Problems solved by technology
In particular, when the high-temperature superconducting material is in a mixed state, the pinning force and the restoring force can be provided to restore the equilibrium position according to the needs of the stressed state of the superconducting bulk material. The floating range of the suspension height is small, and the disadvantage is that the suspension force and recovery The force is limited, the load capacity is limited, and it is difficult to meet the needs of large-capacity rail transit

Embodiment Construction
[0020] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0021] Such as figure 1 and figure 2 As shown, the preferred embodiment of the present invention provides a magnetic levitation mechanism, which can be applied to various mobile vehicles, such as urban subways, freight trains and passenger trains. The magnetic levitation mechanism includes a permanent magnet track 2 , a vehicle-mounted permanent magnet 3 , a chassis 1 of a mobile vehicle, and a high-temperature superconducting block 4 . The permanent magnetic track 2 is laid on the roadbed, and the chassis 1 is located directly above the permanent magnetic track 2 . Among them, the vehicle-mounted permanent magnet 3 is fixed on the chassis 1 and has the same polarity as the permanent magnet rail 2 and is vertically opposite to...

The invention discloses a magnetic levitation mechanism and a magnetic levitation train. The magnetic levitation mechanism comprises a permanent magnetic railway, a vehicle-mounted permanent magnet, a chassis of a moving vehicle and a high-temperature superconducting block, wherein the vehicle-mounted permanent magnet is fixedly arranged on the chassis, and is homopolar with and vertically opposite to the permanent magnet railway, and the high-temperature superconducting block, opposite to the chassis, can be vertically and movably arranged on the chassis and is opposite to the permanent magnetic railway. The moving vehicle that adopts the magnetic levitation mechanism disclosed by the invention has relatively great guiding force and lateral stability relative to a permanent magnetic levitation train in the prior art, and has relatively great suspension force so as to have relatively great carrying capacity in comparison with a high-temperature superconducting magnetic levitation train in the prior art, thereby making up for the defects of two kinds of magnetic levitation trains.
Description
technical field [0001] The invention relates to the technical field of magnetic levitation, in particular to a magnetic levitation mechanism and a magnetic levitation train for improving the magnetic levitation performance and guiding performance of vehicles. Background technique [0002] Maglev trains have become an important direction in the development of passenger and freight transportation. Generally, maglev trains can be divided into permanent maglev trains, constant conduction maglev trains and high-temperature superconducting maglev trains. [0003] Both permanent magnetic levitation and high temperature superconducting magnetic levitation technology belong to passive magnetic levitation, and the common feature is that the structure is simple and almost no active control is required. For permanent magnetic levitation, when using NdFeB permanent magnet material with strong coercive force, thanks to the superior performance of this permanent magnetic material, it can o...
