Description
R. Sa/SmR. Sa / Sm
Die Erfindung geht aus von einer Wischvorrichtung nach der Gattung des Hauptanspruchs. Bei dieser Wischvorrichtung sind an dem Schwenklagerzapfen und in der Schwenklagerbuchse die Rast- bzw. Gegenrastmittel angeordnet, wodurch die Führungsfläche in dem Gelenk verringert ist. Wegen der unvermeidlichen Fertigungstoleranzen und der im Betrieb der Wischvorrichtung hinzukommenden Abnützung in diesem Gelenk kann das Gelenkspiel relativ bald das zulässige Maß überschreiten, so daß Störungen während des Betriebs der Wischvorrichtung auftreten können..The invention is based on a wiper device according to the preamble of the main claim. In this wiper device are the latching or counter-latching means are arranged on the pivot bearing pin and in the pivot bearing bushing, whereby the guide surface in the joint is reduced. Because of the inevitable Manufacturing tolerances and the additional wear in this joint during operation of the wiper device can do that Joint play relatively soon exceed the permissible level, so that malfunctions during the operation of the wiper device may occur..
Die erfindungsgemäße Wischvorrichtung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß durch die Anordnung eines zusätzlichen Führungszapfens, der in einem besonderen Führungslager geführt ist, die Führungsfläche im Gelenk erheblich vergrößert wird. Dadurch wird die spezifische Belastung im Gelenk verringert und die Lebensdauer und die Betriebssicherheit der Wischanlage erhöht. Als Weiterer Vorteil ist anzusehen, daß durch die erfindungsgemäße Anordnung des Führungszapfens und des Führungslagers die kompakte Bauweise des Schwenkgelenks erhalten bleibt.The wiper device according to the invention with the characterizing features of the main claim has the advantage that by arranging an additional guide pin, which is guided in a special guide bearing, the guide surface in the joint is significantly increased. Through this the specific load in the joint is reduced and the service life and operational reliability of the wiper system are increased. Another advantage is that the arrangement of the guide pin and the guide bearing according to the invention preserves the compact design of the swivel joint remain.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenen Wischvorrichtung möglich.The measures listed in the subclaims are advantageous developments and improvements of the main claim specified wiper device possible.

Zeichnungdrawing
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Die einzige zur Beschreibung gehörende Figur zeigt einen Schnitt durch das Schwenkgelenk, in vergrößerter Darstellung. An embodiment of the invention is shown in the drawing and explained in more detail in the following description. The only figure belonging to the description shows a section through the swivel joint, in an enlarged view.
Wie aus der Figur ersichtlich ist, ist an einem Wischerarm das eine Gelenkteil 12 eines Schwenkgelenks 14 befestigt. Das eine Schwenkgelenk 12 weist eine Schwenklagerbuchse 16 auf, in der ein Schwenklagerzapfen 18 des anderen Gelenkteils 20 geführt ist. Das andere Gelenkteil 20 ist mit einer Aufnahme 22 für ein nicht dargestelltes Wischblatt versehen. Die Schwenklagerbuchse 16 ist mit einer Ringnut 24 ausgestattet, in welche ein Ringwulst 26 des Schwenklagerzapfens 18 eingerastet ist. Auf diese Weise sind die beiden Gelenkteile 12 und 20 so miteinander verbunden, daß sie sich nicht unbeabsichtigt in Richtung der Schwenkachse voneinander lösen können. Um die Führung in dem Schwenkgelenk zu verbessern, weist das eine Gelenkteil 12 einen einstückig mit ihm verbundenen Führungszapfen 28 auf, der in einem Führungslager 30 geführt ist, welches koaxial zur Achse des Schenklagerzapfens 18 in diesem angeordnet ist, so daß der Schwenklagerzapfen 18 einen rohrartigen Querschnitt aufweist.As can be seen from the figure, one joint part 12 of a pivot joint 14 is attached to a wiper arm. That a swivel joint 12 has a swivel bearing bush 16 in which a swivel bearing journal 18 of the other joint part 20 is led. The other joint part 20 is provided with a receptacle 22 for a wiper blade (not shown). The swivel bearing bush 16 is equipped with an annular groove 24 into which an annular bead 26 of the pivot bearing pin 18 is locked. In this way, the two joint parts 12 and 20 are connected to one another that they are not inadvertently in Can solve the direction of the pivot axis from each other. In order to improve the guidance in the pivot joint, one has The joint part 12 has a guide pin 28 which is integrally connected to it and which is guided in a guide bearing 30, which is arranged coaxially to the axis of the pivot bearing pin 18 in this, so that the pivot bearing pin 18 is tubular Has cross section.
Die Lagerung des Schwenkgelenks wird also nicht nur durch den Schwenklagerzapfen 18 und die diesem zugeordnete Schwenklagerbuchse 16 bewirkt, sondern auch durch den passend in dem Führungslager 30 geführten Führungszapfen 28. Auf diese Weise ist die tragende und führende Gelenkfläche erheblich vergrößertThe mounting of the swivel joint is therefore not only provided by the swivel bearing pin 18 and the swivel bearing bush assigned to it 16, but also by the guide pin 28 suitably guided in the guide bearing 30. In this way the supporting and leading articular surface is considerably enlarged

und damit die spezifische Belastung der Gelenkflächen verringert worden, wodurch die Abnützung der Gelenkteile entscheidend vermindert wird.and thus the specific load on the joint surfaces has been reduced, which makes the wear and tear of the joint parts decisive is decreased.
Weiter weist das Schwenkgelenk 14 eine Torsionsfeder 32 auf, die in montiertem Zustand vorgespannt den Schwenklagerzapfen 18 umgibt und deren eines Ende in dem einen Gelenkteil und deren anderes Ende in dem anderen Gelenkteil 20 verankert sind. Die Torsionsfeder 32 liegt in einem Raum J>k, der durch einen stufenförmigen Absatz 36 im Gelenkteil 12 und durch eine stirnseitige Nut 38 im Gelenkteil 20 gebildet ist.The pivot joint 14 also has a torsion spring 32 which, in the assembled state, surrounds the pivot bearing pin 18 in a pretensioned manner and one end of which is anchored in one joint part and the other end in the other joint part 20. The torsion spring 32 lies in a space J> k, which is formed by a stepped shoulder 36 in the joint part 12 and by an end-face groove 38 in the joint part 20.
Die Wischvorrichtung kann wahlweise mit oder ohne Torsionsfeder montiert sein. Die Torsionsfeder hat den Zweck, daß die beiden Gelenkteile 12 und 20 bzw. der Wischerarm 10 und das nicht dargestellte Wischblatt in einer vorbestimmten Stellung gehalten sind, aus der eine Schwenkbewegung des Wischblatts entgegen der Spannung der Torsionsfeder 32 möglich ist.The wiper device can optionally be mounted with or without a torsion spring. The torsion spring has the purpose that the two joint parts 12 and 20 or the wiper arm 10 and the wiper blade, not shown, in a predetermined Position are held from which a pivoting movement of the wiper blade against the tension of the torsion spring 32 is possible.
