Description
Kugelgelenklager Raumbewegliche Gelenke mit kugelförinigern Gelenkzapfen sind bekannt. Sie haben z. B. bereits Anwendung gefunden bei Anhängerkupplungen von Kraftfahrzeugen. Die bekannten Ausführungen genügen jedoch nicht allen Anforderungen an Betriebssicherheit, vor allem weil sich bei Verschleiß der Lagerflächen im Lager Spiel einstellt, das zu Geräuschen und Stößen führt. Es sind zwar Kugelgelenklager bekann, bei denen die den Kugelzapfen umgebenden,- am Umfange kegelig -ausgebildeten Lagerschalen sich unter dem Druck einer an der Einführungsstelle tles Kugelzapfens in einem Halter, z. B. einer Nachstellmutter, liegenden Schraubenfeder selbsttätig nachstellen. Bei Verwendung einer solchen Feder ist jedoch ein unnötig langer und daher schwerer Kugelschaft erforderlich.Ball joint bearings Spatially movable joints with spherical pivot pins are known. You have e.g. B. already found application in trailer hitches of motor vehicles. However, the known designs do not meet all requirements in terms of operational safety, especially because wear and tear of the bearing surfaces in the warehouse Adjusts play that leads to noise and bumps. It is true that they are ball-and-socket bearings known, in which those surrounding the ball stud - conical at the circumference - -shaped Bearing shells are under the pressure of a tles ball stud at the insertion point in a holder, e.g. B. an adjusting nut, lying coil spring automatically readjust. When using such a spring, however, an unnecessarily long and therefore a heavy ball shaft is required.
Erfindungsgemäß wird dieser Nachteil dadurch behoben, daß die Feder als geschlitzte Ringfeder ausgebildet und mit einer kegeligen Mantellläche versehen ist, die an der entsprechend kegelig gestalteten Wand des am Gehäuse des Gelenkes befestigten Federhalters anliegt. In der Zeichnung ist ein .-£usführunäsbeispiel des Erfindungsgegenstandes -dargestellt.. und zwar zeigt: Abb. i das Kugelgelenklager im senkrechten Schnitt bei noch nicht eingetretenem Verschleiß, Abb. 2 eine Draufsicht in Verbindung mit einem Anwendungsbeispiel und Ab .3 das Kugelgelenklager im Schnitt bei eingetretenem Verschleiß.According to the invention, this disadvantage is eliminated in that the spring designed as a slotted ring spring and provided with a conical outer surface is that on the correspondingly conical wall of the housing of the joint attached spring holder rests. The drawing shows an exemplary embodiment of the subject matter of the invention -shown .. namely shows: Fig. i the ball joint bearing in vertical section with wear not yet occurred, Fig. 2 is a top view in connection with an application example and Fig. 3 the ball joint bearing in section if wear has occurred.
Als Anwendungsbeispiel ist eine Anhängerkupplung gewählt worden. Der eine Kupplungsteil i ist deichselartig ausgebildet, an dein anderen Kupplungsteil 2 befindet sich ein kugelförmiger Kupplungszapfen 3. Die beiden Kupplungsteile 1, 2 sind durch zwei Bolzen d. miteinander verbunden. Das Kugelgelenk lager besteht aus z«-ei in einer konischen Bohrung des Kupplungsgehäuses 5 untergebrachten Lagerschalen 6, die den Kugelzapfen 3 umschließen. Die Teilungsebenen liegen quer zur Zugrichtung. Das Kupplungsgehäuse 5 ist durch eine in das Gehäuse einschraubbare Mutter 7 abgeschlossen. In dein Raum zwischen Mutter 7 und Lagerschalen 6 ist eine Feder 8 angeordnet, die als geschlitzter Ring ausgebildet ist. Die Mutter 7 übt über den Federring 8, der mit seiner konischen Mantelfläche in einer ent-,prechend gestalteten Bohrung der Mutter 7 s untergebracht ist, axialen Druck auf die Lagerschalen 6 aus, die -hierdurch radial an den Gelenkzapfen 3 angepreßt werden. Die Feder 8 ist in der Lage, sich einstellendes -Spiel bis zu einer gewissen Größe selbsttätig auszugleichen, indem sie sich entspannt. Die Feder 8 wirkt als Reibungsfeder. Der durch sie über die Lagerschalen 6 ausgeübte Preßdruck ist durch Anziehen der Mutter 7 regelbar.A trailer coupling has been chosen as an application example. Of the a coupling part i is designed like a drawbar, on your other coupling part 2 there is a spherical coupling pin 3. The two coupling parts 1, 2 are by two bolts d. connected with each other. The ball joint bearing is made from z «-ei housed in a conical bore of the clutch housing 5 bearing shells 6, which enclose the ball stud 3. The planes of division are perpendicular to the direction of pull. The coupling housing 5 is closed by a nut 7 that can be screwed into the housing. In your space between nut 7 and bearing shells 6 a spring 8 is arranged, the is designed as a slotted ring. The nut 7 exercises over the spring ring 8, the with its conical surface in a correspondingly designed bore of the Nut 7 s is housed, axial pressure on the bearing shells 6, the -through be pressed radially against the pivot pin 3. The spring 8 is able to Self-compensating for the adjusting clearance up to a certain size by she relaxes. The spring 8 acts as a friction spring. The one through them about the The pressure exerted on the bearing shells 6 can be regulated by tightening the nut 7.
