Abstract

The invention relates to exterior longitudinal beams (1) for twin axle railway goods wagons which are designed to transmit the horizontal buffer forces and to receive the vertical load of the freight and have the devices for bearing the axles (3). The object of the invention has been to provide an exterior longitudinal beam (1) for twin axle railway goods wagons, which beam (1) consists of simple components which can be manufactured economically and permits a simple and economical arrangement of the necessary crossbeams, which reduces the noise emission of the running gear and improves the aerodynamic properties in the underframe area. This object is achieved in that the exterior longitudinal beam (1) consists continuously from the headstock (2) to the headstock (2) of the railway goods wagon exclusively of multiply edged sheet metal with the same wall thickness. Here, the exterior longitudinal beam (1) has a joint-free cross-section. The exterior longitudinal beam (1) is also of three-level design at its upper longitudinal side, the uppermost level (6) forming the loading level, the central level (7) being the support surface for the floor covering (8) and the lower level (9) forming the support surface for crossbeams (10) of the railway goods wagon. <IMAGE>

Description

Technical field

The invention relates to outer side members for two-axle rail freight wagons which are designed to transmit horizontal buffer forces and to absorb the vertical load of the loaded material and which carry the axle-bearing device.

BACKGROUND OF THE INVENTION

The outer longitudinal members for two-axle freight wagons generally consist of a passage, cylindrical or bent or welded profile, in which there are protruding, domed reinforcements in the form of trusses or sheet metal outer profiles arranged between the axles. The axle retainers formed in the known sheet metal are welded to the axle brackets and are provided with a caliper even at the axle brackets which secure the axle brackets by embracing them from the inside and being welded under the outer brackets. The production of these known outer longitudinal members is carried out from a large number of separate components which have to be welded to one another in an economically disadvantageous manner.

A further disadvantage of these known outer longitudinal members is that it is necessary to precisely fit the crossbeams which must be butt-welded against the outer longitudinal members.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION It is an object of the invention to provide an outer longitudinal member fctt ffr *. - ^ -----> · »..» ,, <, (.'kí. * <· .1. · .. ·. ·. ·· - ......— ..

for two-axle rail freight wagons, which would consist of simple, economically viable components, which would allow simple and economical arrangement of the necessary crossbars, which would reduce the noise emission of the bogies, and which would improve the aerodynamic properties of the bogie region.

The object is achieved by an outer longitudinal member according to the invention, which is based on the fact that the outer longitudinal member continuously between the rails of the freight wagon consists only of multi-folded sheet metal with the same wall thickness. In this case, the outer longitudinal k is formed in a cross-section continuous. This embodiment of the outer longitudinal member according to the invention creates a simple, economically feasible component which can advantageously consist of a single structural element.

According to the invention, the outer longitudinal k is formed on its upper longitudinal side in three stages, the highest step being the loading plane, the middle step of the floor covering and the lower step of the rail freight wagon. By means of this staggered design of the outer longitudinal member in its upper region, the free insertion of the floor covering and the cross-member of the freight wagon as well as their fastening economically and by simple means are made easy in terms of dimensional accuracy.

The outer longitudinal member according to the invention is led through the axles to the end faces continuously at the same construction height. By means of these so-called longitudinal cover plates, which overlap the axle areas of the rail freight wagon, the emission of noise from the bogie is substantially reduced. At the same time, the aerodynamic properties are improved, in particular the air resistance and the wind noise are reduced.

In the area of the axles, openings are provided downwardly in the outer longitudinal members for receiving the axle boxes, which, as is known, can be closed down by means of the axle retainer keys and sliding guides are arranged on the vertical edges of the notch for longitudinal bearing. .

By means of this embodiment of the invention, the outer longitudinal k is also involved in the bearing arrangement of the axle boxes in addition to its involvement in the horizontal force transfer and vertical forces collection tasks. This embodiment advantageously ensures a reduction in the number of components required and thus an economically advantageous embodiment.

According to the invention, furthermore, on the inner side of the outer longitudinal member of the cutout, there are provided a plurality of elastic longitudinal members and which are rigidly clamped upwardly on the outer provided before the axle box housing are an outer longitudinal member with defined spacing.

The transverse stiffness of the axle guide can be advantageously defined by the arrangement of these spring blades.

DETAILED DESCRIPTION OF THE INVENTION

The outer longitudinal member X according to the invention is shown in FIG. 1 is shown on a two-axle rail freight outer longitudinal to X, wagons with sliding walls.

it comprises between the fronts 2 of the freight wagon a multi-folded sheet of identical cross-section, which is only in proximity to the front metal of the freight wagon in the area of the axles of the envelope, which is provided with cut-outs 13.

The outer longitudinal member 1 has at its upper longitudinal side a three-step edging, the highest step 6 being arranged in the loading plane of the freight wagon and forming its side frame, the middle step 7 forming a bearing for the floor covering and the lower step 9 adapted to accommodate the required crossbar 10 railway freight chassis ✓

wagon. The vertical region 11 of the outer longitudinal member X on its lower longitudinal side with the horizontal rib side passes with the same cross-section through the axles 3 up to the part of the metal.

Second

Near the endplates 2, the outer longitudinal member X is cut and tapered from below so that it extends to the height of the headers 2. This narrowing of the outer longitudinal length is effected by punching or cutting the outer longitudinal length toward the longitudinal end.

X.

The axle regions are provided with bottom open cut-outs for receiving the axle box 14 of the axle

Third

These slots 3 are lockable by means of the axle retaining keys 15.

Sliding guides 16 are mounted on the long edges of the notch 13 for longitudinal bearing of the axle box.

14. The openings in the vertical region 11 of the outer member X at the level of the spring blades 4 are used to check the braking device.

On the inner side of the outer longitudinal member 1, spring blades 18 are arranged on both sides of the slot 13.

These spring blades 18 are rigidly clamped upwardly on the outer member 14 ^and are provided in the region of the axle box 14 at a defined distance before the outer member 7 and serve to transmit transverse forces between the chassis and the axle box 14.
