[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] 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 invention, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1-6 As shown, this embodiment provides a high-temperature superconducting magnetic levitation vehicle system, including: a track 10, a frame 20, and a levitation assembly 30. The track 10 is provided with a permanent magnet plate. The top of the frame 20 is connected to the vehicle body. Mounting parts 21 are respectively provided at both ends of the frame 20 in the length direction. The levitation assembly 30 is constructed as a plurality of components corresponding to and connected to the mounting parts 21. The levitation assembly 30 is adapted to rotate relative to the mounting parts 21 in the horizontal and / or vertical directions. The levitation assembly 30 cooperates with the permanent magnet plate to achieve vehicle body levitation.

[0032] In some embodiments, a permanent magnet plate is provided on the track 10 to generate a stable magnetic field. The permanent magnet plate is adapted to cooperate with the levitation assembly 30 to achieve the levitation of the levitation assembly 30, thereby achieving the levitation of the vehicle body. The top of the frame 20 is connected to the vehicle body. Mounting portions 21 are provided at both ends of the frame 20 in the length direction. The mounting portions 21 are structures for connecting the levitation assembly 30. The mounting portions 21 are adapted to provide a fixed position for the installation of the levitation assembly 30. There are multiple levitation assemblies 30, and the multiple levitation assemblies 30 correspond one-to-one with the mounting portions 21 at both ends of the frame 20 and are connected.

[0033] The suspension assembly 30 can rotate relative to the mounting part 21 in the horizontal and / or vertical directions. That is, the suspension assembly 30 can rotate relative to the mounting part 21 in the horizontal direction to improve the vehicle's steering ability in the horizontal direction. The suspension assembly 30 can also rotate relative to the mounting part 21 in the vertical direction so that when the vehicle passes through the uphill or downhill sections with a small vertical curve radius, the suspension assembly 30 can rotate in the vertical direction along with the rise or fall of the track 10. This allows the suspension assembly 30 to stably cooperate with the permanent magnet plate on the track 10, thereby improving the vehicle's levitation ability and preventing the suspension assembly 30 from colliding with the permanent magnet plate.

[0034] Understandably, the permanent magnet plate set on track 10 generates a stable magnetic field, and the levitation assembly 30 contains high-temperature superconducting material. When the vehicle is in operation, the levitation assembly 30 approaches the magnetic field generated by the permanent magnet plate, and the high-temperature superconducting material enters the superconducting state. According to the Meissner effect, the superconductor will generate an induced current on its surface. The magnetic field generated by the induced current interacts with the magnetic field of the permanent magnet plate, thereby generating an upward levitation force, which makes the vehicle levitate at a certain height above track 10.

[0035] Since the suspension assembly 30 can rotate horizontally and / or vertically relative to the mounting part 21, when the vehicle is running and encounters a horizontal turn, the suspension assembly 30 can rotate horizontally relative to the mounting part 21 to ensure that the vehicle has a stable suspension force when turning. When the vehicle is running and passes through uphill or downhill sections with a small vertical curve radius, the suspension assembly 30 can rotate vertically relative to the mounting part 21 to enable the suspension assembly 30 to stably cooperate with the permanent magnet plate on the track 10, thereby improving the vehicle's suspension ability and preventing the suspension assembly 30 from colliding with the permanent magnet plate.

[0036] According to the high-temperature superconducting magnetic levitation vehicle system of the present invention, the levitation assembly 30 is adapted to rotate relative to the mounting part 21 in the horizontal and / or vertical directions. As a result, the vehicle body has a stable levitation force when passing through horizontal curves, thereby ensuring the stable levitation operation of the vehicle body, reducing the influence of lateral forces, and improving the safety and comfort of the vehicle body. At the same time, when the vehicle body passes through uphill or downhill sections with a small vertical curve radius, the levitation assembly 30 can also stably cooperate with the permanent magnet plate on the track 10 to improve the vehicle body's levitation ability through the vertical curve radius and avoid collision between the levitation assembly 30 and the permanent magnet plate.

[0037] According to some embodiments of the present invention, the suspension assembly 30 includes a central shaft 311 extending along the height direction of the vehicle body. One end of the central shaft 311 is rotatably connected to the mounting part 21, and the other end of the central shaft 311 is connected to a mounting plate 32 via a first radial bearing 312. The bottom of the mounting plate 32 is connected to the suspension body 33, and the top of the mounting plate 32 is connected to two sets of first side bearing wheel assemblies 34. The two sets of first side bearing wheel assemblies 34 are respectively disposed at both ends of the mounting plate 32 in the length direction via elastic members 35.

[0038] In some embodiments, the central shaft 311 extends along the height direction of the vehicle body, one end of the central shaft 311 is rotatably connected to the mounting portion 21 on the frame 20, and the mounting plate 32 is connected to the other end of the central shaft 311 through the first radial bearing 312. Thus, the mounting plate 32 can rotate in the horizontal direction relative to the mounting portion 21 through the above arrangement, thereby realizing the rotation of the suspension body 33 in the horizontal direction relative to the mounting portion 21.

[0039] Two sets of first side bearing wheel assemblies 34 are respectively disposed at both ends of the mounting plate 32 along its length, and the first side bearing wheel assembly 34 is connected to the mounting plate 32 through an elastic element 35. The elastic element 35 can be a spring sheet or a pad made of elastic rubber material, etc. The elastic element 35 is adapted to deform when the first side bearing wheel assembly 34 moves in the vertical direction relative to the mounting plate 32.

[0040] Understandably, when the two sets of first side bearing wheel assemblies 34 are on the horizontal track 10, the elastic members 35 push the first side bearing wheel assemblies 34 up to contact the mounting part 21, thereby sharing part of the vehicle body's load. When climbing, the suspension height of the front end of the suspension body 33 is lower, and the force on the front first side bearing wheel assembly 34 is greater than that on the rear first side bearing wheel assembly 34. As a result, the elastic member 35 at the front end is compressed to a greater extent than the elastic member 35 at the rear end. At this time, the suspension assembly 30 can adjust its front end upwards according to the top surface of the track 10 to adapt to the vertical curve radius of the track 10. It is worth mentioning that suspension assemblies 30 are respectively provided at both ends of the length direction of the frame 20. Therefore, under the action of the two elastic members 35 of the two suspension assemblies 30 at the front and rear of the frame 20, the vehicle body has a better ability to adapt to the vertical curve radius of the track 10.

[0041] In other embodiments, the inner ring of the first radial bearing 312 is connected to the central shaft 311, the outer ring of the first radial bearing 312 is spherically fitted to the inner ring of the first radial bearing 312, and the outer ring of the first radial bearing 312 is connected to the mounting plate 32. Thus, the vertical degree of freedom between the mounting plate 32 and the central shaft 311 can also be released, thereby allowing the mounting plate 32 to further release the vertical degree of freedom relative to the mounting part 21, so as to further improve the vehicle body's ability to adapt to the vertical curve radius of the track 10.

[0042] According to some embodiments of the present invention, the first side bearing assembly 34 includes a mounting frame 341, which is connected to the mounting plate 32. The mounting frame 341 is connected to a first roller 343 via a second radial bearing 342. The rolling direction of the first roller 343 is parallel to the tangent of a circle centered on the axis of the central shaft 311.

[0043] In some embodiments, the mounting bracket 341 is provided with a first rotating rod extending in the horizontal direction. The axis of the first rotating rod intersects the axis of the central shaft 311. The outer ring and the inner ring of the second radial bearing 342 are spherically fitted. The inner ring of the second radial bearing 342 is connected to the first rotating rod, and the outer ring of the second radial bearing 342 is connected to the first roller 343. Thus, the rolling direction of the first roller 343 is parallel to the tangent of the circle centered on the axis of the central shaft 311.

[0044] It is understandable that the rolling direction of the first roller 343 is parallel to the tangent of the circle centered on the axis of the central shaft 311, so that when the mounting plate 32 rotates relative to the mounting part 21, the multiple first rollers 343 can continuously abut against the mounting part 21, thereby ensuring that when the vehicle body rotates in the horizontal direction, the suspension assembly 30 can stably provide support for the vehicle body, thereby ensuring the steering stability of the vehicle body.

[0045] It is worth mentioning that the first roller 343 is connected to the first rotating rod through the second radial bearing 342. Thus, the first roller 343 can rotate freely around the center of the second radial bearing 342 in any direction. In this way, even if there are some errors in the installation of the first side bearing assembly 34, the first roller 343 can rotate flexibly without slippage through the above-mentioned arrangement, making the installation of the first side bearing assembly 34 more convenient.

[0046] In other embodiments, the two sets of first side bearing wheel assemblies 34 each include two first side bearing wheel assemblies 34, with the two first side bearing wheel assemblies 34 of each set of first side bearing wheel assemblies 34 located on both sides of the width direction of the mounting plate 32.

[0047] According to some embodiments of the present invention, two second side bearing roller assemblies 36 are further provided on the top of the mounting plate 32. Both second side bearing roller assemblies 36 are located between two sets of first side bearing roller assemblies 34, and are situated on both sides of the central shaft 311. Each second side bearing roller assembly 36 includes a second roller, the rolling direction of which is parallel to the length direction of the mounting plate 32. It is understood that the arrangement of the two second side bearing roller assemblies 36 can further improve the cooperation between the mounting plate 32 and the mounting part 21, and enhance the support effect on the mounting part 21. Simultaneously, the arrangement of the two second side bearing roller assemblies 36 can constrain the rolling of the mounting plate 32 relative to the mounting part 21 along the width direction of the mounting plate 32 (constraining the left-right rolling of the mounting plate 32).

[0048] According to some embodiments of the present invention, there are two levitation bodies 33, which are arranged sequentially along the length of the mounting plate 32.

[0049] Understandably, considering the passability of small-radius curves, cryogenic levitation devices are generally considered to be in two sets in the longitudinal direction (one set in front and one set in the back, symmetrically arranged left and right). If more sets are arranged in the longitudinal direction, the lateral movement of the cryogenic levitation devices needs to be considered. Current technology generally uses one cryogenic levitation device per set. When the weight to be levied is heavy, the length of the levitation device is generally increased. The longer the length, the greater the load-bearing capacity. Due to the process characteristics of cryogenic levitation devices, they cannot be made too long.

[0050] Preferably, the two levitation bodies 33 are arranged at intervals along the length of the mounting plate 32. Thus, the gap between the two levitation bodies 33 can provide installation space for the larger levitation body 33, avoiding interference between the two large levitation bodies 33.

[0051] This application solves both the length and load-bearing issues by replacing one long levitation device with two short levitation device bodies 33, while also minimizing the impact on curve clearance.

[0052] According to some embodiments of the present invention, an elastic pad 37 is provided at the bottom of the mounting plate 32, a connecting plate 38 is provided at the bottom of the elastic pad 37, and two assembly plates 39 spaced apart along the length of the mounting plate 32 are provided at the bottom of the connecting plate 38. The two assembly plates 39 correspond to and are connected to the two levitation bodies 33 respectively.

[0053] In some embodiments, the elastic pad 37 can buffer the vibration between the suspension body 33 and the frame 20, thereby improving the vibration reduction effect of the vehicle body and thus improving ride comfort. At the same time, at least a portion of the elastic pad 37 can deform when the vehicle body passes through the vertical curve radius, so as to further improve the adaptability of the vehicle body to the vertical curve radius.

[0054] In other embodiments, the mounting plates 39 are rigid components, in which case the two mounting plates 39 are respectively adapted to provide mounting positions for the two suspension bodies 33. Preferably, the mounting plates 39 are flexible components, that is, the mounting plates 39 are made of flexible materials such as rubber. In this case, the two mounting plates 39 can deform when the vehicle body passes through the vertical curve radius, so as to further improve the vehicle body's adaptability to the vertical curve radius.

[0055] According to some embodiments of the present invention, the bottom of the frame 20 is provided with two sets of third rollers 22, the two sets of third rollers 22 are distributed at intervals along the width direction of the frame 20, the track 10 is provided with a lifting mechanism 40 located at the station, the lifting mechanism 40 is provided with a support part adapted to move in the vertical direction, and the support part is adapted to cooperate with the third rollers 22.

[0056] In some embodiments, the vehicle body needs to be supported by the lifting mechanism 40 when it is located at the station to prevent the levitation body 33 from contacting the permanent magnet plate and causing damage to the levitation body 33. The support part of the lifting mechanism 40 is adapted to cooperate with the third roller 22 to support the vehicle body. It is worth mentioning that the rolling direction of the third roller 22 is parallel to the width direction of the frame 20.

[0057] Understandably, the frame 20 cooperates with the support through the third roller 22 to reduce the friction between the frame 20 and the lifting mechanism 40, thereby reducing the wear of the frame 20 and / or the lifting mechanism 40, and thus extending the service life of the frame 20 and / or the lifting mechanism 40.

[0058] In the prior art, the frame is equipped with two sets of V-blocks, and the lifting mechanism is equipped with two sets of stop blocks corresponding to the V-blocks. The stop blocks are equipped with V-grooves suitable for receiving the V-blocks. The positioning of the vehicle body is achieved by receiving the V-blocks into the corresponding V-grooves. For one-to-one positioning of the vehicle groove, the position of the V-blocks can be adjusted without much problem. However, for multiple V-blocks of the frame and multiple V-grooves of the lifting mechanism, it is difficult to achieve interchangeability due to over-positioning. Furthermore, when the lateral offset of the vehicle body is large, the sliding friction between the V-blocks and the V-grooves is large and sometimes they cannot slide in to form a fit.

[0059] In this application, the support part includes a support plate 41 and a support block 42. The support plate 41 cooperates with one set of third rollers 22, and the support block 42 cooperates with another set of third rollers 22. The top of the support block 42 is provided with a receiving groove suitable for accommodating the third rollers 22.

[0060] Therefore, the above settings can avoid over-positioning problems, thus achieving interchangeability. In addition, the third roller 22 will not have the problem of not being able to move into place due to large sliding friction, ensuring the stability of the cooperation between the lifting mechanism 40 and the vehicle body.

[0061] According to some embodiments of the present invention, a movable permanent magnet 50 is provided on the vehicle body, the frame 20 and / or the suspension assembly 30. The permanent magnet 50 is adapted to magnetically engage with a permanent magnet plate to improve the guiding force of the vehicle body. The permanent magnet 50 can be selectively moved along the height direction of the vehicle body.

[0062] In existing technologies, the centrifugal force is too large during each small-radius turn of a high-temperature superconducting magnetic levitation vehicle, which may cause the vehicle to move outward and not return. After multiple accumulations, the vehicle deviates too much from the center and the levitation force decreases.

[0063] In some embodiments, one or more of the vehicle body, frame 20 and / or suspension assembly 30 of this application are provided with permanent magnets 50, which are adapted to magnetically engage with permanent magnet plates on the track 10, thereby improving the guiding force of the vehicle body.

[0064] Specifically, a permanent magnet 50 is added to the vehicle body to attract the permanent magnet plate of the track 10. When the vehicle body deviates from the center of the track 10, a lateral force will pull the vehicle body back to the center of the track 10, thereby achieving passive guidance of the vehicle body and ensuring that the vehicle body will not deviate from the track due to centrifugal force when turning. Although some levitation force will be sacrificed, it can ensure that the guiding force is sufficient when turning. The loss of levitation force can be easily solved by appropriately increasing redundancy. The cost of increasing redundancy is too high for insufficient guiding force, and the cumulative offset caused by magnetic flux creep still cannot be solved.

[0065] Insufficient guiding force significantly limits the application of high-temperature superconducting magnetic levitation. (See also:) Figure 7 This application, by adding a guide magnet, achieves a guide force gain of 1000N when the vehicle body deviates by 5mm, at the cost of a nearly 5000N loss of levitation force. For high-temperature superconducting magnetic levitation, the guide force required for cornering is far less than the vehicle's own weight. Therefore, this application can ensure sufficient centripetal force by sacrificing only a small amount of levitation force, greatly expanding the application range of high-temperature superconducting magnetic levitation.

[0066] Thus, through magnetic guidance (the attraction between the permanent magnet 50 and the permanent magnet plate of the track 10), the vehicle body can stably return to the center of the track 10 even after multiple small-radius turns, greatly increasing the adaptability of the vehicle body to the track 10 and reducing the turning radius requirement of the track 10.

[0067] It is worth mentioning that the permanent magnet 50 is movably connected to the vehicle body, the frame 20 and / or the suspension assembly 30. The permanent magnet 50 can be moved manually along the height direction of the vehicle body, thereby adjusting the distance between the permanent magnet 50 and the track 10.

[0068] Preferably, the permanent magnet 50 is movably connected to the vehicle body, frame 20, and / or suspension assembly 30 via a driving component. The driving component has a driving part that moves along the height direction of the vehicle body. The driving part is connected to the permanent magnet 50. When the driving component operates, it causes the driving part to move along the height direction of the vehicle body, thereby realizing the movement of the permanent magnet 50. Thus, the above arrangement allows the permanent magnet 50 to automatically adjust the distance between itself and the track 10. It is worth mentioning that the driving component can be a drive motor, etc., and is not limited here.

[0069] In existing technologies, the vehicle body shifts outward under centrifugal force when cornering. Due to the characteristics of high-temperature superconducting magnetic levitation, the vehicle body cannot completely return to its original track center when leaving the corner. After multiple cornerings, the accumulated offset distance causes the vehicle body center to deviate too much from the track center, thus affecting the levitation force and guiding force of the superconducting levitation. The traditional method is to add superelevation to the corner, making the outer track higher than the inner track. This way, when the vehicle body tilts in the corner, the component of gravity can counteract the centrifugal force, preventing the vehicle body from shifting outward in the corner. However, the superelevation method brings many difficulties to the track manufacturing.

[0070] In this application, the track 10 includes an outer rail and an inner rail, with at least a portion of the outer rail's top surface being higher than the inner rail's top surface. Therefore, this arrangement allows for raising the outer rail by a certain height in a portion or all of the track 10, ensuring the vehicle body remains in an inclined state (outer side higher than inner side) on this portion of the track 10. The vehicle body will move inward under the influence of gravity. Since the vehicle's speed and trajectory are essentially fixed, the impact of curves on the vehicle's lateral displacement can be predicted. This allows for the calculation of the increased height and length of the outer rail compared to the inner rail. The inclination of the track 10, causing the vehicle body to move inward, counteracts the effect of curves on the vehicle's outward displacement.

[0071] In other embodiments, since the vehicle body will move outward under the action of centrifugal force when going through a curve, this application can also counteract the effect of the curve on the outward movement of the vehicle body by controlling the difference in the cooling height of the inner and outer rail fields.

[0072] Specifically, in actual operation, by making the field cooling height of the outer rail higher than that of the inner rail (the field cooling height refers to the height of the cryogenic levitation device when liquid nitrogen is added for cooling), after cooling and levitation, the outer side of the car body will be higher than the inner side, so that the car body is always in an inward tilting state. This can also achieve the effect of raising the outer rail. The levitation tilt of the car body can be adjusted by controlling the field cooling height, thereby reducing the difficulty of processing the track 10.
