Abstract
Anordnung eines als sog.

Description
Die Erfindung betrifft die Anordnung eines als sog. Traggelenk oder Radführungsgelenk fungierenden Kugelgelenks nach dem Oberbegriff des einzigen Patentanspruchs. Zum technischen Umfeld wird neben der
Derzeit üblicher Stand der Technik sind aus einem Stahlwerkstoff gefertigte Schwenklager, in die bzw. in deren entsprechend gestaltete Aufnahmeöffnung ein sog. Traggelenk (dieser Begriff wird oftmals in Verbindung mit einer Querlenker-Achse verwendet) oder Radführungsgelenk (dieser Begriff wird oftmals in Verbindung mit einer Federbein-Achse verwendet) mit seiner die Gelenkkugel aufnehmenden Tragschale eingepresst wird bzw. ist. Zusätzlich kann dabei die Tragschale in der Aufnahmeöffnung durch ein Sicherungselement, bspw. in Form eines Sicherungsringes, gesichert sein.Currently customary state of the art are manufactured from a steel material pivot bearing into or in the correspondingly shaped receiving opening a so-called. Support joint (this term is often used in conjunction with a wishbone axis) or Radführungsgelenk (this term is often used in conjunction with a Used suspension strut axis) is pressed with his the ball joint receiving support shell or is. In addition, the support shell can be secured in the receiving opening by a securing element, for example in the form of a securing ring.
In einem aus einer Leichtmetalllegierung gefertigten Schwenklager ist jedoch ein Traggelenk (mit einer notwendigerweise hochfesten, steifen Tragschale zur Aufnahme der Gelenkkugel) nicht über einen Presssitz fixierbar, weswegen hiermit eine einfache und dennoch zuverlässige und dabei geometrisch exakt festlegbare Anordnung eines Kugelgelenks in einem Leichtmetall-Schwenklager oder -Radträger eines Fzg.-Fahrwerks aufgezeigt werden soll (= Aufgabe der vorliegenden Erfindung).In a made of a light metal alloy pivot bearing, however, a ball joint (with a necessarily high-strength, rigid support shell for receiving the ball joint) can not be fixed via a press fit, so hereby a simple yet reliable and thereby geometrically exactly fixable arrangement of a ball joint in a light metal pivot bearing or wheel carrier of a vehicle chassis is to be shown (= object of the present invention).
Die Lösung dieser Aufgabe besteht für eine Anordnung nach dem Oberbegriff des Anspruchs 1 darin, dass der besagte Außenwand-Abschnitt, mit dem sich die Tragschale am Aufnahmeabschnitt der Aufnahmeöffnung abstützt, die Form einer konvexen Kugelschicht besitzt, wobei der Aufnahmeabschnitt des in Leichtmetall ausgeführten Schwenklagers oder Radträgers in Form eines konkaven Kugelschicht-Abschnittes gestaltet ist, und dass der sich in der Aufnahmeöffnung an den genannten konkaven Kugelschicht-Abschnitt des Aufnahmeabschnitts zur genannten Mutter hin anschließende Freigängigkeitsabschnitt ebenfalls im wesentlichen die Form einer konkaven Kugelschicht aufweist. Die jeweiligen Kugelschichtabschnitte sind mittels Kugelfräsern äußerst einfach darstellbar, so dass die Genauigkeitsanforderungen geringer sind als im bekannten Stand der Technik, bei welchem die miteinander zusammenwirkenden Abschnitte kegelförmig gestaltet sind.The solution of this problem is for an arrangement according to the preamble of claim 1 is that said outer wall portion, with which the support shell is supported on the receiving portion of the receiving opening, has the shape of a convex spherical layer, wherein the receiving portion of the executed in light metal pivot bearing or Wheel carrier is designed in the form of a concave spherical layer section, and that in the receiving opening at the said concave spherical layer portion of the receiving portion to said nut subsequent free-running portion also has substantially the shape of a concave spherical layer. The respective spherical layer sections are extremely easy to represent by means of ball end mills, so that the accuracy requirements are lower than in the known state of the art, in which the interacting sections are designed conical.
