Background technique [0002] The superconducting electric magnetic levitation vehicle (EDS) generally adopts the side wall type suspension. The ground suspension guide coil and the ground propulsion coil are arranged on the two side walls of the U-shaped track, and the superconducting magnets are arranged on both sides of the suspension frame. The magnetic field generated by the ground propulsion coil It acts with the superconducting magnet to drive the vehicle to run, and the magnetic field generated by the superconducting magnet cuts the ground suspension coil to form an induced current and an induced electric field, and relies on the interaction between the induced electric field and the superconducting magnet to achieve...

Problems solved by technology

[0005] First, the Dewar outside the superconducting magnet suitable for the whole vehicle is generally 5 to 6 meters long, and a series of springs are arranged at the front and rear ends of the top respectively. The load of the whole vehicle is first transmitted to the outer Dewar of the superconducting magnet, and then Inwardly transmitted to the coil of the superconducting magnet, that is, the outer Dewar of the superconducting magnet bears the concentrated load of the whole vehicle; therefore, the strength and stiffness of the outer Dewar are extremely high, resulting in a large mass of the superconducting magnet, which often occupies the entire suspension frame. 50% or more of the mass, and this part of the mass is the unsprung mass, the increase in mass is extremely detrimental to the dynamic performance of the maglev vehicle and the comfort during normal driving

[0006] Second, the superconducting magnet cannot generate sufficient electromagnetic levitation force and guiding force when running at low speed. At this time, the superconducting magnet needs to be safely supported on the suspension frame when it is supported by the landing gear and guide wheels. The first series of springs in the above patent are Air springs, air springs are basically unable to bear the tension, so the first series of springs cannot elastically hang the superconducting magnet, resulting in the inability to support the superconducting magnet stably and safely when the vehicle is running at low speed; in addition, only relying on rigid brakes to support the superconducting magnet at low speed will Causes excessive vibration, resulting in poor comfort when superconducting electric magnetic levitation vehicles run at low speeds
