Description
Die Erfindung betrifft einen hydrodynamischen Drehmomentwandler mit den Merkmalen gemäß dem Oberbegriff von Anspruch 1.The invention relates to a hydrodynamic torque converter having the features according to the preamble of claim 1.
Aus der
Aufgabe der Erfindung ist es, die Drehschwingungsdämpfung eines hydrodynamischen Drehmomentwandlers zu verbessern.The object of the invention is to improve the torsional vibration damping of a hydrodynamic torque converter.
Erfindungsgemäß wird diese Aufgabe durch einen hydrodynamischen Drehmomentwandler mit den Merkmalen gemäß Anspruch 1 gelöst.According to the invention this object is achieved by a hydrodynamic torque converter with the features of claim 1.
Entsprechend wird ein hydrodynamischer Drehmomentwandler mit einem Turbinenrad und einem Drehschwingungsdämpfer mit einem ersten Energiespeicherelement einer ersten Dämpferstufe und einem zweiten Energiespeicherelement einer zweiten Dämpferstufe und einem die erste und zweite Dämpferstufe verbindenden Dämpferzwischenteil vorgeschlagen wobei das Turbinenrad über die Wirkung eines dritten Energiespeicherelements gegenüber dem Dämpferzwischenteil verdrehbar ist und dem Turbinenrad eine Zusatzmasse zugeordnet ist. Dadurch kann eine höhere Trägheitsmasse unter Einbeziehung der Masse des Turbinenrads erzielt werden und womit sich eine bessere Tilgerwirkung über die dritten Energiespeicherelemente erreichen lässt. Die Zusatzmasse kann mittelbar oder unmittelbar an dem Turbinenrad befestigt sein. So kann die Zusatzmasse an einem Bauteil des Turbinenrads, insbesondere an der Turbinenschale und/oder der Turbinennabe angebracht sein. Auch kann die Zusatzmasse zu dem Turbinenrad beabstandet angeordnet sein.Accordingly, a hydrodynamic torque converter with a turbine wheel and a torsional vibration damper with a first energy storage element of a first damper stage and a second energy storage element of a second damper stage and the first and second damper stage connecting damper intermediate part is proposed wherein the turbine wheel via the action of a third energy storage element with respect to the damper intermediate part is rotatable and the turbine wheel is assigned an additional mass. As a result, a higher inertial mass can be achieved with the involvement of the mass of the turbine wheel and with which a better damping effect can be achieved via the third energy storage elements. The additional mass may be attached directly or indirectly to the turbine wheel. Thus, the additional mass may be attached to a component of the turbine wheel, in particular to the turbine shell and / or the turbine hub. Also, the additional mass may be arranged spaced from the turbine wheel.
Insgesamt weist der Drehschwingungsdämpfer wenigstens zwei Dämpferstufen auf, kann aber auch mehrere in Reihe und/oder parallel wirksam verschaltete Dämpferstufen aufweisen, wobei die dritten Energiespeicherelemente mit einem oder auch mit mehreren der zwischen den einzelnen Dämpferstufen wirksamen Zwischenteile zusammen wirken kann.Overall, the torsional vibration damper on at least two damper stages, but may also have several in series and / or parallel effectively interconnected damper stages, the third energy storage elements can cooperate with one or more of the effective between the individual damper stages intermediate parts.
In einer bevorzugten Ausführung der Erfindung erfolgt die Beaufschlagung des dritten Energiespeicherelements durch ein an dem Turbinenrad drehfest angeordnetes Tilgerelement und die Zusatzmasse ist an dem Tilgerelement befestigt. Vorteilhafterweise ist die Zusatzmasse in einem radial äußeren Bereich des Tilgerelements befestigt. Vorzugsweise ist die Zusatzmasse drehfest gegenüber dem Tilgerelement, kann aber auch gegenüber dem Tilgerelement verschwenkbar sein. In letzterem Fall kann die Zusatzmasse beispielsweise als Fliehkraftpendelmasse ausgebildet sein, die gegenüber dem Tilgerelement entlang einer Pendelbahn verschwenkbar ist und an dem Tilgerelement mit Hilfe von Laufrollen aufgenommen ist.In a preferred embodiment of the invention, the loading of the third energy storage element is effected by a Tilgerelement rotatably mounted on the turbine wheel and the additional mass is attached to the Tilgerelement. Advantageously, the additional mass is fixed in a radially outer region of the absorber element. Preferably, the additional mass is rotationally fixed relative to the absorber element, but may also be pivotable relative to the absorber element. In the latter case, the additional mass may be formed, for example, as centrifugal pendulum mass, which is pivotable relative to the absorber element along a pendulum track and is accommodated on the absorber element by means of rollers.
In einer weiteren Ausgestaltung der Erfindung weist das Tilgerelement einen das dritte Energiespeicherelement radial außen umgreifenden Aufnahmebereich auf.In a further embodiment of the invention, the absorber element on a third energy storage element radially outermost encompassing receiving area.
In vorteilhafter Ausgestaltung der Erfindung ist die Zusatzmasse mit dem Tilgerelement vernietet. Auch kann die Zusatzmasse mit Hilfe einer anderen Befestigungsmöglichkeit an dem Tilgerelement angeordnet sein, beispielsweise verschraubt, verschweißt oder mit Abstandsbolzen verbunden sein.In an advantageous embodiment of the invention, the additional mass is riveted to the absorber element. Also, the additional mass can be arranged with the aid of another mounting option on the Tilgerelement, for example screwed, welded or connected to standoffs.
In einer weiteren Ausbildung der Erfindung weist die Zusatzmasse einer der Geometrie wenigstens eines benachbarten Teils angepasste Form auf. Damit wird insbesondere eine platzsparende Bauweise bei zugleich möglichst hoher Massenwirkung ermöglicht.In a further embodiment of the invention, the additional mass of a geometry of at least one adjacent part adapted shape. This allows in particular a space-saving design with at the same time the highest possible mass effect.
In einer vorteilhaften Ausführungsform der Erfindung ist das Tilgerelement axial zwischen Drehschwingungsdämpfer und Turbinenrad angeordnet ist. Auch kann das Tilgerelement auf einer Turbinennabe des Turbinenrads aufgenommen sein.In an advantageous embodiment of the invention, the absorber element is arranged axially between the torsional vibration damper and the turbine wheel. Also, the Tilgerelement can be accommodated on a turbine hub of the turbine wheel.
In einer weiteren Ausgestaltung der Erfindung überlappen sich die dritten Energiespeicherelemente mit den ersten und/oder zweiten Energiespeicherelementen radial. Damit kann eine gute Dämpfungswirkung und Tilgerwirkung erzielt werden.In a further embodiment of the invention, the third energy storage elements overlap radially with the first and / or second energy storage elements. Thus, a good damping effect and Tilgerwirkung can be achieved.
