Anti-suspension contact device for maglev train

Abstract

The invention discloses an anti-suspension contact device for a maglev train, which comprises more than one support part fixed on an electromagnet for being in rolling fit with a rail. The anti-suspension contact device has the advantages of simple and compact structure, low cost and convenience in mounting, and can reduce the abrasion of the rail and the impact to a secondary system on the maglev train.

Description

Anti-sucking device for maglev train technical field The invention mainly relates to the field of magnetic levitation trains, in particular to a device for preventing a dead state between a magnetic levitation train and a track. Background technique The magnetic levitation train relies on the attraction of electromagnets to make the train levitate on the track to realize operation. In order to maintain a certain gap between the electromagnet and the track and prevent the phenomenon of sucking dead, certain measures must be taken. Adopted on the traditional magnetic levitation train is the mode that pad 3 is installed on the electromagnet top. Referring to Fig. 1, the iron core 2 and the coil 1 wound on the iron core 2 constitute the electromagnet of the maglev train. And located between the electromagnet and track 4. When there is a danger of sucking dead between the electromagnet and the track 4, a safety gap is still maintained between the electromagnet and the track ...

AI Technical Summary

Problems solved by technology

(1) There is a large friction between the pad 3 and the track 4, and the track 4 will also be worn during the anti-suction process, which will shorten the service life of the track 4 and greatly increase the operating cost;

(2) Due to the inertia of the train car, the tendency of the car to continue moving along the track 4 will have a greater impact on the secondary system, and even destroy the secondary system.
