A kind of pipeline type maglev train

Abstract

The invention discloses a pipeline type magnetic suspension train. The pipeline type magnetic suspension train comprises a suspension device, a guiding device, a driving device, a running device, a current collecting device and a pipeline device. The suspension device is composed of a downward moving magnetic levitation body and a downward fixing magnetic levitation plate; the guiding device is composed of a left moving magnetic levitation body, a left fixing magnetic levitation plate, a right moving magnetic levitation body and a right fixing magnetic levitation plate; the driving device comprises a stator and a rotor permanent magnet; the running device is composed of a left guide wheel, a left guide rail, a right guide wheel and a right guide rail; and the pipeline device is composed ofa pipeline, a left frame, a right frame, a top frame and a wheel-rail support boss. According to the pipeline type magnetic suspension train, a passive suspension technology is adopted, and a train is suspended only by the magnetic repulsion force formed by the relative movement between the downward moving magnetic levitation body and the downward fixing magnetic levitation plate, so that self-stable suspension is realized. According to the pipeline type magnetic suspension train, complex and expensive control systems are not needed, only the coil winding current in the stator need to be controlled, and the current control technology in the stator is mature and the price is relatively low.

Description

technical field [0001] The invention relates to a magnetic levitation train, in particular to a pipeline type magnetic levitation train. Background technique [0002] Hyperloop is a means of transportation based on the theory of "vacuum steel pipe transportation", which has the characteristics of ultra-high speed, high safety, low energy consumption, low noise, and low pollution. [0003] At present, the American electric vehicle company Tesla and the American technology company ET3 have announced the "vacuum steel tube transportation" plan. Tesla named it "Hyper High Speed ​​Rail". . [0004] The tube-type maglev train "floats" in a vacuum tube. Since the operating space is vacuum and there is no friction, the train's running speed may reach a maximum of 5,000 kilometers per hour. [0005] Existing maglev trains are generally divided into three types: conventional maglev trains, low-temperature superconducting maglev trains and high-temperature superconducting maglev trai...

AI Technical Summary

Problems solved by technology

[0007] (1) The probability of error in the control system is high: both conventional and superconducting maglev trains must have a set of complex and expensive suspension and guidance control units to ensure the stable suspension of the system

Due to the many control components and control links, the probability of error is high, and any error in any link may cause a catastrophic accident on the train running at high speed in the vacuum pipeline;

[0008] (2) The car body is heavy and the payload is low: a large number of on-board electromagnets on the conventional magnetic levitation train, the complex and huge low-temperature circulation system on the superconducting magnetic levitation train, and the Dewar tanks for storing or transporting liquid nitrogen for the system are all As a result, the car body is heavy and the payload is low, which is not suitable for high-speed or ultra-high-speed operation of trains in vacuum pipes;

[0009] (3) Existing superconducting maglev trains have high magnetic fields, which easily cause electromagnetic pollution to the compartments;

[0010] (4) The existing braking system of maglev trains is relatively complex, generally divided into three common types: common braking, emergency braking and fast braking, and there are mainly three braking methods: regenerative braking and eddy current braking And air-hydraulic conversion braking; regenerative braking is preferred for common braking and quick braking. When the regenerative braking force is insufficient, air-hydraulic conversion braking can be used to supplement. Emergency braking generally only uses air-hydraulic conversion The braking method mentioned above is only suitable for the braking of medium and low speed maglev trains, not for maglev trains running at high speed or ultra high speed in vacuum pipes.
