Abstract
Description
Die Erfindung betrifft ein Zweimassenschwungrad zum Kompensieren von Drehstößen oder Drehmomentschwankungen einer Brennkraftmaschine nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a dual mass flywheel for compensating Turns or Torque fluctuations of an internal combustion engine according to the preamble of claim 1
Ein
Zweimassenschwungrad nach dem Stand der Technik ist beispielsweise
aus der deutschen Patentschrift
Die Dämpfungseinrichtung besteht üblicherweise aus in Umfangsrichtung wirksamen Kraftspeichern, die mit einer Verdrehung zwischen den Schwungmassen beaufschlagt werden. Primär- und Sekundärseite sind relativ zueinander über eine Lagerung verdrehbar gelagert, wobei die Lagerung üblicherweise ein Axial- und ein Radiallager aufweist. Bei dem Axiallager handelt es sich beispielsweise um ein Kugellager, bei dem im axialen Abstand dazu angeordneten Radiallager üblicherweise um ein Gleit- oder Wälzlager.The attenuator usually exists from circumferentially effective energy storage, with a twist be applied between the flywheel masses. Primary and secondary side are relative to each other a storage rotatably mounted, the storage usually has an axial and a radial bearing. In the thrust bearing acts For example, it is a ball bearing, in which at an axial distance arranged radial bearings usually around a sliding or roller bearing.
Derartige Zweimassenschwungräder, nachstehend ZMS genannt, haben den Nachteil, dass Taumelbewegungen und von der Kurbelwelle der Brennkraftmaschine auf die Primärseite einwirkende Axialschwingungen über Axial- und Radiallager auf die Sekundärseite, somit auch auf die Druckplatte einer integrierten Trockenkupplung und damit auf das gesamte Kupplungsausrücksystem übertragen werden. Beim Betätigen der Kupplung machen sich diese Bewegungen und Schwingungen im Fuß des Fahrers unangenehm als sogenanntes „Kupplungsbitzeln" bemerkbar.such Dual mass flywheels, hereafter referred to as ZMS, have the disadvantage that tumbling movements and from the crankshaft of the internal combustion engine acting on the primary side axial vibrations via axial and radial bearings on the secondary side, thus also on the pressure plate of an integrated dry clutch and thus transferred to the entire clutch release system. When pressing the Clutch make these movements and vibrations in the driver's foot uncomfortable as so-called "Kupplungsbitzeln" noticeable.
Der Erfindung liegt die Aufgabe zugrunde, ein Zweimassenschwungrad so zu gestalten, dass störende Schwingungen und Bewegungen verringert oder beseitigt werden.Of the Invention is based on the object, a dual mass flywheel so to make that disturbing Vibrations and movements are reduced or eliminated.
Gelöst wird diese Aufgabe durch eine Anordnung mit den im Anspruch 1 angegebenen Merkmalen.Is solved this object by an arrangement with the specified in claim 1 Features.
Beim Gegenstand des Anspruchs 1 sind bei einem Zweimassenschwungrad zum Kompensieren von Drehstößen oder Drehmomentschwankungen einer Brennkraftmaschine zwei koaxial zueinander angeordnete, entgegen der Wirkung einer Dämpfungseinrichtung gegeneinander verstellbar gelagerte Schwungmassen (Primärseite, Sekundärseite) vorhanden und die zwei Schwungmassen mittels einer ersten Lagerung relativ zueinander um eine Achse verdrehbar gelagert.At the The subject of claim 1 are in a dual mass flywheel for Compensating for torsional impacts or Torque variations of an internal combustion engine two coaxial with each other arranged, against the action of a damping device against each other adjustably mounted flywheels (primary side, secondary side) present and the two flywheel masses by means of a first storage mounted rotatable relative to each other about an axis.
Erfindungsgemäß wird vorgeschlagen, dass eine Lagerung ein Verschwenken der mindestens zwei Schwungmassen relativ zueinander quer zur (Dreh-) Achse ermöglicht. Durch die Verschwenkbarkeit der beiden Schwungmassen relativ zueinander ist gewährleistet, dass Taumelschwingungen der Primärseite des Zweimassenschwungrades nicht mehr in Form von unangenehmen Schwingungen/Vibrationen auf die Sekundärseite, danach auf den Kupplungsausrückmechanismus und zuletzt auf den Fuß des Fahrers übertragen werden. Somit wird erfindungsgemäß dem Zweimassenschwungrad ein weiterer Freiheitsgrad zugefügt, so dass in Richtung dieses Freiheitsgrades wirkende Anregungen verringert oder gar nicht übertragen werden.According to the invention, it is proposed that a bearing pivoting the at least two centrifugal masses relative to each other across the (rotational) axis allows. By the pivoting the two momentum masses relative to each other is ensured that tumbling vibrations of the primary side of the dual mass flywheel no longer in the form of unpleasant vibrations on the secondary side, then on the clutch release mechanism and last at the foot of the Driver's transfer become. Thus, according to the invention the dual mass flywheel added another degree of freedom, so that in the direction of this degree of freedom acting suggestions reduced or not transferred at all become.
Eine besonders bevorzugte Ausgestaltung der Vorrichtung ergibt sich, wenn eine einzige Lagerung die Verdrehbarkeit um die Achse sowie die Verschwenkbarkeit zur Achse gewährleistet. Somit entfällt der bei der Montage des Zweimassenschwungrades der durch den Einbau von zwei getrennten Lagern erhöhte Arbeits- und Materialaufwand. Im Betrieb verringern sich unter Umständen durch die Verwendung eines einzigen Lagers die Reibungsverluste.A particularly preferred embodiment of the device results, if a single bearing rotatability around the axis as well Ensures the pivotability to the axis. Thus eliminates the during assembly of the dual mass flywheel by the installation increased from two separate warehouses Labor and material costs. In operation may reduce by the use of a single bearing the friction losses.
Eine vorteilhafte Ausführung der Erfindung ist weiterhin dadurch gekennzeichnet, dass es sich bei der Lagerung um ein winkeleinstellbares Wälzlager, um ein Radial-Gelenklager oder um ein Gleitlager handelt und dass die Primärseite bzw. die Sekundärseite einen zylindrischen Fortsatz aufweist, an dem sich der Innen- oder Außenring des Wälz-, Gleit- oder Radial-Gelenklagers abstützt. Derartige Lager sind als Normteile erhältlich, so dass keine Sonderanfertigungen notwendig sind und somit Herstellkosten eingespart werden.A advantageous embodiment The invention is further characterized in that it is at the bearing around a angularly adjustable rolling bearing to a radial spherical plain bearings or is a plain bearing and that the primary side or the secondary side one having cylindrical extension, on which the inner or outer ring of rolling, Sliding or radial spherical plain bearings supported. Such bearings are available as standard parts, so no custom-made are necessary and thus manufacturing costs are saved.
Hierbei ist der Abkoppelgrad eines Gleitlagers gegen axiale Schwingungen und Taumelbewegungen unter axialer Vorlast der Kupplung besser als bei einem (Schrägrillen-) Kugellager, da das radiale Spiel trotz der eingeleiteten Vorlast im Gleitlager erhalten bleibt und minimierend auf eine Schwingungsneigung wirkt.in this connection is the Abkoppelgrad a sliding bearing against axial vibrations and wobbling under axial preload of the clutch better than a (oblique barbecue) Ball bearing, since the radial play despite the preload introduced remains in the plain bearing and minimizing vibration tendency acts.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in weiteren Ansprüchen, der Beschreibung und/oder den Figuren angegeben.Further advantageous embodiments of the invention are in further claims, the Description and / or the figures indicated.
Die Erfindung wird nun anhand eines Ausführungsbeispiels unter Zuhilfenahme der Zeichnung erläutert.The Invention will now be described with reference to an embodiment with the aid explained the drawing.
Dabei zeigen:there demonstrate:
Die Erfindung eignet sich insbesondere für ein Zweimassenschwungrad zum Kompensieren von Drehstößen oder Drehmomentschwankungen einer Brennkraftmaschine.The Invention is particularly suitable for a dual mass flywheel to compensate for torsional impacts or Torque fluctuations of an internal combustion engine.
