  • the invention relates to a vehicle body component according to the preamble of claims 1 and 2, as is known for example from DE 198 24 932 AI.
  • Hybrid components consist of several individual parts made of different materials that are joined together using joining processes. By using such hybrid components, considerable weight savings can be achieved, for example in body construction.
  • the material properties of the individual parts are matched to one another in such a way that on the one hand the strength and rigidity requirements placed on the component are satisfied, while on the other hand the lowest possible weight of the overall component is realized.
  • hybrid components are used in vehicle construction, which have a body shell made of a lightweight metallic material (e.g. aluminum) and are provided with a reinforcing element made of a steel material to achieve the required strength and rigidity properties.
  • the outer skin part consist of a steel sheet, while the reinforcing element is made of a light metal alloy.
  • DE 199 39 977 AI proposes to connect the two individual components of the hybrid component to one another using an additional element in such a way that the additional element is rebated in a first fastening section with the light metal individual component and in another Fastening section is connected to the individual steel component by a non-thermal connection technology; this is intended to achieve a particularly low-stress joint connection of the two individual elements, which in turn should result in a smooth external appearance of the hybrid component after painting.
  • the design of the connection area of the two individual elements used is very complex and expensive, since an additional element is necessary and several different joining methods are used.
  • the invention has for its object to develop the hybrid component known from DE 198 24 932 AI in such a way that it can be installed in a vehicle body - free of the risk of deformation due to heat treatments described above.
  • the production of the hybrid component from the individual parts should be able to be accomplished with the aid of simple joining processes and should not require any additional elements.

  • the layers of lacquer which are applied to the individual elements according to the invention prior to joining advantageously include all those surface coating and coating processes which are associated with a heat treatment. In automotive engineering, this applies, for example, to cathodic dip coating (KTL), in which the painted parts are typically heated to approx. 190 ° C for approx. 30 minutes, and / or the top coat with the subsequent penetration, in which the coated parts are typically used for approx Are heated to about 155 ° C for 30 minutes.

  • the individual elements are provided with the layers of lacquer whose application is accompanied by a sharp change in the temperature of the surface to be painted, painting steps no longer need to be carried out on the finished hybrid component. Due to the temporal shift of these painting steps according to the invention to a point in time before the joining of the individual parts, the heat treatment of the joined hybrid component, which is associated with these painting steps, is omitted. In this way, the thermal load on the hybrid component can be significantly reduced, whereby a considerable reduction in the deformation of the hybrid parts can be achieved. Special advantages brings the inventive design of the hybrid component when the individual elements consist of materials with very different coefficients of thermal expansion, such as steel and aluminum.
  • the hybrid component consists of at least two individual elements made of different metallic materials.
  • the hybrid component is advantageously a body component, the individual elements of which - for example by deep drawing - are produced from metal sheets.

  • the hybrid component comprises a structural component made of steel, which is provided with a plastic trim part. All online-compatible plastics used in the automotive industry, in particular polymers, SMC, fiber-reinforced plastics, etc. can be used as materials for the plastic part.
  • the individual elements are advantageously connected to one another with the aid of an adhesive process.
  • a 2-component adhesive is used for this purpose, which cures at room temperature (and can be selected so that it simultaneously acts as corrosion protection).
  • the individual elements can be connected by punch rivets;
  • the joining areas are advantageously placed and designed such that the joining areas on the finished body are covered by a decorative strip or the like.

Abstract

L'invention concerne un composant hybride (1) comprenant deux éléments individuels (2, 3) constitués de différents matériaux métalliques. L'invention concerne également un composant hybride qui est composé, au moins en partie, d'un matériau synthétique. L'objectif de l'invention est de minimiser la déformation thermique du composant hybride (1) apparaissant lors du traitement de surface et/ou du fini de surface. A cet effet, au moins un des éléments individuels (2, 3) est doté d'un revêtement ou d'un fini (4, 5) souhaité, avant d'être assemblés, tout en éliminant la nécessité d'un traitement de la surface chargé thermiquement du composant hybride (1).
