Description

Die Erfindung bezieht sich auf ein Kugelgelenk, insbesondere für Lenk- und Steuergestänge von Kraftfahrzeugen, bei dem der Kugelkopf eines Gelenkzapfens in einem schalenförmigen Einsatzkörper aus Stahl oder einem für Lagerzwecke geeigneten Kunststoff im Gelenkgehäuse ruht, das an seiner dem Kugelkopf zugekehrten Seite durch einen Deckel geschlossen ist, zwischen dem und einer am Kugelkopf anliegenden Stützschale eine Schraubenfeder vorgesehen ist, der ein weiteres Federungsmittel in Form eines elastischen Zwischenstückes aus Gummi oder gummiähnlichem Kunststoff zugeschaltet ist.The invention relates to a ball joint, in particular for steering and control linkages of motor vehicles, in which the ball head of a pivot pin rests in a shell-shaped insert body made of steel or a plastic suitable for storage purposes in the joint housing, which is closed by a cover on its side facing the ball head is, between which and a support shell resting on the ball head, a helical spring is provided, to which a further spring means in the form of an elastic intermediate piece made of rubber or rubber-like plastic is connected.

Bei bekannten Kugelgelenken der eingangs beschriebenen Art ist als zusätzliches Federungsmittel ein elastisches Formstück zwischen dem Kugelkopf und der Stützschale für eine sich am entgegengesetzten Ende gegen den Verschlussdeckel des Gelenkgehäuses abstützenden Schraubenfeder vorgesehen. Mit dem elastischen Zwischenstück soll ein zwischen einem Kugelkopf mit einer zu einem Kugelabschnitt verringerten Endfläche verbleibender Abstand zur Stützschale überbrückt und so dem Gelenk eine höhere Elastizität verliehen werden. Diese Ausbildung ist insofern nachteilig, als sich ein möglicherweise schon fertigungsbedingtes oder ein sich nach geraumer Betriebsdauer durch Verschleiß einstellendes Spiel zwischen den Gelenkteilen nicht völlig ausgleichen läßt.In known ball joints of the type described above, an elastic fitting is provided as additional spring means between the ball head and the support shell for a helical spring supported at the opposite end against the closure cover of the joint housing. The purpose of the elastic intermediate piece is to bridge a distance to the support shell that remains between a spherical head with an end surface that is reduced to a spherical section and thus to give the joint a higher elasticity. This design is disadvantageous insofar as it is not possible to completely compensate for play between the joint parts, which may already be due to production or which is due to wear after a long period of operation.

Dieser Zustand wird noch gefördert, wenn aus fertigungstechnischen und kostenabhängigen Gründen eine erhebliche Einengung von Bearbeitungstoleranzen erschwert ist.This state is still promoted when a considerable narrowing of machining tolerances is difficult due to manufacturing and cost-related reasons.

Ein weiterer Nachteil ergibt sich daraus, daß bei hohen und schlagartig auftretenden Gelenkbelastungen die Kraft der Schraubenfeder überbrückt wird, so daß zwischen der Stützschale und dem Verschlussdeckel ein Kontakt entstehen kann, wodurch dann unerwünschte Klappergeräusche hervorgerufen werden.Another disadvantage arises from the fact that the force of the helical spring is bridged in the event of high and sudden joint loads, so that contact can arise between the support shell and the closure cover, which then causes undesirable rattling noises.

Es ist die Aufgabe der Erfindung, solche Nachteile zu vermeiden. Insbesondere soll das schädliche Spiel zwischen den Gelenkteilen vermieden werden und deren selbsttätige Nachstellung bei eintretendem Verschleiß gewährleistet sein.It is the object of the invention to avoid such disadvantages. In particular, the damaging play between the joint parts should be avoided and their automatic readjustment should be ensured in the event of wear.

Demgemäß besteht die Erfindung darin, daß das zusätzliche Federungsmittel zwischen der Stützschale und dem Verschlussdeckel angeordnet ist.Accordingly, the invention consists in that the additional spring means is arranged between the support shell and the closure cover.

Eine bevorzugte Ausgestaltung der Erfindung liegt in der Ausbildung des zusätzlichen Federungsmittels als Profilstück mit einem die Stützschale völlig überdeckenden äußeren Randbereich, wodurch eine Berührung zwischen der Stützschale und dem Verschlussdeckel unter allen auftretenden Kräften und Stößen mit Sicherheit ausgeschlossen wird.A preferred embodiment of the invention is the formation of the additional suspension means as a profile piece with an outer edge area completely covering the support shell, whereby a contact between the support shell and the closure cover under all occurring forces and impacts is excluded with certainty.

Nach einem weiteren Merkmal der Erfindung ist das Profilstück mit einem angeformten Zapfen versehen, der in eine zentrale Öffnung des eingewölbten Bodens der Stützschale eingeklemmt ist, so daß das Profilstück lagesicher gehalten ist.According to a further feature of the invention, the profile piece is provided with an integrally formed pin which is clamped into a central opening in the arched bottom of the support shell, so that the profile piece is held in a secure manner.

Die Erfindung ist in der Zeichnung in einer Ausführungsform im Querschnitt dargestellt.The invention is shown in the drawing in one embodiment in cross section.

In der Fig. ist das Gelenkgehäuse mit 1 bezeichnet, in dem ein Gelenkzapfen 2 mit seinem Kugelkopf 3 in einer Schale 4 aus Stahl gelagert ist. Der Kugelkopf steht unter der Wirkung einer Schraubenfeder 5, die einerseits auf einer dem Kugelkopf angepassten Stützschale 6 aus Stahlblech einwirkt und sich andererseits gegen den Verschlussdeckel 7 abstützt. Zwischen diesem und der Stützschale 6 ist ein weiteres Federungselement 8 eingefügt, daß aus einem Profilstück aus einem geeigneten elastischen Kunststoff besteht und mit einem zapfenartigen Fuß 8 versehen ist, der in eine mittlere Öffnung 6 der Stützschale 6 eingreift und hierin über eine Ringnut eingeklemmt ist. Der Boden 6 der Stützschale ist eingewölbt. In dieser Vertiefung ist das Profilstück 8 lagesicher eingebettet. Der die Schraubenfeder 5 unter Spannung haltende Verschlussdeckel 7 ist in üblicher Weise durch den eingebördelten oberen Rand des Gelenkgehäuses festgelegt.In the figure, the joint housing is denoted by 1, in which a joint pin 2 with its spherical head 3 in a shell 4 is mounted from steel. The ball head is under the action of a helical spring 5, which on the one hand acts on a support shell 6 made of sheet steel and which is adapted to the ball head and on the other hand is supported against the closure cover 7. Between this and the support shell 6 another spring element 8 is inserted, which consists of a profile piece made of a suitable elastic plastic and is provided with a pin-like foot 8 which engages in a central opening 6 of the support shell 6 and is clamped therein via an annular groove. The bottom 6 of the support shell is arched. In this recess, the profile piece 8 is embedded securely in position. The closure cover 7 holding the helical spring 5 under tension is fixed in the usual way by the crimped upper edge of the joint housing.
