  Druckring für Kugelgelenke, insbesondere für Lenkgestänge von Kraftfahrzeugen 
Die Erfindung betrifft einen Druckring aus elastischem Material für aus einem Gelenkgehäuse und einem in diesem gelagerten Kugelkopf mit Kugelzapfen bestehende Kugelgelenke, insbesondere für Lenkgestänge von Kraftfahrzeugen, wobei der Druckring zwischen einem Gehäusedeckel, dem Gelenkgehäuse und den Kugelkopf umgebenden Lagerschalen angelegt ist. 



   Es ist bekannt, zwischen dem durch einen Sicherungsring gehaltenen Gehäusedeckel, dem Gelenkgehäuse und den Kugelkopf umgebenden Lagerschalen einen federnden Druckring anzuordnen. Dieser Druckring besteht in der Regel aus einem elastischen Werkstoff, während die den Kugelkopf umgebenden Lagerschalen zweckmässig aus einem starren Kunststoff, beispielsweise Polyamid, Azetalharz oder Nylon, hergestellt sind. 



   Der Erfindung liegt die Aufgabe zugrunde, einen Druckring für Kugelgelenke zu schaffen, der einerseits das Austreten des Schmiermittels aus dem Gelenkgehäuse und anderseits das Eindringen von Schmutz oder Staub in das Gelenkgehäuse vermeidet. Ausgehend von den bekannten Kugelgelenken wird die der Erfindung zugrunde liegende Aufgabe dadurch gelöst, dass der Druckring auf seinen dem Gelenkgehäuse und dem Gehäusedeckel zugekehrten Flächen mindestens eine umlaufende Dichtungslippe besitzt. Durch diese Formgebung des   Druckringes   wird eine labyrinthartige Abdichtung des Gelenkgehäuses und damit eine Verlängerung der Lebensdauer des gesamten Kugelgelenkes erzielt.

 einer weiteren   Dichtungslippe --14-- gebildet   wird.

   Durch den Wechsel der Dichtungslippen   - -11, 12, 14--   mit den Ringnuten-10, 13- wird eine labyrinthartige Abdichtung des   Gelenkgehäuses--l--erzielt.

  Pressure ring for ball joints, in particular for steering linkages of motor vehicles
The invention relates to a pressure ring made of elastic material for ball joints consisting of a joint housing and a ball head with ball studs mounted therein, in particular for steering linkages of motor vehicles, the pressure ring being placed between a housing cover, the joint housing and bearing shells surrounding the ball head.



   It is known to arrange a resilient pressure ring between the housing cover held by a locking ring, the joint housing and the bearing shells surrounding the ball head. This pressure ring usually consists of an elastic material, while the bearing shells surrounding the ball head are expediently made of a rigid plastic, for example polyamide, acetal resin or nylon.



   The invention is based on the object of creating a pressure ring for ball joints which on the one hand prevents the lubricant from escaping from the joint housing and on the other hand prevents dirt or dust from entering the joint housing. Based on the known ball joints, the object on which the invention is based is achieved in that the pressure ring has at least one circumferential sealing lip on its surfaces facing the joint housing and the housing cover. This shape of the pressure ring achieves a labyrinthine seal of the joint housing and thus an extension of the service life of the entire ball joint.

 another sealing lip --14-- is formed.

   By changing the sealing lips - -11, 12, 14 - with the annular grooves-10, 13-, a labyrinth-like seal of the joint housing - l - is achieved.
