Slipper brake of maglev train

Abstract

The invention provides a slipper brake of a maglev train, and relates to the technical field of maglev train brake. The slipper brake of the maglev train includes a line sleeper and a suspension frame, wherein cantilever type magnetic steel rails are both arranged on the two sides of the line sleeper. The cross section of the suspension frame is of a semi closed structure, the top portion and twosides of the semi closed structure are closed, an opening is formed in the middle section of the bottom portion of the semi closed structure, and cantilevers are arranged on the two side of the semi closed structure. Electromagnets are arranged on the upper surface, located on the lower portion of the far ends of the magnetic steel rails, of the cantilevers on the two side of the bottom portion. Rubber pads are arranged on the inner surface, located on the upper portion of the near ends of the magnetic steel rails, of the two sides of the suspension frame. Brake sliders are fixed with steel plates on the lower surfaces of the rubber pads through bolts. The steel plates are both arranged on the upper surface and the lower surface of the rubber pads, and the steel plates are fixed with the rubber pads through a plate vulcanization process. The rubber pads are fixed with the inner surface of the top portion of the suspension frame by the steel plates on the upper surface. The material hardness of the brake sliders is less than the material hardness of the magnetic steel rails. The slipper brake of the maglev train is mainly used for the braking of the maglev train.

Description

technical field [0001] The invention relates to the technical field of maglev trains, in particular to a braking technology for maglev trains. Background technique [0002] Compared with wheel-rail trains, the significant advantage of maglev trains is that there is less contact movement between parts, which avoids mechanical wear and subsequent maintenance. For example, linear motors are used instead of rotating motors, and wheel-rail contact is changed to suspension. However, the mechanical braking method of the maglev train still follows the traditional hydraulic caliper braking method. The hydraulic caliper is composed of a hydraulic cylinder and a brake caliper. This set of devices not only has many moving parts but also takes up space. The maglev train has a landing braking method in times of crisis, but it did not follow this line of thinking to study, but followed the hydraulic caliper braking method. [0003] The wheel-rail braking process is the speed of the braked...
