Suspended rail transit apparatus and magnetoelectric hybrid levitation rail system therein

Abstract

A suspended rail transit apparatus and a magnetoelectric hybrid suspension rail system therein, comprising a control unit, a track and a vehicle-mounted magnetoelectric rail. The vehicle-mounted magnet rail comprises at least two arrays of vehicle-mounted permanent magnets arranged along the running direction of the car, electromagnets and a distance sensor; The rail comprises a rail permanent magnet array, wherein the rail permanent magnet array and the vehicle-mounted permanent magnet array are staggered at intervals, and the rail and the vehicle-mounted magnetoelectric rail are self-stabilized through mutually exclusive magnetic poles. The rail comprises a rail permanent magnet array, a rail permanent magnet array and a vehicle-mounted permanent magnet array. At the same time, the distance sensor, the control unit and the electromagnet form a closed loop control system, wherein the control unit controls the magnitude of the excitation current in the electromagnet through the data ofthe distance sensor so that the excitation current excitation magnetic field keeps the permanent magnet array of the road rail from contacting with the permanent magnet array of the vehicle to realize hovering. The hovering rigidity of the invention is large, the road rail and the vehicle-mounted magnetoelectric rail constitute a self-stable system, and the vibration is small when the road rail and the magnetoelectric rail are loaded.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to rail transportation equipment driven by magnetic suspension. Background technique [0002] Rail transit, because of its relatively independent lines, convenient scheduling, and considerable carrying capacity, has gradually attracted widespread attention. Rail transit equipment driven by magnetic levitation technology is generally considered to be the development direction of transportation tools in the 21st century because of its fast speed, strong climbing ability, small turning radius and its advantages in economic and environmental protection. [0003] At present, the maglev rail transit equipment with relatively mature technology is divided according to the principle of electromagnetic force, and mainly includes the following two driving modes: electromagnetic levitation drive and electric levitation drive. Electromagnetic suspension (EMS for short) is to use the attractio...

AI Technical Summary

Problems solved by technology

[0006] However, since the EMS suspension method cannot achieve self-stabilization, and the EDS suspension method cannot statically float, the current suspended rail trains also need wheel-rail support to realize hovering

However, the wheel-rail support has a lot of mechanical wear during operation, and it is difficult to maintain. During operation, noise is often generated due to wheel-rail friction, which affects the riding experience.
