Abstract
Description
Die vorliegende Erfindung betrifft eine Scheibenwischvorrichtung, insbesondere für ein Kraftfahrzeug, mit mindestens einem an einer Fahrzeugkarosserie befestigten Wischerlager, in dem jeweils mindestens eine Lagerwelle gelagert ist, an der eine Lagerplatte vorgesehen ist, um im Wischbetrieb auftretende Kräfte und Momente aufzunehmen und weiterzuleiten, wobei an der Lagerplatte mindestens ein Kugelzapfen vorgesehen ist.The present invention relates to a windshield wiper device, in particular for a motor vehicle, with at least one mounted on a vehicle body wiper bearing, in each of which at least one bearing shaft is mounted on which a bearing plate is provided to receive and forward forces and moments occurring in wiping operation, wherein the bearing plate is provided at least one ball stud.
Derartige Scheibenwischvorrichtungen sind allgemein bekannt. Die Kugelzapfen können als Einfach- oder Doppelkugelzapfen ausgeführt sein und werden meist aus Stahl häufig mit verknickter Oberfläche hergestellt. Dazu werden die Kugelzapfen entweder einem Drehprozess oder einer Kaltumformung unterzogen. Anschließend werden die Kugelzapfen über einen Taumelnietprozess an der Lagerplatte bzw. einer Motorkurbel fixiert.Such windshield wiper devices are well known. The ball pins can be designed as single or double ball pivot and are usually made of steel often with kinked surface. For this purpose, the ball pins are subjected to either a turning process or a cold forming. Subsequently, the ball pins are fixed by a Taumelnietprozess on the bearing plate or a motor crank.
Die Herstellung des Kugelzapfens erweist sich als relativ aufwendig. Auch die Montage des Kugelzapfens an der Lagerplatte ist zeit- und kostenintensiv. The production of the ball stud proves to be relatively expensive. The installation of the ball stud on the bearing plate is time consuming and costly.
Offenbarung der ErfindungDisclosure of the invention
Es ist daher Aufgabe der vorliegenden Erfindung, eine Scheibenwischvorrichtung bereitzustellen, die einfach und kostengünstig herstellbar und montierbar ist.It is therefore an object of the present invention to provide a windshield wiper device that is simple and inexpensive to manufacture and assemble.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Kugelzapfen zur Befestigung an der Lagerplatte einen selbstschneidenden bzw. selbstfurchenden Gewindebereich aufweist sowie eine sich an den Gewindebereich anschließende Anschlagfläche zur Begrenzung der axialen Bewegung des Kugelzapfens in die Lagerplatte.This object is achieved in that the ball pin for attachment to the bearing plate has a self-tapping or self-tapping threaded portion and an adjoining the threaded portion stop surface for limiting the axial movement of the ball stud in the bearing plate.
Vorteile der ErfindungAdvantages of the invention
Mit anderen Worten weist die erfindungsgemäße Scheibenwischvorrichtung einen Kugelzapfen auf, der aufgrund des selbstfurchenden Gewindebereichs und der sich an den Gewindebereich anschließenden Anschlagfläche sehr genau positioniert und einfach montiert werden kann. Der im Stand der Technik schwer zu beherrschende Taumelnietprozess wird so durch einen einfachen Schraubprozess ersetzt, wodurch die Montagekosten erheblich reduziert und die Zuverlässigkeit der Verbindung zwischen Lagerplatte und Kugelzapfen gesteigert werden können. In other words, the windshield wiper device according to the invention has a ball stud, which can be positioned very accurately and simply mounted due to the self-tapping threaded portion and the abutment surface adjoining the threaded portion. The Taumelnietprozess difficult to master in the art is thus replaced by a simple screwing, whereby the assembly costs can be significantly reduced and the reliability of the connection between the bearing plate and ball stud can be increased.
Der Kugelzapfen kann zur Montage in die Lagerplatte in ein in der Lagerplatte vorgestanztes Bohrloch oder eine Körnung eingeschraubt werden, bis der Kugelzapfen mit dem Anschlag an der Lagerplatte zur Anlage gelangt. Dabei schneidet der selbstfurchende Gewindebereich automatisch ein Gewinde in die Lagerplatte oder Motorkurbel, wodurch sich eine lösbare Verbindung zwischen der Lagerplatte und dem Kugelzapfen einstellt. Es ist somit nicht mehr notwendig, vorab ein Gewinde in die Lagerplatte oder Motorkurbel zu schneiden.The ball pin can be screwed for mounting in the bearing plate in a pre-punched in the bearing plate hole or a grain until the ball pin comes to rest with the stop on the bearing plate. The self-tapping threaded portion automatically cuts a thread in the bearing plate or motor crank, creating a releasable connection between the bearing plate and the ball pivot. It is therefore no longer necessary to pre-cut a thread in the bearing plate or engine crank.
In einem weiteren Ausführungsbeispiel ist zur Vereinfachung der Montage in dem Kugelzapfen eine Werkzeugaufnahme vorgesehen, um den Kugelzapfen mittels eines Werkzeuges in die Lagerplatte einzutreiben.In a further embodiment, a tool holder is provided to simplify the assembly in the ball stud to drive the ball pin by means of a tool in the bearing plate.
Es hat sich als besonders zweckmäßig erwiesen, wenn die Werkzeugaufnahme so ausgebildet ist, dass sie nach der Montage des Kugelzapfens an der Lagerplatte als eine Art Fetttasche zur Schmierung des Kugelzapfens dient.It has proved to be particularly useful when the tool holder is designed so that it serves as a kind of grease pocket for the lubrication of the ball stud after mounting the ball stud on the bearing plate.
Die Werkzeugaufnahme kann beispielsweise ein Torx oder ein Torxplus oder aber auch ein Innensechskant sein. Alternativ ist es auch möglich, oberhalb eines Kugelbereichs des Kugelzapfens einen Vorsprung beispielsweise in der Form eines Sechskants vorzusehen, auf welchen das Eintreibwerkzeug wie beispielsweise eine Nuss aufgeschoben werden kann.The tool holder may for example be a Torx or a Torxplus or even a hexagon socket. Alternatively, it is also possible, above a spherical region of the ball stud, to provide a projection, for example in the form of a hexagon, on which the driving tool, for example a nut, can be pushed.
In einem weiteren Ausführungsbeispiel der vorliegenden Erfindung ist der Kugelzapfen aus Kunststoff ausgebildet. Dadurch wird es möglich, den Kugelzapfen beispielsweise durch einen Spritzgussprozess herzustellen. Ein aufwendiger Drehprozess kann so entfallen. ferner kann so auf einfache und reproduzierbare Weise der Kugelzapfen als Einfach- oder Doppelkugelzapfen ausgebildet werden.In a further embodiment of the present invention, the ball stud is made of plastic. This makes it possible to produce the ball stud, for example, by an injection molding process. A complex turning process can be omitted. Furthermore, it can be formed as a single or double ball pin in a simple and reproducible manner, the ball pin.
Zur besseren Abstützung des Kugelzapfens an der Lagerplatte oder Motorkurbel ist in einem Ausführungsbeispiel vorgesehen, einen Tellerbund als Anschlag an dem Kugelzapfen auszubilden.For better support of the ball stud on the bearing plate or motor crank is provided in one embodiment, form a plate collar as a stop on the ball stud.
Um Verschleiß aufgrund von Reibung zu verringern oder sogar zu vermeiden, ist in einem weiteren Ausführungsbeispiel der vorliegenden Erfindung eine Mantelfläche des Kugelzapfens zumindest bereichsweise oder vollständig beschichtet.In order to reduce wear due to friction or even to avoid, in a further embodiment of the present invention, a lateral surface of the ball stud at least partially or completely coated.
Eine weitere Möglichkeit, die Lebensdauer und Zuverlässigkeit der erfindungsgemäßen Scheibenwischvorrichtung zu erhöhen besteht darin, an dem Kugelzapfen eine Verliersicherung insbesondere im Gewindebereich des Kugelzapfens vorzusehen. Another way to increase the life and reliability of the windshield wiper device according to the invention is to provide on the ball pivot a captive especially in the threaded portion of the ball stud.
Eine solche Verliersicherung kann beispielsweise durch einen mikroverkapselten Klebstoff gebildet sein.Such a captive can be formed for example by a microencapsulated adhesive.
