Embodiment 1

[0026] Example 1: Please refer to Figure 7 , the soft magnetic track 2 and the guide track 4 are installed on the bottom of the viaduct 6, and the vehicle-mounted magnet 1 and the guide drive wheel 3 are installed on the top of the train compartment 6 to form a roof suspension type maglev train. The magnetic levitation system of this embodiment adopts a single-layer structure, and the number of slots of the soft magnetic track and the number of magnets arranged on the vehicle are determined according to the required magnetic levitation force of the weight of the train. The single-layer magnetic levitation structure can meet the magnetic levitation force required by passenger trains. If greater magnetic levitation force is required, a multi-layer magnetic levitation structure can be used.

Embodiment 2

[0027] Example 2: Please refer to Figure 8 , the soft magnetic track 2 and the guide track 4 are installed on the top of the subgrade 6, and the vehicle-mounted magnet 1 and the guide drive wheel 3 are installed on the bottom of the train 6 to form a suspension type maglev train at the bottom of the vehicle. The magnetic levitation system of this embodiment adopts a multi-layer structure, which can meet the needs of the large load capacity of freight trains. The number of layers of the magnetic levitation system can be determined according to the magnetic levitation force required by the maximum weight of the train.

Embodiment 3

[0028] Embodiment 3: Utilize the comb-groove type magnetic levitation system of the present invention, but the guiding and driving systems respectively adopt electromagnets to control the guiding and linear motors to drive the train to form a completely non-contact magnetic levitation train. The electromagnet of this embodiment is installed on the compartment relative to the both sides of the guide rail, and a certain gap is maintained between the magnetic poles of the electromagnet and the guide rail, and sensors and electronic controllers are used to detect and control the gap distance between the electromagnet and the guide rail, thereby Control the vehicle-mounted magnet in the center of the soft magnetic track groove.

Abstract

The invention discloses a comb-groove-shaped magnetic suspension mechanism, which has the characteristic that a magnetic suspension force changes automatically along with the weight of a train and is suitable for a permanent-magnet magnetic suspension train. A track is manufactured by using a soft magnetic material. A magnetic suspension train system comprises a soft magnetic track, a vehicle-mounted magnetic body system, a guide track and a guiding and driving integrated wheel hub system, wherein the soft magnetic track is arranged on a subgrade; the cross section of the track has a comb-shaped structure; a plurality of grooves are formed between adjacent comb teeth; vehicle-mounted strip-shaped magnetic bodies are arranged on a nonmagnetic substrate at equal distance; an entire cross section has a comb-shaped structure like the track; the magnetic bodies are sucked in a staggered way relative to tooth spaces of the soft magnetic track; each magnetic body produces oblique attractive force together with the tooth spaces on both sides, and the oblique attractive force is combined into upward the magnetic suspension force; a rubber wheel of a driving motor is arranged in the center of a guide driving wheel hub; a pressure sensor and a pressure regulator are arranged on a bracket, and is in mechanical contact with a guide rail; and the comb-groove-shaped magnetic suspension mechanism has the functions of preventing the magnetic body from contacting the center of a soft magnetic track groove and driving a train to move.

Description

technical field [0001] The invention belongs to the technical field of magnetic levitation trains, and relates to the composition of a magnetic levitation system, and a guiding and driving system. The invention provides a comb-shaped magnetic levitation train system with a simple structure and a guiding and driving integrated system. Background technique [0002] Maglev train is a new type of transportation developed in recent decades, featuring high speed, stability and comfort. At present, there are mainly three types of maglev train technologies being developed and applied. The technically mature ones include the German maglev train, which has reached the level of commercial use, such as the Pudong Airport Special Line maglev train built in Shanghai. The other two are The superconducting maglev train developed in Japan and the newly developed permanent magnet maglev train in China. Although the conventional magnetic levitation train technology has reached the level of c...
