Bogie and rail vehicle

Abstract

The invention discloses a bogie and a rail vehicle. The bogie comprises a bogie framework; a torsion bar assembly which comprises a torsion bar extending in the transverse direction, rocker arms extending in the longitudinal direction and compression-resistant bars extending in the vertical direction. The torsion bar is provided with a torsion bar mounting position used for being hinged to a vehicle body, and the first end of the torsion bar is fixedly connected with the first end of the first rocker arm; the second end of the torsion bar is fixedly connected with the first end of the second rocker arm, the second end of each rocker arm is rotatably connected with the first end of the corresponding compression-resistant bar, the second end of each compression-resistant bar is hinged to thebogie framework around the axis extending in the longitudinal direction, and the mounting position axis of the compression-resistant bars is in the longitudinal direction. According to the bogie, thetorsion bar assembly is arranged, so that the bogie can prevent or reduce transverse yawing and rolling of the vehicle body, and the stability of high-speed movement of the vehicle body is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of vehicle manufacturing, and in particular relates to a bogie and a rail vehicle. Background technique [0002] During the start-up, braking, curve running and high-speed running of the rail vehicle, the car body nods front and back and shakes left and right, which will easily cause the shaft of the bogie to shake inside, and the impact will cause abnormal noise, which will be transmitted to the compartment through the car body. Adversely affect passenger comfort. [0003] The main functions of the left and right bogies are to play the role of traction, braking and restraining the left and right shaking of the car body. In related technologies, when the rail vehicle is moving in a curve, the car body shakes obviously, and it is prone to impact and abnormal noise. Car body rollover, rollover and other accidents. Contents of the invention [0004] The present invention aims to solve at least one of the te...
