Description

technical field [0001] The invention mainly relates to the field of maglev vehicles, in particular to a suspension guide and traction device for maglev trains. Background technique [0002] The longitudinal non-contact suspension, horizontal non-contact guidance and non-contact traction along the track direction of the maglev train are its three basic functions, which are usually realized by the suspension system, guidance system and traction system. If the three major systems are independent, the maglev train will have a large volume and weight, complex structure, and high cost. Therefore, it is usually necessary to integrate these functions to a certain extent. Currently, conventional structures include HSST low-speed maglev trains and TR-type high-speed maglev trains. [0003] The HSST maglev train adopts a U-shaped electromagnet and an inverted U-shaped track structure. By actively controlling the movement in the direction of suspension, the movement in the direction of...

Problems solved by technology

However, in order to realize the guidance function, the system has added a set of guidance system composed of guidance electromagnet, guidance controller and corresponding power supply equipment. consumption will increase

In addition, the geometric constraints between the guide electromagnet and the track lead to a relatively large limit on its turning radius. If the turning radius is small, the guide electromagnet will collide with the track

In general, the TR-type maglev train integrates the suspension and traction systems, but the guidance system is independent
