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 restriction requirements for the central traction device, which in turn improves the layout of the central traction device when designing the bogie. difficulty
That is to say, the central traction device in the prior art is difficult to simultaneously meet the requirements of the multi-functional installation interface of the bogie and the space restriction area of ​​the bogie

Abstract

The invention relates to the field of a central traction device, and provides a central traction device for a bogie, a bogie and a rail vehicle. It includes a traction beam composition, a center pin composition and a traction rubber pile. The traction beam composition includes a traction beam, two transverse stopper installation parts, two longitudinal stopper parts and two vertical stopper parts, and the two transverse stopper parts The installation parts are correspondingly installed on both ends of the drawing beam extending along the length direction, the two longitudinal stop parts are correspondingly installed on both sides of the drawing beam along the thickness direction, and the two vertical stop parts are correspondingly installed on both sides of the pulling beam along the thickness direction. The invention realizes the integrated installation of the horizontal stopper, the longitudinal stopper and the vertical stopper on the traction beam, makes the structure of the central traction device more compact and reasonable, greatly reduces the installation space, and can meet the multi-functional installation of the bogie at the same time Interface requirements and bogie space restriction area requirements reduce the difficulty of drawing beam layout in bogie design.

Description

technical field [0001] The invention relates to the technical field of a central traction device, in particular to a central traction device for a bogie, a bogie and a rail vehicle. Background technique [0002] The existing rail vehicle bogie central traction device is mainly composed of a central pin, a traction beam, a traction rod, etc., which are used to bear the traction force and braking force, and to withstand the impact of the bogie relative to the car body, and to meet the gap between the car body and the bogie. relative motion. [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 restriction requirements for the central traction device, which in turn improves the layout of the central traction device when designing the bogie. difficulty. That is to say, it is difficult for the central traction device in the prior art to simultaneously me...
