Problems solved by technology

Moreover, since the levitation force generated by the permanent magnet varies greatly with the air gap, changing a small air gap requires a large force from the electromagnet, so the electromagnetic control is very difficult

Embodiment Construction

[0027] use Figure 1 In a bogie, two permanent magnetic levitation modules and four electromagnetic levitation modules are grouped and arranged in parallel along the direction of the F-shaped track and facing the F-shaped track; the suspension frame is 3 meters long and has a self-weight of 65,000 N. The rated load is 25,000 N, the length of the permanent magnetic levitation module is 1.56 meters, and the length of the electromagnetic levitation module is 0.5 meters.

[0028] The width of the permanent magnetic levitation module is not equal to the width of the F-shaped track, and the main levitation force is provided by the permanent magnetic levitation module. See the attached size parameters for the specific implementation selection Figure 4 , where: M=71mm; D=100mm; G takes 0, 10, 20mm. Wherein the width of the electromagnetic levitation module is equal to the width of the F-shaped track. Auxiliary and adjustable levitation forces are provided by the electromagnetic le...

Abstract

The invention discloses a parallel connection type permanent magnetic hybrid magnetic levitation device for an attraction type magnetic levitation train. The device comprises permanent magnetic levitation modules and electromagnetic levitation modules mounted on a magnetic levitation train bogie. A given number of permanent magnetic levitation modules and a given number of electromagnetic levitation modules are grouped and then arranged in parallel connection along the F shaped track in a manner of right facing the F shaped track, the width between outer edges of two pole plates of the permanent magnetic levitation modules is larger than the width of the F shaped track, and the width between outer edges of two pole plates of the electromagnetic levitation modules is equal to the width of the F shaped track. With the inventive structure, levitation force generated by the permanent magnetic levitation modules is insusceptible to air gap change, to prevent zero air gap between the permanent magnetic device and the F shaped track, lower difficulty of control on the electromagnet, and improve load carrying capacity of the magnetic levitation train.

Description

Technical field [0001] The invention relates to the technical field of maglev trains, in particular to a permanent-magnet hybrid maglev device for suction-type maglev trains. Background technique [0002] At present, there are three main types of maglev devices for suction-type maglev trains: 1. Single use of electromagnets to generate levitation force, such as HSST maglev trains; 2. Use of electromagnets and superconductors to jointly generate levitation forces; 3. Use of electromagnets and permanent magnets together to generate suspension force. [0003] The method of only using electromagnets to generate levitation force is relatively mature at present, and there are corresponding test trains both at home and abroad. Its disadvantages are high energy consumption and limited load capacity; the method of using electromagnets and superconductors to generate levitation force is currently only a relevant model in the laboratory; its disadvantages are that it needs to consume ...
