Description
Technisches Gebiet (Technical Field)Technical Field
Die Erfindung betrifft einen Federbeindom umfassend eine Hauptstruktur mit einer Außenseite und einer Innenseite und eine Verstärkungsstruktur, welche lokal mit der Hauptstruktur verbunden ist.The invention relates to a strut dome comprising a main structure with an outside and an inside and a reinforcement structure which is locally connected to the main structure.
Technischer Hintergrund (Background Art)Technical Background (Background Art)
Federbeindome sind im Bereich des Vorderwagens bei Fahrzeugen, insbesondere bei Personenfahrzeugen, bekannt, welche jeweils links und rechts vor der Fahrgastzelle zur Aufnahme der Federbeine des vorderen Fahrwerks angeordnet sind. Beispielhaft ist in der Offenlegungsschrift
Insbesondere mit Blick auf die Reduzierung des Fahrzeuggewichts und damit verbunden die Reduzierung des CO2-Ausstoßes erhalten immer festere Werkstoffe in Verbindung mit reduzierten Wanddicken Einzug in den Automobilbau. Der Reduzierung der Wanddicke sind bei komplex geformten Komponenten, wie zum Beispiel bei einem Federbeindom, welcher dreidimensional insbesondere aus einem Blechmaterial einstückig komplex geformt sein kann, Grenzen gesetzt, da sie bei Unterschreiten einer Mindestwanddicke in manchen Bereichen keine ausreichende Betriebsfestigkeit und Steifigkeit aufweisen.Particularly with a view to reducing vehicle weight and the associated reduction in CO 2 emissions, increasingly stronger materials in connection with reduced wall thicknesses are finding their way into automobile construction. There are limits to the reduction in wall thickness in the case of components with complex shapes, such as a strut dome, which can be formed in a complex three-dimensional manner, in particular from sheet metal material, because if the wall thickness falls below a minimum, in some areas they do not have sufficient operational strength and rigidity.
Zusammenfassung der Erfindung (Summary of Invention)Summary of Invention
Der Erfindung liegt somit die Aufgabe zu Grunde, ein Federbeindom anzugeben, welcher leicht und kostengünstig ist und eine ausreichende Betriebsfestigkeit und Steifigkeit aufweist.The invention is therefore based on the object of specifying a strut dome which is light and inexpensive and has sufficient operational strength and rigidity.
Gelöst wird diese Aufgabe durch einen Federbeindom mit den Merkmalen des Patentanspruchs 1.This object is achieved by a strut dome with the features of
Erfindungsgemäß wird vorgeschlagen, dass die Hauptstruktur ein Blechmaterial und eine mit dem Blechmaterial stoffschlüssig verbundene Polymerschicht umfasst, wobei die Polymerschicht zumindest in dem Bereich vorgesehen ist, in welchem die Hauptstruktur mit der Verstärkungsstruktur verbunden ist, wobei zumindest eine stoffschlüssige Verbindung zwischen Polymerschicht und Verstärkungsstruktur vorliegt.According to the invention, it is proposed that the main structure comprises a sheet metal material and a polymer layer bonded to the sheet metal material, the polymer layer being provided at least in the area in which the main structure is connected to the reinforcement structure, with at least one material connection between the polymer layer and the reinforcement structure.

Es können auch ein oder mehrere Merkmale aus den unabhängigen Ansprüchen durch ein oder mehrere andere Merkmale verknüpft werden.Further advantageous configurations and developments emerge from the following description. One or more features from the claims, the description and also the drawing can be combined with one or more other features from them to form further embodiments of the invention. One or more features from the independent claims can also be linked by one or more other features.
Gemäß einer Ausgestaltung der Erfindung besteht die Verstärkungsstruktur aus einem Kunststoff. Der Kunststoff kann auch verstärkt sein, beispielsweise mit Kurz- und/oder Langfasern. Bevorzugt ist die Verstärkungsstruktur aus Kunststoff angespritzt, so dass die Verstärkungsstruktur bedarfsgerecht auf der Hauptstruktur des Federbeindoms, zumindest auf einer Seite der Hauptstruktur, vorzugsweise aus der Außenseite der Hauptstruktur, anordenbar ist. Die Verstärkung auf der Außenseite hat den Vorteil, dass der Ausbildung der Struktur, sprich der Ausführung der zu erstellenden Geometrie weniger Grenzen gesetzt sind, als im Vergleich zu einer Anordnung auf der Innenseite der Hauptstruktur, welche dem Bereich der Aufnahme des Federbeins zugewandt ist und dadurch wenig bis gar kein Bauraum zur Verfügung steht. Alternativ kann auch ein Kunststoff bereitgestellt werden, welcher beispielsweise in fester Form nach Bedarf bearbeitbar bzw. formbar und insbesondere mit Fasern verstärkt ist, vorzugsweise in Form eines Organoblechs.According to one embodiment of the invention, the reinforcement structure consists of a plastic. The plastic can also be reinforced, for example with short and / or long fibers. The reinforcement structure is preferably injection-molded from plastic so that the reinforcement structure can be arranged as required on the main structure of the strut dome, at least on one side of the main structure, preferably from the outside of the main structure. The reinforcement on the outside has the advantage that the design of the structure, i.e. the execution of the geometry to be created, are less limited than in comparison to an arrangement on the inside of the main structure, which faces the area of the suspension strut and thus little or no installation space is available. Alternatively, a plastic can also be provided which, for example, can be machined or shaped as required in solid form and, in particular, is reinforced with fibers, preferably in the form of an organic sheet.
Gemäß einer alternativen Ausgestaltung der Erfindung umfasst die Verstärkungsstruktur ein Blechmaterial und eine mit dem Blechmaterial stoffschlüssig verbundene Polymerschicht. Beispielsweise ist die Verstärkungsstruktur als kleine Ausführung zur Hauptstruktur ausgeführt. Das Blechmaterial kann der Verstärkungsstruktur eine gewisse Eigensteifigkeit verleihen und in Kombination mit der Polymerschicht sind die Voraussetzungen zur Anbindung an die Hauptstruktur günstig, so dass zumindest eine stoffschlüssige Verbindung zwischen Polymerschicht der Verstärkungsstruktur und Polymerschicht der Hauptstruktur vorliegt. Insbesondere können die beiden Polymerschichten der Hauptstruktur und der Verstärkungsstruktur die gleiche Zusammensetzung aufweisen.According to an alternative embodiment of the invention, the reinforcement structure comprises a sheet metal material and a polymer layer bonded to the sheet metal material. For example, the reinforcement structure is designed as a small version of the main structure. The sheet metal material can give the reinforcement structure a certain inherent rigidity and, in combination with the polymer layer, the conditions for connection to the main structure are favorable, so that there is at least one material connection between the polymer layer of the reinforcement structure and the polymer layer of the main structure. In particular, the two polymer layers of the main structure and the reinforcement structure can have the same composition.
Gemäß einer Ausgestaltung der Erfindung sind die Hauptstruktur und die lokal mit der Hauptstruktur verbundene Verstärkungsstruktur bereichsweise miteinander verbunden, wobei sie zwischen sich zumindest einen Hohlraum ausbilden. Durch die Ausbildung eines Hohlraums kann die Torsionssteifigkeit des Federbeindoms verbessert werden. Eine weitere Erhöhung der Steifigkeit respektive der Torsionssteifigkeit kann dadurch erreicht werden, wenn der zumindest eine Hohlraum zumindest teilweise, insbesondere vollständig mit einem Material gefüllt ist. Als (Füll-)Material in Frage kommen beispielsweise Materialien, die eine geringere Dichte als das Blechmaterial aufweisen, um das Gewicht des Federbeindoms nicht zu sehr zu erhöhen, wie zum Beispiel Polymere, welche vor der Verbindung zwischen der Verstärkungsstruktur und der Hauptstruktur in den Hohlraum eingebracht oder vor der Verbindung zwischen der Verstärkungsstruktur und der Hauptstruktur an die Polymerschicht der Hauptstruktur oder an die Polymerschicht der Verstärkungsstruktur angebunden wird, welches beispielsweise seine Struktur nicht verändert. Alternativ kann auch ein Polymer eingebracht werden, welches insbesondere durch Wärmeeinwirkung, beispielsweise in einem KTL-Prozess, in seine finale Struktur durch Aktivierung und/oder Aushärtung überführt werden kann.According to one embodiment of the invention, the main structure and the reinforcement structure that is locally connected to the main structure are connected to one another in some areas, forming at least one cavity between them. The torsional rigidity of the strut dome can be improved by forming a cavity. A further increase in rigidity or torsional rigidity can be achieved if the at least one cavity is at least partially, in particular completely, filled with a material. As (fill) material, for example, materials that have a lower density than the sheet metal material in order not to increase the weight of the strut dome too much, such as polymers, which are placed in the cavity before the connection between the reinforcement structure and the main structure introduced or connected to the polymer layer of the main structure or to the polymer layer of the reinforcement structure before the connection between the reinforcement structure and the main structure, which, for example, does not change its structure. Alternatively, a polymer can also be introduced, which can be converted into its final structure by activation and / or curing, in particular by the action of heat, for example in a KTL process.
Gemäß einer Ausgestaltung der Erfindung ist die Verstärkungsstruktur auf der Innenseite der Hauptstruktur angeordnet. Alternativ kann die Verstärkungsstruktur auch auf der Außenseite angeordnet sein.According to one embodiment of the invention, the reinforcement structure is arranged on the inside of the main structure. Alternatively, the reinforcement structure can also be arranged on the outside.
Um den bereits vorliegenden Stoffschluss zwischen der Hauptstruktur und der Verstärkungsstruktur weiter zu verbessern bzw. eine Trennung zwischen Haupt- und Verstärkungsstruktur zu vermeiden, ist gemäß einer Ausgestaltung der Erfindung ein zusätzlicher thermischer Stoffschluss vorgesehen. Der thermische Stoffschluss kann lokal oder abschnittsweise vorgesehen sein, wobei als thermischer Stoffschluss eine Löt- oder Schweißverbindung umgesetzt sein kann.In order to further improve the already existing material connection between the main structure and the reinforcement structure or to avoid a separation between the main and reinforcement structure, an additional thermal material connection is provided according to one embodiment of the invention. The thermal bond can be provided locally or in sections, with a soldered or welded connection being able to be implemented as the thermal bond.
