Description

Technical Field

[0001] This utility model relates to the field of monorail transportation technology, and more specifically, to a suspension system based on superconducting pinned magnetic levitation. Background Technology

[0002] In the transportation sector, with the acceleration of urbanization and the increasing demand for efficient, convenient, and green travel, traditional modes of transportation face numerous challenges. While urban rail transit has alleviated surface traffic pressure to some extent, traditional rail transit systems such as subways and light rail suffer from high construction costs, long construction periods, and significant impacts on the surface environment. For example, subway construction requires large-scale underground excavation, which is not only technically challenging but also damages underground pipelines and geological structures, while also causing some disruption to the lives of nearby residents.

[0003] To address these issues, suspended trains were developed. In suspended trains, the train's suspension frame assembly uses guide wheels to work with the track beam to guide the train. However, the guide wheels cause wear on the track beam, resulting in a short service life for the track beam. Furthermore, after prolonged operation, wear on the guide wheels and dents or scratches caused by the guide wheels on the track beam can lead to inaccurate train guidance. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0026] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this utility model, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] like Figures 1-4 As shown, this embodiment provides a suspension system based on superconducting pinned magnetic levitation, including: a track beam 10, a suspension frame assembly 20, and a vehicle body 30. The track beam 10 is provided with a mounting surface perpendicular to its own height direction, and a permanent magnet track structure 131 is laid on the mounting surface. The suspension frame assembly 20 is provided with a mounting part located above the mounting surface, and the mounting part is directly opposite to the permanent magnet track structure 131. A levitation device 40 is provided on the side of the mounting part facing the permanent magnet track structure 131. The vehicle body 30 is located below the track beam 10 and is connected to the suspension frame assembly 20.

[0028] In some embodiments, the track beam 10 is provided with a mounting surface, which is perpendicular to the height direction of the track beam 10. A permanent magnet track structure 131 is laid on the mounting surface of the track beam 10. The permanent magnet track structure 131 can be a permanent magnet plate. The permanent magnet track structure 131 generates a stable magnetic field. The suspension frame assembly 20 is provided with a mounting part located above the mounting surface and facing the mounting surface. A levitation device 40 is provided on the side of the mounting part of the suspension frame assembly 20 facing the permanent magnet track structure 131. The levitation device 40 can be a Dewar. The levitation device 40 contains superconducting material. The suspension frame assembly 20 is connected to the vehicle body 30 located below the track beam 10.

[0029] It is understandable that when a superconducting material is cooled to below the critical temperature and enters the superconducting state, according to the perfect diamagnetism of the superconductor, the superconductor will generate an induced current in the surrounding space. The magnetic field generated by the induced current repels the magnetic field generated by the permanent magnet track structure 131, thereby suspending the suspension frame assembly 20 and the vehicle body 30 connected to it, achieving non-contact support.

[0030] It should be noted that the magnetic field generated by the permanent magnet track structure 131 of this application has a specific distribution in space. When the vehicle body 30 deviates laterally during operation, the force generated by the interaction between the induced current generated by the superconducting material in the suspender 40 and the magnetic field will change. This change will form a restoring force, pulling the vehicle body 30 back to the correct running track, thereby realizing the guiding function. At the same time, the magnitude and direction of the guiding force can be precisely controlled to ensure that the vehicle body 30 runs stably and accurately along the track.

[0031] Compared to traditional guide wheel designs, this application can ensure precise guidance of the car body 30 while avoiding damage such as dents and scratches on the surface of the track beam 10, thereby extending the service life of the track beam 10. Furthermore, the car body 30 of this application still maintains precise guiding performance after long-term operation.

[0032] Of course, the non-contact method between the suspension frame assembly 20 and the track beam 10 in this application avoids the generation of debris and frictional heat, reduces the adverse effects of environmental factors on the track beam 10, further ensures the long-term stable operation of the track beam 10, and extends the service life of the track beam 10.

[0033] According to the superconducting pinned magnetic levitation suspension system of this utility model, a permanent magnet track structure 131 is set on the mounting surface of the track beam 10, and a levitation device 40 is set on the suspension frame assembly 20 facing the permanent magnet track structure 131, thereby realizing the levitation operation of the vehicle body 30. During the operation of the vehicle body 30, the suspension frame assembly 20 and the track beam 10 are completely non-contact, avoiding mutual wear between the suspension frame assembly 20 and the track beam 10, extending the service life of the suspension frame assembly 20 and the track beam 10. At the same time, the vehicle body 30 can still maintain precise guiding performance after long-term operation.

[0034] According to some embodiments of the present invention, multiple suspension frame assemblies 20 and a vehicle body 30 are constructed together to form a carriage. Multiple suspension frame assemblies 20 are respectively disposed on the top of the vehicle body 30, and the multiple suspension frame assemblies 20 are spaced apart along the extension direction of the vehicle body 30. The carriage is constructed as multiple carriages along the extension direction of the track beam 10, and two adjacent carriages are connected to each other.

[0035] In some embodiments, multiple suspension frame assemblies 20 are respectively disposed on the top of the vehicle body 30, providing suspension support and guidance for the vehicle body 30 in its extending direction, reducing swaying and tilting of the vehicle body 30, and maintaining balance and stability of the vehicle body 30 during operation. The vehicle body 30 is constructed as multiple units extending along the track beam 10, and adjacent vehicle bodies 30 are connected to each other; that is, multiple vehicle bodies 30 can form a complete train formation to increase passenger capacity.

[0036] It is worth mentioning that the connection between the car bodies 30 is usually achieved using mechanical connection devices, such as connecting hooks and connecting pins, to ensure that the car bodies 30 do not separate during operation, while also transmitting traction and braking forces to ensure the synchronous operation of the entire train formation. It should be noted that this can be: multiple car bodies 30 connected through each other; some car bodies 30 connected through each other; or multiple car bodies 30 not connected through each other; there is no limitation here.

[0037] According to some embodiments of the present invention, the track beam 10 includes a mounting beam 14, and first vertical beams 15 are respectively provided on both sides of the mounting beam 14 in the width direction. The free ends of the first vertical beams 15 extend toward the vehicle body 30 and are provided with connecting beams 16. That is, the extension direction of the two first vertical beams 15 is parallel to the height direction of the track beam 10, the free ends of the two connecting beams 16 extend toward each other, and the side of the two connecting beams 16 facing the mounting beam 14 is respectively constructed as a mounting surface.

[0038] In some embodiments, the above configuration can enable the track beam 10 to form an arch-like structure, that is, the track beam 10 has an installation space that opens to the bottom, part of the suspension frame assembly 20 is disposed in the installation space, and another part of the suspension frame assembly 20 is disposed outside the installation space and connected to the vehicle body 30.

[0039] The free ends of the two connecting beams 16 extend toward each other and are respectively provided with mounting surfaces. Permanent magnet track structures 131 are laid on the two mounting surfaces. The suspension frame assembly 20 is provided with two mounting parts that are respectively opposite to the two mounting surfaces. The two mounting parts are respectively provided with levitation devices 40 that are opposite to the corresponding permanent magnet track structures 131. Thus, the two sides of the vehicle body 30 in the width direction are supported, making the cooperation between the vehicle body 30 and the track beam 10 more stable, thereby making the operation of the vehicle body 30 more stable.

[0040] According to some embodiments of the present invention, the track beam 10 includes at least one second vertical beam 11. At least one second vertical beam 11 has a first horizontal beam 12 and a second horizontal beam 13 respectively provided at both ends in its height direction. The first horizontal beam 12 is located above the second horizontal beam 13. The side surface of the second horizontal beam 13 facing the first horizontal beam 12 is divided into two mounting surfaces by at least one second vertical beam 11.

[0041] In some embodiments, the first crossbeam 12, the second crossbeam 13 and at least one second vertical beam 11 are connected to each other so that the track beam 10 forms an "I" shaped structure to help distribute and bear various forces and ensure that the track beam 10 will not be deformed or damaged during the operation of the maglev transportation system.

[0042] The two mounting surfaces formed by the second vertical beam 11 provide a precise positional reference for the laying of the permanent magnet track structure 131. During installation, the permanent magnet track structure 131 can be easily and accurately laid on the mounting surface, ensuring the relative positional accuracy between the permanent magnet track structure 131 and the subsequent levitation device 40, thereby ensuring that the superconducting pinned magnetic levitation effect can be properly exerted and improving the levitation and guidance performance of the magnetic levitation system.

[0043] It is understandable that the above-mentioned arrangement in this application makes the cooperation relationship between the track beam 10 and the suspension frame assembly 20 visible, which can avoid construction personnel from crawling into the track beam 10 to install, inspect and maintain the permanent magnet track structure 131, thereby improving the convenience of installation and maintenance of the suspension system.

[0044] According to some embodiments of this utility model, the suspension frame assembly 20 includes two first mating beams 21. The extending direction of the first mating beams 21 is parallel to the extending direction of the track beam 10. A levitation device 40 is provided on the side of the first mating beams 21 facing the permanent magnet track structure 131. The two first mating beams 21 are respectively connected to the vehicle body 30 through first connecting arms 23. In this embodiment, the first mating beams 21 are constructed as mounting parts. In this case, the suspension frame assembly 20 is a single-layer structure (the suspension frame assembly 20 only includes the first mating beams 21).

[0045] According to some embodiments of the present invention, the bottom ends of the two first mating beams 21 are respectively connected to the second mating beams 22. The second mating beams 22 are constructed as the mounting parts. A suspender 40 is provided on the side of the second mating beams 22 facing the permanent magnet track structure 131. At this time, the suspension frame assembly 20 is a double-layer structure (the suspension frame assembly 20 includes the first mating beams 21 and the second mating beams 22 located below the first mating beams 21).

[0046] In some embodiments, the suspension frame assembly 20 uses two first cooperating beams 21 as the main frame components. The extension direction of the first cooperating beams 21 is parallel to the extension direction of the track beam 10, and second cooperating beams 22 are respectively provided at both ends of the bottom of the first cooperating beams 21. The extension direction of the second cooperating beams 22 is also parallel to the extension direction of the first cooperating beams 21, and a suspender 40 is provided at the bottom of the second cooperating beams 22.

[0047] It is understandable that, since the extension direction of the car body 30 is also parallel to the extension direction of the track beam 10, the extension directions of the first mating beam 21, the second mating beam 22 and the car body 30 are parallel to each other, so that the second mating beam 22 can cooperate with the car body 30 in the extension direction of the car body 30, so that the car body 30 can be stably stressed in its own extension direction, thereby ensuring the stability of the cooperation between the car body 30 and the track beam 10, and thus ensuring the operational stability of the car body 30.

[0048] It should be noted that since one vehicle body 30 corresponds to multiple suspension frame assemblies 20, and the multiple suspension frame assemblies 20 are respectively set on the top of the vehicle body 30, in the extension direction of the vehicle body 30, the two sides of the vehicle body 30 in the width direction are respectively connected with the track beam 10 through multiple spaced second mating beams 22, which ensures that the vehicle body 30 can stably cooperate with the track beam 10.

[0049] According to some embodiments of the present invention, the second mating beam 22 is connected to a second connecting arm 24 extending toward the vehicle body 30. The second connecting arm 24 connected to the multiple second mating beams 22 is connected by a connecting bracket, which is located between the vehicle body 30 and the track beam 10.

[0050] In some embodiments, a plurality of second mating beams 22 are respectively connected to second connecting arms 24, and the plurality of second connecting arms 24 extend toward the vehicle body 30. A mounting bracket is provided between the vehicle body 30 and the track beam 10. The mounting bracket is suitable for connecting the plurality of second connecting arms 24, thereby improving the setting stability of the plurality of second mating beams 22 and ensuring the mating stability of the vehicle body 30 and the track beam 10.

[0051] It is worth mentioning that the mounting bracket can be a longitudinal beam adapted to connect multiple second connecting arms 24 within a suspension frame assembly 20.

[0052] According to some embodiments of the present invention, a damping member 26 is provided between the first mating beam 21 and the two second mating beams 22, and the top of the damping member 26 is connected to the first mating beam 21, and the bottom of the damping member 26 is connected to the second mating beams 22.

[0053] In some embodiments, the damper 26 may be an air spring, a rubber stack, or a spring damper, etc., and there is no limitation herein. The damper 26 is disposed between the first mating beam 21 and the two second mating beams 22. When vibration is transmitted upward from the second mating beams 22 (which interacts with the track beam 10 to generate magnetic levitation force and is also easily affected by external vibrations) to the first mating beams 21 and thus affect the vehicle body 30, or from the vehicle body 30 to the second mating beams 22 through the first mating beams 21, the damper 26 can play a buffering role. Specifically, the damper 26 absorbs and dissipates vibration energy through its own elastic deformation, reducing the amplitude and speed of vibration transmission, thereby reducing the impact of vibration.

[0054] It is worth mentioning that the damping component 26, while connecting the first mating beam 21 and the second mating beam 22, also participates in the mechanical balance of the entire suspension frame assembly 20. Specifically, in both stationary and running states, the damping component 26 can deform appropriately according to the load borne by the suspension frame assembly 20 (such as the weight of the car body 30, magnetic levitation force, etc.), adjusting the relative positional relationship between the first mating beam 21 and the second mating beam 22, so that the entire suspension frame assembly 20 is in a relatively stable mechanical equilibrium state, ensuring the stabilizing effect of the magnetic levitation force and the smooth levitation of the car body 30.

[0055] According to some embodiments of the present invention, a first emergency wheel 27 is provided on the side of the suspension frame assembly 20 facing the mounting surface. The distance from the first emergency wheel 27 to the mounting surface is L1, and the distance between the suspender 40 and the permanent magnet track structure 131 is L2, satisfying: L1 < L2.

[0056] In some embodiments, the suspension system based on superconducting pinned magnetic levitation normally relies on the levitation device 40 (containing superconducting blocks, etc., which generates magnetic levitation force with the permanent magnet track structure 131) to levitate the vehicle body 30. When the magnetic levitation system malfunctions, such as the levitation device losing temperature or the superconducting blocks losing levitation force, resulting in the disappearance or insufficiency of the magnetic levitation force, the vehicle body 30 and the suspension frame assembly 20 will begin to fall due to gravity.

[0057] Since the distance L1 between the first emergency wheel 27 and the mounting surface is less than the distance L2 between the levitation device 40 and the permanent magnet track structure 131, when the magnetic levitation fails, after the vehicle body 30 and the suspension frame assembly 20 fall a certain distance, the first emergency wheel 27 will contact the mounting surface (track beam 10 or related support structure surface) before the levitation device 40. At this time, the first emergency wheel 27 will bear the weight of the vehicle body 30, provide emergency support for the vehicle body 30, and prevent the levitation device 40 from directly contacting the mounting surface and being damaged.

[0058] Of course, when the vehicle body 30 or the suspension frame assembly 20 needs maintenance, the presence of the first emergency wheel 27 will also prevent the suspension 40 from directly contacting the permanent magnet track structure 131, thereby facilitating the maintenance of the suspension 40 and preventing the suspension 40 from bearing the weight of the vehicle body 30, thus preventing damage to the suspension 40.

[0059] According to some embodiments of the present invention, the suspension frame assembly 20 is further provided with a second emergency wheel 28, which can selectively cooperate with the track beam 10 in the width direction of the track beam 10.

[0060] In some embodiments, when the vehicle body 30 is running and experiencing strong lateral winds, the second emergency wheel 28 can cooperate with the track beam 10 to achieve auxiliary guidance. At the same time, it can prevent the suspension 40 and the suspension frame assembly 20 from directly contacting the second vertical beam 11, thereby preventing the suspension 40, the suspension frame assembly 20 and the track beam 10 from wearing each other, improving the operating safety factor of the vehicle body 30 and the service life of the suspension system.

[0061] It is worth mentioning that a first traction unit 132 is provided on the side of the track beam 10 facing the car body 30, and a second traction unit 31 is provided on the side of the car body 30 facing the track beam 10. The first traction unit 132 and the second traction unit 31 cooperate to provide driving force for the car body 30, so as to drive the car body 30 to move along the extension direction of the track beam 10.

[0062] In some embodiments, the first traction part 132 is constructed as an aluminum induction plate laid along the extension direction of the track beam 10, and the second traction part 31 is constructed as a coil.

[0063] When an alternating current is passed through the coil of the second traction unit 31, an alternating magnetic field will be generated around the coil according to the law of electromagnetic induction. Since the first traction unit 132 is an aluminum induction plate laid along the extension direction of the track beam 10, when the car body 30 drives the coil to move, causing the coil to approach or move away from the aluminum induction plate, the aluminum induction plate will be in an alternating magnetic field. According to the mutual inductance phenomenon of electromagnetic induction, an induced electromotive force and an induced current, i.e. eddy current, will be generated in the aluminum induction plate.

[0064] The eddy currents generated in the aluminum induction plate will form a magnetic field that interacts with the magnetic field of the coil. According to Ampere's law, these two magnetic fields will generate an interaction force, namely electromagnetic force. Electromagnetic force is the driving force that drives the vehicle body 30 to move. The direction of electromagnetic force is related to the direction of movement of the vehicle body 30. By controlling the frequency, phase and other parameters of the alternating current in the coil, the magnitude and direction of electromagnetic force can be precisely controlled, thereby realizing the driving, braking and control of the movement of the vehicle body 30.

[0065] It is worth mentioning that a power supply rail is provided on the side of the first crossbeam 12 facing the second crossbeam 13. The extension direction of the power supply rail is parallel to the extension direction of the track beam 10. A current collector 50 is provided on the first mating beam 21. The current collector 50 cooperates with the power supply rail and is electrically connected to the coil. Thus, the power supply rail and the current collector 50 cooperate to supply power to the coil, thereby ensuring that the car body 30 can move along the extension direction of the track beam 10.

[0066] In other embodiments, the first traction part 132 is configured as a coil arranged along the extension direction of the track beam 10, and the second traction part 31 is configured as a permanent magnet.

[0067] The permanent magnet itself has a stable magnetic field. When the vehicle body 30 moves the permanent magnet, causing it to approach or move away from the coil, the magnetic field of the permanent magnet will pass through the coil. According to Faraday's law of electromagnetic induction, when the magnetic flux in the coil changes, an induced electromotive force will be generated in the coil, accompanied by an induced current.

[0068] The induced current generated in the coil creates a magnetic field that interacts with the permanent magnet's magnetic field. According to Ampere's law, these two magnetic fields generate an interaction force, namely the electromagnetic force. This electromagnetic force is the driving force that propels the vehicle body 30. By designing the number of turns and winding method of the coil, as well as the magnetic field strength and distribution of the permanent magnet, the magnitude and direction of the electromagnetic force can be precisely controlled, thereby achieving the driving and control of the vehicle body 30's movement. For example, when the vehicle body 30 needs to accelerate, relevant parameters can be adjusted to make the direction of the electromagnetic force the same as the direction of the vehicle body 30's movement and increase its magnitude; when the vehicle body 30 needs to decelerate, the direction of the electromagnetic force is adjusted to be opposite to the direction of the vehicle body 30's movement.
