Description
Die Erfindung betrifft einen Batterie-Schwingungstilger nach dem Oberbegriff des Anspruchs 1.The The invention relates to a battery vibration absorber according to the preamble of claim 1.
Es ist bekannt, daß Fahrzeugkarosserien zu Schwingungen neigen, zu denen diese sowohl vom Fahrwerk als auch von der antreibenden Brennkraftmaschine angeregt werden und die von einem Fahrzeuginsassen als sehr unangenehm und damit komfortmindernd empfunden werden. Diesen Schwingungen wird durch eine entsprechende Auslegung von Aggregatlagern begegnet, aber auch durch Schwingungsenergie aufnehmende Zusatzmassen, die entweder im Vorder- oder im Hinterwagen elastisch befestigt werden. Diese Maßnahmen sind jedoch in ihrer Wirkung begrenzt, wegen des zusätzlichen Raumbedarfs nachteilig und wegen der Erhöhung des Fahrzeuggewichtes unerwünscht. Deshalb ist schon vorgeschlagen worden, im Fahrzeug vorhandene Massen als Schwingungstilger zu verwenden, insbesondere die Fahrzeugbatterie (Batterie) mit ihrem hohen Raumgewicht. Eine Lösung sieht vor, die Batterie an einer Aufnahme zu befestigen, vorzugsweise im Kofferraum, die an einer Seite um eine fahrzeugseitig horizontale Achse schwenkbar und an der gegenüberliegenden Seite vermittels eines Schwimmkörpers in einer Ölwanne schwimmend gelagert ist, so daß sich die Aufnahme mit der Batterie im wesentlichen in Z-Richtung, hydraulisch gedämpft, bewegen kann.It is known that vehicle bodies tend to oscillate to these from both the suspension and be stimulated by the driving internal combustion engine and the from a vehicle occupant as very unpleasant and thus comfort-reducing be felt. These vibrations are by a corresponding Design of unit bearings met, but also by vibration energy receiving additional masses, either in the front or in the rear be attached elastically. These measures are however in theirs Limited effect, because of the additional Space requirement disadvantageous and because of the increase in vehicle weight undesirable. Therefore, it has already been proposed in the vehicle existing masses to use as a vibration damper, in particular the vehicle battery (Battery) with its high density. One solution is to use the battery to attach to a receptacle, preferably in the trunk, the pivotable on one side about a vehicle-side horizontal axis and at the opposite Side by means of a float in an oil pan is floating, so that the recording with the battery essentially in the Z direction, hydraulically steamed, can move.

Es ist Aufgabe der Erfindung, einen Batterie-Schwingungstilger nach dem Oberbegriff des Anspruchs 1 so zu gestalten, daß insbesondere Torsionsschwingungen des Fahrzeugaufbaus reduziert werden.It is the object of the invention, a battery vibration absorber after to make the preamble of claim 1 so that in particular Torsionsschwingungen the vehicle body can be reduced.
Diese Aufgabe wird bei einem Batterie-Schwingungstilger nach dem Oberbegriff des Anspruch 1 durch dessen kennzeichnende Merkmale gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen aufgeführt.These Task is in a battery vibration absorber according to the preamble of claim 1 solved by its characterizing features. advantageous Embodiments are listed in the subclaims.
Die Erfindung besteht darin, daß bei einem Batterie-Schwingungstilger, bei dem die Batterie mit einer Aufnahmeeinrichtung für diese in einer fahrzeugfesten Halterung mit Entkopplungselementen aufgehängt ist, die jeweils zwischen zwei sich in der Z-Richtung erstreckenden Wandungsbereichen der Aufnahmeeinrichtung und der Halterung angeordnet sind, auf jeder Batterieseite ein Entkopplungselement angeordnet ist und jedes Entkopplungselement so gestaltet ist, daß es eine Bewegung der Aufnahmeeinrichtung gegenüber der Halterung in der Z-Richtung ermöglicht und quer zu dieser weitestgehend unterbindet. Damit ist ein Batterie-Schwingungstilger gegeben, der eine Relativbewegung der aus der Batterie und der Aufnahmeeinrichtung gebildeten Tilgermasse gegenüber dem Fahrzeugaufbau quer zur Z-Richtung verhindert und sich die Tilgermasse nur in dieser bewegen kann. Torsionsschwingungen des Fahrzeugaufbaus, wie sie insbesondere bei Cabrios auftreten, können damit erheblich reduziert werden. Dadurch, daß die Entkopplungselemente auf jeder Batterieseite vorgesehen sind, sind weitere Anschlag- oder Führungselemente entbehrlich.The Invention is that at a battery vibration absorber, in which the battery with a Recording device for this is suspended in a vehicle-mounted bracket with decoupling elements, each between two extending in the Z direction wall areas the receiving device and the holder are arranged on each Battery side a decoupling element is arranged and each decoupling element so it is designed that it a movement of the receiving device relative to the holder in the Z direction allows and across this largely prevented. This is a battery vibration absorber given a relative movement of the battery and the receiving device formed absorber mass opposite prevents the vehicle body transverse to the Z direction and the absorber mass only in this can move. Torsional vibrations of the vehicle body, as they occur especially in convertibles can thus significantly reduced become. In that the Decoupling elements are provided on each battery side are more Stop or guide elements dispensable.
Die Entkopplungselemente können so gestaltet sein, daß diese einen festen Rahmen zur Anordnung an der Halterung oder der Aufnahmeeinrichtung und ein zentral innerhalb des Rahmens angeordnetes Verbindungsmittel zur Anordnung an der jeweils anderen Komponente aufweisen. Zwischen dem Verbindungmittel und dem Rahmen sind in einer Richtung quer zur der Richtung, die im Fahrzeug in der Z-Richtung ausgerichtet ist, elastische Federmittel angeordnet. In einer bevorzugten Ausführungsform ist das Verbindungsmittel eine Aufnahmebuchse für einen an einer der beiden Komponenten, vorzugsweise der Aufnahmeeinrichtung für die Batterie, angeordneten Lagerzapfen. Der Rahmen und das Verbindungsmittel sind vorteilhaft aus Aluminium gefertigt, um den elastischen Federmitteln jeweils ein stabiles Widerlager und dem Entkopplungselement die nötige Festigkeit zur Übertragung von Schwingungsenergie bei Geringhaltung seines Eigengewichtes zu geben.The decoupling elements can be designed so that they have a fixed frame for placement on the holder or the receiving device and a centrally disposed within the frame connecting means for arrangement on the other component. Between the connecting means and the frame are in a direction transverse to the direction in the vehicle in the Z-direction is aligned, elastic spring means arranged. In a preferred embodiment, the connecting means is a receiving socket for a on one of the two components, preferably the receiving device for the battery, arranged bearing journals. The frame and the connecting means are advantageously made of aluminum to give the elastic spring means each a stable abutment and the decoupling element the necessary strength for the transmission of vibration energy while keeping its own weight.
Als elastische Federmittel können quer zur vorgesehenen Z-Richtung zwei speichenartige, um 180° an dem Verbindungsmittel versetzt angeordnete Elemente aus einem elastischen Material eingesetzt sein, wobei die vorzugsweise aus Gummi bestehenden Elemente mit dem Rahmen und dem Verbindungsmittel stoffschlüssig verbunden sind, insbesondere anvulkanisiert sind.When elastic spring means can transverse to the intended Z-direction two spoke-like, by 180 ° to the connecting means offset elements arranged to be used from an elastic material, wherein the elements preferably made of rubber with the frame and the connecting means are materially connected, in particular vulcanized.
Zur Verhinderung einer übermäßigen Bewegung des Verbindungsmittels in Z-Richtung sind am Rahmen zwei eine solche Bewegung begrenzende elastische Anschlagelemente, insbesondere aus einem stark energieabsorbierenden Material, angeordnet. Diese sind am Rahmen ebenfalls anvulkanisiert.to Prevent excessive movement of the connecting means in the Z direction are on the frame two such Motion limiting elastic stop elements, in particular a highly energy absorbing material. These are also vulcanised on the frame.
Damit auf jeder Batterieseite ein Entkopplungselement angeordnet sein kann, haben die Aufnahmeeinrichtung und die Halterung die Form einer rechteckigen Wanne. Bevorzugt sind die Entkopplungselemente zwischen diesen beiden Wannen an wenigstens zwei gegenüberliegenden Wandungspaaren außermittig, und zwar im gleichen Uhrzeigersinn versetzt, angeordnet. Auf diese Weise wird eine größere Dämpfungs- und Führungswirkung quer zur Z-Richtung erzielt. Bevorzugt sind die Entkopplungselemente in derselben X-Y-Ebene, insbesondere im wesentlichen in der Schwerpunktebene der aus der Aufnahmeeinrichtung und der Batterie gebildeten Tilgermasse, angeordnet.In order to be arranged on each battery side a decoupling element can, the receiving device and the holder have the shape of a rectangular Tub. Preferably, the decoupling elements between these two Tubs on at least two opposite Wall pairs off-center, namely offset in the same clockwise direction, arranged. To this Way is a greater damping and leadership achieved across the Z direction. The decoupling elements are preferred in the same X-Y plane, in particular essentially in the focal plane the absorber mass formed from the receiving device and the battery, arranged.
