Description

The utility model relates to railway rolling stock, in particular to the design of hopper cars.

Known indoor hopper car for transportation of mineral fertilizers (Wagons. Design, theory, calculation, ed. L. Shadur, M: "Transport", 1980, p. 324), containing a roof with loading hatches, side walls , end walls, inclined at an angle of 60 °, and in the lower part there are side bunkers with hatches and covers for unloading mineral fertilizers on both sides of the railway track.

The prior art hopper car (RU 149541 U1, publ. 01/10/2015, IPC B61D 7/00), comprising a running gear and a body, which is mounted on the running gear and contains at least two successive sections for receiving cargo. The chassis contains at least three trolleys, each body section resting on two trolleys, and adjacent body sections resting directly or indirectly on a common trolley with the possibility of rotation relative to it. Each section of the body contains discharge hoppers for unloading the transported cargo. The extreme sections of the body have a cantilever part in which at least one discharge hopper is located, as well as the end wall is made vertical.

The technical problems inherent in this solution are the low dynamic characteristics of the hopper car when transporting goods with high bulk density due to the uneven distribution of loads acting from the loaded body to the running trolleys along the normal (vertical loads) arising due to the asymmetry of the body section of the hopper car articulated type relative to the transverse plane (perpendicular to the longitudinal axis), due to the support of articulated sections on a common trolley, and uneven distribution of cargo of high bulk density inside the body of the section. In addition, with an uneven distribution of the loads acting from the loaded section body on the bogies, the loading capacity of the hopper car will not be fully used, which reduces the efficiency of transportation.

The technical result of the claimed utility model is to improve the dynamic characteristics of a loaded articulated hopper carriage when transporting goods with high bulk density by providing the body structure in the cantilever part of the section with a uniform load distribution acting normally on the undercarriage from the loaded sections.

The indicated technical result is achieved by an articulated hopper car, including a running gear and successively arranged sections for receiving cargo, mounted on the running gear and interconnected by an articulation device, the body of each section contains side and end walls, each of the end walls in the console parts of the articulated bodies sections made with an inclined section at an angle α to a plane perpendicular to the longitudinal axis of the car, maintained in the range of values from 1 ° to 50 °, while the upper boundary the end wall is located closer to the center of the section body than the lower boundary of the end wall. Angle α can be made in the size range from 5 ° to 20 °. The inclined section may be made in the lower part of the end walls, in the upper part of the end walls and / or in the middle part of the end walls. The inclined section can be performed along the entire end wall.

The inventive utility model differs from the prototype in that each of the end walls in the cantilever parts of the bodies of the articulated sections is made with an inclined section at an angle α to the vertical to the plane perpendicular to the longitudinal axis of the car, maintained in the range of values from 1 ° to 50 °, with the upper boundary the end wall is located closer to the center of the section body than the lower boundary of the end wall. This difference gives reason to argue that the proposed technical solution meets the patentability criterion - novelty.

The essence of the claimed utility model is illustrated by the drawing, which shows the articulated hopper car (schematic view).

The articulated hopper car includes a running gear 1 and sequentially arranged sections 2 for transporting goods mounted on the running gear 1, interconnected by an articulating device 3, while adjacent sections 2 in the area of the articulating device 3 are supported directly or indirectly on one common intermediate running gear trolley 1. The body of each section 2 contains side walls 4, end walls 5 and unloading hoppers 6. In the presented version, there is also a unloading hopper 6. in the console part of the frame. the console part of the body of section 2, the end wall 5 of the body is made with an inclined section 7 at an angle α to a plane 8 perpendicular to the longitudinal axis 9 of the hopper car, in the presented embodiment, the angle of inclination α is 10 °, and the upper boundary of the end wall 5 is located closer to the center of the body section 2 than the lower boundary of the end wall 5.

The technical result of the claimed utility model, which consists in improving the dynamic characteristics of a loaded articulated hopper car when transporting goods with high bulk density, is achieved as follows.

The execution of the end wall in the console part of the body of the section with an inclined section at an angle α to the plane perpendicular to the longitudinal axis of the car, in the range of values from 1 ° to 50 ° with the location of the upper boundary of the end wall closer to the center of the body of the section than the lower boundary of the end wall allows you to shift the center of gravity of the loaded section of the hopper car, to compensate for the asymmetry of the body of the section of the hopper car and to ensure an even distribution of the loads acting on the bogies from the side of the sections along the normal, in particular odovye bogie console in the body parts of the articulated section, and an intermediate hopper car bogie, which provides improved dynamic performance loaded wagon hopper jointed type.

A minimum inclination angle α of 1 ° ensures a minimum displacement of the upper part of the end wall to the center of the section body relative to the lower boundary of the end wall. The maximum angle of inclination α, equal to 50 °, is selected based on the angle of repose of the loads (mineral fertilizers) with the largest cargo turnover (the most massive) to ensure that the internal volume of the cantilever body is completely filled with cargo during loading operations. The implementation of the angle of inclination α in the size range from 5 ° to 20 ° is the most preferred embodiment of the inclined section of the end wall in the cantilever body part of the articulated sections of the hopper car, since this range provides the optimal shift of the center of gravity of the loaded section of the hopper car, which allows optimal to compensate for the asymmetry of the body and the even distribution of the loads acting on the undercarriage in the cantilever bodies of the articulated sections when transporting a large number of different s goods with a wide bulk density, which leads to optimal improvement of dynamic characteristics laden hopper cars.

The execution of the inclined section in the lower, middle and upper parts of the end wall or along the entire end wall in the cantilever part of the body equally provides a shift in the center of gravity of the loaded section of the hopper car and even distribution of the loads acting from the loaded section on the undercarriage, which improves dynamic characteristics of a loaded articulated hopper car. The most preferred option is to perform an inclined section in the middle and lower part of the end wall, which provides optimal improvement in the dynamic characteristics of a loaded hopper car.

Thus, the claimed utility model, with its entire set of essential features, allows to improve the dynamic characteristics of a loaded articulated hopper carriage when transporting goods with high bulk density by providing the body structure in the cantilever part of the section with a uniform load distribution acting normally on the side trolleys from the side loaded sections, when transporting goods in a wide range of densities.
