Method and device for connecting railway vehicle

Abstract

The invention relates to the vehicle linking method and device. The linking hinge is made by female linking hinge base, male linking hinge base, traction pin, semispherical cushion, concave spherical cushion plate and wedge cushion plate, with the male and female linking hinge base fixed on two adjacent vehicle end, single hinge head of the male linking hinge base set to the dual hinge head of the female linking hinge base, with gap between the single and dual hinge head, allowing vertical inter leaping, with the male and female linking hinge base connected through round cylinder traction pin. The hole of the male lining hinge base is spherical, semi spherical cushion between the traction pin and the male linking hinge base, whose front end is boss spherical matching with concave spherical cushion plate, adding wedge cushion plate allowing it linking seamless being universal rotating ball joint.

Description

technical field [0001] The invention relates to a connection method and device for railway vehicles, in particular to a connection method and device for articulated railway freight cars, belonging to the field of railway transportation equipment. Background technique [0002] There are two ways to connect traditional railway wagons. One is vehicles that can be disassembled during transportation. These vehicles are usually connected by coupler buffer devices (or drawbars) to facilitate separation when they need to be disassembled. However, some vehicles are always connected as a whole during transportation, or even during the entire use of the vehicle. This type of vehicle does not have a working condition of disintegration except for maintenance. Vehicles that do not need to be disassembled during transportation can be connected with a tow bar or an Articulated Connector. The structure of the joint connector is simpler than that of the coupler buffer device or the drawbar, ...

AI Technical Summary

Problems solved by technology

Since the bogies are shared by two vehicles, the number of axles is small, and the load of the vehicles is also limited under the condition of limited axle loads, which is not suitable for heavy-duty railway transportation. It is necessary to improve this.
