Technical field

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crossbeam with mounting elements for gripping the bogie and hinges on which a top bogie bogie on the upper side and a bottom bogie bogie on the underside are provided for each side of the bogie. cross beam and protruding over its edge towards the bogie. Its hinge support member is formed by a hinge pin for the lower eye of the hinge, and the hinge support member is located outside the lower chassis clip on the underside of the crossbeam, perpendicular thereto, and extends over the edge of the crossbeam toward the hinge. The invention further relates to a method of manufacturing this crossbeam.

BACKGROUND OF THE INVENTION

It is known to provide a crossbeam with mounting elements for mounting the bogie and hinges on which the upper bogie upper clamp on the upper side and the bogie lower clamp on the lower side are provided for each side of the bogie, and these clamps are provided with flanges arranged in parallel with a crossbeam and extending over its edge towards the bogie, wherein the hinge mounting member is formed by a hinge pin for the lower eye of the hinge, and the hinge mounting member is spaced from the lower bogie bracket, at the underside of the crossbeam, extending over the edge of the crossbeam towards the hinge.

of which the cross beam is composed of hinge assembly elements of a clamp, consisting of parts surrounding the cross beam Because it is extremely important this

In the known rail vehicle, wagon bodies connected by a hinge, for attaching the bogie and from the upper and lower parts which are connected to each other, to adjust the hinge attachment with very small tolerances, the clamp provided with shims which can compensate for dimensional differences with respect to eight points on the underside of the wagon body. The shims are individually ground before the clamp is screwed tightly. During maintenance, the clamp is removed again and during subsequent assembly it is not possible to avoid further grinding or inserting new shims. A split clamp in which the hinge gripping member is located on a bolt mounted in a hole formed in the lower portion of the clamp, and the clamp of the bogie is also mounted on the clamp is relatively heavy.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION A crossbeam with mounting elements for mounting a bogie and hinges on which a top bogie bogie on the upper side and a bottom bogie bogie on the underside are provided for each side of the bogie and the bogies are provided with flanges arranged parallel to the bogie a beam and extending over its edge towards the bogie, and whose hinge receiving member is

-1EN 279849 Ββ located outside, perpendicular to and underneath the chassis retainer on the underside of the crossmember, extending over the edge of the crossmember towards the hinge, the hinge pin forms an elongated portion of the connecting foot located below the crossmember and between adjoining the underside of the crossbeam and the underside of the crossbeam is a layer of filler material of casting resin.

The present invention thus fulfills the task of providing a transverse beam with mounting elements for mounting a bogie carriage and hinge at low assembly and maintenance costs, in which tolerances, particularly hinge fastening, are easy to adjust and can be accurately adhered to, and the connecting elements are as light as possible . Inaccuracies on the wagon side are easily compensated by a filler material such as casting resin, thus eliminating the laborious adjustment of the individual hinge attachment members.

Between the side of the foot facing the cross-member and the underside of the cross-member there is preferably a toothed plate whose teeth fit into corresponding gaps on the facing side of the foot. The filler layer is located between the second, smooth side of the toothed plate and the underside of the crossbeam.

According to a particular embodiment of the invention, on this transverse beam of the bogie clamp are positioned offset from each other in the length direction of the transverse girder, the upper bogie clamp and the hinge mounting member being arranged one above the other.

The principle of the method of manufacturing the crossbeams according to the invention consists in that the wagon body is first measured at the mounting points of the hinge fixtures and the measured difference at these points is determined relative to the leveled horizontal surface and the thickness of the filler layer determined. Further, the hinge mounting members for the corresponding part of the bogie and the toothed plates attached thereto, while maintaining the necessary distance from the center of the bogie and the thickness of the filler mass, are stored in a separate fixture. The jig is lifted and the toothed plates are firmly inserted into the filler. Then the jig is lowered and the toothed plates are bolted to the crossbeam, whereupon the hinges are pressed onto the hinge mounting members and this assembly is pressed onto the corresponding clips on the crossbeam and finally the crossbeam is lifted and the hinge mounting members are screwed to the toothed plates.

The described features of the method of manufacturing the cross-beam as an assembly make it possible, in binding operations using the respective fixture and application of the filler mass according to the invention, to quickly and safely assemble the cross-beam elements in such a position. and chassis.

DETAILED DESCRIPTION OF THE INVENTION

The crossbeam 1 has a rectangular hollow profile with overlaps on its upper and lower sides. The brackets 8 and 9 of the clamps 2a of the 3rd bogie are firmly screwed on the H-shaped offset. Clips

2 and 3 of the bogie have flange extensions that extend over the edge of the crossbeam 1 towards the bogie. The upper bogie clamp 2 is arranged on the crossbeam 1 and the lower bogie clamp 2 is arranged below the crossbeam 1. The two bogie clamps 2 and 3 are offset relative to each other, and under the upper bogie clamp 2 on the underside of the crossbeam 1 the hinge mounting member 4 is located. The hitch mounting member 4 is made in one piece as a connecting foot with a hinge pin 2 for the lifting eye. The hinge pin 7 is arranged perpendicular to the crossbeam 1 and points in the same direction as the clamps 2 and 3 of the bogie. Between the flat connecting foot facing the underside of the crossbeam 1 is a toothed plate 5 which is screwed together with the crossbeam and the hinge mounting member 4. The toothing on the toothed plate 5 extends into the corresponding toothing on the surface of the hinge mounting member 4 facing the beam 1. Between the toothed plate 5 and the underside of the cross beam 1 there is a layer of filler material 6.

The function of the novel features of the invention, that is the arrangement of the gripping member 4 separated under the upper clip 2 of the bogie and the incorporation of the toothed plate 5, is subject to the use of a cast resin filler 6 instead of known solid washers. Its application comes into consideration not only for the first assembly of the crossbeam 2, but also for the overall maintenance of the chassis and the wagon body, in which the differences in the position of the hinge mounting points need to be measured again due to wear and possible deformations. If their position differs from the original values determined during the first production and assembly of the crossbeam 1, as is usual, the existing washers must be adapted or new ones used. The application of the filler material 6 speeds up and simplifies the assembly procedure in both cases.

The advantages of the invention are even more pronounced by the use of the method for manufacturing the crossbeam 1 according to the invention. By way of example, the process used in the manufacture of the crossmember assembly 1 and the wagon body. The sequence of operations was as follows. First, the vehicle body was measured at the hinge mounting mounting points, and the measured difference at these points was determined relative to the leveled horizontal surface. Then, the thickness of the filler layer 6 was determined from the measured difference. Further, the hinge attachment members 4 for the corresponding part of the bogie and the toothed plates 5 attached thereto were kept in a separate fixture while maintaining the necessary distance from the bogie center and the filler thickness. The jig was lifted and the toothed plates 5 were firmly inserted into the filler 6. Then the jig was lowered and the toothed plates 5 were bolted to the crossbeam 1, then the hinges were pressed onto the hinge mounting members 4 and this assembly was pressed onto the corresponding clips on the transverse. In the end, the crossbeam 1 was lifted and the hinge attachment members 4 were bolted to the toothed plates 5.
