Abstract
Description
Die Erfindung betrifft einen Drehschwingungsdämpfer zur Anordnung an einer Kurbelwelle eines Motors eines Kraftwagens.The The invention relates to a torsional vibration damper for arrangement on a crankshaft of an engine of a motor vehicle.
Kurbelwellen
von Motoren dienen zum Erzeugen eines Drehmoments aus den mittels
der Pleuelstangen übertragenen Kräften. Da die
Pleuelstangen bei jedem Kolbenhub beschleunigt und verzögert
werden, treten an der Kurbelwelle Drehschwingungen mit hohen Momenten
auf. Erfolgen die Drehschwingungen im Bereich einer Eigenfrequenz der
Kurbelwelle, kann diese beschädigt werden oder brechen.
Um die während des Betriebs auftretenden Drehschwingungen
zu reduzieren, werden sogenannte Drehschwingungsdämpfer
an der Kurbelwelle befestigt. Ein derartiger Drehschwingungsdämpfer
ist dabei beispielsweise bereits aus der
Als nachteilig an dem bekannten Drehschwingungsdämpfer ist dabei der Umstand anzusehen, dass dieser konstruktiv aufwändig ausgebildet sein muss, um die erforderliche Dichtigkeit zu besitzen. Dies führt zu erhöhten Produktionskosten.When is disadvantageous to the known torsional vibration damper to look at the fact that this is structurally complex must be designed to have the required tightness. This leads to increased production costs.
Aufgabe der vorliegenden Erfindung ist es daher, einen Drehschwingungsdämpfer der eingangs genannten Art zu schaffen, welcher einfacher und kostengünstiger herstellbar ist.task Therefore, it is the object of the present invention to provide a torsional vibration damper to create the type mentioned, which is easier and cheaper can be produced.
Die Aufgabe wird erfindungsgemäß durch einen Drehschwingungsdämpfer mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.The The object is achieved by a torsional vibration damper solved with the features of claim 1. advantageous Embodiments with appropriate and non-trivial Further developments of the invention are in the subclaims specified.
Ein einfacher und kostengünstiger herstellbarer Drehschwingungsdämpfer ist erfindungsgemäß dadurch geschaffen, dass ein an der Kurbelwelle festlegbares Trägerteil und wenigstens ein als Schwungmasse dienendes Außenteil vorgesehen sind, welche relativ zueinander bewegbar sind und zur Schwingungsdämpfung mittels zumindest einem aus einem Elastomer gefertigten Dämpfungselement miteinander in Wirkverbindung stehen. Mit anderen Worten ist es beim erfindungsgemäßen Drehschwingungsdämpfer nicht erforderlich, eine konstruktiv aufwändige, fluiddichte Arbeitskammer bereitzustellen. Statt dessen wird die Dämpfung und Tilgung auftretender Drehschwingungen mit Hilfe des kostengünstig aus einem Elastomer gefertigten Dämpfungselements bewerkstelligt. Das als Schwungmasse dienende Außenteil ermöglicht zudem eine besonders bauraumsparende Ausgestaltung des Drehschwingungsdämpfers, da neben der Funktion der Drehschwingungsdämpfung auch die Funktion des Schwungmassenausgleichs im Bauraum einer Kurbelwange realisiert werden.One simple and inexpensive to produce torsional vibration damper is inventively created by a fixable on the crankshaft carrier part and at least a serving as a flywheel outer part are provided which are movable relative to each other and for vibration damping by means of at least one made of an elastomer damping element with each other in operative connection. In other words, it is the invention Torsional vibration damper not required, a constructive to provide elaborate, fluid-tight working chamber. Instead of this is the damping and eradication occurring torsional vibrations with the help of the cost-effectively made of an elastomer Damper accomplished. That as a flywheel Serving outer part also allows a particularly space-saving Embodiment of the torsional vibration, because in addition to the Function of the torsional vibration damping also the function realized the inertia balance in the space of a crank arm become.
