Definitions

  • the invention relates to a structural component for a chassis frame of a vehicle with at least one flange end for fastening the structural component to the chassis frame, and a storage container.
  • the storage container is connected to the at least one flange end via a connecting element, a connecting area being formed between these elements.
  • this connecting element there is at least one
  • Adhesive connection provided.
  • the invention also relates to a method for producing such a structural component.
  • Chassis frames for vehicles usually have two longitudinal members and several cross members. Typically these are made from steel components.
  • cross members were known which are made from material combinations, for example from steel components and fiber composite laminates.
  • the stresses resulting from the different coefficients of thermal expansion are present in particular when the joining partners are joined entirely or partially with an adhesive joint in addition to the connection by means of a fiber composite laminate.
  • the composite experiences high temperatures for curing over a certain period of time.
  • the laminate hardens and the adhesive fully crosslinks. At this high temperature there is no tension in the structural component formed in this way.
  • stresses form in the boundary layers and in the adhesive layer of the joining partners due to the different coefficients of thermal expansion. As already described, this can lead to disruptions in the transmission of loads and even failure of the entire structural component.
  • the invention is now based on the object of proposing a structural component and a method for its production that allows functional integration and the use of different materials and joining techniques, while avoiding the damage caused by the stresses mentioned.
  • a structural component for a chassis frame of a vehicle has at least one flange end and a storage container.
  • the flange end is designed for fastening the structural component to the chassis frame.

  • Storage container has a convex inner shape and an overall elongated outer contour, so that the two end faces of the shape of the storage container thus formed form the respective ends.
  • the at least one flange end has a flange receptacle which loosely receives the storage container at the end.
  • the device according to the invention consequently has at least one flange receptacle, which is why this formulation is also used synonymously in the following text. Accordingly, the end of the storage container is in the at least one
  • Flange mount inserted, inserted or otherwise placed in it. Only a form fit is achieved, but no force-fit or material connection.
  • the storage container is at least partially along its outer surface with an as
  • Fiber composite laminate executed connecting element envelops, which at least partially surrounds the flange receptacle of the at least one flange end in a connection area.
  • Under fiber composite laminate is a fiber plastic composite made of a
  • Plastic matrix can be understood as bedding compound and reinforcing fibers, in particular carbon fibers, embedded in the bedding compound.
  • the process used for this is usually also referred to as the wet winding process.
  • the at least partial wrapping that is, the wrapping of at least a partial area of the outer surface of the storage container with the reinforcing fibers, is
  • Connecting element formed. It is designed or configured in such a way that when the storage container is inserted into the at least one flange receptacle, it at least partially engages around, in other words, overlaps it. This area in which the overlap or encompassing is achieved is referred to below as the connection area.
  • the connecting element By designing the connecting element as a fiber composite laminate, the design of the shape of the storage container is not limited to circular cylindrical geometries, but can be freely selected.
  • the outer surface of the storage tank can also be completely or partially enveloped by means of the RTM process (abbreviation: Resin Transfer Molding).
  • RTM process abbreviation: Resin Transfer Molding
  • This is a resin injection process in which reinforcing fibers, in particular carbon fibers, are applied and only impregnated afterwards.
  • Plastic matrix made of a thermosetting plastic is used as bedding material, such as polyester, epoxy or phenolic resin, in which reinforcing fibers are in turn embedded.
  • bedding material such as polyester, epoxy or phenolic resin, in which reinforcing fibers are in turn embedded.
  • the fibers used are almost completely utilized can.
  • the fibers are deposited around a shaping core, which corresponds to the winding core of the wet winding process and specifies the shape of the component to be manufactured.
  • the fibers are placed or braided around the shaping core in such a way that they form the contour of the component to be produced, with neither folds nor holes forming in the braid to be produced.
  • the fibers are then injected, for example with an epoxy resin.
  • connection element in particular if no storage container is required, or if the fiber composite laminate is to be manufactured with a constant cross section, is the pultrusion process, i.e. a drawing process for manufacturing the fiber composite laminate.
  • connection area at least one groove for receiving an adhesive is provided on the surface of the at least one flange receptacle facing the connection element.
  • at least one injection opening is made in the connection element, corresponding to the at least one groove. It is therefore provided that at least one injection opening is made in the connection area in the connection element, and at least one groove is also provided in the connection area on the surface of the at least one flange receptacle facing the connection element.
  • the at least one injection opening and the at least one groove should correspond to one another, that is to say they should be arranged such that an adhesive can be introduced into the at least one groove through the at least one injection opening.
  • Several injection openings can also be made in the connecting element, all of which correspond to one and the same groove. There can also be several grooves in one

  • the connecting element is firmly connected, ie glued, to the at least one flange end by means of an adhesive that has been injected through at least one injection opening into at least one groove and cured there.
  • the storage container is indirectly fixed to the flange receptacle at the same time.
  • the storage container is thus arranged in a fixed position in the structural component, but is not directly connected to the flange receptacle, they are indirectly connected via the connecting element and the adhesive connection.
  • the storage container can contract within the space available between the inner surface of the fiber composite laminate and its outer surface when the temperature drops and expand when the temperature increases.
  • the structural component according to the invention and the storage container arranged therein form in their entirety a pressure tank.
  • the storage container should be selected so that it can hold a medium and preferably have at least one opening for introducing and / or removing a medium at at least one of its ends, which opening corresponds to a corresponding opening in the associated flange end.
  • the medium can be pressurized air, but also other gaseous or liquid media.
  • the storage container represents a sealing layer, while the connecting element enveloping the storage container absorbs the pressure loads or the mass loads when the storage element is filled with a medium.
  • the storage container can serve as an envelope core during the production of the structural component when the fiber composite laminate is applied, as will be explained below.
  • the storage container can, for example, made of a plastic material, in particular a thermoplastic, particularly preferably made of polyethylene, polyamide or
  • the flange end of the structural component can be made from one or more lightweight materials, such as aluminum.
  • a very low weight is achieved, so that a structural component according to the invention also has only a low weight in its entirety.
  • installation space can be created that previously had to be found outside the structural component.
  • the structural component has the necessary stability and strength, while at the same time it has a low weight.
  • the inside contour of the flange mount should therefore be shaped in such a way that it corresponds to the outer contour of the storage container to be received and a form fit is brought about when the storage container is positioned, i.e. inserted or plugged into the flange receptacle.
  • the flange receptacle can be designed like a shell, and the outer contour of one end of the storage container can be designed to correspond to it, that is to say, for example, like a cap.
  • the adhesive which is injected through the at least one injection opening into the at least one groove is based on acrylate, epoxy resin and / or based on polyurethane.
  • the adhesive should therefore essentially be formed with acrylates, epoxy resins and / or polyurethane.
  • reactive, two-component acrylate-based adhesives are ideal for bonding metals with coated surfaces and plastics.
  • Epoxy resin adhesives are extremely strong.
  • Polyurethane adhesives are suitable for bonding larger areas of a wide variety of materials, especially for components that are permanently or temporarily exposed to vibrations.

Abstract

L'invention concerne un composant de structure pour un cadre de châssis d'un véhicule, en particulier en forme d'une traverse, dans lequel un réservoir de stockage est intégré et un procédé pour sa fabrication. Selon l'invention, la surface enveloppante du réservoir de stockage est enveloppée au moins partiellement par un élément de connexion, qui est conçu comme un stratifié de composite de fibres, et le composant de structure est en outre collé au moins par zones. Pour la fabrication du composant de structure, au moins une extrémité à bride comprenant une réception de bride et un réservoir de stockage sont préfabriqués. Le réservoir de stockage est reçu de manière lâche par l'au moins une réception de bride et collé à celle-ci. Pour cela il est nécessaire que, dans la zone de connexion dans laquelle la liaison adhésive doit être réalisée, du côté de la réception de bride au moins une rainure pour la réception d'une colle et du côté de l'élément de connexion au moins une ouverture d'injection, qui correspond à la rainure, sont prévues ou introduites. Après l'assemblage de tous les composants, la colle peut être introduite dans l'au moins une rainure par l'au moins une ouverture d'injection et durcie. Cela crée une liaison fixe directe entre extrémité à bride et élément de connexion et, résultant de celle-ci, une connexion fixe indirecte entre réception de bride et réservoir de stockage.
