Description
Radmuttern und Radschrauben Wheel nuts and wheel bolts
Die vorliegende Erfindung betrifft Radschrauben beziehungsweise Radmuttern mit einer Oberflächenbeschichtung, die als Korrosionsschutz dient.The present invention relates to wheel bolts or wheel nuts having a surface coating which serves as corrosion protection.
Gemäß dem Stand der Technik wird derzeit als Oberflächenbeschichtung für solche Radmuttern oder Radschrauben das Produkt Dacromet 320 B + PLUS L für Radschrauben beziehungsweise Radmuttern verwendet. Dieses Produkt entspricht jedoch nicht der EU-Altautodirektive 2000/53/EG, gemäß der alle Nutz- fahrzeuge bis 3,5 Tonnen, welche ab 01.07.2007 in Verkehr gebracht werden, Cr6-frei sein müssen.According to the prior art, the product Dacromet 320 B + PLUS L is currently used for wheel bolts or wheel nuts as a surface coating for such wheel nuts or wheel bolts. However, this product does not comply with the EU End-of-Life Directive 2000/53 / EC, according to which all commercial vehicles up to 3.5 tonnes, which are to be placed on the market from 01.07.2007, must be Cr6-free.
Es ist daher Aufgabe der vorliegenden Erfindung, eine neue Oberflächenbeschichtung für Radmuttern und Radschrauben zu schaffen, welche die gesetzliche Anforderung der Cr6-freiheit erfüllt und dennoch die schon bisher existierenden Anforderungen der Autoindustrie hinsichtlich Felgenreinigerbeständigkeit, Mehr- fachverschraubung gegen AIu- und Stahlfelge sowie Salzsprühnebelprüfung mit/ohne Wärmeauslagerung sowie bezüglich des Warmlöseverhaltens erfüllt.It is therefore an object of the present invention to provide a new surface coating for wheel nuts and wheel bolts, which meets the legal requirement of Cr6-freedom and yet the already existing requirements of the auto industry in terms of rim cleaning resistance, multiple screw against AIU and steel rim and salt spray with / fulfilled without heat aging and with respect to the heat release behavior.
Erfindungsgemäß wird diese Aufgabe durch Radmuttern und Radschrauben gelöst, die eine Oberflächenbeschichtung aufweisen, die aus einem Zinklamellenüberzug als Basecoat und einem Gleitlack als Topcoat aufgebaut ist.According to the invention, this object is achieved by wheel nuts and wheel bolts, which have a surface coating which is constructed from a zinc flake coating as a basecoat and a lubricating paint as a topcoat.
Besonders bevorzugt ist es dabei, dass der Basecoat zu 60-80 % aus einem Zink- lamellenüberzug und zu 5-15 % aus Aluminiumlamellen Silber und schwarz besteht.
Der Topcoat besteht vorzugsweise aus einem Gleitlack mit organischen und anorganischen Komponenten.It is particularly preferred that the basecoat consists of 60-80% of a zinc-lamella coating and 5-15% of aluminum fins silver and black. The topcoat preferably consists of a bonded coating with organic and inorganic components.
Gemäß der vorliegenden Erfindung werden Radmuttern und Radschrauben ge- schaffen, die mit einer speziellen Oberflächenbeschichtung versehen sind, die aus einem Basecoat und einem Topcoat besteht.According to the present invention, wheel nuts and wheel bolts are provided which are provided with a special surface coating consisting of a basecoat and a topcoat.
Der Basecoat besteht dabei aus 70 % Zinklamellenüberzug mit bis zu 10 % Aluminiumlamellen Silber und schwarz.The basecoat consists of 70% zinc flake coating with up to 10% aluminum fins silver and black.
Als Topcoat findet ein Gleitlack mit organischen und anorganischen Komponenten Verwendung.The topcoat is a bonded coating with organic and inorganic components.
Mit der erfindungsgemäß vorgeschlagenen Cr6-freien Kombination eines Zinkla- mellenüberzugs mit einem geeigneten Gleitlack werden sämtliche Anforderungen an die Radschrauben beziehungsweise der Radmuttern erfüllt:With the Cr6-free combination of a zinc flake coating proposed by the invention with a suitable anti-friction paint, all the requirements for the wheel bolts or the wheel nuts are met:
1. Cr6-freiheit1. Cr6-freedom
2. Felgenreinigerbeständigkeit (Simulationsprüfung für das Verhalten in sauren Lösungen)2. Rim cleaner resistance (simulation test for behavior in acidic solutions)
3. Mehrfachverschraubung gegen AIu- und Stahlfelge (mit Vorspannkräften von 30-55 kN)3. Multiple screwed connection against aluminum and steel rim (with preload forces of 30-55 kN)
4. Salzsprühnebelprüfung mit und/ohne Wärmeauslagerung (180°C bei 96h) mindestens 720h ohne Eisenkorrosion 5. Warmlöseverhalten
4. Salt spray test with and / or without heat aging (180 ° C at 96h) at least 720h without iron corrosion 5. Heat dissipation behavior
