Embodiment Construction

[0030]figure 1 It is a schematic diagram of the maglev train and the track. The maglev train consists of a carriage 1, a levitation mechanism 2 and necessary connectors. Track 3 is a T-shaped structure. The suspension mechanism 2 surrounds the track 3 from both sides. In the non-suspension state, the suspension mechanism 2 is in contact with the track 3, and the maglev train is supported on the track 3 by mechanical force; in the suspension state, the suspension mechanism 2 can be separated from the track 3, and the maglev train travels along the track without friction.

[0031] figure 2 It is a longitudinal sectional view of one side of the suspension system of the present invention, and the other side is symmetrical to it. The carriage 1 is connected to the suspension mechanism 2 through a damping device 10 . The levitation mechanism 2 is equipped with a permanent magnet array 12, a support wheel 13, a U-shaped iron core 14, an electromagnetic coil 15, and a levitation ...

Abstract

The invention discloses an electric electromagnetic mixing levitation system, which is characterized by the following: the invention is mixed with permanent-magnet EDS and electro-magnetism EMS which connect by adapting piece; the permanent-magnet EDS and electro-magnetism EMS are installed on suspension device under the magnetic levitation train and on the path; the permanent-magnet EDS provides main suspension power for the whole suspension system; the electro-magnetism EMS provides small parts of suspension power for system and damping power in vertical direction for permanent-magnet EDS to enhance the anti-interference ability of system and make the all system suspense steady. The invention reduces the fabrication cost of train and path.

Description

technical field [0001] The invention relates to a levitation system of a maglev train, in particular to a levitation system mixed with electric levitation and electromagnetic levitation. Background technique [0002] The maglev train is a new type of vehicle that relies on the attraction or repulsion of magnets to separate the train from the track, and uses a linear motor to drive the train to run along the track. There is no mechanical contact between the maglev train and the ground track, which has the advantages of energy saving, environmental protection, fastness, comfort, etc., and has broad development prospects. According to the levitation principle, the levitation system of maglev trains includes electric levitation type (EDS type), electromagnetic levitation type (EMS type) and permanent magnetic attraction or repulsion type. [0003] The EDS type maglev system uses the repulsive force generated by the relative motion between the magnetic field and the conductor to...
