple structure, small turning radius and low noise. Its suspension (guiding) and traction components ...
