Description

Lagerschale und Kugelgelenk mit einer solchen Lagerschale Bearing shell and ball joint with such a bearing shell
Die vorliegende Erfindung bezieht sich auf eine Lagerschale gemäß dem Oberbegriff des Anspruchs 1 und ein Kugelgelenk mit einer solchen Lagerschale gemäß dem Oberbegriff des Anspruchs 10.The present invention relates to a bearing shell according to the preamble of claim 1 and a ball joint with such a bearing shell according to the preamble of claim 10.
Eine derartige Lagerschale und ein Kugelgelenk mit einer derartigen Lagerschale ist aus der WO 98/15746 bekannt. Dort wird die Kugel in die größer als die Kugel ausgebildete Aussparung des Kugelgelenkgehäuses eingesetzt und durch mechanische Mittel lagefixiert und anschließend der gebildete Freiraum durch einen Spritzvorgang mit Füllmaterial ausgefüllt. Anschließend wird der Raum oberhalb der Kugel und ein Teil des Kugelzapfens mit einer eine Abdichtung bildenden Umhüllung aus einem vernetzten und/oder unvernetzten Elastomer ausgefüllt. Hierbei muß das verwendete Formwerkzeug an die Formen des Kugelgelenkgehäuses und des Kugelzapfens angepaßt sein. Für verschiedene Kugelgelenkabmessungen oder Kugelgelenkformen müssen daher unterschiedliche spezielle Formwerkzeuge erstellt werden. Vorteilhaft an dieser vorbekannten Lösung ist, daß die getrennte Herstellung und Lagerhaltung der Manschetten bzw. Bälge und der Sicherungs- bzw. Spiralfederringe entfällt, da sich der Kunststoff der Umhüllung beim Anformen in die Nut hinein erstreckt und sich mit dem Material des Kugelgelenkgehäuses formschlüssig verbindet. Mit der vorliegenden Erfindung soll die Aufgabe gelöst werden, die Herstellung eines Kugelgelenks noch mehr zu vereinfachen und noch kostengünstiger zu gestalten.Such a bearing shell and a ball joint with such a bearing shell is known from WO 98/15746. There, the ball is inserted into the recess of the ball joint housing which is larger than the ball and is fixed in position by mechanical means, and the free space formed is then filled with filler material by an injection process. The space above the ball and part of the ball pin are then filled with a covering which forms a seal and is made of a crosslinked and / or uncrosslinked elastomer. Here, the mold used must be adapted to the shapes of the ball joint housing and the ball pin. Different special molding tools must therefore be created for different ball joint dimensions or ball joint shapes. The advantage of this known solution is that the separate manufacture and storage of the sleeves or bellows and the locking or spiral spring washers is eliminated, since the plastic of the casing extends into the groove when it is formed and connects to the material of the ball joint housing in a form-fitting manner. The object of the present invention is to simplify the production of a ball joint even more and to make it even more cost-effective.
Dies soll insbesondere dadurch ermöglicht werden, daß der Verbund zwischen der Lagerschale und der Abdichtmanschette in möglichst einem Formwerkzeug herstellbar ist.This is to be made possible in particular by the fact that the bond between the bearing shell and the sealing sleeve can be produced in one possible mold.
Gelöst wird das Problem des Verbundes zwischen der Lagerschale und der Abdichtmanschette durch die Merkmale des Anspruchs 1 und die einfache Herstellung des Kugelgelenks durch die Merkmale des Anspruchs 10.The problem of the bond between the bearing shell and the sealing sleeve is solved by the features of claim 1 and the simple manufacture of the ball joint by the features of claim 10.
Die Herstellung des Verbundes zwischen der Lagerschale und der Abdichtmanschette wird durch das an sich bekannte 2K- Verfahren erreicht. Hierbei werden zwei Kunststoffe unterschiedlicher Art in einem Formwerkzeug nacheinander gespritzt und die aus den beiden Kunststoffen gespritzten Teile zugleich stoff- und/oder formschlüssig miteinander verbunden. Dieses Verbundteil kann durch die erfindungsgemäße Aufteilung der Lagerschale in einzelne Lagerschalensegmente am Pol aufgespreizt werden, so daß der Kugelzapfen eingeführt und die Kugel in die Lagerschale eingeschnappt werden kann. Zugleich legt sich hierbei die Abdichtmanschette an den Kugelzapfen dichtend an. Diese zusammengesetzte Einheit kann zur Ausbildung verschiedenartiger Kugelgelenke mit beispielsweise unterschiedlichen Kugelgelenkgehäusen oder dgl. verwendet werden.The connection between the bearing shell and the sealing sleeve is produced by the 2K process known per se. In this case, two plastics of different types are injected one after the other in a mold and the parts molded from the two plastics are simultaneously connected to one another in a material and / or form-fitting manner. This composite part can be spread by the inventive division of the bearing shell into individual bearing shell segments at the pole, so that the ball pin can be inserted and the ball can be snapped into the bearing shell. At the same time, the sealing sleeve seals against the ball stud. This composite unit can be used to form different types of ball joints with, for example, different ball joint housings or the like.
Weitere vorteilhafte Einzelheiten der Erfindung sind in den Unteransprüchen angegeben und werden nachfolgend anhand der in der Zeichnung veranschaulichten Ausführungsbeispiele näher beschrieben. Es zeigen:Further advantageous details of the invention are specified in the subclaims and are described below with reference to the exemplary embodiments illustrated in the drawing described in more detail. Show it:

In den Fig. 1 und 2 sind mit 1 ein Kugelgelenk mit einem Kugelgelenkgehäuse 2 bezeichnet. In einer Aussparung 3 des Kugelgelenkgehäuses 2 ist im Abstand zu deren Innenwand 3.1 eine auf eine Kugel 4 aufgeschnappte Lagerschale 5 vorgesehen. An den dem Kugelzapfen 6 zugewandten Rand 5.1 der Lagerschale 5 ist eine Abdichtmanschette 7 durch einen Spritz- oder Preßprozeß stoff- und/oder formschlüssig angeformt. Die Lagerschale 5 besteht aus einem gute Gleiteigenschaften aufweisenden, spritz- und/oder preßbarem Material, vorzugsweise aus Polyoximethylen (POM) .1 and 2, 1 denotes a ball joint with a ball joint housing 2. A bearing shell 5 snapped onto a ball 4 is provided in a recess 3 of the ball joint housing 2 at a distance from its inner wall 3.1. On the edge 5.1 of the bearing shell 5 facing the ball stud 6, a sealing sleeve 7 is integrally and / or positively formed by an injection or pressing process. The bearing shell 5 consists of a sprayable and / or pressable material which has good sliding properties, preferably of polyoxymethylene (POM).
Erfindungsgemäß ist die Lagerschale 5 durch einen oder mehrere Schlitze 8, welche vom oberen Rand 5.1 aus bis zum Pol 5.2 der Lagerschale 5 reicht bzw. reichen in wenigstens zwei vollkommen voneinander getrennte Lagerschalensegmente 5.3 unterteilt. Die einzelnen benachbarten Lagerschalensegmente 5.3 sind am Rand 5.1 lediglich durch die angeformte, insbesondere angespritzte Abdichtmanschette 7 aus einem elastischen Material, wie aus einem thermoplastischen Elastomer (TPE) miteinander verbunden. Insbesondere kann ein lineares Polyurethan-Elastomer (TPU) eingesetzt werden. Hierdurch sind die Lagerschalensegmente 5.1 vom Pol 5.2 aus nach außen abspreizbar. Demgemäß kann bei abgespreizten Lagerschalensegmenten 5.3 der Kugelzapfen 6 durch den offenen Pol 5.2 in die Abdichtmanschette 7 eingeschoben werden, bis die Kugel 4 bei sich schließenden Lagerschalensegmenten 5.3 in die Lagerschale 5 einschnappt. Diese Einheit aus Kugel 4 mit Kugelzapfen 6 und Abdichtmanschette 7 mit Lagerschale 5 wird in die Aussparung 3 eines Kugelgelenkgehäuses 2 eingesetzt und durch Einbringen von Füllmaterial 9 in den Freiraum 3.2 zwischen Lagerschale 5 und Innenwand 3.1 im Kugelgelenkgehäuse 2 fest verankert. Als Füllmaterial dient ein fester Kunststoff, insbesondere aus oder auf der Basis eines Thermoplasts oder Duroplasts. Bevorzugt kann das Füllmaterial 9 in an sich bekannter Weise mit Stoffen versetzt sein, die die Festigkeit des Füllmaterials erhöhen.According to the invention, the bearing shell 5 is divided by one or more slots 8, which extends from the upper edge 5.1 to the pole 5.2 of the bearing shell 5 or extend into at least two bearing shell segments 5.3 that are completely separate from one another. The individual adjacent bearing shell segments 5.3 are connected to one another at the edge 5.1 only by the molded-on, in particular injection-molded sealing sleeve 7 made of an elastic material, such as a thermoplastic elastomer (TPE). In particular, a linear polyurethane elastomer (TPU) can be used. As a result, the bearing shell segments 5.1 can be spread outward from the pole 5.2. Accordingly, when the bearing shell segments 5.3 are spread apart, the ball pin 6 can be inserted through the open pole 5.2 into the sealing collar 7 until the ball 4 snaps into the bearing shell 5 when the bearing shell segments 5.3 close. This unit of ball 4 with ball pin 6 and sealing sleeve 7 with bearing shell 5 is inserted into the recess 3 of a ball joint housing 2 and is firmly anchored in the ball joint housing 2 by introducing filler material 9 into the space 3.2 between the bearing shell 5 and the inner wall 3.1. A solid plastic is used as the filling material, in particular made of or based on a thermoplastic or thermoset. The filling material 9 can preferably be mixed in a manner known per se with substances which increase the strength of the filling material.
Um das Einbringen des Füllmaterials 9, insbesondere durch einen Spritzprozeß am Pol 5.2 günstig vornehmen zu können, ist an einem Lagerschalensegment 5.3 eine Polkappe 5.4 angeformt, die einen Bereich des Pols 5.2 abdeckt. Entsprechend sind die übrigen Lagerschalensegmente 5.3 im Bereich der Polkappe 5.4 derart verkürzt, daß sie, bis auf den Verbleib eines geringen Spaltes 10, bis an die Polkappe 5.2 heranreichen. Beim Einspritzen des Füllmaterials trifft dieses auf die Polkappe 5.2 und verteilt sich dadurch besser. Außerdem wird verhindert, daß durch den Spritzdruck ein Lagerschalensegment 5.3 sich von der Kugeloberfläche abheben kann und Füllmaterial 9 zwischen Kugel 4 und Lagerschale 5 eindringt. Zum einfachen Einsetzen und Zentrieren und gegebenenfalls auch zum Fixieren der Lagerschale 5 in der Aussparung 3 sind an deren Außenfläche 5.5 am Umfang verteilt mehrere seitlich abstehende Nasen 5.6 angeformt. Vorzugsweise befinden sich diese Nasen 5.6 im Bereich des Äquators 11 der Lagerschale 5 bzw. der Kugel 4. Diese Nasen 5.6 zentrieren die Lagerschale 5 beim Einsetzen in die Aussparung 3. Sie können an der Innenwand 3.1 lose oder insbesondere unter Vorspannung anliegen und so die genannte Einheit in der Aussparung 3 festhalten. Hierdurch wird der Formvorgang zum Einfüllen des Füllmaterials 9 erleichtert, da keine besonderen Halte- und Fixiermittel benötigt werden. Vorteilhaft können die Nasen 5.6 ausschließlich oder zusätzlich am Rand 8.1 eines Schlitzes 8 vorgesehen sein, wie in der Zeichnung in Fig. 3 dargestellt. In Fig. 3 ist mit 12 die Schnittlinie der Schnittebene I-I der Fig. 1 eingezeichnet.In order to be able to introduce the filling material 9 cheaply, in particular by a spraying process on the pole 5.2, a pole cap 5.4 is formed on a bearing shell segment 5.3, which covers a region of the pole 5.2. Correspondingly, the remaining bearing shell segments 5.3 in the area of the pole cap 5.4 are shortened in such a way that, except for the fact that a small gap 10 remains, they reach as far as the pole cap 5.2. When the filling material is injected, it hits the polar cap 5.2 and is thus better distributed. In addition, it is prevented by the injection pressure that a bearing shell segment 5.3 can stand out from the ball surface and filler material 9 penetrates between the ball 4 and the bearing shell 5. For easy insertion and centering and, if necessary, also for fixing the bearing shell 5 in the recess 3, a plurality of laterally projecting lugs 5.6 are formed on the outer surface 5.5 distributed over the circumference. These lugs 5.6 are preferably located in the area of the equator 11 of the bearing shell 5 or the ball 4. These lugs 5.6 center the bearing shell 5 when they are inserted into the recess 3. They can rest loosely on the inner wall 3.1, or in particular under tension, and so on Hold the unit in the recess 3. This simplifies the molding process for filling the filling material 9, since no special holding and fixing means are required. Advantageously, the lugs 5.6 can be provided exclusively or additionally on the edge 8.1 of a slot 8, as shown in the drawing in FIG. 3. In Fig. 3, the section line of section plane II of Fig. 1 is shown at 12.
Mit Vorteil steht der Rand 5.1 der Lagerschale 5 ganz oder wenigstens abschnittsweise über den Außendurchmesser 7.1 der Abdichtmanschette 7 über. Hierdurch kann dieser beim Einsetzen in die Aussparung 3 an einem Anschlag 3.3 derselben anliegen und sowohl die Einsetztiefe begrenzen als auch die Fixierung begünstigen.Advantageously, the edge 5.1 of the bearing shell 5 projects completely or at least in sections beyond the outer diameter 7.1 of the sealing collar 7. As a result, the latter can rest against a stop 3.3 when inserted into the recess 3 and both limit the insertion depth and promote fixation.
Vorteilhaft besitzt das Kugelgelenkgehäuse 2 einen über den Pol 5.2 der Lagerschale 5 überstehenden Wandteil 2.1. Dieser Wandteil 2.1 wird nach dem Einsetzen der Einheit aus Kugel 4 mit Kugelzapfen 6 und Lagerschale 5 mit Abdichtmanschette 7 nach innen umgebördelt und dann der Freiraum 3.2 mit dem Füllmaterial 9 ausgefüllt. The ball joint housing 2 advantageously has a wall part 2.1 projecting beyond the pole 5.2 of the bearing shell 5. This wall part 2.1 is flanged inwards after inserting the unit consisting of ball 4 with ball stud 6 and bearing shell 5 with sealing collar 7 and then the free space 3.2 is filled with the filling material 9.
