Abstract
Description
Die Erfindung betrifft einen Kugelzapfen für ein Kugelgelenk gemäß der im Oberbegriff des Patentanspruches 1 angegebenen Art.The invention relates to a ball stud for a ball joint according to the specified in the preamble of claim 1. Art.
Kugelzapfen zur Verwendung in einem Kugelgelenk sind hinreichend bekannt und werden insbesondere bei Kraftfahrzeugen im Bereich von Radaufhängung oder Lenkung eingesetzt.Ball studs for use in a ball joint are well known and are used particularly in motor vehicles in the area of suspension or steering.
Ein gattungsgemäßer, sämtliche Merkmale des Oberbegriffs des Patentanspruches 1 aufweisender Kugelzapfen für ein Kugelgelenkt ist beispielsweise in der
Der Erfindung liegt die Aufgabe zugrunde, einen Kugelzapfen für ein Kugelgelenk gemäß der im Oberbegriff des Patentanspruches 1 angegebenen Art derart weiterzubilden, dass mittels des Kugelzapfens eine Einstellung des Kugelgelenks ermöglicht ist.The invention has the object of providing a ball pin for a ball joint according to the type specified in the preamble of claim 1 such that by means of the ball pin adjustment of the ball joint is possible.
Diese Aufgabe wird durch die kennzeichnenden Merkmale des Patentanspruches 1 in Verbindung mit seinen Oberbegriffsmerkmalen gelöst.This object is achieved by the characterizing features of claim 1 in conjunction with its generic features.
Die Unteransprüche bilden vorteilhafte Weiterbildungen der Erfindung.The dependent claims form advantageous developments of the invention.
In bekannter Art und Weise umfasst der Kugelzapfen für ein Kugelgelenk eine Gelenkkugel, einen Schaft sowie einen zwischen Gelenkkugel und Schaft angeordneten Übergangsbereich.In a known manner, the ball pin for a ball joint comprises a joint ball, a shaft and a transition region arranged between the joint ball and the shaft.
Erfindungsgemäß ist die Gelenkkugel um ein Exzentrizitätsmaß exzentrisch versetzt zur Symmetrielinie des Schaftes angeordnet. Durch die erfindungsgemäße exzentrische Anordnung der Gelenkkugel in Bezug zum Schaft des Kugelzapfens, ist es in vorteilhafter Weise nunmehr möglich, durch eine Drehbewegung des Kugelzapfens die Position der Gelenkkugel gegenüber dem Schaft bedarfsweise einzustellen. D. h. die Position der Gelenkkugel kann gegenüber dem Schaft bei Bedarf in radiale Richtung ”verschoben” werden um z. B. die Vorspur oder den Sturz einzustellen bzw. einen Kinematikpunkt zu optimieren oder Toleranzen zu eliminieren.According to the invention, the joint ball is arranged eccentrically offset eccentrically to the line of symmetry of the shaft. Due to the inventive eccentric arrangement of the ball joint in relation to the shank of the ball stud, it is now possible in an advantageous manner to adjust the position of the ball joint relative to the shaft as required by a rotational movement of the ball stud. Ie. the position of the joint ball can be "shifted" relative to the shaft if necessary in the radial direction to z. B. to adjust the toe or camber or to optimize a kinematic point or to eliminate tolerances.
Gemäß einer ersten Ausführungsform der Erfindung ist hierbei der Schaft des Kugelzapfens zylinderförmig ausgebildet. Die zylinderförmige Ausgestaltung des Schaftes erweist sich als vorteilhaft, da hierdurch eine vereinfachte Verstellung gewährleistet ist.According to a first embodiment of the invention, in this case, the shank of the ball stud is cylindrical. The cylindrical design of the shaft proves to be advantageous, since this ensures a simplified adjustment.
Gemäß einer anderen Ausführungsform der Erfindung weist der Schaft des Kugelzapfens einen in axiale Richtung betrachtet kegelförmig ausgebildeten Abschnitt auf. Diese Ausführungsform hat den Vorteil, dass durch den kegelförmig ausgebildeten Abschnitt eine Selbsthemmung gewährleistet ist.According to another embodiment of the invention, the shank of the ball stud has a cone-shaped section viewed in the axial direction. This embodiment has the advantage that a self-locking is ensured by the conically shaped portion.
Um eine einfache Befestigung des Kugelzapfens an einem Anbauteil eines Kraftfahrzeugs zu gewährleisten, ist vorzugsweise der Schaft des Kugelzapfens an seinem der Gelenkkugel gegenüberliegenden Endbereich mit einem Gewinde versehen.In order to ensure a simple attachment of the ball stud to an attachment of a motor vehicle, preferably the shank of the ball stud is provided with a thread at its end region opposite the joint ball.
Weitere Vorteile, Merkmale und Anwendungsmöglichkeiten der vorliegenden Erfindung ergeben sich aus der nachfolgenden Beschreibung in Verbindung mit dem in den Zeichnungen dargestellten Ausführungsbeispiel.Further advantages, features and possible applications of the present invention will become apparent from the following description in conjunction with the embodiment illustrated in the drawings.
