Embodiment Construction

[0048] The present invention is described in further detail now in conjunction with accompanying drawing.

[0049] Such as figure 1 Shown, be a kind of permanent magnet drive maglev rail 1 of the present invention, rail section is substantially C-shaped, and one side of section is current I-shaped rail shape (or half), and the other side extends obliquely at the top of I-shaped. boards and tablets. The C-shaped permanent magnet drive maglev steel rail 1 can be a continuously cast rail extruded.

[0050] The specific structure of the permanent magnet drive maglev rail 1 is that the bottom is a support base plate 7, and the support base plate 7 is a waist plate 5. In order to realize compatibility with the wheel-rail train, a side guide surface 2 and an upper support surface 3 are set on the upper part of the waist plate 5. The upper supporting surface 3 of the upper part of the waist plate 5 is connected with an upper sloping plate 4 , and the upper sloping plate 4 is connect...

Abstract

The invention provides a permanent-magnet-driven maglev track. The permanent-magnet-driven maglev track is characterized in that one side of the section of a permanent-magnet-driven maglev steel rail is I-shaped; an inclined plate and / or circular arc plate extends on the upper part or the lower part of an I shape on the other side; and a flat plate is further connected. The permanent-magnet-driven maglev track consisting of the permanent-magnet-driven maglev steel rails and spiral stators is fixed on a roadbed or a sleeper through embedded bolts and fasteners, and is constructed into a safe, high-speed, energy-saving and high-cost performance rail transit system. The permanent-magnet-driven maglev track is convenient to lay, good in elasticity and strong in compatibility; the construction cost of the permanent-magnet-driven maglev track is equivalent to that of a wheel and rail railway; and the permanent-magnet-driven maglev track provides a constructive reference scheme for rail transit infrastructure construction of a country.

Description

Technical field [0001] The invention relates to the technical field of rail transportation, in particular to a magnetic levitation track system, in particular to a track system for permanent magnetic levitation wheel-rail trains driven by linear permanent magnets. Background technique [0002] Magnetic levitation trains have the characteristics of safety, high speed and low noise, so all countries are developing new types of magnetic levitation trains. Germany's EMS electromagnetic levitation track requires elevated construction, which requires a large amount of reinforced hydraulic concrete materials. Silicon steel sheets and conductive coils are laid on the inverted T-shaped elevated track, and the track construction cost is high. Japan's EDS superconducting electromagnetic suspension high-speed train has suspension and drive coils on both sides of the U-shaped cross-section track, which requires superconducting materials and low-temperature refrigeration technology, and t...
