Abstract

The invention discloses a bogie for a rail vehicle and a rail vehicle with the same. The bogie includes: a frame assembly, the frame assembly includes a steering knuckle, a steering knuckle arm, and a guide bracket, and the steering knuckle is installed There are running wheels, the steering knuckle arm is connected to the steering knuckle, the guide bracket is hinged to the body of the rail vehicle, and guide wheels are installed on the guide bracket, and the guide bracket is connected with the steering rod through a steering pull rod. The bogie includes the frame assembly on the left side and the frame assembly on the right side, and the steering knuckle arms in the frame assembly on each side are suitable for being independently installed on rail vehicles body of the car. According to the bogie for a rail vehicle of the present invention, the running stability of the rail 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...
