Description
Technical Field
[0001] This invention relates to the field of straddle-type vehicle bogie technology, specifically to an intelligent transmission device for a single-axle straddle-type vehicle bogie. Background Technology
[0002] The straddle-type bogie is a core component of straddle-type monorail trains, which run on a single track. Its structural design allows it to straddle and sit on the track. Located on the train chassis, the bogie serves as the mounting base for the wheel system, undertaking multiple functions including supporting the entire vehicle weight, guiding the train along the track, and absorbing and mitigating shocks and vibrations generated during operation. Compared to traditional multirail railway vehicles, straddle-type bogies must adapt to the unique structure of a monorail, typically including precisely designed guide wheels, stabilizing wheels, and a power transmission system. These components work together to ensure the stability and safety of the train on the monorail.
[0003] However, in existing straddle-type vehicle bogies, the guide wheels mounted on both sides are affected by centripetal force when running at high speeds. The existing guide wheel assemblies lack the ability to adaptively adjust according to changes in centripetal force, which makes it impossible to maintain precise guidance and fit between the guide wheels and the track at all times. In addition, it is inconvenient to monitor and process the guide wheels in real time during high-speed operation, which limits its effectiveness and reliability in practical applications.
[0004] Therefore, the present invention aims to design a novel intelligent transmission device for a single-axle bogie of a straddle-type vehicle, in order to solve the problems existing in the prior art and improve the operating performance and safety of straddle-type monorail trains. Summary of the Invention

The output ends of the two sets of electric push rods are respectively rotatably connected to guide wheels.

The guide assembly is rotatably connected to the four corners of the bottom of the bogie body through a first connecting flange and a second connecting flange to improve the overall steering performance of the bogie body and reduce the wear of the guide wheels when they go through curves on both sides of the track beam. Through the airtight cavity opened inside the first bogie body and the damper installed at the bottom of the connecting end block, when the straddle-type vehicle bogie generates centripetal force at high speed on the track beam, the first support component can move downward at the bottom of the bogie body under the elastic force of the damper, ensuring that the guide wheels and both sides of the track beam are always in a guiding fit, thereby ensuring the stability of the train at high speed.

The transmission gear plate is structurally matched with the transmission gear disk, and the transmission gear plate and the transmission gear disk are meshed.
[0019] Based on the above technical features, this solution uses a structural design that connects the transmission tooth plate and the transmission gear disk in an meshing manner, allowing the transmission tooth plate to slide to the left or right inside the first housing under the drive of the transmission gear disk.

[0022] Preferably, in the above-mentioned intelligent transmission device for a straddle-type vehicle single-axle bogie, a first compression spring is connected to the middle of both ends of the transmission tooth plate, and two sets of guide grooves are also provided at the edges of both ends of the transmission tooth plate. The guide grooves are matched with the slide rail structure, and the guide grooves and the slide rail are in sliding fit. A pusher is also connected to the top of the transmission tooth plate.
[0023] Based on the above technical features, when the guide wheel changes from turning around the sides of the track beam to traveling in a straight line, the first compression springs installed at both ends of the transmission tooth plate can reset the swing-adjusted guide wheel, so that the guide wheel can maintain a guiding fit with both sides of the track beam when turning or traveling in a straight line.

At the same time, the operation of the straddle-type vehicle bogie on the track beam can be inferred and judged based on the monitored and recorded electrical signal data, thereby improving the safety of train operation.
[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0045] Please see Figures 1 to 10 This invention provides a technical solution for an intelligent transmission device for a single-axle bogie in a straddle-type vehicle:
[0046] A single-axle bogie intelligent transmission device for straddle-type vehicles includes a bogie body 1 located on a track beam. A drive assembly 2 is installed on the top of the bogie body 1, and a running wheel assembly 3 is connected to the middle of the drive assembly 2. Guide components 4 are installed at the four corners of the bottom of the bogie body 1. The guide components 4 include a first support component 5, a damping plate 6 is installed on one side of the first support component 5, and two sets of electric push rods 7 are installed on one side of the first support component 5. The output ends of the two sets of electric push rods 7 are rotatably connected to guide wheels 8. A first transmission component 9 is installed at each of the four corners of the bogie body 1. A second transmission component 10 is connected to the side of the bogie body 1 near the first transmission component 9. Safety wheels 11 are installed at the middle of both ends of the bogie body 1. A first bearing seat 12 is installed on both sides of the top of the bogie body 1. Arc-shaped grooves 13 are also opened on both sides of the bogie body 1 near the first bearing seat 12.
[0047] The first transmission assembly 9 includes a second bearing seat 14, which is located at the four corners of the bogie body 1. A first connecting flange 15 is installed at one end of each of the two sets of second bearing seats 14. A transmission gear disk 16 is also installed at the end of the second bearing seat 14 away from the first connecting flange 15. By adding the second bearing seats 14 at the four corners of the bogie body 1, the first connecting flange 15 and the transmission gear disk 16 can be rotatably connected to the four corners of the bogie body 1. The first support component 5 includes a first frame 17. A connecting end block 18 is installed in the middle of the first frame 17. An air spring 19 is also connected between the connecting end block 18 and the first frame 17. The air spring 19 installed between the connecting end block 18 and the first frame 17 adopts the annular airbag or annular pneumatic spring in the prior art. It has an annular or cylindrical cross-section and is a sealing element that uses the compressibility of the closed gas to provide elastic force, which can improve the airtightness of the connection between the connecting end block 18 and the first frame 17.
[0048] The first frame 17 has an airtight cavity 20 inside. Both the top of the first frame 17 and the bottom of the connecting end block 18 have annular grooves 21. These annular grooves 21 are structurally matched with the air spring 19, and the fit between the annular grooves 21 and the air spring 19 is transitional. An electrically controlled air valve 22 is also installed on the outer side of the first frame 17. This electrically controlled air valve 22 is a type of valve in the prior art that uses electrical signals to control the flow of gas or liquid, and can adjust the gas flow according to usage conditions. In the sealed state of the airtight cavity 20, a second connecting flange 23 is installed on the top of the connecting end block 18, and a damper 24 is connected to the bottom of the connecting end block 18. A stop block 25 is also installed at the bottom of the damper 24. The stop block 25 matches the structure of the airtight cavity 20. In this design, the structural design between the stop block 25 and the airtight cavity 20 achieves a precise match. This design cleverly avoids the possibility of relative rotation between the stop block 25 and the first support component 5. In addition, the stop block 25 can also act as a piston inside the airtight cavity 20.
[0049] During operation, the guide assembly 4 can be rotatably connected to the four bottom corners of the bogie body 1 via the first connecting flange 15 and the second connecting flange 23. This can improve the overall steering performance of the bogie body 1 and reduce wear on the guide wheels 8 when they curve on both sides of the track beam. Through the airtight cavity 20 opened inside the first frame 17 and the damper 24 installed at the bottom of the connecting end block 18, the damper 24 is composed of a piston rod and shock-absorbing spring of existing technology. When the straddle-type vehicle bogie generates centripetal force at high speed on the track beam, the first support component 5 can move downward at the bottom of the bogie body 1 under the elastic force of the damper 24. This allows the guide wheels 8 installed on the first support component 5 to always be in a guiding fit with both sides of the track beam when they curve on both sides of the track beam, thereby ensuring the stability of the train at high speed.
[0050] As one embodiment of the present invention, such as Figures 5 to 7 As shown, the second transmission assembly 10 includes a first housing 26. A sealing plate 27 is installed on one side of the first housing 26. Two sets of slide rails 28 are connected to the inner side of the sealing plate 27. A transmission toothed plate 29 is also provided between the sealing plate 27 and the first housing 26. The transmission toothed plate 29 is structurally matched with the transmission gear disk 16. The transmission toothed plate 29 and the transmission gear disk 16 are meshed. Through the structural design of the meshing connection between the transmission toothed plate 29 and the transmission gear disk 16, the transmission toothed plate 29 can slide to the left or right inside the first housing 26 under the drive of the transmission gear disk 16.
[0051] A second frame 30 is connected to both sides of the drive assembly 2. A third frame 31 is connected to the bottom of the second frame 30. A damping rod 32 is also provided between the two ends of the third frame 31. The damping rod 32 is matched with the structure of the damping plate 6. The damping rod 32 and the damping plate 6 are slidably connected. A rotating rod 33 is installed at the bottom of the drive assembly 2. Guide slide rods 34 are connected to both sides of the drive assembly 2 near the rotating rod 33. The guide slide rods 34 are matched with the structure of the arc-shaped slide groove 13. The guide slide rods 34 and the arc-shaped slide groove 13 are slidably engaged. Through the structural design of the sliding engagement between the guide slide rods 34 and the arc-shaped slide groove 13, the drive assembly 2 and the traveling wheel assembly 3, which are used for the top swing adjustment of the bogie body 1, can play a guiding and limiting role, and can prevent the drive assembly 2 and the traveling wheel assembly 3 from swinging too much at the top of the bogie body 1.
[0052] During operation, when the straddle-type vehicle bogie travels through a curve on the track beam, the guide wheels 8 installed at the bottom of both sides of the bogie body 1 will swing adaptively along the curvature of both sides of the track beam. Through the second frame 30 and the third frame 31 installed on both sides of the drive assembly 2, the guide wheels 8 in the swinging state can also drive the drive assembly 2 and the travel wheel assembly 3 hinged at the top of the bogie body 1 to swing synchronously, so that the travel path of the travel wheel assembly 3 can perfectly fit the curvature of the track beam, thereby reducing the wear and other problems of the travel wheels when traveling through curves on the track beam.
[0053] As one embodiment of the present invention, such as Figures 8 to 10 As shown, a first compression spring 35 is connected to the middle of both ends of the transmission gear plate 29. Two sets of guide grooves 36 are also provided on the edges of both ends of the transmission gear plate 29. The guide grooves 36 are matched with the slide rail 28 in structure, and the guide grooves 36 and the slide rail 28 are in sliding fit. A pusher 37 is also connected to the top of the transmission gear plate 29. When the guide wheel 8 changes from turning around the sides of the track beam to straight travel, the first compression springs 35 installed at both ends of the transmission gear plate 29 can reset the swing-adjusting guide wheel 8, so that the guide wheel 8 can maintain a guiding fit with the sides of the track beam when turning or traveling in a straight line. A first slot 38 is provided in the middle of one side of the first cover 26. The first slot 38 matches the structure of the transmission gear disk 16. A second slot 39 is provided in the top of the first cover 26. The second slot 39 matches the structure of the pusher 37. The second slot 39 and the pusher 37 are in sliding fit. Microcontrollers 40 are also provided on both sides of the first cover 26 near the second slot 39. Through the structural design of the sliding fit between the second slot 39 and the pusher 37, when the guide wheel 8 drives the transmission gear plate 29 to slide to the left or right inside the first cover 26 due to bending, it can drive the pusher 37 installed on the top of the transmission gear plate 29 to move synchronously.
[0054] The microcontroller 40 includes a second housing 41, inside which a guide adjustment groove 42 is provided. An adjustment push block 43 is connected inside the guide adjustment groove 42, and the adjustment push block 43 is structurally matched to the guide adjustment groove 42. A second compression spring 44 is connected to one side of the adjustment push block 43. A contact switch 45 is also provided at the end of the second compression spring 44 away from the adjustment push block 43. The contact switch 45 is electrically connected to the electric push rod 7 and the electric control valve 22. In this solution, the microcontroller 40 consists of the second housing 41, the guide adjustment groove 42, the adjustment push block 43, and the second compression spring. Composed of 44 and contact switch 45, when the guide wheel 8 causes the transmission tooth plate 29 to slide to the left or right inside the first cover 26 due to bending, it can drive the pusher 37 mounted on the top of the transmission tooth plate 29 to move synchronously. When the pusher 37 moves to the left or right and presses against the contact switch 45, it can trigger the generation of an electrical signal through the contact switch 45. The electrical signal can be used to monitor and record the real-time operation of the guide wheel 8. At the same time, the operation of the straddle-type vehicle bogie on the track beam can be inferred and judged based on the monitored and recorded electrical signal data, thereby improving the safety of train operation.
[0055] During operation, microcontrollers 40 are installed on both sides of the top of the first cover 26. Each microcontroller 40 consists of a second cover 41, a guide adjustment groove 42, an adjustment push block 43, a second compression spring 44, and a contact switch 45. When the guide wheel 8 slides to the left or right inside the first cover 26 due to bending, it can drive the pusher 37 installed on the top of the transmission tooth plate 29 to move synchronously. When the pusher 37 moves to the left or right and presses against the contact switch 45, an electrical signal can be generated by triggering the contact switch 45. The electrical signal can be used to monitor and record the real-time operation of the guide wheel 8. At the same time, the operation of the straddle-type vehicle bogie on the track beam can be inferred and judged based on the monitored and recorded electrical signal data, thereby improving the safety of train operation.
[0056] Working Principle: The straddle-type vehicle bogie designed in this invention mainly consists of a bogie body 1, a drive assembly 2, a running wheel assembly 3, and a guide assembly 4. The guide assembly 4 includes a first support component 5, a damping plate 6, an electric actuator 7, and guide wheels 8. This guide assembly 4 is rotatably connected to the four bottom corners of the bogie body 1 via a first connecting flange 15 and a second connecting flange 23. This improves the overall steering performance of the bogie body 1 and reduces wear on the guide wheels 8 when they curve along the sides of the track beam. The airtight cavity 20 inside the body 17 and the damper 24 installed at the bottom of the connecting end block 18 are constructed using existing technology piston rods and shock-absorbing springs. When the straddle-type vehicle bogie generates centripetal force while traveling at high speed on the track beam, the first support component 5 can move downward at the bottom of the bogie body 1 under the elastic force of the damper 24. This allows the guide wheel 8 installed on the first support component 5 to always be in a guiding fit with the sides of the track beam when passing through curves on both sides of the track beam, thereby ensuring the stability of the train at high speed.
[0057] This solution involves adding a first transmission assembly 9 to each of the four corners of the bogie body 1. The first transmission assembly 9 consists of a second bearing seat 14, a first connecting flange 15, and a transmission gear disk 16. When the straddle-type vehicle bogie travels through a curve on the track beam, the guide wheels 8 added to the bottom of both sides of the bogie body 1 will swing adaptively along the curvature of both sides of the track beam. Through the second frame 30 and the third frame 31 added to both sides of the drive assembly 2, the guide wheels 8 in the swinging state can also drive the drive assembly 2 and the travel wheel assembly 3 hinged at the top of the bogie body 1 to swing synchronously, so that the travel path of the travel wheel assembly 3 can perfectly fit the curvature of the track beam, thereby reducing the wear and other problems of the travel wheels when going through curves on the track beam.
[0058] This solution involves adding a second transmission assembly 10 to each of the four corners of the top of the bogie body 1. The second transmission assembly 10 consists of a first cover 26, a sealing plate 27, a slide rail 28, and a transmission gear plate 29. When the guide wheel 8 passes through a curve on both sides of the track beam, the guide wheel 8, which swings through the curve, can drive the transmission gear disk 16 to rotate synchronously because the first connecting flange 15 and the second connecting flange 23 are fixedly connected. Through the meshing connection between the transmission gear plate 29 and the transmission gear disk 16, the transmission gear plate 29 can slide to the left or right inside the first cover 26. When the guide wheel 8 changes from passing through a curve on both sides of the track beam to traveling in a straight line, the first compression spring 35 added to both ends of the transmission gear plate 29 can reset the swinging guide wheel 8, so that the guide wheel 8 can maintain a guiding and close contact with both sides of the track beam when traveling through a curve or traveling in a straight line.
[0059] This solution uses microcontrollers 40 installed on both sides of the top of the first cover 26. Each microcontroller 40 consists of a second cover 41, a guide adjustment groove 42, an adjustment push block 43, a second compression spring 44, and a contact switch 45. When the guide wheel 8 causes the transmission tooth plate 29 to slide to the left or right inside the first cover 26 due to bending, it can drive the pusher 37 installed on the top of the transmission tooth plate 29 to move synchronously. When the pusher 37 moves to the left or right and presses against the contact switch 45, it can trigger the generation of an electrical signal through the contact switch 45. The electrical signal can be used to monitor and record the real-time operation of the guide wheel 8. At the same time, the operation of the straddle-type vehicle bogie on the track beam can be inferred and judged based on the monitored and recorded electrical signal data, thereby improving the safety of train operation.
[0060] This scheme uses the pusher 37 to move left or right to press the contact switch 45. Since the contact switch 45 is electrically connected to the electric push rod 7 and the electric control valve 22, the contact switch 45 can also control the electric push rod 7 and the electric control valve 22. When the electric push rod 7 and the electric control valve 22 receive a touch signal, the electric push rod 7, under energized operation, can make a slight downward adjustment to the guide wheel 8 in the cornering state. The downward adjustment of the guide wheel 8 can ensure that the guide wheel 8 maintains a guiding contact with both sides of the track beam when cornering. Under energized operation, the electric control valve 22 will open, and air can normally enter the airtight cavity 20 in the sealed state. The damper 24 installed at the bottom of the connecting end block 18 can adjust the centrifugal force according to the direction of rotation. The force adjusts the position of the guide wheel 8. Similarly, when the electric push rod 7 and the electric control air valve 22 cannot receive the touch signal, the electric push rod 7, under power operation, can retract and reset the guide wheel 8 in the bending state. The reset and adjusted guide wheel 8 can ensure that the guide wheel 8 maintains a guiding fit with both sides of the track beam when traveling in a straight line. Under power operation, the electric control air valve 22 will be closed, and since the outside air cannot enter normally, the airtight cavity 20 will return to a sealed state. The airtight cavity 20 in a sealed state can reduce the extension and contraction of the damper 24. Through the cooperation of the damping plate 6 and the damping rod 32, it can effectively prevent the guide wheel 8 from moving up and down due to its own vibration when traveling in a straight line.
