Problems solved by technology

[0002] In the rail vehicles in the related art, the running wheels and the horizontal wheels run along the track beams. When the vehicle needs to turn, the horizontal wheels are affected by the track beams and drive the overall steering of the bogie. The horizontal wheels are prone to derailment, and it is difficult to achieve high-speed rail vehicles Steering turns that affect rail vehicle performance
[0003] For this reason, some rail vehicles are equipped with a guide frame to enable the running wheels to realize self-guiding. The guide frame cooperates with the bridge body to steer through the support wheels, but the cooperation between the support wheel and the two cannot make the guide frame rotate smoothly relative to the bridge body, which affects the stability of the rail vehicle. guiding performance

Abstract

The invention discloses a bogie for a rail vehicle, the rail vehicle, and a rail transit system. The bogie includes: a bridge main body, a guide frame, and a slewing bearing; the bridge main body is connected with a vehicle frame of the rail vehicle; the guide frame is rotatably mounted on the bridge main body relative to the bridge main body in a horizontal direction; and the slewing bearing includes an outer ring and an inner ring rotatably fitted in the outer ring, the guide frame is mounted on the outer ring, the bridge main body is provided with a slewing bearing mounting seat, and the inner ring is installed on the slewing bearing mounting seat. The bogie of the rail vehicle of embodiments of the invention can be self-guided, and has the advantages of smooth steering, and the like.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a rail vehicle bogie, a rail vehicle having the rail vehicle bogie and a rail transportation system having the rail vehicle. Background technique [0002] In the rail vehicles in the related art, the running wheels and the horizontal wheels run along the track beams. When the vehicle needs to turn, the horizontal wheels are affected by the track beams to drive the overall steering of the bogie. Steering turns that affect rail vehicle performance. [0003] For this reason, some rail vehicles are equipped with a guide frame to enable the running wheels to realize self-guiding. The guide frame cooperates with the bridge body to steer through the support wheels, but the cooperation between the support wheel and the two cannot make the guide frame rotate smoothly relative to the bridge body, which affects the stability of the rail vehicle. guiding performance.
