Description

Technical Field

[0001] The present invention relates to a maglev high - speed bus transit system based on a composite special - shaped flange track, belonging to the field of transportation technology. In particular, it is a maglev high - speed bus transit system based on an upper and lower composite special - shaped flange track of an H - structure base beam (1) and a four - cantilever bogie, providing a solution for urban three - dimensional intelligent transportation. Background Art

[0002] With the high - quality development of the economy and people's demands for high - quality life, transportation, urban governance, environmental protection and low - carbon, higher and higher requirements are put forward for urban transportation. The number of private cars has increased rapidly, and there are more and more residents with 2 - 3 cars per household; thousands of shared cars have been put into use in multiple large cities. Rail transit plays an important role in solving the problem of urban traffic congestion. The average speed of the subway is 40 - 70 km / h, each car can carry 260 - 320 people, and the one - way hourly passenger volume is 30,000 - 70,000 people; the average speed of the light rail is 35 - 50 km / h, each car can carry 130 - 270 people, and the one - way hourly passenger volume is 15,000 - 35,000 people; each car of the straddle monorail can carry 100 - 160 people, with an average speed of 30 - 40 km / h, and the one - way hourly passenger volume is 10,000 - 25,000 people; each car of the suspended monorail can carry 75 - 120 people, with an average speed of 30 - 40 km / h, and the one - way hourly passenger volume is 10,000 - 15,000 people, etc., all of which have played an important role.

[0003] However, there is only one traffic mode on one line of rail transit such as subways, light rails, straddle monorails, suspended monorails, etc. The actual average operating speed is 20 - 40 km / h. To achieve a large passenger volume, each car has a large capacity of 100 - 320 people, with more than 60% standing passengers. It has a low operating speed, a large - capacity crowding, stops at every station, a single track, and a single passenger - carrying function in the bus operation mode. In the development of modern smart cities, citizens lack the experience of high - speed, efficient, comfortable and high - end public transportation travel happiness. Therefore, self - driving still accounts for a relatively large proportion. Summary of the Invention

[0004] The purpose of the present invention is: aiming at the above - mentioned problems and deficiencies, to provide a maglev high - speed bus transit system based on a composite special - shaped flange track, in particular, a maglev high - speed bus transit system based on an upper and lower composite special - shaped flange track of an H - structure base beam (1) and a four - cantilever bogie, making full use of urban low - altitude traffic resources. During the traffic peak, the upper and lower composite three - dimensional tracks operate the upper - flange special - shaped L - track vehicle (3V) and the maglev high - speed bus transit simultaneously. The ground bus takes 1 hour, while the bus on the upper and lower composite track takes 10 minutes, providing a full - seat, high - speed, efficient, environmental - protection, low - carbon, comfortable and high - end travel plan for citizens. During the non - traffic peak, buses and logistics vehicles share the track, achieving the maximum benefit of traffic resources. The present invention provides one of the solutions for the maglev high - speed bus transit system with a composite special - shaped flange track. Summary of the Invention

[0040] The above is an externally suspended maglev high-speed bus transit system based on a composite special-shaped flange track.

[0041] The present invention also provides an internally suspended maglev high-speed bus transit system based on a composite special-shaped flange track. The difference from the above externally suspended maglev high-speed bus transit system based on a composite special-shaped flange track is:

[0042] The difference of the lower flange special-shaped maglev track (20) is that the L-shaped steel support rail (2A) replacing the outer support rail (22) is installed on the inner side surfaces of the left and right lower flanges (2) to become the inner support rail. The intelligent stable guiding wheel track (24) is arranged on the inner side surfaces of the installation side plates (2B) of the left and right L-shaped steel support rails (2A). As Figure 1 shown in the lower right figure.

[0043] The difference of the support mechanism including the support steel wheels (53) and the protection steel wheels (56) is that the shafts of 2 to 8 or more support steel wheels (53) on the left and right are respectively installed on the upper parts of the outer side surfaces of the left and right bogie main beams (60), and the wheels are installed on the upper surface of the inner support rail L-shaped steel support rail (2A) of the track system. The maglev high-speed bus is called an inner-suspended maglev high-speed bus. When the maglev high-speed logistics vehicle stops running, the support steel wheels (53) support the weight of the whole vehicle; the shafts of 2 to 4 or more protection steel wheels (56) on the left and right are installed on the lower parts of the outer side surfaces of the left and right bogie main beams (60), and the wheels are correspondingly below the bottom surface of the inner support rail L-shaped steel support rail (2A). The distance between the upper wheel rim of the protection steel wheel (56) and the bottom surface of the L-shaped steel support rail (2A) is designed to ensure the safety distance that the linear motor prevents the secondary and primary from colliding and scratching, and ensures that the electromagnet (4A) and the U-shaped steel rail (21) of the track system will not be sucked and stuck. As Figure 1 shown in the lower right figure, Figure 3 b, Figure 6 as shown in b.

[0044] The difference of the intelligent stable guiding system is that the servo electric cylinder (28) is installed on the bogie main beam (60), and the stable guiding wheel (23) corresponds to the intelligent stable guiding wheel track (24) arranged on the inner side surfaces of the installation side plates (2B) of the left and right inner support rails L-shaped steel support rails (2A); as Figure 3 b, Figure 6 as shown in b.

[0045] The difference of the power receiving mechanism (4) is that one end of the power receiving mechanism (4) is installed on the outer side of the electromagnet (4A), so that the power receiving shoe of the other end of the power receiving mechanism (4) keeps close contact with the lower power supply rail (42) for normal power supply; as Figure 3 b, Figure 6 as shown in b.

[0046] Others are completely the same as the above-mentioned outer-suspended maglev high-speed bus system based on the composite special-shaped flange track.

[0047] The present invention provides an operation method of a maglev high-speed bus system based on a composite special-shaped flange track:

[0048] 1) Under the management and control of systems such as the operation system cloud platform, track signaling system, safe operation system, vehicle control system, and unmanned intelligent driving system, the maglev high-speed bus departs from the originating station on the composite special-shaped flange track system; the station management system of the originating station sends the number of passengers boarding at this station, the corresponding carriage number and door number, and the information of the destination stations of the passengers to the vehicle Internet of Things system. The vehicle Internet of Things system transmits the information to the vehicle control system through the internal line. The vehicle control system cross-verifies the number of passengers and the number of empty seats in each row through the in-vehicle video monitoring and identification system, and cross-verifies with the information received from the station management system. Preferably, the maglev high-speed bus is a full-seat high-end vehicle, and each door corresponds to 6 to 8 seat positions.

[0049] 2) The equipment status, real-time position, running speed, etc. of the maglev high-speed bus running on the composite special-shaped flange track system are sent to the operation system cloud platform and the vehicle Internet of Things systems of the 3 to 5 vehicles in front and behind through the vehicle Internet of Things system in real time, so as to achieve the safe coordinated operation of the 3 to 5 vehicles in front and behind. For example, if a vehicle needs to brake urgently due to reasons, the 3 to 5 vehicles behind will decelerate synchronously and transmit to the subsequent vehicles in turn to achieve safe coordinated operation; the number and corresponding position information of the empty seats in the vehicle, the information of the destination stations of the passengers, the status of the passengers in the vehicle (preventing emergencies), etc. are transmitted to the vehicle Internet of Things system through the internal cable of the vehicle control system, and the vehicle Internet of Things system sends them to the operation system cloud platform and the station management system in front in real time.

[0050] 3) If the passengers in this train are full, this vehicle will start the operation mode of going directly to the nearest destination station. The vehicle control system sends the information that this vehicle will run directly to the operation system cloud platform and the nearest destination station through the vehicle Internet of Things system. The vehicle control system issues a direct running instruction and the information of the nearest destination station to the unmanned intelligent driving system. This vehicle will run directly to the nearest destination station at a speed of 160 to 200 kilometers per hour, providing high-speed, efficient, comfortable, and high-end transportation services in the context of congested cities.

[0051] 4) Before the maglev high-speed bus arrives at the station ahead, the station management system has displayed the number of empty seats at each door of the train formation about to arrive at the corresponding door waiting area of the station. After the passengers punch the card and select the name of the destination station they are going to according to the prompt, the passengers can enter the corresponding door waiting area to achieve accurate boarding of the passengers.

[0052] 5) After the maglev high-speed bus arrives at the station, passengers get off first and then get on. The passengers who have just got off swipe their cards one by one and walk out of the waiting area at the car door. If there is 1 passenger in the car who does not get off after arriving at the destination station, the number of passengers swiping their cards and walking out of the waiting area at the car door will be 1 less, and 1 passenger waiting to get on the bus will still stay in the waiting area at the car door and cannot get on the bus. The waiting area at the car door of the station will automatically remind passengers to wait for the next bus; if a passenger gets off in advance, the number of passengers swiping their cards and walking out of the waiting area at the car door will be 1 more, and this empty seat information will be notified to the next station.

[0053] 6) For the maglev high-speed bus that has just left the station, if the passengers in this train are full, the operation in 3) will be repeated.

[0054] 7) The operation system cloud platform calculates and performs image recognition based on the big data of the passenger flow at each station, and adopts an operation mode of direct arrival with empty cars for stations with large passenger flows, quickly relieving the dense passenger flow, improving the traffic quality of citizens' travel, enhancing the urban operation efficiency, and realizing the intelligent transportation of a smart city.

[0055] The above numbers are only for the convenience of narration and do not represent the actual operation sequence. Each of the above numbers can be regarded as an operation unit of the high-speed intelligent bus system. During operation, the sequence of operation units can be adjusted according to the actual situation, and even the operation units can be increased or decreased. Parts not detailed in the present invention can all adopt existing technologies.

[0056] The advantages of the present invention are:

[0057] 1. The composite special-shaped flange track that is vertically and horizontally compounded based on the H-structured base beam enables the vertical structural strength, stiffness, bending resistance, and the horizontal structural strength, stiffness, bending resistance, and torsional resistance to enhance each other, achieving lightweight, material-saving, energy-saving, and low-carbon design. Combined with the lightweight of the vehicle, the total weight of the composite track is reduced by 20% - 30% compared with the total weight of two single tracks with the same function. The minimum turning radius of the composite special-shaped flange track is 20 meters, and the climbing ability reaches 100‰. The project cost is 1 / 3 - 1 / 2 of that of the light rail. The line has strong adaptability, less land occupation, less demolition, low comprehensive cost, and the operation cost is 2 / 3 of that of the light rail.

[0058] 2. The maglev high-speed bus transit system of the present invention is intelligently driverless, with a designed speed of 160 - 200 km / h. It can intelligently implement direct departure of empty vehicles for rapid evacuation at stations with dense passengers. The fully loaded vehicles will intelligently identify and directly reach the nearest destination station of the passengers. The one-way passenger volume can reach 43,200 - 76,800 people per hour. During non-peak passenger traffic, it shares the track with high-speed logistics vehicles, maximizing the efficiency of traffic resources. The maximum sway angle of the four-cantilever bogie maglev high-speed bus is about 1°, solving the technical problem of the sway of 4° - 15° in the single-cantilever bogie carriage, making the operation of the suspended vehicle more stable. It provides a high-end transportation solution for smart cities that is all-seat, high-speed, efficient, comfortable, energy-saving, low-carbon, environmentally friendly, and has low noise.

[0059] 3. It operates safely and environmentally friendly. The design of the composite special-shaped flange track and the structure of the maglev high-speed bus will never derail; the self-provided battery can automatically charge the track to enable the vehicle to run safely to the next station; the new energy system provides environmentally friendly new energy while taking into account the function of the safety evacuation passage; the vehicle Internet of Things system and the operation system cloud platform enable the first 3 - 5 vehicles in the front and back to run synchronously and safely in coordination; the synergistic effect of hardware and software provides multiple guarantees for safety.

[0070] Embodiment 1

[0071] The structures and functions of the bogie 6, the cantilever steering mechanism 6A and the four-cantilever bogie.

[0072] The four-cantilever bogie is an important component of the maglev high-speed bus. The four-cantilever bogie includes a bogie 6 and a cantilever steering mechanism 6A, and the cantilever steering mechanism 6A is installed below the bogie 6.

[0073] The bogie 6 includes a bogie main beam 60 and a bogie connecting beam 61; on the same horizontal plane, one bogie main beam 60 is placed longitudinally and vertically in parallel and mirror-symmetrically on the left and right, and one bogie connecting beam 61 is arranged at the front and rear of the upper ends of the left and right bogie main beams 60 to connect the two bogie main beams 60 into a gantry channel-shaped three-dimensional structure; the bogie main beam 60 is an inverted T-shaped three-dimensional longitudinal beam member, including a vertical rectangular three-dimensional plate beam and a horizontally placed bogie main beam base 62 perpendicularly connected thereto; the left and right sides of the bogie main beam base 62 are asymmetric structures, and the main function of the short side inside the base is to increase the thickness to enhance the structural strength for installing the cantilever steering mechanism 6A, which is specifically designed by professionals according to needs; the longitudinal outer side of the long side of the bogie main beam base 62 is an electromagnet mounting plate 63, which is designed by professionals according to the installation dimensions of the electromagnet and the support mechanism; the upper surfaces of the left and right bogie main beams 60 are both linear motor mounting surfaces 64 for installing the primary of the linear motor.

[0074] The cantilever steering mechanism 6A includes a suspension column 66, a buffer spring 67, an air spring 68, a damper 6M, and a steering mechanism 6P. The bottom end of the suspension column 66 is provided with a suspension column base 69 for bearing the weight of the carriage. The suspension column 66 is successively installed with a suspension column base 69, an air spring 68, a suspension bracket 6B, and a buffer spring 67 from bottom to top. The damper 6M is installed between the top of the suspension bracket 6B and the suspension column base 69, and the steering mechanism is installed on the suspension bracket 6B. The suspension bracket 6B is a U-shaped frame structure. Its bottom is a suspension beam mounting seat for mounting on the top of the carriage, and the suspension beam mounting round holes at the top are used to sleeve on the suspension column 66. On both sides of the suspension column base 69, there is a damping mounting plate 6G respectively. On both the left and right sides of the air spring 68, there is a damper 6M. The upper end of the damper 6M is installed below the top of the suspension bracket 6B, and the lower end is installed on the damping mounting plate 6G of the suspension column base 69. The steering mechanism 6P includes a spring seat 6H, a spring 6J, a lever 6K, and a support 6L. At the front end of the suspension column base 69, there is a support 6L. The outer end face of the support 6L is installed at the central part of the lever 6K. On the inner sides of both ends of the lever 6K, there is a spring 6J respectively. The other end of the spring 6J is installed on the spring seat 6H. One spring seat 6H on each of the left and right sides is installed on the outer side surface of the suspension bracket 6B.

[0075] Four-cantilever bogie. On the front and rear ends of the bottom surfaces of the left and right bogie main beam bases 62 of the bogie 6, a cantilever steering mechanism 6A is installed respectively, with a total of four suspension arms, and the bogie is called a four-cantilever bogie. During the operation of the vehicle, the four-cantilever bogie is installed on the top of the carriage by using its suspension beam mounting seat, playing the role of supporting the vehicle weight and guiding the vehicle to turn. The prominent feature of the four-cantilever bogie is that it runs more smoothly. Compared with the single-cantilever bogie commonly used at present, the design of the four-cantilever bogie greatly improves the torque of the vehicle to reduce shaking and swaying, and increases the support points. The coordinated design of the two dampers 6M on the left and right sides between the suspension bracket 6B and the suspension column base 69 and the air spring 68 and the design of the steering mechanism 6P further absorb the left and right shaking forces or the left and right swaying forces and energies when turning of the carriage in the forward direction. The buffer spring 67, the damper 6M, and the air spring 68 jointly absorb the up and down vibration forces and energies of the carriage, making the impact on the bogie smaller, and preferably solving the technical problem of the 4° - 15° shaking of the carriage caused by the combined action of the operation of the single-cantilever bogie vehicle and the wind load. The maximum shaking angle of the four-cantilever bogie is about 1°, making the operation of the suspended vehicle more stable.

The lower power supply rail 42 is installed on the outer side surface of the H-shaped structural beam 1 of the track system, and the lower power supply rail 42 is powered by a cable arranged in the power cable hole 1A; one end of the current collection mechanism 4 is installed at the top of the support frame 5, so that the current collection shoe at the other end of the current collection mechanism 4 is in close contact with the lower power supply rail 42. Whether the maglev vehicle stops and lands on the outer support track 22, or is in a suspended state, or is in an operating state, close contact and normal power supply can be maintained between the current collection mechanism 4 and the lower power supply rail 42. The linear motor is a long-secondary short-primary structure, including a linear motor secondary 4D and a linear motor primary 4E; one linear motor secondary 4D is installed on each side of the bottom surfaces of the structural end beam 10 and the structural middle beam 11 of the composite special-shaped flange track system; one linear motor primary 4E is installed on the linear motor mounting surface 64 on the upper surface of the bogie main beam 60, corresponding to the position of the linear motor primary 4E; preferably, one linear motor secondary 4D is installed in the middle of the bottom surfaces of the structural end beam 10 and the structural middle beam 11, and one linear motor primary 4E is installed corresponding to the position of the linear motor secondary 4D on the upper surface of the bogie connecting beam 61 or on the linear motor mounting plate 6C.

Such as Figure 3 , Figure 5 , Figure 6 as shown.

[0086] The described safe operation system includes an image radar recognition and ranging device 7A, a vehicle-mounted battery system, a braking system, and an intelligent stability and guidance system.

When the external power supply suddenly cuts off, the vehicle-mounted battery system provides power for the whole vehicle, enabling the vehicle to safely run to the nearest one or two stations. The braking system includes soft braking, mechanical braking, and a braking control system. The soft braking is achieved by the reverse thrust of the linear motor. When the maglev high-speed bus needs to brake while running at high speed, first, the braking control system operates the linear motor to apply reverse thrust, so that the maglev high-speed bus accelerates deceleration through the reverse soft braking thrust. When the speed drops below 5 km / h, the braking control system automatically activates the mechanical braking, and at the same time controls the reverse thrust applied by the linear motor to gradually decrease to zero. The mechanical braking consists of a brake caliper mechanism 54 and a U-shaped steel rail 21. The brake caliper mechanism 54 is installed on the support frame 5 and the magnetic pole legs corresponding to the outside of the U-shaped steel rail 21. When the maglev high-speed bus needs mechanical braking, the brake caliper mechanism 54 clamps the magnetic pole legs to implement mechanical braking. The braking control system is installed in the cab 71. The braking control system monitors and controls both soft braking and mechanical braking, and accepts instructions from the unmanned intelligent driving system and the vehicle control system to control the braking system.

The stable guiding wheel 23 is installed on the telescopic rod 27, and the telescopic rod 27 is installed in the servo electric cylinder 28. The stable guiding wheel 23 corresponds to the intelligent stability and guidance wheel track (24) on the track. According to the running state of the vehicle, or the magnitude of the lateral wind force, or the magnitude of the turning centrifugal force, or the magnitude of the vehicle running offset, the intelligent stability and guidance control system controls the distance between the stable guiding wheel 23 and the guiding wheel track to maintain a distance of 0 - 30 mm or a wider distance, precisely controlling the magnitude of the auxiliary guiding force and the magnitude of the balance and stability force, minimizing the running resistance to the greatest extent, and ensuring the vehicle runs safely, quickly, and efficiently along the set track.

[0098] The H-structured base beam 1 includes vertical flange beams, structural end beams 10, and structural middle beams 11. On the same horizontal plane, two vertical flange beams are longitudinally arranged in parallel and mirror-symmetrically on the left and right. At both ends of the two vertical flange beams, a structural end beam 10 is provided respectively. Between the two structural end beams 10, 0 to 20 or more structural middle beams 11 are longitudinally and evenly distributed. The upper surfaces of the structural end beam 10 and the structural middle beams 11 are on the same plane, and the lower surfaces are also on the same plane, connecting the left and right vertical flange beams in the middle area into an integral structure to form the H-structured base beam 1. A weight-reducing hole 14 is provided in both the structural end beam 10 and the structural middle beam 11. The vertical flange beam is a hollow structure, and the vertical flange beam and its joints with the structural end beam 10 and the structural middle beam 11 are hollow structures, realizing the optimization and lightweight of the structure of the H-structured base beam 1. The structural end beam 10 is installed in the middle area of the beam on the relatively inner side of the vertical flange beam. The upper flange 3 and the lower flange 2 of the H-structured base beam 1 are characterized by an asymmetric structure. The upper flange 3 is optimized and thinned to achieve lightweight, material saving, energy saving, and low carbon.

[0099] The upper flange special-shaped L track 30 includes an upper flange 3 and an L-structured track. The L-structured track is an L-shaped structural track composed of an L-shaped vertical side guard plate 31 and an L-shaped horizontal side track surface 32. There is a 90-degree angle between the L-shaped vertical side guard plate 31 and the L-shaped horizontal side track surface 32.

The characteristics of the upper flange special-shaped L track 30 are that the L-shaped vertical side guard plate 31 and the L-shaped horizontal side track surface 32 in the vertical direction enhance the structural strength, stiffness, bending resistance, and torsional resistance of the H-structured base beam 1 in the vertical and transverse directions. Therefore, the thickness of the upper flange 3 is scientifically thinned and lightened, and the design of the relatively wide L-shaped horizontal side track surface 32 ensures that the track surface has sufficient width and load-bearing capacity.

[0100] The prominent features of the upper flange special-shaped L track 30 of the present invention are the L-shaped wide track surface design, a designed speed of 120 - 160 km / h, and an intelligent stable guiding guarantee system.

As Figure 1 、 Figure 2 shown.

[0103] Operation method of the maglev high-speed bus transit system based on the composite special-shaped flange track:

[0104] 1) The maglev high-speed bus is a vehicle with all seats for high-end comfort. Each door corresponds to 6 - 8 seat positions and departs from the station driverless on the composite special-shaped flange track system; the station management system of the departure station sends the information of the number of passengers boarding at this station, the corresponding carriage number and door number, and the destination stations of the passengers to the vehicle Internet of Things system. The vehicle Internet of Things system internally transmits the information to the vehicle control system, and the vehicle control system cross-verifies the number of passengers and the number of empty seats in each row through the in-vehicle video monitoring and identification system and cross-verifies with the information received from the station management system;

[0105] 2) The equipment status, location, speed, etc. of the maglev high-speed bus running on the composite special-shaped flange track system are sent to the operation system cloud platform and the vehicle Internet of Things systems of the 3-5 vehicles before and after in real time through the vehicle Internet of Things system, so as to realize the safe collaborative operation of the 3-5 vehicles before and after. The number and corresponding position information of the empty seats in the vehicle, the information of passengers arriving at the destination station, the status of passengers in the vehicle to prevent emergencies, etc. are transmitted to the vehicle Internet of Things system through the internal cables of the vehicle control system, and the vehicle Internet of Things system sends them to the operation system cloud platform and the front station management system in real time.

[0106] 3) If the passengers in this train are full, this vehicle will start the operation mode of going directly to the nearest destination station. The vehicle control system sends the information that this vehicle will run directly to the operation system cloud platform and the nearest destination station through the vehicle Internet of Things system. The vehicle control system issues a direct operation instruction and the information of the nearest destination station to the unmanned intelligent driving system, and this vehicle will go directly to the nearest destination station at a speed of 160-200 km / h.

[0107] 4) Before the maglev high-speed bus arrives at the front station, the station management system has displayed the number of empty seats at each door of the formation vehicle about to arrive at the corresponding door waiting area of the station. After the passengers punch the card and select the name of the destination station they are going to according to the prompt, the passengers can enter the corresponding door waiting area to achieve accurate boarding of passengers;

[0108] 5) After the maglev high-speed bus arrives at the station, passengers get off first and then get on. The passengers who have just got off swipe their cards one by one and walk out of the door waiting area. Suppose there is 1 passenger who does not get off after arriving at the destination station in the vehicle, then the number of passengers swiping their cards and walking out of the door waiting area will be 1 less, and 1 passenger waiting to get on the bus will still stay in the door waiting area and cannot get on the bus. The station will automatically use voice to remind the passengers at this door waiting area to please wait patiently for the next bus, which will arrive in 1.5 or 2 minutes; if a passenger gets off in advance, the number of passengers swiping their cards and walking out of the door waiting area will be 1 more, and this empty seat information will be notified to the next station;

[0109] 6) For the maglev high-speed bus that has just left the station, if the passengers in this train are full, the operation in 3 will be repeated.

[0110] 7) The operation system cloud platform calculates based on the big data of the passenger flow of each station and image recognition, and adopts the operation mode of direct arrival with empty vehicles for the stations with large passenger flow, quickly dispersing the dense passenger flow, improving the quality of citizens' travel and the operation efficiency of the city.

The intelligent stable guiding wheel track (24) is arranged on the inner side surfaces of the mounting side plates (2B) of the left and right L-shaped steel support rails (2A). As Figure 1 shown in the right lower figure.

[0118] The difference in the support mechanism including the support steel wheels (53) and the protection steel wheels (56) is that the axles of 2 to 8 or more support steel wheels (53) on the left and right are respectively installed on the upper parts of the outer side surfaces of the left and right bogie main beams (60), and the wheels are installed on the upper surfaces of the inner support rails L-shaped steel support rails (2A) of the track system.

The distance between the upper wheel rims of the protection steel wheels (56) and the bottom surfaces of the L-shaped steel support rails (2A) is designed to ensure a safety distance that prevents the secondary and primary of the linear motor from colliding and scratching and ensures that the electromagnet (4A) and the U-shaped steel rail (21) of the track system will not be attracted and stuck. As Figure 1 shown in the right lower figure, Figure 3 b, Figure 6 as shown in b.

[0119] The intelligent stable guiding system is different in that the servo electric cylinder (28) is installed on the main beam (60) of the bogie, and the stable guiding wheel (23) corresponds to the intelligent stable guiding wheel track (24) on the inner side of the mounting side plate (2B) of the left and right inner support track L-shaped steel support rails (2A); as Figure 3 b、 Figure 6 as shown in Figure b.
