Description
Die Erfindung betrifft ein Kugelgelenk, welches im Wesentlichen durch ein Bauteil mit einer Kugel die in einem Gehäuse schwenkbar gelagert ist, gebildet wird und welches insbesondere in Fahrwerken von Kraftfahrzeugen einsetzbar ist.The invention relates to a ball joint, which is essentially formed by a component with a ball which is pivotally mounted in a housing, and which is used in particular in chassis of motor vehicles.
Es ist bekannt, zwischen der Kugel und dem angrenzenden Gehäuse Schmiermittelschichten zur Verbesserung der Gleiteigenschaften vorzusehen, wobei auch die Kugel des Bauteils mit einer Beschichtung versehen sein kann, die das Gleitverhalten der Kugel im Gehäuse verbessert.It is known to provide between the ball and the adjacent housing lubricant layers to improve the sliding properties, wherein the ball of the component may be provided with a coating which improves the sliding behavior of the ball in the housing.
In der
Aus
Die Herstellung dieser bisher verwendeten Gleitschichten ist relativ aufwendig und die Lebensdauer dieser Kugelgelenke ungenügend.The preparation of these previously used sliding layers is relatively expensive and the life of these ball joints insufficient.

Die Druckschriften
Die Verwendung von Zink-Nickel-Beschichtungen als Gleitschicht bei Kugelgelenken ist bisher nicht bekannt.The use of zinc-nickel coatings as a sliding layer in ball joints is not yet known.
Aufgabe der Erfindung ist es, ein Kugelgelenk zu entwickeln, welches einfach und kostengünstig herstellbar ist und eine hohe Lebensdauer sowie gute Gleiteigenschaften aufweist.The object of the invention is to develop a ball joint which is simple and inexpensive to produce and has a long service life and good sliding properties.
Diese Aufgabe wird durch die Merkmale des ersten Schutzanspruchs gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.This object is solved by the features of the first patent claim. Advantageous embodiments emerge from the subclaims.
Das Kugelgelenk, welches insbesondere für ein Fahrwerk eines Kraftfahrzeuges Anwendung findet, weist ein Bauteil mit einer Kugel auf, die in einem Gehäuse oder in einer im Gehäuse angeordneten Lagerschale schwenkbar gelagert ist, wobei das Bauteil erfindungsgemäß zumindest an seiner Kugel eine Beschichtung aus Zink oder eine Zink enthaltenden Beschichtung aufweist. Es wurde überraschender Weise festgestellt, dass durch diese Beschichtung der Kugel des Bauteils, die hier als Gleitschicht und Verschleißschutzschicht wirkt, hervorragende Gleiteigenschaften bei einer hohen Lebensdauer erzielt werden.The ball joint, which is used in particular for a chassis of a motor vehicle application, has a component with a ball which is pivotally mounted in a housing or in a housing bearing shell, wherein the component according to the invention at least on its ball a coating of zinc or a Having zinc-containing coating. It has surprisingly been found that this coating of the ball of the component, which acts as a sliding layer and wear protection layer, excellent sliding properties are achieved with a long service life.
Als besonders vorteilhaft hat sich dabei eine Zink-Nickel-Schicht erwiesen, wobei jedoch auch eine Beschichtung in Form einer Zink-Eisen-Schicht oder eine Zink-Eisen-Nickel-Schicht möglich ist.A zinc-nickel layer has proven to be particularly advantageous, although a coating in the form of a zinc-iron layer or a zinc-iron-nickel layer is also possible.
Vorteilhaft kann es dabei weiterhin sein, wenn die Beschichtung z. B. mit Gleitlack versiegelt und/oder passiviert ist.It may also be advantageous if the coating z. B. sealed with lubricating varnish and / or passivated.
Es ist ebenfalls möglich, die Beschichtung zu polieren und/oder mechanisch zu verfestigen.It is also possible to polish and / or mechanically strengthen the coating.
Gemäß einer Variante der Erfindung wird zumindest die Kugel des Kugelzapfens mit einer Beschichtung aus einem sauren Elektrolyt, insbesondere in Form einer Zink-Nickel-Schicht aus einem sauren Elektrolyt, versehen.According to a variant of the invention, at least the ball of the ball stud is provided with a coating of an acidic electrolyte, in particular in the form of a zinc-nickel layer of an acidic electrolyte.
Vorteilhafter Weise kann auch das gesamte Bauteil entsprechend beschichtet werden, wobei die Beschichtung an der Kugel als Gleitschicht und Verschleißschutzschicht und am restlichen Bauteil als Korrosionsschutzschicht wirkt.Advantageously, the entire component can be coated accordingly, wherein the coating acts on the ball as a sliding layer and wear protection layer and the rest of the component as a corrosion protection layer.
Insbesondere saure Zink-Nickel-Schichten weisen dabei eine harte und sehr glatte Oberfläche ohne Knospenbildung und ohne Oberflächenversprödung auf, wodurch insgesamt die Gleiteigenschaften im Vergleich zu herkömmlichen Lösungen erheblich verbessert werden und der Verschleiß reduziert wird.In particular, acidic zinc-nickel layers have a hard and very smooth surface without bud formation and without embrittlement on the surface, as a result of which the sliding properties in comparison with conventional solutions be significantly improved and the wear is reduced.
Das Bauteil kann z. B. in Form eines Kugelzapfens oder auch in Form einer Kugelstange ausgebildet sein.The component can, for. B. in the form of a ball stud or in the form of a ball bar.
Mit der erfindungsgemäßen Lösung wird ein einfach und kostengünstig herstellbares Kugelgelenk geschaffen, welches hervorragende Gleiteigenschaften bei einer hohen Lebensdauer aufweist.With the solution according to the invention a simple and inexpensive to produce ball joint is created, which has excellent sliding properties with a long life.
Die Erfindung wird nachfolgend an einem Ausführungsbeispiel und einer zugehörigen Zeichnung näher erläutert.The invention is explained in more detail below using an exemplary embodiment and an associated drawing.
Die Zeichnung zeigt einen Längsschnitt durch ein Kugelgelenk, welches ein Bauteil
Das Bauteil
Diese Beschichtung
Dabei wurde überraschender Weise festgestellt, dass insbesondere mit der Werkstoffpaarung POM und Beschichtung aus saurer Zink-Nickel-Legierung die hervorragenden Gleiteigenschaften bei hoher Verschleißfestigkeit zu verzeichnen waren, da eine derartige Materialkombination bisher nicht üblich war.It was surprisingly found that in particular with the material pairing POM and coating of acidic zinc-nickel alloy, the excellent sliding properties were recorded with high wear resistance, since such a combination of materials was not common practice.
Gemäß eines nicht dargestellten Ausführungsbeispiels ist es auch möglich, nur die Kugel, bzw. nur den Bereich der Kugel, der in der Lagerschale gleitet, mit der Beschichtung zu versehen.According to an embodiment not shown, it is also possible to provide only the ball, or only the region of the ball which slides in the bearing shell, with the coating.
Es ist ebenfalls gemäß nicht dargestellter Varianten möglich, auch andere Bauteile, die eine entsprechende Kugel aufweisen und mit der Kugel in einem Gehäuse zur Bildung eines Kugelgelenkes gelagert sind, nahezu vollständig oder nur im Bereich der Kugel mit der Beschichtung zu versehen.It is also possible according to variants not shown, also other components having a corresponding ball and are mounted with the ball in a housing to form a ball joint, almost completely or only in the sphere to be provided with the coating.
