Abstract

The invention discloses a bogie for a railway vehicle and the railway vehicle with the bogie. The bogie comprises a framework assembly, wherein the framework assembly comprises a steering knuckle, a steering knuckle arm and a guide support, a walking wheel is installed on the steering knuckle, the steering knuckle arm is connected to the steering knuckle, the guide support is hinged to a vehicle body of the railway vehicle, a guide wheel is installed on the guide support, the guide support is connected with the steering knuckle through a steering pull rod, the bogie comprises the framework assembly arranged on the left side and the framework assembly arranged on the right side, and the steering knuckle arm in the framework assembly on each side is suitable for being independently installedon the vehicle body of the railway vehicle. According to the bogie for the railway vehicle, the running stability of the railway vehicle can be improved.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a bogie for a rail vehicle and a rail vehicle with the bogie. Background technique [0002] In some rail transit systems in the related art, the rail vehicle realizes the steering along the monorail through the bogie. Specifically, the bogie includes a cross bridge and running wheels connected at both ends of the cross bridge, and the bottom of the cross bridge passes through a guide frame and a slewing bearing Connecting the guide wheels, when the rail vehicle is running along the monorail track, the guide wheels drive the running wheels to turn through the guide frame and the cross bridge. However, if the running wheels on one side of the rail vehicle are bumped, the running wheels on the other side of the rail vehicle will be driven to follow the bumps through the cross bridge, resulting in poor running stability of the whole vehicle and reducing the ride comfort o...
