Abstract

The invention provides an electromagnetic levitation train track system, tracks are arranged on two sides of a roadbed or a track beam, a magnetic levitation train runs on the tracks, the system is characterized in that traction guide electromagnets are horizontally arranged on supporting arms on two sides of the magnetic levitation train, and linear motor stators are horizontally arranged at opposite positions on the tracks, a linear motor stator and a traction guide electromagnet are horizontally arranged in the magnetic pole direction, an iron core linear motor is formed by the linear motorstator and the traction guide electromagnet at a certain magnetic gap, and an E-shaped section suspension electromagnet and a gap sensor are arranged at the bottom of the maglev train and suspended below an armature plate horizontally arranged at the bottom of a rail. The control system controls the current and direction of the traction guide electromagnet and the linear motor stator coil, and controls the horizontal guide and suspension force and the traction force and direction, so that the maglev train flies in the air.

Description

technical field

[0001] The invention belongs to the field of rail transportation, and in particular relates to an electromagnetic levitation train track system, which is suitable for a high-speed flying magnetic levitation train track system and a vacuum pipeline magnetic fly train. Background technique

[0002] Typical electromagnetic levitation trains that have been put into commercial operation include Germany's EMS system and Japanese superconducting electric levitation trains, and medium and low-speed maglev trains in Japan, China and South Korea. The main problems in the existing technology are: the electromagnetic levitation system of the EMS magnetic levitation train system is not only a levitation electromagnet but also a linear motor traction motor is not very efficient, the load capacity is weak, and there is a synchronous linear motor with a large weight and a traveling wave magnetic field. The traction control structure is complicated. There is obvious electrom...
