Railway car

Abstract

The present utility model relates to design of open wagons used for transporting cargo that does not require protection from atmospheric precipitation. Disclosed is a railway car comprising at least two bodies supported by carriages, each body comprising a frame, two side walls and two end walls. Said at least two bodies are sequentially coupled to each other by means of at least one joint assembly, wherein each body is supported by two carriages, and wherein bodies adjacent to each joint assembly are supported by one common carriage. The distance between the closest points of mutually facing end walls of the neighboring bodies of said at least two bodies arranged on a straight track section is less than 800 mm. The technical result lies in increase of useable volume of the space between sequentially arranged railway car bodies and decrease of empty weight-to-carrying capacity ratio of the railway car.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims priority to Russian Application No. 2014133355 filed 13 Aug. 2014, herein incorporated by reference in its entirety.TECHNICAL FIELD[0002]The present utility model relates to railway transport, in particular to design of open wagons used for transporting cargo that does not require protection from atmospheric precipitation, i.e. bulk non-powdered cargo, dry bulk cargo, stockpiled cargo and unit load cargo, and to design of covered wagons used for transporting cargo that requires protection from atmospheric precipitation.BACKGROUND ART[0003]Presently, four-axle open wagons and covered wagons are widely used in railway transport.[0004]Generally, four-axle wagons in a freight train are coupled to each other by means of automatic couplers known in the art.[0005]An example of such wagon is a universal open wagon of 12-9761 model with unloading gates manufactured by the company “Tikhvinsky vagonostroitelny zavod” (Tikhvin ...

AI Technical Summary

Benefits of technology

The present utility model describes an open wagon that increases the useable space between sequentially arranged open wagon bodies and reduces the distance between end walls of neighboring bodies. This design also reduces the number of carriages required for transporting the same cargo and allows for a fuller carrying capacity usage when transporting cargo with relatively low specific density. Additionally, the open wagon design reduces the mass of each part, resulting in lower manufacturing and operating costs while providing increased cargo transportation efficiency.

Problems solved by technology

The disadvantage of the described open wagon of 12-9761 model is ineffective usage of space between neighboring open wagons, said space occupied by coupler devices, e.g. automatic couplers, and free of transported cargo.

Furthermore, said disadvantage is responsible for low load per unit length of the knoen open wagon, load per unit length defined as ratio of car load per one meter of railway track.
