Die Erfindung sieht ferner die Verwendung einer Al-Gusslegierung nach einem der Ansprüche oder eines insbesondere wärmebehandelten Gussbauteils nach einem der Ansprüche für Fahniverksteile von Kraftfahrzeugen, vorzugsweise für radführende Bauteile von Kraftfahrzeugen, ganz besonders bevorzugt für Dämpferstelzen, Radträger oder Schwenklager von Kraftfahrzeugen vor.The invention further provides for the use of an Al casting alloy according to one of the claims or a heat-treated cast component according to one of claims for motor vehicle parts, preferably for wheel-guiding components of motor vehicles, very particularly preferably for damper stilts, wheel carriers or pivot bearings of motor vehicles.

Erfindungsgemäß weisen die Gussbauteile ein verbessertes Festigkeits-Dehnungsverhältnis bei verbesserten Gefügeeigenschaften auf.

On the one hand, the casting process enables one of a large defect, known as voids, free casting, on the other hand, the microstructure is positively influenced in such a way that the number of internal notches, which reduce the elongation at break, is minimized.

Beispielexample

Zur Ermittlung der mechanischen Eigenschaften der Legierung AlSi3Mg0.5Cr0.15 wird ein so genannter "Französischer Zugstab" nach DIN 50125 aus einem mittels eines Gegendruck-Kokillengießverfahrens (CPC-Verfahren) hergestellten Schwenklager herausgetrennt, wobei das Schwenklager vorab eine Wärmebehandlung (Lösungsglühen 540°C für 8h, Abschrecken in Wasser, Warmauslagern 180°C für 6,5h) erhalten hat. Das Gießen von Vergleichsproben (AlSi3Mg0.5 und AlSi3Mg0.5Cr0.3) und die anschließende Wärmebehandlung erfolgt unter gleichen Bedingungen. Die zu vergleichenden Legierungen unterscheiden sich lediglich im Chrom-Gehalt. Der Probenstab wird an gleicher Stelle des Schwenklagers entnommen. Ermittelt werden die mechanischen Eigenschaften Zugfestigkeit Rm, Streckgrenze RP0,2 und Bruchdehnung A5 nach DIN10002. Rm [MPa] Rp 0,2 [MPa] A5 [%] AlSi3Mg0.5 327 263 9,3 AlSi3Mg0.5Cr0.15 356 305 8,2 AlSi3Mg0.5Cr0.3 358 308 6,9 To determine the mechanical properties of the AlSi3Mg0.5Cr0.15 alloy, a so-called "French tensile bar" according to DIN 50125 is separated out of a swivel bearing produced by a counter-pressure die casting process (CPC process), the swivel bearing undergoing a heat treatment in advance (solution annealing 540 ° C for 8 h, quenching in water, hot aging 180 ° C for 6,5 h). The casting of comparative samples (AlSi3Mg0.5 and AlSi3Mg0.5Cr0.3) and the subsequent heat treatment takes place under the same conditions. The alloys to be compared differ only in the chromium content. The sample rod is removed at the same point of the pivot bearing. The mechanical properties tensile strength R m , yield strength R P 0.2 and elongation at break A5 according to DIN10002 are determined. R m [MPa] R p 0.2 [MPa] A5 [%] AlSi3Mg0.5 327 263 9.3 AlSi3Mg0.5Cr0.15 356 305 8.2 AlSi3Mg0.5Cr0.3 358 308 6.9

Vor dem Hintergrund der DE 10 2008 055 928 A1 und dem im Hinblick auf die mechanischen Kennwerte als kritisch angegebenen unteren Grenzwert für Chrom von 0,3 Gew.-% war das Erreichen der oben genannten mechanischen Kennwerte für AlSi3Mg0.5Cr0.15 nicht zu erwarten.Against the background of DE 10 2008 055 928 A1 and with regard to the mechanical values specified as critical lower limit value for chromium of 0.3 wt .-%, the achievement of the above mechanical characteristics for AlSi3Mg0.5Cr0.15 was not expected.

Es kann weiterhin vorteilhaft sein, wenn das Fahrwerksteil, vorzugsweise die Dämpferstelze oder der Radträger, durch Niederdruck-Sandguss oder vorzugsweise durch Gegendruck-Kokillenguss (CPC) hergestellt ist. Als besonders vorteilhaft hat sich die Verwendung der in der DE 10 2010 026 480 A1 offenbarten Gießvorrichtung bzw. des dort offenbarten Verfahrens herausgestellt. Der Offenbarungsgehalt der DE 10 2010 026 480 A1 bzw. deren Inhalt wird durch ausdrücklichen Verweis als zum Gegenstand der vorliegenden Anmeldung gehörig in die vorliegende Anmeldung aufgenommen bzw. integriert.It can also be advantageous if the chassis part, preferably the damper stilts or the wheel carrier, by low-pressure sand casting or preferably by counter-pressure chill casting (CPC) is made.
