Description

The inventive utility model relates to railway transport and relates to the design of the cantilever part of the spinal beam frame of the freight car.

Known cantilever part of the spinal beam containing front and rear stops, patent of Russia No. 2395419 RU, B61G 7/10, publ. 07/27/2010.

The technical problem inherent in this device is the weak connection of the front and rear stops with the cantilever part of the spinal beam, carried out only using mounting welds.

Also known is the cantilever part of the spinal beam, which contains front and rear stops located in its inner cavity with base elements, with which these stops are sealed and fixed in fixing through windows-grooves cut in the side walls of the cantilever part of the spinal beam, application US 2007/0151941, B61G 7/00, publ. 07/05/2007 (prototype).

The technical problem inherent in this device is the weakening of the spinal beam with large-sized through open windows-grooves intended for placement and fastening of the front stop in them, as well as large-sized through-windows-grooves or holes for mounting the rear stop.

The technical result of the claimed utility model is to increase the strength of the cantilever part of the spinal beam, due to a more reliable connection of the front and rear stops for the coupler with the cantilever part of the spinal beam of the railway freight car frame.

The specified technical result is achieved by the cantilever part of the spinal beam of the frame of the freight car, containing front and rear stops located in its internal cavity with basing elements, by which these stops are sealed and fixed in fixing through windows-grooves cut in the side walls of the cantilever part of the spinal beam, the base elements made in the form of thrust ribs, while to increase the length of the weld and, as a consequence, increase the strength of the connection of the thrust ribs with the side walls of the cantilever noy side sill, thrust formed with reinforcing ribs tides-thickened, forming an enlarged cross sectional view of the thrust rib and forming an elongated coupling surface, the fixing through-window-grooves formed on a return loop, repeating the coupling surface thrust rib; reinforcing tides, thickenings can be made cylindrical.

Comparative analysis with the prototype shows that the inventive node connecting the stops of automatic couplings differs from the prototype in that the base elements are made in the form of stop ribs, while to increase the length of the weld and, as a result, increase the strength of the joint of the stop ribs with the side walls of the cantilever part of the spine , stop ribs are made with reinforcing tides-thickenings, forming an enlarged cross section of the stop ribs and forming an elongated connecting surface, while fixing through windows-grooves are made with a response circuit repeating the docking surface of the thrust ribs; reinforcing tides, thickening made of cylindrical shape. This difference from the prototype gives reason to argue that the proposed technical solution meets the patentability criterion of a utility model - "novelty."

The cantilever part of the spinal beam of the freight car frame is shown in the drawings, where in FIG. 1 shows a general view of the cantilever assembly complete with front and rear stops; in FIG. 2 - the same, spinal beam conditionally not shown; in FIG. 3 - the same, front and rear stops are not conventionally shown; in FIG. 4 is an example of the implementation of reinforcing tides-thickenings of a cylindrical shape.

The cantilever part 1 of the spinal beam of the freight car frame contains a front stop 2 and a rear stop 3 mounted in the inner cavity (Fig. 1, 2). The stops 2 and 3 have thrust surfaces 2.1 and 3.1 for interaction with an automatic coupler (not shown) and base elements made in the form of thrust ribs 2.2 and 3.2, with which the front stop 2 and the rear stop 3 are respectively mounted and secured in the fixing through-windows-grooves 1.1 (Fig. 3), cut in the side walls 1.2 of the cantilever part of the spinal beam 1.

To increase the length of the weld and, as a result, increase the strength of the connection of the stop ribs 2.2 and 3.2 with the side walls 1.2 of the cantilever part of the spine beam 1, the stop ribs 2.2 and 3.2 are made with reinforcing tides-thickenings 2.3 and 3.2, forming an enlarged cross section of the stop ribs and forming an elongated undulating docking surface "A". The fixing through-windows-slots 1.1 are made with a mating, repeating connecting surface “A”, a wave-like surface “B”. To increase the manufacturability of the implementation of reinforcing tides-thickenings 2.3 and 3.3, these elements can be made cylindrical in shape with the corresponding response docking contours of the fixing through-windows 1.1 (Fig. 4).

Installation of the front stop 2 and the rear stop 3 in the console part 1 of the spinal beam is as follows.

In the case of the cantilever part of the spinal beam 1 from a single omega-shaped profile, the stops 2, 3 are made up of several parts, which, after placement of the spinal beam in the inner cavity of the cantilever part 1 and the combination of thrust ribs 2.2 and 3.2 and reinforcing tides-thickenings 2.3 and 3.3 with the corresponding fixing through windows-slots 1.1, are connected, for example, by welding, riveting.

When performing the cantilever part 1 of the spinal beam composite, for example, of two Z-shaped profiles, the front stops 2 and the rear stops 3 can be made integral, for example, in the form of castings. In this case, after placing the stops 2, 3 between the Z-shaped profiles and combining the vertical stop ribs 2.2 and 3.2 and the reinforcing tides-thickenings 2.3 and 3.3 with the corresponding fixing through-windows 1.1, the Z-shaped profiles are connected to each other, for example, by welding .

The technical result, which consists in increasing the strength of the cantilever part 1 of the spinal beam, is achieved as follows.

The implementation of reinforcing tides-thickenings 2.3 and 3.3 on the persistent ribs 2.2 and 3.2 increases the length of the mounting welds, with which the stops 2 and 3 are fixed in the inner cavity of the cantilever part 1 of the spinal beam. Tides-thickenings 2.3 and 3.3 serve as additional load-bearing elements that increase the strength of the thrust ribs 2.2 and 3.2, eliminating the need for large-sized through-hole fixing window-grooves or several through-holes, as is done in the prototype, which increases the strength and rigidity of the cantilever part 1 of the spinal beam .

Thus, the proposed design of the connection unit stops automatic coupling, can significantly increase the strength of the cantilever part 1 of the spinal beam.
