Description

Technical Field

[0001] This invention relates to the field of rail transit technology, and more specifically, to a wheel-rail-permanent magnet electric integrated maglev rail transit system. Background Technology

[0002] With the deepening implementation of my country's national strategy to build a strong transportation network and the continuous upgrading of the railway network, early-built lines with lower technical standards are gradually being replaced by high-standard railways. This has led to the idleness and abandonment of some existing lines, stations, and supporting facilities, resulting in resource waste and hindering the sustainable development of the industry. It is worth noting that maglev transportation technology, which combines high speed, quiet operation, and strong climbing ability, has become a research hotspot in the field of rail transit. To efficiently activate idle resources and improve overall efficiency, the wheel-rail-maglev integrated system has attracted much attention due to its combination of economy and innovation. This integrated solution follows the principle of "minimum modification and maximum compatibility." Through a systematic comparison of four technologies, including conventional electromagnetic levitation and high-temperature superconducting levitation, it was found that permanent magnet electric levitation technology, with its simple structure and controllable cost, can be optimally adapted to existing wheel-rail systems, constructing a permanent magnet electric levitation-wheel-rail composite system, providing an intensive technical path for the transformation of existing railways.

[0003] Therefore, we need to design a rail transit system to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a wheel-rail-permanent magnet electric integrated maglev rail transit system to improve the aforementioned problems. To achieve the above objective, the technical solution adopted by this invention is as follows:

[0005] This application provides a wheel-rail-permanent magnet electric integrated maglev rail transit system, characterized in that it includes:

[0006] The railway sleepers, at least one of which are arranged parallel to each other along the direction of travel, and each sleeper is provided with a guide rail.

[0007] The vehicle frame moves along the guide rail.

[0008] A guide wheel is disposed at the bottom of the frame and is used to contact the guide rail.

[0009] The stator is mounted on the guide rail and located on the side of the guide rail.

[0010] A mover is mounted on the frame and is parallel to the axis of the stator.

[0011] The beneficial effects of this invention are as follows:

[0012] This invention provides a stable foundation for the entire system by arranging sleepers parallel to the direction of travel. Guide rails are mounted on the sleepers, and the vehicle frame moves along these rails. Guide wheels are mounted on the bottom of the vehicle frame and contact the guide rails, guiding the vehicle frame forward or backward in a predetermined direction. The stator is located on the side of the guide rails, and the mover is mounted on the vehicle frame and parallel to the stator axis. When the stator is energized, it generates an alternating magnetic field. Under the influence of this magnetic field, the mover experiences an electromagnetic force, thereby propelling the vehicle frame along the guide rails, thus enabling the operation of the rail transit system.

[0013] This invention utilizes the stator positioned on the side of the guide rail, allowing for rail reuse. By using the guide rail as the stator backplate, the motor's thrust is enhanced. The stator's placement on the side of the guide rail creates a spatially offset arrangement with the vehicle's wheelsets. As the rotor moves with the wheels, it interacts with the traveling wave magnetic field generated by the stator windings within the rail, simultaneously driving the train longitudinally and generating radial electromagnetic guiding thrust, thus integrating driving and guiding functions. This design significantly improves the dynamic stability of the suspended guidance system through the spatial coordination of the electromagnetic thrust field and the mechanical wheel-rail system. This reduces the risk of mechanical wear on the wheel-rail contact surface while ensuring the train's operational reliability and curve adaptability at high speeds.

[0014] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing embodiments of the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the written description, claims, and drawings.

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.

[0021] like Figures 1-2 As shown, this embodiment provides a wheel-rail-permanent magnet electric integrated maglev rail transit system, characterized by comprising:

[0022] The track sleeper 1, at least one of which is arranged parallel to each other along the direction of travel, and a guide rail 2 is provided on the track sleeper 1.

[0023] The vehicle frame 3 moves along the guide rail 2.

[0024] Guide wheel 4 is disposed at the bottom of the frame 3 and is used to contact the guide rail 2.

[0025] Stator 5, the stator 5 is disposed on the guide rail 2, and the stator 5 is located on the side of the guide rail 2.

[0026] The mover 6 is mounted on the frame 3 and is parallel to the axis of the stator 5.

[0027] In this embodiment, the sleepers 1 are arranged parallel to each other along the direction of travel, providing a stable foundation support for the entire system. Guide rails 2 are mounted on the sleepers 1, and the vehicle frame 3 moves along the guide rails 2. Guide wheels 4 are mounted on the bottom of the vehicle frame 3 and contact the guide rails 2, guiding the vehicle frame 3 forward or backward in a predetermined direction through contact with the guide rails 2. A stator 5 is mounted on the side of the guide rails 2, and a mover 6 is mounted on the vehicle frame 3 and parallel to the axis of the stator 5. When the stator 5 is energized, it generates an alternating magnetic field. Under the influence of this magnetic field, the mover 6 experiences electromagnetic force, thereby propelling the vehicle frame 3 along the guide rails 2, thus enabling the operation of the rail transit system.

[0028] This invention reuses the guide rail 2 by placing the stator 5 on the side of the guide rail 2. The stator 5, positioned on the side of the guide rail 2, forms a spatially offset layout with the onboard wheelset. When the mover 6 moves with the wheels, it interacts with the traveling wave magnetic field excited by the windings of the stator 5 within the rail, generating radial electromagnetic guiding thrust while driving the train longitudinally, thus achieving integrated driving and guiding functions. This design significantly improves the dynamic stability of the suspended guidance through the spatial coordination of the electromagnetic thrust field and the mechanical wheel-rail system, reducing the risk of mechanical wear on the wheel-rail contact surface and ensuring the train's operational reliability and curve adaptability under high-speed conditions.

[0029] Furthermore, there are at least two of each of the guide wheels 4, the mover 6, and the stator 5, with the two stators 5 respectively disposed on the two guide rails 2 and located on adjacent sides of the two guide rails 2; it also includes a connecting frame 7, which is disposed on the frame 3, with the mover 6 disposed on the connecting frame 7 and the two movers 6 located on both sides of the connecting frame 7.

[0030] In this embodiment, two stators 5 are respectively disposed on adjacent sides of the two guide rails 2. When energized, the magnetic fields they generate interact with each other, jointly generating an electromagnetic driving force with the movers 6 located on both sides of the connecting frame 7. The connecting frame 7 is disposed on the frame 3, fixing the two movers 6 in appropriate positions, so that the movers 6 can effectively interact with the magnetic field of the stators 5. Multiple guide wheels 4 are also provided to ensure the stability and guiding accuracy of the frame 3 when running on the guide rails 2. The multiple guide wheels 4, movers 6 and stators 5 work together to provide a stable and powerful driving force and guiding force for the frame 3, ensuring the smooth operation of the system.

[0031] Furthermore, the connecting frame 7 is slidably disposed on the frame 3, and the connecting frame 7 is slidably located between the two stators 5.

[0032] In this embodiment, the connecting frame 7 is slidable on the frame 3. When the train reaches a curve, the stator 5 is mounted on the guide rail 2, which is curved at the curve. Therefore, the coverage areas of the stator 5 and the mover 6 at the inner and outer rails are different. The connecting frame 7 is slidable and adjustable, allowing it to slide between the two stators 5, thereby moving the mover 6 to a suitable position. This allows the relative position and distance between the mover 6 and the stator 5 to be adjusted according to actual operating conditions, optimizing the effect of electromagnetic force and ensuring efficient operation of the system under different working conditions. When the train turns, the sliding of the connecting frame 7 allows the mover 6 to better adapt to changes in the magnetic field of the stator 5, providing sufficient centripetal force to ensure smooth turning of the train.

[0033] Furthermore, the mover 6 is a permanent magnet, and the mover 6 is disposed on the side of the guide rail 2.

[0034] In this embodiment, the permanent magnet, acting as the mover 6, is disposed on the side of the guide rail 2. When the stator 5 is energized and generates an alternating magnetic field, the permanent magnet experiences an electromagnetic force under the influence of this magnetic field. Since the permanent magnet itself possesses a stable magnetic field, it interacts with the magnetic field of the stator 5, generating a driving force that propels the frame 3 along the guide rail 2. The permanent magnet does not require additional power for excitation; as long as the magnetic field of the stator 5 exists, it can continuously generate an electromagnetic force, ensuring the stable operation of the system.

[0035] Furthermore, the stator 5 is a stator 5 coil, which is evenly distributed on the side of the guide rail 2, and the stator 5 and the guide rail 2 are connected by a snap-fit ​​connection.

[0036] In this embodiment, the stator 5 coils are evenly distributed on the side of the guide rail 2 and connected to the guide rail 2 via a snap-fit ​​connection. When current is applied, the stator 5 coils generate an alternating magnetic field, which interacts with the mover 6 mounted on the frame 3 to produce an electromagnetic force. The snap-fit ​​connection method allows the stator 5 coils to be firmly fixed to the guide rail 2, while also allowing for easy disassembly when maintenance or replacement is required. The evenly distributed stator 5 coils ensure the uniformity of the electromagnetic force along the length of the guide rail 2, providing a stable driving force for the frame 3 and enabling the train to run smoothly.

[0037] Furthermore, it also includes a conductor plate 8 and a permanent magnet array 9. The conductor plate 8 is disposed on both sides of the sleeper 1 and is arranged parallel to the guide rail 2. The permanent magnet array 9 is disposed on the frame 3 and is arranged parallel to the conductor plate 8.

[0038] In this embodiment, conductor plates 8 are disposed on both sides of sleepers 1 and parallel to guide rails 2, while permanent magnet arrays 9 are disposed on the frame 3 and parallel to conductor plates 8. The magnetic field generated by the permanent magnet array 9 interacts with conductor plates 8, generating electromagnetic force. This electromagnetic force provides levitation force, allowing the train to detach from guide rails 2 to a certain extent, reducing friction and improving operating efficiency; it also provides guiding force, ensuring the train runs along the predetermined track direction and enhancing train stability. During train operation, the electromagnetic interaction between the permanent magnet array 9 and conductor plates 8 continues, ensuring stable levitation and guiding performance.

[0039] Furthermore, there are at least two permanent magnet arrays 9, which are distributed on both sides of the vehicle frame 3.

[0040] In this embodiment, at least two permanent magnet arrays 9 are distributed on both sides of the frame 3, and they interact with the conductor plates 8 on both sides of the sleepers 1. During train operation, the permanent magnet arrays 9 on both sides generate electromagnetic forces of different intensities and directions with the conductor plates 8 according to different road conditions and train status. For example, when the train turns, the outer permanent magnet array 9 generates a stronger guiding force to guide the train to turn smoothly; when the train accelerates or decelerates, the permanent magnet arrays 9 on both sides work together to adjust the levitation force to ensure the smooth operation of the train. Through the coordinated work of the permanent magnet arrays 9 on both sides, the train is provided with more stable and flexible levitation and guiding performance.

[0041] Furthermore, the guide wheel 4 has a blocking part 401, which is located inside two adjacent guide wheels 4. The blocking part 401 is used to prevent the guide wheel 4 from disengaging from the guide rail 2 in the horizontal direction.

[0042] In this embodiment, when the train is affected by external factors and the guide wheel 4 tends to detach from the guide rail 2 in the horizontal direction, the blocking part 401 on the inner side of the adjacent guide wheel 4 will prevent the guide wheel 4 from moving further. The blocking part 401 is in close cooperation with the guide wheel 4, and by physically blocking, it restricts the guide wheel 4 within the range of the guide rail 2, so that the guide wheel 4 can continue to contact the guide rail 2 and run along the guide rail 2, thereby ensuring the stability of the train's travel direction and preventing the train from derailing.

[0043] Furthermore, it also includes a vehicle body 10, which is slidably mounted on the frame 3 in a horizontal direction. The frame 3 has a guide groove 301, and the vehicle body 10 is slidably mounted in the guide groove 301. The sliding direction of the vehicle body 10 is parallel to the direction of travel in a horizontal direction.

[0044] In this embodiment, the car body 10 is slidably mounted on the frame 3 in the horizontal direction via a guide groove 301. The guide groove 301 provides guidance for the sliding of the car body 10, ensuring that its sliding direction is parallel to the direction of travel. When it is necessary to adjust the train formation, the car body 10 can slide along the guide groove 301, facilitating the addition or removal of the car body 10. During train operation, the guide groove 301 ensures that the car body 10 moves together with the frame 3 and restricts the horizontal displacement of the car body 10, ensuring the relative position of the car body 10 and the frame 3 remains stable, allowing the train to run smoothly.

[0045] Furthermore, it also includes at least one linear telescopic component 11, one end of which is hinged to the vehicle body 10 and the other end of which is hinged to the adjustment frame. There are an even number of linear telescopic components 11, which are evenly distributed on both sides of the adjustment frame along the conveying direction of the vehicle body 10.

[0046] In this embodiment, one end of the linear telescopic assembly 11 is hinged to the car body 10, and the other end is hinged to the adjusting frame. An even number of linear telescopic assemblies 11 are evenly distributed on both sides of the adjusting frame 7 along the conveying direction of the car body 10. When the train is running, the linear telescopic assemblies 11 can automatically adjust their length according to the train's operating status. For example, when the train turns, the outer linear telescopic assembly 11 extends, and the inner linear telescopic assembly 11 shortens, allowing the car body 10 to adjust according to the curvature of the curve and maintain good contact with the track. When the train is going uphill or downhill, the linear telescopic assembly 11 adjusts the tilt angle of the car body 10 to keep the car body 10 level and ensure passenger comfort. Through the coordinated work of the linear telescopic assemblies 11, the stability and safety of the train under different operating conditions are improved.
