Embodiment Construction

[0007] Among them, it is composed of a large magnetic block and a small magnetic block; the two large magnetic blocks are arranged in parallel with the same magnetizing direction, and the small magnetic block with the opposite magnetic field direction is sandwiched in the middle; the length of the two large magnetic blocks is the length of the small magnetic block. 4 times; three magnet blocks are flanked by a plane, forming a magnet block group.

[0008] The key technical point of this structure is that the length of the two large magnet blocks is more than 4 times the length of the middle small magnet block.

Abstract

The invention provides a planar magnetic levitation structure with a large magnet block group and a small middle magnet block opposite in magnetizing direction. The planar magnetic levitation structure comprises a large magnet block 1, a large magnet block 2, a small magnet block 3 and other parts, wherein the large magnet block 1 and the large magnet block 2 are parallel and the same in magnetizing direction, between which the small magnet block 3 opposite to the large magnet block 1 and the large magnet block 2 in magnetizing direction is clamped; the length of the large magnet blocks are 4 times of that of the small magnet block; the side surfaces of the three magnet blocks are in the same plane surface, so as to form a magnet block group.

Description

[0001] The present invention involves a flat magnetic suspension structure with a large magnetic block group and the middle small magnetic block, especially a magnetic suspension infrastructure that moves parallel to each other.It belongs to the field of magnetic suspension technology. Background technique [0002] At present, the infrastructure of various magnetic suspension trains is mainly based on electromagnetic suspension. Only Dalian tests a permanent magnet suspension train, but its infrastructure is the end -surface reprimination type.According to our large number of experiments, the end -faceted pole reproduction technology can lead to permanent magnetic degeneration.In this way, the stability of the magnetic suspension train will be greatly reduced. Invention content [0003] The problem to be solved by the present invention is that the relative parallel motion magnetic suspension structure can prevent the suspension magnetic block degradation when the large load is ach...
