Permanent magnetic levitation track, magnetic levitation mechanism and magnetic levitation train
The invention provides a permanent magnetic levitation track, a magnetic levitation mechanism and a magnetic levitation train. The permanent magnetic levitation track comprises a plurality of track sections, the plurality of track sections are sequentially arranged along the length direction of the permanent magnetic levitation track; and a butt joint seam is arranged between the opposite end faces of every two adjacent track sections. Each butt joint seam comprises at least one first joint section, and the included angle between the extending direction of the first joint section and the length direction is an acute angle. On the basis of optimization of the butt joint seam structure, the suspension force loss when the magnetic levitation train passes through the butt joint seams is reduced, the displacement interval of suspension force descending and ascending when the magnetic levitation train passes through the butt joint seams can be lengthened, discomfort caused by sudden descending and sudden ascending of the suspension force to passengers is effectively relieved, and the running safety and stability of the magnetic levitation train are ensured.
本发明提供一种永磁磁悬浮轨道、磁悬浮机构及磁悬浮列车，所述永磁磁悬浮轨道包括：多个轨道节段；所述多个轨道节段沿所述永磁磁悬浮轨道的长度方向依次设置；所述多个轨道节段当中相邻的两者的相对端面之间设有对接缝；所述对接缝包括至少一个第一接缝段，所述第一接缝段的延伸方向与所述长度方向的夹角呈锐角。本发明基于对对接缝结构的优化，降低了磁悬浮列车过对接缝时的悬浮力损耗，可以拉长磁悬浮列车过对接缝时悬浮力下降与上升的位移区间，有效缓解了悬浮力的急降与急升给乘客带来的不适，确保了磁悬浮列车运行的安全性与稳定性。
