Definitions

  • the present invention relates to a shell according to the preamble of claim 1.
  • an external metal sheet which is provided on internal beams in order to increase the stiffness of the metal sheet is used.
  • supporting elements are provided which are connected to the sheet by means of welding.
  • a ventilation layer is provided in connection with the sheet and a thermal insulating layer and finally an internal panel.
  • DE 296 08 643 U1 shows a structural element which comprises a portion of a side wall, a roof and a floor of a railway vehicle.
  • the structural element comprises external and internal layers formed by a fibre reinforced plastic material. Said external and internal layers are connected to each other along the edges of the structural element, wherein they enclose an intermediate layer.
  • This structural element comprises longitudinal reinforcement beams at the roof and floor portion of the structural element. Such reinforcement beams lead also in this case to a relatively complicated construction of the structural element. Furthermore, it may be difficult to obtain a completely even and smooth external surface in a fibre reinforced plastic material.
  • US 5,784,970 refers to a carriage body frame for rail vehicle, which comprises load-bearing sections in the form of roof struts of aluminium and light-weight composite panels, inserted between the load-bearing sections.
  • the light-weight composite panels consist of a core surrounded by aluminium sheets, which are connected to the core by an adhesive.
  • the light-weight composite panels comprise surrounding connecting sections.
  • the object of this structure is to provide a carriage body frame, which has low weight, high rigidity and good long term strength properties.
  • the stiffness of the carriage body frame is mainly (not to say nearly fully) provided by the load-bearing sections, not by the light-weight composite panels, which correspond to the structural element in present application.
  • the purpose of the light-weight composite panels is to reduce the weight of the carriage body frame.
  • EP 0 375 621 refers to a tiltable hutch container of a road or rail vehicle.
  • the hutch container consists of a floor plate, wall plates and a roof plate. Each plate comprises a core layer surrounded by sheets of aluminium.
  • the plates may be connected to each other by means of an upper profile and a lower profile. Adhesive connections may be used for connecting the plates to the profiles.
  • EP 0 354 436 shows a car body of a railway vehicle, which comprises composite panels.
  • the composite panels comprise a core and surrounding layers, which may be of aluminium.
  • the main structural strength (stiffness) of the carbody are provided by framing profiles, whereas the composite panels mainly are used to fill up the space between the framing profiles.
  • the object of the present invention is to provide a shell of the initially mentioned kind, which is inexpensive to manufacture and which has external and internal surfaces of high quality at the same time as it enables a rapid and uncomplicated mounting in the vehicle.
  • the structural element does not require through beams or surrounding reinforcement beams, wherein the manufacturing of the structural element is considerably simplified.
  • Such a structural element may also be manufactured to a low cost at the same time as it may be made essentially lighter with respect to weight than by prior art technique.
  • the structural element comprises an intermediate layer of a thermal insulating material. Thereby is obtained that no further thermal insulation need to be provided internally in the vehicle.
  • a wall construction may thereby be manufactured essentially thinner than by a conventional construction and encroaches thereby less on the internal volume of the vehicle.
  • the internal layer comprises a metal material.
  • a metal material may be steel or aluminium.
  • both the external and internal layer comprise sheets of metal which in co-operation with the intermediate layer forms a structural element with such a stiffness that it may constitute a supporting component of a vehicle body.
  • the external layer may comprise a metal material. Thereby, the external layer will be dimensioned so that it will carry the main load of the structural element but it will at the same time be propped and guyed by the remaining layers so that the structural element without problem may be used as a supporting component.
  • said intermediate layer is substantially thicker than said internal and external layers.
  • the intermediate layer comprises such a stiff material that it supplies stiffness to said structural element.
  • Such a stiff intermediate layer prevents also in an effective way that buckles and deformations occur in the relatively thin external and internal layers. Consequently, such an intermediate layer has two functions, namely to stiffen the external and internal layers as well as to provide thermal insulation.
  • said intermediate layer is fixedly connected to the internal and external layers by means of a binder means in the form of an adhesive arranged to work so that said layers are connected over substantially its entire surface.
  • a binder means in the form of an adhesive arranged to work so that said layers are connected over substantially its entire surface.
  • the external and internal layers of said structurraf element comprise at least a curved portion.
  • a shell of a vehicle is manufactured with curved portions in order to, for example, decrease the air resistance of the vehicle and to use available loading profile to obtain an aesthetically attractive visual sensation.
  • a structural element according to the present invention which does not comprise stiffening beams, may in a rather uncomplicated way be manufactured with curved surface portions but may also be performed with a plane surface.
  • Said relatively thin external and internal layers may without problem each be bent to a desired shape individually or during the joining process with the intermediate layer.
  • the intermediate layer may with a suitable choice of material also without problem be manufactured in a desired shape, wherein such a material may be a plastic material.
  • said layers are connected with a suitable adhesive in order to form a structural element, which has desired curved surfaces.
  • the structural element comprises fastening devices for equipment in the vehicle. Since the internal layer of the structural element has a flat surface, which also may carry loads, the possibility arises to fasten in the vehicle provided internal equipment in the structural element. For example, fasting channels for seats may be provided in the structural element, such channels may be fastened in the internal layer or provided so that they also extend into the intermediate layer- Further material savings are thereby obtained since there is no need for supporting elements, for such equipment.
  • said structural element forms at least a portion of a side wall or a portion of a roof of a car body of a railway vehicle.
  • the present structural element is very favourable to use in railway vehicles such as in underground railway cars and in railway cars for transportation of people. It is in the first place the side walls of the car body, which are suitable to be comprised by said structural element. By making the walls thinner a greater internal volume for the accommodation of passengers may be obtained.
  • the vehicle car will also be essentially lighter, which fact, i.a., influences the energy consumption in a favourable way. It also favorable to use the present structural element in the roof of the car body, which by this measure obtains a light and uncomplicated construction.
  • To use the structural element in a floor construction of a railway vehicle is also an alternative, which may not be excluded.
  • Fig 1 shows a car body 1 of a railway vehicle, comprising a structural element 2 according to the present invention.
  • the structural element 2 forms at least a part of a side wall of the car body 1 and has openings for windows 3.
  • the structural element 2 may, for example, extend between two door openings 4, of which one door opening 4 is shown in Fig 1.
  • the structural element 2 comprises an external layer 5 of a first piece of material comprising a metal material, an intermediate layer 6 of another second piece of material comprising a thermal insulating material, and an internal layer 7 of a third piece of material.
  • the intermediate layer 6 is arranged to be joined together with the external 5 and the internal 7 layers by means of an adhesive so that the three pieces of material form a structural element 2 in one piece.
  • This structural element 2 is intended to be mounted on the vehicle by means of fastening means, which may be applied to suitable portions of the structural element 2.
  • the fastening means which may, for example, be rivet joint connections or joint bolt connections, may thereby connect the structural element 2 at the top to the roof of the railway vehicle and at the bottom to a lower frame 9. Possibly, also fastening means may be applied for connecting the structural element 2 to adjacent side walls.
  • fastening devices for internal equipment may be attached to the structural element 2.
  • Such a mounting of, for example, interior details is considerably simpler to perform before the structural element is mounted to the vehicle since a mounting inside the vehicle always leads to a limited mounting space.
  • Equipment, which may be fixed to the structural element 2 internally, is, for example, fastening channels for seats and sound absorbing panels.
  • Fig 2 shows schematically a cross sectional view of a structural element 2 according to the present invention.
  • the structural element 2 thus comprises an external layer 5, an intermediate layer 6 and an internal layer 7.
  • the external 5 and internal 7 layers consist of metal sheets of, for example, steel or aluminium, which layers essentially supply the supporting properties to the structural element 2.
  • the internal 7 layer may also be performed in a more pliant material, such as plywood, under the condition that the external 5 layer is manufactured in an essentially stiffer material, such as for example, steel.
  • the intermediate layer 6 consists of a stiff, thermal insulating material.
  • Such a material may comprise a foam plastic material of PVC, PMI, PEl or PUR.
  • Alternative materials for the intermediate layer 6 are balsa wood and other materials having good thermal insulating properties.
  • thermal insulating materials may be formed in a honey comb structure.
  • the intermediate layer 6, which is substantially thicker than the external 5 and internal 7 layers, is arranged to provide both stiffness and thermal and sound insulating properties to the structural element 2.
  • the material of intermediate layer 6 may be in full view or covered by, for example, a plastic material 10, in order to protect the material of the intermediate layer 6 against, for example, damp.
