The support plate 00111 is used to carry the running wheels 50 such that the running wheels 50 move over the support plate 00111 and the switch wheels 80 are used to move between the switch rails 0013 and the inner side plates 00113. The support plate 00111 at the bifurcation section 002 is connected with a transition plate 00114, the transition plate 00114 is flush with the support plate 00111, and the transition plate 00114 extends in a direction away from the outer side plate 00112 to the inner side plate 00113, the transition plate 00114 being configured to carry the running wheel 50 as the running wheel 50 moves to the bifurcation section 002.

When the supporting plate 00111 at the branching section 002 is connected with the transition plate 00114, and the transition plate 00114 is flush with the supporting plate 00111, at this time, when the running wheel 50 passes through the branching section 002, the running wheel 50 can move to the transition plate 00114, so that the problem that the running of the railway 001 vehicle is affected due to the influence of suspension of the running wheel 50 after the running wheel 50 is separated from the supporting beam 0011 at the branching section 002 is avoided. That is, by providing transition plates 00114, the passage of the rail 001 vehicle through the bifurcated segment 002 can be facilitated.

In addition, when the rail 001 includes the inner side plate 00113, at this time, the guide wheel 110 may be in contact with the inner side plate 00113 during running of the rail 001 vehicle.

In addition, when the two support beams 0011 of the track 001 are each connected with the transition plate 00114 at the branch section 002, at this time, as shown in fig. 8 and 10, the transition plate 00114 brackets on the two support beams 0011 of the branch section 002 may have a gap so that the steering shaft 20 may pass through the gap when the bogie passes through the branch section 002, avoiding the influence of the transition plate 00114 on the steering shaft 20.

Additionally, in some embodiments, the height of the inner side panels 00113 at the bifurcated segment 002 is less than the distance between the connecting bottom beams 0012 and the guide wheels 110 and is greater than or equal to the height of the switch rails 0013, the height of the inner side panels 00113 being the distance from the end of the connecting bottom beams 0012 to the connecting bottom beams 0012, and the height of the switch rails 0013 being the distance from the end of the switch rails 0013 that is remote from the connecting bottom beams 0012 to the connecting bottom beams 0012.

When the height of the inner side plate 00113 at the branch section 002 is smaller than the distance between the connecting bottom beam 0012 and the guide wheel 110, at this time, the guide wheel 110 may not contact the inner side plate 00113 when the railway 001 vehicle travels to the branch section 002, so that the guide wheel 110 does not contribute to a change in the traveling direction of the railway 001 vehicle. When the height of the inner side plates 00113 at the diverging section 002 is smaller than the distance between the connecting bottom beam 0012 and the guide wheels 110, which is greater than or equal to the height of the switch rail 0013, it can be ensured that the switch wheel 80 can be subjected to the force of the switch rail 0013 after entering the switch wheel 80, thereby facilitating the switch wheel 80 to switch the direction of the rail 001 vehicle through the switch rail 0013 and thus switch the direction. That is, by making the height of the inner side plate 00113 at the branch section 002 smaller than the distance between the connecting bottom beam 0012 and the guide wheel 110 and greater than or equal to the height of the switch rail 0013, it is possible to facilitate that the guide rail does not act on the change in the traveling direction of the rail 001 vehicle when the rail 001 vehicle travels to the branch section 002, facilitating that the rail 001 vehicle passes through the switch wheel 80 and the switch rail 0013 passes through the branch section 002.

An embodiment of the application provides a transport system comprising a rail vehicle, a rail, and a bogie according to any of the above embodiments. The bogie comprises a supporting spring, and the railway vehicle is connected with the supporting spring. The track has the bifurcation section, and the bifurcation section includes the bight, and the track includes two supporting beams and connects the flounder, and two supporting beams interval sets up, and two supporting beams connect in the same side of connecting the flounder, are provided with the switch rail on the connection flounder, and the switch rail is located between two supporting beams, and wherein, the switch rail is located bifurcation section department, and the bending direction of switch rail is the same with the bending direction of bight.

Referring to fig. 12, a flowchart of a steering method according to an embodiment of the present application is shown, where the steering direction is applied to the bogie in any one of the foregoing embodiments, and as shown in fig. 12, the steering method includes:

step 1201: the driving member is controlled to drive the driving arm to rotate relative to the driving member, so that the driving arm drives the switch wheel to move between the switch rail and the supporting beam close to the switch rail.

When the railway vehicle runs to the bifurcation section, an instruction can be sent to the driving piece, so that the driving piece can receive the instruction, namely, the driving piece is controlled, the driving piece drives the switching wheel to move between the steering guide rail and the supporting beam through the driving arm, and the switching wheel drives the railway vehicle to steer, so that the railway vehicle can directly pass through the bifurcation section, a turnout structure is avoided being arranged at the bifurcation section, and the efficiency of the railway vehicle passing through the bifurcation section is improved.
