Problems solved by technology

In the related art, the bogie frame in the bogie assembly is connected to the car body through a secondary suspension device. When the rail vehicle passes through a curve, the car body rotates around the central axis in the Z direction relative to the bogie assembly, thereby affecting the running of the vehicle. Stability, reducing passenger comfort

Embodiment Construction

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

[0036]Generally, rail vehicles have x, y and z directions perpendicular to each other, where x corresponds to the longitudinal direction and defines the front and rear orientations, y corresponds to the transverse direction and defines the left and right orientations, and z corresponds to the vertical direction and defines the Up and down positions, the front of the car is in front and the rear of the car is behind. When the user is facing forward, the position of the left hand is the left position, the head is up and the feet are down. In this disclosure, for the convenience of description, it is defined hereinafter that the bogie assembly of a rail vehicle ...

Abstract

The present disclosure relates to a bogie assembly of a rail vehicle and a rail vehicle, the bogie assembly includes: a door frame type bogie frame (1), the lower end of the door frame type bogie frame (1) is connected to the axle (21) of the rail vehicle ) connection; the bolster (3) is arranged above the door frame type steering frame (1), and the two ends of the bolster (3) in the Y direction are respectively hinged to the body of the rail vehicle; the secondary suspension device includes a shock absorber , the upper end of the door frame steering frame (1) is connected to the bolster (3) through a shock absorber; And the twist back device is configured to deform when the bolster (3) rotates around the central axis in the Z direction, so as to provide an elastic restoring force opposite to the direction of rotation. Through the above-mentioned technical solution, the bogie assembly can effectively ensure that the car body is twisted back to normal, and improve the running stability and riding comfort of the rail vehicle.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle equipment, in particular, to a bogie assembly of a rail vehicle and the rail vehicle. Background technique [0002] Rail vehicles refer to vehicles that run on rails, such as subways, light rails, monorails, and short-distance maglevs. 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 components of the rail vehicle, which mainly supports the car body, transmits traction and braking forces, and ensures the safe operation of the vehicle. Therefore, the stability of the connection between the bogie assembly and the car body affects the ride experience of passengers. In the related art, the bogie frame in the bogie assembly is connected to the car body through a secondary suspension device. When the rail vehicle passes thr...
