Abstract
Description
Die Erfindung betrifft ein Kugelgelenk gemäß den Merkmalen im Oberbegriff des Anspruchs 1.The The invention relates to a ball joint according to the features in the preamble of claim 1.
Kugelgelenke werden insbesondere in den Fahrwerken von Kraftfahrzeugen dazu eingesetzt, um die Fahrzeugkinematikpunkte präzise zu definieren. Die Anforderungen an die einzelnen Bauteile der Kugelgelenke verlangen, dass bei Bewegungen der Fahrwerke möglichst keine Gegenmomente entstehen. Dazu wird die Güte der Kugelgelenke über die Prüfung der Torsionsmomente definiert. Hinzu kommt, dass die diesbezüglich dimensionierte Funktion über die Laufzeit des Kraftfahrzeugs bestehen bleibt.ball joints are used in particular in the chassis of motor vehicles to to precisely define the vehicle kinematics points. The Require requirements for the individual components of the ball joints, that when movements of the chassis as possible no counter-moments arise. This is the quality of the ball joints over defines the test of torsional moments. Come in addition, that the dimensioned function over the term of the motor vehicle remains.
Bei den bislang bekannten Kugelgelenken werden die Torsionsmomente über eine Presspassung zwischen den Lageraufnahmen, den Kugelpfannen und den Kugelköpfen bestimmt. Hierzu müssen diese drei Bauelemente in einer sehr genauen geometrischen Konstellation zueinander angeordnet sein. Zwecks Reduktion der Bandbreite der Torsionsmomente sind jedoch in der Regel zusätzliche Prozessschritte notwendig, die nach oder während der Montage der Kugelgelenke durchgeführt werden müssen.at The previously known ball joints, the torsional moments over a press fit between the bearing mounts, the ball sockets and the ball heads. For this must this Three components in a very precise geometric constellation be arranged to each other. In order to reduce the bandwidth of However, torsional moments are usually additional process steps necessary after or during assembly of the ball joints must be performed.
Um
die bei der Fertigung der Kugelgelenke nicht zu vermeidenden Herstellungstoleranzen
auszugleichen, ist im Umfang der
Der Erfindung liegt – ausgehend vom Stand der Technik – die Aufgabe zugrunde, ein Kugelgelenk zu schaffen, das bei längerer Lebensdauer über die Produktlaufzeit geringe Torsionsmomente aufweist, einfacher gefertigt und montiert werden kann, und zudem Schwingungen und Geräusche isolieren kann.Of the Invention is - starting from the prior art - the The task is to create a ball joint that lasts longer Lifespan over the product runtime low torsional moments has, is easier to manufacture and install, and moreover Isolate vibrations and noises.
Die Lösung dieser Aufgabe besteht nach der Erfindung in den Merkmalen des Anspruchs 1.The Solution to this problem consists according to the invention in the Features of claim 1.
Danach besteht die Zwischenschicht aus einem elastischen Material, das mit Vorspannung in den Spalt zwischen der Kugelpfanne und der Lageraufnahme eingebracht wird. Aufgrund der Elastizität der unter Vorspannung eingebrachten Zwischenschicht kann bei vereinfachter Montage zunächst ein einwandfreier Toleranzausgleich bei Geräuschisolierung/Entkoppelung geschaffen werden. Es wird eine höhere Lebensdauer durch eine homogene Druckverteilung erreicht. Ferner erfolgt eine Kostenreduktion, da gängige Passungstoleranzen angewendet werden können. Die Vorspannung der elastischen Zwischenschicht wird durch die Überdeckung ihrer Kontur mit der Kontur der Lageraufnahme erreicht.After that the intermediate layer consists of an elastic material, the with preload in the gap between the ball socket and the bearing receptacle is introduced. Due to the elasticity of the under bias introduced intermediate layer can at first simplified installation a perfect tolerance compensation for noise isolation / decoupling be created. It is going through a longer life achieved a homogeneous pressure distribution. Furthermore, there is a cost reduction, as common fit tolerances can be applied. The bias of the elastic intermediate layer is due to the overlap reached its contour with the contour of the bearing support.
Entsprechend den Merkmalen des Anspruchs 2 kann die Zwischenschicht aus einem Elastomer bestehen.Corresponding the features of claim 2, the intermediate layer of a Elastomer consist.
Insbesondere kann es sich nach Anspruch 3 um ein thermoplastisches Elastomer handeln.Especially it may be according to claim 3 to a thermoplastic elastomer act.
Gemäß den Merkmalen des Anspruchs 4 ist es aber auch denkbar, dass die Zwischenschicht aus Gummi besteht.According to the Characteristics of claim 4, but it is also conceivable that the intermediate layer made of rubber.
Ferner kann entsprechend Anspruch 5 die Zwischenschicht aus Polyurethan gebildet sein.Further may according to claim 5, the intermediate layer of polyurethane be formed.
Nach den Merkmalen des Anspruchs 6 besteht eine Ausführungsform darin, dass die Zwischenschicht direkt an die Kugelpfanne gespritzt ist. Dies erfolgt vor dem Zusammenbau des Kugelgelenks. Die Vorspannung der elastischen Zwischenschicht wird dann bei der Montage des Kugelgelenks vorgenommen.To The features of claim 6 is an embodiment in that the intermediate layer is injected directly onto the ball socket is. This is done before assembling the ball joint. The bias the elastic intermediate layer is then made during assembly of the ball joint.
Denkbar ist es aber auch, dass nach Anspruch 7 die Zwischenschicht als separates Bauteil gefertigt wird, welches im Zuge der Montage des Kugelgelenks in den Spalt zwischen der Kugelpfanne und der Lageraufnahme eingesetzt und anschließend vorgespannt wird.Conceivable but it is also that according to claim 7, the intermediate layer as a separate Component is manufactured, which in the course of assembly of the ball joint inserted into the gap between the ball socket and the bearing seat and then biased.
Gemäß den Merkmalen des Anspruchs 8 ist die Zwischenschicht mittels eines sich an der Lageraufnahme abstützenden und einen Radialbund sowie Federzungen an der Kugelpfanne kontaktierenden Schließdeckels unter Vorspannung gestellt.According to the Features of claim 8, the intermediate layer by means of a supported on the bearing support and a radial collar and spring tongues on the ball socket contacting closure cover put under tension.
Der Spalt zwischen der Kugelpfanne und der Lageraufnahme ist nach den Merkmalen des Anspruchs 9 aus einem zylindrischen Abschnitt und einem kugelabschnittsförmigen Abschnitt gebildet.Of the Gap between the ball socket and the bearing receiver is after the Features of claim 9 from a cylindrical portion and formed a spherical segment-shaped section.
Die Erfindung ist nachfolgend anhand eines in der Zeichnung veranschaulichten Ausführungsbeispiels näher erläutert.The Invention is illustrated below with reference to an illustrated in the drawing Embodiment explained in more detail.
