The high-temperature superconducting maglev train comprises a frame, holding arms, Dewars, superconductors, permanent magnet tracks, iron cores, coils and power supplies, wherein the holding arms are arranged on the side face of the bottom of the frame, the Dewars are arranged at the bottom of the frame, the superconductors are arranged in the Dewars, the permanent magnet tracks are arranged below the Dewars, the iron cores are arranged below the permanent magnet tracks, the coils are arranged on the iron cores in a sleeving manner, and the positive electrodes and the negative electrodes of the power supplies are connected with two ends of the coils respectively.According to the high-temperature superconducting maglev train, levitation and guiding functions are achieved through the superconductors and the upper surface magnetic fields of the permanent magnettracks, a driving function is achieved through the lower surface magnetic fields of the permanent magnet tracks and the electrified coils, the maglev train achieves the levitation-guiding and drivingfunctions through the same permanent magnet tracks, the cost is saved, the magnetic energy utilization rate of the permanent magnet tracks is increased.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a superconducting maglev train. Background technique [0002] At present, it is known that the traditional superconducting maglev train uses the diamagnetism and lateral stability of the superconductor in the superconducting state to form a force on the magnetic track, so that the train has a levitation-guiding function, and then it is driven by an independent motor. Relatively speaking, the integration of levitation, guidance and drive of traditional superconducting maglev trains is not high. In addition, the independent motor uses an independent winding track-laying type and a permanent magnet track-laying linear motor, which needs to lay a permanent magnet track or an excitation track on the track, which is relatively expensive; and the magnetic field on the lower surface of the track is not can be applied, the utilization rate of the magnetic field energy of the entire ...
