Roof rail for freight wagons

The invention relates to a roof beam for rail freight wagons, in particular sliding wall wagons, which is disposed between the end wall at the end of the wagon and the center bracket attached to the center of the wagon 5 or end walls attached to the ends of the wagon.

The roof beams seal the longitudinal joint between the sliding walls or ceilings on opposite sides of the wagon with respect to the load cross-section and at the same time guide the load shields and secure them in the longitudinal direction of the wagon.

The driving axes for attaching an open sliding wall or for sliding wall opening and locking are likewise often located in the ceiling beam. In addition, the roof beam 15 can substantially increase the strength of the freight wagon body, as it is positioned above the horizontal continuity line of the underframe in the cross section of the wagon.

·. From DD 257 234 a roof beam is known, the upper side of which is: 20 two slightly outwardly sloping support surfaces forming ·: ··: inwardly open passageways and terminating outwards in a vertical region, '; Relevant to the horizontal plate, which is the vehicle transverse direction at a · v 'as wide as the upper supporting surfaces. The free space between the lower beam of the roof beam and the oblique edge 25 is used to receive the guide rollers for the load shield walls.

• The disadvantage of this ceiling beam is the low resistance in vertical and ·; · 'horizontal loads, the v: 30 very low torque caused by the open cross-section and consequently unsatisfactory support of the horizontal loads and rotation of the base frame. Moreover, such a cross-section of the ceiling beam 2 111830 is heavy, since such an open profile must use a thick plate.

Also known is a roof beam for freight wagons, which consists of two outwardly open, L-shaped longitudinal beams, which are connected to each other at the top by a roof plate. The vertical webs of the longitudinal beams are spaced apart by short cross beams.

In the open area extending outwardly from the longitudinal beams, the upper ends of the sliding walls and controls are controlled. The disadvantage of this ceiling beam profile, despite its large angularity, is the low torque and the vertical load resistance. In addition, separate guide rails for the load shield walls must be used, which results in a large welding need.

It is an object of the invention to provide a roof beam having a residual water collecting channel and, if necessary, an integrated fastening device for load protection devices or lifting manipulators which has a high horizontal and vertical load and torsional st lightweight construction and at the same time is lightweight, can be manufactured with minimal effort and is corrosion resistant.

The problem is solved by the invention according to the features of the claims v · ', that is, the outer part of the roof beam is formed by U-shaped upper and lower profile defining half-boxes with residual water on sliding walls on opposite sides. recess parallel to the longitudinal center of the carriage * ·; · *. This outer molded body consists of a thin-walled plate characterized by at least three '·; * a bent angle in the outer profile and having at least one bent: 30 angle in the inner mold, and wherein the ceiling beam shape according to the invention is formed by joining the outer profile lower beam to the lower profile 3 111830, thus forming a ceiling beam the hollow beam utilizing the hollow beams, and the space between these hollow beams on both sides preferably comprises about two-thirds of the space height 5 sliding wall actuator space and the residual water collecting duct load-bearing cross-section.

Unless special load securing devices are required, the invention solves the problem by having the inner molded piece consisting of a flat plate which, at a bent angle a, connects the outer profile with the lower arch to the recess with an upwardly bent angle in the area of angle a to the residual water collection channel. This profile according to the invention can be positioned within the frame of the invention even when rotated 180 °.

One embodiment of the invention will now be illustrated in greater detail by the following drawings, of which: is a cross-sectional view of a roof beam, and FIG. 2 shows a connection between an outer profile lower arch and an inner profile lower arch.

· ;;; The roof beam of Fig. 1 is disposed between the unexposed end wall of the wagon and the center support or wagon end walls. The roof beam consists of two v: 30 hollow beams 1, formed by a recess 6 and formed by • t i * ··· at least three bent angles a, b, c. In the embodiment, the angles a, b, c, d are bent. The hollow beam 1 is a downwardly open profile box closed by a mold piece 3 within it. The shape piece 3 consists of bent angles e, f and is connected to the hollow beam 1 by welding seams 7 and welding seams 8 of Fig. 2 To control and improve stiffening of the load securing devices 5 not shown in more detail, 2 is made up of a board having a thickness of at least half the required thickness of the boards receiving the load-securing walls. Due to the bent angle e, the thickness of the plate is doubled, and the raised end 10 of the plate forms the second curved corner g into the lower trunk 4 of the running rail profile 2. The upper end of the running rail inner profile 3 joins the profile into a solid box. From the water collecting duct, the recess 6 leaves holes 9, 15 of which drain water.

Within the scope of the invention, the profile 3 can be shaped as a simple sheet, i.e. without doubling, or with other known stiffeners. The bent angle g may also be omitted without affecting the basic idea of the invention.
