Abstract
Description
Die Erfindung betrifft einen Dämpfungskörper für Schraubenfedern nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a damping body for coil springs according to the preamble of claim 1.
Schraubenfedern, die plötzlich entlastet werden, neigen zu Schwingungen, die sich dann als störende (Schwirr-) Geräusche bemerkbar machen.Coil springs, the sudden be relieved, tend to oscillate, which then becomes disturbing (buzzing) Sounds to make noticable.
Aus dem DE-GbM 1 779 250 U1 ist es bereits bekannt, zur Unterdrückung von störenden Federschwingungen im Inneren einer Druckfeder einen Dämpfungskörper anzuordnen. Der Dämpfungskörper besteht aus einem geschlitzten, federnden Rohr, das auch bei nicht gespannter Feder an den Federwindungen anliegt. Der Dämpfungskörper ist an seiner Oberfläche mit einer Schmiermittelschicht versehen.Out DE-GbM 1 779 250 U1 it is already known for the suppression of disturbing Federschwingungen inside a compression spring to arrange a damping body. The damping body exists from a slotted, springy tube, even when not tensioned Spring rests against the spring coils. The damping body is on its surface with a lubricant layer provided.

der
Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung, einen Dämpfungskörper für Schraubenfedern zu schaffen, der günstig in der Herstellung und Montage ist und eine große Lebensdauer aufweist.outgoing From this prior art, it is an object of the invention to provide a Damping body for coil springs to create, the cheap is in production and assembly and has a long life.
Diese Aufgabe wird mit den Merkmalen des Patentanspruches 1 gelöst. Erfindungsgemäß wird vorgeschlagen, einen gattungsgemäßen Dämpfungskörper aus einem formstabilen Gewebe herzustellen. Gewebe ist günstig in der Herstellung und Verarbeitung, so dass der Dämpfungskörper preiswert herzustellen ist und leicht an die geometrischen Verhältnisse der Feder anpassbar ist. Darüber hinaus weist das Gewebe den besonderen Vorteil auf, dass es das Schmiermittel aufnehmen und so einen Schmiermittelvorrat bilden kann. Die Lebensdauer des Dämpfungskörpers ist dadurch sehr hoch.These The object is achieved by the features of claim 1. According to the invention, it is proposed a generic damping body to produce a dimensionally stable tissue. Tissue is cheap in the production and processing, so that the damping body inexpensive to produce is and easily adaptable to the geometric relationships of the spring is. About that In addition, the fabric has the particular advantage that it is the Take up lubricant and form a lubricant reservoir can. The life of the damping body is very high.
Vorteilhafte Ausbildungen der Erfindung sind in den Unteransprüchen beschrieben.advantageous Embodiments of the invention are described in the subclaims.
So wird vorgeschlagen, als Gewebe eine Aramidfaser zu verwenden. Aramidfasern zeichnen sich durch hohe Festigkeit aus. Ein hieraus hergestelltes Gewebe ist gleichzeitig formstabil und verschleißfest, so dass gute Dämpfungseigenschaften und eine hohe Lebensdauer gewährleistet sind. Es ist darüber hinaus möglich, das Gewebe als Vlies auszuführen, dessen Struktur zu einer nochmals gesteigerten Lebensdauer führt.So It is proposed to use as an aramid fiber fabric. aramid are characterized by high strength. A made from this Fabric is at the same time dimensionally stable and wear-resistant, so that good damping properties and ensures a long service life are. It is about it out possible, to perform the fabric as a fleece, whose structure leads to a further increased lifetime.
Als Schmiermittel wird vorzugsweise Teflon verwendet. Teflon greift weder das Gewebe noch die umgebenden Bauteile an und ist über lange Zeit beständig. Der Auftritt des Schmiermittels erfolgt vorzugsweise durch Tränken des fertigen Dämpfungskörpers.When Lubricant is preferably used Teflon. Teflon attacks neither the fabric nor the surrounding components and is over long Time resistant. The appearance of the lubricant is preferably carried out by soaking the finished damping body.
Die Herstellung des Dämpfungskörpers erfolgt durch Rollen und Kleben. Die hierzu verwendeten Werkzeuge sind einfach und da nur wenige Werkzeuge benötigt werden, ist die Herstellung auch sehr kostengünstig. Zum Verkleben ist ein Überlappungsbereich vorzusehen. Der Schmiermittelauftrag erfolgt erst nach dem Verkleben.The Production of the damping body takes place by rolling and gluing. The tools used for this purpose are simple and because only a few tools are needed are, the production is also very inexpensive. For gluing is an overlap area provided. The lubricant is applied only after bonding.
Grundsätzlich ist es auch möglich, den Dämpfungskörper als Webschlauch herzustellen oder einen Gewebeabschnitt so zu vernähen, dass ein rohrförmiger Körper entsteht.Basically it also possible the damping body as To make a woven tube or to sew a section of tissue so that a tubular body arises.
Die geometrischen Abmessungen des Dämpfungskörpers sind so zu wählen, dass er bei entspannter Feder an der Feder mit leichter Vorspannung anliegt. Bei einer Druckfeder liegt der Dämpfungskörper innen an der Feder, bei einer Zugfeder außen an der Feder an.The geometric dimensions of the damping body are so to choose that he relaxed spring on the spring with slight preload is applied. In a compression spring of the damping body is located inside the spring, at a tension spring outside on the spring.
