Description

Technical Field

[0001] The present invention relates to the field of rail transportation technology, and in particular to a wheel-rail-permanent magnet electric fusion magnetic levitation rail transportation system. Background Art

[0002] With the deepening implementation of my country's strategy to build a strong transportation nation and the continuous upgrading of its railway network, earlier lines built with lower technical standards are gradually being replaced by high-standard lines. 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. Notably, magnetic levitation transportation technology, which combines high speed, quiet operation, and strong gradeability, has become a research hotspot in the rail transit sector. To efficiently activate idle resources and improve overall efficiency, the wheel-rail-magnetic levitation fusion system has attracted attention due to its economical and innovative approach. This fusion solution adheres to the principle of "minimizing transformation and maximizing 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 manageable costs, is the optimal fit for existing wheel-rail systems. This allows the construction of a permanent magnet electric levitation-wheel-rail hybrid system, providing an intensive technical approach for the renovation of existing railways.

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

[0004] The present invention aims to provide a wheel-rail-permanent magnet electric hybrid maglev rail transit system to improve the above-mentioned problems. To achieve the above-mentioned objectives, the present invention adopts the following technical solutions:

[0005] The present application provides a wheel-rail-permanent magnet electric fusion magnetic levitation rail transit system, characterized by comprising:

[0006] sleeper, wherein the sleeper is at least one, and the sleeper is arranged in parallel along the direction of travel, and a guide rail is provided on the sleeper.

[0007] a vehicle frame, the vehicle frame moving along the guide rails,

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

[0009] A stator, the stator being arranged on the guide rail and located on the side of the guide rail,

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

[0011] The beneficial effects of the present invention are:

[0012] The present invention provides a stable foundation for the entire system by arranging sleepers in parallel along the direction of travel. Guide rails are mounted on the sleepers, along which the vehicle frame moves. Guide wheels are mounted at the bottom of the frame and contact the rails, guiding the vehicle frame forward or backward in a predetermined direction through contact with the rails. The stator is mounted on the side of the rails, and the mover is mounted on the frame and parallel to the stator axis. When the stator is energized, an alternating magnetic field is generated. This magnetic field acts on the mover, which is then subjected to electromagnetic force, thereby propelling the vehicle frame along the rails, enabling the operation of the rail transit system.

[0013] By placing the stator on the side of the guide rail, the present invention allows the guide rail to be reused, using the guide rail as the motor stator backplane, thereby increasing the motor's thrust. The stator is placed on the side of the guide rail to form a spatially offset layout with the onboard wheelset. When the stator moves with the wheel, it interacts with the traveling wave magnetic field excited by the stator windings within the rail, generating radial electromagnetic guidance thrust while driving the train longitudinally, achieving the integrated integration of drive and guidance functions. This design significantly improves the dynamic stability of the suspension guidance through the spatial coordination of the electromagnetic thrust field and the mechanical wheel-rail system, reducing the risk of mechanical wear at the wheel-rail interface while ensuring the train's operational reliability and curve adaptability under high-speed conditions.

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

[0022] Sleeper 1, there is at least one sleeper 1, at least one sleeper 1 is arranged in parallel along the travel direction, and a guide rail 2 is provided on the sleeper 1,

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

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

[0025] The stator 5 is provided on the guide rail 2 and is located on the side of the guide rail 2.

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

[0027] In this embodiment, the sleepers 1 are arranged parallel to the direction of travel, providing a stable foundation 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. Through contact with the guide rails 2, the vehicle frame 3 is guided forward or backward in a predetermined direction. The stator 5 is mounted on the side of the guide rail 2, and the mover 6 is mounted on the vehicle frame 3 and parallel to the axis of the stator 5. When the stator 5 is energized, an alternating magnetic field is generated. Under the action of this magnetic field, the mover 6 is subjected to an electromagnetic force, thereby pushing the vehicle frame 3 along the guide rail 2, thereby realizing the operation of the rail transit system.

[0028] By placing the stator 5 on the side of the guide rail 2, the present invention allows the guide rail 2 to be reused. The stator 5 is spatially offset from the onboard wheelset. When the mover 6 moves with the wheels, it interacts with the traveling magnetic field excited by the stator 5 windings within the rail, generating radial electromagnetic guidance thrust while driving the train longitudinally, thus integrating drive and guidance functions. This design significantly improves the dynamic stability of the suspension guidance through the spatial coordination of the electromagnetic thrust field and the mechanical wheel-rail system, reducing the risk of mechanical wear at the wheel-rail interface while ensuring the train's operational reliability and curve adaptability under high-speed conditions.

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

[0030] In this embodiment, the two stators 5 are respectively arranged on adjacent sides of the two guide rails 2. When energized, the magnetic fields generated by them interact with each other and jointly generate an electromagnetic driving force with the movers 6 located on both sides of the connecting frame 7. The connecting frame 7 is arranged on the frame 3 to fix the two movers 6 in appropriate positions so that the movers 6 can effectively interact with the magnetic field of the stator 5. A plurality of guide wheels 4 are also provided to ensure the stability and guidance 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 the frame 3 with a stable and powerful driving force and guiding force, ensuring the smooth operation of the system.

[0031] Furthermore, the connecting frame 7 is slidably provided on the vehicle 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 vehicle frame 3. When the train reaches a curve, the stator 5 is mounted on the guide rail 2. The guide rail 2 is curved at the curve, so the stator 5 and the mover 6 have different coverage areas at the inner and outer rails. The connecting frame 7 is slidable and adjustable, and can slide between the two stators 5, thereby driving the mover 6 to move to the appropriate 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 the electromagnetic force and ensuring that the system maintains efficient operation under different operating conditions. When the train turns, the sliding of the connecting frame 7 allows the mover 6 to better adapt to the changes in the magnetic field of the stator 5, providing sufficient centripetal force to ensure a smooth turn.

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

[0034] In this embodiment, permanent magnets, acting as movers 6, are positioned on the sides of the guide rails 2. When the stator 5 is energized to generate an alternating magnetic field, the permanent magnets are subjected to an electromagnetic force. Because the permanent magnets themselves have a stable magnetic field, they interact with the magnetic field of the stator 5 to generate the driving force that propels the frame 3 along the guide rails 2. The permanent magnets do not require additional power for excitation; as long as the stator 5 magnetic field persists, they continuously generate electromagnetic force, ensuring stable system operation.

[0035] Furthermore, the stator 5 is a stator coil evenly distributed on the side of the guide rail 2, and the stator 5 is connected to the guide rail 2 by snap-fitting.

[0036] In this embodiment, the stator 5 coils are evenly distributed along the sides 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 generate electromagnetic force. The snap-fit ​​connection allows the stator 5 coils to be securely fixed to the guide rail 2 while being easily removable for maintenance or replacement. The evenly distributed stator 5 coils ensure uniform electromagnetic force along the length of the guide rail 2, providing a stable driving force for the frame 3 and enabling smooth operation of the train.

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

[0038] In this embodiment, conductor plates 8 are positioned on both sides of the sleeper 1, parallel to the guide rail 2. A permanent magnet array 9 is positioned on the vehicle frame 3, parallel to the conductor plates 8. The magnetic field generated by the permanent magnet array 9 interacts with the conductor plates 8, generating an electromagnetic force. This electromagnetic force provides levitation, allowing the train to decouple from the guide rail 2 to a certain extent, reducing friction and improving operational efficiency. It also provides guidance, ensuring the train follows the predetermined track direction and enhancing operational stability. During train operation, the electromagnetic interaction between the permanent magnet array 9 and the conductor plates 8 persists, ensuring stable levitation and guidance performance.

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

[0040] In this embodiment, at least two permanent magnet arrays 9 are located on either side of the frame 3 and interact with the conductor plates 8 on either side of the sleeper 1. During train operation, the permanent magnet arrays 9 on either side generate electromagnetic forces of varying strengths and directions with the conductor plates 8, depending on road conditions and train status. For example, when the train turns, the outer permanent magnet arrays 9 generate a stronger guiding force, guiding the train through the turn smoothly. When the train accelerates or decelerates, the two permanent magnet arrays 9 coordinately adjust the suspension force to ensure smooth operation. This coordinated operation of the two permanent magnet arrays 9 provides the train with more stable and flexible suspension and guidance performance.

[0041] Furthermore, the guide wheel 4 has a blocking portion 401 , and the blocking portion 401 is located on the inner side of two adjacent guide wheels 4 . The blocking portion 401 is used to prevent the guide wheel 4 from separating from the guide rail 2 in the horizontal direction.

[0042] In this embodiment, when the train is affected by external factors and the guide wheels 4 tend to horizontally deviate from the guide rails 2, the blocking portions 401 on the inner sides of the adjacent guide wheels 4 prevent further movement of the guide wheels 4. The blocking portions 401 closely cooperate with the guide wheels 4, physically confining them within the confines of the guide rails 2. This allows the guide wheels 4 to maintain contact with and run along the guide rails 2, thereby maintaining the stability of the train's travel direction and preventing derailment.

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

[0044] In this embodiment, the car body 10 is mounted on the frame 3 in a horizontally sliding manner via guide grooves 301. The guide grooves 301 provide guidance for the sliding of the car body 10, keeping its sliding direction parallel to the direction of travel. When the train formation needs to be adjusted, the car body 10 can slide along the guide grooves 301, conveniently adding or removing car bodies 10. During train operation, the guide grooves 301 ensure that the car body 10 moves with the frame 3 and limit its horizontal displacement, ensuring a stable relative position between the car body 10 and the frame 3 and enabling smooth train operation.

[0045] Furthermore, it includes at least one linear telescopic assembly 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 assemblies 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, the linear telescopic assembly 11 is hinged at one end to the car body 10 and at the other end to the adjustment frame. An even number of linear telescopic assemblies 11 are evenly distributed on both sides of the adjustment frame 7 along the conveying direction of the car body 10. As the train is running, the linear telescopic assemblies 11 automatically adjust their length based on the train's operating state. For example, when the train turns, the outer linear telescopic assemblies 11 extend while the inner linear telescopic assemblies 11 contract, allowing the car body 10 to adjust to the curvature of the curve and maintain good contact with the track. When the train is navigating uphill or downhill, the linear telescopic assemblies 11 adjust the tilt angle of the car body 10 to maintain a level ride, ensuring passenger comfort. The coordinated operation of the linear telescopic assemblies 11 improves the train's stability and safety under various operating conditions.
