Detailed Description
To make the purpose, technical solution and advantages of the present invention clearer, the following will combine the embodiments of the present invention and the corresponding drawings to clearly and completely describe the technical solution of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In order to solve the problem that exists among the prior art, according to the utility model discloses an embodiment provides a running gear of high-speed train in vacuum through the single round to bogie that is used for the high-speed train in vacuum, both can provide suspension and guiding force for the train, can provide the traction force of wheel rail operation again, has light in weight simultaneously and good minor radius curve trafficability ability and climbing ability.
That is, the suspension and guide module, the linear motor and the single-wheel bogie are combined together, so that the light weight of the linear motor bogie is realized, sufficient suspension force and guide force are provided, and high-speed operation in a vacuum pipeline is ensured. The single-wheel-pair bogie can provide suspension force and guiding force for suspension operation for a vacuum high-speed train, simultaneously provides traction force for track operation, and adopts a light-weight design.
In an alternative embodiment, referring to the examples shown in fig. 1 to 5, the running gear of the vacuum high-speed train, the single-wheel-pair bogie and the driving method thereof may include: the device comprises a framework 6, a wheel pair 4, a primary suspension part 3, a secondary suspension part 1, a suspension and guide module 2 and a linear motor rotor 5.
Wherein the wheel set 4 is located below the frame 6 and is connected to the frame 6 by a suspension 3. The secondary suspension member 1 is positioned on the framework 6, and the two suspension and guide modules 2 are respectively positioned on the left side and the right side of the framework 6. And the linear motor rotor 5 is fixed below the framework 6 through the adjusting device and is positioned on the central line of the wheel pair 4. Two sets of single wheel pairs (for example, wheel pairs 4) are arranged at intervals in front and back to form a running mechanism of the train, and a carriage 7 of the train is arranged on the running mechanism through the secondary suspension part 1 and runs on a track 10 through the wheel pairs 4. Meanwhile, the levitation and guidance module 2 is correspondingly positioned on the levitation track 11, and the linear motor mover 5 corresponds to the linear motor stator 9 laid on the central line of the track 10. The entire vehicle runs in a vacuum tunnel 8.
For example: an adjustment device may include: linear electric motor hanging beam. The suspension beam for the linear motor is used for suspending the rotor of the linear motor, has certain adjusting capacity, and can adjust the vertical height of the linear motor according to different use conditions.
Therefore, when the train runs, traction is provided by the linear motor rotor 5 firstly, so that the train can advance on the track 10 in an accelerating mode by the wheel pair 4, when a certain speed required by suspension is reached, the suspension and guide module 2 enables the train to enter a suspension mode through suspension force generated by action with the suspension track 11, and the comfort of the whole train in the running process is ensured by the primary suspension part 3 and the secondary suspension part 1.
The track 10 may be a conventional wheel track, i.e., a railway rail. For example: the levitation track 11 may be a customized track specially used for a vacuum high-speed train, and the cross-sectional structure of the levitation track may refer to an example shown in fig. 4, and the levitation track interacts with the levitation-guidance module through the upper curved surface to generate levitation force, thereby providing the levitation force for the vacuum high-speed train.
For example: the linear motor rotor 5 is suspended under the framework 6 through four groups of adjusting devices, and the two groups of suspension and guide modules 2 extend out of the left side and the right side of the framework 6 to form a two-wing layout. The bogie is fixed with the body of the high-speed train through four groups of secondary suspension parts on the framework 6, and only one group of wheel pairs of the bogie runs on the track.
Wherein, four sets of adjusting device can include: four groups of linear motor suspension beams.
Meanwhile, the linear motor rotor 5 provides traction for the bogie, and when the bogie reaches a certain speed, the suspension and guide modules 2 on the two wings of the bogie provide suspension lifting force and guide force for the train. Therefore, the train can realize wheel rail running and suspension running through the front and rear groups of bogies. Compared with the traditional train layout, the whole train has only two sets of wheel sets, so the train adopting the single-wheel bogie has better small-radius curve passing capacity. Simultaneously, compared with the traditional double-wheel-pair bogie, the single-wheel-pair bogie can more easily realize the radial function of the wheel pair.
Meanwhile, in order to overcome the stability defect of the single-wheel bogie, a snake-shaped shock absorber and a transverse shock absorber are arranged on the framework 6, so that the influence caused by snake-shaped motion is reduced. The single pull rod type balance action rod is adopted, so that the nodding effect caused by a single wheel pair (such as the wheel pair 4) is reduced. And the primary suspension part (such as the primary suspension part 3) adopts a conical metal rubber spring, and the secondary suspension part (such as the secondary suspension part 1) adopts a spiral steel spring, so that the transverse stability and the vertical performance of the bogie are improved, and the dynamic stability is further improved.
Therefore, the technical scheme of the utility model, owing to adopted the single round to the design, less a set of wheel pair than conventional bogie, this bogie can realize the lightweight to the required weight restriction of suspension has been satisfied. Meanwhile, the bogie carries the suspension and guide module and the driving motor, so that the vacuum high-speed train can obtain higher construction speed and excellent climbing capability.
Through a large number of tests, the technical scheme of the utility model is adopted, compared with the traditional bogie, the radial function of the wheel pair is easier to realize, thereby being more beneficial to the curve (especially the small radius curve) to pass through and reducing the wheel-rail acting force and abrasion; and simple structure, lightweight, have good curve trafficability characteristic, low noise, easy to maintain. Meanwhile, the traction mode is linear motor traction, so that the climbing capability is good; and the carried suspension and guide module has suspension capacity, so that the vacuum high-speed train can run in the vacuum pipeline at a higher speed. Furthermore, the safety and the reliability of the vacuum high-speed rail system are improved, the self weight of the train is reduced, and the economical efficiency is enhanced. Moreover, the application prospect is wide, and the method has very wide commercial prospect; not only can fill up the blank of the related technology, but also can generate larger social benefit and economic benefit.
In summary, it is readily understood by those skilled in the art that the advantageous modes described above can be freely combined and superimposed without conflict.
The above description is only an example of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
