Description

Technical Field

[0001] This invention belongs to the field of transportation, and specifically relates to an air-suspended train. Background Technology

[0002] After the development of high-speed wheeled trains entered the 20th century, maglev trains emerged, represented by maglev technology. However, due to various reasons and problems, the development of maglev train technology has been relatively slow. Currently, high-speed rail and maglev transportation have become the mainstream technologies for high-speed land passenger transport, but both face urgent technological bottlenecks that need to be overcome. Traditional wheel-rail high-speed rail is limited by the adhesion characteristics between the wheel and rail, and its speed-up capability has a theoretical limit. Although high-speed maglev technology achieves contactless operation, it relies on strong magnetic fields and complex electromagnetic control systems, and has inherent drawbacks such as high initial construction costs, high dependence on permanent magnet materials, complex system operation and maintenance, and electromagnetic interference. Summary of the Invention

[0003] The purpose of this invention is to provide an air-levitated train to solve the problems of high cost, high dependence on permanent magnet materials, complex system operation and maintenance, and electromagnetic interference of magnetic levitation trains.

[0004] The technical solution of the present invention is: an air-suspended train, comprising a train body and a roadbed, with rails provided on the roadbed, a lifting air buoyancy chamber provided at the bottom of the train body, and multiple lifting pressure fans provided at the top of the lifting air buoyancy chamber, the lifting pressure fans discharging air downwards; a guide bracket provided at the bottom of the train body, the guide bracket being located inside the lifting air buoyancy chamber, a boss provided at the bottom of the guide bracket, the outer side of the boss being opposite to the inner side of the rails; and a turbocharged jet provided at the top of the train body.

[0005] As a further improvement of the present invention, the bottom surface of the guide bracket is opposite to the top surface of the track.

[0006] As a further improvement of the present invention, a load-bearing bracket is also provided at the bottom of the vehicle body, with the bottom surface of the load-bearing bracket facing the top surface of the track.

[0007] As a further improvement of the present invention, a longitudinal load-bearing main beam is provided at the bottom of the vehicle body. Flat sealing plates are sealed to both sides of the longitudinal load-bearing main beam, and side sealing plates are sealed to the outside of the flat sealing plates. End face sealing plates are provided at both ends of the longitudinal load-bearing main beam. The end face sealing plates are sealed to the longitudinal load-bearing main beam, the flat sealing plates, and the side sealing plates. The load-bearing main beam, the flat sealing plates, the side sealing plates, and the end face sealing plates together form a cushioned air buoyancy chamber, which is inverted on the roadbed base surface.

[0008] As a further improvement of the present invention, a reference steel bar is provided on the roadbed base surface, the reference steel bar is set along the track rail, and the reference steel bar is positioned opposite to the side sealing plate.

[0009] As a further improvement of the invention, the turbocharged jet engine is mounted on the top of the vehicle body via a turntable.

[0010] As a further improvement of the present invention, a muffler is provided at the tail of the turbocharged jet.

[0011] The beneficial effects of this invention are as follows: This invention incorporates a buoyancy chamber at the bottom of the vehicle body. This chamber, together with the roadbed surface, forms a sealed, buoyant space. A high-pressure airflow is continuously pumped into this space by a buoyancy fan, creating a boosted air buoyancy at the bottom of the vehicle body. This provides excellent air-lift support without relying on permanent magnets and avoids electromagnetic interference. This invention eliminates the need for wheels, guiding the vehicle body solely through guide brackets and rails, resulting in a simpler structure and easier maintenance. The vehicle body is driven by a turbocharged jet engine powered by electricity. The electrical system is relatively simple, low-cost, and consumes less energy. Furthermore, the turbocharged jet engine can be turned around via a turntable, eliminating the need for reversing. The train can achieve bidirectional, double-track operation through track changing. This invention utilizes existing train and track technologies, combined with innovative air-levitation technology, to create a completely new mode of transportation—a highly feasible air-levitation train technology.

Detailed Implementation

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] like Figure 1-6As shown, an air-suspended train includes a vehicle body 1 and a roadbed 8. A track 9 is provided on the roadbed 8. The track 9 adopts a standard track. A lifting air buoyancy chamber 12 is provided at the bottom of the vehicle body 1. Multiple lifting pressure fans 4 are provided on the top of the lifting air buoyancy chamber 12. The lifting pressure fans 4 are connected to fan motors 5 and the lifting pressure fans 4 exhaust air downwards. A guide bracket 14 is provided at the bottom of the vehicle body 1. The guide bracket 14 is located inside the lifting air buoyancy chamber 12. A boss 141 is provided at the bottom of the guide bracket 14. The outer side of the boss 141 is opposite to the inner side of the track 9. A turbocharged jet 20 is provided on the top of the vehicle body 1. The turbocharged jet 20 is electrically driven.

[0016] The bottom surface of the guide bracket 14 is opposite to the top surface of the track 9.

[0017] The bottom of the vehicle body 1 is also equipped with a load-bearing bracket 15, the bottom surface of which is opposite to the top surface of the track 9.

[0018] Guide brackets 14 are provided at the front and rear ends of the vehicle body 1, and a load-bearing bracket 15 is provided in the middle of the vehicle body 1. The guide brackets 14 and the load-bearing brackets 15 are symmetrically arranged on both sides of the vehicle body 1.

[0019] A longitudinal load-bearing main beam 13 is provided at the bottom of the vehicle body 1. Flat sealing plates 3 are sealed to both sides of the longitudinal load-bearing main beam 13. Side sealing plates 6 are sealed to the outside of the flat sealing plates 3 through corner plates 2. End face sealing plates 10 are provided at both ends of the longitudinal load-bearing main beam 13. The end face sealing plates 10 are sealed to the longitudinal load-bearing main beam 13, the flat sealing plates 3, and the side sealing plates 6. The load-bearing main beam 13, the flat sealing plates 3, the side sealing plates 6, and the end face sealing plates 10 together form a buoyancy chamber 12, which is inverted on the roadbed base surface. A buoyancy fan 4 is installed on the flat sealing plate 3.

[0020] A reference steel bar 7 is provided on the base surface of the roadbed 8. The reference steel bar 7 is set along the track rail 9 and is positioned opposite the side sealing plate 6. The reference steel bar 7 is laid on both sides of the track rail 9 to maintain the flatness of the base surface of the roadbed 8, thus creating a closed condition on both sides of the air buoyancy chamber 12.

[0021] The turbocharged jet 20 is mounted on top of the vehicle body 1 via a turntable 19.

[0022] The turbocharged jet 20 has a muffler 21 at its tail.

[0023] Air-suspended trains typically operate as single-unit trains, each with its own independent air-lift system and jet propulsion system. A power grid 17 is installed along track 9, and the power required by the train is supplied by the power grid 17 through pantograph 18 and transmitted to the various electrical components of the train.

[0024] When the car body 1 is not in a raised state, the bottom surface of the load-bearing bracket 15 and the outer side of the bottom surface of the guide bracket 14 are in contact with the rail surface of the track 9 to support the car body 1.

[0025] When the train starts, the lifting pressure fan 4 first inputs strong air force into the lifting air buoyancy chamber 12. Under the action of the lifting pressure fan 4 continuously inputting strong air force into the lifting air buoyancy chamber 12, when the air pressure in the lifting air buoyancy chamber 12 reaches the lifting air pressure standard, the car body 1 is suspended above the roadbed 8 base surface under the action of the lifting air pressure, with a lifting height of about 2mm. A very small amount of airflow overflows in the form of air film at the bottom edge of the side sealing plate 6 and the end sealing plate 10. The entire lifting air buoyancy chamber 12 can still maintain a good airtight effect, maintain the pressure in the lifting air buoyancy chamber 12, and ensure that the car body 1 can obtain a good and stable lifting levitation force under various operating conditions.

[0026] When the car body 1 is suspended in an air cushion state, the bottom surface of the load-bearing bracket 15 and the outer side of the bottom surface of the guide bracket 14 are separated from the rail surface of the track 9, so that the car body 1 is suspended above the track 9. The guidance and track change of the car body 1 during the driving process are completed by the protrusion 141 on the guide bracket 14 contacting the inner side of the track 9.

[0027] The car body 1 is driven by a turbocharged jet engine 20. Air enters the turbocharged jet engine 20 through the intake duct, where it is pressurized by the electric turbine motor driving the turbocharger blades. The pressurized air is then ejected at high speed through the muffler 21 at the rear, generating recoil thrust that propels the car body 1 forward. The turbocharged jet engine 20 can be rotated 180 degrees by a turntable 19 to change the direction of the high-pressure airflow, thus meeting the thrust requirements when the train is running in both directions.

[0028] When the train enters the station or needs to brake, the turbocharged jet 20 stops working, and at the same time, the pressure of the booster air in the bottom buoyancy chamber 12 is gradually reduced, so that the train gradually ends its levitation state. At this time, the bottom surface of the load-bearing bracket 15 and the outer side of the bottom surface of the guide bracket 14 fall back onto the rail surface of the track 9 and generate friction, reducing the speed of the train, and finally stopping the train safely.

[0029] Currently, the invention has achieved initial success in testing.

[0030] This invention solves the problems of high construction costs, high cost of construction, and high maintenance and operating costs in the operation and development of existing maglev trains, and has strong feasibility and practicality.
