Definitions
- Rail vehicle component made of light metal hollow sections.
- the invention relates to a method for producing a rail vehicle large component of light metal hollow sections and a light metal hollow section.
- the car body of a passenger rail vehicle can be manufactured by means of so-called integral construction, in which metal profiles are connected to large components and these in turn to a car body.
- the large components typically provide a side wall, a base, a roof or an end wall, wherein as a joining technique of the metal profiles with each other and to connect the
- the invention is therefore based on the object of specifying a method for producing a rail vehicle large component of light metal hollow sections, which allows to meet specific strength requirements at certain positions of the large component and thereby the lowest possible weight of the large component at high Degree of automation and associated low
- the basic idea of the invention is based on a method for producing a rail vehicle component
- Rail vehicle large component to be able to build which is on the one hand automated and inexpensive to produce, on the other hand, as flexible localization of local strength requirements as by means of a
- typically several, light metal hollow sections are connected together and then removed parts of a cover layer of the composite light metal hollow sections.
- weight may be present can be saved without significantly reducing the required strength of the large component.
- the surface to be removed of the cover layer is of the
- the remaining after removal of the cover layer webs form on the one hand stiffening ribs in the large component, On the other hand, they can be used for the attachment of interior fittings such as wall coverings, etc.
- a particularly advantageous embodiment of the invention provides to leave below the removed areas of the cover layer also portions of the underlying webs, i. not completely remove these webs.
- the advantage can be achieved of achieving a reduction in the component mass without significantly reducing the dimensional stability. Even short remaining portions of the webs cause a large stiffening of the outer wall, in particular a significantly increased BeulsteifIER.
- a particularly advantageous embodiment of the invention provides to use light metal hollow sections, which are optimized for the partial removal of the webs out, with the remaining sections of the webs particularly
- the hollow profile can be executed closed with two cover layers, wherein the cover layers are interconnected with webs and wherein the webs have a first portion which is perpendicular to a cover layer and after this first portion, the webs have a branch. If such a hollow profile is processed, wherein the webs are removed so that the first, oriented perpendicular to the cover layer portion and a certain portion of the branch remains, the entire shows
- Such a T-shaped cross section of a remaining portion of a web is extremely advantageous because it has a particularly high stiffening of the remaining
- Interior paneling is suitable.

- Fig.l shows an example and schematically a light metal hollow section. It is a cross section of a light metal hollow section 2 shown, as shown in this subject
- the light metal hollow section 2 is designed to be closed and has an inner cover layer 3 and an outer cover layer 4. It is finished on the installation arrangement of the profile in one
- the light metal hollow profile comprises 2
- Embodiment three webs 5 are provided.
- the webs 5 have an outgoing from the outer cover layer 4 first section 6, which is oriented perpendicular to the outer cover layer 4.
- FIG. 2 shows by way of example and schematically connected
- Rail vehicle large component It is a section of one Rail vehicle major component 1 shown, which is designed as a side wall.
- Large component 1 is made of several light metal hollow sections 2, as shown in Fig. 1,
- Fig. 4 shows by way of example and schematically a machined light metal hollow profile. It is the light metal hollow profile 2 from Fig.l after removal of part of the inner
- the remaining part of the webs 5 in this case has a substantially T-shaped cross-section and thereby offers a high increase in the Beulsteiftechnik the profile.
- FIG. 5 to 12 illustrate embodiments of light metal hollow sections, which can be used in representational process.
- a section through a machined profile is shown, wherein in each case a cross section of a web is shown.
- the sections of the web to be removed and the removed inner cover layer are drawn by dashed lines.
- Fig. 5 shows by way of example and schematically a light metal hollow profile with a T-shaped web.
- the light metal hollow profile 2 is shown in that embodiment, which is shown in Figs. 1 to 4 applied.
- the profile 2 has an inner cover layer 3, which faces the interior of a constructed from the profile 2 rail vehicle in the installed state, further comprises an outer cover layer 4.
- the cover layers 3, 4 are connected to webs 5, wherein a first portion 6 of the outer cover layer 4 extends vertically and spaced from the outer cover layer 4 in an inner belt 10 branches.
- This inner belt 10 causes a large increase in the Beulsteifmaschine the
- Fig. 6 shows by way of example and schematically a light metal hollow profile with an I-shaped web. It is a
- Light metal hollow section 2 similar to that shown in Figure 5, but with no inner belt is provided, but on the outer cover layer 4 facing away from the end of the first portion 6, the webs branch 5 angled.
- This embodiment can be used when the high
- Fig. 7 shows by way of example and schematically a light metal hollow profile with a double web.
- the light metal hollow section 2 has an outer
- Cover layer 4 directly attached hollow chamber formed of two vertical webs and a belt, wherein of the Corners of this closed chamber in each case a web 5 to the inner cover layer 3 is angled.
- FIG. 8 shows an example and schematically a light metal hollow profile with a C-groove.
- Fig. 8 illustrates the light metal hollow section 2 of Fig. 7, but with the machining done so that only the angled ridges 5 and a central part of the inner belt 10 are removed.
- two L-shaped, mutually facing webs, which form a C-groove and can be used for the attachment of other components remain.
- 9 shows by way of example and schematically a light metal
- FIG. 9 illustrates the light metal hollow section 2 of Fig. 7, but with the machining done so that only the angled webs 5 are removed and the inner belt 10 remains.
- a closed chamber on the outer cover layer 4 is arranged on the machined hollow section 2.
- Fig.10 shows an example and schematically a light metal hollow profile with an L-shaped web.
- Hollow section 2 has an inner belt 10 following the first section 6, at whose ends in each case a web 5 extends at an angle.
- the inner belt 10 extends only to one side of the first portion 6 and thus forms together with this first portion 6 an L-shaped web.
- Fig.ll shows an example and schematically a light metal hollow profile with an angled web.
- This embodiment a light metal hollow profile 2 substantially corresponds to that which is shown in Fig. 6, wherein the first portion 6 is angled to the outer cover layer 4 is arranged.
- Fig. 12 shows by way of example and schematically a light metal hollow profile with a T-shaped web. It is a
- Light metal hollow section 2 shown which is constructed very similar to the profile of FIG.
- the profile of FIG. 5 has a disadvantage, since after the machining to remove the webs 5 burrs remain on the inner belt 10, since the cutting edge for removing the webs 5, the inner belt 10 slicing intersects. In such a place, the burr formation is inevitable and it will be
- FIG. 11 shows a light metal hollow profile 2, which ensures a significantly reduced-lored cut in the removal of the webs 5.
- the inner belt 10 is executed at its ends in each case with a thickening and the webs 5 start from the inner cover layer 3 facing side of these thickenings. At a distance of the webs 5 by means of a machining process, the burr formation is thus significantly reduced at this point.
- Fig. 13 shows by way of example and schematically a light metal hollow profile with a T-shaped web. It is a
