Description

Laσerschale, insbesondere für ein Kugelgelenk und Kugelgelenk mit einer solchen Lagerschale Laσerschale, especially for a ball joint 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 4.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 4.
Bei derartigen Kugelgelenken bestehen die Lagerschalen aus hartem, verschleißfestem Kunststoff mit geringem Reibungskoeffizienten. Die bei diesen Kugelgelenken vorhandenen Manschetten bestehen aus einem Elastomer, beispielsweise aus einem unter der Handelsbezeichnung Neopren bekannten Elastomer.In such ball joints, the bearing shells are made of hard, wear-resistant plastic with a low coefficient of friction. The cuffs present in these ball joints are made of an elastomer, for example of an elastomer known under the trade name neoprene.
Derartige Lagerschalen und Manschetten müssen getrennt hergestellt und in Lagern bereitgestellt und sie müssen auch gesondert montiert werden. Hierdurch entstehen relativ hohe Lager- und Montagekosten.Bearing shells and sleeves of this type must be manufactured separately and made available in bearings, and they must also be assembled separately. This results in relatively high storage and assembly costs.
Mit der vorliegenden Erfindung soll die Aufgabe gelöst werden, die Herstellungskosten für derartige Kugelgelenke zu senken.The object of the present invention is to reduce the manufacturing costs for such ball joints.
Gelöst wird diese Aufgabe durch die Merkmale der Ansprüche 1 und 4. Bei Anwendung der Erfindung wird eine gesonderte Lagerhaltung von Lagerschalen und Manschetten vermieden, da die Lagerschale mit Manschette in einer einzigen Form einer Spritzgießmaschine oder dgl. als einheitliches Bauteil hergestellt werden kann.This object is achieved by the features of claims 1 and 4. When using the invention, separate storage of bearing shells and sleeves is avoided, since the bearing shell with sleeve can be manufactured in a single mold of an injection molding machine or the like as a single component.
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 in more detail below with reference to the exemplary embodiments illustrated in the drawing. Show it:
Fig. 1 eine Lagerschale mit angeformter Manschette von der Seite, teilweise im Schnitt undFig. 1 is a bearing shell with a molded sleeve from the side, partly in section and
Fig. 2 ein Kugelgelenk mit einer Lagerschale mit angeformter Manschette von der Seite, teilweise im Schnitt.Fig. 2 shows a ball joint with a bearing shell with a molded sleeve from the side, partly in section.
In Fig. 1 ist mit 1 eine Lagerschale bezeichnet, die insbesondere zwischen einem Kugelhohlraum eines Kugelgelenkgehäuses und der Kugel eines Kugelgelenks vorgesehen ist. Kugelgelenke werden in der Regel mittels einer zwischen einem die Kugel tragenden Kugelzapfen und dem Kugelgelenkgehäuse vorgesehenen Manschette abgedichtet.In Fig. 1, 1 denotes a bearing shell, which is provided in particular between a ball cavity of a ball joint housing and the ball of a ball joint. Ball joints are usually sealed by means of a sleeve provided between a ball pin that carries the ball and the ball joint housing.
Erfindungsgemäß ist die Lagerschale 1 mit einer derartigen Manschette 2 aus einem Elastomer versehen, wobei diese Manschette 2 an der Lagerschale 1 fest und dicht angeformt ist. Die Anfor ung erfolgt beispielsweise durch Angießen oder Anspritzen in Gieß- oder Spritzgießmaschinen oder dgl.. Es liegt somit eine stoffschlüssige Verbindung zwischen Lagerschale 1 und Manschette 2 vor. Die Lagerschale 1 besteht aus einem verschleißarmen Kunststoff mit geringem Reibungskoeffizienten. Hierzu zählen insbesondere Kunststoffe aus oder auf der Basis von Polyethylen, Polypropylen, Polyoxymethylen, Polyether- sulfon, Polyetheretherketon oder Polyamid.According to the invention, the bearing shell 1 is provided with such a sleeve 2 made of an elastomer, this sleeve 2 being firmly and tightly molded onto the bearing shell 1. The request is made, for example, by casting on or injection molding in casting or injection molding machines or the like. There is thus a material connection between the bearing shell 1 and the sleeve 2. The bearing shell 1 consists of a low-wear plastic with a low coefficient of friction. These include in particular plastics made from or based on polyethylene, polypropylene, polyoxymethylene, polyether sulfone, polyether ether ketone or polyamide.
Die angeformte Manschette 2 besteht aus einem Elastomer aus oder auf der Basis von beispielsweise wenigstens einem Nitrilkautschuk, bekannt unter der Handelsbezeichnung Neopren. Dieser Nitrilkautschuk verbindet sich beim Anformen bei den hierfür notwendigen und bekannten Temperaturen und Drücken innig mit dem Material der Lagerschale 1.The molded sleeve 2 consists of an elastomer made of or based on, for example, at least one nitrile rubber, known under the trade name neoprene. This nitrile rubber binds intimately to the material of the bearing shell 1 during molding at the known and necessary temperatures and pressures.
Bevorzugt ist die Manschette 2 am Rand 3 der Kugelöffnung 4 der Lagerschale 1 angeformt. Insbesondere kann der Rand 3 seitlich nach außen geformt sein und einen Flansch 5 bilden, an dem die Manschette 2 oben angeformt ist. Vorteilhaft kann sich der Flansch 5 auf einer Stützfläche eines Kugelgehäuses abstützen, wie nachfolgend anhand der Fig. 2 beispielhaft dargestellt und beschrieben ist.The sleeve 2 is preferably formed on the edge 3 of the ball opening 4 of the bearing shell 1. In particular, the edge 3 can be shaped laterally outwards and form a flange 5, on which the sleeve 2 is molded on at the top. The flange 5 can advantageously be supported on a support surface of a ball housing, as is illustrated and described below by way of example with reference to FIG. 2.
Das Ausführungsbeispiel gemäß Fig. 2 zeigt ein Kugelgelenk mit einem Kugelgelenkgehäuse 6, das einen Kugelhohlraum 7, eine obere Einsetzöffnung 8 und zumindest eine, beispielsweise auf der Einsetzöffnung 8 gegenüberliegenden Seite 9, angebrachte Einspritzöffnung 10 besitzt.The exemplary embodiment according to FIG. 2 shows a ball joint with a ball joint housing 6, which has a ball cavity 7, an upper insertion opening 8 and at least one injection opening 10, for example on the side 9 opposite the insertion opening 8.
In den Kugelhohlraum 7 ist eine an einem Kugelzapfen 11 angeformte Kugel als Gelenkkugel 12 mit einer auf diese Gelenkkugel 12 aufgeschnappten Lagerschale 1 durch die entsprechend groß ausgebildete Einsetzöffnung 8 eingesetzt. Die Gelenkkugel 12 wird möglichst zentrisch im Kugelhohlraum 7 fixiert und dann mit einer Zwischenschicht 13 aus einem polymerisierenden Kunststoff, beispielsweise einem Thermoplast, hinterspritzt. Der Einspritzvorgang erfolgt durch die Einspritzöffnung 10. Anstelle oder zusätzlich zu dieser Einspritzöffnung 10 können auch an anderen Stellen des Kugelgelenkgehäuses 6 eine oder mehrere Einspritzöffnungen vorgesehen sein.A ball formed on a ball pin 11 is inserted into the ball cavity 7 as a joint ball 12 with a bearing shell 1 snapped onto this joint ball 12 through the correspondingly large insertion opening 8. The joint ball 12 is fixed as centrally as possible in the ball cavity 7 and then back-injected with an intermediate layer 13 made of a polymerizing plastic, for example a thermoplastic. The injection process takes place through the injection opening 10. Instead of or in addition to this injection opening 10, one or more injection openings can also be provided at other points of the ball joint housing 6.
Durch die in die Einsetzöffnung 8 hineinreichende Zwischenschicht 13 wird die Gelenkkugel 12 bzw. die Lagerschale 1 in deren oberen Bereich übergriffen und die Einsetzöffnung 8 so weit verengt, daß ein sicherer Halt der Lagerschale 1 und somit auch der Gelenkkugel 12 im Kugelhohlraum 7 erreicht wird. Durch die Zwischenschicht 13 wird ein sicherer Toleranzausgleich erreicht, der bei der Herstellung der Gelenkkugel 12, der Lagerschale 1 und des Kugelhohlraums 7 als Einzelelemente auch bei Anwendung höchster Präzision nicht erreichbar wäre.Through the intermediate layer 13 extending into the insertion opening 8, the joint ball 12 or the bearing shell 1 is overlapped in its upper region and the insertion opening 8 is narrowed to such an extent that the bearing shell 1 and thus also the joint ball 12 in the ball cavity 7 are held securely. The intermediate layer 13 achieves a safe tolerance compensation, which would not be achievable in the manufacture of the joint ball 12, the bearing shell 1 and the ball cavity 7 as individual elements even with the highest precision.
Die Lagerschale 1 kann ein- oder mehrfach geschlitzt ausgeführt sein. Dies bewirkt eine bessere Verankerung derselben mit dem hinterspritzten Material.The bearing shell 1 can be designed with one or more slits. This results in a better anchoring of the same with the back-injected material.
Die gemäß Fig. 2 an der Lagerschale 1 angeformte Manschette 2 legt sich beim Einsetzen der Gelenkkugel 12 an den Kugelzapfen 11 an. Die Manschette 2, die bevorzugt die Form eines Faltenbalges aufweist, wird mittels eines eingesetzten Federringes 14 dicht an den Kugelzapfen 11 angedrückt.The sleeve 2 formed on the bearing shell 1 according to FIG. 2 rests on the ball stud 11 when the joint ball 12 is inserted. The cuff 2, which preferably has the shape of a bellows, is pressed tightly against the ball stud 11 by means of an inserted spring ring 14.
Der Flansch 5 der Lagerschale 1 liegt bei der Ausführung gemäß Fig. 2 auf einer Stützfläche 15 des Kugelgelenkgehäuses 6 auf . Gemäß einer vorteilhaften Ausgestaltung der Erfindung weist die Innenwand des Kugelhohlraumes 7 eine unbearbeitete, rauhe Oberfläche auf. Diese Oberfläche kann eine unbearbeitete Oberfläche eines Metallgußteils, eines Blechformteils, eines Kaltfließpreßteils, eines Schmiedeteils oder dgl. sein. Diese Oberfläche kann, gegebenenfalls zusätzlich, auch Nuten, Rillen, Riefen oder dgl. aufweisen.The flange 5 of the bearing shell 1 rests on a support surface 15 of the ball joint housing 6 in the embodiment according to FIG. 2. According to an advantageous embodiment of the invention, the inner wall of the ball cavity 7 has an unprocessed, rough surface. This surface can be an unprocessed surface of a metal casting, a sheet metal part, a cold extrusion, a forged part or the like. This surface can, if necessary additionally, also have grooves, grooves, grooves or the like.
Vorteilhaft besteht das Kugelgelenkgehäuse 6 aus einem einheitlichen Bauteil.The ball joint housing 6 advantageously consists of a single component.
Die Lagerschale 1 und/oder die Zwischenschicht 13 bestehen aus einem polymerisierenden Kunststoff, insbesondere einem Thermoplast, vorzugsweise aus einem der Kunststoffe Poly- ethylen, Polypropylen, Polyoxymethylen, Polyethersulfon, Polyetheretherketon oder Polyamid.The bearing shell 1 and / or the intermediate layer 13 consist of a polymerizing plastic, in particular a thermoplastic, preferably of one of the plastics polyethylene, polypropylene, polyoxymethylene, polyether sulfone, polyether ether ketone or polyamide.
Vorzugsweise besteht die Lagerschale 1 aus einem unverstärkten Kunststoff, während die Zwischenschicht 13 mit einem Füllstoff, beispielsweise mit einem oder mehreren mineralischen Füllstoffen, gegebenenfalls aus oder auf der Basis von Glas, beispielsweise in Form von Glasfasern, Glaskugeln oder mineralischen Verbindungen in anderer Form und/oder Verbindungen, verstärkt sein kann.The bearing shell 1 preferably consists of an unreinforced plastic, while the intermediate layer 13 with a filler, for example with one or more mineral fillers, optionally made of or based on glass, for example in the form of glass fibers, glass balls or mineral compounds in another form and / or connections, can be reinforced.
Die erfindungsgemäße Einheit aus Lagerschale 1 und Manschette 2 kann auch bei Kugelgelenken Anwendung finden, bei denen keine Zwischenschicht 13 vorgesehen ist und bei denen die Fixierung der Gelenkkugel 12 mit der Lagerschale 1 durch Einrollieren eines Randes des Kugelgelenkgehäuses 6 oder in sonst bekannter Weise erfolgt. Die erfindungsgemäße Einheit aus Lagerschale 1 und Manschette 2 kann auch bei anderen Lageranwendungen, wie zum Beispiel bei Radial- oder Axiallagern vorgesehen sein. The unit comprising the bearing shell 1 and the sleeve 2 can also be used in ball joints in which no intermediate layer 13 is provided and in which the joint ball 12 is fixed to the bearing shell 1 by rolling in an edge of the ball joint housing 6 or in any other known manner. The unit according to the invention comprising the bearing shell 1 and the sleeve 2 can also be provided in other bearing applications, such as, for example, in radial or axial bearings.
