In addition, the present application provides examples of various specific processes and materials, but one of ordinary skill in the art will recognize the application of other processes and/or the use of other materials.

The application is described below with reference to specific embodiments in conjunction with the accompanying drawings:

In the related art, the container is widely applied in the freight fields of ports, logistics, coal and the like, but in actual transportation, the container is often limited by objective factors such as far distance of railway stations, complex surrounding environment of partial areas and the like, and the container can only be transported through a large number of collecting cards, so that the problems of congestion, pollution, efficiency, safety and the like are outstanding. The freight system adopting air rail transportation can solve the problems of congestion, pollution, efficiency, safety and the like existing in the transportation of the collection cards to a certain extent, is widely focused on the market, and has good market prospect. However, in the overhead rail car, the wheel sets are fixedly arranged in the bogie, so that the guidance quality is poor, and the running stability of the overhead rail car and the service life of the bogie are affected.

Aiming at the problem of poor steering performance of a wheel set fixedly arranged in an aerial railway car, the embodiment of the application provides a bogie, as shown in fig. 1 to 14, which comprises a framework component 100, a wheel set component 200 and a forced guiding component 300, wherein the extending direction X of the framework component is the same as the extending direction of an aerial railway beam 1000; the wheel set assembly 200 comprises a first wheel set 210 and a second wheel set 220, the first wheel set 210 and the second wheel set 220 are arranged at intervals along the extending direction of the aerial track beam 1000, and the first wheel set 210 and the second wheel set 220 are movably connected with the framework assembly 100; the forced guiding assembly 300 is provided at least at one side of the frame assembly 100, and the forced guiding assembly 300 is connected between the first wheel set 210 and the second wheel set 220 to adjust a distance between portions of the first wheel set 210 and the second wheel set 220 on the same side as the forced guiding assembly 300.

As shown in fig. 1 to 5, in the bogie provided by the embodiment of the present application, the forced guiding component 300 is at least disposed on one 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, so as to adjust the distance between the parts of the first wheel set 210 and the second wheel set 220 on the same side as the forced guiding component 300, where the first wheel set 210 and the second wheel set 220 can respectively generate a certain deflection 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 two sides of the frame component 100 is changed to adapt to the bending moment of the air rail beam 1000, and the guiding capability of the wheel set component 200 can be improved, thereby improving the stability and safety of the running of the air rail car; meanwhile, the abrasion of the wheels 2111 and the track can be reduced, the torsion impact on the bogie is reduced, and the service lives of the wheels 2111 and the bogie are prolonged.

In the embodiment of the present application, as shown in fig. 1 to 5, the extending direction X of the frame assembly is the same as the extending direction of the air rail beam 1000, the width direction Y of the frame assembly is perpendicular to the extending direction of the air rail beam 1000, and the extending direction X of the frame assembly and the width direction Y of the frame assembly are perpendicular to the gravitational direction Z, respectively. The two ends of the frame assembly 100 in the extending direction X of the frame assembly may be defined as a front end and a rear end of the frame assembly 100, respectively, and the two sides of the frame assembly 100 in the width direction Y of the frame assembly may be defined as a left side and a right side of the frame assembly 100, respectively.

In some embodiments, the first wheel set 210 and the second wheel set 220 are both movably connected to the frame assembly 100 such that the first wheel set 210 and the second wheel set 220 can swing a certain angle or move a certain range relative to the frame assembly 100 at least in the extending direction X of the frame assembly, thereby enabling adjustment of the distance between the first wheel set 210 and the second wheel set 220 at the left and/or right side portions of the frame assembly 100.

In some embodiments, the forced guiding assembly 300 may be disposed on either side of the frame assembly in the width direction Y.

For example, the forced guiding assembly 300 is disposed at the left side of the frame assembly 100, and the forced guiding assembly 300 is connected between the first wheel set 210 and the second wheel set 220 at the left side of the frame assembly 100, and the forced guiding assembly 300 can adjust the distance between the first wheel set 210 and the portion of the second wheel set 220 at the left side of the frame assembly 100. When the air rail beam 1000 turns left, the forced guiding assembly 300 can reduce the distance between the first wheel pair 210 and the second wheel pair 220 at the left side of the framework assembly 100, so that the distance between the first wheel pair 210 and the second wheel pair 220 at the left side of the framework assembly 100 is reduced, correspondingly, the distance between the first wheel pair 210 and the second wheel pair 220 at the right side of the framework assembly 100 is increased, so that the distance between the first wheel pair 210 and the second wheel pair 220 at the right side of the framework assembly 100 is increased, and the bogie is forced to be guided to the left side by the forced guiding assembly 300, so that the left turning bending moment of the air rail beam 1000 is adapted, the abrasion between the wheels 2111 and the air rail beam 1000 is reduced, the bending stress of the bogie is reduced to a certain extent when turning left, and the service lives of the wheels 2111, the air rail beam 1000 and the bogie can be prolonged; meanwhile, the steering capability of the bogie is improved when the bogie runs left on the aerial track beam 1000, and the aerial track car with the bogie is better in running stability and safety. When the air track beam 1000 turns right, the forced guiding component 300 can increase the distance between the first wheel pair 210 and the second wheel pair 220 at the left side of the framework component 100, and correspondingly, the distance between the first wheel pair 210 and the second wheel pair 220 at the right side of the framework component 100 is reduced, so that the bogie is forced to guide to the right side through the forced guiding component 300 to adapt to the right turning bending moment of the air track beam 1000, the abrasion of the wheels 2111 and the air track beam 1000 is reduced, the bending stress of the bogie during right turning is reduced to a certain extent, and the service lives of the wheels 2111, the air track beam 1000 and the bogie can be prolonged; meanwhile, the steering capability of the bogie is improved when the bogie runs on the aerial track beam 1000 in a right-turning mode, and the aerial track car with the bogie is better in running stability and safety.

As another example, the forced guiding assembly 300 is disposed on the right side of the frame assembly 100, and the forced guiding assembly 300 is connected between the first wheel set 210 and the second wheel set 220 on the right side of the frame assembly 100, and the forced guiding assembly 300 can adjust the distance between the first wheel set 210 and the portion of the second wheel set 220 on the right side of the frame assembly 100. When the air rail beam 1000 turns right, the forced guiding assembly 300 may reduce the distance between the first wheel set 210 and the portion of the second wheel set 220 on the right side of the frame assembly 100 to reduce the distance between the wheels 2111 of the first wheel set 210 and the second wheel set 220 on the right side of the frame assembly 100, and correspondingly, increase the distance between the first wheel set 210 and the portion of the second wheel set 220 on the left side of the frame assembly 100 to increase the distance between the wheels 2111 of the first wheel set 210 and the second wheel set 220 on the left side of the frame assembly 100 to force the bogie to be guided to the right side by the forced guiding assembly 300 to accommodate the right turning bending moment of the air rail beam 1000. The forced guiding assembly 300 may increase the distance between the first wheel set 210 and the second wheel set 220 at the right side of the frame assembly 100 when the air rail beam 1000 turns left, and correspondingly decrease the distance between the first wheel set 210 and the second wheel set 220 at the left side of the frame assembly 100, thereby forcing the bogie to guide to the left side by the forced guiding assembly 300 to accommodate the left turning bending moment of the air rail beam 1000.

As an alternative embodiment, the forced guiding assembly 300 is provided on both sides of the frame assembly 100.

In some embodiments, as shown in fig. 1 to 5, the forced guiding members 300 may be provided at opposite sides of the frame member in the width direction Y, respectively, that is, at left and right sides of the frame member 100, respectively, the forced guiding members 300 are provided. The forced guiding assembly 300 provided at the left side of the frame assembly 100 is connected between the first wheel set 210 and the portion of the second wheel set 220 located at the left side of the frame assembly 100, and the distance between the first wheel set 210 and the portion of the second wheel set 220 located at the left side of the frame assembly 100 can be adjusted; meanwhile, the forced guiding assembly 300 provided at the right side of the frame assembly 100 is connected between the first wheel set 210 and the portion of the second wheel set 220 located at the right side of the frame assembly 100, and the distance between the first wheel set 210 and the portion of the second wheel set 220 located at the right side of the frame assembly 100 can be adjusted. When the air rail beam 1000 turns left, the forced guiding assembly 300 at the left side of the frame assembly 100 can reduce the distance between the first wheel set 210 and the second wheel set 220 at the left side of the frame assembly 100, so that the distance between the wheels 2111 at the left side of the frame assembly 100 of the first wheel set 210 and the second wheel set 220 is reduced; at the same time, the forced guiding assembly 300 on the right side of the frame assembly 100 may increase the distance between the first wheel set 210 and the second wheel set 220 on the right side of the frame assembly 100 to increase the distance between the wheels 2111 on the right side of the frame assembly 100 in the first wheel set 210 and the second wheel set 220, thereby simultaneously adjusting the distance between the wheels 2111 on the left side of the frame assembly 100 and the spacing between the wheels 2111 on the right side of the frame assembly 100 by the forced guiding assembly 300 to force the wheels 2111 of the bogie to guide to the left side to accommodate the left turning bending moment of the air rail beam 1000. The forced guiding assembly 300 at the left side of the frame assembly 100 may increase the distance between the first wheel set 210 and the portion of the second wheel set 220 at the left side of the frame assembly 100 when the air rail beam 1000 turns right, such that the wheels 2111 at the left side of the frame assembly 100 of the first wheel set 210 and the second wheel set 220 are increased in distance; meanwhile, the forced guiding assembly 300 on the right side of the frame assembly 100 may reduce the distance between the first wheel set 210 and the second wheel set 220 on the right side of the frame assembly 100 to reduce the distance between the wheels 2111 on the right side of the frame assembly 100 in the first wheel set 210 and the second wheel set 220, 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 are simultaneously adjusted by the forced guiding assembly 300 to force the wheels 2111 of the bogie to guide to the right side to adapt to the right turning bending moment of the air rail beam 1000.

In some embodiments, as shown in fig. 7 and 8, the frame assembly 100 includes a frame body 110, the frame body 110 including two side beams 111 disposed opposite to each other, two end beams 113 connected between ends of the two side beams 111, respectively, and a cross beam 112 connected between the two side beams 111. Two side beams 111 are respectively located at left and rear sides of the frame assembly 100, two end beams 113 are respectively located at front and rear ends of the frame assembly 100, and a cross beam 112 is located at a middle portion of the frame assembly 100.

As an alternative embodiment, forced guiding assembly 300 includes any one of a telescoping mechanism, a linkage mechanism 310, and a linear displacement drive mechanism.

In some embodiments, the forced guiding assembly 300 may be configured by different mechanisms to drive the first wheel set 210 and the second wheel set 220 to oscillate or move relative to the frame assembly 100.

For example, the forced guiding assembly 300 may include a telescopic mechanism, which may be a hydraulic cylinder, a pneumatic cylinder, or the like, and the fixed end and the telescopic end of the telescopic mechanism may be connected to portions of the first wheel set 210 and the second wheel set 220 located on the same side of the frame assembly 100, respectively, and the first wheel set 210 and the second wheel set 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 left side and/or the right side portions of the frame assembly 100 and the first wheel set 210 and the second wheel set 220, thereby adjusting the distance between the left side wheels 2111 and the right side wheels 2111 of the frame assembly 100, so as to force the wheels 2111 of the bogie to guide along with the bending moment change of the overhead rail beam 1000. As another example, the forced guiding assembly 300 may include a link mechanism 310, where the link mechanism 310 is connected to a portion of the first wheel set 210 and the second wheel set 220 located on the same side of the frame assembly 100, and deformation of the link mechanism 310 is used to drive the first wheel set 210 and the second wheel set 220 to swing or move relative to the frame assembly 100, so as to adjust a distance between portions of the first wheel set 210 and the second wheel set 220 located on the same side of the frame assembly 100, and further adjust a distance between wheels 2111 on the left side of the frame assembly 100 and a distance between wheels 2111 on the right side, so as to force the wheels 2111 of the bogie to guide along with a change in bending moment of the aerial rail beam 1000.

For another example, the forced guiding assembly 300 may include a linear displacement driving mechanism, which may be a ball screw, a sliding screw, or the like, and the screw and the nut of the screw may be connected to the portions of the first wheel set 210 and the second wheel set 220 located on the same side of the frame assembly 100, respectively, and the screw is driven by a motor to rotate relative to the nut, so that the first wheel set 210 and the second wheel set 220 may be driven to swing or move relative to the frame assembly 100, so as to adjust the distance between the first wheel set 210 and the second wheel set 220 on the left side and/or the right side of the frame assembly 100, and further adjust the distance between the wheels 2111 on the left side and the wheels 2111 on the right side of the frame assembly 100, so as to force the wheels 2111 of the bogie to guide along with the bending moment change of the aerial track beam 1000.

As an alternative embodiment, forced guiding assembly 300 includes a linkage 310 and a connecting rod 320 connected to linkage 310, connecting rod 320 being used to connect with the body or frame of an overhead railcar to drive the deformation of linkage 310.

In some embodiments, as shown in fig. 1-6, the forced guiding assembly 300 includes a linkage 310 and a connecting rod 320, the connecting rod 320 being connected between the linkage 310 and a body or frame of the overhead rail car. When the aerial railcar passes through the curved aerial rail beam 1000, the body and the frame of the aerial railcar deflect, the connecting pull rod 320 can be driven to move in the extending direction X of the framework component through the deflection of the body or the frame, and then the connecting pull rod 320 drives the link mechanism 310 to deform, so that the distance between the first wheel pair 210 and the second wheel pair 220 at the left side and/or the right side of the framework component 100 is adjusted, and finally the distance between the wheels 2111 at the left side and the wheel 2111 at the right side of the framework component 100 are adjusted, so that the wheels 2111 of the bogie are forced to guide along with the bending moment change of the aerial rail beam 1000. That is, the link mechanism 310 can be driven to deform by the self-component part of the overhead railcar, so that the automatic steering of the bogie is realized, and an independent driving source is not required to be arranged, thereby simplifying the structure of the forced steering component 300 and reducing the manufacturing cost of the forced steering component 300.

As an alternative embodiment, as shown in fig. 4 and 6, the linkage 310 includes a forced guiding lever 311, a first forced guiding connection 312, and a second forced guiding connection 313.
