Zur federnd-elastischen Abstützung beispielsweise des Motors in einem Kraftfahrzeug weist ein Hydrolager üblicherweise einen Tragkörper aus elastomerem Material auf. Dieser Tragkörper befindet sich zwischen abstandsvariabel zueinander angeordneten Befestigungsmitteln. Der Innenraum des Lagers ist durch eine starre Platte in zwei volumenveränderliche Kammern - eine Arbeitskammer und eine Ausgleichskammer - geteilt. Zur Bedämpfung tieffrequenter Schwingungen sind die beiden Kammern über einen Dämpfungskanal, auch Drosselkanal genannt, miteinander verbunden. Gattungsgemäße Weiterentwicklungen von Hydrolagern weisen außer einem elastischen Tragkörper und einem Dämpfungskanal meist eine Entkopplungsmembran zur Isolation höherfrequenter Schwingungen auf und können auch einen steuerbaren Bypass aufweisen. For resiliently elastic support, for example, of the engine in a motor vehicle, a hydraulic bearing usually has a support body made of elastomeric material. This support body is located between fastening means which are arranged at variable distances from one another. The interior of the bearing is divided by a rigid plate into two volume-variable chambers - a working chamber and a compensation chamber. To dampen low-frequency vibrations, the two chambers are connected to one another via a damping channel, also known as a throttle channel. Generic further developments of hydraulic bearings have, in addition to an elastic support body and a damping channel, usually a decoupling membrane for isolating higher-frequency vibrations and can also have a controllable bypass.

Der Erfindung liegt die Aufgabe zugrunde, ein Lager der eingangs beschriebenen Art mit Bypass weiter zu vereinfachen und Dichtigkeitsprobleme zu vermeiden.The invention is based on the object of further simplifying a bearing of the type described above with a bypass and of avoiding sealing problems.
Diese Aufgabe wird dadurch gelöst, dass das Hydrolager einen Bypass aufweist, der als Öffnung in der Drosselscheibe ausgebildet ist und die Ausgleichskammer durch eine sackförmige Erweiterung der Kombinationsmembran gegen den Bypass abgegrenzt ist, wobei die sackförmige Erweiterung eine zusätzliche Kammer, nämlich die Bypasskammer bildet.This object is achieved in that the hydraulic bearing has a bypass, which is designed as an opening in the throttle disc and the compensation chamber is delimited from the bypass by a sack-shaped extension of the combination membrane, the sack-shaped extension forming an additional chamber, namely the bypass chamber.
Dadurch, dass die Bypasskammer durch die sackförmige Erweiterung der Kombinationsmembran als einstückiger Bestandteil der Kombinationsmembran bildbar ist, ergibt sich auch bei Vorhandensein eines Bypasses der Vorteil, dass die Gefahr von Undichtigkeiten oder Fehlmontagen gering ist. Das Hydrolager kann auch bei einteiliger Membran als schaltbares Bypass-Hydrolager genutzt werden. Die Membranbereiche liegen wegen der Einstückigkeit auch immer lagerichtig zueinander.The fact that the bypass chamber can be formed as a one-piece component of the combination membrane due to the sack-shaped expansion of the combination membrane results in the advantage that the risk of leaks or incorrect assembly is low, even if a bypass is present. The hydromount can also be used as a switchable bypass hydromount with a one-piece membrane. Because of the one-piece nature, the membrane areas are always in the correct position to one another.
Anhand der Zeichnung wird nachstehend ein Beispiel der Erfindung näher erläutert.An example of the invention is explained in more detail below with reference to the drawing.
