Anti-rolling device for maglev train

Abstract

The invention discloses a side-rolling resisting device for magnetically levitated trains. The side-rolling resisting device is arranged between levitation modules (1) and comprises three groups of parallelogram structures including a main parallelogram structure in the middle and auxiliary parallelogram structures on two sides, and the auxiliary parallelogram structures are connected with the levitation modules (1) on corresponding sides. The side-rolling resisting device can evidently improve postural stability of a moving mechanism during static and suspended running of a magnetically levitated train to enable the modules on the left and right to decouple when the train starts levitation, so that static levitation capacity and curve passage capacity of the train are improved and the maximum speed for stable running of the train is increased.

Description

technical field [0001] The invention relates to the technical field of magnetic levitation trains, in particular to an anti-rolling device for medium and low-speed magnetic levitation rail transit vehicles. Background technique [0002] Existing medium and low-speed maglev trains (with a speed level of about 120km / h) are supported by electromagnetic attraction to make them non-contact with the track, and are driven by linear motors to realize train operation. [0003] The suspension of medium and low-speed maglev trains is realized by the suspension modules arranged on both sides of the running mechanism. At the same time, traction devices are arranged on the modules to push the train forward. The lateral connection of the left and right modules is realized by anti-roll beams. [0004] The existing anti-roll beam is a parallelogram structure composed of plate girders, and the connection of two sets of plate girders is a flexible structural member. Although this solution can...

Problems solved by technology

As a result, the suspension running ability and curve passing ability of the train are reduced, and the stable running speed of the train is also limited.

[0005] The invention patent application with the publication number CN102501871A discloses an anti-roll beam for the bogie of a maglev train, which uses a flexible connector, and the connection between the two ends of the flexible connector and the plate girder is a consolidated connection This method limits the lateral stretching of the two sets of plate girders, and can only achieve a certain degree of diamond deformation through flexible deformation.

At the same time, under the action of the torque of the train on this flexible structure, the connecting piece will stretch or compress along the length of the rod, so that the original parallelogram structure cannot be maintained. The relationship between the left and right suspension modules and the track in the curve passing state is a translation plus The rotation effect is not ideal
