[0007] A dust cover is installed on the outer side of the guide wheel shaft.

[0008] The connecting column is axially provided with a cantilever shaft mounting hole.

[0009] The cantilever shaft passes through the cantilever shaft installation hole and is fixed to the base of the bogie body.

[0010] One end of the cantilever shaft fixed to the base of the bogie body is connected with a driving mechanism.

[0011] The driving mechanism comprises a driving plate with a mounting hole in the middle and a driving chain fixedly connected to the driving plate, and adjacent driving chains are connected end to end.

[0012] One end of the cantilever shaft connected to the driving plate is connected to the driving plate through a retaining ring.

[0013] One end of the cantilever shaft passing through the cantilever shaft mounting hole is mounted with a spherical bearing.

[0014] The above-mentioned spherical bearing includes a sphere with a sphere mounting hole axially opened, an upper ball sleeve and a lower ball sleeve respectively sleeved on the outside of the sphere, an oil seal, a first bearing, a second bearing, a fixing nut and an electric slip ring that are sequentially sleeved on the cantilever shaft and located in the sphere mounting hole, and an oil groove is opened on the outer periphery of the sphere.

[0015] The upper ball sleeve and the lower ball sleeve are fixed by screws.

[0016] The beneficial effects of the utility model are as follows: the utility model adopts two guide wheels to replace two groups of guide wheels, thereby saving space and material costs; the guide wheels and the running wheels are installed on one installation body, which saves installation screws and the risk of derailment caused by loose screws, thereby improving the safety factor.
