Description
Die Erfindung betrifft ein aus einer Leichmetall-Legierung gegossenes Bauteil mit einem verlorenen Leichtmetallkern.The The invention relates to a casting of a light alloy Component with a lost light metal core.

Aufgabe der Erfindung ist es, ein gattungsgemäßes Bauteil, insbesondere einen Radträger für die Radaufhängung eines Kraftfahrzeuges derart weiterzubilden, daß unter Beibehaltung einer gewichtsgünstigen Konstruktion höhere Festigkeiten erzielbar sind.task The invention is a generic component, in particular a wheel carrier for the suspension of a Develop motor vehicle such that while maintaining a low-weight Construction higher Strengths are achievable.
Diese Aufgabe wird erfindungsgemäß mit den kennzeichnenden Merkmalen des Patentanspruches 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind den weiteren Patentansprüchen entnehmbar.These Task is according to the invention with the characterizing features of claim 1. advantageous Further developments of the invention can be taken from the further claims.
Erfindungsgemäß wird vorgeschlagen, den Hohlkörper aus einem höherfesteren Material, und zwar als Strangpreßteil, herzustellen. Derartige Teile sind höherverdichtet und im wesentlichen lunkerfrei, wodurch bei einer entsprechenden Anordnung des Hohlkörpers im hochbelasteten Bereich des Bauteiles eine zuverlässige, robuste Konstruktion herstellbar ist.According to the invention, it is proposed the hollow body from a higher strength Material, as an extrusion, to produce. such Parts are higher compressed and substantially void-free, whereby at a corresponding Arrangement of the hollow body in the highly loaded area of the component a reliable, robust Construction can be produced.
Darüber hinaus ist der Hohlkörper im Innenhochdruckumformverfahren definiert umgeformt, so daß dessen Außenkontur dem Bauteil entsprechend angepaßt ist. Durch eine geschlossene Ausbildung wird einerseits beim Gießverfahren ein Innendruck in dem Hohlkörper hergestellt, der den äußeren Verformungskräften beim Gießen entgegenwirkt und andererseits eine extrem leichte Konstruktion ermöglicht.Furthermore is the hollow body deformed defined in the hydroforming process, so that its outer contour adapted to the component accordingly is. By a closed training is on the one hand during the casting process an internal pressure in the hollow body produced, the outer deformation forces during to water counteracts and on the other hand, an extremely lightweight construction allows.
Aufgrund der sich herstellenden stoffschlüssigen Verbindung beim Gießen, die ggf. durch Vorwärmen des Hohlkörpers noch gefördert werden kann, wird eine innige Verbindung zwischen Kern und Bauteil zur sicheren Einbindung und Spannungsübertragung gewährleistet.by virtue of the producing cohesive Connection during casting, possibly by preheating of the hollow body still encouraged becomes an intimate connection between core and component ensures safe integration and voltage transmission.
Der Hohlkörper bzw. Kern kann mit Fixierungszapfen versehen sein, mittels denen eine genaue Positionierung des Kernes beim Gießen des Bauteiles erreicht wird.Of the hollow body or core may be provided with fixing pins, by means of which achieved an exact positioning of the core during casting of the component becomes.
Bevorzugt wird vorgeschlagen, das Bauteil zur Herstellung eines Radträgers einer Radaufhängung für Kraftfahrzeuge oder für andere Radführungsteile oder beispielsweise für hochbelastete Hilfsrahmen für Aggregateaufhängungen oder Radführungen zu verwenden.Prefers is proposed, the component for producing a wheel carrier a Arm for motor vehicles or for other wheel guide parts or for example heavily loaded subframe for Aggregate suspensions or bike rides to use.
