Abstract

The invention provides a permanent magnet rail. The permanent magnet rail is structurally characterized in that the permanent magnet rail is formed in the modes that iron cores 3 with magnetoconductivity are arranged in middle grooves of permanent magnets 2 with the U-shaped or semicircular sections, magnetic poles of the permanent magnets 3 which are overall in a U or semicircle shape are magnetized in the radial direction, and the sections extend along straight lines or curves. The bottom of the permanent magnet rail 1 is provided with a permanent magnet rail chair 9, the section of the permanent magnet rail chair 9 is provided with a U-shaped groove, and the section with the U-shaped groove is matched with the external section of the permanent magnet rail 1; and the U-shaped or semicircular permanent magnets 3 which are the same in structure but opposite in polarity are arrayed together to form the double-pole or multi-magnetic-pole permanent magnet rail. The permanent magnet rail can be constructed into a safe, economic and energy-saving superconducting magnetic levitation permanent magnet rail and vacuum pipeline ultrahigh-speed magnetic levitation rail traffic system.

Description

technical field [0001] The invention relates to the technical field of road traffic and rail traffic, in particular to a high-temperature or low-temperature superconducting maglev permanent magnet track and a superconducting maglev vehicle, especially for energy-saving road traffic and rail traffic, as well as vacuum pipeline ultra-high-speed trains and rail systems. Background technique [0002] The high-temperature superconducting suspension has the characteristics of self-stabilizing suspension, which simplifies the suspension control system and is very energy-saving in operation. However, the permanent magnet track is composed of multiple high-performance square permanent magnets. Due to the repulsion of the permanent magnetic field, the internal stress is large. difficulty. [0003] The surface magnetic field of multiple square permanent magnets on the permanent magnet track is not uniform. Due to the uneven permanent magnetic field during the suspension movement of the...
