Vehicle, in particular rail vehicle, with a high-floor and a low-floor area

The invention relates to a vehicle, in particular a rail vehicle, having a high-floor area and a low-floor area situated lower in relation to the high-floor area.

In rail vehicles with different floor heights, high-floor areas and low-floor areas must be connected to each other. Relatively high demands are placed on the connections, since the resulting vehicle structure must be sufficiently strong and stiff to withstand during the

Be able to carry loads occurring during vehicle operation.

In particular, in vehicles whose car bodies are manufactured with aluminum extruded profiles, there is the problem that aluminum has only greatly reduced strength values in the region of the joints or in the region of welds.

The invention is accordingly based on the object of specifying a vehicle, in particular a rail vehicle, in which a connection of high-floor area and low-floor area with sufficient strength is achieved particularly simply and at the same time with a low use of material. This object is achieved by a vehicle with the features according to claim 1. Advantageous embodiments of the vehicle according to the invention are specified in subclaims. According to the invention, it is provided that a center-length carrier arranged in the high-floor area and a floor element arranged in the low-floor area by means of at least one weld seam extending along or at least also along the Vehicle longitudinal direction extends, are welded directly or indirectly.

A significant advantage of the vehicle according to the invention is the fact that the connection between the center-length carrier and bottom element has a surprisingly high strength. The high strength is based on the fact that the welds according to the invention run along the vehicle longitudinal direction and thus along the longitudinal direction of the central longitudinal member and thus significantly less stressed during vehicle operation than with other arrangement of the welds.

In a particularly preferred refinement of the vehicle, it is provided that an intermediate element which completely or at least partially bridges the height difference between the low-floor area and the high-floor area is arranged between the center-length girder and the floor element and the middle-length girder and the floor element are connected to one another by means of the intermediate element.

If an intermediate element is arranged between the center-length carrier and the bottom element, then the center-length carrier and the bottom element can overlap in the vehicle longitudinal direction. Alternatively it can be provided that the center-length carrier and the bottom element are overlap-free in the vehicle longitudinal direction.

For connecting the center-length carrier with the intermediate element, at least one weld seam is preferably provided, which extends along or at least also along the vehicle longitudinal direction and is arranged between the center-length carrier and the intermediate element.

For connecting the intermediate element to the bottom element, at least one weld seam is preferably provided, which extends along or at least also along the vehicle longitudinal direction and is arranged between the intermediate element and the bottom element. In another particularly preferred embodiment of the vehicle, it is provided that the central longitudinal beam and the floor element overlap in the vehicle longitudinal direction and are welded directly to one another by means of the at least one weld seam extending along or at least along the vehicle longitudinal direction.

With a view to a simple tolerance compensation during the manufacture of the vehicle, it is considered advantageous if the center-length carrier is narrower than the distance between the side walls of the vehicle and one or more intermediate plates are arranged between the central longitudinal carrier and at least one of the side walls of the vehicle. extending transversely, in particular perpendicularly, to the vehicle longitudinal direction and bridging the area between the center-length carrier and the side wall.

With regard to the connection of the intermediate plate or sheets, it is considered advantageous if this or these are each secured with one or more of the following welds in the vehicle:

with a weld which extends transversely, in particular perpendicularly, to the vehicle longitudinal direction and connects the intermediate plate to the side wall of the vehicle, with a weld which extends transversely, in particular perpendicularly, to the vehicle longitudinal direction and connects the intermediate plate to the floor element,

with a weld, which extends transversely, in particular perpendicularly, to the vehicle longitudinal direction and connects the intermediate plate to the intermediate element, and / or with a weld which extends transversely, in particular perpendicularly, to the vehicle longitudinal direction and connects the intermediate plate to the central longitudinal carrier. With regard to the floor element, it is considered advantageous if, in the region of the weld seam or weld seams which extend along or at least also along the longitudinal direction of the vehicle, and indirectly or directly tellangträger and connect the bottom element, the bottom element each having a reinforcing region which extends along the vehicle longitudinal direction. It when the bottom element is formed by a hollow chamber profile and the or the reinforcing regions are arranged in the interior of the hollow chamber profile and are covered by an upper bottom plate of the hollow chamber profile is particularly advantageous. The hollow chamber profile is preferably an extruded profile part and the reinforcement region (s) are preferably formed by extruded profile sections.

The hollow chamber profile and the central longitudinal beam are preferably made of aluminum.

With a view to a minimal cost of materials, it is considered advantageous if the width of the intermediate element seen in the horizontal vehicle plane transverse to the vehicle longitudinal direction is smaller than the width of the central longitudinal beam.

The invention also relates to a method for producing a vehicle, in particular a rail vehicle, having a high-floor area and a low-floor area arranged lower in relation to the high-floor area.

According to the invention, it is provided with respect to such a method that a center-length carrier arranged in the high-floor area and a floor element arranged in the low-floor area are welded directly or indirectly by means of at least one weld seam which extends along or at least also along the vehicle longitudinal direction.

With regard to the advantages of the method according to the invention, reference is made to the above explanations in connection with the vehicle according to the invention, since the advantages essentially correspond. The invention will be explained in more detail with reference to embodiments; thereby show by way of example

Figure 7 shows an embodiment of an inventive

A rail vehicle in which a center-length carrier arranged in the high-floor area and a floor element arranged in the low-floor area do not overlap and are connected to one another by means of an intermediate element, and 8 shows an exemplary embodiment of a rail vehicle according to the invention, in which a center rail arranged in the high-floor area and a floor element arranged in the low-floor area overlap in sections and are welded together directly by means of welds arranged in the longitudinal direction of the rail vehicle or in the longitudinal direction of the central rail.

For the sake of clarity, the same reference numbers are always used in the figures for identical or comparable components.

FIG. 1 shows a rail vehicle 10, which has a high-floor area 11 and a low-floor area 12. In the high-floor area 11 there is a central-length girder 20, which overlaps in sections with a floor element 30 arranged in the low-floor area 12. In the region of the overlap region, an intermediate element 40 is arranged, which is welded to both the center-length carrier 20 and to the bottom element 30. The weld seams for connecting the center-length beam 20 to the intermediate element 40 extend along the longitudinal direction L of the rail vehicle 10 and are identified by the reference numeral 100 in FIG.

The connection between the intermediate element 40 and the bottom element 30 is likewise based on weld seams which extend along the longitudinal direction L of the rail vehicle 10 and thus along the longitudinal direction of the central longitudinal beam 20; These welds are indicated in the figure 1 by the reference numeral 100. In addition to the high-floor area 11, the rail vehicle 10 may have a further high-floor area 13, which is equipped with a central-length girder 21 and is connected via an intermediate element 41 to the floor element 30 in the low-floor area 12. is bound. The connection of the intermediate element 41 with the bottom element 30 and with the central longitudinal beam 21 likewise takes place via weld seams 100 which extend along the longitudinal direction L of the rail vehicle 10.

FIG. 2 shows a section of the rail vehicle 10 according to FIG. 1 in a three-dimensional view obliquely from the side in a cutaway state. The middle-length carrier 20, which is connected to the base element 30 via the intermediate element 40, can be seen. In addition, the weld seams 100 can be seen, which extend along the longitudinal direction L of the rail vehicle 10 and in each case produce a welded connection between the intermediate element 40 and the center-length beam 20 or between the bottom element 30 and the intermediate element 40.

Moreover, FIG. 2 shows that the center-length carrier 20 is narrower than the distance between a side wall of the rail vehicle 10 marked in FIG. 2 and an opposite side wall of the rail vehicle, not shown in FIG. The distance between the central longitudinal beam 20 and the side wall 15 is bridged in the embodiment of Figure 2, inter alia, by means of an intermediate plate 200. The intermediate plate 200 extends perpendicular to the vehicle longitudinal direction of the rail vehicle 10 and perpendicular to the floor element 30.

For the connection of the intermediate plate 200 four weld seams are provided in the exemplary embodiment according to FIG. 2, which are identified by the reference symbols 201, 202, 203 and 204. The weld seam 201 serves to connect the intermediate plate 200 to the side wall 15. The weld 202 connects the intermediate plate 200 to the bottom element 30. The welded seam 203 serves to connect the intermediate plate 200 to the intermediate element 40. The weld 204 connects the intermediate plate 200 the central longitudinal beam 20. Instead of the four welds shown 201, 202, 203 and 204 can for Tying the intermediate plate 200 and fewer welds, so for example only one, two or three of the welds 201, 202, 203 and 204 are provided. Due to the described arrangement of the intermediate plate 200 in the rail vehicle 10, the four welds 201, 202, 203 and 204 each extend perpendicular to the vehicle longitudinal direction L of the rail vehicle 10. In Figure 2, a further intermediate plate 300 is also recognizable, which is also perpendicular to the vehicle longitudinal direction L of the rail vehicle 10 extends, but not perpendicular to the bottom member 30 is disposed, but transversely thereto. The intermediate plate 300 is preferably also on the side wall 15, on the bottom member 30, on the

Intermediate element 40 and / or welded to the central longitudinal beam 20.

FIG. 3 shows the arrangement of the intermediate element 40 in the overlapping region between the center-length carrier 20 and the bottom element 30 again in a view from the side. It can be seen the welds 100, with which the intermediate member 40 is welded to the central longitudinal beam 20 and with the bottom member 30. The welds 100 extend along the longitudinal direction L of the rail vehicle 10. Incidentally, reference should be made to the above statements in connection with FIG. 2.

With regard to the bottom element 30, it is considered to be advantageous if in the region of the weld seam (s) 100 it has in each case a reinforcement region 31 which extends along the vehicle longitudinal direction L. It is particularly advantageous if the base element 30 is formed by a hollow-chamber profile and the reinforcement region or regions 31 are arranged inside the hollow-chamber profile and are covered by an upper base plate 32 of the hollow-chamber profile. FIG. 4 shows an exemplary embodiment of an intermediate element 40 which is suitable for connecting the center-length carrier 20 to the bottom element 30 in the rail vehicle 10 according to FIG. The intermediate element 40 is formed by an extruded profile part 401 which has side walls 402 and transverse struts or transverse plates 403. The assembly of the intermediate element 40 in the rail vehicle 10 according to FIG. 1 preferably takes place in such a way that the extrusion direction S of the

Extruded section 401 parallel to the vehicle longitudinal direction L of the rail vehicle 10 is located.

FIG. 5 shows two intermediate elements 40 in the form of sheet metal plates 410, which can be used to connect the central longitudinal beam 20 and the floor element 30 in the rail vehicle 10 according to FIG. For reasons of stability, not only a single metal plate 410 or only a single intermediate element 40 is preferably used for connecting the central longitudinal carrier 20 to the bottom element 30, but a plurality of metal plates 410 or a plurality of intermediate elements 40, which can be arranged, for example, parallel to one another.

In addition, FIG. 5 indicates by reference numeral 100, where welding seams for welding the sheet-metal plates 410 to the center-length carrier 20 and the bottom element 30 can be arranged.

FIG. 6 shows an exemplary embodiment of an intermediate element 40 which is formed by a milled part or casting 420.

FIG. 7 shows an exemplary embodiment of a rail vehicle 10, in which the center-length beams 20 and 21, which are arranged in the high-floor area 11 or in the high-floor area 13, do not overlap with the floor element 30. The connection of the non-overlapping center-length carriers 20 and 21 to the bottom element 30 takes place via intermediate elements 40 and 41, which are welded to the center-length carrier 20 or 21 and the bottom element 30. The welds 100 extend along the longitudinal direction L of the rail vehicle 10. Incidentally, reference is made to the above explanations in connection with the figure 1. FIG. 8 shows an exemplary embodiment of a rail vehicle 10, in which two center-length carriers 20 and 21 are welded directly to the bottom element 30. A corresponding direct welding is made possible by a corresponding shaping of the bottom element 30 and / or the middle-long beam 20 or 21. The weld seams for welding the central-length carriers 20 and 21 to the bottom element 30 are identified by the reference numeral 100 in FIG. It can be seen that the welds 100 extend along the longitudinal direction L of the rail vehicle 10.

The use described above in detail of welds 100, which extend along the longitudinal direction L of the rail vehicle 10, may u for. a. one or more of the following advantages: - simplified tolerance compensation in the longitudinal direction, since the connection is made via longitudinal seams,

simplified tolerance compensation in the transverse direction, since instead of profiles only sheet metal can be adjusted here, lower production costs due to the described simplified tolerance compensation,

lower material costs, since fewer hollow profiles are necessary,

Creation of additional installation space for other components, as the areas between the center-length beam and the side wall can be closed with intermediate plates due to the lower power flow.

While the invention has been further illustrated and described in detail by way of preferred embodiments, the invention is not limited by the disclosed examples, and other variations can be derived therefrom by those skilled in the art without departing from the scope of the invention.
