Embodiment 1

[0038] A magnetic levitation device with levitation and guidance, such as Figure 1-5As shown, it includes a track 1, the upper surface of the track 1 includes inwardly inclined slopes 11 located at both ends, and the suspension reaction rails 3 are respectively arranged on the two slopes 11; specifically, the clamping of the slope 11 relative to the horizontal plane The angle size is α, where 20°≤α≤50°.

[0039] At least one suspension frame 2 is located above the track 1, and a row of permanent magnet array groups inclined outward is provided at both ends of the bottom of each suspension frame 2, and each row of permanent magnet array groups includes at least one permanent magnet Array 4, specifically, the permanent magnet array is a ring-shaped Halbach permanent magnet array, each of the permanent magnet arrays 4 is arranged opposite to the suspension reaction rail 3, and the permanent magnet array groups at the two ends of the suspension frame 2 have The angle of outward ...

Embodiment 2

[0049] A maglev train, comprising a car body 8, and also includes the maglev device with suspension and guidance in Embodiment 1, the car body 8 and each suspension frame 2 of the maglev device with suspension and guidance through a suspension assembly 7 connected.

[0050] The maglev train in this embodiment 2 is connected with the maglev device with suspension and guidance through the car body 8, because the maglev device with suspension and guidance is provided with the suspension reaction rail 3, through the interaction with the permanent magnet array group , that is, when the driving motor 6 drives the rotating permanent magnet array group, it can generate induced currents with the levitation reaction rail 3 respectively. , and the guiding force horizontally to the inner side of the track realizes the suspension and guidance of the maglev train. The maglev train can realize static levitation, self-stabilized suspension, and self-stabilized guidance. The maglev train has ...

Embodiment 3

[0052] A kind of maglev system, comprises the car body 8 of several maglev trains as described in embodiment 2 that are connected with each other, and has the magnetic levitation device that has suspension and guidance as described in embodiment 1, all described car body 8 bottoms and all Each suspension frame 2 with the above-mentioned magnetic levitation device for suspension and guidance is connected by a suspension assembly 7 .

[0053] The maglev system described in Embodiment 3 includes several car bodies 8, and each car body 8 is connected to the maglev device with suspension and guidance in Embodiment 1, which is suitable for existing maglev rail trains and has good versatility.

Abstract

The invention relates to the technical field of magnetic levitation devices with levitation and guidance and particularly relates to a magnetic levitation device with levitation and guidance, a magnetic levitation train and a magnetic levitation system. Suspension reaction rails on two sides of the rail are arranged to be at a certain inclination angle, so repulsive force between the permanent magnets and the suspension reaction rails is inclined upwards, two components in the horizontal direction and the vertical direction are generated respectively, and suspension of the suspension train in the vertical direction is achieved through the vertical components; when the device loaded on the annular permanent magnet electric suspension system inclines towards one side, the repulsive force borne by the permanent magnet on the corresponding side is increased accordingly, the horizontal component is also increased accordingly, then reaction is generated on the device loaded on the annular permanent magnet electric suspension system, the device is pushed towards the opposite direction, and guiding of the load device is realized. According to the device, the track and the train are simple in structure, and the system is high in reliability, easy to implement and particularly suitable for medium-low-speed maglev train systems.

Description

technical field [0001] The invention relates to the technical field of a levitation and guidance maglev device, in particular to a levitation and guidance maglev device, a maglev train and a maglev system. Background technique [0002] The maglev train is a train system that uses a non-contact electromagnetic levitation, guidance and drive system. It relies on electromagnetic attraction or electric repulsion to suspend and guide the train in the air, realizes the non-mechanical contact between the train and the ground track, and uses a linear motor to drive the train to run. According to the running speed of vehicles, maglev trains can be divided into two types: high-speed and medium-low speed: high-speed maglev trains can run at a maximum speed of more than 500km / h, and adopt EMS and EDS two suspension methods, which are suitable for long-term trunk lines and big cities Passenger transportation between cities; medium and low-speed maglev trains run at a speed of about 100k...
