Description

Technical Field

[0001] The utility model belongs to the technical field of wheels, and particularly relates to a maglev electric wheel and a maglev vehicle. Background Art

[0002] With the development of technology in the era, when people travel by vehicle, their requirements for the vehicle are getting higher and higher. For example, they hope that the vehicle is more stable during operation and does not produce bumps; the structure of the vehicle is more in line with the ergonomic design to increase the comfort during driving, and the vehicle can start quickly and adjust the speed quickly, etc. Generally, an automobile is composed of components and structures such as a body, an engine, a chassis, wheels, and an electrical system. Among them, the wheels play the role of bearing the entire weight of the vehicle, receiving the drive of the drive system, and driving the vehicle to travel. The wheel also includes structures such as a tire, a rim, and a spoke. In recent years, in order to meet the requirements of people for the smooth operation of the vehicle, more and more companies and enterprises are researching and developing maglev electric wheels. Using the maglev principle, the components on the tire do not contact, and through this gap structure, the friction between the wheel and other components can be reduced, thereby reducing wear. At the same time, the wheel adopting the maglev structure can also automatically adjust the gap between the components generating maglev of the wheel when encountering bumps, thereby reducing such bumps and making the vehicle more stable during operation.

[0003] An existing maglev wheel with the patent number CN110406313A includes a rotating body that can rotate around a fixed body outside the fixed body. A plurality of magnets are arranged on the outside of the fixed body, and the plurality of magnets form at least two annular magnet arrays. The rotating body includes a tire and an annular magnet arranged inside the tire that can cooperate with the annular magnet array. Through the cooperation of the annular magnet and the annular magnet array, the fixed body and the rotating body can rotate without friction, reducing friction resistance and energy consumption. Although this device is provided with a maglev structure to reduce the friction between the fixed body and the rotating body, the wheel body is not provided with a driving device and cannot realize the independent drive of a single wheel body. Moreover, a protection structure for preventing collision between the fixed body and the rotating body is not provided, and the fixed body and the rotating body are prone to collision in some cases, which may destroy the suspension balance between the fixed body and the rotating body, reducing the stability and safety of the maglev wheel.

[0004] Therefore, the main task of the present utility model is to design a maglev wheel with more stable and safe operation. Summary of the Utility Model

[0005] The present utility model discloses a maglev electric wheel and a maglev vehicle, aiming to solve the technical problems of insufficient operation stability and safety of the maglev electric wheel in the above-mentioned existing technology.

[0006] To solve the above existing technical problems, the technical solutions adopted by the present utility model are as follows:

[0007] A magnetic levitation electric wheel, comprising a connection system and a tire assembly rotatable about the connection system;

[0008] The tire assembly includes a rim, and a magnetic levitation system for levitating the connection system relative to the tire assembly is provided on the rim and / or the connection system;

[0009] A drive system for rotating the tire assembly about the connection system is provided on the rim and / or the connection system;

[0010] A support and protection system for maintaining the distance between the rim and the connection system is further provided between the rim and the connection system.

[0011] After adopting this technical solution, the connection system and the tire assembly rotatable about the connection system can first levitate the connection system relative to the tire assembly through the magnetic levitation system provided on the rim and / or the connection system, and then drive the tire assembly to rotate relative to the connection system through the drive system provided on the rim and / or the connection system. At this time, the tire assembly rotates in a non-contact levitation manner relative to the connection system. When the magnetic levitation electric wheel is connected to a vehicle body or the like, the magnetic levitation electric wheel will drive the vehicle body to move, thereby driving the vehicle equipped with the magnetic levitation electric wheel to run. Compared with traditional hub-type tires during operation, this non-contact magnetic levitation electric wheel can reduce friction and energy consumption by generating levitation between components, and can be independently driven and controlled through the drive system provided on the wheel body, making the magnetic levitation electric wheel more stable, flexible in operation, and precise in control during operation.

[0012] Meanwhile, a support and protection system is also provided between the rim and the connection system to maintain the distance between the rim and the connection system. Through the support and protection system, the distance between the rim and the connection system can be adjusted in extreme cases, so that the distance between the rim and the connection system is maintained within a certain range, thereby preventing the rim and the connection system from colliding, and increasing the stability and safety of the device during operation.

[0013] Wherein, the magnetic levitation system includes a first levitation assembly provided on the rim, and a second levitation assembly cooperating with the first levitation assembly is provided on the connection system, and the support and protection system is used to prevent the first levitation assembly and the second levitation assembly from colliding.

[0014] After adopting this technical solution, through the interaction between the first levitation assembly on the rim and the second levitation assembly on the connection system, the connection system can be levitated relative to the rim, which is convenient for the rim to rotate relative to the connection system in a non-contact manner through the drive system later, reducing the friction and energy consumption between the tire assembly and the connection system, and achieving the purpose of making the device operate stably and energy-efficiently.

[0015] In the initial stage of the maglev system startup, the suspension distance can be passively adjusted through the support and protection system, so as to obtain an initial gap between the first suspension component and the second suspension component; when the operation of the maglev electric wheel tends to be stable, the suspension distance is automatically adjusted through the maglev system between the first suspension component and the second suspension component. In addition, the support and protection system can effectively prevent collisions between the first suspension component and the second suspension component under extreme conditions, and the extreme conditions include excessive road surface bumps, major collisions of the wheel body, or malfunctions of the maglev system, etc.; therefore, the setting of the support and protection system not only ensures the operation stability and safety of the maglev electric wheel, but also has the function of leaving space and time for automatic adjustment of the suspension distance, making the device have a better fault tolerance range.

[0016] Among them, the first suspension component and the second suspension component cooperate to form one of a high-temperature superconducting magnetic system, an electromagnetic system, and a permanent magnetic system.

[0017] After adopting this technical solution, the first suspension component and the second suspension component can select different suspension materials and suspension principles according to actual needs, so as to select different maglev systems, making the device have multiple choices and thus making the device more practical.

[0018] Among them, the drive system includes a linear motor primary or a linear motor secondary arranged on the inner side of the wheel rim, and a linear motor secondary or a linear motor primary is arranged on the connection system to cooperate with it.

[0019] After adopting this technical solution, through the cooperation of the linear motor primary or linear motor secondary and the linear motor secondary or linear motor primary on the wheel rim and the connection system, the wheel rim can be driven to rotate relative to the connection system, enabling the device to operate. By directly arranging the linear motor primary or linear motor secondary on the wheel rim or the connection system, the power source is directly connected to the moving bearing component, reducing the transmission of the power source in the power line direction, thereby reducing energy consumption, enabling the device to have greater kinetic energy during operation, and the wheel body is independently controlled, with more flexible operation and more precise control.

[0020] Among them, the second suspension component is a high-temperature superconducting magnet, and the first suspension component is a first permanent magnet.

[0021] After adopting this technical solution, when the first suspension component is a first permanent magnet, the first permanent magnet is the first part of the permanent magnet, and the permanent magnet further includes a second permanent magnet, and the second permanent magnet serves as the primary or secondary of the linear motor, thus making the overall structure more concise. The cooperation of the high-temperature superconducting magnet and the permanent magnet can enable the wheel rim and the connection system respectively connected to the first suspension component and the second suspension component to have better suspension performance.

[0022] Among them, the support and protection system includes an adjustment rod, one end of the adjustment rod is in contact with or connected to the rim, and the other end is in contact with or connected to the connection system.

[0023] After adopting this technical solution, when an accident or other situation occurs and there is a tendency for the first suspension assembly and the second suspension assembly to collide, the setting of the adjustment rod can always adjust the distance between the rim and the connection system. The second suspension assembly is connected to the connection system. In this case, the adjustment rod can adjust the distance between the first suspension assembly and the second suspension assembly to prevent the first suspension assembly and the second suspension assembly from colliding. Therefore, the setting of the support and protection system increases the stability of the first suspension assembly and the second suspension assembly during operation, and further increases the stability and safety of the device during operation. Because the collision between the second suspension assembly and the second suspension assembly is reduced, the service life of the first suspension assembly and the second suspension assembly can also be extended, and the cost of the device during use is reduced.

[0024] Among them, one end of the adjustment rod is fixedly connected to the connection system, and a support wheel is rotatably connected to the other end of the adjustment rod, and the support wheel is in contact with the inner side of the rim.

[0025] After adopting this technical solution, the setting of the support wheel can provide buffering when the adjustment rod is in contact with the rim. When an accident occurs, in order to prevent the first suspension assembly and the second suspension assembly from colliding, the pressure when the end with the support wheel is in contact with the rim is reduced, thereby reducing the damage caused by the adjustment rod squeezing the rim, and improving the stability of the adjustment rod in adjusting the suspension distance; at the same time, the service life of the components of the device is improved, and the device is effectively protected.

[0026] Among them, the tire assembly further includes a tire provided on the outer side wall of the rim, and the tire can be an inflatable tire or a solid tire.

[0027] After adopting this technical solution, the tire can protect the rim and its internal components, and whether it is an inflatable tire or a solid tire, it can cooperate with the magnetic levitation system to provide buffering during the operation of the device, reduce the vibration of the device, etc., and make the device operate more smoothly.

[0028] Among them, a braking system is connected to the connection system and / or the rim.

[0029] After adopting this technical solution, the braking system can brake the relatively moving connection system and rim, improve the function of the device, and make the device more comprehensive.

[0030] A maglev vehicle includes the above-mentioned maglev electric wheel.

[0031] After adopting this technical solution, the maglev vehicle using this maglev electric wheel is not only more stable during vehicle operation, but also safer during operation through the support and protection system.

[0032] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0033] (1) By adopting a maglev system, a drive system, a support and protection system, etc., while the tire assembly in this device rotates, the connection system can float relative to the tire assembly and provide protection for this device, thereby improving the safety of this device during use.

[0034] (2) By adopting the mode of arranging both the maglev system and the drive system on the rim and the connection system, it can provide a greater driving force for this device on the premise of reducing the volume of this device, thereby achieving the effect of improving the driving efficiency.

[0035] (3) The materials and levitation principles of the first levitation component and the second levitation component can be selected according to actual use, increasing the applicability of this device. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The following will be combined with Figures 1-6 to make a detailed description of the present utility model.

[0048] Embodiment 1

[0049] A maglev electric wheel, as Figures 1 to 6 shown, includes a connection system 2 and a tire assembly 6 that can rotate around the connection system 2;

[0050] The tire assembly 6 includes a rim 601, and a maglev system for suspending the connection system 2 relative to the tire assembly 6 is provided on the rim 601 and / or the connection system 2;

[0051] A drive system for rotating the tire assembly 6 around the connection system 2 is provided on the rim 601 and / or the connection system 2;

[0052] A support and protection system 5 for maintaining the distance between the rim 601 and the connection system 2 is further provided between the rim 601 and the connection system 2.

[0053] In this embodiment, the connection system 2 can be connected to other components of a vehicle such as the vehicle body.

[0054] In this embodiment, the connection system 2 is threadedly connected to other components of a vehicle such as the vehicle body. However, in other embodiments, as long as the connection system 2 can be stably connected to other components of a vehicle such as the vehicle body, other connection methods will not be repeated here.

[0055] In this embodiment, the magnetic levitation system includes two parts that cooperate to generate magnetic force. The two parts are respectively disposed on the rim 601 and the connection system 2. Through the respective actions of the two parts of the magnetic levitation system, the connection system 2 can be levitated relative to the rim 601. In addition to the above-described setting method of the magnetic levitation system, in other embodiments, the magnetic levitation system can also be directly disposed on the rim 601 or the connection system 2, and the other side directly adopts a component that can generate magnetic force with the magnetic levitation system. For example, the rim 601 can be directly made of ferromagnetic material, and a magnetic levitation system that can cooperate with the ferromagnetic material is disposed on the connection system 2, so that the connection system 2 can be levitated relative to the rim 601. Of course, there are many other magnetic levitation systems in this embodiment that can achieve the levitation of the connection system 2 relative to the rim 601, which will not be described one by one here.

[0056] In this embodiment, the drive system also includes two parts that cooperate to generate drive. One part is disposed on the rim 601, and the other part is disposed on the connection system 2. Through the mutual cooperation of the two parts of the drive system, the tire assembly 6 can be rotated around the connection system 2. In other embodiments, the drive system can also be directly disposed on the rim 601 or the connection system 2 alone, and the other part directly adopts a component that can generate driving force with the drive system. For example, ferromagnetic material is used on the rim 601, and a drive system that can drive the ferromagnetic material to rotate is used on the connection system 2. As long as it can achieve the rotation of the rim 601 around the connection system 2, the drive system will not be described in detail here.

[0057] Connect the system 2 and the tire assembly 6 that can rotate around the connecting system 2. First, through the magnetic levitation system arranged on the rim 601 and the connecting system 2, the connecting system 2 can be levitated relative to the tire assembly 6. Then, the tire assembly 6 is driven to rotate relative to the connecting system 2 through the drive system arranged on the rim 601 and the connecting system 2. At this time, the tire assembly 6 rotates in a contactless levitation manner relative to the connecting system 2. When the magnetic levitation electric wheel is connected to the vehicle body, etc., the magnetic levitation electric wheel will drive the vehicle body to move, thereby driving the vehicle equipped with the magnetic levitation electric wheel to run. Compared with the traditional hub-type tire 602 during operation, this contactless magnetic levitation electric wheel can reduce friction and energy consumption by generating levitation between components. It is independently driven and controlled through the drive system arranged on the wheel body, making the magnetic levitation electric wheel more stable, flexible in operation, and precise in control during operation.

[0058] A support protection system 5 is also arranged between the rim 601 and the connecting system 2 to maintain the distance between the rim 601 and the connecting system 2. Through the support protection system 5, the distance between the rim 601 and the connecting system 2 can be adjusted in extreme cases, so that the distance between the rim 601 and the connecting system 2 is maintained within a certain range, thereby preventing the rim 601 and the connecting system 2 from colliding and increasing the stability and safety of the device during operation.

[0059] In this embodiment, the magnetic levitation system includes a first levitation component arranged on the rim 601, and a second levitation component that cooperates with the first levitation component is arranged on the connecting system 2. The support protection system 5 is used to prevent the first levitation component and the second levitation component from colliding.

[0060] In this embodiment, the first levitation component and the second levitation component are respectively embedded in the rim 601 and the connecting system 2. Embedding makes the connection surface between the two connected components relatively flat, reduces the overall volume of the device, has a relatively simple operation method, and can improve the production efficiency of the magnetic levitation electric wheel. In other embodiments, the first levitation component and the second levitation component can also be connected to the rim 601 and the connecting system 2 in other ways, such as threaded connection, adhesion, etc., as long as the first levitation component and the second levitation component can be stably connected.

[0061] Through the interaction between the first levitation component on the rim 601 and the second levitation component on the connecting system 2, the connecting system 2 can be levitated relative to the rim 601, which is convenient for the rim 601 to rotate relative to the connecting system 2 in a contactless manner through the drive system later, reducing the friction and energy consumption between the tire assembly 6 and the connecting system 2, and achieving the purpose of making the device move stably and energy-saving.

[0062] In the initial stage of the maglev system startup, the suspension distance can be passively adjusted through the support protection system 5, so as to obtain an initial gap between the first suspension assembly and the second suspension assembly; when the maglev electric wheel operation tends to be stable, the suspension distance is automatically adjusted through the maglev system between the first suspension assembly and the second suspension assembly. In addition, the support protection system 5 can effectively avoid collisions between the first suspension assembly and the second suspension assembly in extreme cases, and the extreme cases include excessive road surface bumps, major collisions of the wheel body, or malfunctions of the maglev system, etc. Therefore, the setting of the support protection system 5 not only ensures the operation stability and safety of the maglev electric wheel, but also has the function of leaving space and time for automatic adjustment of the suspension distance, making the device have a better fault tolerance range.

[0063] In this embodiment, the first suspension assembly and the second suspension assembly cooperate to form one of a high-temperature superconducting magnetic system, an electromagnetic system, and a permanent magnetic system.

[0064] In this embodiment, the first suspension assembly and the second suspension assembly can select different suspension materials and suspension principles according to actual needs, so as to select different maglev systems, making the device have multiple choices and thus more practicality. For example, when the first suspension assembly uses a permanent magnet 7, the second suspension assembly can use a high-temperature superconducting magnet 9 or other materials that can be suspended with the permanent magnet 7; when the first suspension assembly uses an electromagnet, the second suspension assembly can also use a permanent magnet 7, etc. to cooperate with the first suspension assembly so that the second suspension assembly can be suspended relative to the first suspension assembly. In other embodiments, other methods can also be used to achieve the suspension of the first suspension assembly and the second suspension assembly, which will not be described one by one here.

[0065] In this embodiment, the second suspension assembly is a high-temperature superconducting magnet 9, and the first suspension assembly is a first permanent magnet 701.

[0066] In this embodiment, the high-temperature superconducting magnet 9 is arranged in the Dewar 3, and the Dewar 3 is connected to the connection system 2. Arranging the Dewar 3 can effectively protect the high-temperature superconducting magnet 9, and the connection system 2 is also provided with pipelines and storage containers for inputting cooling media such as liquid nitrogen into the Dewar 3, which can not only avoid the high-temperature superconducting magnet 9 from being scratched during use, but also cool the high-temperature superconducting magnet 9, ensuring the suspension performance of the device during use and achieving more stable suspension.

[0067] In this embodiment, the Dewar 3 is of a semi-circular structure and is arranged on the side of the connection system 2 close to the ground. The Dewar 3 is arranged in a semi-circular structure, which can lower the center of gravity of the device and make the device more stable during use.

[0068] In this embodiment, the suspension between the first suspension assembly and the second suspension assembly refers to the suspension between the inner side wall of the rim 601 and the outer side wall of the dewar 3 close to the rim 601.

[0069] In this embodiment, when the first suspension assembly uses the first permanent magnet 701, the permanent magnet 7 is divided into the first permanent magnet 701 and the second permanent magnet 702. A plurality of the permanent magnets 7 are provided, and a plurality of the first permanent magnets 701 and the second permanent magnets 702 are both embedded in the rim 601. Or in other embodiments, the permanent magnet 7 is bonded to the inner side wall of the rim 601.

[0070] In this embodiment, the drive system includes the linear motor primary 4 or the linear motor secondary disposed inside the rim 601, and the connecting system 2 is provided with the matching linear motor secondary or the linear motor primary 4.

[0071] In this embodiment, the first permanent magnet 701 and the high-temperature superconducting magnet 9 cooperate to form a superconducting magnetic levitation system, and the second permanent magnet 702 serves as the secondary of the linear motor and acts with the primary of the linear motor to drive the rim 601 to rotate around the connecting system 2.

[0072] In this embodiment, as Figure 5 shown, the linear motor primary 4 and the high-temperature superconducting magnet 9 are arranged side by side horizontally on the side of the dewar 3 close to the rim 601.

[0073] In this embodiment, the "horizontal direction" refers to the direction from the left side to the right side of the tire 602 in the orientation shown Figure 5 .

[0074] Through the cooperation of the linear motor secondary and the linear motor primary 4 on the rim 601 and the connecting system 2, as described above, the linear motor secondary at this time refers to the second permanent magnet 702 of the permanent magnet 7. The cooperation between the linear motor primary 4 and the second permanent magnet 702 can drive the rim 601 to rotate relative to the connecting system 2, so that the device operates. The second permanent magnet 702 and the linear motor primary 4 are directly arranged on the rim 601 and the connecting system 2, and the power source is directly connected to the moving bearing assembly, reducing the transmission of the power source in the power line direction, thereby reducing the energy consumption, enabling the device to have greater kinetic energy during operation, and the wheel body is independently controlled, with more flexible operation and more precise control.

[0075] In this embodiment, the support and protection system 5 includes an adjusting rod 501. One end of the adjusting rod 501 is in contact with or connected to the rim 601, and the other end is in contact with or connected to the connecting system 2.

[0076] In this embodiment, the adjusting rod 501 is made of stainless steel. The stainless steel material has a stable structure and is not easy to rust, which can effectively extend the service life of the adjusting rod 501.

[0077] In this embodiment, one end of the adjusting rod 501 is connected to the connection system 2, and the other end is in contact with the rim 601. In other embodiments, one end of the adjusting rod 501 may be in contact with the connection system 2, and the other end is in contact with the rim 601. It is equivalent to that both sides of the connection system 2 and the rim 601 close to each other are provided with grooves for accommodating both ends of the adjusting rod 501. In this way, the adjusting rod 501 can be directly clamped in the grooves and only in contact with the rim 601 and the connection system 2 without connection. In other embodiments, one end of the adjusting rod 501 may also be connected to the rim 601, and the other end is in contact with the connection system 2. As long as the length of the adjusting rod 501 matches the distance between the connection system 2 and the rim 601, when there is a tendency of collision between the first suspension assembly and the second suspension assembly, the adjusting rod 501 can adjust the distance between the first suspension assembly and the second suspension assembly.

[0078] One end of the adjusting rod 501 is connected to the connection system 2, and the other end is in contact with the rim 601. When an accident or other situation occurs and there is a tendency of collision between the first suspension assembly and the second suspension assembly, the setting of the adjusting rod 501 can always adjust the distance between the wheel body and the rim 601 and the connection system 2 in extreme cases. The second suspension assembly is connected to the connection system 2. In this case, the adjusting rod 501 can adjust the distance between the first suspension assembly and the second suspension assembly to prevent the first suspension assembly and the second suspension assembly from colliding. Therefore, the setting of the support protection system 5 increases the stability of the first suspension assembly and the second suspension assembly during operation. Furthermore, the setting of the support protection system 5 increases the stability and safety of the device during operation, reduces the collision between the second suspension assembly and the second suspension assembly, and can also extend the service life of the first suspension assembly and the second suspension assembly, reducing the cost of the device during use.

[0079] In this embodiment, one end of the adjusting rod 501 is fixedly connected to the connection system 2, and a support wheel 502 is rotatably connected to the other end of the adjusting rod 501, and the support wheel 502 is in contact with the inner side of the rim 601.

[0080] In this embodiment, a support wheel 502 is connected to one end of the adjusting rod 501 close to the rim 601. In other embodiments, support wheels 502 may be provided at both ends of the adjusting rod 501, or a support wheel 502 is provided at one end of the adjusting rod 501 close to the connection system 2, and no support wheel 502 is provided at the other end.

[0081] In this embodiment, the support wheel 502 and the adjusting rod 501 are threadedly connected.

[0082] In this embodiment, the support wheel 502 is made of hard rubber, which is wear-resistant and has micro-elasticity, and the buffering effect is better.

[0083] The provision of the support wheel 502 enables the adjusting rod 501 to provide buffering when it comes into contact with the rim 601. This reduces the pressure on the end with the support wheel 502 when it contacts the rim 601 to prevent the first suspension assembly and the second suspension assembly from colliding in the event of an accident, thereby reducing the damage caused by the extrusion of the adjusting rod 501 on the rim 601 and improving the stability of the adjusting rod 501 in adjusting the gap; at the same time, it extends the service life of the components of this device and effectively protects this device.

[0084] In this embodiment, the tire assembly 6 further includes a tire 602 provided on the outer sidewall of the rim 601.

[0085] In this embodiment, the tire 602 used in the tire assembly 6 is an inflatable tire. In other embodiments, the tire 602 can also be a solid tire.

[0086] The tire 602 can protect the rim 601 and its internal components, and both inflatable tires and solid tires can cooperate with the magnetic levitation system to provide buffering during the operation of this device, reducing vibrations of this device, etc., making the device operate more smoothly.

[0087] The specific usage method of this utility model is as follows:

[0088] Refer to Figures 1-2 , this device includes a tire assembly 6 and a connection system 2. The tire assembly 6 includes a rim 601 and a tire 602. The magnetic levitation system includes a first suspension assembly and a second suspension assembly respectively provided on the rim 601 and the connection system 2. The first suspension assembly is a first permanent magnet 701 embedded in the rim 601. The second suspension assembly includes a high-temperature superconducting magnet 9 provided in the dewar 3. The dewar 3 is connected to the connection system 2; the drive system includes a linear motor primary 4 arranged in parallel with the high-temperature superconducting magnet 9 in the dewar 3 and a linear motor secondary provided on the rim 601. The linear motor secondary is the second permanent magnet 702 provided on the rim 601. Both the high-temperature superconducting magnet 9 and the linear motor primary 4 are provided on the side of the dewar 3 close to the rim 601.

[0089] When the primary of the linear motor 4 is energized, the primary of the linear motor 4 drives the secondary of the linear motor, i.e., the second permanent magnet 702, to move through electromagnetic induction, thereby driving the rim 601 connected to the secondary of the linear motor to move. When the tire 602 connected to the rim 601 contacts a plane with friction, such as the ground, it can drive the tire 602 to move. At the same time, when the rim 601 moves relative to the connection system 2, the first permanent magnet 701 on the rim 601 and the high-temperature superconducting magnet 9 in the dewar 3 cooperate to make the connection system 2 levitate relative to the rim 601. In this way, a non-contact rotation of the rim 601 relative to the connection system 2 is achieved simultaneously. When the rim 601 rotates non-contact relative to the connection system 2, no matter what carrier, such as a vehicle body, is connected to this device, a smooth operation can be achieved.

[0090] When this device accidentally encounters a stone or other situations during operation, causing a tendency of the rim 601 to collide with the dewar 3, the overall length of the adjusting rod 501 and the supporting wheel 502 of the support protection system 5 always matches the length from the edge of the connection system 2 to the inner wall edge of the rim 601. Moreover, the adjusting rod 501 is connected to the connection system 2, and the end with the supporting wheel 502 contacts the rim 601. When there is a tendency for the rim 601 to collide with the dewar 3, the supporting wheel 502 abuts against the rim 601, making a slight adjustment to the gap between the dewar 3 and the rim 601, thereby preventing the dewar 3 from coming into contact with the rim 601 and enhancing the safety of this device during use.

[0091] When this device needs to brake, it can perform a gentle brake by changing the magnitude and direction of the current flowing through the primary of the linear motor 4.

[0092] Embodiment 2

[0093] This embodiment is basically the same as Embodiment 1, except that: in this embodiment, a braking system 8 is connected to the connection system 2 and / or the rim 601.

[0094] In this embodiment, the braking system 8 is provided on the connection system 2. In other embodiments, the braking system 8 can also be provided on the rim 601 or on both the connection system 2 and the rim 601.

[0095] In this embodiment, one side of the braking system 8 is connected to the connection system 2, and the other side contacts the rim 601.

[0096] In this embodiment, the braking system 8 adopts a telescopic structure, such as an electric telescopic rod, etc. When this device needs to brake, it can directly control the braking system 8 to extend, so that the end of the braking system 8 in contact with the rim 601 abuts, applying pressure to the rim 601 to stop the rim 601 from rotating.

[0097] In this embodiment, the braking system 8 is arranged on the side of the connection system 2 where the dewar 3 is not provided, and the extending direction of the braking system 8 is perpendicular to the rotation direction of the linear motor secondary, which can achieve the effect of rapid braking. The braking system 8 can brake the relatively moving connection system 2 and the rim 601, improving the function of the device and making the device more comprehensive.

In this embodiment, the connection system 2 can be connected to components of other vehicles such as the vehicle body.

[0102] In this embodiment, the connection system 2 is threadedly connected to components of other vehicles such as the vehicle body. However, in other embodiments, as long as the connection system 2 can be stably connected to components of other vehicles such as the vehicle body, other connection methods will not be repeated here.
