Die Erfindung betrifft eine Stahlblechkonstruktion nach dem Oberbegriff des Patentanspruchs 1 der Erfindung. Gemäß Anspruch 6 der Erfindung betrifft dieselbe des Weiteren ein Fahrzeug, insbesondere Kraftfahrzeug, mit einer derartigen Stahlblechkonstruktion. Gemäß Anspruch 7 der Erfindung betrifft dieselbe ferner ein Verfahren zur Herstellung der besagten The invention relates to a steel construction according to the preamble of claim 1 of the invention. According to claim 6 of the invention further relates to a vehicle, in particular motor vehicle, with such a steel sheet construction. According to claim 7 of the invention further relates to a method for producing the said
Stahlblechkonstruktion. Sheet steel construction.
Aus der DE 10 2004 032 471 A1 ist ein verzinktes Fahrwerksbauteil in Blechkonstruktion aus mindestens zwei Blechelementen bekannt. Dabei sind zwei Blechelemente an mindestens einer Verbindungsstelle schweißnahtfrei miteinander zusammengefügt, sozusagen durch das Verzinken des Fahrwerksbauteils miteinander verlötet. Im Besonderen wird hier ein unter bestimmten Umständen beim Verzinken auftretender Löteffekt gezielt zur Verbindung einzelner oder aller Blechelemente eines entsprechend zusammengesetzten Fahrwerkbauteils genutzt. Die Verbindung der Blechelemente geschieht gleichzeitig mit der Anbringung eines From DE 10 2004 032 471 A1 a galvanized chassis component in sheet metal construction of at least two sheet metal elements is known. In this case, two sheet metal elements are welded together weld-free at least one joint, as it were soldered together by galvanizing the chassis component. In particular, a soldering effect occurring under certain circumstances during galvanizing is purposefully used for connecting individual or all sheet metal elements of a correspondingly assembled chassis component. The connection of the sheet metal elements is done simultaneously with the attachment of a
Korrosionsschutzes durch besagtes Verzinken. Aus der DE 10 2006 006 910 B3 sind eine Karosserierahmenstruktur oder Fahrwerksstruktur eines Kraftfahrzeugs mit Corrosion protection by said galvanizing. From DE 10 2006 006 910 B3 are a body frame structure or chassis structure of a motor vehicle with
Stahlstrukturbauteilen bekannt, wobei zumindest die tragenden Stahlstrukturbauteile als Korrosionsschutzbeschichtung eine Zinklamellenbeschichtung tragen. Überdies wird mit dieser Druckschrift vorgeschlagen, zunächst das Fügen der Strukturbauteile durch insbesondere Schweißung und danach die Zinklamellenbeschichtung durchzuführen. Die DE 10 2008 027 169 A1 beschreibt ein Fahrwerksbauteil eines Kraftfahrzeugs, mit wenigstens einem Hohlkörper aus einem korrosionsgefährdeten Material, der einen Hohlraum enthält, welcher Hohlraum flüssigkeitsdicht und feuchtigkeitsdicht verschlossen ist. Hierbei wird von der Erkenntnis ausgegangen, dass bei Verwendung von bereits verzinkten Blechen zur Herstellung des Hohlkörpers, wodurch bereits verzinkte Innenflächen vorliegen, beim Verschweißen dieser Bleche die Zinkbeschichtung verdampft und so eine Schwachstelle im Korrosionsschutz entsteht. Um diesem nachteiligen Umstand zu begegnen, wird im Wesentlichen vorgeschlagen, zunächst das Fahrwerksbauteil mit dem flüssigkeitsdicht und feuchtigkeitsdicht verschlossenen Hohlkörper zu fertigen und anschließend außen am Fahrwerksbauteil eine Korrosionsschutzbeschichtung, insbesondere eine Verzinkung aufzubringen, ggf. kombiniert mit einer Lackierung. Steel structural components known, wherein at least the supporting steel structural components wear a zinc flake coating as corrosion protection coating. Moreover, this document proposes first to perform the joining of the structural components by, in particular, welding and then the zinc flake coating. DE 10 2008 027 169 A1 describes a chassis component of a motor vehicle, with at least one hollow body made of a material susceptible to corrosion, which contains a cavity, which cavity is sealed in a liquid-tight and moisture-proof manner. This is based on the knowledge that when using already galvanized sheets for the production of the hollow body, which already present galvanized inner surfaces, the zinc coating evaporates during welding of these sheets and thus creates a weak spot in the corrosion protection. In order to counteract this disadvantageous circumstance, it is essentially proposed to first manufacture the chassis component with the hollow body sealed in a moisture-tight and moisture-tight manner, and then, on the outside of the chassis component Anti-corrosion coating, in particular a galvanizing apply, possibly combined with a paint job.
Aufgabe der Erfindung ist es, eine korrosionsgeschützte Stahlblechkonstruktion zu schaffen, welche im Hinblick auf den Stand der Technik zur Herstellung der besagten The object of the invention is to provide a corrosion-resistant sheet steel construction, which, in view of the prior art for the production of said
Stahlblechkonstruktion eines minimierten Aufwandes bedarf. Aufgabe der Erfindung ist es ferner, ein Fahrzeug, insbesondere Kraftfahrzeug, mit einer derartigen Stahlblechkonstruktion bereitzustellen. Schließlich ist es Aufgabe der Erfindung, ein geeignetes Verfahren zur Sheet steel construction requires a minimum of effort. The object of the invention is also to provide a vehicle, in particular a motor vehicle, with such a sheet steel construction. Finally, it is an object of the invention to provide a suitable method for

Ausgehend von einer Stahlblechkonstruktion, bestehend aus zumindest zwei untereinander durch Schweißung gefügten Stahlblechteilen, wird die gestellte Aufgabe dadurch gelöst, dass wenigstens eines der Stahlblechteile aus einem einseitig verzinkten Vormaterial gefertigt ist, wogegen das/die andere/n Stahlblechteil/e aus einem nichtverzinkten, ebenfalls einseitig verzinkten oder wenigstens im Bereich von Schweißstellen lokal nicht verzinkten Vormaterial gefertigt ist/sind, und dass die Stahlblechteile im Bereich zueinander korrespondierender nichtverzinkter Seiten untereinander durch Schweißung gefügt sind. Starting from a steel construction, consisting of at least two steel sheet parts joined together by welding, the stated object is achieved in that at least one of the sheet steel parts is made of a one-sided galvanized starting material, whereas the / the other / s sheet metal part / s of a non-galvanized, also one-sided galvanized or at least in the region of welds locally non-galvanized starting material is / is made, and that the steel sheet parts are joined together in the region of non-galvanized sides corresponding to each other by welding.
Aufgrund der Tatsache, dass einseitig verzinktes Vormaterial Verwendung findet und demgemäß einseitig verzinkte Stahlblechteile zum Verschweißen bereitgestellt werden, ist der Aufwand zur Herstellung von Stahlblechkonstruktionen vorteilhaft minimiert. Überdies ist durch diese Maßnahme gewährleistet, dass keine den Schmelzschweißprozess beeinträchtigende Zink-Gase entstehen. Due to the fact that unilaterally galvanized starting material is used and accordingly unilaterally galvanized sheet steel parts are provided for welding, the cost of producing sheet steel structures is advantageously minimized. Moreover, this measure ensures that no zinc gases impairing the fusion welding process are formed.
Die Unteransprüche beschreiben bevorzugte Weiterbildungen oder Ausgestaltungen der Erfindung. The subclaims describe preferred developments or refinements of the invention.

Für die andere Seite des Fahrwerksteils respektive Federlenkers, welche nicht oder nur wenig Steinschlag ausgesetzt ist, ist bevorzugt ein im Hinblick auf eine Zinkbeschichtung kostengünstigerer Korrosionsschutz, wie beispielsweise eine KTL-Beschichtung (KTL = kathodische Tauchlackierung), vorgesehen. Weiter vorteilhaft ist die Stahlblechkonstruktion auch als ein hohlraumbildendes Teil, insbesondere eines Kraftfahrzeugs, einsetzbar, wobei die Zinkbeschichtung bevorzugt im Inneren des besagten Hohlraums angeordnet ist. Eine Schädigung der hohlraumbildenden Stahlblechkonstruktion durch Korrosion infolge innerhalb des Hohlraums stehenden Wassers ist durch diese Maßnahme wirkungsvoll vermieden. Die Außenseite der hohlraumbildenden Stahlblechkonstruktion weist mangels übermäßiger mechanischer Belastung bevorzugt ebenfalls eine KTL-Beschichtung auf. Rockfall is exposed. This measure advantageously combines protection against corrosion with protection against falling rocks. For the other side of the chassis part or spring link, which is not or little exposed to stone chipping, is a preferred in terms of a zinc coating corrosion protection, such as For example, a KTL coating (KTL = cathodic dip coating), provided. Further advantageously, the sheet steel construction can also be used as a cavity-forming part, in particular of a motor vehicle, wherein the zinc coating is preferably arranged in the interior of the said cavity. Damage to the cavity-forming sheet steel construction due to corrosion due to standing within the cavity water is effectively avoided by this measure. The outside of the cavity-forming steel sheet construction preferably also has a cathodic dip-coating due to the lack of excessive mechanical stress.

At the spring arm, the body of the vehicle is supported by a steel spring on a vehicle axle (not shown in the drawing). The said spring link forming sheet steel construction 1 comprises a first deep-drawn sheet steel part 1 a, which
Stahlblechteil 1 a einenends an der Karosserie des Fahrzeugs und anderenends an der Fahrzeugachse befestig bar ist. Dem ersten Stahlblechteil 1 a ist ein zweites tiefgezogenes Stahlblechteil 1 b in Form einer Federaufnahme zugeordnet, welche Federaufnahme durch Schweißung, insbesondere nach einem Schmelzschweißverfahren mit dem ersten Sheet steel part 1 a at one end to the body of the vehicle and the other end of the vehicle axle is fastened bar. The first sheet steel part 1 a is a second deep-drawn sheet steel part 1 b assigned in the form of a spring receiving, which spring receiving by welding, in particular by a fusion welding process with the first
Stahlblechteil 1 a fest verbindbar ist. Unter Schmelzschweißen wird im Allgemeinen das Fügen von meist gleichartigen Metallen verstanden, indem das Metall an den Schweißstellen 2 (Fig. 2) geschmolzen und mit oder ohne die Zugabe von Zusatzwerkstoff vereinigt wird.

Um vorsorglich diesem nachteiligen Umstand zu begegnen, werden die Stahlblechteile 1 a, 1 b herkömmlich nach dem Fügen mit einer Korrosionsschutzschicht, insbesondere einem KTL-Lack versehen. Kathodische Tauchlackierung (KTL) ist ein Rockfall exposed. As a precaution to counter this disadvantageous circumstance, the steel sheet parts 1 a, 1 b are conventionally provided after joining with a corrosion protection layer, in particular a cathodic dip paint. Cathodic dip painting (KTL) is a
elektrochemisches Verfahren, bei dem der Federlenker in einem Tauchbad beschichtet wird. Allein besagter KTL-Lack kann erhöhten mechanischen Beanspruchungen durch insbesondere besagten Steinschlag nicht ausreichend Widerstand entgegenbringen. Um diesem Problem zu begegnen, ist es bekannt, dem Federlenker eine zusätzliche Kunststoffabdeckung zuzuordnen, woraus jedoch erhöhter Aufwand und erhöhte Kosten resultieren. electrochemical process in which the spring link is coated in a dip. Alone said KTL paint can not provide sufficient resistance to increased mechanical stresses caused by particular rockfall. To address this problem, it is known to associate the spring link an additional plastic cover, but this results in increased effort and increased costs.
Demgegenüber ist nunmehr erfindungsgemäß vorgesehen, dass das erste Stahlblechteil 1 a der beispielgebend einen Federlenker ausbildenden Stahlblechkonstruktion 1 aus einem einseitig verzinkten Vormaterial gefertigt ist, wogegen das zweite Stahlblechteil 1 b gemäß diesem Ausführungsbeispiel aus einem nichtverzinkten Vormaterial gefertigt ist. Die Zinkbeschichtung 3 des ersten Stahlblechteils 1 a ist auf der durch Steinschlag mechanisch belasteten, respektive zum Fahrweg weisenden Seite der Stahlblechkonstruktion 1 angeordnet. Untereinander verschweißt sind die Stahlblechteile 1 a, 1 b im Bereich zueinander korrespondierender nichtverzinkter Seiten (Fig. 2). In contrast, it is now provided according to the invention that the first sheet steel part 1 a of example a spring arm forming sheet steel construction 1 is made of a one-sided galvanized starting material, whereas the second sheet steel part 1 b is made according to this embodiment of a non-galvanized starting material. The zinc coating 3 of the first sheet steel part 1 a is arranged on the side of the sheet steel construction 1 mechanically loaded by stone chipping, respectively facing the guideway. Welded together, the steel sheet parts 1 a, 1 b in the region corresponding to each other nichtverzinkter sides (Fig. 2).
Derartige einseitig verzinkte Bleche (Vormaterial) können vorteilhaft mittels einer sogenannten Bandverzinkungsanlage nach einem elektrolytischen Verzinkungsverfahren hergestellt werden, bei dem in Reihe geschaltete galvanische Zellen Verwendung finden. Durch ein elektrisches Feld zwischen dem Stahlband und Anodengruppen wird in der Elektrolytflüssigkeit gelöstes Zink auf der Bandoberfläche abgeschieden. Wahlweise selektives Abschalten der Such unilaterally galvanized sheets (semi-finished material) can advantageously be produced by means of a so-called strip galvanizing plant according to an electrolytic galvanizing process in which galvanic cells connected in series are used.
