Abstract
Description
Die Erfindung betrifft ein Metall-Elastomer-Verbindungselement nach dem Oberbegriff des Patentanspruchs.The invention relates to a metal-elastomer connecting element according to the preamble of the claim.
Derartige Verbindungselemente sind beispielsweise aus DE-GM 16 10 135, US 18 28 402 und US 18 71 963 bekannt. Solche Ver bindungselemente werden unter anderem im Kraftfahrzeugbau zur geräusch- und schwingungsentkoppelten Befestigung von Aggre gaten an den Fahrgestellen bzw. der Karosserie verwendet.Such connecting elements are for example from DE-GM 16 10 135, US 18 28 402 and US 18 71 963 known. Such ver Binding elements are used, among other things, in motor vehicle construction Noise and vibration decoupled fastening from Aggre were used on the chassis or the body.
Die Erfindung beschäftigt sich mit dem Problem, den Aufbau derartiger Verbindungselemente rationeller zu gestalten und dabei gleichzeitig deren Handhabung beim Anbringen an die zu verbindenden Teile zu verbessern.The invention deals with the problem of construction to design such connecting elements more rationally and at the same time their handling when attaching to the to improve connecting parts.
Ein Lösung dieses Problems zeigt das Kennzeichen des Patent anspruchs auf.The characteristic of the patent shows a solution to this problem demanding.
Ein Vorteil dieser Ausführung besteht insbesondere darin, daß die beiden durch ein Elastomer miteinander verbundenen Metall träger als gleiches Teil ausgebildet sein können, wodurch die Herstellung derartiger Verbindungselemente rationalisiert wird. Ein weiterer Vorteil ergibt sich aus der Ausformung und gegenseitigen Anordnung der Metallträger, durch die das Ver bindungselement ein Sechskantprofil zum Ansetzen eines entsprechenden üblichen Schraubenschlüssels, insbesondere eines Sechskantsteckschlüssels, erhält. An advantage of this embodiment is in particular that the two metal connected by an elastomer carrier can be formed as the same part, whereby the Production of such fasteners is rationalized. Another advantage results from the shape and mutual arrangement of the metal supports through which the Ver binding element a hexagon profile for attaching a corresponding conventional wrench, in particular a hexagon socket wrench.
Die Verbindung zwischen den Metallträgern und dem Elastomer kann insbesondere festigkeitsmäßig ausreichend stabil herge stellt werden. Zu diesem Zweck ist die Elastomermasse mit den Metallträgern durch Vulkanisation verbunden.The connection between the metal supports and the elastomer can be particularly stable in terms of strength be put. For this purpose, the elastomer mass with the Metal supports connected by vulcanization.
Die gute Verbindung zwischen der Elastomermasse und dem Me tallträger erlaubt auch bei festigkeitsmäßig hoher Bean spruchung den Einsatz einer relativ weichen Elastomermasse, die für eine gute Geräuschabsorption erwünscht ist.The good connection between the elastomer mass and the me tall girder allows even with high bean strength the use of a relatively soft elastomer mass, which is desirable for good noise absorption.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is in the drawing shown.

Das Metall-Elastomer-Verbindungselement ist aufgebaut aus zwei mit Abstand gegenüberliegenden Metallträgern 1. Jeder Metall träger 1 besitzt einen angeschweißten Gewindebolzen 2. Der Raum zwischen den beiden gegenüberliegenden Metallträgern 1 ist mit einem relativ weichen Elastomer 3 ausgefüllt, das mit den Metallträgern 1 durch Vulkanisieren verbunden ist.The metal-elastomer connecting element is made up of two metal carriers 1, which are located opposite one another at a distance. Each metal carrier 1 has a welded threaded bolt 2nd The space between the two opposite metal supports 1 is filled with a relatively soft elastomer 3 , which is connected to the metal supports 1 by vulcanization.
Die Basisfläche jedes Metallträgers 1 ist sechseckig. An je weils drei nicht benachbarten Kanten dieser Basisfläche sind rechtwinklig zu dieser Basisfläche Laschen 4 abgeknickt.The base surface of each metal carrier 1 is hexagonal. On each three non-adjacent edges of this base surface tabs 4 are bent at right angles to this base surface.
Die jeweils zwei gegenüberliegenden das Elastomer 3 um schließenden Metallträger 1 sind gleich geformt und jeweils um 60 Winkelgrad umfangsmäßig gegeneinander verdreht zur Aufnahme des Elastomers 3 angeordnet. Durch diese gegenseitig verdrehte Anordnung sind umfangsmäßig alle sechs Flächen aus dem Metall der Metallträger 1. Dadurch ist praktisch ein Sechskant gege ben, an den ein üblicher Schraubenschlüssel zum Anbringen des Verbindungselementes an einem Halteteil ermöglicht wird.The two opposite metal supports 1 , which close the elastomer 3 , are shaped identically and are each rotated circumferentially by 60 degrees to accommodate the elastomer 3 . Due to this mutually twisted arrangement, all six surfaces of the metal are circumferentially made of the metal carrier 1 . This is practically a hexagon ben, to which a conventional wrench for attaching the connecting element to a holding part is made possible.
Da die Laschen 4 umfangsmäßig nicht aneinanderstoßen dürfen, sind die Kanten des Metallträgers 1, an denen sich Laschen 4 befinden, kürzer als die drei übrigen Kanten, an denen sich jeweils keine Laschen befinden.Since the tabs 4 are not allowed to abut circumferentially, the edges of the metal carrier 1 , on which tabs 4 are located, are shorter than the three other edges, on which there are no tabs in each case.
Durch die erfindungsgemäße Umklammerung des Elastomers 3 durch die mit seitlichen Laschen 4 versehenen Metallträger 1 kann das Verbindungselement hohe Zug- und Schubkräfte sicher aufnehmen.Due to the clasping of the elastomer 3 according to the invention by the metal carrier 1 provided with lateral tabs 4 , the connecting element can reliably absorb high tensile and shear forces.
Derartige Verbindungselemente eignen sich insbesondere zur Anbringung von Aggregaten an der Karosserie von Kraft fahrzeugen, wenn Schwingungen und Geräusche, die von den be treffenden Aggregaten, wie beispielsweise einer Wischeranlage, erzeugt werden, von der Karosserie weitgehend ferngehalten werden sollen.Such connecting elements are particularly suitable for Attaching aggregates to the body of Kraft vehicles when vibrations and noises emitted by the be hitting units, such as a wiper system, generated, largely kept away from the body should be.
