Problems solved by technology

Such a suspension system does not have a redundant design. When the suspension electromagnet pole 2, the suspension electromagnet pole 3, or the suspension controller 6 and their related sensors fail, the suspension point cannot be suspended normally, and this side of the suspension frame 1 will lose Half of the suspension force, the support sled corresponding to the suspension point will have continuous contact with the track, causing the train to decelerate and stop running after clearing passengers at the nearest station, which will generally cause the train to be delayed or cancel the number of running trains, affecting the system availability index

Embodiment 1

[0022] Such as figure 1 As shown, a medium and low speed maglev train levitation redundancy system includes multiple sets of levitation units, each set of levitation units includes a levitation controller and two levitation electromagnet poles connected in series, the levitation electromagnet poles Connect to the suspension controller. Any group of suspension units is equipped with at least one group of mutually redundant suspension units, and the suspension force centerlines of mutually redundant suspension units overlap each other. In this embodiment, any group of suspension units is configured with a group of mutually redundant suspension units. The remaining suspension unit.

[0023] The system includes four groups of suspension units, of which two groups are located in the front half of the suspension frame, two groups are located in the rear half of the suspension frame, and the two groups of suspension units in the front half of the suspension frame and the rear half of th...

Embodiment 2

[0028] In this embodiment, any group of suspension units are equipped with at least two groups of mutually redundant suspension units, and the rest are the same as in Embodiment 1. Specifically, on the basis of Example 1, a set of suspension units are added to the front half of the suspension frame 1 and the rear half of the suspension frame 1, respectively. The suspension force center line of the suspension unit added in the front half of the suspension frame 1 is located at the position of the suspension frame. At one quarter, the centerline of the suspension force of the suspension unit added in the rear half of the suspension frame 1 is located at three quarters of the suspension frame.

Abstract

The invention relates to a medium-low-speed magnetic-levitation train redundant system which comprises a plurality of groups of magnetic-levitation units. The redundant system is characterized in thatany group of magnetic-levitation units are provided with at least one group of mutually redundant magnetic-levitation units, and the center lines of the mutually redundant magnetic-levitation units are mutually overlapped. Compared with the prior art, the set redundant magnetic-levitation units can effectively avoid continuous contact of a magnetic-levitation frame and a rail, running usability of the magnetic-levitation system is improved, and safe and stable running of a train is ensured.

Description

Technical field [0001] The invention relates to the technical field of rail transit vehicles, in particular to a medium and low speed maglev train suspension redundancy system. Background technique [0002] Maglev train is a major technological innovation in the field of transportation. The maglev train realizes the non-contact levitation and guidance between the train and the track through electromagnetic force, and then uses the electromagnetic force generated by the linear motor to drive the train. As a mode of maglev train, medium and low speed maglev trains have the advantages of low noise, high comfort, and good environmental performance. They can meet the transportation needs within the city, between suburbs and short-distance intercity. [0003] Stable and reliable realization of train suspension is the basis for ensuring the punctual operation of maglev trains. At present, medium and low-speed maglev trains adopt electromagnetic levitation technology, relying on multiple...
