Description
Die Erfindung betrifft einen Drehschwingungsdämpfer insbesondere für einen Antriebsstrang eines Kraftfahrzeugs mit einem um eine Drehachse verdrehbaren Eingangsteil und einem entgegen der Wirkung einer eingangsseitig beaufschlagten Federeinrichtung relativ verdrehbaren Ausgangsteil mit einem die Federeinrichtung ausgangsseitig mittels radial erweiterter Arme beaufschlagenden Flanschteil und einem mit dem Flanschteil verbundenen Nabenteil mit einer Innenverzahnung. Drehschwingungsdämpfer dienen insbesondere in Antriebssträngen von Kraftfahrzeugen mit einer Brennkraftmaschine zur Dämpfung von Drehschwingungen dieser, indem ein mit der Kurbelwelle der Brennkraftmaschine fest verbundenes Eingangsteil entgegen der Wirkung einer Federeinrichtung relativ gegenüber einem das anliegende Drehmoment auf ein nachfolgendes Aggregat, beispielsweise ein Getriebe, eine Doppelkupplung oder dergleichen übertragendes Ausgangsteil verdreht wird. Hierbei wird die Federeinrichtung während einer Drehmomentspitze komprimiert und gibt die dabei gespeicherte Energie in einem Drehmomenttal wieder an den Antriebsstrang ab, so dass insgesamt ein gleichmäßigerer Drehmomentverlauf nach dem Drehschwingungsdämpfer auftritt als vor diesem. Es hat sich hierbei zur Verbesserung einer Schwingungsisolation des Drehschwingungsdämpfers als besonders wirksam erwiesen, unter Ausbildung eines geteilten Schwungrads dem Eingangsteil eine Primärschwungmasse und dem Ausgangsteil eine Sekundärschwungmasse zuzuordnen. Hierbei können Bauteile wie Aggregate und dergleichen, beispielsweise Bauteile einer Reibungskupplung, einer Doppelkupplung, eines Drehmomentwandlers und dergleichen als Sekundärschwungmasse dienen.The invention relates to a torsional vibration damper, in particular for a drive train of a motor vehicle having a rotatable about an axis input part and a counter to the action of an input side acted spring device relatively rotatable output part with a spring means on the output side by means of radially extended arms acting on the flange part and a connected to the flange hub part with a internal gearing. Torsional vibration dampers are used in particular in drive trains of motor vehicles with an internal combustion engine for damping torsional vibrations of these by an integral with the crankshaft of the engine input part against the action of a spring device relative to an applied torque to a subsequent unit, such as a transmission, a double clutch or the like transmitting output part is rotated. In this case, the spring device is compressed during a torque peak and outputs the stored energy in a torque valley back to the drive train, so that a total of a more uniform torque curve after the torsional vibration occurs as before this. It has proven to be particularly effective for improving a vibration isolation of the torsional vibration damper, to assign the input part of a primary flywheel and the output part of a secondary flywheel to form a split flywheel. Here, components such as units and the like, for example components of a friction clutch, a dual clutch, a torque converter and the like can serve as a secondary flywheel.

Aufgabe der Erfindung ist die vorteilhafte Weiterbildung eines Drehschwingungsdämpfers und eines verbesserten Verfahrens zur Herstellung eines Drehschwingungsdämpfers. Insbesondere sollen die Montage erleichtert und die Herstellkosten gesenkt werden. The object of the invention is the advantageous development of a torsional vibration damper and an improved method for producing a torsional vibration damper. In particular, the assembly should be facilitated and the production costs are reduced.
Die Aufgabe wird durch die Vorrichtung des Anspruchs 1 und des Verfahrens des Anspruchs 6 gelöst. Die von dem Anspruch 1 abhängigen Ansprüche geben vorteilhafte Ausführungsformen der Vorrichtung wieder.The object is achieved by the device of claim 1 and the method of
Der vorgeschlagene Drehschwingungsdämpfer eignet sich insbesondere für einen Antriebsstrang eines Kraftfahrzeugs zur Schwingungsdämpfung einer Brennkraftmaschine dieses Antriebsstrangs. Der Drehschwingungsdämpfer enthält hierzu ein um eine Drehachse verdrehbares, beispielsweise aus einem ersten, von der Kurbelwelle der Brennkraftmaschine angetriebenen Scheibenteil und einem zweiten, mit dem ersten radial außen fest und dicht verbundenen zweiten Scheibenteil gebildetes Eingangsteil und ein entgegen der Wirkung einer in einem von den beiden Scheibenteilen gebildeten Ringraum aufgenommenen und von diesen eingangsseitig, beispielsweise mittels Anprägungen beaufschlagten Federeinrichtung relativ verdrehbares Ausgangsteil mit einem die Federeinrichtung ausgangsseitig beaufschlagenden Flanschteil und einem mit diesem verbundenen Nabenteil, wobei Flanschteil und Nabenteil einteilig als Scheibenteil ausgebildet sind. Hierdurch entfällt die Vernietung zwischen Nabenteil und Flanschteil. Desweiteren wird Montageaufwand gespart und ein Stanzausbruch des Flanschteils verringert.The proposed torsional vibration damper is particularly suitable for a drive train of a motor vehicle for vibration damping of an internal combustion engine of this drive train. The torsional vibration damper for this purpose includes a rotatable about an axis of rotation, for example, from a first, driven by the crankshaft of the internal combustion engine disc part and a second, with the first radially outside firmly and tightly connected second disc part formed input part and against the action of a in one of the two Disc parts formed annular space and received by these input side, for example, acted upon by embossing spring device relatively rotatable output part with a spring device on the output side acting flange and a connected thereto hub part, wherein flange and hub part are integrally formed as a disc part. This eliminates the riveting between hub part and flange. Furthermore, assembly costs are saved and a punching breakage of the flange part is reduced.
Das Scheibenteil weist radial außen radial erweiterte, in den Ringraum eingreifende Arme auf, die Energiespeicher der Federeinrichtung, beispielsweise Bogenfedern, gerade Schraubendruckfedern oder dergleichen stirnseitig in Zug- und/oder Schubrichtung eines Drehmomentflusses im Antriebsstrang beaufschlagen. Radial innen weist das Scheibenteil eine Innenverzahnung auf, welche beispielsweise an einem Innenumfang eines axial umgelegten Ansatzes des Scheibenteils vorgesehen sein kann. Die Innenverzahnung bildet einen Drehschluss gegenüber einer Welle, beispielsweise einer Getriebeeingangswelle, einem Wellenzapfen, beispielsweise einem Eingangsteil einer Doppelkupplung, einem Drehmomentwandler oder ähnlichen Aggregaten, oder dergleichen.The disk part has radially outward radially expanded, engaging in the annulus arms, the energy storage of the spring device, such as bow springs, helical compression springs or the like act on the front side in the tensile and / or thrust direction of a torque flow in the drive train. Radially inside the disk part has an internal toothing, which may be provided for example on an inner periphery of an axially folded-over approach of the disk part. The internal toothing forms a rotational connection with respect to a shaft, for example a transmission input shaft, a shaft journal, for example an input part of a double clutch, a torque converter or similar units, or the like.
Das Scheibenteil ist bevorzugt partiell unterschiedlich gehärtet. Beispielsweise kann das gesamte Scheibenteil zur Einstellung einer Härte der Innenverzahnung thermisch gehärtet, beispielsweise geglüht sein.The disk part is preferably partially hardened differently. For example, the entire disk part to set a hardness of the internal teeth can be thermally cured, for example, be annealed.
Die mechanisch stark belasteten Arme des Scheibenteils können zusätzlich induktiv gehärtet sein. The mechanically heavily loaded arms of the disc part may additionally be inductively hardened.
Das Scheibenteil kann vor dem Härten aus Blech beispielsweise mittels eines Stanz- und Umformverfahrens hergestellt sein. Das Scheibenteil kann abgesehen von der Räumung der Innenverzahnung werkzeugfallend hergestellt sein. The disc part may be made of sheet metal before curing, for example by means of a stamping and forming process. The disc part can be made tool falling apart from the clearance of the internal teeth.
Das vorgeschlagene Verfahren zur Herstellung des vorgeschlagenen Drehschwingungsdämpfers enthält ein Stanz- und Blechumformungsverfahren zur Herstellung des Scheibenteils aus Blech mit einem radial innen angeordneten axialen Ansatz sowie ein Härteverfahren, bei dem in einem ersten Härteschritt das Scheibenteil gehärtet wird, beispielsweise geglüht wird und in einem zweiten Härteschritt die Arme des Scheibenteils induktiv gehärtet werden. Weiterhin enthält das Verfahren ein Räumverfahren, bei dem die Innenverzahnung geräumt wird. Die Räumung der Innenverzahnung wird bevorzugt nach dem ersten und vor dem zweiten Härteschritt durchgeführt. Die Erfindung wird anhand des in der einzigen Figur dargestellten Ausführungsbeispiels näher erläutert. Diese zeigt einen Teilschnitt durch einen erfindungsgemäßen Drehschwingungsdämpfer. The proposed method for producing the proposed torsional vibration damper includes a stamping and Blechumformungsverfahren for producing the disc part made of sheet metal with a radially inner axial approach and a hardening process in which the disc part is cured in a first hardening step, for example, is annealed and in a second hardening step the arms of the disc part are inductively hardened. Furthermore, the method includes a clearing method in which the internal toothing is cleared. The evacuation of the internal toothing is preferably carried out after the first and before the second hardening step. The invention will be explained in more detail with reference to the embodiment shown in the single figure. This shows a partial section through a torsional vibration damper according to the invention.
