A bypass (20) that is to be arranged parallel to the damping channel (12) and closable with a closure element (18) and a decoupling membrane (18) that also acts parallel to the damping channel (14) should be simple and uncomplicated. In addition, the decoupling membrane (18) should be positioned precisely and secure against slipping through. DOLLAR A For this purpose, the decoupling membrane (18) and the bypass closure element (18a) form a common, one-piece component (18, 18a), the central part of the membrane (18a), which serves as a bypass compensation membrane and closure element, preferably Is sack-shaped and forms a compensation chamber (10c) assigned to the bypass (20). DOLLAR A Not only applicable as an engine mount, but also as a socket in the chassis and assembly mounts.
Description
Die Erfindung betrifft ein als Hydrolager ausgebildetes Motorlager, wobei einem Dämpferkanal ein schaltbarer Bypass und eine Entkopplungsmembran parallelgeschaltet sind, – gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a motor bearing designed as a hydraulic bearing, wherein a damper channel a switchable bypass and a decoupling membrane connected in parallel are, - according to the generic term of claim 1.
Zur federnd-elastischen Abstützung 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 Dämpferkanal (Drosselkanal) miteinander verbunden.to resilient-elastic support The engine in a motor vehicle usually has a hydraulic bearing a support body made of elastomeric material. This support is located between spaced apart from each other arranged fasteners. Of the Interior of the warehouse is by a rigid plate in two variable volume Chambers - one Working chamber and a compensation chamber - divided. For damping low-frequency vibrations the two chambers are over a damper channel (Throttle channel) connected to each other.

Aufgabe der Erfindungtask the invention
Die Aufgabe der Erfindung besteht darin, ein Hydrolager zu beschreiben, das eine Entkopplungsmembran und einen schaltbaren Bypass aufweist, wobei der Teil des Hydrolagers, der die Entkopplungsmembran und den Bypass umfasst, einfach und unkompliziert aufgebaut ist und wobei die Entkopplungsmembran präzise und durchrutschsicher positioniert ist.The The object of the invention is to describe a hydraulic bearing, having a decoupling membrane and a switchable bypass, wherein the part of the hydraulic bearing, the decoupling membrane and the bypass includes, is simple and straightforward, and wherein the decoupling membrane precise and is positioned against slipping.
Lösung und VorteileSolution and advantages
Bei der erfindungsgemäßen Weiterentwicklung eines gattungsgemäßen Hydrolagers ist der Verschluss des Bypasses und die Entkopplungsmembran als ein einziges Bauteil ausgebildet. D. h.: Es müssen nicht viele verschiedene Einzelteile hergestellt werden. Die Montage des Hydrolagers gestaltet sich entsprechend einfach. Eine Reparaturanfälligkeit, wie sie bei einer aus zahlreichen Einzelteilen bestehenden Konstruktion zu erwarten ist, ist nicht gegeben. Insgesamt ist das erfindungsgemäße Lager bedeutend kostengünstiger als vergleichbare Exemplare.at the development of the invention a generic hydraulic bearing is the occlusion of the bypass and the decoupling membrane as formed a single component. That is, not many different things have to be done Items are manufactured. The assembly of the hydraulic bearing designed just as simple. A repair vulnerability, as with a expected to consist of numerous individual parts construction is not given. Overall, the bearing of the invention significantly cheaper as comparable copies.
Die sackförmige Ausbildung des Membran-Mittelteils stellt eine Bypass-Ausgleichsmembran dar, die eine separate Ausgleichskammer abschließt.The saccular Forming the diaphragm middle part represents a bypass compensation membrane, which completes a separate compensation chamber.
Wie aus der beigefügten Zeichnung ersichtlich, kann der in der Trennplatte befindliche Bypass als düsenförmig geformter Durchlasskanal statt als einfaches Loch ausgebildet sein. Dadurch ergibt sich ein zusätzlicher Tilgereffekt mit verbesserter Isolationswirkung.As from the attached Drawing can be seen, located in the partition plate bypass as nozzle-shaped Passage channel instead of being designed as a simple hole. Thereby there is an additional Tilger effect with improved insulation effect.
Die Materialauswahl der Entkopplungsmembran als flexible Platte ermöglicht eine akustische Entkopplung im Bereich der Entkopplungsfläche. Die Flexibilität des sackförmigen Mittelteils ermöglicht ein dichtendes Anlegen an die Zylinderinnenwand bei Evakuierung des Topfes.The Material selection of the decoupling membrane as a flexible plate allows a acoustic decoupling in the area of the decoupling surface. The flexibility of the bag-shaped middle part allows a sealing application to the cylinder inner wall during evacuation of the pot.
In jedem Fall kann die Dämpfungsfunktion wahlweise abgeschaltet werden.In In any case, the damping function can optionally be switched off.
Die Erfindung ist nicht nur für Motorlager sondern auch auf andere Buchsen im Fahrwerks- und Aggregatelagerungsbereich anwendbar.The Invention is not only for Engine mounts but also on other bushes in the chassis and assembly storage area applicable.
