Description
Fahrzeugstrukturelement aus Leichtmetall Vehicle structure element made of light metal
Die Erfindung betrifft ein Fahrzeugstrukturelement ausThe invention relates to a vehicle structural element
Leichtmetall gemäß dem Oberbegriff des Patentanspruchs 1. Ein solches Strukturelement ist bereits aus der DE 195 18 946 AI bekannt .Light metal according to the preamble of claim 1. Such a structural element is already known from DE 195 18 946 AI.
Gemäß der DE 195 18 946 wird ein. Fahrzeugstrukturelement aus Leichtmetall gefertigt, um Gewicht einzusparen. Problematisch ist dabei, dass Festigkeit und Dehnung von derartigen Strukturelementen aus Leichtmetallen deutlich schlechtere Werte aufweisen als die vergleichbaren üblichen Strukturelemente aus Stahl. Um dies auszugleichen wird in der DE 195 18 946 AI vorgeschlagen, in ein aus Plattenelementen aus Leichtmetall gefertigtes Strukturelement ein aus Leichtmetallextrudat hergestelltes Verstärkungselement derart einzupassen, dass es dem inneren Querschnitt des Strukturelementes folgt. Eine derartige Ausgestaltung erfordert eine vergleichsweise aufwendige Querschnittsform des Verstärkungselementes.According to DE 195 18 946 a. Vehicle structure element made of light metal to save weight. The problem here is that the strength and elongation of such structural elements made of light metals have significantly poorer values than the comparable conventional structural elements made of steel. In order to compensate for this, it is proposed in DE 195 18 946 A1 to fit a reinforcing element made of light metal extrudate into a structural element made of plate elements made of light metal in such a way that it follows the inner cross section of the structural element. Such a configuration requires a comparatively complex cross-sectional shape of the reinforcing element.
Die Aufgabe der vorliegenden Erfindung besteht darin, ein Fahrzeugstrukturelement aus Leichtmetall anzugeben, welches bezüglich Festigkeit und Dehnung mindestens vergleichbareThe object of the present invention is to provide a vehicle structural element made of light metal which is at least comparable in terms of strength and elongation
Werte zu bisherigen stahlverstärkten Strukturelementen aufweist und einfacher und kostengünstiger zu fertigen ist als bisherige leichtmetallische Fahrzeugstrukturelemente. Diese Aufgabe wird von einem Fahrzeugstrukturelement mit den Merkmalen des Oberbegriffs von Patentanspruch 1 durch dessen kennzeichnende Merkmale gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen angegeben.Has values for previous steel-reinforced structural elements and is easier and cheaper to manufacture than previous light-metallic vehicle structural elements. This object is achieved by a vehicle structural element with the features of the preamble of claim 1 by the characterizing features. Advantageous refinements are specified in the subclaims.
Ein erfindungsgemäßes Fahrzeugstrukturelement aus Leichtmetall, z.B. eine A-Säule, enthält mindestens ein Schalenelement und mindestens ein Verstärkungselement, wobei das Schalenelement ein Gussbauteil ist und das Verstärkungsele- ment ein Strangpressprofil, wobei das Profil über seine gesamte Länge einen im wesentlichen gleichen Querschnitt aufweist und mit dem Schalenelement über Querrippen verbunden ist .A vehicle structural element according to the invention made of light metal, e.g. An A-pillar contains at least one shell element and at least one reinforcing element, the shell element being a cast component and the reinforcing element being an extruded profile, the profile having an essentially identical cross section over its entire length and being connected to the shell element via transverse ribs.
Die Herstellung des Schalenelementes durch Guss, vorzugsweise Druckguss, senkt die Kosten. Dies gilt insbesondere für kleine Schalenelemente, weshalb das Strukturelement auch vorteilhaft aus mehreren kleinen Schalenelementen zusammengefügt werden kann. Darüber hinaus gewährt die Gießtechnik eine hohe Designfreiheit, weshalb weniger Einzelteile hergestellt und später gefügt werden müssen. Variable Wandstärken sind leicht umsetzbar, insbesondere können die Querrippen mitgegossen werden. Als weiterer Vorteil sind die geringen Eigenspannungen von Gussbauteilen und ihr gutes Dämpfungsverhalten (Vib- rationen, Akustik) zu nennen.The production of the shell element by casting, preferably die casting, lowers the costs. This applies in particular to small shell elements, which is why the structural element can also advantageously be assembled from several small shell elements. In addition, the casting technology allows a high degree of design freedom, which is why fewer individual parts have to be manufactured and later joined. Variable wall thicknesses are easy to implement, in particular the cross ribs can also be cast. Another advantage is the low internal stresses of cast components and their good damping behavior (vibrations, acoustics).
Das Strangpressen eines Profils mit einem über seine gesamte Länge im wesentlichen gleichen Querschnitt ist ebenfalls kostengünstiger als das Extrudieren eines Profils mit einem dem Innenquerschnitt des Strukturelementes folgenden Querschnitt.Extruding a profile with a cross section that is essentially the same over its entire length is also less expensive than extruding a profile with a cross section that follows the internal cross section of the structural element.
Der Einsatz von Querrippen in dem Schalenelement gewährleistet eine ausreichende Kraftübertragung zwischen Schalenelement und Verstärkungselement. Gleichzeitig erlaubt er die In- nengeometrie des Schalenelementes und die Außengeometrie des Verstarkungselementes einfach und damit kostengünstig zu gestalten. Darüber hinaus verringern die zwischen Schalenelement, Verstarkungselement und Querrippen vorhandenen Hohlrau- me das Gesamtgewicht des Strukturelementes.The use of transverse ribs in the shell element ensures sufficient power transmission between the shell element and the reinforcing element. At the same time, it allows in- NEN geometry of the shell element and the outer geometry of the reinforcing element to make simple and therefore inexpensive. In addition, the hollow spaces present between the shell element, reinforcing element and transverse ribs reduce the overall weight of the structural element.
Besonders vorteilhaft erweist sich die Verwendung von Rechteckprofilen aufgrund ihrer besonders einfach mittels Strangpressen herstellbaren Geometrie. Darüber hinaus weisen Recht- eckprofile besonders hohe Widerstandsmomente auf, wodurch das Defizit an Festigkeit von Leichtmetall gegenüber den üblichen Stahlrohren kompensiert werden kann.The use of rectangular profiles has proven to be particularly advantageous on account of their geometry, which can be produced particularly easily by means of extrusion molding. In addition, rectangular profiles have particularly high resistance moments, which means that the deficiency in the strength of light metal compared to conventional steel pipes can be compensated for.
Besonders geeignete Leichtmetalle sind hochfeste Aluminium- Legierungen:Particularly suitable light metals are high-strength aluminum alloys:
Für das Schalenelement ist beispielsweise eine AlMg5Si2Mn- Legierung (Handelsname: Magsimal 59) vorteilhaft, die Druck- guss geeignet ist und darüber hinaus auch gut schweißbar, was spatere Reparaturen erleichtert. Deren geringer Eisengehalt verbessert die Duktilitat. Gleichzeitig wurde der Mangangehalt zur Vermeidung des Klebens in der Druckgussform angehoben, damit einher geht eine erwünschte Verbesserung der Warmfestigkeit. Der hohe Magnesiumgehalt dient der Einstellung einer hohen Festigkeit. Auch geeignet sind AlSigMgMn- bis Al- SinMgMn-Legierungen (Handelsname: Silafont) , die sowohl Druckguss als auch sehr gut Sandguss geeignet sind. Außerdem sind diese Legierungen gut zerspanbar und korrosionsbeständig.For the shell element, for example, an AlMg 5 Si 2 Mn alloy (trade name: Magsimal 59) is advantageous, which is suitable for die casting and is also easy to weld, which makes subsequent repairs easier. Their low iron content improves ductility. At the same time, the manganese content was increased to avoid sticking in the die-casting mold, which is accompanied by a desired improvement in the heat resistance. The high magnesium content serves to establish a high strength. Also suitable are AlSigMgMn to Al-SinMgMn alloys (trade name: Silafont), which are suitable for both die casting and sand casting. In addition, these alloys are easy to machine and corrosion-resistant.
Für das Verstarkungselement sind Zink- und Kupfer-basierte Legierungen mit den Bezeichnungen (gemäß der europaischen Norm EN 573-3:2003) AW7xxx und AW2xxx, insbesondere AW7108 oder auch eine AlZn5,5Mgι,5Mn-Legierung, aufgrund ihrer hohen Festigkeit vorteilhaft. Geeignet sind aber auch die Si-basie- rende Aluminiumlegierungen AWδxxx, z.B. AW6056 und AW6082. Diese Aluminium-Legierungen weisen außerdem eine hohe Dukti- lität auf.For the reinforcing element are zinc and copper-based alloys with the designations (according to the European standard EN 573-3: 2003) AW7xxx and AW2xxx, in particular AW7108 or an AlZn 5 , 5 Mgι, 5 Mn alloy, due to their high Strength advantageous. However, the Si-based aluminum alloys AWδxxx, for example AW6056 and AW6082, are also suitable. These aluminum alloys also have a high ductility.
Darüber hinaus weisen die verschiedenen Aluminium-Legierungen ähnliche Ausdehnungskoeffizienten auf. Dies hat gegenüber stahlverstärkten Leichtmetall-Strukturelementen den Vorteil, dass geringere Spannungen und Verzüge auftreten, insbesondere bei Nachfolgeprozessen wie z.B. KTL (Kathodische Tauch-In addition, the different aluminum alloys have similar expansion coefficients. This has the advantage over steel-reinforced light metal structural elements that lower stresses and distortions occur, especially in subsequent processes such as KTL (cathodic diving
