Abstract
The invention relates to an element for supporting units that can vibrate, in particular, for supporting a hydraulic oil cooler, having a body (1) made from rubber with an essentially parallelepiped shape which is enclosed by bent sheet metal pieces (2) which essentially cover said body, leaving six inclined diametrically opposed exposed body edges (I1) which run into each other in a groove, said pieces being connected to the body (1) by vulcanisation.
Description
Element zum Abstützen schwingungsfähiger Aggregate Element for supporting vibratory aggregates
Die Erfindung betrifft ein Element zum Abstützen schwingungsfähiger Aggregate, insbesondere zum Abstützen eines Hy- draulik-Ölkühlers .The invention relates to an element for supporting vibratory aggregates, in particular for supporting a hydraulic oil cooler.
Derartige Aggregate wurden bisher mit Hilfe von zwischen dem Aggregat und einem Tragrahmen zwischengeschalteten, im wesentlichen zylindrischen Gummielementen schwingungsdämpfend befestigt. Diese mit Hilfe einer Schraubverbindung montierten Elemente können bei kleinem Eigenvolumen relativ große Schwingungskräfte in Richtung der Befestigungsachse bzw. senkrecht zu dem Aggregat und dem Tragrahmen aufnehmen. Schwingungskräf- te, die senkrecht zur Befestigungsachse, also parallel zu dem Tragrahmen auftreten, werden dagegen relativ schlecht oder gar nicht aufgenommen. In der Praxis hat sich auch gezeigt, daß sich die Vulkanisierverbindung zwischen dem Gummielement und Deckplatten aus Metall, welche die Befestigungsschraubenzapfen aufnehmen, in relativ kurzer Zeit durch Alterung auflöst.Such aggregates have hitherto been mounted vibration-damping with the aid of interposed between the unit and a support frame, substantially cylindrical rubber elements. These elements mounted with the aid of a screw connection can absorb relatively large vibration forces in the direction of the attachment axis or perpendicular to the assembly and the support frame with a small intrinsic volume. Vibration forces that occur perpendicular to the mounting axis, ie parallel to the support frame, are relatively poor or not recorded. In practice, it has also been found that the Vulkanisierverbindung between the rubber element and cover plates made of metal, which receive the mounting screw pin, dissolves in a relatively short time by aging.
Die vorliegende Erfindung zielt darauf ab, ein Element der einleitend angegebenen Art zu schaffen, welches bei gleichem Bauvolumen wie die bekannten Elemente Schwingungskräfte in zumindest zwei aufeinander senkrechten Schwingungsrichtungen aufnehmen kann. Das erfindungsgemäße Dämpfungselement zeichnet sich dadurch aus, daß es einen Körper aus Gummi mit im wesentlichen parallelepipedischer Gestalt hat, der unter Freilassung von sechs schrägen, einander jeweils diametral gegenüberliegenden, in einem Zug ineinander übergehenden Körperkanten von die Körperflächen im wesentlichen abdeckenden Metallblechwinkeln eingefaßt ist, die mit dem Körper durch Vulkanisieren verbunden sind. Das erfindungsgemäße Element kann damit ohne weiteres auch Scherkräfte bzw. Radialschwingungskräfte aufnehmen und dämpfen.
Die Erfindung wird nachfolgend an einem Ausführungsbeispiel unter Bezugnahme auf die Zeichnung näher erläutert . Es zeigen: Fig.l eine Perspektivansicht des Abstützelementes gemäß der Erfindung und Fig.2 einen Schnitt nach der Linie II-II in Fig.l.The present invention aims to provide an element of the type described in the introduction, which can absorb vibration forces in at least two mutually perpendicular directions of vibration with the same volume of construction as the known elements. The damping element according to the invention is characterized in that it has a body made of rubber with a substantially parallelepipedic shape, which is surrounded by the release of six oblique, mutually diametrically opposite, in a train merging body edges of the body surfaces substantially covering sheet metal angles, the connected to the body by vulcanization. The element according to the invention can thus easily absorb and dampen shear forces or radial vibration forces. The invention will be explained in more detail using an exemplary embodiment with reference to the drawing. 1 shows a perspective view of the support element according to the invention and FIG. 2 shows a section along the line II-II in FIG.
Das gezeigte Abstützelement hat einen parallelepipedi- schen Körper 1 aus Gummi, der von zwei Metallwinkeln 2 umgeben ist, die sich je über eine Deckseite und zwei Schmalseiten des Körpers erstrecken und mit dem Körper durch Vulkanisieren verbunden sind. Wie die Zeichnung zeigt, bleiben sechs schräge, einander jeweils diametral gegenüberliegende Körperkanten 1', die in einem Zug ineinander übergehenden, frei . An den Deckseiten sind die Metallwinkel 2, vorzugsweise aus Stahl oder Messing, mit Gewindebohrungen 2 ' zur Aufnahme von (nicht gezeigten) Befestigungsschrauben versehen, mit welchen das Element einerseits an einem Tragrahmen und anderseits an einem abzustützenden Aggregat, wie einem Hydraulik-Ölkühler verbunden wird. Die erfindungsgemäße Ausbildung ermöglicht das Aufnehmen von Schwingungskräften, die im Betrieb z.B. eines Kraftfahrzeuges auf das Aggregat ausgeübt werden. Die gezeigte Konstruktion hat hohe Lebensdauer.

On the cover sides, the metal angles 2, preferably made of steel or brass, are provided with threaded bores 2 'for receiving fixing screws (not shown) to which the element is connected, on the one hand, to a support frame and, on the other hand, to a unit to be supported, such as a hydraulic oil cooler , The construction according to the invention makes it possible to absorb vibration forces which in operation, e.g. a motor vehicle are exerted on the unit.
