Abstract
Description
Die Erfindung betrifft eine Verbindungsanordnung zweier Bauteile, von welchem wenigstens eines zumindest überwiegend aus einem Faserverbundwerkstoff ausgebildet ist, sowie ein Verfahren zum Verbinden zweier solcher Bauteile.The invention relates to a connection arrangement of two components, of which at least one is at least predominantly formed from a fiber composite material, and a method for connecting two such components.
Auf Grund der hohen strukturellen und funktionellen Integration moderner im Kraftwagenbau verwendeter Bauteile aus Faserverbundkunststoffen, insbesondere bei im resintransfer-molding-Verfahren hergestellten Bauteilen, ist es oftmals problematisch, diese Bauteile zu verbinden und gleichzeitig einen effektiven Toleranzausgleich zu erzielen. Hierzu sind oft aufwändige Verbindungshilfselemente notwendig, die der durch die Verwendung von Verbundwerkstoffen erzielten Gewichtsersparnis wieder nachteilig entgegenwirken. Alternativ hierzu müssen komplexe Interfaces zwischen den zu verbindenden Bauteilen gestaltet werden, was die Entwicklungs- und Herstellungskosten solcher Bauteile nachteilig erhöht.Due to the high structural and functional integration of modern used in motor vehicle components made of fiber reinforced plastics, especially in resintransfer molding process components, it is often problematic to connect these components and at the same time to achieve an effective tolerance compensation. For this, complex auxiliary connection elements are often necessary, which counteract the weight savings achieved by the use of composite materials disadvantageously again. Alternatively, complex interfaces between the components to be joined must be designed, which adversely increases the development and manufacturing costs of such components.
Der vorliegenden Erfindung liegt somit die Aufgabe zu Grunde, eine Verbindungsanordnung sowie ein Verfahren der eingangs genannten Art bereitzustellen, welche ein besonders einfaches und kostengünstiges Verbinden von Bauteilen aus Faserverbundwerkstoffen bei gleichzeitigem Toleranzausgleich ermöglichen.The present invention is therefore based on the object to provide a connection assembly and a method of the type mentioned above, which allow a particularly simple and cost-effective joining of components made of fiber composites with simultaneous tolerance compensation.
Diese Aufgabe wird durch eine Verbindungsanordnung mit den Merkmalen des Patentanspruchs 1 sowie durch ein Verfahren mit den Merkmalen des Patentanspruchs 5 gelöst.This object is achieved by a connection arrangement having the features of patent claim 1 and by a method having the features of patent claim 5.
Bei einer solchen Verbindungsanordnung zweier Bauteile, von welchem wenigstens eins zumindest überwiegend aus einem Faserverbundwerkstoff ausgebildet ist, weist das erste Bauteil ein Hohlprofilelement auf, dessen Außendurchmesser geringer ist als ein Innendurchmesser eines Hohlprofilelements des zweiten Bauteils. Das Hohlprofilelement des ersten Bauteils ist dabei mit einem Endbereich in das Hohlprofilelement des zweite Bauteils eingesteckt.In such a connection arrangement of two components, of which at least one is formed at least predominantly of a fiber composite material, the first component has a hollow profile element whose outer diameter is smaller than an inner diameter of a hollow profile element of the second component. The hollow profile element of the first component is inserted with an end portion in the hollow profile element of the second component.
Eine derartige Steckverbindung ermöglicht es aufgrund der Durchmesserdifferenz zwischen dem Hohlprofilelementen noch immer, die Bauteile gegeneinander zu verschieben und auszurichten. Hierdurch kann ein besonders einfacher Toleranzausgleich erzielt werden, ohne dass aufwendige Hilfselemente oder komplexe Interfacestrukturen notwendig werden.Such a connector still allows due to the difference in diameter between the hollow profile elements to move the components against each other and align. In this way, a particularly simple tolerance compensation can be achieved without the need for complex auxiliary elements or complex interface structures.
Eine solche Verbindungsanordnung ist daher sowohl in der Entwicklung als auch in der Herstellung besonders kostengünstig.Such a connection arrangement is therefore particularly cost-effective both in development and in production.
In einer bevorzugten Ausführungsform der Erfindung sind die Hohlprofilelemente der beiden Bauteile miteinander verschraubt. Hierdurch kann nach dem Ausrichten der Bauteile gegeneinander, wodurch der gewünschte Toleranzausgleich geschaffen wird, eine Fixierung der beiden Bauteile aneinander erzielt werden, so dass die eingestellte Sollposition zuverlässig gehalten wird.In a preferred embodiment of the invention, the hollow profile elements of the two components are screwed together. In this way, after aligning the components against each other, whereby the desired tolerance compensation is created, a fixation of the two components are achieved together, so that the set target position is reliably maintained.
In weiterer Ausgestaltung der Erfindung weist wenigstens eines der Bauteile eine Klebeflansch auf, mittels welchem es mit den anderen Bauteilen verklebt ist. Hierdurch kann eine alternative oder auch zusätzliche Sicherung und Fixierung der Bauteile gegeneinander erzielt werden.In a further embodiment of the invention, at least one of the components on an adhesive flange, by means of which it is glued to the other components. In this way, an alternative or additional backup and fixation of the components can be achieved against each other.
Vorzugsweise erstrecken sich die Hohlprofilelemente über einen wesentlichen Längenbereich der jeweils zugeordneten Bauteile. Hierdurch erhalten die Hohlprofilelemente eine zusätzliche Funktion. Sie dienen nun nicht mehr nur der Fixierung der Bauteile gegeneinander und den Toleranzausgleich, sondern wirken gleichzeitig als Versteifungs- bzw. Verstärkungselement für die Bauteile und können beispielsweise Trägerfunktionen oder dergleichen übernehmen und beispielsweise im Kraftwagenbau in das Tragwerk der gesamten Karosserie integriert werden.Preferably, the hollow profile elements extend over a substantial length range of the respectively associated components. This gives the hollow profile elements an additional function. They no longer serve only to fix the components against each other and the tolerance compensation, but at the same time act as a stiffening or reinforcing element for the components and can take over, for example, carrier functions or the like and integrated, for example in the motor vehicle in the structure of the entire body.
Die Erfindung betrifft ferner ein Verfahren zum Verbinden zweier Bauteile, von welchen wenigstens eines zumindest überwiegend aus einem Faserverbundwerkstoff ausgebildet ist, wobei ein Hohlprofilelement des ersten Bauteils mit einem Endbereich in ein Hohlprofilelement des zweiten Bauteils eingesteckt wird, eine vorgegebene Relativlage der Bauteile zueinander eingestellt wird und die Bauteile schließlich im Bereich der Hohlprofilelemente gegeneinander fixiert werden.The invention further relates to a method for connecting two components, of which at least one is formed at least predominantly of a fiber composite material, wherein a hollow profile element of the first component is inserted with an end portion in a hollow profile element of the second component, a predetermined relative position of the components is set to each other and the components are finally fixed in the area of the hollow profile elements against each other.
Wie bereits anhand der erfindungsgemäßen Verbindungsanordnung geschildert, kann auf diese Art eine einfache und zuverlässige Verbindung der Bauteile mit gleichzeitigen Toleranzausgleich erzielt werden, ohne das aufwendig gestaltete Hilfselemente oder Schnittstellen vorgesehen werden müssen.As already described with reference to the connection arrangement according to the invention, a simple and reliable connection of the components with simultaneous tolerance compensation can be achieved in this way, without the elaborately designed auxiliary elements or interfaces must be provided.
Vorzugsweise werden die Bauteile durch Verschrauben gegeneinander fixiert, um so auf einfache und reversibel lösbare Art und Weise die eingestellte Sollrelativlage der Bauteile fest zu halten.Preferably, the components are fixed by screwing against each other, so as to hold in a simple and reversibly releasable manner the set desired relative position of the components.
Alternativ oder zusätzlich können die Bauteile im Bereich eines Klebeflansches verklebt werden, um eine weiter verbesserte Sicherung zu erzielen.Alternatively or additionally, the components can be glued in the region of an adhesive flange in order to achieve a further improved fuse.
Es ist besonders zweckmäßig, hierzu einen Expansionsklebstoff zu verwenden, also einen Klebstoff, der sich während des Aushärteprozesses im Volumen ausdehnt. Dies kann den Toleranzausgleich weiter unterstützen, in dem beispielsweise Spalten oder ähnliches durch die Expansion des Klebstoffes geführt werden.It is particularly expedient to use an expansion adhesive for this purpose, ie an adhesive that expands in volume during the curing process. This can further support the tolerance compensation, in which, for example, gaps or the like are guided by the expansion of the adhesive.
