Embodiment Construction
[0015] The present invention is composed of two parts, the slot base and the permanent magnet group, wherein:
[0016] Groove base: It is composed of the bottom of the groove and the wall of the groove. Made of ferromagnetic metal (such as carbon steel Q235). The groove bottom and the groove wall are flat and smooth, and the two groove walls extend parallel to the longitudinal direction.
[0017] Permanent magnet group: Composed of permanent magnets symmetrically from the center to the outside: the main permanent magnet is in the center of the slot base. The N pole of the main permanent magnet is toward the slot, the S pole is toward the bottom of the groove, the two side permanent magnets are on both sides of the main permanent magnet, the N pole is toward the main permanent magnet, and the S pole is toward the groove wall.
[0018] The permanent magnet group is embedded in the groove base to form energy-concentrating permanent magnet tracks and energy-concentrating permane...

The invention relates to a cumulative energy permanent magnetic suspension device. The lower lateral surfaces of both ends of a suspension engine compartment are respectively provided with a cumulative energy permanent magnetic wing in the position of both ends of the suspension engine compartment corresponding to an arched hanging pillow; the upper lateral surfaces of both ends of the arched hanging pillow are respectively provided with a cumulative energy permanent magnetic rail; the cumulative energy permanent magnetic wings and the cumulative energy permanent magnetic rails have the same structure which comprises a groove base and a permanent magnetic group, wherein the groove base is integrally made of ferromagnetic materials and provided with a groove bottom and groove walls; the twogroove walls extend in parallel in the longitudinal direction; the permanent magnetic group is permanent magnets made of hard magnetic materials and embedded in the groove base; the permanent magnetsinclude a main permanent magnet and two side permanent magnets; the main permanent magnet is arranged in the center of the groove base, and the N pole of the main permanent magnet faces a groove opening; the two side permanent magnets are respectively arranged between the main permanent magnet and the groove walls of the groove base, the N pole of each side permanent magnet faces the main permanent magnet, and the S pole of each side permanent magnet faces the groove walls; and the cumulative energy permanent magnetic wings of the lower lateral surfaces of both ends of the suspension engine compartment and the cumulative energy permanent magnetic rails installed on the upper lateral surfaces of both ends of the arched hanging pillow are arranged up and down in the mode of homopolar alignment.
Description
technical field [0001] The invention belongs to the technical field of permanent magnetic levitation, and in particular relates to an energy-gathering permanent magnetic levitation device composed of a permanent magnetic levitation rail and a permanent magnetic levitation wing. Background technique [0002] One of the levitation force sources of levitation devices such as permanent maglev trains is the repulsive force generated by the corresponding magnetic poles between the rail permanent magnets installed on the track and the car permanent magnets installed on the train. A non-ferromagnetic interlayer is arranged between the permanent magnet and the ferromagnetic groove wall of the energy-gathering permanent magnetic levitation wing on the existing energy-gathering permanent magnet track and train. Although this method effectively increases the levitation force, it also wastes the space of the ferromagnetic groove, and is not conducive to the further increase of the levita...
