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

Abstract

The invention discloses a three-wire rail-holding high-speed maglev train system. A stator track line is mounted in the middle line of an inverted E-shaped long track; and long stators of left and right linear motors are arranged. A left magnetic levitation track line and a right magnetic levitation track line on two sides of the inverted E-shaped long track are long stators of a left resultant force magnetic levitation device track and a 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 forcemaglev device racks of the high platform support two sides of the maglev train; the train center of gravity is low, the magnetic levitation control system of whole vehicle is simple, the height of theloaded automatic stable magnetic levitation adapt to the train is 10mm, the system is compatible with control over a whole train brake, a conventional braking system is omitted, six rail holding faces are arranged on each of a front rail holding bogie and a rear rail holding bogie of the three-wire rail-holding high-speed maglev train system, so that the high-speed maglev train cannot derail andis safe and reliable.

Description

Technical field [0001] The invention relates to maglev train technology, in particular to a three-line rail-holding high-speed maglev train system. technical background [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 R&D to application, and becoming one of the few countries in the world that have mastered this technology. However, compared with the wheel-rail high-speed trains in the prior art, the advantages of medium and low-speed maglev trains are not prominent, the cost is high, and the practical value is not comparable to that of mature high-speed trains. However, due to the limitation of wheel resistance, The speed of high-speed trains can't be further improved, so it's the ideal goal for people to strive to realize high-speed maglev trains. At present, the prior art high-speed maglev trains in the world are composed of a maglev system, a...

[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
