Zweikammer-Motorlager werden zur Schwingungsdämpfung des Motors in Kraftfahrzeugen verwendet. Die vom Motor verursachten Schwingungen werden hierbei durch die Schwingungen der Flüssigkeitssäule im Überströmkanal gedämpft, der die Arbeitskammer und die Ausgleichskammer verbindet.Two-chamber engine mount are used to dampen vibrations of the engine used in motor vehicles. The caused by the engine Vibrations are damped by the vibrations of the liquid column in the overflow channel, which the Working chamber and the compensation chamber connects.
Ein
solches Motorlager ist aus der
Aufgabe ist es deshalb ein Zweikammer-Motorlager anzugeben, welches eine niedrige Bauhöhe aufweist und gleichzeitig in seinem Dämpfungsverhalten schaltbar ausgebildet ist.task it is therefore necessary to specify a two-chamber engine mount, which one has a low overall height and at the same time in its damping behavior is switchable.
Diese Aufgabe wird bei einem Zweikammer-Motorlager der eingangs genannten Art dadurch gelöst, dass in der Bodenplatte eine die Arbeitskammer begrenzende Entkopplungsmembran angeordnet ist, der eine Schalteinrichtung zugeordnet ist.This The task is the one mentioned in a two-chamber engine mount Kind of solved by that a decoupling membrane delimiting the working chamber in the base plate is arranged, which is assigned a switching device.
Durch die Anordnung der Entkopplungsmembran in der Bodenplatte der Arbeitskammer mit einer zugeordneten Schalteinrichtung wird es ermöglicht, das Zweikammer-Motorlager in seinem Dämpfungsverhalten zu verändern. Die in der Bodenplatte angeordnete Entkopplungsmembran ist von aussen gut zugänglich, so dass keine aufwendigen konstruktiven Massnahmen zur Schaltbarkeit der Entkopplungsmembran vorgenommen werden müssen. Die Entkopplungsmembran ist randseitig in der Bodenplatte fixiert und abgedichtet, so dass die hydraulische Flüssigkeit nicht aus der Arbeitskammer austreten kann. Die Entkopplungsmembran ist als elastische Gummimembran ausgebildet und in einem Entkopplungskäfig angeordnet. Dieser Entkopplungskäfig begrenzt die Arbeitskammer auf der Seite der Bodenplatte und weist an der zur Arbeitskammer zugewandten Seite Öffnungen auf, durch die die hydraulische Flüssigkeit hindurchströmen kann. Auf der zum Bodengehäuse zugewandten Seite sind ebenfalls Öffnungen angeordnet, die ein Austreten der verdrängten Luft und somit eine Bewegung der Entkopplungsmembran ermöglichen. Durch diese Anordnung wird ein Schalten der Entkopplungsmembran in dem Entkopplungskäfig zwischen wenigstens zwei Positionen ermöglicht. In einer ersten Position ist die Entkopplungsmembran frei beweglich, wobei sich die Entkopplungsmembran typischerweise während des Fahrbetriebes in dieser frei beweglichen Position befindet. Hochfrequente Schwingungen mit kleiner Amplitude werden von der Entkopplungsmembran aufgenommen. Bei grösseren Amplituden, wie sie beispielsweise im Leerlaufbetrieb auftreten, legt sich die Entkopplungsmembran an die Käfigwand an, wodurch eine hydraulische Dämpfung erzeugt wird.By the arrangement of the decoupling membrane in the base plate of the working chamber with an associated switching device it is possible to to change the damping behavior of the two-chamber engine mount. The Decoupling membrane arranged in the base plate is good from the outside accessible, so that no complex constructive measures for switchability the decoupling membrane must be made. The decoupling membrane is fixed and sealed at the edge in the base plate, so that the hydraulic fluid cannot leave the Chamber of Labor. The decoupling membrane is designed as an elastic rubber membrane and arranged in a decoupling cage. This decoupling cage delimits the working chamber on the side of the base plate and points openings on the side facing the working chamber through which the hydraulic fluid flow through can. On the to the floor case facing side are also openings that a Leak of the repressed Air and thus allow movement of the decoupling membrane. This arrangement enables switching of the decoupling membrane in the decoupling cage enabled between at least two positions. In a first position the decoupling membrane is freely movable, whereby the decoupling membrane typically during the driving operation is in this freely movable position. High-frequency vibrations with small amplitude are from the Decoupling membrane added. With larger amplitudes, like them occur, for example, in idle mode, the decoupling membrane lays down to the cage wall which creates hydraulic damping is produced.
Es lässt sich somit ein Zweikammer-Motorlager realisieren, welches aufgrund der Anordnung der Arbeits- und Ausgleichskammer auf gleicher Höhe eine niedrige Bauhöhe aufweist und darüber hinaus durch die erfindungsgemässe Anordnung der Entkopplungsmembran in seinem Dämpfungsverhalten in einfacher Weise schaltbar ausgebildet ist.It let yourself thus realize a two-chamber engine mount, which due to the Arrangement of the work and compensation chamber at the same level low height has and above through the inventive Arrangement of the decoupling membrane in its damping behavior in simple Is designed switchable.
In einer vorteilhaften Ausgestaltung der Erfindung ist die Schalteinrichtung als Luftkammer ausgebildet, die durch ein Bodengehäuse begrenzt ist. Das Bodengehäuse ist unterhalb des Gehäuses des Motorlagers angeordnet und begrenzt die Luftkammer. Durch Erzeugen eines Unterdrucks oder eines Vakuums in dieser Luftkammer kann die Entkopplungsmembran aus ihrer freibeweglichen Position heraus in die blockierte Position in Richtung der Luftkammer bewegt werden, so dass sie auf dem Boden des Entkopplungskäfigs anliegt und sie somit in ihrer Beweglichkeit blockiert ist.In An advantageous embodiment of the invention is the switching device formed as an air chamber bounded by a floor case is. The bottom case is below the case of the engine mount and limits the air chamber. By creating a negative pressure or a vacuum in this air chamber can Decoupling membrane from its free moving position in the blocked position is moved towards the air chamber, so that it rests on the bottom of the decoupling cage and therefore it is blocked in their mobility.
Dieses Bodengehäuse weist vorteilhaft einen Vakuumanschluss auf, an den ein Unterdruck oder eine Vakuumpumpe anschliessbar sind.This floor housing advantageously has a vacuum connection to which a vacuum or a vacuum pump can be connected.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist die Schalteinrichtung als elektromagnetische Spulenvorrichtung ausgebildet, die mit einer magnetisierbaren Entkopplungsmembran zusammenwirkt. In dieser Ausführungsform ist unterhalb des Entkopplungskäfigs eine elektromagnetische Spulenvorrichtung angeordnet, die mittels eines elektrischen Signals ansteuerbar ist. Um die Entkopplungsmembran mit der elektromagnetischen Spulenvorrichtung zu schalten, ist die Entkopplungsmembran magnetisierbar ausgebildet. Dazu kann die Entkopplungsmembran beispielsweise metalli sche Einlagen aufweisen, die dann mit dem Magnetfeld der elektromagnetischen Spulenvorrichtung zusammenwirken und eine Veränderung der Position der Entkopplungsmembran in dem Entkopplungskäfig bewirken. Die elektromagnetische Schalteinrichtung lässt sich besonders Platz sparend realisieren.In Another advantageous embodiment of the invention is Switching device designed as an electromagnetic coil device, which interacts with a magnetizable decoupling membrane. In this embodiment is below the decoupling cage an electromagnetic coil device arranged by means of an electrical signal can be controlled.

This can be done using the decoupling membrane for example, metallic deposits, which then with the Interact magnetic field of the electromagnetic coil device and a change the position of the decoupling membrane in the decoupling cage. The electromagnetic switching device can be particularly space-saving realize.
Bei einer weiteren vorteilhaften Ausgestaltung der Erfindung ist die Schalteinrichtung als eine ansteuerbare Zugvorrichtung ausgebildet, die an der Entkopplungsmembran angelenkt ist. Dazu ist vorteilhafterweise an der Entkopplungsmembran ein Zugband angelenkt, welches über eine Umlenknase geführt wird und von einem Stellglied betätigt wird. Dieses Stellglied kann elektrisch oder elektromagnetisch ausgebildet sein und ist ausserhalb des Gehäuses des Motorlagers angeordnet. Diese Ausführungsform benötigt ebenfalls wenig Platz und lässt sich je nach Ausgestaltung des Stellgliedes auch ohne elektrische Hilfsenergie realisieren.at Another advantageous embodiment of the invention is Switching device designed as a controllable pulling device, which is hinged to the decoupling membrane. This is advantageous on the decoupling membrane a drawstring articulated, which over a Deflection led is and is actuated by an actuator. This actuator can be electrical or electromagnetic outside the case arranged the engine mount. This embodiment also requires little space and can be depending on the design of the actuator, also without electrical auxiliary energy realize.
