Hydraulisch dämpfendes GummilagerHydraulically damping rubber mount
Die Erfindung bezieht sich auf ein Gummilager gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a rubber mount according to the preamble of claim 1.
Ein derartiges Gummilager ist aus der DE-OS 32 46 587 bekannt. Bei diesem Gummilager sind die beiden Kammern sowie der Ausgleichsraum in axialer Richtung übereinander angeordnet. Dadurch ist die Bauhöhe des Gummilagers sehr groß. Diese Bauhöhe vergrößert sich noch durch die große Dicke der die Drosselöffnung aufnehmenden Trennwand zwischen den Kammern. Das bekannte Gummilager hat daher in Axialrichtung einen Platzbedarf, der insbesondere bei seiner Verwendung als Motorlager nicht immer zur Verfügung steht.Such a rubber mount is known from DE-OS 32 46 587. The two chambers are in this rubber mount and the compensation space arranged one above the other in the axial direction. As a result, the height of the rubber mount is very high great. This overall height is increased by the great thickness of the dividing wall accommodating the throttle opening between the chambers. The known rubber mount therefore has a space requirement in the axial direction, which is particularly important in its use as an engine mount is not always available.
Der Erfindung liegt die Aufgabe zugrunde, ein derartiges Gummilager so auszubilden, daß seine axiale Bauhöhe wesentlich verringert ist.The invention is based on the object of designing such a rubber mount so that its overall axial height is significantly reduced.

Die Aufgabe ist erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst.According to the invention, the object is achieved by the characteristics of claim 1 specified features solved.
Das erfindungsgemäße Gummilager weist gegenüber dem bekannten Gummilager, bei dem sowohl die beiden Kammern wie der Ausgleichsraum die Bauhöhe mitbestimmen, eine bedeutend geringere Bauhöhe auf, da nämlich nur eine, nämlich die innere Kammer den axialen Abstand zwischen den beiden Stirnwänden und damit die Bauhöhe bestimmt, während die andere Kammer und der Ausgleichsraum die innere Kammer umschließen und nichts zur Bauhöhe beitragen. The rubber mount according to the invention has the opposite of the known rubber mount, in which both the two chambers like the compensation space co-determine the construction height, a significantly lower construction height, since there is only one, namely the inner chamber determines the axial distance between the two end walls and thus the overall height, while the other chamber and the compensation space enclose the inner chamber and do not contribute to the overall height.
Eine besonders platzsparende und dazu geschützte Lage des Ausgleichsraums, der benachbarten Kammer und des Faltenbalges ist durch die Ausbildung gemäß dem Anspruch 2 gegeben.A particularly space-saving and protected location of the compensation space, the adjacent chamber and the Bellows is given by the training according to claim 2.
Im Anspruch 3 ist eine günstige Ausbildung und Lage der die beiden Kammern verbindenden Drosselöffnung angegeben.In claim 3, a favorable design and location of the throttle opening connecting the two chambers is specified.
Im Anspruch 4 ist eine Ausbildung des Gummilagers angegeben, die mit geringem Platzbedarf und ohne Vergrößerung der Bauhöhe eine Möglichkeit zur Aufnahme von Schwingungen hoher Frequenzen ohne Ansprechen der Dämpfung schafft.In claim 4, an embodiment of the rubber bearing is specified, which requires little space and without enlargement the overall height creates the possibility of absorbing vibrations of high frequencies without responding to the damping.
Im folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. In the following the invention is explained in more detail with reference to an embodiment shown in the drawing.

Ein im Querschnitt dargestelltes, als Motorlager für eine nicht dargestellte Brennkraftmaschine dienendes Gummilager 1 weist eine obere mit einer Stirnwand 2 fest verbundene Aufnahme 3 und eine untere Aufnahme in einem Kern 5 auf. Zwischen diesem und einem Innenring 6 ist ein gummielastisches Federelement 7 einvulkanisiert. Der Innenring 6 ist an seinem unteren äußeren Rand über ein Stahlband 8 fest mit einem einstückig mit der Stirnwand 2 ausgebildeten Mantel 9 verbunden. Der zwischen dem Innenring 6 und dem Mantel 9 bestehende Ringraum wird nach oben von einer Kanalwand 10 abgeschlossen, die einerseits mit dem oberen inneren Rand des Innenringes 6 und andererseits mit der Stirnwand 2 und dem Mantel 9 in derem Übergang fest verbunden ist. Dieser Ringraum wird von einem Faltenbalg in einen Ausgleichsraum 12, der über Löcher 13 im Mantel 9 mit der Umgebungsluft in Verbindung steht, und eine daran benachbarte äußere Kammer 14 geteilt. Der Faltenbalg ist mit seinem unteren Rand zwischen dem Innenring 6 und dem Mantel 9 sowie mit seinem oberen Rand zwischen dem Mantel 9 und der Kanalwand 10 eingespannt. Eine von der Stirnwand 2, einer Stirnwand 15 des Kerns 5 und einer Begrenzungswand 16 des Federelements 7 begrenzte innere Kammer 17 ist von der äußeren Kammer 14 durch die Kanalwand 10 und den Innenring 6 getrennt.A shown in cross section, serving as an engine mount for an internal combustion engine, not shown Rubber mount 1 has an upper receptacle 3 firmly connected to an end wall 2 and a lower receptacle in a core 5. A rubber elastic spring element 7 is vulcanized in between this and an inner ring 6. The inner ring 6 is firmly in one piece with a steel band 8 at its lower outer edge with the end wall 2 formed jacket 9 connected. The one between the inner ring 6 and the jacket 9 existing annulus is closed at the top by a channel wall 10, the one hand with the upper inner edge of the inner ring 6 and on the other hand firmly connected to the end wall 2 and the jacket 9 in their transition is. This annular space is converted by a bellows into a compensation space 12, which is formed via holes 13 in the jacket 9 is in communication with the ambient air, and an adjacent outer chamber 14 is shared. The bellows is with its lower edge between the inner ring 6 and the jacket 9 and with its upper edge between the Cladding 9 and the duct wall 10 clamped. One of the end wall 2, one end wall 15 of the core 5 and one Boundary wall 16 of the spring element 7 bounded inner chamber 17 is from the outer chamber 14 by the Channel wall 10 and the inner ring 6 separately.
Die beiden Kammern 14 und 17 sind mit Dämpfungsflüssigkeit gefüllt, die über einen durch die Kanalwand 10 gebildeten Ringkanal 18 von einer KammerThe two chambers 14 and 17 are filled with damping fluid that passes through the duct wall 10 formed annular channel 18 by a chamber

zur anderen überströmen kann. Der Ringkanal 18 weist dazu an entgegengesetztenUmfangsstellen je eine Öffnung 19, 20 in jeweils eine Kammer 14, 17 auf, so daß er als Drosselöffnung wirkt, die der Dämpfung von insbesondere niederfrequenten Schwingungen großer Amplitude dient.can overflow to the other. For this purpose, the annular channel 18 has an opening each at opposite circumferential points 19, 20 in each case a chamber 14, 17, so that it acts as a throttle opening, the damping of in particular is used for low-frequency oscillations of large amplitude.
Zur Vermeidung der Übertragung von hochfrequenten Schwingungen geringer Amplitude, also insbesondere von Geräuschschwingungen, ist zwischen der Kanalwand und einem Flansch 21 des Innenrings 6 eine Ringmembran mit Spiel eingesetzt, die durch über den Umfang verteilte Löcher 23 und 24 in der Kanalwand 10 und dem Flansch 21 von der in den Kammern 14 und 17 befindlichen Dämpfungsflüssigkeit beaufschlagbar und in Axialrichtung auslenkbar ist. Damit stellt das erfindungsgemäße Gummilager im Bereich der Geräuschschwingungen eine weiche Lagerung mit geringer Eigendämpfung dar, die eine gute Geräuschisolierung bewirkt.To avoid the transmission of high-frequency vibrations of low amplitude, in particular of noise vibrations, an annular membrane is between the duct wall and a flange 21 of the inner ring 6 used with play, through holes 23 and 24 distributed over the circumference in the channel wall 10 and the Flange 21 can be acted upon by the damping fluid located in chambers 14 and 17 and in the axial direction is deflectable. Thus, the rubber mount according to the invention is in the area of noise vibrations a soft mounting with low self-damping, which causes good noise insulation.
Das erfindungsgemäße Gummilager 1 weist eine sehr geringe Bauhöhe auf, da diese im wesentlichen nur von den Höhen der inneren Kammer .17 und des Federelements 7 bestimmt wird. Dagegen beeinflussen die äußere Kammer und der Ausgleichsraum 12 die Bauhöhe nicht ungünstig, da sie als Ringräume die innere Kammer 17 und das Federelement 7 umschließen. Auch die Ringmembran 22 und ihre Lagerung sowie der radial dahinter angeordnete Ringkanal 18 vergrößern nicht die Bauhöhe des Gummilagers 1 .The rubber mount 1 according to the invention has a very low overall height, since this is essentially only of the Heights of the inner chamber .17 and the spring element 7 is determined. In contrast, affect the outer chamber and the compensation space 12 does not have an unfavorable overall height, since it is the inner chamber 17 and the spring element as annular spaces 7 enclose. The annular diaphragm 22 and its mounting as well as the one arranged radially behind it The ring channel 18 does not increase the overall height of the rubber mount 1.
