Die Erfindung betrifft eine Vorrichtung zur Unterdrück mg von Drehschwingungen sowie von Biegeschwingungen rotierender Wellen, bei der die Schwungmasse koaxial zur Welle angeordnet ist und ein innenliegendes Befestigungselement, einen auSenlisgenders Schwunyring und zwischen dissen beiden angeordnete elastische Däispfungaelemerite aufweist, wobei Bämpfungselemente erster Art, die fest mit Befestigungselement und Schwungring verbunden sind und Dämpfungselemente zweiter Art, die nur mit dem Befestigungselement verbunden sind und vom Schwungring getrennt sind, vorgesehen sindThe invention relates to a device for suppressing torsional vibrations and bending vibrations of rotating shafts, in which the flywheel mass is arranged coaxially to the shaft and has an internal fastening element, an external flywheel ring and elastic damping elements arranged between the two, whereby damping elements of the first type, which are firmly connected to the fastening element and flywheel ring, and damping elements of the second type, which are only connected to the fastening element and are separate from the flywheel ring, are provided.
Gattungsgemäße Vorrichtungen sind bspw. in den DE-OS'en 33 34 393, 33 36 174 und 35 31 115 beschrieben. Sie dienen der Schwingungsdämpfung von rotierenden Wellen, indem sie bspw. auf ainc &igr; Wellenflansch befestigt werden. Bisher wurden sie über ein topfförmiges Befestigungselement, das Bohrungen zur Verschraubung des Befestigungselementes mit einem Wellenflansch od. dgl. aufwies, an einer Welle, bevorzugt einer Antriebswelle eines Kraftfahrzeugs, befestigt. Die Baulänge_ der bekannten Vorrichtungen war bisher durch die Länge des Befestigungselementes bestimmt. Ferner erforderte die Anbringung mittels Schrauben einenDevices of this type are described, for example, in DE-OS 33 34 393, 33 36 174 and 35 31 115. They serve to dampen vibrations in rotating shafts by being fastened, for example, to a shaft flange. Previously, they were fastened to a shaft, preferably a drive shaft of a motor vehicle, using a pot-shaped fastening element that had holes for screwing the fastening element to a shaft flange or the like. The overall length of the known devices was previously determined by the length of the fastening element. Furthermore, attachment using screws required a
f erheblichen Arbeltsaufwand, wie er insbesondere bei einer f considerable workload, which is particularly the case with a
&xgr; auf große Fertigungsmengen ausgerichteten Produktion, wie &xgr; production aimed at large production volumes, such as
h in der Kraftfahrzeugproduktion, unerwünscht ist. Während h in motor vehicle production, is undesirable. While
'(. eines Tiefziehprozesses mußten aufwendig Löcher in den '(. a deep drawing process required laborious holes to be drilled into the
' topfartigen Formling hineingestanzt werden. Nachteilig war' pot-shaped molding. The disadvantage was
auch, daß die bekannten Schwingungsdämpfer relativ viel Raum benötigten was bei bestimmten Anbringungsorten ihre Anwendung verhinderte.also that the known vibration dampers required a relatively large amount of space, which prevented their use in certain installation locations.
Es ist demzufolge Aufgabe der Erfindung, die oben angegebenen Nachteile der Schwingungsdämpfer nach dem Stand der Technik zu vermeiden.It is therefore an object of the invention to avoid the above-mentioned disadvantages of the vibration dampers according to the prior art.
Die Aufgabe wird erfindungsgesnäß gelöst, indem das Befestigungselement nicht über die Baulänge des Schwungrings hinausragt.The problem is solved according to the invention in that the fastening element does not protrude beyond the overall length of the flywheel ring.
Dabei ist es besonders vorteilhaft, wenn das Befestigungselement ein im wesentlichen ringförmiger Körpe" ist, dessen Innenausnehmvng im wesentlichen der Außenform eines Flansches der zu dämpfenden Welle entspricht.It is particularly advantageous if the fastening element is a substantially ring-shaped body, the inner recess of which essentially corresponds to the outer shape of a flange of the shaft to be dampened.
Dadurch, daß die Baulänge des Befestigungselementes herabgesetzt wird, ist es nunmehr möglich, den erfindungsgemäßen Schwingungsdämpfer auch in räumlich beengten Bereichen an Wellen einzusetzen.By reducing the overall length of the fastening element, it is now possible to use the vibration damper according to the invention even in spatially confined areas on shafts.
Dabei ist es besonders vorteilhaft, wenn das Befestigungselement als ringförmiger Körper ausgebildet ist und demzufolge über einen Längspreßsitz am Flansch einer Welle, ohne aufwendiges Festschrauben, ggf. auch über einen Toleranzring zwischen Befestigungselement-Innenwand und Flansch, befestigt werden kann. In allen Fällen entfällt daw aufwendige Festschrauben und es können erhebliche Kosten bei der Herstellung der Verbindung Welle/Schwingungffdämpfer, also der Montage, erzJ'jlt werden.It is particularly advantageous if the fastening element is designed as a ring-shaped body and can therefore be fastened to the flange of a shaft via a longitudinal press fit without complex screwing, if necessary also via a tolerance ring between the inner wall of the fastening element and the flange. In all cases, complex screwing is not necessary and considerable costs can be saved in producing the shaft/vibration damper connection, i.e. in assembly.
Insbesondere bei einer besonders bevorzugten Anwendung des erfindungsgemäßen Schwingungstilgers am Flansch dep Getriebeausgangs ergeben sich durch die erfindungsgemäße Ausgestaltung sowohl eine bessere Raumaufteilung in diesem Bereich als auch eine preiswertere Montage.In particular, in a particularly preferred application of the vibration damper according to the invention on the flange of the transmission output, the design according to the invention results in both a better spatial distribution in this area and a more cost-effective assembly.
Das als Ring ausgebildete Befestigungselement selbst ist wegen Entfallens der Bohrungen weniger aufwendig herstell bar.The fastening element itself, which is designed as a ring, is less complex to manufacture because there is no need for holes.
Nachfolgend soll die Erfindung anhand oiner bevorzugten Ausgestaltung der Erfindung unter !Jezugnahme auf die begleitende Zeichung näher erläutert werden. Dabei zeitt:The invention will be explained in more detail below using a preferred embodiment of the invention with reference to the accompanying drawing.

Tn Fig. 1 und 2 ist ein als Dämpfermasse wirkender Schwungring 1 über elastische Dämpfungselemente 3,4, an einem Befestigungsring 2 angekoppelt. Dabei sind Dämpfungselemente der ersten Art 3, die hier aus gummiartigem Material ausgebildet sind, an beiden Bauteilen bevorzugt durch Anvulkanisation, befer-*;igt, während Dämpfungselemente zweiter Art 4 am Befestigungsring befestigt sind, aber vom Schwungring 1 getrennt sind. Zwischen oeiden Dämpfungselementtypen 3,4 befinden sich Zwischenräume 5, in denen Kühlluft zirkulieren kann. Zwischen den Dämpfungselementen der zweiten Art 4 und der Schwungringinnenflächo ist ein Spalt 8 ausgebildet, dessen Dimensionen bevorzugt so gewählt sind, daB das dazugehörige Dämpfungseleinent 4 an der Schwungringinnenfläche anliegt.In Fig. 1 and 2, a flywheel 1 acting as a damper mass is coupled to a fastening ring 2 via elastic damping elements 3, 4. Damping elements of the first type 3, which are made of rubber-like material here, are attached to both components, preferably by vulcanization, while damping elements of the second type 4 are attached to the fastening ring but are separated from the flywheel 1. Between both types of damping elements 3, 4 there are gaps 5 in which cooling air can circulate. Between the damping elements of the second type 4 and the inner surface of the flywheel a gap 8 is formed, the dimensions of which are preferably selected so that the associated damping element 4 rests against the inner surface of the flywheel.
Der Befestigungsring liegt reibschlüssig über Längspreßsitz an der Außenfläche des Flansches 7 der Welle 8 an, wodurch die Verbindung zwischen dem Dämpfer und der zuThe fastening ring is frictionally engaged via a longitudinal press fit on the outer surface of the flange 7 of the shaft 8, whereby the connection between the damper and the
