Description

Technical Field

[0001] The present invention relates to a maglev vehicle, and particularly to a maglev vehicle suspension frame, a vehicle and a maglev transportation system. Background Art

[0002] At present, the maximum operating speed of medium and low speed maglev vehicles is 160 km / h. In order to continuously improve the competitiveness of medium and low speed maglev transportation, further speed increase is crucial. Among them, improving the traction power and efficiency of linear motors is the key to vehicle speed increase.

[0003] As Figure 1 shown, the existing medium and low speed maglev transportation system adopts an orbital type of track beam a - rail sleeper b - F rail c. The F rail c and the induction plate d are located between the linear motor e and the electromagnet f. When the electromagnet f attracts the F rail c to move upward, the linear motor e also moves upward, and the air gap between the linear motor e and the induction plate d increases, which will reduce the traction efficiency of the linear motor e. In addition, vertical support devices h are provided at both ends of the existing vehicle suspension frame g, which limits the length of the linear motor e and is not conducive to increasing the power of the linear motor e.

[0004] Chinese Patent Application CN113954652A proposes a scheme of embedding a linear motor inside an electromagnet. The track is a C - type rail, and an induction plate is arranged inside, so that the normal force and displacement directions of the linear motor and the electromagnet relative to the induction plate and the magnetic pole are the same. However, it is difficult to dissipate heat from the electromagnet and the linear motor, and water cooling is required, making the overall structure complex and increasing the weight and cost of the vehicle.

[0005] Therefore, there is an urgent need for a medium and low speed maglev vehicle with a simple structure, low cost, high traction efficiency and higher speed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a maglev vehicle suspension frame, a vehicle and a maglev transportation system, which are used to improve the traction efficiency and vehicle speed of maglev vehicles.

The electromagnet is installed below the second longitudinal beam. The second longitudinal beam and the electromagnet are connected through the second support arm.

[0013] A further improvement of the above solution is that a vertical support unit is installed below the end of the first longitudinal beam, and the first support arm is installed below the end of the first cross beam.

[0014] A further improvement of the above solution is that the traction suspension module is installed above the lower end of the first support arm. The lower end of the first support arm extends into the electromagnet base. A rubber stack is installed in the electromagnet base. The traction suspension module is seated on the first support arm through the rubber stack.

[0015] A further improvement of the above solution is that second pull rods are provided at both ends of the second longitudinal beam. The second pull rods are arranged parallel to the second longitudinal beam. One end of the second pull rod is installed on the second support arm, and the other end is installed on the first support arm.

[0016] A further improvement of the above solution is that swing rods are provided at both ends of the second longitudinal beam. The swing rods are arranged perpendicular to the second longitudinal beam. One end of the swing rod is installed on the second longitudinal beam, and the other end is installed on the first support arm.

[0017] A further improvement of the above solution is that the air spring is installed above both ends of the first cross beam, and the bottom of the air spring is connected to the first cross beam.
