Gear traction high-speed maglev train system

Abstract

The invention discloses a gear traction high-speed maglev train system. A multifunctional long rail is mounted in the middle line of a horizontally-arranged-E-shaped long rail; the multifunctional long rail integrates a left transmission long rack, a right transmission long rack and a long-strip-shaped brake plate, so that positioning of a gear transmission mechanism, a strip-shaped plate brakingmechanism and resultant force magnetic levitation device tracks is accurate; the mechanisms are stable and reliable; a left and right long high platforms are arranged on the left and right resultant force maglev device tracks to support two sides of the maglev train, so that the gravity center of the maglev train is low and the safety of the maglev train high; the height of magnetic levitation isautomatically adjusted according to the load capacity of the train, a complex magnetic levitation control system is omitted; a plurality of high-speed electric gear traction systems replace an expensive linear motor driving system; a plurality of high-speed electric gears and left and right transmission long racks are in meshing transmission to float up and down along with a bogie, do not bear thegravity of the train, and therefore, traction efficiency is high.

Description

technical field [0001] The invention relates to the magnetic levitation train technology, specifically, a gear traction high-speed magnetic levitation train system. Background technique [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 maglev train sch...

[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 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 systems are basically realized by the use of magnetic force. Yes, the scheme of using electromagnetic technology for the three major systems of the maglev train is not perfect. Its disadvantages are: the electromagnetic control technology is complicated and the cost is high, especially the long stator of the linear motor, the cost is very high, the working magnetic field is not closed, the reliability is poor, and The efficiency of the motor is not high. Therefore, realizing economical, safe and practical high-speed maglev trains is the development direction of maglev trains in the future.
