Oberbegriff des Anspruchs 1.The
The invention relates to a torsional vibration damper according to
Preamble of

Energiespeicher werden auch, wie dies aus der
Derartige Drehschwingungsdämpfer finden beispielsweise Verwendung bei so genannten Zweimassenschwungrädern. Diese verfügen über ein so genanntes Primärblech als Eingangsteil für die erste Schwungmasse, wobei dieses Primärblech im Allgemeinen an die Kurbelwelle der Brennkraftmaschine angeschraubt oder auf sonstige Weise angebracht wird. Dieses Primärblech bildet dann zusammen mit weiteren Bauteilen die erste Schwungmasse, die den gehäuseartigen Abschnitt bildet, indem dann beispielsweise Schraubenfedern als Kraftspeicher aufgenommen sind. Dieses Primärblech hat eine kritische Biege-Eigenfrequenz. Dabei wirkt die Axialdynamik an der Kurbelwellenanschraubfläche als Anregungsmechanismus für das Primärblech. Diese Axialdynamik ergibt sich aus der Durchbiegung der Kurbelwelle infolge der Zündkräfte und Massenkräfte. Im Allgemeinen ist das Primärblech den gestellten Anforderungen gewachsen. Es gibt jedoch auch besonders kritische Anwendungen, bei denen beispielsweise im Stand der Technik entweder ein Schmiedeteil oder auch so genannte Flexplates zum Einsatz kommen. Diese Ausführungsformen haben jedoch Nachteile hinsichtlich der Kosten.such Torsional vibration dampers are used, for example in so-called dual-mass flywheels. These have a so-called primary sheet as input part for the first flywheel, with this primary plate in general bolted to the crankshaft of the engine or on other way is attached. This primary sheet forms then together with other components, the first flywheel, the forms the box-like section, then, for example Coil springs are added as energy storage. This primary sheet has a critical natural bending frequency. The axial dynamics act here at the Kurbelwellenanschraubfläche as an excitation mechanism for the primary sheet. This axial dynamics results resulting from the deflection of the crankshaft due to the ignition forces and mass forces. In general, the primary sheet is adapted to the requirements. But there are also special ones critical applications where, for example, in the prior art either a forging or so-called flexplates are used come. However, these embodiments have disadvantages in terms of costs.
Sofern diese Eigenfrequenzen innerhalb des Fahrbereichs oder nur unzureichend oberhalb zu liegen kommen, kann dies zu Schwingungsamplituden bzw. Materialspannungen an der Primärscheibe oder am Primärblech führen, die dieses nicht mehr lebensdauerfest ertragen kann.Provided these natural frequencies within the driving range or insufficient come to lie above, this can be to vibration amplitudes or Material stresses on the primary pulley or on the primary sheet lead them to endure this no longer life can.
Der vorliegenden Erfindung lag die Aufgabe zugrunde, Drehschwingungsdämpfer der eingangs beschriebenen Art zu schaffen, bei denen kritische Biegeschwingungen reduziert sind, und zwar möglichst in allen auftretenden Betriebsbedingungen. Auch soll gewährleistet sein, dass eine besonders einfache Montage sowie kostengünstige Herstellung von Drehschwingungsdämpfern möglich ist.Of the Present invention was based on the object, torsional vibration damper to create the type described above, in which critical bending vibrations are reduced, if possible in all occurring Operating conditions. It should also be ensured that a particularly simple installation and cost-effective production of Torsional vibration dampers is possible.
Gemäß der
Erfindung wird dies durch eine Anordnung gemäß insbesondere
dem kennzeichnenden Teil des Anspruchs 1 erzielt. Weitere Ausgestaltungen
und Vorteile der Erfindung ergeben sich aus den Unteransprüchen.According to the
This is achieved by an arrangement according to the invention in particular
achieved the characterizing part of
Der erfindungsgemäß angebrachte Tilger ist auf die kritische Biege-Eigenfrequenz des Primärblechs abgestimmt. Der Zweck dieses zusätzlich angebrachten Tilgers besteht nun darin, die Schwingungsamplituden der Primärscheibe zu reduzieren; die Schwingungsenergie wird sozusagen auf den Tilger umgeleitet.Of the According to the invention attached absorber is on the matched critical natural bending frequency of the primary sheet. The purpose of this additional attached Tilger is now in it, the vibration amplitudes of the primary disk to reduce; the vibrational energy is put on the absorber, so to speak diverted.
Für einen Tilger ist grundsätzlich eine federnd angebundene Masse notwendig. Als Masse sind verschiedene Möglichkeiten denkbar. Im einfachsten Fall kann zum Beispiel der im Normalfall vorhandene Zahnkranz für den Anlasser verwendet werden. Der Zahnkranz muss allerdings in Umfangsrichtung steif bzw. fest an die Primärscheibe angebunden sein, so dass er das Drehmoment des Anlassers auf die Primärseite des Zweimassenschwungrades übertragen kann. Axial zu dieser Richtung, also parallel zur Drehachse des Drehschwingungsdämpfers, wird der Zahnkranz mit einer definierten Steifigkeit angebunden. Dabei wird die Steifigkeit so gewählt, dass sich eine Tilgungsfrequenz einstellt, die der kritischen Biege-Eigenfrequenz entspricht. Zusätzlich kann dem Tilger eine Reib- bzw. Dämpfungseinrichtung überlagert werden. Diese Energiesenke kann notwendig sein, um die Amplituden der beiden sich ergebenden Nebenmaxima zu minimieren bzw. im Idealfall zu unterdrücken.For a Tilger is basically a springy tailed Mass necessary. As mass are different possibilities conceivable. In the simplest case, for example, the normally existing Sprocket used for the starter. The sprocket However, in the circumferential direction must be stiff or fixed to the primary pulley be tethered so that he puts the torque of the starter on the Transfer primary side of the dual mass flywheel can. Axial to this direction, ie parallel to the axis of rotation of Torsion damper, the sprocket with a defined Stiffness tethered. The stiffness is chosen that sets a repayment frequency, the critical natural bending frequency equivalent. In addition, the absorber a Reib- or Damping be superimposed. These Energy sink may be necessary to increase the amplitudes of the two themselves Minimize or ideally suppress resulting secondary maxima.
