Abstract
Description
Die Erfindung betrifft ein korrosionsgeschütztes Wischerwellenlager für einen Scheibenwischer an einem Kraftfahrzeug.The The invention relates to a corrosion-protected wiper shaft bearing for a Windscreen wiper on a motor vehicle.
Die Antriebswellen (Wischerwellen) für die Scheibenwischer an einem Kraftfahrzeug sind üblicherweise in einem Gleitlager innerhalb der Fahrzeugkarosserie gelagert und mit einer Wellendurchführung nach der Außenseite der Fahrzeugkarosserie geführt, wobei das Gleitlager aus einem Lagergehäuse (Lagerkörper), insbesondere aus Aluminium, und wenigstens einer in diesem angeordneten Lagerbuchse gebildet ist, in der die Wischerwelle drehbar angeordnet ist. Die Wischerwellen sind einer Beaufschlagung durch Regen, Spritzwasser und Scheibenreinigungsmittel ausgesetzt. Daher muss die Gleitlagerung abgedichtet werden, um zu verhindern, dass Feuchtigkeit oder Schmutz in axialer Richtung in das Gleitlager gelangen.The Drive shafts (wiper shafts) for The windscreen wipers on a motor vehicle are usually in a plain bearing stored within the vehicle body and with a shaft passage to the outside guided the vehicle body, wherein the sliding bearing consists of a bearing housing (bearing body), in particular aluminum, and at least one bushing arranged in this is formed, in which the wiper shaft is rotatably arranged. The wiper waves are subject to rain, splashing water and window cleaning agents exposed. Therefore, the plain bearing must be sealed to to prevent moisture or dirt in the axial direction get into the plain bearing.
Dazu ist bekannt, den zwischen der Wischerwelle und dem Lagerkörper gegebenen Ringspalt an dessen beiden Enden mit jeweils einem O-Ring und mit einer Scheibe abzudichten und mit einer Fettfüllung zu versehen. Die O-Ringe haben jedoch infolge des auftretenden Verschleißes eine nur begrenzte Standzeit. Eindringende Feuchtigkeit führt dadurch insbesondere zu einer Korrosion des aus Aluminium bestehenden Lagerkörpers, verbunden mit einem Aufblühen des Aluminiums im Ringspalt außerhalb des Anordnungsbereiches der wenigstens einen Lagerbuchse, und kann zu einem Eindringen von Korrosionsprodukten in den Spalt zwischen der Lagerbuchse und der Wischerwelle führen, mit der Folge, dass das Wischerwellenlager zerstört wird.To is known, given between the wiper shaft and the bearing body Annular gap at both ends, each with an O-ring and with To seal a disc and provide it with a grease. The O-rings However, due to the wear occurring only a limited life. Ingress of moisture leads characterized in particular to a corrosion of the existing aluminum Bearing body, connected with a blossoming of the aluminum in the annular gap outside the Arrangement range of at least one bearing bush, and may a penetration of corrosion products into the gap between the Bearing bush and the wiper shaft lead, with the result that the Wiper shaft bearing destroyed becomes.

Es ist Aufgabe der Erfindung, ein korrosionsgeschütztes Wischerwellenlager nach dem Oberbegriff des Anspruchs 1 so zu gestalten, dass eine Korrosion des Lagerkörpers im Bereich eines zwischen diesem und der Antriebswelle gegebenen Ringspaltes mit einfachen Mitteln weitestgehend unterbunden ist.It Object of the invention, a corrosion-protected wiper shaft bearing after to make the preamble of claim 1 so that a corrosion of the bearing body in the range of between this and the drive shaft given Annular gap is largely prevented by simple means.
Diese Aufgabe wird bei einem korrosionsgeschützten Wischerlager nach dem Oberbegriff des Anspruchs 1 durch dessen kennzeichnende Merkmale gelöst. Vorteilhafte Ausgestaltungen sind in den nachfolgenden Unteransprüchen beschrieben.This object is achieved in a corrosion-proof wiper bearing according to the preamble of claim 1 by its characterizing features. Advantageous embodiments are in the described below subclaims.
Die Erfindung besteht in einem korrosionsgeschützten Wischerwellenlager für einen Scheibenwischer an einem Fahrzeug, das in bekannter Weise einen Lagerkörper und wenigstens eine in diesem angeordnete Lagerbuchse für eine Wischerwelle sowie einen zwischen der Lagerbuchse, dem Lagerkörper und der Wischerwelle gebildeten Ringspalt aufweist, der Lagerkörper erfindungsgemäß wenigstens im Bereich des Ringspaltes mit einer Korrosionsschutzschicht, insbesondere jedoch mit einer Kunststoffbuchse, ausgekleidet ist. Durch diese Maßnahme wird eine Korrosion des Lagerkörpers verhindert und damit sichergestellt, dass keine Korrosionsprodukte zwischen die Lagerbuchse und die Wischerwelle gelangen und das Wischerwellenlager zerstören. Der Einsatz einer Kunststoffbuchse als Korrosionsschutzmaßnahme ist technologisch kostengünstig. Es hat sich gezeigt, dass weitere Dichtungsmittel, wie O-Ringe, eine Vollfettfüllung des Ringspaltes und eine Abdeckkappe im Bereich des wischerarmseitigen Austritts der Wischerwelle aus dem Lagerkörper entfallen können. Zur Erhöhung des Schutzes des Wischerwellenlagers gegenüber Verschmutzung ist es jedoch sinnvoll, diese Mittel einzeln oder in ihrer Gesamtheit auch weiterhin anzuordnen.The Invention consists in a corrosion-protected wiper shaft bearing for a Windscreen wiper on a vehicle in a known manner a bearing body and at least one arranged in this bushing for a wiper shaft and one formed between the bearing bush, the bearing body and the wiper shaft Annular gap, the bearing body According to the invention at least in Area of the annular gap with a corrosion protection layer, in particular however, with a plastic bushing, lined. Through this measure is a corrosion of the bearing body prevents and thus ensures that no corrosion products get between the bearing bush and the wiper shaft and the wiper shaft bearing to destroy. The use of a plastic bushing as a corrosion protection measure is technologically cost-effective. It has been found that other sealants, such as O-rings, a full fat filling of the annular gap and a cap in the wiper arm side Outlet of the wiper shaft can be omitted from the bearing body. to increase However, it is the protection of the wiper shaft bearing against pollution It makes sense to continue to use these funds individually or in their entirety to arrange.
Der Lagerkörper kann alternativ auch auf seiner gesamten Länge oder im wesentlichen auf seiner gesamten Länge mit einer Kunststoffbuchse ausgekleidet sein, so dass die wenigstens eine Lagerbuchse auf der Kunststoffbuchse angeordnet ist.Of the bearing body Alternatively, it can also be applied over its entire length or substantially his entire length be lined with a plastic bushing so that the at least a bearing bush is arranged on the plastic bushing.
Am wischerarmseitigen Austritt aus dem Lagerkörper ist die Wischerwelle vorteilhaft mit einer Ringnut versehen, in die ein am Lagerkörper abgestützter Sprengring eingreift. Im Zusammenwirken mit einer Federscheibe, die an einem fahrzeugseitig fest mit der Wischerwelle verbundenen Schwinghebel abgestützt ist, der die Wischerwelle oszillierend antreibt, wird die Wischerwelle durch diesen Sprengring in einer definierten axialen Position am Lagerkörper gehalten.At the Wischerarmseitigen outlet from the bearing body, the wiper shaft is advantageous provided with an annular groove, in which engages a supported on the bearing body snap ring. In cooperation with a spring washer, fixed to a vehicle side is supported with the wiper shaft connected rocker arm, which drives the wiper shaft in an oscillating manner, becomes the wiper shaft by this snap ring in a defined axial position on bearing body held.
Die Erfindung wird nachstehend an zwei Ausführungsbeispielen erläutert. In den zugehörigen Zeichnungen zeigen:The Invention will be explained below with reference to two embodiments. In the accompanying drawings demonstrate:
