[0002] With the rapid development of my country's tourism industry, tourist transportation has become an increasingly important means of effectively ensuring the flow of tourists between scenic spots and source areas, and its role in the tourism industry is becoming increasingly prominent. The convenience of tourist transportation is directly related to the audience level of a scenic spot.

[0003] Among them, medium- and low-speed maglev technology, as a new type of rail transit, leverages its unique suspension properties to provide visitors with a unique technological and visual impact. It is itself a mature transportation tool and tourism brand. Compared to subways and light rail, it offers advantages such as safety, comfort, vibration-free, low noise, pollution-free, and low construction and maintenance costs, meeting people's needs for high-quality commuting and travel. This means that the market prospects for maglev tourism rail are very promising and there is huge market demand.

[0004] In the existing technology, the structural form of the medium and low-speed maglev transportation system has been optimized, but its size and capacity still maintain the traditional rail transportation model, and a large number of existing medium and low-speed maglev subsystems are retained. There are problems such as unstable operation and poor line adaptability, resulting in poor market competitiveness and engineering promotion capabilities of the medium and low-speed maglev transportation system.

[0005] In summary, how to improve the operational stability and line adaptability of the maglev transportation system is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a semi-suspended maglev train transportation system, which can improve the operating stability and line adaptability of the maglev transportation system, and then improve the market competitiveness and engineering promotion capabilities of the medium and low-speed maglev transportation system.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] A semi-suspended maglev train transportation system comprises: a train system, a track system and a power supply system. The train system comprises two end cars and several middle cars arranged between the two end cars. The end cars all use rubber wheels to run on the track system, and the middle cars all use a suspended manner to run on the track system. The end cars and the middle cars, as well as the middle cars, are connected by couplers. The end cars are all connected to the power supply system to provide traction power for the middle cars. The track system is provided with a rack rail on a steep slope line, and the end cars are provided with a gear device that meshes with the rack rail and is used to provide traction power.

[0009] Preferably, the track system includes a track, a track beam for supporting the track, and a reaction rail for providing suspension force for the CRRC vehicle. The reaction rail is provided on the track beam, and the rubber wheel can run along the track.

[0010] Preferably, the end car includes an end car body, an end car bogie for supporting the end car body, a power device for driving the rubber wheel to rotate, and a guide device for constraining the running direction of the end car body. The end car body is arranged on the end car bogie, and the rubber wheel and the power device are provided under the end car bogie. The rubber wheel and the power supply system are both connected to the power device, and multiple groups of the guide devices are provided on both sides of the end car bogie.

[0011] Preferably, the power supply device of the power supply system is provided on the track beam, the end vehicle comprises an end vehicle collector shoe for contacting the power supply device to realize vehicle power supply, and the end vehicle collector shoe is connected to the power device;

[0012] Or the power supply device of the power supply system is a battery, the battery is arranged on the body of the end vehicle, and the battery is connected to the power device;

[0013] Or the power device is a fuel engine or an internal combustion engine.

[0014] Preferably, the CRRC includes a CRRC body, a CRRC bogie for supporting the CRRC body, a suspension module for cooperating with the reaction rail to produce a suspension effect, and a suspension controller.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] The core of the present invention is to provide a semi-suspended maglev train transportation system, which can improve the operating stability and line adaptability of the maglev transportation system, and then improve the market competitiveness and engineering promotion capabilities of the medium and low-speed maglev transportation system.

[0033] Please refer to Figures 1 to 8 .

[0034] This specific embodiment provides a semi-suspended magnetic levitation train transportation system, including: a train system, a track system and a power supply system. The train system includes two end cars 1 and several middle cars 2 arranged between the two end cars 1. The end cars 1 all use rubber wheels 3 to run on the track system, and the middle cars 2 all use a suspended manner to run on the track system. The end cars 1 and the middle cars 2, and the middle cars 2 and the middle cars 2 are all connected by couplers 4. The end cars 1 are all connected to the power supply system to provide traction power for the middle cars 2; the track system is provided with a rack rail 8 on the steep slope line, and the end cars 1 are provided with a gear device 15 that is meshed with the rack rail 8 and is used to provide traction power.

[0035] It's important to note that both end cars (1) are connected to the power supply system to provide traction to the middle car (2), while the middle car (2) is unpowered. This means the entire train system is pulled by the end cars (1), and the number of middle cars (2) can be determined based on specific circumstances. Therefore, even if one of the two end cars (1) fails, the remaining end car (1) can continue to pull the entire train, improving system stability.

[0036] It should also be noted that the semi-suspended maglev train transportation system provided by the present invention is suitable for scenic spots. It includes a train system, a track system, a power supply system, etc. It is a miniaturization and simplification of the existing maglev system. For example, the passenger capacity of the train system of this system does not need to be too large, so it can effectively reduce the vehicle load and structural complexity, making the system have stronger engineering applicability to meet the system requirements of different markets and environmental conditions. In addition, the car bodies of the end car 1 and the middle car 2 can be interconnected to form a fully connected train, and the car bodies of the end car 1 and the middle car 2 can also be independent of each other and not interconnected to form a non-connected train. The form of the train connection can be determined according to actual needs and actual conditions.

[0037] During actual use, the shape, structure, size, position, number, etc. of the train system, track system, power supply system, rack rail 8, gear device 15, end car 1 and middle car 2 can be determined according to actual conditions and actual needs.

[0038] When using the semi-suspended maglev train transportation system provided by the present invention, the end car 1 pulled by the rubber wheel 3 is connected to several unpowered suspended middle cars 2 and runs on the track system. It effectively combines the advantages of wheeled vehicles and maglev vehicles, and has the advantages of high line operation safety, low noise, small turning radius, good environmental performance, etc., and can make the entire train semi-suspended mode, that is, the end car 1 adopts wheel support and the middle car 2 adopts suspension mode. Among them, the wheeled vehicles at the end can effectively improve the stability of the train operation, and the suspended middle car 2 greatly improves the riding comfort of passengers. At the same time, because the power of the train comes from the head and tail end cars 1, even if one of the two end cars 1 fails, the other end car 1 can continue to pull the entire train to run, so as to improve the stability of the system operation. In addition, since the track system is provided with a rack rail 8 on the steep slope line, the end car 1 is provided with a gear device 15 that meshes with the rack rail 8. The gear device 15 can effectively improve the climbing ability of the end car 1 on the steep slope line, ensure the normal operation of the train, and effectively improve the line adaptability of the maglev transportation system.

[0039] In summary, the semi-suspended maglev train transportation system provided by the present invention can improve the operational stability and line adaptability of the maglev transportation system, thereby improving the market competitiveness and engineering promotion capabilities of the medium and low-speed maglev transportation system.

[0040] Based on the above embodiment, preferably, the track system includes a track 5, a track beam 6 for supporting the track 5, and a reaction rail 7 for providing suspension force for the CRRC 2. The reaction rail 7 is arranged on the track beam 6, and the rubber wheel 3 can run along the track 5.

[0041] It should be noted that the track beam 6, serving as the foundational support structure for the entire track system, can be constructed from either concrete or steel beams, depending on the project's specific application. The reaction rail 7 can be mounted on the track beam 6 via a fastening device. The reaction rail 7 interacts with the levitation electromagnets on the CRRC 2 to generate electromagnetic force, thereby providing levitation and guidance for the CRRC 2. For example, the reaction rail 7 can be mounted on the underside of the end wing of the track beam 6 using fasteners and related embedded components.

[0042] During actual use, the shape, structure, size, position, etc. of the track 5, track beam 6 and reaction rail 7 can be determined according to actual conditions and actual needs.

[0043] Preferably, the end car 1 includes an end car body 11, an end car bogie 12 for supporting the end car body 11, a power device 13 for driving the rubber wheel 3 to rotate, and a guide device 14 for constraining the running direction of the end car body 11. The end car body 11 is arranged on the end car bogie 12, and the rubber wheel 3 and the power device 13 are provided under the end car bogie 12. The rubber wheel 3 and the power supply system are both connected to the power device 13, and multiple sets of guide devices 14 are provided on both sides of the end car bogie 12.

[0044] It should be noted that the end car 1 mainly provides traction power for the train system, and the end car 1 relies on the rubber wheels 3 to run on the track 5. The end car 1 can be set as a driver's cab for use in train operation control. Among them, the main material of the end car body 11 can be set as aluminum alloy, which mainly includes main components such as the chassis, side walls, end walls and roof. Below the end car body 11 is the end car bogie 12, and the rubber wheels 3 are installed on the end car bogie 12. A power unit 13 is installed below the end car bogie 12. The power unit 13 can use a rotating motor or an internal combustion engine to drive the rubber wheels 3 to rotate through the axle and the reduction structure, thereby providing power for the train system. Moreover, multiple sets of guide devices 14 can be respectively set on the side of the end car bogie 12. The guide devices 14 are shaped to run on the side of the track beam 6 with the help of the rubber wheels 3. The guide devices 14 can effectively constrain the movement trajectory of the end car body 11 to ensure that the end car body 11 runs along the direction of the track 5.

[0045] Preferably, a rack rail 8 can be provided on the track beam 6, and a gear device 15 can be set on the end vehicle bogie 12. The gear device 15 is a gear power system parallel to the rubber wheel 3. The gear power system is engaged with the rack rail 8 in the direction of the running line, and is used to provide traction when the vehicle travels on a steep slope line.

[0046] Therefore, rack rails 8 only need to be installed on track 5 in special sections, such as sections with steep slopes. Gear units 15 are connected to the axles through a reduction mechanism and mesh with rack rails 8 on track 5 to provide traction for vehicles traveling on special lines. The traction force from the meshing gears can provide high torque, allowing vehicles to operate normally under special line conditions such as steep longitudinal slopes. This system combines the traction methods of rubber wheel 3 and rack rail 8. The end car 1 uses the rubber wheel 3 and gear unit 15 to jointly provide traction and braking force, greatly improving the train system's climbing performance and making the train system highly adaptable to different lines.

[0047] During actual use, the shape, structure, size, position, etc. of the end vehicle body 11, the end vehicle bogie 12, the power unit 13 and the guide device 14 can be determined according to actual conditions and actual needs.

[0048] Preferably, the power supply device 9 of the power supply system is arranged on the track beam 6, and the end vehicle 1 includes an end vehicle collector shoe 16 for contacting the power supply device 9 to realize vehicle power supply, and the end vehicle collector shoe 16 is connected to the power unit 13; or the power supply device 9 of the power supply system is a battery, and the battery is arranged on the end vehicle body 11, and the battery and the power unit 13 are connected; or the power unit 13 is a fuel engine or an internal combustion engine. Among them, setting the power unit 13 as a fuel engine or an internal combustion engine means that the power source of the end vehicle 1 is a fuel power unit, and there is no need to add an additional power supply device 9.

[0049] In this embodiment, the power source for the terminal car 1 can be a third contact rail, a battery, or a fuel-powered power unit. Braking of the terminal car 1 primarily relies on the disc brakes on the rubber wheels 3 and the gear rack 8. The gear rack 8 is primarily used in special track sections (e.g., sections with steep gradients).

[0050] When the power supply system uses a third contact rail (or busbar), the power supply device 9 (contact rail or busbar) can be installed on the track beam 6, and the collector shoe on the end car bogie 12 contacts the power supply device 9 to draw current and power the train system. When the power supply system uses batteries or fuel engines, the batteries and fuel power devices carried by the end car body 11 itself power the train system. Therefore, this system can select different power supply modes according to actual conditions and actual needs.

[0051] It should be further explained that when the power supply system is powered by a fuel power unit, a power unit 13 can be installed at the bottom of the end car bogie 12, and the power unit 13 can be set as a rotating motor, a fuel engine or an internal combustion engine. The power unit 13 is connected to the axle through a reduction mechanism and drives the rubber wheel 3 to rotate, thereby providing traction for the vehicle.

[0052] On the basis of the above embodiment, preferably, the CRRC 2 includes a CRRC body 21, a CRRC bogie 22 for supporting the CRRC body 21, a suspension module for cooperating with the reaction rail 7 to produce a suspension effect, and a suspension controller 23. The CRRC body 21 is arranged on the CRRC bogie 22, and the left and right sides of the CRRC bogie 22 are correspondingly provided with suspension modules. An anti-roll device for improving structural stability is provided between the suspension modules. A suspension electromagnet is provided at the bottom of the suspension module, and the suspension electromagnet is connected to the suspension controller 23. The suspension controller 23 is arranged on the chassis of the CRRC body 21.

[0053] It should be noted that the CRRC 2 is mainly used for transporting personnel, and the CRRC car body 21 runs on the reaction rail 7 in a suspended manner. The main material of the CRRC car body 21 is aluminum alloy, which mainly includes main components such as the chassis, side walls, end walls and roof. Below the CRRC car body 21 is the CRRC bogie 22. The CRRC bogie 22 is mainly composed of main components such as longitudinal beams, support arms and anti-roll devices. The main components are composed of aluminum alloy profiles connected by welding or fasteners. A suspension module is suspended on the support arm of the CRRC bogie 22. The suspension module is suspended by a suspension controller 23 installed on the chassis of the CRRC car body 21. The suspension electromagnet and the reaction rail 7 installed on the track beam 6 generate electromagnetic force to provide suspension force and guiding force for the vehicle.

[0054] During actual use, the shape, structure, size, position, etc. of the CRRC car body 21, the CRRC bogie 22, the suspension module and the suspension controller 23 can be determined according to actual conditions and actual needs.

[0055] Preferably, a secondary system 24 is provided between the CRRC car body 21 and the CRRC bogie 22 to effectively alleviate mechanical vibration between the CRRC car body 21 and the CRRC bogie 22 .

[0056] Preferably, a damping rod 25 is provided between the left end of the underframe and the left end of the CRRC bogie 22 , and between the right end of the underframe and the right end of the CRRC bogie 22 .

[0057] It should be noted that the damping rod 25 is used to connect the CRRC car body 21 and the CRRC bogie 22 to transmit the traction force of the CRRC bogie 22 to the CRRC car body 21 and maintain the stability of the CRRC car body 21.

[0058] In actual use, the shape, structure, size, position, etc. of the secondary system 24 and the damping rod 25 can be determined according to actual conditions and actual needs.

[0059] Based on the above embodiment, preferably, the main components of the end car 1 and the middle car 2 are all made of aluminum alloy. This can effectively reduce the vehicle load and structure, thereby making the train system more adaptable to lines and projects, and is particularly suitable for promotion in scenic areas with complex line environments and high investment cost control requirements.

[0060] Preferably, the end car 1 and the middle car 2 are both single-car single-bogie structures or single-car multi-bogie structures.

[0061] It should be noted that a single-vehicle single-bogie structure refers to a vehicle body arranged on a corresponding bogie, while a single-vehicle multi-bogie structure refers to a vehicle body arranged on multiple interconnected bogies, and the ratio of the vehicle body to the bogie can be adjusted and determined according to actual needs.

[0062] It should also be noted that the track beam 6, as the supporting structure of the entire system, can be flexibly formed as a simply supported beam or a continuous beam, depending on the line conditions. The track beam 6 can be made of either concrete or steel. The cross-section of the track beam 6 must meet the passability requirements of the different carriages in the train system. The end car 1 primarily passes through the upper plane of the track beam 6 with the assistance of the rubber wheels 3 and the guide device 14, while the middle car 2 passes through the track beam 6 by relying on the suspension and guide forces generated by the interaction between the suspension electromagnet and the reaction rail 7.

[0063] The semi-suspended maglev train transportation system provided by this invention possesses nearly all the advantages of maglev rail transit, including high operational safety, low noise, excellent environmental performance, strong line adaptability, and low construction and maintenance costs. Furthermore, by miniaturizing existing maglev systems, the system further reduces vehicle loads and structure, making the train more adaptable to different routes and projects. This makes it particularly suitable for deployment in scenic areas with complex rail environments and high investment cost control requirements. Furthermore, this system can complement existing urban rail transportation systems, further improving urban transportation systems.

[0064] This system features a train consisting of a terminal car (1) pulled by rubber wheels (3) coupled to several unpowered magnetically levitation train cars (2). This system seamlessly combines the advantages of both wheeled and magnetically levitation vehicles, with all car bodies arranged in a one-to-one or one-to-many arrangement with bogies. The train operates in a semi-suspended mode (the terminal car (1) is wheel-supported, while the train cars (2) are suspended). The suspended train cars (2) significantly enhance passenger comfort. Furthermore, since the train's power is derived entirely from the terminal car (1), and the two terminal cars (1) provide redundancy, system stability is further ensured.

[0065] In addition, this system uses a combination of rubber-wheel 3-traction and rack-rail 8-traction braking vehicles. Under good line conditions, only rubber-wheel 3-traction braking vehicles are used, and under special line conditions, rubber-wheel 3-traction and rack-rail 8-traction braking vehicles are combined. This makes the system highly adaptable to large longitudinal slopes such as high mountains and steep slopes and other special line conditions, greatly reducing the limitations of line conditions on system application.

[0066] This system, based on the existing maglev system, features a miniaturized and simplified design, reducing the structural dimensions and optimizing the system across all aspects, including vehicles, tracks, bridges, and lines. The optimized system reduces structural loads and dimensions while simplifying complex and expensive systems such as signaling, power supply, and station buildings, significantly reducing system investment. Furthermore, the independent, multi-carriage train system offers flexible marshaling, further reducing the train's turning radius and enhancing its adaptability to different lines, thereby enhancing product scalability and market competitiveness.

[0067] In addition, it should be noted that the directions or positional relationships indicated by "up and down", "left and right", etc. in this application are based on the directions or positional relationships shown in the accompanying drawings, and are only for the purpose of simplifying the description and facilitating understanding, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

The same or similar parts between the various embodiments can be referenced to each other. Any combination of all the embodiments provided by the present invention is within the scope of protection of this invention and will not be described in detail here.
