Problems solved by technology

[0005] 1) There are many rods in the forced guide mechanism, and the size of the rods is relatively large, which requires a relatively strict geometric relationship between the rods, but each rod is a slender rod, so that the correct assembly relationship between the rods can be maintained. Difficulty, which makes forcing to the actual function suffer greatly
In addition, the adjustment and maintenance of the structure in the later stage are very inconvenient
[0006] 2) The design dimensions of the forced guiding mechanism are obtained based on the fact that the modules are completely on the circular curve. When entering and exiting the transition curve, since the front and rear modules of the forced guiding mechanism are not on the same curve radius, the forced guiding mechanism is in the process of entering and exiting the curve. It will cause a large impact load, which will cause the vehicle body to move laterally and reduce the vehicle's operating comfort
Therefore, if a forced guide mechanism is used, it is also affected by the number of modules
[0008] 4) The structure is relatively complex, especially the extensive use of sliding tables, guide rails and the installation seat structure of the forced guide mechanism arranged on the car body, which are not conducive to the lightweight design of the structure

Embodiment 1

[0034] Such as image 3 As shown, this embodiment provides a medium-low speed maglev running mechanism, including two combined suspension modules 7 , an anti-roll beam module 9 , a bracket air spring 10 , two parallelogram support modules 8 and a traction rod 11 .

[0035] The two combined suspension modules 7 are respectively located on both sides of the track, and this embodiment adopts the structure of four sets of suspension units (four suspension units on the left and right, a total of eight suspension units). That is, each combined suspension module 7 includes two end suspension units 701 and two middle suspension units 702. The upper suspension unit 701 and the middle suspension unit 702 are connected together through the joint unit 703 in turn. Both the end suspension unit 701 and the middle suspension unit 702 are equipped with suspension electromagnets, traction motors, brakes and other structures, which are the source of the vertical load, lateral load and longitud...

Embodiment 2

[0047] Such as Figure 7 As shown, the present embodiment adopts a singular suspension unit structure, and five groups of suspension units (five groups of suspension units on the left and right sides) are provided in this case. Its main structure is basically the same as that of Embodiment 1, and the difference is that two end suspension units 701 and three middle suspension units 702 are combined by joint units 703 to form a combined suspension module 7 . Two anti-roll beam modules 9 are installed front and rear between the end suspension units 701 corresponding to the left and right positions, and one anti-side roll beam module 9 is installed in the middle of the middle suspension unit 702 .

Abstract

The invention relates to a medium-low speed maglev running mechanism, which includes two combined suspension modules, an anti-side roll beam module, a bracket air spring and two parallelogram support modules. The two combined suspension modules are respectively located on both sides of the track. The two ends of the anti-roll beam module are respectively connected to the combined suspension modules on both sides, the two parallelogram support modules are straddled on the two combined suspension modules through bracket air springs, and the car body of the medium and low speed maglev train is fixed on the Two parallelogram support modules. Compared with the prior art, the present invention ensures the straight and curved running of the vehicle; there is a bracket air spring between the parallelogram support module and the combined suspension module, therefore, the suspension module is better decoupled; the parallelogram support module is also used to realize vehicle Uniform distribution of body lateral load and vertical load; at the same time, it overcomes various problems caused by the use of forced guiding mechanism in the existing structure.

Description

technical field [0001] The invention relates to the technical field of rail transit vehicles, in particular to a medium-low speed maglev running mechanism. Background technique [0002] The medium and low speed maglev train is a new type of rail transportation. It uses electromagnetic attraction to keep a gap of 8-10mm between the vehicle's suspension magnet and the track. As a part of the vehicle, the running mechanism is located between the car body and the track. It is used to realize the functions of vehicle suspension, guidance, traction, braking and running, and is the most important core component of the vehicle. Different from traditional railway vehicles, the running mechanism is continuously arranged at the bottom of the car body, which puts forward higher requirements for the connection between the running mechanism and the car body. On the one hand, it must ensure the normal straight and curved running posture requirements. On the other hand, it is necessary to ...
