Abstract
Die Erfindung betrifft einen Torsionsschwingungsdämpfer mit Federfenstern (1), dadurch gekennzeichnet, dass die Federfenster (1) durch Entspannungsbohrungen (2) erweitert sind.The invention relates to a torsional vibration damper with spring windows (1), characterized in that the spring windows (1) by expansion bores (2) are extended.
Description
Die Erfindung betrifft einen Torsionsschwingungsdämpfer mit spannungsoptimierten Federfenstern.The invention relates to a torsional vibration damper with voltage-optimized spring windows.
Aus dem Stand der Technik sind Torsionsschwingungsdämpfer mit Federfenstern seit langem bekannt. Im Betrieb eines Torsionsschwingungsdämpfers entstehen die größten Spannungen infolge Belastungen an den Fensterecken der Federfenster. Hieraus ergibt sich eine begrenzte Belastbarkeit des Torsionsschwingungsdämpfers.Torsional vibration damper with spring windows have long been known from the prior art. During operation of a torsional vibration damper, the greatest stresses arise as a result of loads on the window corners of the spring windows. This results in a limited load capacity of the torsional vibration damper.
Es besteht somit die technische Aufgabe die Nachteile aus dem Stand der Technik zu überwinden.It is therefore the technical task to overcome the disadvantages of the prior art.
Die Aufgabe wird erfindungsgemäß insbesondere gelöst durch einen Torsionsschwingungsdämpfer mit Federfenstern, wobei die Federfenster durch Entspannungsbohrungen erweitert sind.The object is achieved in particular by a torsional vibration damper with spring windows, wherein the spring windows are expanded by expansion holes.
Vorzugsweise sind die Entspannungsbohrungen Entspannungsvertiefungen, Aussparungen oder Ausnehmungen. Bevorzugt weisen die Federfenster eine durch die Entspannungsbohrungen vergrößerte Mantelfläche auf.Preferably, the expansion holes are depressions, recesses or recesses. The spring windows preferably have a lateral surface which is enlarged by the expansion bores.
Vorzugsweise weisen Komponenten des Torsionsschwingungsdämpfers die Federfenster auf. Bevorzugt sind sowohl in der Nabenscheibe als auch in der Mitnehmerscheibe und dem Deckblech des Torsionsschwingungsdämpfers jeweils sich in einer Umfangsrichtung erstreckende Federfenster vorgesehen, wobei in den Federfenstern eine Feder angeordnet ist.Components of the torsional vibration damper preferably have the spring windows. Preference is given both in the hub disc and in the drive plate and the cover plate of the torsional vibration damper each extending in a circumferential direction provided spring window, wherein a spring is arranged in the spring windows.
Durch das Vorsehen der Entspannungsbohrungen ist eine Spannungsoptimierung des Federfensters erzielbar.By providing the expansion holes a voltage optimization of the spring window can be achieved.
In einer erfindungsgemäßen Ausführungsform weisen die Federfenster innere Eckbereiche und äußere Eckbereiche auf, wobei die Entspannungsbohrungen an wenigstens zwei der Eckbereiche vorgesehen sind.In an embodiment according to the invention, the spring windows have inner corner regions and outer corner regions, wherein the expansion bores are provided on at least two of the corner regions.
Damit ist eine Spannungsoptimierung an unterschiedlichen Eckbereichen möglich. Bevorzugt sind die Eckbereiche Fensterecken des Federfensters.This allows voltage optimization at different corner areas. Preferably, the corner areas are window corners of the spring window.
In einer erfindungsgemäßen Ausführungsform sind die Entspannungsbohrungen unterschiedlich in den Eckbereichen ausgebildet.In an embodiment according to the invention, the expansion bores are formed differently in the corner regions.
Damit sind je nach Anwendungsfall verschiedene Ausgestaltungsformen für die Eckbereiche ausbildbar.Thus, depending on the application, different embodiments for the corner areas can be formed.
In einer erfindungsgemäßen Ausführungsform weisen die Entspannungsbohrungen Formen auf, die
- – wenigsten teilweise rund oder oval sind,
- – einer mathematischen Funktion f(x) = y folgen,
- – sich aus wenigstens zwei Radien zusammensetzen,
- – tropfenförmig ausgebildet sind und/oder
- – als auskragende Bereiche ausgebildet sind.
- Are at least partially round or oval,
- - follow a mathematical function f (x) = y,
- - be composed of at least two radii,
- - Are formed drop-shaped and / or
- - Are designed as cantilevered areas.
Damit ist eine Vielzahl an Ausgestaltungsvarianten möglich.For a variety of design variants is possible.
Die Erfindung wird nun beispielhaft durch Figuren veranschaulicht. Es zeigen:The invention will now be exemplified by figures. Show it:
