Traction beam, central traction device, bogie and rail vehicle

Abstract

The invention relates to the technical field of rail vehicles, and provides a traction beam, a central traction device, a bogie and a rail vehicle. The traction beam comprises a center pin bush mounting cylinder, a traction beam body, two transverse stop mounting parts, two longitudinal stop parts and two vertical stop parts, the traction beam body comprises a first traction beam main body and a second traction beam main body, and the first traction beam main body and the second traction beam main body are correspondingly connected with the two opposite sides of the center pin bush mounting cylinder respectively; the two transverse stop mounting parts are correspondingly connected with the first traction beam main body and the second traction beam main body respectively, the two longitudinal stop parts are correspondingly installed on the two opposite sides of the center pin bush mounting cylinder, and the two vertical stop parts are correspondingly installed on the two opposite sidesof the center pin bush mounting cylinder. The traction beam is compact and reasonable in structure, the installation space is greatly reduced, the multifunctional installation connector requirement ofthe bogie and the space limiting area requirement of the bogie can be met at the same time, and the layout difficulty of the traction beam during bogie design is reduced.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a traction beam, a central traction device, a bogie and a rail vehicle. Background technique [0002] The central traction unit of a rail vehicle is used to transmit traction and braking forces between the bogie and the car body. The setting of the central traction device can cause a certain relative movement between the car body and the bogie, which is beneficial to improve the curve passing ability of the rail vehicle, slow down the impact between the car body and the bogie, and reduce the distance between the wheel and the rail in the curved section. wear and tear. [0003] At present, in the research and development and design process of narrow-gauge rail vehicles, due to the special operating conditions, the bogie puts forward higher space restrictions on the traction beam, which in turn increases the difficulty of the layout of the central traction device when design...

AI Technical Summary

Problems solved by technology

[0003] At present, in the research and development and design process of narrow-gauge rail vehicles, due to the special operating conditions, the bogie puts forward higher space restrictions on the traction beam, which in turn increases the difficulty of the layout of the central traction device when designing the bogie.

That is to say, the drawing beam of the prior art is difficult to simultaneously meet the requirements of the bogie multi-functional installation interface and the bogie space-limited area requirements
