Definitions

  • the present invention relates to a vehicle with a vehicle body structure, in particular a rail vehicle.
  • Vehicles in particular rail vehicles, typically have a vehicle body structure comprising two side walls extending on the longitudinal sides of the vehicle, two transversely extending end walls, namely a front end wall and a rear end wall, a vehicle floor and a vehicle roof.
  • the side walls comprise, for static reasons, each an upper and a lower longitudinal beam and each a side wall panel.
  • braces are often provided on these in order to absorb compressive and tensile forces in different operating situations can, for example when lifting and railing of the vehicle, aerodynamic loads or even increased buffer pressure.
  • a structure which has a base frame with a first and a second longitudinal beam.
  • the side wall is formed in part by a side wall panel, an outer and an inner support post, which are connected to the side wall panel and disposed at the ends adjacent to the longitudinal beams.
  • the car body structure of a freight car with a base and side walls specified.
  • the side walls are formed of several side panels and support posts.
  • the support posts are attached to the side panels by means of self-cutting rivets.
  • one or more wells may be molded into the side wall panels, respectively. These hollows are located in the area of the support posts.
  • four or five such wells may be incorporated in a row in the side panel extending to near the top sidewall edge and near the bottom sidewall edge.
  • a car body structure of a freight car is disclosed.
  • the carbody structure includes side walls with spaced apart vertical support posts and with horizontal stiffening elements secured between the support posts.
  • the horizontal stiffening elements form a recessed sidewall profile.
  • the side wall construction is formed by welded together side panels, side lower straps and upper longitudinal straps.
  • the welded side panels form stiffeners in the form of ribs.
  • the lower side straps are formed by a vertical rib, a lower inwardly curved belt and an elbow fixed to the upper edge of the rib.
  • the upper longitudinal straps are T-shaped with a vertical rib and an upper horizontal plate.
  • US 2010/0011987 A1 indicates a vehicle body for an open railroad car. Its side walls have upper and long sleepers and vertical posts with different cross-section.
  • the long sleepers are formed by rectangular steel tubes.
  • the vertical posts can have a constant hollow cross-section, the seam transition is connected by welding to the wall.
  • EP 1 935 743 A1 discloses a railway freight wagon with lateral sliding walls having a vertical lower and an inwardly angled, upper side wall part exhibit.
  • the lower side wall part is formed by a lower sheet steel field, which is bordered at the lower longitudinal edge by a lower longitudinal steel profile and at the upper longitudinal edge by an upper steel Eckholmprofil.
  • the steel profiles are designed as open profiles.
  • steel transverse profiles are fastened within the sheet metal fields, which are designed in the form of hat profiles.
  • the car body structures of the known rail vehicles are complex, so that their production is costly.
  • conventional car body structures consist of a plurality of individual components, such as struts, stiffening posts, Beulsteifen, covers and the like, with which, for example, a framework can be formed and welded together with the wall elements, so that there is a considerable installation effort.
  • the long beams of the side walls are also mounted by welding only with difficulty because the joints are often not easily accessible.
  • the car body structure must meet the static requirements of the load bearing and load distribution in various operating situations, such as lifting and railing of the vehicle, aerodynamic stress and force on the vehicle via the buffers.
  • the invention has the object to find a vehicle with a vehicle body structure, which is easy and therefore inexpensive to produce, which has a pleasing appearance and which meets the static requirements of the load bearing and load distribution.
  • the vehicle according to the invention has a vehicle box structure which comprises two side walls extending on the longitudinal sides of the vehicle.
  • the side walls each have an upper and a lower longitudinal beam and in each case a side wall plate.
  • each side wall panel for stiffening at least one long depression extending vertically from the lower longitudinal member to the upper longitudinal member is introduced.
  • the side panel is preferably connected to the long beams in the area of the long hollows.
  • the side panel provided with the at least one long trough preferably extends over the entire length of the vehicle, or at least the length of the vehicle part, which is not occupied by a driver's compartment / cabs, namely over the length of the engine room of the vehicle.
  • the side wall of the vehicle is preferably formed by a single side wall panel having at least one long trough.
  • the upper longitudinal beam and the lower longitudinal beam are each in the form of at least one web plate or a rectangular hollow profile and formed on longitudinal edges of the at least one web plate or rectangular hollow profile with this connected upper straps and lower straps I-beam.
  • the lower long beam may have a wider web plate for reasons of static than the upper I-beam.
  • the I-beam of the lower long beam and / or the upper long beam may alternatively be formed of a web plate with two serving as upper and lower belt rectangular hollow sections.
  • the car body structure of the vehicle according to the invention is much simpler, easier and therefore less expensive to produce and assemble than previously known car body structures. Because compared to conventional car body structures, the car body of the vehicle according to the invention consists of only a few components that are connected to the side wall panel. By eliminating the additional involvement of stiffening ribs, struts, posts, Beulsteifen and covers in the region of the side wall panel, can be formed without further effort only interrupted by the long hollows flat side wall surface, so that an attractive appearance of the vehicle is achieved.
  • the vehicle body structure according to the invention is therefore a robotic, fault-tolerant welded construction with a greatly simplified geometry for the longitudinal beams and the side wall panel.
  • the examination of the manufactured joint connections is considerably simplified. For example, an endoscope is not required.
  • the side wall panels By introducing at least one longitudinal recess extending substantially perpendicularly from the lower longitudinal member to the upper longitudinal member in the side wall panels, which are preferably also connected to the longitudinal members in the region of the long recesses, excellent rigidity, in particular flexural stiffness, of the body is achieved.
  • the side panel is by the introduction of the long hollows push and bulge.
  • the vehicle according to the invention is in particular a rail vehicle, especially a railcar.
  • a rail vehicle especially a railcar.
  • this includes a freight car and a locomotive, but also a passenger transport vehicle, such as a tram or a passenger car for local or long-distance traffic to understand.
  • the vehicle typically also includes front elements in addition to the body.
  • the car body is mounted on chassis.
  • the side panel is preferably made of steel.
  • the sheet typically has a thickness of about 4 mm.
  • the sheet may in principle be thicker than 4 mm, for example up to 10 mm, or even thinner, for example up to 1.5 mm.
  • thicker sheets are more difficult to machine and have a greater weight.
  • Thinner sheets are easier to work and have a lower weight.
  • the stability of a thinner side wall panel is reduced.
  • the cross section of at least one long recess in the side wall panel is rectangular, possibly also square, or trapezoidal. Thus, a U-profile is formed in these cases.
  • the cross-section may also have a "hat shape", ie, further legs may adjoin the side legs of the profile (the "brim"), which preferably lie flat against a joining connection on the long beam. It is preferable to choose a cross section that satisfies the requirements of the statics of the car body.
  • minimum dimensions for the depth of the profile (distance between the tread base and the side wall surface) and the width of the tread (distance of the tread legs at the transition to the side wall surface) shall be chosen, for example a depth of at least 20 mm (and not more than 100 mm), and, for example, a width that is at least 2 times (and preferably at most 15 times) the depth.
  • the long trough can also have a triangular cross-section. The cross section of the long trough preferably remains substantially constant over its entire length.
  • each long recess in the side wall plate is produced by bending.
  • the side panel is very gentle, i. with virtually constant sheet thickness, generated, and there are no disturbances in the metal structure, such as microcracks caused.
  • the long depressions are produced by means of a forming process, for example by deep-drawing, the material can flow, with the result that the thickness of the side wall is differently thick at different points.
  • microcracks can be formed. This affects the strength of the material.
  • a very important advantage of the production method by folding is that no special forms for forming must be provided. Rather, it is sufficient that the long hollows are produced on a conventional press brake.
  • each long recess is formed as a bulge of the side wall panel to the vehicle outer side.
  • the long troughs can in principle be designed as a bulge of the side wall panel to the vehicle interior.
  • At least three long depressions may also be introduced into each side panel for static reasons, with the distances between adjacent elongated troughs being equal or at least essentially ( ⁇ 20%) equal, resulting in a uniform stress distribution in the side wall.
  • Such components may for example be installed in the region of the side wall panel, preferably welded to form, for example, a framework.
  • Such additional stiffening may be required, inter alia, when openings, such as ventilation openings, or bushings in the side wall panel must be provided. The power flow in the side wall must then be passed around these openings or passages around them.
  • the side wall panel is connected to the upper and the lower longitudinal beams by welding.
  • the side wall plate is welded to the long beams in the area of long hollows.
  • the side panel may also be connected to the longitudinal members by other joining techniques, for example by riveting.
  • the material from which the long beams are formed in the form of I-beams may have a thickness of about 10 mm. This thickness gives the I-beam sufficient bending and torsional rigidity. Of course, the material may also be thicker, for example up to 25 mm, or even thinner, for example up to 4 mm. However, the rigidity is reduced with thinner sheets, and the processability of the material is difficult in the case of thicker material. In addition, the weight of the I-beams is higher when the material is thicker.
  • the long beams are preferably made of steel.
  • a tensile or compressive force acting on the vehicle over the lower longitudinal girder to be transmitted from the bottom to the top in a substantially rectilinear manner (viewed in cross section in or opposite to the transport direction) via the side wall panel onto the upper elongated girder.
  • the web plate of the lower long beam, the parts of the side panel, not the long but the flat, albeit interrupted by the long hollows form wall surface, and the web plate of the upper long beam are aligned substantially aligned with each other.
  • the present invention over the known constructions advantageous (see, for example, the non-aligned arrangement of the lower outer longitudinal member, the side wall panel and the upper flange in the side wall construction, which in WO 2009/114793 A1 is shown).
  • the upper longitudinal member and / or the lower longitudinal member is stiffened by at least one U-profile connected to the web plate and the upper flange and the lower flange and extending vertically.
  • Each such U-profile of the upper and lower longitudinal beam is preferably connected thereto by welding.
  • the U-profiles can also be connected by a different joining method with the longitudinal beams, for example, rivets.
  • each U-profile of the upper or lower longitudinal beam is aligned with a long recess in the side wall panel.
  • the longitudinal beams and the side wall plate and optionally other components are preferably made of steel. But they can also consist of aluminum.
  • the side walls may also be covered by tarpaulins to provide an aesthetically pleasing appearance of the side walls
  • each side wall can be laminated by a tarpaulin.
  • a large-format motif may be appropriate, such as advertising, a company logo or the like.
  • the tarpaulin can be fastened to the side wall by means of a fastening device.
  • the tarpaulin for attaching it to the sidewall at at least one edge has a welt, i. an edge reinforcement of the tarpaulin, on.
  • fastening devices are provided on the side wall, which hold the tarpaulin at their edges. Over at least one edge, preferably over three edges, the tarpaulin is stretched.
  • each fastening device can have a holding device, for example in the form of a retaining profiled rail, for example with a respective guide chamber for receiving the welt of the tarpaulin. If the tarpaulin with the respective fastening device is also tensioned, this additionally has, assigned to each holding device, in particular retaining profiled rail, at least one clamping device attached to the vehicle for exerting a force on the holding device, in particular retaining profiled rail, on the tarpaulin.
  • the clamping device may have an adjusting device, such as a bolt which engages in a thread and over which the holding device, in particular retaining rail, held and thus the tarpaulin can be stretched.
  • the piping of the tarpaulin is received in the guide chamber of the holding device, preferably by lateral insertion of the welt in the guide chamber.
  • the flag of the welt or the tarpaulin protrude through a slot out of the guide chamber.
  • the holding device in particular retaining rail, holds the tarpaulin at one edge in this manner, so that the force used to tension the tarpaulin is uniformly transmitted across the wall to the tarpaulin surface and any compressive or tensile load acting on the tarpaulin is uniform over the edge is derived.

  • 22 U-profiles can be made in the side wall by folding.
  • the U-profiles 115 are produced by folding. They each result bulges of the side wall to the vehicle outer side (in principle, the U-profiles can also bulges to the vehicle inside revealed). These U-profiles each have side legs 116, 117 and an end face (a profile bottom) 118.
  • the U-profiles have, for example, a depth (bulging of the flat side wall surface 111) of about 2 cm and a width (parallel to the flat side wall surface) of about 8 cm.
  • the center distance between adjacent U-profiles is about 50 cm, so that the free area 111 between the U-profiles is about 43 cm wide.
