Abstract

The invention provides a segmented railroad switch, comprising an active beam and at least one inactive beam, while each beam is mounted with F track, and each beam is connected with each other via connectors, the nearby beams are arranged with a joint plate as transition and connected with nearby beams via connectors. The invention is characterized in that the joint plate is arc shaped comprising two joint plate F tracks, and the connectors connecting the F tracks, the end of the F track is arc shaped, while the end of the F track of each nearby beam is arc shaped. In straight state, the arc end of the F track of the joint plate and the arc end of the F track of the beam form two concentric arcs. The invention can effectively reduce the impact generated by hydraulic brake and bias moved beam, to stably move wheels.

Description

technical field

[0001] The present invention generally relates to a rail transit system, and in particular to a segmental switch for a maglev transit system and / or a monorail transit system. Background technique

[0002] In the low-speed maglev system of the normal-conducting linear induction motor, the two sides of the track beam are π-shaped steel ferromagnetic tracks that cantilever downward. The track and the track beam are connected by sleepers or pillars. The cross-section of the track is F-shaped, so it is also called F. rail. The F rail corresponds to the suspension guide magnet on the train, and its magnetic poles and electromagnets attract each other to make the train suspension rise to a certain height. The upper surface of the F rail is covered with an aluminum plate, which forms an induction armature corresponding to the stator core of the drive motor at the lower part of the train, conducts the induced current, generates an electromotive force in the forward d...
