Description
Die Erfindung betrifft einen Gelenkkopf gemäß dem Oberbegriff des Hauptanspruchs.The invention relates to a joint head according to the preamble of the main claim.
Bei solchen Gelenkköpfen ist ee notwendig, einen Schutzbalg aufzusetzen. Um diesen dicht an dem Gelenkkopf zu lagern, ist eine nach außen offene Nut vorgesehen. Deren Anbringung macht jedoch Probleme, wenn der Gelenkkopf auf einer dicken Kolbenstange befestigt werden muß.With such rod ends it is necessary to put on a protective bellows. In order to mount this close to the joint head, an outwardly open groove is provided. However, their attachment creates problems if the joint head has to be attached to a thick piston rod.
Der Erfindung liegt die Aufgabe zugrunde, die Anbringung der Nut an einen Gelenkkopf der gattungsgemäßen Art zu vereinfachen.The invention is based on the task of attaching the groove to a joint head of the generic type simplify.
Diese Aufgabe wird bei einem gattungsgemäßen Gelenkkopf gemäß dem Oberbegriff des Hauptanspruchs erfindungsgemäß durch dessen kennzeichnende Merkmale gelöst. Somit kann unabhängig von der Dicke der Kolbenstange, an der der Gelenkkopf vorzugsweise durch Aufschrumpfen festgelegt ist, die Nut mit dem Widerlager, gegebenenfalls in der Aussparung wesentlich einfacher angebracht werden. Im Gegensatz zum Stand der Technik wird ein Schutzbalg mit einer Dichtlippe verwendet, die sich nach außen spreizt und an dem nach innen gerichteten Widerlager der Nut zur Anlage kommt,This object is achieved according to the invention with a joint head of the generic type according to the preamble of the main claim solved by its characteristic features. Thus, regardless of the thickness of the piston rod, on which the joint head is preferably fixed by shrinking on, the groove with the abutment, possibly in the recess, can be attached much more easily. In contrast the prior art uses a protective bellows with a sealing lip that spreads outward and on which inwardly directed abutment of the groove comes to rest,
Zweckmäßige Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Appropriate refinements and developments of the invention are characterized in the subclaims.

Ein AusfUhrungsbeispiel der Erfindung wird nachfolgend unter Bezugnahme auf c'ie Zeichnung näher erläutert, die einen schematischen Querschnitt durch das Ende einer Kolbenstange und des daran festgelegten Gelenkkopfes zeigt.An exemplary embodiment of the invention is explained in more detail below with reference to the drawing, which shows a schematic cross section through the end of a piston rod and the joint head attached to it.
An der insgesamt mit 1 bezeichneten Kolbenstange ist der Gelenkkopf 2 durch Aufschrumpfen festgelegt. Dieser weist eine Gelenkkugel 3 mit einem Schaft 4 auf. Konzentrisch zu der Achse des Schaftes 4 ist eine Aussparung 5 vorgesehen, in der - ebenfalls konzentrisch zu dem Schaft 4 der Gelenk· kugel 3 - eine sich zu dem Schaft 4 hin offene Nut 6 befindet. In dieser Nut 6 wird das eine als Dichtlippe 7 ausgebildete Ende eines insgesamt mit 8 bezeichneten Schutzbalges eingebracht.The joint head 2 is fixed by shrinking on the piston rod, which is designated as a whole by 1. This one shows a joint ball 3 with a shaft 4. A recess 5 is provided concentrically to the axis of the shaft 4, in which - likewise concentric to the shaft 4 of the joint ball 3 - there is a groove 6 which is open towards the shaft 4. In this groove 6, one end, designed as a sealing lip 7, of a protective bellows designated as a whole by 8 is introduced.
Die Nut 6 weist hierbei eine Erstreckung in Richtung der Achse des Schaftes 4 auf, d.h. bildet in ihrer gedachten Verlängerung eine kegelförmige Fläche, deren Spitze in der Achse des Schaftes 4 endet. Die Öffnung der Nut 6 ist von der Gelenkkugel 3 in Richtung der Achse des Schaftes 4 weg gerichtet. Schließlich weist die Nut einen von ihrer Öffnung beabstandeten Bereich als Widerlager 9 auf, der zumindest teilweise einen größeren Abstand von dem Schaft 4 als der dazwischen liegende Teil der Nut 6 besitzt.The groove 6 here has an extension in the direction of the axis of the shaft 4, i.e. forms in its imaginary Extension of a conical surface, the tip of which ends in the axis of the shaft 4. The opening of the groove 6 is directed away from the joint ball 3 in the direction of the axis of the shaft 4. After all, the groove has one of theirs Opening spaced area as an abutment 9, which is at least partially a greater distance from the shaft 4 than the intermediate part of the groove 6 has.
