Description
Die Erfindung betrifft eine hydraulisch dämpfende Lagerbuchse mit einem topfförmigen Außengehäuse, in dem ein Innengehäuse mit einem anvulkanisiertem Tragkörper aus einem elastischen Material aufgenommen ist, der einen Lagerkern abstützt, wobei eine Arbeitskammer und eine Ausgleichskammer vorgesehen ist, die mit einer hydraulischen Flüssigkeit gefüllt sind und über einen Kanal miteinander verbunden sind.The The invention relates to a hydraulically damping bushing with a cup-shaped Outer casing, in an inner housing with a vulcanised support body is taken from an elastic material, the one bearing core supports, where a working chamber and a compensation chamber is provided which with a hydraulic fluid filled are and about a channel are connected together.
Hydraulisch dämpfende Lagerbuchsen, die auch als Hydrobuchsen bezeichnet werden, kommen bei der Lagerung von Motoren in Fahrzeugen zum Einsatz. Sie weisen ein kompaktes Design auf und sind kostengünstig herzustellen. Ein wesentlicher Schwachpunkt bisheriger Lagerbuchsen ist jedoch die Krafteinleitung in das den Tragkörper umgebende Gehäuse. Im Stand der Technik werden zur Krafteinleitung aufwendige Blechstrukturen verwendet, die mit Gummi umvulkanisiert werden müssen.hydraulic absorbing Bushings, which are also referred to as hydraulic bushings, come in the storage of engines in vehicles used. You assign compact design and are inexpensive to manufacture. A major weakness previous bearing bushes, however, is the introduction of force in the supporting body surrounding housing. In the state of the art, elaborate sheet metal structures are used to introduce force used, which must be vulcanized with rubber.

der
Aufgabe der Erfindung ist des deshalb, eine Lagerbuchse anzugeben, bei der eine optimale Krafteinleitung in das umgebende Gehäuse ermöglicht wird und die kostengünstig herstellbar ist.task The invention therefore is to provide a bushing in which an optimal introduction of force into the surrounding housing is made possible and the cost-effective can be produced.
Zur Lösung dieser Aufgabe wird bei einer hydraulisch dämpfenden Lagerbuchse der eingangs genannten Art vorgeschlagen, dass das Außengehäuse und das Innengehäuse im Wesentlichen quaderförmig ausgebildet sind und sich gegenüberliegende, ebene Stützflächen aufweisen, dass das Innengehäuse zwei Ausgleichskammeraussparungen aufweist, die durch eine stegförmige Stützfläche voneinander getrennt sind, dass im Bereich der Aussparungen die Ausgleichsmembran der Ausgleichskammer anvulkanisiert ist und dass die Ausgleichskammer in zwei Ausgleichskammerbereiche unterteilt ist, die miteinander verbunden sind und in das Außengehäuse nach außen eingeprägt sind.to solution This object is achieved with a hydraulically damping bushing of the aforementioned Art suggested that the outer casing and the inner casing essentially cuboid are formed and opposite, have flat support surfaces, that the inner case has two compensation chamber recesses, which by a web-shaped support surface from each other are separated, that in the area of the recesses the compensation membrane the compensation chamber is vulcanised and that the compensation chamber is divided into two compensation chamber areas, which together are connected and in the outer housing after Outside imprinted are.
Durch die erfindungsgemäße Ausgestaltung der Stützflächen wird eine Maximierung der Anschlagsflächen erreicht, wodurch die Kräfte durch das Innengehäuse direkt auf das Außengehäuse übertragen werden. Somit wird die Krafteinleitung verbessert. Durch die quaderförmige Ausbildung des Außengehäuses und des Innengehäuses wird ein besonders kompaktes Design erzielt. Zudem wird durch die Unterteilung der Ausgleichskammer in zwei Ausgleichskammerbereiche, die miteinander verbunden sind, ein ausreichend großes Volumen für die Ausgleichskammer erreicht.By the embodiment of the invention Support surfaces is a maximization of the stop surfaces achieved, reducing the forces through the inner housing transferred directly to the outer housing become. Thus, the introduction of force is improved. Due to the cuboid training of the outer casing and of the inner casing a particularly compact design is achieved. In addition, by the Subdivision of the compensation chamber into two compensation chamber areas, which are interconnected, a sufficiently large volume for the compensation chamber reached.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.advantageous Embodiments of the invention are specified in the subclaims.
In vorteilhafter Ausgestaltung weist der Tragkörper im Bereich des Lagerkerns eine im wesentlichen ebene Anschlagfläche auf, die dem Boden des Außengehäuses gegenüberliegt.In advantageous embodiment, the support body in the region of the bearing core a substantially planar abutment surface opposite the bottom of the outer housing.
In weiterer vorteilhafter Ausgestaltung verläuft der Kanal seitlich versetzt zu den Stützflächen in einem Randbereich des Außengehäuses. Hierdurch wird erreicht, dass die Krafteinleitung nicht in Dichtungsbereichen des Kanals erfolgt.In Further advantageous embodiment, the channel is laterally offset to the support surfaces in one Edge area of the outer housing. This will ensures that the force is not introduced into sealing areas of the Channel is done.
