DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0042] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials; however, those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0043] This application is described below with reference to the accompanying drawings and specific embodiments:

[0044] In the transportation sector, the development level of multimodal transport remains low, with road transport remaining the dominant mode of transport for a long time. The coordination and connection between road, rail, and water transport is not smooth, and multimodal transport suffers from problems such as an imperfect market environment, inadequate regulations and standards, and lagging application of advanced technologies. Among related technologies, containers are widely used in port, logistics, and coal freight, but in actual transport, they are often constrained by objective factors such as the distance of railway stations and the complex surrounding environment in some areas, often requiring extensive truck transshipment, leading to significant problems such as congestion, pollution, inefficiency, and safety. Elevated rail freight systems can, to some extent, solve the problems of congestion, pollution, efficiency, and safety associated with truck transshipment, attracting widespread market attention and possessing good market prospects. However, in elevated rail vehicles, the wheelsets are fixed in the bogies, resulting in poor guidance and affecting the stability of the elevated rail vehicle and the service life of the bogies.

[0045] To address the problem of poor guiding performance of fixed wheelsets in aerial rail vehicles, this application provides a bogie, such as... Figures 1 to 14 As shown, the bogie includes a frame assembly 100, a wheelset assembly 200, and a guide assembly 300. The extension direction X of the frame assembly is the same as the extension direction of the overhead track beam 1000. The wheelset assembly 200 includes a first wheelset 210 and a second wheelset 220, which are spaced apart along the extension direction of the overhead track beam 1000. Both the first wheelset 210 and the second wheelset 220 are movably connected to the frame assembly 100. The guide assembly 300 is at least located on one side of the frame assembly 100 and is connected between the first wheelset 210 and the second wheelset 220 to adjust the distance between the portions of the first wheelset 210 and the second wheelset 220 that are on the same side as the guide assembly 300.

[0046] The bogie provided in the embodiments of this application, such as Figures 1 to 5As shown, the forced guiding component 300 is arranged at least on one side of the frame component 100, and is connected between the first wheel set 210 and the second wheel set 220 to adjust the distance between the parts of the first wheel set 210 and the second wheel set 220 on the same side of the forced guiding component 300. The first wheel set 210 and the second wheel set 220 can be deflected relative to the frame component 100 under the action of the forced guiding component 300, so that the distance between the parts of the first wheel set 210 and the second wheel set 220 on both sides of the frame component 100 changes to adapt to the bending moment of the air track beam 1000, which can improve the guiding ability of the wheel set component 200, and further improve the stability and safety of the air track vehicle. At the same time, the wear of the wheels 2111 and the track can be reduced, the torsional impact on the bogie can be reduced, and the service life of the wheels 2111 and the bogie can be prolonged.

[0047] In the embodiments of the present application, as shown in Figures 1 to 5 The extension direction X of the frame component is the same as the extension direction of the air track beam 1000, the width direction Y of the frame component is perpendicular to the extension direction of the air track beam 1000, and the extension direction X of the frame component and the width direction Y of the frame component are both perpendicular to the gravity direction Z. The two ends of the frame component 100 in the extension direction X of the frame component can be defined as the front end and the rear end of the frame component 100, and the two sides of the frame component 100 in the width direction Y of the frame component can be defined as the left side and the right side of the frame component 100.

[0048] In some embodiments, the first wheel set 210 and the second wheel set 220 are movably connected with the frame component 100, so that the first wheel set 210 and the second wheel set 220 can swing by a certain angle or move within a certain range relative to the frame component 100 at least in the extension direction X of the frame component, so as to adjust the distance between the parts of the first wheel set 210 and the second wheel set 220 on the left side and / or the right side of the frame component 100.

[0049] In some embodiments, the forced guiding component 300 can be arranged on any one side of the width direction Y of the frame component.

[0050] For example, the forced guiding component 300 is arranged at the left side of the frame component 100, and the forced guiding component 300 is connected between the first wheel set 210 and the second wheel set 220 at the left side of the frame component 100, and the forced guiding component 300 can adjust the distance between the first wheel set 210 and the second wheel set 220 at the left side of the frame component 100. When the aerial track beam 1000 turns left, the forced guiding component 300 can reduce the distance between the first wheel set 210 and the second wheel set 220 at the left side of the frame component 100, so as to reduce the distance between the wheels 2111 of the first wheel set 210 and the second wheel set 220 at the left side of the frame component 100, and correspondingly, increase the distance between the first wheel set 210 and the second wheel set 220 at the right side of the frame component 100, so as to increase the distance between the wheels 2111 of the first wheel set 210 and the second wheel set 220 at the right side of the frame component 100, thereby forcing the bogie to guide to the left side through the forced guiding component 300 to adapt to the left turning moment of the aerial track beam 1000, reduce the wear of the wheels 2111 and the aerial track beam 1000, and reduce the bending stress of the bogie to a certain extent when the bogie turns left, thereby prolonging the service life of the wheels 2111, the aerial track beam 1000 and the bogie; meanwhile, the guiding ability of the bogie when driving on the aerial track beam 1000 is improved, and the stability and safety of the aerial track vehicle with the bogie are better. When the aerial track beam 1000 turns right, the forced guiding component 300 can increase the distance between the first wheel set 210 and the second wheel set 220 at the left side of the frame component 100, and correspondingly, reduce the distance between the first wheel set 210 and the second wheel set 220 at the right side of the frame component 100, thereby forcing the bogie to guide to the right side through the forced guiding component 300 to adapt to the right turning moment of the aerial track beam 1000, reduce the wear of the wheels 2111 and the aerial track beam 1000, and reduce the bending stress of the bogie to a certain extent when the bogie turns right, thereby prolonging the service life of the wheels 2111, the aerial track beam 1000 and the bogie; meanwhile, the guiding ability of the bogie when driving on the aerial track beam 1000 is improved, and the stability and safety of the aerial track vehicle with the bogie are better.

[0051] For example, the force guiding component 300 is arranged on the right side of the frame component 100, and the force guiding component 300 is connected between the first wheel set 210 and the second wheel set 220 on the right side of the frame component 100. The force guiding component 300 can adjust the distance between the first wheel set 210 and the second wheel set 220 on the right side of the frame component 100. When the air track beam 1000 turns right, the force guiding component 300 can reduce the distance between the first wheel set 210 and the second wheel set 220 on the right side of the frame component 100, so as to reduce the distance between the wheels 2111 on the right side of the frame component 100 in the first wheel set 210 and the second wheel set 220, and correspondingly increase the distance between the first wheel set 210 and the second wheel set 220 on the left side of the frame component 100, so as to increase the distance between the wheels 2111 on the left side of the frame component 100 in the first wheel set 210 and the second wheel set 220, thereby forcing the bogie to guide to the right side through the force guiding component 300 to adapt to the right turning moment of the air track beam 1000. When the air track beam 1000 turns left, the force guiding component 300 can increase the distance between the first wheel set 210 and the second wheel set 220 on the right side of the frame component 100, and correspondingly reduce the distance between the first wheel set 210 and the second wheel set 220 on the left side of the frame component 100, thereby forcing the bogie to guide to the left side through the force guiding component 300 to adapt to the left turning moment of the air track beam 1000.

[0052] As an optional embodiment, the force guiding component 300 is arranged on both sides of the frame component 100.

[0053] In some embodiments, as Figures 1 to 5As shown, the force guiding component 300 can be arranged on opposite sides of the width direction Y of the bogie assembly, that is, the force guiding component 300 is arranged on the left side and the right side of the bogie assembly 100. The force guiding component 300 arranged on the left side of the bogie assembly 100 is connected between the first wheel set 210 and the part of the second wheel set 220 located on the left side of the bogie assembly 100, and can adjust the distance between the first wheel set 210 and the part of the second wheel set 220 located on the left side of the bogie assembly 100. At the same time, the force guiding component 300 arranged on the right side of the bogie assembly 100 is connected between the first wheel set 210 and the part of the second wheel set 220 located on the right side of the bogie assembly 100, and can adjust the distance between the first wheel set 210 and the part of the second wheel set 220 located on the right side of the bogie assembly 100. When the air track beam 1000 turns left, the force guiding component 300 on the left side of the bogie assembly 100 can reduce the distance between the first wheel set 210 and the part of the second wheel set 220 located on the left side of the bogie assembly 100, so as to reduce the distance between the wheels 2111 of the first wheel set 210 and the second wheel set 220 located on the left side of the bogie assembly 100. At the same time, the force guiding component 300 on the right side of the bogie assembly 100 can increase the distance between the first wheel set 210 and the part of the second wheel set 220 located on the right side of the bogie assembly 100, so as to increase the distance between the wheels 2111 of the first wheel set 210 and the second wheel set 220 located on the right side of the bogie assembly 100. Thus, the force guiding component 300 adjusts the distance between the wheels 2111 on the left side and the right side of the bogie assembly 100 at the same time, and forces the wheels 2111 of the bogie to guide to the left, so as to adapt to the left turning moment of the air track beam 1000. When the air track beam 1000 turns right, the force guiding component 300 on the left side of the bogie assembly 100 can increase the distance between the first wheel set 210 and the part of the second wheel set 220 located on the left side of the bogie assembly 100, so as to increase the distance between the wheels 2111 of the first wheel set 210 and the second wheel set 220 located on the left side of the bogie assembly 100. At the same time, the force guiding component 300 on the right side of the bogie assembly 100 can reduce the distance between the first wheel set 210 and the part of the second wheel set 220 located on the right side of the bogie assembly 100, so as to reduce the distance between the wheels 2111 of the first wheel set 210 and the second wheel set 220 located on the right side of the bogie assembly 100. Thus, the force guiding component 300 adjusts the distance between the wheels 2111 on the left side and the right side of the bogie assembly 100 at the same time, and forces the wheels 2111 of the bogie to guide to the right, so as to adapt to the right turning moment of the air track beam 1000.

[0054] In some embodiments, as Figure 7 and Figure 8As shown, the frame assembly 100 comprises a frame body 110, which comprises two side beams 111 arranged oppositely, two end beams 113 respectively connected between the end portions of the two side beams 111, and a cross beam 112 connected between the two side beams 111. The two side beams 111 are respectively located at the left side and the rear side of the frame assembly 100, the two end beams 113 are respectively located at the front end and the rear end of the frame assembly 100, and the cross beam 112 is located at the middle of the frame assembly 100.

[0055] As an optional embodiment, the forced guiding assembly 300 comprises any one of a telescopic mechanism, a connecting rod mechanism 310, and a linear displacement driving mechanism.

[0056] In some embodiments, the forced guiding assembly 300 can drive the first wheel pair 210 and the second wheel pair 220 to swing or move relative to the frame assembly 100 through different mechanisms.

[0057] For example, the forced guiding assembly 300 can comprise a telescopic mechanism, which can be a hydraulic cylinder, a pneumatic cylinder, or the like. The fixed end and the telescopic end of the telescopic mechanism can be respectively connected with the portions of the first wheel pair 210 and the second wheel pair 220 located at the same side of the frame assembly 100. The first wheel pair 210 and the second wheel pair 220 are driven to swing or move relative to the frame assembly 100 through the telescopic mechanism, so as to adjust the distance between the first wheel pair 210 and the second wheel pair 220 at the same side of the frame assembly 100, and further adjust the distance between the wheels 2111 at the left side and the distance between the wheels 2111 at the right side of the frame assembly 100, so as to force the wheels 2111 of the bogie to guide according to the bending moment change of the air track beam 1000. For another example, the forced guiding assembly 300 can comprise a connecting rod mechanism 310, which is connected with the portions of the first wheel pair 210 and the second wheel pair 220 located at the same side of the frame assembly 100. The first wheel pair 210 and the second wheel pair 220 are driven to swing or move relative to the frame assembly 100 through the deformation of the connecting rod mechanism 310, so as to adjust the distance between the first wheel pair 210 and the second wheel pair 220 at the same side of the frame assembly 100, and further adjust the distance between the wheels 2111 at the left side and the distance between the wheels 2111 at the right side of the frame assembly 100, so as to force the wheels 2111 of the bogie to guide according to the bending moment change of the air track beam 1000.

[0058] For example, the forced guiding component 300 can include a linear displacement driving mechanism, which can be a ball screw, a sliding screw, or the like. The screw rod and the screw nut of the screw can be connected to the portions of the first wheel pair 210 and the second wheel pair 220 on the same side of the frame component 100, respectively. The screw rod can be driven to rotate relative to the screw nut by a motor, so as to drive the first wheel pair 210 and the second wheel pair 220 to swing or move relative to the frame component 100, so as to adjust the distance between the first wheel pair 210 and the second wheel pair 220 on the left side and / or the right side of the frame component 100, and further adjust the distance between the wheels 2111 on the left side and the distance between the wheels 2111 on the right side of the frame component 100, so as to force the wheels 2111 of the bogie to guide according to the change of the bending moment of the air track beam 1000.

[0059] As an optional embodiment, the forced guiding component 300 includes a connecting rod mechanism 310 and a connecting pull rod 320 connected to the connecting rod mechanism 310. The connecting pull rod 320 is used to be connected to the vehicle body or the vehicle frame of the air track vehicle, so as to drive the connecting rod mechanism 310 to deform.

[0060] In some embodiments, as shown in Figures 1 to 6 The forced guiding component 300 includes the connecting rod mechanism 310 and the connecting pull rod 320 connected between the connecting rod mechanism 310 and the vehicle body or the vehicle frame of the air track vehicle. When the air track vehicle passes through the curved air track beam 1000, the vehicle body and the vehicle frame of the air track vehicle will be deflected. The deflection of the vehicle body or the vehicle frame can drive the connecting pull rod 320 to move in the extension direction X of the frame component, and further drive the connecting rod mechanism 310 to deform through the connecting pull rod 320, so as to adjust the distance between the first wheel pair 210 and the second wheel pair 220 on the left side and / or the right side of the frame component 100, and finally adjust the distance between the wheels 2111 on the left side and the distance between the wheels 2111 on the right side of the frame component 100, so as to force the wheels 2111 of the bogie to guide according to the change of the bending moment of the air track beam 1000. That is, the connecting rod mechanism 310 can be driven to deform through the self-component of the air track vehicle, so as to realize the automatic guiding of the bogie without setting an independent driving source, so as to simplify the structure of the forced guiding component 300 and reduce the manufacturing cost of the forced guiding component 300.

[0061] As an optional embodiment, as shown in Figure 4 and Figure 6As shown, the connecting rod mechanism 310 comprises a guide lever 311, a first guide connecting piece 312, and a second guide connecting piece 313. The guide lever 311 is sequentially provided with a first hinged hole 3111, a lever hinged hole 3112, a second hinged hole 3113, and a pull rod hinged hole 3114 along the extension direction of the guide lever 311. The guide lever 311 is hinged with the frame assembly 100 through the lever hinged hole 3112, and is hinged with the connecting pull rod 320 through the pull rod hinged hole 3114. The first end of the first guide connecting piece 312 is hinged with the guide lever 311 through the first hinged hole 3111, and the second end of the first guide connecting piece 312 is connected with the first wheel set 210. The first end of the second guide connecting piece 313 is hinged with the guide lever 311 through the second hinged hole 3113, and the second end of the second guide connecting piece 313 is connected with the second wheel set 220.

[0062] In some embodiments, opposite sides of the frame body 110 in the width direction Y of the frame assembly can be respectively provided with guide lever seats 116. As shown in Figure 7 and Figure 8 As shown, the guide lever seats 116 can be respectively arranged on the two side beams 111, so that the guide lever seats 116 are respectively located on the left side and the right side of the frame assembly 100.

[0063] In some embodiments, as shown in Figure 6 and Figure 7 The guide lever 311 is hinged with the guide lever seat 116 through the lever hinged hole 3112, so that the guide lever 311 can rotate around the guide lever seat 116. The first hinged hole 3111 and the second hinged hole 3113 are respectively arranged on the two sides of the lever hinged hole 3112 of the guide lever 311. The guide lever 311 is hinged with the first end of the first guide connecting piece 312 through the first hinged hole 3111, and is hinged with the first end of the second guide connecting piece 313 through the second hinged hole 3113. The pull rod hinged hole 3114 is also arranged on the guide lever 311, and the guide lever 311 is hinged with the connecting pull rod 320 through the pull rod hinged hole 3114. When the vehicle body or the frame of the aerial track vehicle moves relative to any side (left side and / or right side) of the frame assembly 100 in the extension direction X of the frame assembly, the connecting pull rod 320 will pull the guide lever 311, so that the guide lever 311 rotates around the guide lever seat 116, and the guide lever 311 drives the first guide connecting piece 312 and the second guide connecting piece 313 to move. The overall structure of the connecting rod mechanism 310 is simple, and no additional driving source is needed, so that the self-guiding of the bogie can be realized by the aerial track vehicle itself.

[0064] For example, when the aerial track beam 1000 turns left, the car body and frame of the aerial track vehicle deflects left. The car body or frame will drive the connecting pull rod 320 on the left side of the frame assembly 100 to move towards the rear end of the frame assembly 100, so that the forced guiding lever 311 on the left side of the frame assembly 100 rotates counterclockwise around the forced guiding lever seat 116, and the first forced guiding connecting piece 312 and the second forced guiding connecting piece 313 move towards each other, so that the distance between the first wheel set 210 and the second wheel set 220 on the left side of the frame assembly 100 decreases, and the distance between the wheels 2111 on the left side of the frame assembly 100 decreases; at the same time, the car body or frame will drive the connecting pull rod 320 on the right side of the frame assembly 100 to move towards the front end of the frame assembly 100, so that the forced guiding lever 311 on the right side of the frame assembly 100 rotates clockwise around the forced guiding lever seat 116, and the first forced guiding connecting piece 312 and the second forced guiding connecting piece 313 move away from each other, so that the distance between the first wheel set 210 and the second wheel set 220 on the right side of the frame assembly 100 increases, and the distance between the wheels 2111 on the right side of the frame assembly 100 increases, so that the distance between the wheels 2111 on the left side of the frame assembly 100 and the distance between the wheels 2111 on the right side of the frame assembly 100 adapt to the bending moment of the left turn of the aerial track beam 1000, realize the self-guiding ability of the bogie, and increase the passing performance of the left turn curve of the bogie.

[0065] As an optional embodiment, as shown in FIG. 6, the forced guiding lever 311 is provided with a forced guiding lever seat 116, and the forced guiding lever seat 116 is provided with a forced guiding connecting piece 312 and a forced guiding connecting piece 313.

[0097] In related technologies, suspended aerial rail systems, whether for passenger or freight transport, generally use open-beam track beams. However, open-beam track beams have poor vertical rigidity, leading to higher track costs for longer lines. Compared to open-beam track beams, fully enclosed track beams, comprising box girders and tracks positioned on opposite sides of the box girders, use less steel and are more economical. To adapt the bogie of this application to fully enclosed track beams, such as...

[0098] In the embodiment of the present application, the bogie forms a "car-pack-rail" running mechanism mode by extending the first branch arm 211 and the second branch arm 221 to opposite sides of the air track beam 1000 respectively, which can adapt to the full-enclosed track beam. Since the full-enclosed track beam uses less steel beam, the manufacturing cost of the air track beam 1000 can be reduced, better economic efficiency is achieved, and the risk of derailment of the bogie can be effectively reduced, and the safety performance of the air track car is improved.

From the market situation, the air track transportation has the application demand of large volume, high frequency, long distance and large slope. The maintenance cost of the solid rubber wheels or pneumatic tires is too high, which is difficult to be accepted by the market.

[0111] In some embodiments, as shown in Figure 11 and Figure 10 , by arranging the top rail brake assembly 700 on the wheel set assembly 200 and / or the frame assembly 100, the top rail brake 710 in the positioning brake assembly is lifted relative to the wheel set assembly 200 and / or the frame assembly 100 when braking is needed, so as to abut against the brake rail 1200 of the air track beam 1000, thereby providing a non-stick braking force for the bogie, further increasing the braking force of the bogie, so that the bogie meets the parking demand of the vehicle under the conditions of strong wind and large slope, improves the safety of the bogie, and expands the use range of the bogie.

[0119] In the embodiments of the present application, the aerial rail beam 1000 adopts the box beam 1300 structure, and the box beam 1300 uses less steel beams, which can reduce the construction cost of the aerial rail system. As an optional embodiment, the aerial rail beam 1000 further comprises a brake rail 1200 arranged at the bottom of the box beam 1300.

[0120] In some embodiments, the brake rail 1200 at the bottom of the box beam 1300 is used to act with the top rail brake 710 in the bogie to provide a non-stick braking force for the bogie, so as to increase the braking force of the bogie, so that the bogie meets the parking requirements of the vehicle under the conditions of strong wind and large slope, improves the safety of the bogie, and expands the use range of the bogie.
