technical field [0001] The invention relates to the technical field of rail transportation, in particular to a permanent maglev train rail system, especially for medium and low-speed subways and urban rapid rail transit systems, and vacuum pipeline ultra-high-speed trains and rail systems. Background technique [0002] The main problems existing in the prior art are: the EMS electromagnetic levitation system and the electromagnetic guidance system require complex active control systems, the weight of the train is high, the energy consumption is high, and the structure is complex. The superconducting electric levitation train adopts the low-temperature superconducting system to levitate, which has obvious electromagnetic radiation, and the structure is more complicated.

Problems solved by technology

[0002] The main problems in the existing technology are: EMS electromagnetic levitation system and electromagnetic guidance system require complex active control system, the weight of the train is high, energy consumption is high, and the structure is complex

The superconducting electric levitation train adopts the low-temperature superconducting system to levitate, there is obvious electromagnetic radiation, the structure is more complex, and at the same time, rubber wheels are needed for support at low speed, and the cost is higher

Medium and low-speed maglev trains are simple in structure, but the energy consumption of suspension is high. Linear asynchronous induction motors are used. Copper or aluminum plates are laid on the top surface of the track and the driving efficiency of asynchronous motors on the bottom of the train is very low.

[0003] The wheel-rail train has a simple structure and a long history of application, but the open wheel-rail structure may cause potential safety hazards of derailment at any time. In addition, the wheel bearings are severely worn under high speed and heavy loads, requiring frequent replacement and maintenance, high energy consumption, and low service life. The adhesion coefficient is low at high speed, and the transmission and deceleration are difficult. Although the one-time infrastructure cost is low, the later operation and maintenance cost is high
