Definitions

  • the invention relates to a roof structure for a car body for a rail vehicle.
  • the roof structure of a rail vehicle must therefore have the necessary rigidity and strength to withstand the forces that occur during operation and maintenance of the vehicle.
  • the roof structure must meet weight restrictions in order to avoid an unnecessarily high weight of the rail vehicle.
  • the object of the invention is to provide an improved roof construction for a rail vehicle.
  • a roof structure for a car body for a rail vehicle is provided with two roof rails and a roof assembly, each roof rail being connectable to a side wall assembly of a car body of the rail vehicle, the roof rails being set up to close the roof assembly with the side wall assemblies of the car body connect, wherein each roof rail has a carrier support running along a longitudinal direction of the roof rail, wherein the roof assembly comprises fixing pads arranged on longitudinal sides of the roof assembly and extending in a longitudinal direction of the roof assembly, and wherein the roof assembly is formed by placing the fixing pads on the carrier pads and is fixed to the roof rails via a welded connection between the fixing supports and the support supports.
  • an improved roof construction can be provided for a car body of a rail vehicle.
  • the support supports of the two roof rails and the fixing supports of the roof assembly can be used to easily connect the roof assembly to the roof rails by positioning or placing the fixing supports of the roof assembly on the support supports of the two roof rails and a welded connection between the fixing supports of the roof assembly that rest on one another and the Carrier conditions of the two roof rails of the roof construction are effected.
  • a planar fixation of the roof assembly to the roof rails can be achieved by resting the fixing supports on the carrier supports and partially covering the carrier supports of the roof rails by the fixing supports of the roof assembly be reached.
  • a planar connection between the roof rails and the roof assembly can be achieved, which extends along the longitudinal direction of the roof rail and along the longitudinal direction of the roof assembly. Due to the surface connection, a uniform force distribution can be achieved from the roof assembly to the roof rails arranged laterally to the roof assembly.
  • the roof construction due to the planar connection of the roof assembly with the roof rails via the support supports of the roof rails and fixing supports of the roof assembly that rest on one another, the roof construction, especially in connection with the side wall assemblies of the car body, is not provided with ring frames in which a direct power transmission between stiffening structures of the side wall groups and cross braces of the roof assembly are provided. Due to the surface connection of the roof assembly with the roof rails via the carrier supports and fixing supports and the resulting uniform force transmission between the roof assembly and the roof rails, there is no need for cross braces of the roof assembly to be arranged on the roof assembly in such a way that direct force transmission from the cross braces the roof assembly is enabled on stiffening structures of the side wall assemblies of the car body or on the roof rails.
  • the cross braces can be arranged at any position on the roof assembly that is optimized for increasing the rigidity of the roof assembly without having to pay attention to direct contact of the cross braces with stiffening structures of the side wall assemblies when positioning the cross braces. Due to the flat contact of the fixing supports of the roof assembly on the support supports of the roof rails, a flat or continuous welded connection can also be produced between the fixing supports of the roof assembly and the support supports of the roof rails, whereby a robust and durable connection of the roof assembly with the roof rails can be achieved.
  • the weld is a laser weld, a spot weld, or a MAG weld.
  • the technical advantage can be achieved that a robust and resistant connection of the roof assembly to the roof rails is made possible.
  • the support supports of the roof rails and/or the fixing supports of the roof assembly each have a planar support surface.
  • the technical advantage can be achieved that a flat contact of the fixing supports of the roof assembly on the carrier supports of the roof rails and associated a robust connection and a uniform power transmission between the roof assembly and the roof rails is made possible.
  • the supports of the longitudinal roof supports and/or the fixing supports of the roof assembly are each designed as a support plate and are elastically deformable.
  • a transversely flexible connection of the roof assembly to the roof rails can be achieved due to the elastic deformability of the carrier supports of the roof rails or fixing supports of the roof assembly designed as a support surface.
  • the flexible or transversely soft connection enables the roof assembly to be flexible relative to the roof rails. This can improve the durability of the connection while maintaining the strength of the connection between the roof assembly and the roof rails.
  • the roof rails each have a plurality of support ribs arranged next to one another in the longitudinal direction of the roof rail, the fixing supports being connected to the support ribs.
  • the technical advantage can be achieved that when the roof assembly is fixed to the side wall assemblies of the car body, a uniform and effective transmission of force from the roof assembly via the roof rails into the side wall assemblies can take place via the plurality of support ribs.
  • the support supports are each designed as an L-shaped support plate with a planar support surface and a fastening surface arranged at an angle to the planar support surface, the support supports being fastened to the respective roof longitudinal beam via the fastening surfaces, and the planar support surfaces of the support supports in protrude from the respective roof rail at an angle to the longitudinal direction of the roof rail.
  • the technical advantage can be achieved that the carrier supports of the longitudinal roof carrier can be provided in a structure that is technically easy to manufacture.
  • a solid fixation of the carrier supports on the roof rails can be effected.
  • the fixation supports are each formed as a planar edge area on a longitudinal side of the roof assembly.
  • fixation supports that are easy to manufacture can be provided.
  • the fixing supports are designed as planar edge regions on the longitudinal sides of the roof assembly, which is manufactured as a metal sheet or plate.
  • the roof assembly has at least one cross brace running along a transverse direction of the roof assembly, the at least one cross brace ending at a predetermined distance from the fixing support.
  • the technical advantage can be achieved that structural strength of the roof assembly via the cross brace can be improved. Due to the distance between the cross brace and the fixing support, it can be achieved that the cross brace does not come into contact with the roof rails. In this way, a uniform transmission of force between the roof assembly and the roof rails can be achieved, which is effected exclusively via the fixing supports of the roof assembly resting on one another and the carrier supports of the roof rails. Since the cross braces have no direct connection to the roof rails, there is no point-by-point increase in the force transmission on the roof rails, which could occur if the cross braces came into direct contact with the roof rails.
  • the roof assembly has at least one longitudinal strut running in the longitudinal direction of the roof assembly, the longitudinal strut being arranged between the fixing support and the transverse strut and delimiting the fixing support in the transverse direction of the roof assembly.
  • the technical advantage can be achieved that positioning of the roof assembly on the roof rails is facilitated in that in particular a displacement of the roof assembly along the transverse direction of the roof assembly relative to the roof rails is limited by the longitudinal struts fixed to an underside of the roof assembly. In this way, the assembly or positioning of the roof assembly on the roof rails can be facilitated.
  • the roof assembly with the fixing supports resting on the support supports before welding is displaceable along the longitudinal direction of the roof rail and/or along the transverse direction of the roof rail and can be positioned in at least two different positions relative to the roof rail.
  • the technical advantage can be achieved that along the slidability of the roof assembly Longitudinal and transverse directions of the roof assembly relative to the roof rails further facilitates the positioning of the roof assembly on the roof rails. Because the roof assembly can be positioned in different positions in the longitudinal or transverse direction relative to the longitudinal roof members, in which the fixing supports rest on the carrier supports of the longitudinal roof members, manufacturing tolerances of the car body or the longitudinal roof member or the roof assembly can be compensated. This in turn can facilitate assembly of the construction.
