A static levitation device for permanent magnet electric maglev train

Abstract

The invention discloses a static levitation device for a permanent magnet electric maglev train, which enables the permanent magnet electric levitation train to realize controllable static levitation. It includes bogies installed on maglev trains, cylindrical permanent magnet module groups arranged on the bogies, and special-shaped guide rails matched with cylindrical permanent magnet module groups. In a bogie, four cylindrical permanent magnets are used to form a group of cylindrical permanent magnet modules: four cylindrical permanent magnet modules are symmetrically arranged on the left and right side edges of the bogie, and two cylindrical permanent magnet modules on each side edge The shaped permanent magnet module is coaxially installed on the two output shafts of the rotating biaxial extension motor, and the output shaft of the biaxial extension motor coincides with the geometric center of the semi-cylindrical guide groove. By adopting the structure of the invention, the permanent magnet electric levitation train can realize static levitation, and the guide rail with the semi-cylindrical guide groove can provide the levitation force and the vehicle guide force at the same time.

Description

technical field [0001] The invention relates to the technical field of magnetic levitation trains, in particular to a levitation device for permanent magnet electric levitation trains. Background technique [0002] The permanent magnet electric maglev train mainly uses the principle of Lenz's law, the magnetic field generated by the permanent magnet on the train, when the train is running, the magnetic force line is cut by the closed coil on the track, thereby generating an induced current in the closed coil, The direction of this induced current is to prevent the change of the magnetic flux of the original magnet, thus generating the levitation force. The advantage is that, at the application speed, the levitation gap is large and active control is not required. [0003] At present, there are two main types of levitation devices for electric maglev trains: 1. superconducting electric levitation, such as Japan's MLX superconducting maglev train; 2. permanent magnet electric...

Problems solved by technology

[0006] However, the above two electric suspension methods cannot be suspended when they are stationary. When running at low speeds, the suspension force is not enough to make the train suspend on the guide rails. It needs to be supported by wheels, and it must reach a certain speed before it can float.
