Description

[0002] Magnetic levitation is a technology that uses magnetic force to overcome gravity and levitate objects.

[0003] Currently, maglev technology is used in the transportation sector, such as maglev trains. However, maglev trains can only run on fixed tracks and transport goods point-to-point, making them unsuitable for use on urban roads.

Detailed Implementation

[0048] The technical solutions of this application 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 this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. To make the technical solutions and advantages of this application clearer, they will be described in detail below with reference to the accompanying drawings.

[0049] Maglev cars offer agile driving capabilities, adapting to various urban scenarios. Typically, maglev vehicles utilize magnetic components like magnets attached to the wheels to provide a magnetic field. As the wheels rotate, they generate a time-varying magnetic field, which cuts through the induction lane, inducing a current and providing levitation force for the vehicle. However, initially, the wheels are in contact with the induction lane. Direct rotation due to friction would wear down the wheels and wouldn't generate sufficient levitation force. Therefore, maglev vehicles generally incorporate a lifting mechanism. Before levitation, the vehicle is "lifted" by this mechanism. Once the wheels are suspended, their rotation is controlled. When sufficient levitation force is provided, the lifting mechanism is retracted. This entire levitation process is complex and time-consuming, resulting in a slow levitation initiation speed.

[0050] In response, this application provides a magnetic levitation vehicle chassis, such as... Figure 1 As shown, the chassis of the magnetic levitation vehicle may include a frame 1, two first hubs 2, two second hubs 3, two first support members 4, and two second support members 5. The frame 1 includes a front axle 11 and a rear axle 12 spaced apart along the length of the vehicle. Two first support members 4 are spaced apart on the front axle 11, and two second support members 5 are spaced apart on the rear axle 12. Each first support member 4 has a first hub 2 on its inner side. The first hub 2 is rotatably connected to the front axle 11 and can generate a magnetic field when it rotates. Each second support member 5 has a second hub 3 on its inner side. The second hub 3 is rotatably connected to the rear axle 12 and can generate a magnetic field when it rotates. The outer diameter of the first hub 2 is smaller than the outer diameter of the first support member 4, and the outer diameter of the second hub 3 is smaller than the outer diameter of the second support member 5.

[0051] In the magnetic levitation vehicle chassis provided in this embodiment, a first hub 2 is provided on the front axle 11, and a second hub 3 is provided on the rear axle 12. Both the first hub 2 and the second hub 3 can generate magnetic fields when rotating. That is, during the rotation of the first hub 2 and the second hub 3, if an induction plate (such as a metal plate) is provided on or within the road surface, the time-varying magnetic field generated by the hub will cut the induction plate, thereby forming an induced current in the induction plate. According to the principle of electromagnetic induction and Lenz's law, the induced magnetic field generated by the induced current will generate an electromagnetic force with the original magnetic field, which will hinder this relative motion. Vertically, this manifests as a levitation force that suspends the vehicle, and longitudinally, it manifests as a driving force that propels the vehicle forward, thereby realizing the vehicle's levitation... Suspension and movement; and compared to related technologies, which require lifting the entire vehicle through a lifting mechanism and then controlling the rotation of the wheels to obtain levitation force, this application provides a first support member 4 on the outer side of the first wheel hub 2, the radial dimension of the first support member 4 being larger than that of the first wheel hub 2, and a second support member 5 on the outer side of the second wheel hub 3, the radial dimension of the second support member 5 being larger than that of the first wheel hub 2. That is, in the initial state, due to the provision of the first support member 4 and the second support member 5, the first wheel hub 2 and the second wheel hub 3 are already in a suspended state, and can rotate directly after receiving the levitation command from the host, without having to wait for the entire vehicle body to be suspended before rotating, resulting in a faster start-up speed.

[0052] Optionally, the difference between the outer diameter of the first support member 4 and the outer diameter of the first hub 2 is greater than or equal to 8 mm; and / or, the difference between the outer diameter of the second support member 5 and the outer diameter of the second hub 3 is greater than or equal to 8 mm.

[0053] Optionally, the induction plate can be a copper plate, an aluminum plate, or other metal plates with good conductivity. Those skilled in the art can select and adjust it according to actual needs.

[0054] In some embodiments of this application, such as Figure 2 As shown, the first hub 2 includes a first stator portion 21 and a first rotor portion 22 sleeved on the front axle 11. The first stator portion 21 is fixedly connected to the front axle 11, and the first rotor portion 22 is located outside the first stator portion 21 and is rotatable relative to the first stator portion 21; and / or, the second hub 3 includes a second stator portion 31 and a second rotor portion 32 sleeved on the rear axle 12. The second stator portion 31 is fixedly connected to the rear axle 12, and the second rotor portion 32 is located outside the second stator portion 31 and is rotatable relative to the second stator portion 31.

[0055] In the magnetic levitation vehicle chassis provided in this application embodiment, the first hub 2 includes a first stator 21 and a first rotor 22. When a levitation command is received, current is passed through the windings on the first stator 21, and the first stator 21 generates a magnetic field, which interacts with the first rotor 22 and drives the first rotor 22 to rotate. At this time, the first rotor 22 rotates relative to the first stator 21 and generates a time-varying magnetic field. The time-varying magnetic field interacts with the magnetic field generated at the induction plate, thereby realizing the levitation and movement of the vehicle. The principle of the second stator 31 is the same as that of the first stator 21, and will not be described in detail here.

[0056] It should be noted that the chassis of the magnetic levitation vehicle may also include a power supply device, which is electrically connected to the windings in the first stator section 21 and the second stator section 31, and supplies power to the first stator section 21 and the second stator section 31 after startup.

[0057] Alternatively, the power supply can be an on-board power supply.

[0058] In some embodiments of this application, such as Figure 2 As shown, the first rotor section 22 may include a first rotor disk 221 and a plurality of first magnets 222, the plurality of first magnets 222 being attached to the outer peripheral wall of the first rotor disk 221. The first hub 2 also includes a first rolling bearing 23, the first rolling bearing 23 being connected between the first rotor disk 221 and the first stator section 21; and / or, the second rotor section 32 includes a second rotor disk 321 and a plurality of second magnets 322, the plurality of second magnets 322 being attached to the outer peripheral wall of the second rotor disk 321. The second hub 3 also includes a second rolling bearing 33, the second rolling bearing 33 being connected between the second rotor disk 321 and the second stator section 31.

[0059] In the magnetic levitation vehicle chassis provided in this application embodiment, the first rotor disk 221 is rotatably connected to the first stator 21 through the first rolling bearing 23. When the winding on the first stator 21 is energized, a magnetic field is generated. This magnetic field interacts with the magnetic field generated by the multiple first magnets 222 attached to the first rotor disk 221, forcing the first rotor 22 to rotate. Then, the time-varying magnetic field generated by the multiple first magnets 222 cyclically cuts the induction plate. The time-varying magnetic field interacts with the magnetic field generated at the induction plate, thereby realizing the levitation and movement of the vehicle. The principle of the second rotor 32 is the same as that of the first rotor 22, and will not be described in detail here.

[0060] Optionally, the first magnet 222 can be a magnetic component such as a magnet steel or a neodymium iron boron permanent magnet; and / or, the second magnet 322 can be a magnetic component such as a magnet steel or a neodymium iron boron permanent magnet. Those skilled in the art can select and adjust the material and quantity of the first magnet 222 and / or the second magnet 322 according to actual needs.

[0061] In some embodiments of this application, each first support member 4 is rotatably connected to the front axle 11, and the first support member 4 can generate a magnetic field when it rotates; and / or, each second support member 5 is rotatably connected to the rear axle 12, and the second support member 5 can generate a magnetic field when it rotates, and the rotation direction of the second support member 5 is opposite to the rotation direction of the first support member 4.

[0062] When the maglev vehicle needs to levitate, the first hub 2 and the second hub 3 can be rotated to levitate the entire vehicle. To provide greater levitation force, making the vehicle more stable and faster, the first support member 4 and / or the second support member 5 in the chassis of the maglev vehicle provided in this embodiment can also rotate, generating a magnetic field during rotation. Once the maglev vehicle is levitated, the user can choose whether to activate the first support member 4 and / or the second support member 5 according to actual needs.

[0063] In addition, when a magnetic levitation vehicle in the relevant technology is in a suspended state, if it wants to turn to change its direction of travel, it needs to control the wheels to rotate at a different speed. However, the uniform rotation of the wheels is the key to providing stable levitation force. In other words, if the wheels rotate at a different speed while providing levitation force, it may cause the entire magnetic levitation vehicle to vibrate, and may even affect its levitation stability and steering accuracy.

[0064] In the magnetic levitation vehicle chassis provided in this application embodiment, a stable levitation force can be provided by the first hub 2 and the second hub 3. When steering is required, the first support member 4 and the second support member 5 on the outside can be controlled to rotate at a differential speed to achieve precise steering. Steering is achieved without affecting the levitation stability of the magnetic levitation vehicle.

[0065] Optionally, when the magnetic levitation vehicle is suspended in the air, a stable levitation force can be provided by the first support member 4 and the second support member 5, and the first wheel hub 2 and the second wheel hub 3 can be controlled to rotate at different speeds to achieve steering. Those skilled in the art can select and adjust according to actual needs.

[0066] In some embodiments of this application, such as Figure 3 As shown, the first support member 4 may include a third stator portion 41 and a third rotor portion 42 sleeved on the front axle 11. The third stator portion 41 is fixedly connected to the front axle 11, and the third rotor portion 42 is located outside the third stator portion 41 and is rotatable relative to the third stator portion 41; and / or, the second support member 5 includes a fourth stator portion 51 and a fourth rotor portion 52 sleeved on the rear axle 12. The fourth stator portion 51 is fixedly connected to the rear axle 12, and the fourth rotor portion 52 is located outside the fourth stator portion 51 and is rotatable relative to the fourth stator portion 51.

[0067] In the magnetic levitation vehicle chassis provided in this application embodiment, the first support member 4 includes a third stator 41 and a third rotor 42. When a levitation command is received, current is passed through the windings on the third stator 41, the third stator 41 generates a magnetic field, interacts with the third rotor 42, and drives the third rotor 42 to rotate. At this time, the third rotor 42 rotates relative to the third stator 41 and generates a time-varying magnetic field. The time-varying magnetic field interacts with the magnetic field generated at the induction plate, thereby realizing the levitation and movement of the vehicle. The principle of the fourth stator 51 is the same as that of the third stator 41, and will not be described in detail here.

[0068] Optionally, the third rotor section 42 may include a third rotor disk and a plurality of third magnets, the plurality of third magnets being attached to the outer peripheral wall of the third rotor disk, and the third hub further includes a third rolling bearing connected between the third rotor disk and the third stator section 41; and / or, the fourth rotor section 52 includes a fourth rotor disk and a plurality of fourth magnets, the plurality of fourth magnets being attached to the outer peripheral wall of the fourth rotor disk, and the third hub further includes a fourth rolling bearing connected between the fourth rotor disk and the fourth stator section 51.

[0069] In some embodiments of this application, such as Figure 1 As shown, the frame 1 may also include a main frame 13, two first connectors 14 and two second connectors 15; the first ends of the two first connectors 14 are rotatably connected to the main frame 13, and the second ends of the two first connectors 14 are axially connected to both ends of the front axle 11; the first ends of the two second connectors 15 are rotatably connected to the main frame 13, and the second ends of the two second connectors 15 are axially connected to both ends of the rear axle 12.

[0070] In the magnetic levitation vehicle chassis provided in this application embodiment, the front axle 11 is rotatably connected to the main frame 13 through two first connecting members 14, and the rear axle 12 is rotatably connected to the main frame 13 through two second connecting members 15. This can provide a certain buffer after the magnetic levitation vehicle chassis lands, and prevent the stress at the connection between the first support member 4 and the second support member 5 and the main frame 13 from being too great, which could lead to breakage.

[0071] Optionally, the first connector 14 is connected to the main frame 13 via a ball joint mechanism; and / or, the second connector 15 is connected to the main frame 13 via a ball joint mechanism.

[0072] To further enhance vibration damping capabilities, in some embodiments of this application, such as... Figure 1As shown, the frame 1 may further include two third connectors 16, with a corresponding third connector 16 disposed above each first connector 14. One end of the third connector 16 is connected to the main frame 13, and the other end is an open end, with a first gap between the open end and its corresponding first connector 14. The frame 1 also includes two fourth connectors 17, with a corresponding fourth connector 17 disposed above each second connector 15. One end of the fourth connector 17 is connected to the main frame 13, and the other end is an open end, with a second gap between the open end and its corresponding second connector 15. A first elastic damping member 18 is disposed in each first gap, and the first elastic damping member 18 is connected to the third connector 16 and its corresponding first connector 14, respectively. A second elastic damping member 19 is disposed in each second gap, and the second elastic damping member 19 is connected to the fourth connector 17 and its corresponding second connector 15, respectively. By setting the first elastic damper 18 and the second elastic damper 19, when the maglev vehicle lands, the connection end of the first connector 14 and the main frame 13 will move downward under the action of downward pressure, while the end of the first connector 14 near the front axle 11 will move upward. At this time, it will squeeze the first elastic damper 18. Under the action of the elastic restoring force of the first elastic damper 18, the entire chassis will produce a similar jumping situation. After squeezing the first elastic damper 18 multiple times, it can offset part of the downward pressure, thereby achieving the effect of shock absorption. The principle of the second elastic damper 19 is the same as that of the first elastic damper 18, and will not be described in detail here.

[0073] Optionally, the first elastic damping member 18 can be a spring; and / or, the second elastic damping member 19 can be a spring.

[0074] This application also provides a magnetic levitation vehicle, which includes the aforementioned magnetic levitation vehicle chassis.

[0075] In the magnetic levitation vehicle provided in this application embodiment, due to the adoption of the aforementioned magnetic levitation vehicle chassis, compared to the related technology which requires first lifting the entire vehicle through a lifting mechanism and then controlling the rotation of the wheels to obtain levitation force, this application provides a first support member 4 on the outer side of the first hub 2, the radial dimension of the first support member 4 being larger than that of the first hub 2, and a second support member 5 on the outer side of the second hub 3, the radial dimension of the second support member 5 being larger than that of the first hub 2. That is, in the initial state, due to the provision of the first support member 4 and the second support member 5, the first hub 2 and the second hub 3 are already in a suspended state, and can rotate directly after receiving the levitation command from the host, without having to wait for the entire vehicle body to be suspended before rotating, resulting in a faster start-up speed.

[0076] In some embodiments, such as Figure 4As shown, the magnetic levitation vehicle may also include a control unit 6, which is connected to the first hub 2 and the second hub 3 respectively, and controls the first hub 2 and the second hub 3 to rotate in opposite directions when a levitation command is received.

[0077] It should be noted that after the maglev vehicle starts, the first hub 2 and the second hub 3 rotate synchronously in opposite directions. Therefore, a backward force F1 can be generated at the first hub 2 and a forward force F2 can be generated at the second hub 3. Under the resultant force of F1 and F2, the maglev car can achieve levitation.

[0078] Optionally, the control unit 6 can control the rotation speed of the first hub 2 to be lower than the rotation speed of the second hub 3, so that F1 is less than F2. Then the magnetic levitation vehicle can achieve the purpose of moving forward under the action of F2. When braking is required, the rotation speed of the first hub 2 and the second hub 3 is adjusted so that the rotation speed of the first hub 2 is greater than the rotation speed of the second hub 3, so that F1 is greater than F2. Then the magnetic levitation vehicle can achieve the purpose of braking under the action of F1.

[0079] Optionally, the first support member 4 is rotatably connected to the front axle 11, and the second support member 5 is rotatably connected to the rear axle 12. Both the first support member 4 and the second support member 5 can generate a magnetic field when rotating. The control member 6 is also connected to the first support member 4 and the second support member 5 respectively, and when the magnetic levitation vehicle is levitated and a steering command is received, it controls the two first support members 4 to rotate differentially; and / or controls the two second support members 5 to rotate differentially.

[0080] When steering is required, stable levitation force can be provided through the first hub 2 and the second hub 3, and the first support member 4 and the second support member 5 on the outside can be controlled to rotate at different speeds to achieve precise steering. Steering can be achieved without affecting the levitation stability of the magnetic levitation vehicle.

[0081] For example, when a left turn is required, the rotational speed of the first support member 4 on the left is controlled to be greater than that of the first support member 4 on the right, and / or, the rotational speed of the second support member 5 on the left is controlled to be greater than that of the second support member 5 on the right. The same principle applies to right turns, which will not be elaborated further here.

[0082] In summary, the magnetic levitation vehicle provided in this application embodiment achieves stable levitation through the magnetic field force generated by the first hub 2 and the second hub 3 and the induction plate below the vehicle, resulting in a relatively fast start-up speed. While levitation, the vehicle can be steered by the differential rotation of the outer first support member 4 and the second support member 5, thus achieving levitation and aerial steering. Furthermore, this magnetic levitation vehicle is driven by electromagnetic force, producing no exhaust emissions, which helps reduce environmental pollution.
