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.

A suspended rail transit equipment and a magnetic-electric hybrid suspension rail system therein comprise a control unit, rails and vehicle-mounted magnetic-electric rails. The vehicle-mounted magnetoelectric rail includes at least two rows of vehicle-mounted permanent magnet arrays, electromagnets and distance sensors arranged along the running direction of the car; the rail includes a rail permanent magnet array, and the rail permanent magnet array and The vehicle-mounted permanent magnet arrays are staggered at intervals, and the rails and the vehicle-mounted magnetoelectric rails are self-stabilized through mutually exclusive magnetic poles. At the same time, the distance sensor, control unit and electromagnet form a closed-loop control system, wherein the control unit controls the magnitude of the excitation current in the electromagnet through the data of the distance sensor, so that the excitation current excites the magnetic field to keep the permanent magnet array of the rail No contact with the on-board permanent magnet array to achieve hovering. The invention has high hovering rigidity, and a self-stabilizing system is formed by rails and vehicle-mounted magneto-electric rails, and the vibration is small when 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...
