Bei solchen Kugelgelenkverbindungen ist ·■ übliohe Praxis, eine nachgiebige Kappe zu verwenden, um das Eindringen ron Schmutz und/oder Feuchtigkeit in dae Innere der Kappe zu yemeiden und eine Beschädigung der Lagerfläohen ron Kugel und Pfanne su verhindern. Dieae Abdichtung ist insbesondere bei Kugelgelenkverbindungen notwendig, bei denen die Lagerbüchsen, welche normalerweise zwischen den Lagerfläohen von Kugel und Pfanne vorgesehen sind, aus Kunststoff bestehen, wie sie beispielsweise in sogenannten fettlosen Gelenken (Gelenke, die nicht abgesohmiert werden! vorgesehen sind. Die naohgibeigen Kappen bestehen aus Natur- oder Kunstgummi oder aus anderen geeigneten Elastomeren! Jedoch ist es schwierig, eine Diohtungskappe zu schaffen, die das Eindringen von So haut* und «asser Über die gesamte zu erwartende Lebensdauer der Verbindung hinweg verhindert. Ea ist bekannt, durch Füllen des Kappeninneren mit Fett einen Auffang für Schmutz und Wasser su schaffen. Erfahrungsgemäß treten jedoch Schwierigkeiten beim Befestigen einsr mit Fett gefüllten Kappe auf, und es ist Aufgabe der Erfindung, liese Schwierigkeiten zu überwinden» was erfindungsgeaäß daluroh erreicht wird, daß als Füllung ein vereohäuates Material verwendet wird, das, wenn es in die Kappe eingefüllt wird» «loh lusdehnt, umd dann eine Füllung von zellularer bzw. zellenartiger Jtruktur zu bilden.In the case of such ball-and-socket joints, it is common Practice using a resilient cap to prevent dirt and / or moisture from entering the interior of the cap yemeiden and damage to the bearing surface ron ball and Pan su prevent. The seal is particularly at Ball joint connections are necessary in which the bearing bushes, which are normally between the bearing surfaces of the ball and Pan are provided, made of plastic, as they are for example in so-called fat-free joints (joints that are not smeared off! are provided. The naohgibeigen caps consist of natural or synthetic rubber or other suitable elastomers! However, it is difficult to put a sealing cap on create that the penetration of So skin * and «ater over the entire expected service life of the connection is prevented. Ea is known to create a receptacle for dirt and water by filling the inside of the cap with grease. According to experience however, difficulties arise in attaching a cap filled with grease, and it is the object of the invention to to overcome these difficulties »what invented daluroh what is achieved is that an Vereohäuates material is used as the filling is used that when it is poured into the cap »« tan lus expands, and then a filling of cellular or cellular To form structure.

In der Zeichnung 1st ia Sehnitt ein Auführungabeiepiel einer Kugelgelenkverbindung dargestellt, wie sie z.B. in eines Pahrzeug-lenkmeohanismus Terwendet wird.In the drawing, Sehnitt is a performance example a ball-and-socket joint shown, for example, in a Vehicle steering mechanism is used.

Die in der Zeichnung dargestellte Kugel gelenkverbindung 1st allgemein von herkömmlicher Bauart und eoll demzufolge nur kurs beschrieben werden. Die Kugelgelenkverbindung weist eine Pfanne mit einem sieh in radialer Richtung erstreckenden rohrförmigen Arm 2 auf, der mit Gewinde versehen ist, um das mit einem entsprechenden Gewinde versehene Ende einer Verbindungsstange aufzunehmen. Die Bohrung der Pfanne enthält obere und untere iiagerbuohsen 3 und 4>, die mit dem Kugelende 5 der Kugelst eng· 6 der Verbindung musammenwirken. Eine flexible Kappe 7 ist vorgesehen, um das Eindringen von Feuchtigkeit und Sohmuts in das Innere der Verbindung zu verhindern.The ball joint connection shown in the drawing 1st generally of conventional design and therefore only a course to be discribed. The ball joint connection has a socket with a tubular shape extending in the radial direction Arm 2 which is threaded around the correspondingly threaded end of a connecting rod to record. The bore of the socket contains upper and lower bushes 3 and 4, which are closely connected to the end of the ball 5 of the ball piece 6 of the connection interact. A flexible cap 7 is provided to prevent moisture and sohmuts from getting inside the joint.

Erfindungegemäß wird nach dem Anbringen der Kappe an der Verbindung das Innere der Kappe mit einem verschäumten Material bzw. Schaumstoff gefüllt, welohea bzw. weloher sioh beim Einfüllen in die Kappe ausdehnt, um so eine Pullung au bilden, die mit 3 bezeichnet ist und eine zellenartige Struktur aufweist. According to the invention, after the cap has been attached to the Connect the inside of the cap with a foamed material or foam filled, welohea or weloher sioh when filling expands into the cap, so as to form a pull which is denoted by 3 and has a cell-like structure.
