Embodiment Construction

[0035] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, but not to limit the present disclosure.

[0036]Usually rail vehicles have mutually perpendicular x, y and z directions, wherein the x direction corresponds to the longitudinal direction and defines the front and rear orientations, the y direction corresponds to the lateral direction and defines the left and right orientations, and the z direction corresponds to the vertical direction and defines In the upper and lower positions, the front of the car is in the front and the rear of the car is in the back. When the user faces forward, the position of the left hand is the left position, the head is up, and the feet are down. In the present disclosure, for the convenience of description, the bogie assembly of th...

Abstract

The invention relates to a bogie assembly of a railway vehicle and the railway vehicle, and the bogie assembly comprises a door frame type steering framework (1) having the lower end connected with anaxle (21) of a railway vehicle, a swing bolster (3) arranged above the door frame type steering framework (1) and having the two ends, in the Y direction, hinged to a vehicle body of the railway vehicle respectively, a secondary suspension device comprising a shock absorber and enabling the upper end of the door frame type steering framework (1) to be connected with the swing bolster (3) throughthe shock absorber, and a torsion aligning device connected with the door frame type steering framework (1) and the swing bolster (3); and the torsion aligning device is arranged to deform when the swing bolster (3) rotates around the Z-direction central axis so as to provide elastic restoring force opposite to the rotating direction. By means of the technical scheme, the bogie assembly can effectively guarantee torsion return of the vehicle body, and the running stability and riding comfort of the rail vehicle are improved.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle equipment, and in particular, to a bogie assembly of a rail vehicle and a rail vehicle. Background technique [0002] Rail vehicles refer to vehicles running on rails, such as subways, light rails, monorails, short-distance maglev and other rail vehicles. Rail vehicles can run underground, such as subways, or on the ground, such as trains, light rails, etc. whose tracks are built on the ground or elevated. For rail vehicles, the bogie assembly is one of the most important parts of the rail vehicle, which mainly plays the role of supporting the vehicle body, transmitting traction and braking force, and ensuring the safe operation of the vehicle. Therefore, the stability of the connection between the bogie assembly and the vehicle body affects the passenger's riding experience. In the related art, the bogie frame in the bogie assembly is connected to the vehicle body through a secondary s...
