In particular, in the case where the bogie assembly 100 of the railway vehicle is applied to a railway vehicle, and the railway vehicle travels on the track 200, the guide wheel assemblies 30 may be in guiding engagement with portions of the track 200 for guiding engagement with the guide wheel assemblies 30, the direction of extension of the track 200 may be varied, to meet the transportation requirements, the guiding engagement of the guide wheel assembly 30 with the corresponding portion of the track 200 will cause the guide wheel assembly 30 to generate a steering torque, since the guide wheel device 30 is arranged on the guide frame 20, the guide frame 20 is arranged on the axle 10, and the running wheels 11 are arranged at both ends of the axle 10, the steering torque of the guide wheel device 30 is transmitted to the axle 10 through the guide frame 20, then transmitted to the running wheels 11 through the axle 10, thereby, the steering of the running wheels 11 is realized, so that the steering of the running wheels 11 can be more smoothly and stably performed, and the bogie assembly 100 of the railway vehicle can be more reliable.

Further, as shown in fig. 1, the guide wheel device 30 may mainly include a guide wheel 31, and the rotation axis of the guide wheel 31 is disposed obliquely to the horizontal plane. Specifically, the guide wheel 31 will be in direct contact with the corresponding portion of the track 200 and perform guiding engagement, when the guide wheel 31 is in guiding engagement with the corresponding portion of the track 200, the guide wheel 31 will generate acting force on the track 200, and the track 200 will simultaneously generate reaction force on the guide wheel 31, it can be understood that the rotation axis of the guide wheel 31 is obliquely arranged relative to the horizontal plane, and the reaction force of the track 200 on the guide wheel 31 can be decomposed into vertical force and lateral force, so that the arrangement is that the guide wheel 31 is subjected to external force, such as: the leading wheel 31 turns round, or when the leading wheel 31 receives stronger wind-force effect, the effect of external force can be offset to the interaction force of leading wheel 31 and track 200, for example, when external force upwards inclines relative to the horizontal plane, track 200 can just with offsetting with external force with the lateral force to the vertical decurrent reverse action force of leading wheel 31, compared with prior art, the track can only restrict the skew of leading wheel lateral, can prevent like this that leading wheel 31 from upwards squinting and breaking away from track 200, lead to rail vehicle unable normal driving, can make the cooperation of leading wheel 31 and track 200 more reliable and stable like this, can promote rail vehicle's bogie assembly 100's reliability.

Therefore, when the guide wheel 31 is in guiding fit with the corresponding part of the rail 200, an interaction force is generated, the rotation axis of the guide wheel 31 is inclined relative to the horizontal plane, when the guide wheel 31 is in guiding fit with the rail 200 and is subjected to an external force, the interaction between the guide wheel 31 and the rail 200 can offset the external force, so that the guide wheel 31 can be prevented from being separated from the rail 200, the structure of the guide wheel 31 can be more stable, and the reliability of the bogie assembly 100 can be improved.

As shown in fig. 1, the angle between the rotation axis of the guide wheel 31 and the horizontal plane is α, and α satisfies the relationship: alpha is more than 30 degrees and less than 60 degrees. Specifically, the included angle between the rotation axis of the guide wheel 31 and the horizontal plane is set within a reasonable range, so that the guide wheel 31 can be selectively set with the included angle between the rotation axis and the horizontal plane according to specific process requirements and different matching tracks 200, the applicability of the guide wheel 31 can be improved on the premise that the guide wheel 31 is stably and reliably matched with the corresponding part of the track 200 and is prevented from being separated from the track 200, and thus, the installation and the arrangement of the guide wheel 31 on the bogie assembly 100 can be further facilitated, the application of the bogie assembly 100 can be further promoted, and the reliability of the bogie assembly 100 of the railway vehicle can be further improved.

Further, as shown in fig. 1, α satisfies the relation: alpha is 45 degrees, so set up, can make the contained angle between the axis of rotation of leading wheel 31 and the horizontal plane be in value moderate relatively, not only can make the direction cooperation of leading wheel 31 and the corresponding part of track 200 more stable like this, can promote the reliability of bogie assembly 100, and after decomposing into vertical power and the power of side direction with track 200 to the reaction force of leading wheel 31, can make track 200 evenly equal to the vertical power and the power of side direction of leading wheel 31, can further promote the stability and the reliability of bogie assembly 100 like this.
