Description

Die Erfindung bezieht sich auf. ein Kreuz- oder Kardangelenk, insbesondere für einen Kardanwellenantrieb für Kraftfahrzeuge, der mit einem sternförmigen Kupplungsglied versehen ist, dessen Arme sich über Nadellager mit diametral gegenüberliegenden Paaren von äußeren Laufringen im Eingriff befinden, die von dem treibenden bzw. dem angetriebenen Gabelkopf getragen werden, wobei das innere Ende des Laufringes mit einem metallischen oder einem anderen festen Stützelement für die Nadeln versehen ist.The invention relates to. a cross or cardan joint, in particular for a cardan shaft drive for motor vehicles with a star-shaped coupling member is provided, the arms of which are diametrically opposed to needle roller bearings Pairs of outer races are engaged, which are engaged by the driving or the driven clevis, with the inner end of the raceway provided with a metallic or other solid support element for the needles is.

Um das Nadellager gegen das Eindringen von Schmutz od. dgl. zu schützen, hat man bereits vorgeschlagen, eine Dichtung vorzusehen, die aus einem Metallring, der sich gegen ein Widerlager auf dem zugehörigen Arm des Kupplungsgliedes anlegt, und einer in dem Metallring untergebrachten Dichtung besteht, wobei der Metallring mit einem Flansch ausgestattet ist, der mit geringem radialem Abstand das angrenzende Ende des 'zugehörigen Stützelements für die Nadeln umfaßt.To protect the needle bearing against the ingress of dirt or the like, it has already been proposed to provide a seal consisting of a metal ring, which rests against an abutment on the associated arm of the coupling link, and a seal housed in the metal ring, the metal ring is equipped with a flange with a small radial distance from the adjacent Includes end of the 'associated support element for the needles.

Die Erfindung hat sich die Aufgabe gestellt, Dichtungsmittel zu schaffen, die bei einem Füllen der Nadellager mit Schmiermittel ein Entweichen der dabei verdrängten Luft durch die Dichtung ermöglicht, ohne deren Dichtungseigenschaften zu beeinträchtigen.The invention has set itself the task of creating sealants, which, when the needle roller bearings are filled with lubricant, allow the displaced to escape Air allows through the seal without affecting its sealing properties.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der aus Gummi od. dgl. bestehende Dichtungsring einen ringförmigen Flansch aufweist, der unter Druck mit einem ringförmigen Teil der angrenzenden Stirnfläche des Stützelements im Eingriff steht und näher an dem Flansch des Metallringes liegt als an dem angrenzenden Teil des zugehörigen Kupplungsarmes.This object is achieved in that the rubber Od. The like. Existing sealing ring has an annular flange, which under Pressure with an annular part of the adjacent end face of the support element engages and is closer to the flange of the metal ring than to the adjacent one Part of the associated coupling arm.

Die Erfindung ist in der Zeichnung beispielsweise veranschaulicht und im nachstehenden an Hand dieser Zeichnung im einzelnen beschrieben.The invention is illustrated in the drawing, for example and described in detail below with reference to this drawing.

Fig. I zeigt im. vergrößerten Maßstab die Ansicht eines Teilschnittes, die eine Form einer erfindungsgemäßen Dichtung für die Nadellager eines Kardangelenkes zeigt; Fig. a zeigt eine ähnliche Teilansicht der zusammengedrückten Dichtung allein, während Fig.3 als Vergleich dieselbe Dichtung ohne Spannung zeigt.Fig. I shows im. enlarged scale the view of a partial section, one form of a seal according to the invention for the needle roller bearings of a universal joint shows; Fig. A shows a similar partial view of the compressed seal alone, while FIG. 3 shows the same seal without tension as a comparison.

In der Zeichnung ist mit der Bezugsziffer I2 ein Teil eines Bügels eines Kardangelenkes bezeichnet, in dem eine Kappe I3 angebracht ist, die den äußeren Laufring I4 eines Nadellagers 15 bildet, dessen innere Lauffläche von dem äußeren Ende I6 eines der Kupplungsarme I7 des Gelenkes gebildet wird. Die nach innen zeigenden Enden der Nadeln werden innerhalb des Laufringes I4 durch ein Stützelement I8 in ihrer Stellung gehalten, das mit Preßpassung in das angrenzende Ende des Laufringes I4 eingesetzt ist und das mit einem Flansch I9 versehen ist, durch den seine Einwärtsbewegung auf .eine bestimmte gewünschte Tiefe begrenzt ist. Auf dem Kupplungsarm 17 befindet sich ein ringförmiges Widerlager oder eine Schulter 2I, das einen Metallring 22 trägt, der ungefähr um 9o° gebogen ist und der einen Flansch 23 aufweist, der die Außenseite des angrenzenden Endes des Stützelements I8 mit radialem Spiel umfaßt. Dieser Ring 22, der in einfacher Weise als Preßteil hergestellt sein kann, bildet eine Aufnahme für einen Gummidichtring 25, der sich unter leichter radialer Spannung befindet und einem stärkeren axialen Druck unterworfen ist, durch den ein Flansch 26 dieses Ringes gegen einen ringförmigen Teil der angrenzenden Endfläche des Stützelements gedrückt wird, so daß eine vollkommene Dichtung erreicht wird. Ein Vergleich der Fig. 2 und 3 gibt die Größe des Axialdruckes durch den Unterschied in der axialen Länge des Flansches 26 wieder.In the drawing, the reference number I2 denotes part of a bracket of a cardan joint, in which a cap I3 is attached, the outer Forms race I4 of a needle bearing 15, the inner running surface of the outer At the end of I6 one of the coupling arms I7 of the joint is formed. The ones pointing inwards Ends of the needles are secured within the raceway I4 by a support element I8 in held in place with an interference fit into the adjacent end of the raceway I4 is inserted and which is provided with a flange I9 through which its inward movement is limited to a certain desired depth. Located on the coupling arm 17 an annular abutment or shoulder 2I, which has a metal ring 22 carries, which is bent about 9o ° and which has a flange 23 which Outside of the adjacent end of the support member I8 includes radial play. This ring 22, which can be produced in a simple manner as a pressed part, forms a receptacle for a rubber sealing ring 25, which is under slight radial tension is located and is subjected to a stronger axial pressure, through which a flange 26 of this ring against an annular part of the adjacent end face of the support element is pressed so that a perfect seal is achieved. A comparison of the Fig. 2 and 3 give the size of the axial pressure by the difference in the axial Length of the flange 26 again.

In dem Kupplungsarm 17 befindet sich eine Bohrung 28, durch die der Endfläche 29 der Kappe Schmiermittel zugeführt werden kann, das von dort zum Nadellager 15 gelangt.- Wenn das Nadellager mit Schmiermittel versorgt wird, wird der Flansch 26 radial nach außen gedrückt, so daß die Luft über den radialen Zwischenraum zwischen dem- Flansch 23 und der angrenzenden äußeren Umfangsfläche des Stützelements entweichen kann.In the coupling arm 17 there is a bore 28 through which the end face 29 of the cap can be supplied with lubricant, which from there reaches the needle bearing 15. When the needle bearing is supplied with lubricant, the flange 26 is pressed radially outward so that the air can escape via the radial space between the flange 23 and the adjoining outer peripheral surface of the support element.
