Die Erfindung bezieht sich auf eine Lagerbuchse, bestehend aus einem kugelförmigen Innenteil und einem, der Aufnahme des Innenteils dienenden Gehäuse sowie einem dazwischen angeordneten elastischen Zwischenteil.The invention relates to a bearing bush consisting of a spherical inner part and a housing serving to receive the inner part and an elastic intermediate part arranged between them.
Es sind bereits Lagerungen in Form von Kugelgelenken bekannt, bei denen ein Kugelzapfen und ein Gehäuse aus Kunststoff vorgesehen sind, wobei der Kugelzapfen dreh- und schwenkbar gehalten ist. Derartige Kugelgelenke sind jedoch nicht für die Anordnung in Fahrwerken von Kraftfahrzeugen geeignet.Bearings in the form of ball joints are already known, in which a ball pin and a housing made of plastic are provided, the ball pin being rotatably and pivotably held. However, such ball joints are not suitable for arrangement in the undercarriage of motor vehicles.
Aufgabe der Erfindung ist es, eine Lagerbuchse zu schaffen, welche zur Dämpfung von Schwingungen in Fahrwerksteilen angeordnet werden kann und die bei axialer und radialer Kraftaufnahme hart und bei kardanischen Auslenkungen weich ausgebildet ist.The object of the invention is to provide a bearing bush which can be arranged for damping vibrations in chassis parts and which is hard in the case of axial and radial force absorption and soft in the case of cardanic deflections.
Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, dass das kugelförmige Innenteil mit einem vor der Montage kegelstumpfförmig ausgebildeten elastischen Zwischenteil nach der Montage des einteiligen Gehäuses in den Zwischenraum zwischen kugelförmigem Innenteil und Gehäuse hineinverformt wird.To achieve this object, it is provided according to the invention that the spherical inner part with a frustoconical elastic intermediate part before assembly after assembly of the one-piece housing in the The space between the spherical inner part and the housing is deformed.
Hierbei ist von Vorteil, dass durch die kugelförmige Gestaltung des Innenteiles und der entsprechenden Aufnahme in einem äußeren Gehäuse das elastische Zwischenteil in etwa mit einer gleichförmigen Wandstärke versehen ist, so dass diese Lagerbuchse in Axial- und Radialrichtung hart ausgebildet ist, wobei jedoch kardanische Auslenkungen problemlos ausgeführt werden können. Darüber hinaus ist von Vorteil, dass durch die einteilige Ausführung des Gehäuses nicht nur wenige Bauteile, sondern auch eine einfache Montage der Lagerbuchse möglich ist.The advantage here is that the spherical design of the inner part and the corresponding receptacle in an outer housing provides the elastic intermediate part with an approximately uniform wall thickness, so that this bearing bush is hard in the axial and radial directions, but cardanic deflections are problem-free can be executed. Another advantage is that the one-piece design of the housing enables not only a few components, but also simple assembly of the bearing bush.
Nach einem weiteren wesentlichen Merkmal ist vorgesehen, dass das elastische Zwischenteil mindestens zweiteilig ausgebildet ist.According to a further essential feature, it is provided that the elastic intermediate part is formed at least in two parts.

Die in den Figuren 1 und 2 dargestellte Lagerbuchse besteht im wesentlichen aus dem Gehäuse 1 , dem Innenteil 4 und dem dazwischen angeordneten elastischen Zwischenteil 3. Über die Halteelemente 2a und 2b ist das elastische Zwischenteil 3 im Gehäuse 1 fixiert, wobei die Außenwandung des Gehäuses 1 ein abgewinkeltes Ende 5 und ein umgebördeltes Ende 7 aufweist. Die Halteelemente 2a und 2b sind mit dem elastischen Zwischenteil 3 fest verbunden, während sie mit dem Gehäuse 1 in Ausnehmungen 6a bzw. 6b arretiert sind. Das elastische Zwischenteil 3 ist darüber hinaus mit dem Innenteil 4 ebenfalls fest verbunden, z.B. durch Vulkanisation.The bearing bush shown in FIGS. 1 and 2 essentially consists of the housing 1, the inner part 4 and the elastic intermediate part 3 arranged between them. The elastic intermediate part 3 is fixed in the housing 1 by means of the holding elements 2a and 2b, the outer wall of the housing 1 has an angled end 5 and a flanged end 7. The holding elements 2a and 2b are firmly connected to the elastic intermediate part 3, while they are locked with the housing 1 in recesses 6a and 6b. The elastic intermediate part 3 is also firmly connected to the inner part 4, e.g. through vulcanization.
Aus den Figuren 3 bis 5 ist ein Innenteil 4 zu entnehmen, wobei das elastische Zwischenteil aus den einzelnen Teilen 3a und 3b besteht. Im Endbereich des Teiles 3a ist das Halteelement 2a angeordnet, welches aus Kunststoff besteht und wie die Figur 4 zeigt mit einer Verzahnung 8 versehen ist. Die dadurch entstehende Elastizität ermöglicht die Montage in den Hinterschnitt des Außenteils. Zusätzlich ist der Kunststoff ring noch durch Vulkanisation mit dem elastischen Zwischenteil 3 verbunden.An inner part 4 can be seen from FIGS. 3 to 5, the elastic intermediate part consisting of the individual parts 3a and 3b. Arranged in the end region of part 3a is the holding element 2a, which consists of plastic and, as FIG. 4 shows, is provided with teeth 8. The resulting elasticity enables assembly in the undercut of the outer part. In addition, the plastic ring is still connected to the elastic intermediate part 3 by vulcanization.
Auf der Gegenseite ist das Teil 3b des elastischen Zwischenteiles 3 mit einem Halteelement 2b versehen, wobei dieser Haltering 2b aus Metall hergestellt ist, damit eine einwandfreie Abstützung beim Bördelvorgang vorhanden ist, indem das umgebördelte Ende 7 nicht nur eine ausreichende Fixierung am Halteelement 2b sondern auch eine ausreichende Abstützung erfährt.On the opposite side, the part 3b of the elastic intermediate part 3 is provided with a holding element 2b, this holding ring 2b being made of metal, so that there is a perfect support during the flanging process by the flanged end 7 is not only adequately fixed to the holding element 2b but also adequately supported.
Aus der Figur 3 ist zu erkennen, dass die einzelnen Teile 3a und 3b des elastischen Zwischenteiles 3 in axialer Richtung um den Überstand X gegenüber dem Innenteil 4 hervorstehen. Nach der Montage ist der Zustand gemäß Figur 1 erreicht, indem das elastische Zwischenteil 3 derart komprimiert ist, so dass kein Überstand des elastischen Zwischenteiles 3 gegenüber dem Innenteil 4 vorhanden ist. Durch diese Komprimierung wird sowohl in Axial- als auch in Radialrichtung eine sehr harte Federrate erzielt. Dadurch dass, wie Figur 1 zeigt, das elastische Zwischenteil 3 nicht gegenüber dem Gehäuse 1 in axialer Richtung nach außen vorsteht ist eine einwandfreie kardanische Auslenkung möglich, ohne dass das elastische Zwischenteil 3 zwischen dem Innenteil 4 und dem Gehäuse 1 beschädigt, bzw. gequetscht wird. Die kardanische Ausführung ist damit verhältnismäßig sehr weich gehalten, bei einer hohen axialen und radialen Stei- figkeit.It can be seen from FIG. 3 that the individual parts 3a and 3b of the elastic intermediate part 3 protrude in the axial direction by the projection X relative to the inner part 4. After assembly, the state according to FIG. 1 is reached in that the elastic intermediate part 3 is compressed in such a way that the elastic intermediate part 3 does not protrude from the inner part 4. This compression results in a very hard spring rate in both the axial and radial directions. Because FIG. 1 shows that the elastic intermediate part 3 does not protrude outward in relation to the housing 1 in the axial direction, a perfect cardanic deflection is possible without the elastic intermediate part 3 being damaged or squeezed between the inner part 4 and the housing 1 , The cardanic design is therefore kept very soft, with a high axial and radial rigidity.
Aus der Figur 6 ist ein Gehäuse 1 zu entnehmen, bei dem die Ausnehmungen 6a sowie 6b zur Aufnahme der entsprechenden Halteelemente 2 ausgebildet sind. Die Ausnehmung 6a ist in Bezug auf das Gehäuse 1 mit einem Hinterschnitt versehen, in dem bei axialer Montage des Innenteiles 4 zusammen mit dem elastischen Zwischenteil 3 und dem aus Kunststoff hergestellten Halteelement 2a eine Verrastung in der Ausnehmung 6a erfolgt, so dass anschließend das gesamte Innenelement axial in das Gehäuse 1 eingebracht werden kann, so lange bis das aus Metall hergestellte Halteelement 2b in die Ausnehmung 6b gelangt, anschließend kann dann der Endbereich 7 umgebördelt werden. Aus der Figur 7 ist als Innenteil 4 ein kugelförmiges Element dargestellt, wobei dieses kugelförmige Element mit einer Bohrung zur Aufnahme in einem Fahrwerk versehen ist. Das kugelförmige Innenteil gemäß Figur 8 ist dagegen mit Zapfen 9 versehen, die wiederum der Aufnahme in einem Fahrwerk dienen können.A housing 1 can be seen from FIG. 6, in which the recesses 6a and 6b are designed to accommodate the corresponding holding elements 2. The recess 6a is provided with an undercut with respect to the housing 1, in which, when the inner part 4 is axially mounted together with the elastic intermediate part 3 and the plastic holding element 2a, the recess 6a is latched, so that the entire inner element then follows can be introduced axially into the housing 1 until the holding element 2b made of metal reaches the recess 6b, then the end region 7 can then be flanged. A spherical element is shown as inner part 4 in FIG. 7, this spherical element being provided with a bore for receiving in a chassis. The spherical inner part according to FIG. 8, on the other hand, is provided with pins 9, which in turn can be used to accommodate a chassis.
Aus der Figur 9 bis 11 ist als Einzelteil ein Halteelement 2a dargestellt, welches aus Kunststoff besteht, damit ein Einrasten in den Hinterschnitt 6a erfolgen kann. Hierzu muss sich das Halteelement 2a entsprechend in seinem Durchmesser elastisch verformen.From FIGS. 9 to 11, a holding element 2a is shown as an individual part, which is made of plastic so that it can snap into the undercut 6a. For this purpose, the holding element 2a must correspondingly deform elastically in its diameter.
Aus den Figuren 12 und 13 ist ein Halteelement 2b vorgesehen, welches aus Metall hergestellt ist, damit für einen Bördelvorgang des Endbereiches 7 des Außenteiles 1 ein entsprechendes Gegenlager geschaffen wird. Auch dieses Halteelement 2b ist mit dem elastischen Zwischenteil 3 durch Vulkanisation verbunden. Der ringförmige Ansatz 10 des Halteelementes 2b dient im Außenteil 1 zur axialen Fixierung des Innenteiles 4 mit dem elastischen Zwischenteil 3 in beide Richtungen. From FIGS. 12 and 13, a holding element 2b is provided, which is made of metal, so that a corresponding counter bearing is created for a flanging operation of the end region 7 of the outer part 1. This holding element 2b is also connected to the elastic intermediate part 3 by vulcanization. The annular extension 10 of the holding element 2b is used in the outer part 1 for axially fixing the inner part 4 with the elastic intermediate part 3 in both directions.
