Three-wire rail holding type high-speed maglev train system

Abstract

The invention discloses a three-wire rail holding type high-speed maglev train system. A stator track line is mounted in the middle line of the E-shaped long track; the stator is a long stator of leftand right linear motors. A left magnetic levitation track line and a right magnetic levitation track line on two sides of the E-shaped long track are long stators of the left resultant force magneticlevitation device track and the right resultant force magnetic levitation device track; the working surfaces of the three track lines are all downward; the problems of water accumulation, sediment accumulation and garbage accumulation do not exist; when the high-speed left and right linear motors operate at high speed, the traction efficiency is high, the left and right resultant force maglev device rails of the high platform support two sides of the maglev train to enable train center of gravity to be low, magnetic levitation control system of whole vehicle is simple, the high-speed maglev train system adapts to the load of a train, the automatic stable maglev height is 10 mm, control over a whole train brake can be compatible, a conventional braking system is omitted, six rail holding faces are arranged on each of the front rail holding bogie and the rear rail holding bogie of the three-wire rail holding type high-speed maglev train system, and thus the high-speed maglev train cannot derail and is safe and reliable.

[0002] At present, China's medium and low-speed maglev trains have been successfully tested and started commercial operation, realizing the full coverage of China's maglev trains from research and development to application, becoming one of the few countries in the world that have mastered this technology, but medium and low-speed maglev trains Compared with the wheel-rail high-speed train of the prior art, the advantages of the train are not outstanding, the cost is very high, and the practical value is not as good as that of the mature high-speed train. However, due to the limitation of the wheel resistance, the speed of the high-speed train cannot be further increased, so Efforts to realize the high-speed maglev train is the ideal goal that people pursue. At present, the high-speed maglev train scheme of the existing technology in the world is composed of a maglev system, a guidance system and a traction system. The technical schemes of the three major systems basically use long tracks. The magnetic force between the stator and the mover of the train is realized. The high-speed maglev train of the prior art is generally a single-track rail type. The disadvantage is that the working air gap between the stator of the long track and the mover of the train is exposed to the Outside, the working surfaces of the three major systems cannot be closed, especially the working surfaces of the three major systems are not all facing downwards, and the long track with the working surface facing upwards tends to accumulate water, silt, and garbage, so cleaning devices must be added. Otherwise, the reliability and safety will be worse. In addition, the maglev control system is complex and cannot be controlled compatible with the braking control system, which will increase the cost of the vehicle control system. Therefore, realizing economical, safe and practical high-speed maglev trains is the goal of maglev trains in the future Direction of development
