Description

BACKGROUND OF THE INVENTION

These ridge beams seal the longitudinal joint of two opposite sliding walls or covers in terms of cross-section through the receiving space, and at the same time serve to guide the cargo walls and secure them in the longitudinal direction of the car.

The control shafts for fixing the open sliding wall, or for opening and locking the sliding walls, are also often mounted in the ridge beam. Furthermore, the ridge beam can significantly contribute to increasing the strength of the wagon body by virtue of its mounting high in terms of the cross-section of the wagon with respect to the horizontal axis of inertia of the bogie.

From DD 257 234 a ridge beam is known which is ^and on its upper side formed by two outwardly inclined bearing surfaces, these bearing surfaces forming an inwardly open channel, and extending outwardly into a vertical region, then tapering to a longitudinal axis of the vehicle, the dose2 being placed on a horizontal sheet having approximately the same width in the transverse direction of the vehicle as the upper bearing surfaces. The free space between the lower strand and the obliquely extending sides of the ridge beam is used to catch the guide rollers in front of the

The disadvantage of this ridge beam is a low load moment in vertical and horizontal load, a very low torsional load moment due to the open cross-section and thus only insufficient support of the chassis for horizontal load and turkeys. Furthermore, such a cross-section of the ridge beam has a large weight, since - in such an open profile, a sheet of greater thickness must be used.

Further, a ridge beam for freight wagons is known, which consists of two L-shaped longitudinally open longitudinal beams which are connected to one another at the upper end by an overhead sheet. The vertical webs of the longitudinal beams are connected to each other by short transverse beams. The upper end of the sliding walls and the upper control device are guided in the outwardly open area of the longitudinal beam. The disadvantage of these ridge beams is the low torque load and the load moment for the vertical load despite the great effort in ohrafing. In addition, saϊ, mostatne rails must be provided for guiding the load-bearing walls *, which results in a great welding effort.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION The object of the present invention is to provide a ridge beam with a water collecting duct and, if necessary, with integrated load-bearing arrangements or lifting manipulators which have a high horizontal and vertical load torque and a high torsional load torque and thus contribute to increasing the strength of the vehicle body, allowing easy construction of other vehicle body parts while at the same time having a low tare weight, low manufacturing cost - more than one - resistant to both corrosion and corrosion

This object is achieved by the ridge beam according to the invention, i.e. the outer ridge beam area always consists of U-shaped half-shells which indicate the upper and lower planes of the profile and these half-shells are provided with depressions for the residual water collection from the two opposite sliding walls. This outer profile part consists of a thin-walled sheet, which is always provided with at least three edges on the outer profile and at least one edge in the inner profile, and by joining the lower branch of the outer profile with the lower branch of the inner profile a ridge beam is formed. The beam between the outer edge regions and using the full height of the ridge beam, and the space between the hollow beams arranged on both sides, is preferably made up of two thirds as a storage space for sliding wall control and as a collection channel for residual water. The load-bearing storage space, and the load-protective guide rails are included in the load-bearing cross-section of the ridge beam with their cross-sections.

If no support devices are required for the special load protection devices, the object is achieved according to the invention in that the inner profile part is formed by a planar sheet which connects the lower branch of the outer profile to the recess of the residual water collecting channel. the cross-section of the ridge beam profile, so that the lower branch of the outer profile adjoins the upward-facing edging in the edging region and the residual water collection channel. This profile can be arranged in a cross-section of the car rotated 180 °.

Overview of the drawings

Exemplary embodiments of the invention are shown in the drawing, wherein Fig. 1 is a schematic cross-section of a ridge beam, and Fig. 2 shows the connection between the lower branch of the outer profile and the lower branch of the inner profile.

DETAILED DESCRIPTION OF THE INVENTION. The ridge beam according to FIG. 1 is arranged between the front wall (not shown) and the central portal or between the front walls. The ridge beam consists of two hollow beams 1, between which a recess 6 is formed and the hollow beams 1 are formed by at least three edges f1, f1 on each side. In an exemplary embodiment, the hollow beam 1 is formed by five edges a, fe, fe, fe, fe. The hollow beam 1 is a profile box open downwardly, which is closed by an inner profile piece. This inner profile piece 1 is formed by the edges g and 6 and is joined by the welds 7 according to FIG. In order to guide the load-bearing arrangements (not shown) and for additional reinforcement, a lower branch 6 is formed once again by folding g at an angle of approximately 45 [deg.], Forming a guide rail 2 consisting of sheet metal of at least half the required thickness. chu_for attaching fixation parts of cargo protection walls. By folding g, the sheet is doubled and the overlapping end is folded to the next fold g to the lower limb 4 of the guide rails 2- The upper end of the inner profile 2 of the guide rails 2 adjoins the hollow beam 1 in the residual water collection channel. 2 always in a closed cabinet. In the residual water collection duct, in the recess there are openings 2 for water drainage. .

. Also according to the invention, if the inner profile 2 is formed from only one sheet, optionally without doubling, possibly with other known reinforcements. Also, the boundary g can be omitted without departing from the basic principle of the invention.
