Problems solved by technology

[0005] However, the existing guidance and eddy current braking technology for conventional high-speed maglev trains has the following disadvantages: the guidance system and the eddy current braking system need to be independently configured, and their respective functions are relatively single; For the eddy current braking electromagnet, it will cause excessive concentration of braking force, and it is easy to damage the vehicle structure during high-intensity eddy current braking; under the condition of low-speed train operation, in fact, it mainly depends on the mechanical friction between the eddy current braking electromagnet and the track. , this kind of friction is also very concentrated, and it is also easy to damage the structure of the vehicle

Embodiment Construction

[0023] The specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0024] The electromagnet device integrating guidance and eddy current braking of a high-speed maglev train according to the present invention has six magnetic poles arranged along the forward direction of the train, so that the electromagnet has a U-shaped structure.

[0025] Such as figure 1 As shown, each magnetic pole 10 is a U-shaped structure in which the two pole surfaces are respectively parallel to the upper and lower surfaces of the guide rail surface 200, including an iron core 11, a coil 12 wound outside the iron core 11, and magnetic poles sandwiched at both ends of the iron core 11. The yoke 13 ; the iron core 11 and the yokes 13 at both ends constitute the U-shaped structure of the magnetic pole 10 . By changing the direction of the current applied to the coil 12, the polarity distribution on the magnetic pole 10 can be changed.

Abstract

The invention relates to a high speed maglev train guiding and eddy current braking integrative electromagnet device, comprising a plurality of magnetic poles arranged along the advancing direction of train; wherein the polar plane of the magnetic pole is parallel with a guide rail plane, adjacent magnetic poles are connected in series, thus forming a plurality of groups, and the polarities of each group of magnetic poles arranged on the same polar plane of the electromagnet are consistent, structure is simple, and function is reasonable. The magnetic poles which are uniformly distributed at the two sides of a complete train are changed, so that the polarities of a plurality of magnetic poles arranged on the same polar plane of the electromagnet at each side of the complete train are the same or alternately changed, so as to realize vehicle guiding and eddy current braking functions. The existing special eddy current braking device is not required, thus simplifying structure of system. The electromagnet used for eddy current braking only in the prior art is changed into the guiding and eddy current braking integrative electromagnet of the invention, namely a pair of guiding electromagnets are added for the complete train, guiding capacity of the complete train is improved by 1 / 7, and guiding force and eddy current braking force can be more uniformly distributed at the two sides of the train, braking effect is better, and damage to train structure can be effectively inhibited.

Description

technical field [0001] The invention relates to an electromagnet device, in particular to an electromagnet device integrating guidance and eddy current braking for a high-speed maglev train. Background technique [0002] In the prior art, the conventional high-speed maglev train is equipped with a special guiding system and eddy current braking system, that is, six pairs of guiding electromagnets and a pair of eddy current braking electromagnets are installed on both sides of the single-section maglev train along the track. The eddy current brake magnet module is located in the middle of the train. [0003] A single guide electromagnet consists of 6 "U"-shaped magnetic poles to form an "E"-shaped structure. According to the different installation positions of the guide magnets on the vehicle, the 6 magnetic poles can be divided into two or three groups for control, and each group corresponds to a guide control system. When connecting the magnetic poles, it must be ensured ...
