Problems solved by technology

At present, in the existing technology, the knuckles for railway vehicles are all manufactured by casting process, but because the casting process will inevitably lead to fatigue crack sources such as trachoma, shrinkage cavity, shrinkage porosity, etc., it is very easy to cause cracks in the knuckle during use or break

Abstract

A coupler knuckle for railway vehicle has a draft surface (1) and a knuckle pivot pin hole (2). A bounce table (3) lies on the knuckle pivot pin hole (2), and a traction table (4) lies on the bounce table (3). A nose (5) of the coupler knuckle is provided in the lower part of the coupler knuckle. The bottom surface of the coupler knuckle's nose forms the coupler knuckle's face (6). There is a first groove (61) on the coupler knuckle's face (6). The coupler knuckle is a forging piece. The coupler knuckle has the advantage of high reliability, low cost and is easy to be transported.

Description

technical field [0001] The invention relates to the technical field of railway vehicles, in particular to a knuckle used for railway vehicles. In addition, the present invention also relates to a railway vehicle including the aforementioned knuckle. Background technique [0002] Generally speaking, a railway vehicle is mainly composed of a car body, a running part, a braking device, a coupler buffer device and internal equipment of the vehicle. The coupler is an important part of the coupler buffer device. The coupler is used to realize the connection between the railway locomotive and the vehicle or between the vehicle and the vehicle, transmit traction and impact force, and keep a certain distance between the vehicles. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of an automatic coupler for a railway vehicle in the prior art. [0004] The coupler that railway vehicle uses in the world is mainly automatic coupler at present, and so-c...
