Problems solved by technology

[0004] At present, the tracks of maglev trains mainly include F-shaped rails and rectangular rails. The rectangular rails are characterized by smaller thickness but larger width, which are suitable for medium and high-speed maglev trains (travel speed greater than or equal to 200km / h), while the existing technology The magnetic rail brakes used by medium rail trains are generally in the form of bipolar shoes. If the magnetic rail brakes used for rail trains in the prior art are applied to maglev trains with rectangular rails, the thickness of the rectangular rails is smaller than the rails of the rail trains, resulting in Fewer lines of flux circulate in the rectangular track, which in turn reduces the braking force of the magnetic track brake

Abstract

The invention provides a magnetic track brake and a magnetic suspension train. The magnetic track brake is arranged on the magnetic suspension train with a rectangular track. The magnetic track brakecomprises an iron core unit, the side, facing the rectangular track, of the iron core unit is wound with magnet exciting coils, and the opposite sides of the iron core unit are connected with a side plate unit. The end, facing the rectangular track, of the side plate unit is connected with an outer pole shoe unit. The multiple magnet exciting coils are arranged in the direction relative to the side plate unit, the side, facing the rectangular track, of the iron core unit is connected with a plurality of inner pole shoes, and the inner pole shoes are arranged corresponding to the magnet exciting coils in the direction relative to the side plate unit. The magnetic suspension train is provided with the magnetic track brake. The magnetic track brake can provides enough braking force for the magnetic suspension train in high-speed operation, and the magnetic suspension train has high operation safety accordingly.

Description

technical field [0001] The invention belongs to the technical field of magnetic levitation trains, in particular to a magnetic track brake and a magnetic levitation train. Background technique [0002] The maglev train is a modern high-tech rail vehicle. It uses electromagnetic force to achieve non-contact suspension and guidance between the train and the track, and then uses the electromagnetic force generated by the linear motor to drive the train. The mechanical braking forms of maglev trains mainly include hydraulic braking and eddy current braking. Among them, hydraulic braking performs braking through friction with the rail surface. , the friction coefficient between it and the rail surface is significantly reduced, so the braking force is also reduced, and the heat capacity of the brake pad is also difficult to meet the requirements. In addition, there are environmental pollution problems such as oil leakage; eddy current braking is a non-contact brake. It uses the p...
