Abstract

The wheel support of a vehicle is made of die-cast Al with a hollow cavity (9) filled with Al foam (10).

Description

Bauteile aus Aluminiumdruckguß für das Fahrwerk eines Kraftfahrzeuges sind aus DE-Z "Automobiltechnische Zeitschrift", 95 1993, Nr. 11, Seiten 552 bis 563 bekannt.Die-cast aluminum components for the chassis of a Motor vehicle are from DE-Z "automotive engineering Journal ", 95 1993, No. 11, pages 552 to 563 known.

Die DE 41 16 837 C2 offenbart ein Bauteil für das Fahrwerk eines Kraftfahrzeuges, welches ein Hohlraumprofil mit einer aufgeschäumten Kernfüllung zur Verstärkung aufweist.DE 41 16 837 C2 discloses a component for the Chassis of a motor vehicle, which has a cavity profile with a foamed core filling for reinforcement having.

Bei Gravitations- und Niederdruckgußverfahren ist es seit langem Stand der Technik, zur Herstellung von Bauteilen mit einem Hohlraumprofil Kerne aus Sand, Wachs, Styropor oder einem anderen geeigneten Werkstoff in die Gießform einzulegen und nach dem Gießen durch eine oder mehrere Öffnungen in der Wandung des Bauteiles zu entfernen. Es ist auch bekannt, solche Kerne in Einzelfällen in dem Hohlraum des Bauteiles zu belassen. Eine solche Herstellung ist bei der Anwendung eines Druckgußverfahrens nicht möglich, weil der Innendruck der Gießform mehr als 30 bar beträgt, so daß der Kern diesem Druck ebensowenig standhält wie den Turbulenzen beim schnellen Füllen der Gießform mit flüssigem Metall, zum Beispiel Aluminium oder Magnesium.It has been in gravitational and low pressure casting processes long state of the art, for the production of components with a cavity profile cores made of sand, wax, polystyrene or another suitable material in the mold insert and after pouring through one or more Remove openings in the wall of the component. It is also known, such cores in individual cases in the cavity of the component. Such manufacture is at the application of a die casting process is not possible because the internal pressure of the mold is more than 30 bar, so that the core cannot withstand this pressure any more than it can Turbulence when filling the mold quickly liquid metal, for example aluminum or magnesium.

Bekannt ist aus JP 1-127 451 A und aus DE-Z. "Aluminium", 70 1994, 3/4, Seiten 212, 213, Aluminiumschaum als leichten Werkstoff für Bauteile generell zu verwenden. It is known from JP 1-127 451 A and from DE-Z. "Aluminum", 70 1994, 3/4, pages 212, 213, aluminum foam as light Use material for components in general.  

Besonders bei der Herstellung eines Bauteiles für das Fahrwerk moderner Kraftfahrzeuge, insbesondere eines häufig hochbelasteten Bauteiles, gewinnt die Gewichtsreduzierung hochfester Bauteile zunehmend an Bedeutung. Bekannt ist die Herstellung solcher Bauteile aus Aluminium. Fahrwerkskomponenten mit hoher Steifigkeit bei minimalem Gewicht werden als Hohlteile aus Blech mit relativ dünner Schalenwandung und optimiertem Profil ausgebildet. Geschlossene Profile sind wesentlich steifer und leichter als offene Profile mit außenliegenden Rippen, Wulsten oder dergleichen, zur Versteifung. Vor allem Bauteile des Fahrwerks, die mit hoher Steifigkeit große Torsions- und Biegemomente übertragen, wie Fahrwerkslenker oder Achsschenkel, werden vorzugsweise als in sich geschlossene Hohlkörper aus dünnen Blechschalen hergestellt oder aus Aluminiumwerkstoffen mit entsprechender Materialdicke gegossen.Especially when manufacturing a component for the Chassis of modern motor vehicles, especially one often highly stressed component, the weight reduction wins high-strength components are becoming increasingly important. The is known Manufacture of such components from aluminum. Chassis components with high rigidity with minimal Weight are hollow parts made of sheet metal with relatively thinner Shell wall and optimized profile. Closed profiles are much stiffer and lighter as open profiles with external ribs, beads or the like, for stiffening. Especially components of the Chassis that with high rigidity great torsion and Bending moments transmitted, such as suspension arm or Knuckles are preferably considered self-contained Hollow body made from thin sheet metal shells or from Aluminum materials with the appropriate material thickness poured.

Es ist Aufgabe der Erfindung, eine Lösung zu finden, um einteilige Bauteile mit einem Hohlraumprofil zur Gewichtsreduzierung und Erhöhung ihrer Steifigkeit auf möglichst rationelle Weise in großen Stückzahlen herstellen zu können.It is an object of the invention to find a solution to one-piece components with a cavity profile Losing weight and increasing their stiffness produce in large quantities as rationally as possible to be able to.

Die Lösung dieser Aufgabe besteht erfindungsgemäß darin, daß ein Bauteil mit Merkmalen nach dem Patentanspruch 1 zur Anwendung gelangt.According to the invention, this object is achieved by that a component with features according to claim 1 Application arrives.

Das erfindungsgemäße Verfahren zur Herstellung eines solchen Bauteils besteht darin, daß in eine Druckgußform Kerne aus Aluminiumschaum eingebracht werden, die nach dem Einpressen des Aluminiums in das Formwerkzeug in dem Bauteil aus Aluminiumdruckguß verbleiben. The inventive method for producing a such component is that in a die Cores made of aluminum foam are introduced, which after the Pressing the aluminum into the mold in the Die cast aluminum component remain.  

Erfindungsgemäß werden somit zur Erzielung hochsteifer und gewichtsminimierter Bauteile Kerne aus vorgeformtem Aluminiumschaummaterial verwendet. Der Aluminiumschaum besteht aus einer Mischung von Aluminiumpulver mit einem Treibmittel, zum Beispiel Titanhydrid (TiH₂). Diese Pulvermischung wird in eine Form entsprechend der Kernkontur eingebracht und auf etwa 800° Celsius erhitzt. Bei dieser hohen Temperatur setzt das Treibmittel eingeschlossenes Gas aus, so daß es ähnlich wie beim Polyurethanschaum wirksam ist und das Aluminiumpulver aufschäumt. Gleichzeitig werden Aluminiumkörner zusammengebacken, so daß eine schaumige Masse die Kontur der Kernform ausfüllt, welche eine Dichte von etwa 0,6 bis 0,7 Gramm pro Zentimeter³ mit geschlossener Porosität entsteht, die sehr fest ist, so daß die Kernmasse hohen Drucken über 30 bar ohne Zerstörung standhält. Ein in dem Bauteil verbleibender Kern aus aufgeschäumtem Aluminium ist sehr druckfest, hat ein geringes Gewicht, eignet sich im Crashfalle zur Energieabsorption und weist eine geschlossene Porosität auf. Vor allem wird durch den in dem Bauteil verbleibenden Kern aus aufgeschäumtem Aluminium eine wesentliche Erhöhung der Biegefestigkeit des Hohlprofiles erreicht.According to the invention are thus highly rigid and Weight-minimized components Cores made from preformed Aluminum foam material used. The aluminum foam consists of a mixture of aluminum powder with a Blowing agents, for example titanium hydride (TiH₂). These Powder mixture is made in a form corresponding to the Core contour introduced and heated to about 800 ° Celsius. The blowing agent sets at this high temperature trapped gas, so that it is similar to the Polyurethane foam is effective and the aluminum powder foams. At the same time, aluminum grains baked together so that a foamy mass forms the contour fills the core shape, which has a density of about 0.6 to 0.7 grams per centimeter³ with closed porosity arises, which is very firm, so that the core mass is high Withstands pressures above 30 bar without destruction. One in the The remaining core is made of foamed aluminum very pressure resistant, light weight, suitable for Crash trap for energy absorption and has one closed porosity. Above all, through the in the Component remaining core made of foamed aluminum a significant increase in the bending strength of the Hollow profile reached.

Der Kern aus aufgeschäumtem Aluminium wird an den wenig belasteten Stellen an der Innenwand des Gußwerkzeuges abgestützt bzw. befestigt, damit zwischen dem Kern und dem Werkzeug ein gleichmäßiger Abstand in gewünschter Wanddicke verbleibt.The core made of foamed aluminum is attached to the little stressed areas on the inner wall of the casting tool supported or attached so that between the core and the Tool an even distance in the desired wall thickness remains.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigen: In the drawing is an embodiment of the invention shown. Show it:  

Fig. 1 einen Achsschenkel in perspektivischer Darstellung und Fig. 1 shows a knuckle in perspective and

Fig. 2 einen Querschnitt des Achsschenkels nach Fig. 1. Fig. 2 shows a cross-section of the stub axle of FIG. 1.

Der in Fig. 1 dargestellte Achsschenkel 1 entspricht einer in der Praxis häufig vorkommenden Ausführungsform mit einem relativ langen vertikalen Hebelarm 2. Das am oberen Ende ausgebildete Lagerauge 3 dient zur Befestigung der Spurstange. An die Lageraugen 4 werden obere Lenker angelenkt. Die unteren Lenker werden an die unteren Lageraugen 5 angeschlossen. Mit der Bezugsziffer 6 ist die Bremsscheibe und mit der Bezugsziffer 7 ein Bremssattel bezeichnet. Zwischen der Achsbohrung 8 und den oberen Lageraugen 4 weist der Hebel 2 des Achsschenkels 1 ein an die hauptsächlichen Belastungen und deren Wirkungsrichtung angepaßtes Hohlprofil 9 auf, in deren Hohlraum 9 sich ein Kern 10 aus Aluminiumschaum befindet, der bei der Herstellung des Achsschenkels 1 aus Aluminiumdruckguß in das Formwerkzeug eingebracht ist und nach der Druckgußherstellung des Achsschenkels 1 in dem Hohlraum verbleibt, wie es zuvor erläutert worden ist. Erreicht wird auf diese Weise, daß der Achsschenkel wegen des Profils seiner dünnen Außenwand trotz seines langen Hebelarmes 2 besonders torsionsfest, trotzdem aber sehr leicht ist. Dadurch wird eine präzise Lenkung des Fahrzeuges ermöglicht und eine Grundforderung an ungefederte Massen im Fahrwerksbau erfüllt.The steering knuckle 1 shown in Fig. 1 corresponds to a frequently occurring in practice embodiment with a relatively long vertical arm. 2 The bearing eye 3 formed at the upper end serves to fasten the tie rod. Upper links are articulated to the bearing eyes 4 . The lower links are connected to the lower bearing eyes 5 . The reference number 6 denotes the brake disc and the reference number 7 a brake caliper. Between the axle bore 8 and the upper bearing eyes 4 , the lever 2 of the steering knuckle 1 has a hollow profile 9 adapted to the main loads and their direction of action, in the hollow space 9 of which there is a core 10 made of aluminum foam, which is used for the production of the steering knuckle 1 from die-cast aluminum is introduced into the mold and remains after the pressure casting of the steering knuckle 1 in the cavity, as previously explained. It is achieved in this way that the steering knuckle is particularly torsion-proof due to the profile of its thin outer wall, despite its long lever arm 2 , but is nevertheless very light. This enables precise steering of the vehicle and fulfills a basic requirement for unsprung masses in chassis construction.
