A lightweight railway wagon underframe

Abstract

A light weight wagon chassis is composed of a steel floor, a middle beam assembly, sleeper beam assemblies, large beam assemblies, small beam assemblies, a train tail device installation base, an auxiliary beam assembly and an auxiliary longitudinal beam assembly. The two ends of the chassis are provided with the train tail device installation base and the auxiliary beam assembly. The middle beam assembly is located in the middle of the chassis in the longitudinal direction of the chassis. The sleeper beam assemblies are arranged at the two ends of the chassis respectively. The three large beam assemblies and the two small beam assemblies are arranged between the two sleeper beam assemblies. The two ends of the sleeper beam assemblies and the two ends of the large beam assemblies are connected with the middle beam assembly and side walls of an open wagon with the chassis in an assembly welding mode. The steel floor is laid on the upper face of the chassis so that the chassis can be of an integral force bearing frame structure without end beams or side beams. According to the light weight wagon chassis, the end beams and the side beams of a chassis of a traditional open wagon are omitted, the light weight design is adopted, the self-weight of the chassis is effectively reduced, and the light weight wagon chassis has the advantages of being simple in structure, excellent in manufacturability, light in self-weight, large in longitudinal impact bearing capacity, and the like.

Description

Technical field: [0001] The invention belongs to the field of mechanical design and manufacture, in particular to the field of railway transportation equipment, in particular to a lightweight railway wagon underframe. Background technique: [0002] Due to the great differences in the national conditions, railway road conditions and railway vehicle transportation equipment of various countries in the world, the application conditions of railway freight cars are very different, especially in some economically underdeveloped countries, the railway transportation equipment is backward, and the overall structure of the vehicle is commonly stressed. Unsatisfactory, short service life of vehicles, insufficient rigidity and strength reserves, etc., cannot give full play to the role and effectiveness of railway transportation equipment. Invention content: [0003] The technical problem to be solved by the present invention is to provide a light-weight railway freight car underframe...
