The variable-track-pitch bogie provided by the embodiment utilizes the lubricating nozzle device 200 to lubricate the wheel rim of the wheel 500, reduces the abrasion of the wheel 500 and prolongs the service life. The wheel 500 is braked by the tread brake device 300. In the actual working process, the distance between two oppositely arranged wheels 500 is adjusted according to different track gauges, the track gauge-variable bogie adjusting device 100 is connected to the lubricating nozzle device 200 and the tread brake device 300, and the track gauge-variable bogie adjusting device 100 can be matched with the tread brake device 300 and the lubricating nozzle device 200, so that the problems that the tread brake device 300 occupies large space, wears rims and is singly suitable for a truck bogie are solved, various track gauge-variable bogies can use the tread brake device 300 to achieve the braking effect, and the universality is high. Meanwhile, as the lubricating nozzle device 200 and the tread braking device 300 are both arranged on the track-variable bogie adjusting device 100, under the adjusting action of the track-variable bogie adjusting device 100, the lubricating nozzle device 200 and the tread braking device 300 can be shifted synchronously during track gauge changing, so that the stability and the reliability of the tread braking function and the wheel 500 lubricating function during different track gauges are ensured.

In other words, under the action of the adjusting device 100 for the track-variable bogie, the relative position of the tread braking device 300 and the wheel 500 is unchanged when the track gauges are different, so that the function of reliable braking performance is realized. Meanwhile, the relative position of the lubricating nozzle device 200 and the wheel 500 is unchanged when different track gauges are used, so that the function of reliable lubricating performance of the wheel 500 is realized.
