Abstract
Dämpfungskörper für Schraubenfedern (5), welche Kupplungsservofedern sind, wobei der Dämpfungskörper (6) bei entspannter Schraubenfeder, also in unbetätigtem Zustand der Kupplungsservofeder, an der Schraubenfeder (5) mit leichter Vorspannung anliegt und in betätigtem zustand hingegen nicht mehr anliegt, und wobei der Dämpfungskörper mit einem Schmiermittel versehen ist und aus einem formstabilen Gewebe besteht.Damping body for coil springs (5), which are clutch servo springs, where the damping body (6) rests against the coil spring (5) with a slight pretension when the coil spring is relaxed, i.e. when the clutch servo spring is not actuated, and no longer rests in the actuated state, and the The damping body is provided with a lubricant and consists of a dimensionally stable fabric.
Description
Die Erfindung betrifft einen Dämpfungskörper für Schraubenfedern nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a damping body for coil springs according to the preamble of
Schraubenfedern, die plötzlich entlastet werden, neigen zu Schwingungen, die sich dann als störende (Schwirr-) Geräusche bemerkbar machen.Coil springs, which are suddenly relieved, tend to vibrate, which then manifests itself as annoying (buzzing) noises.

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.Based on this prior art, it is an object of the invention to provide a damping body for coil springs, which is inexpensive to manufacture and assembly and has a long service 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.This object is achieved with the features of
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.Thus, it is proposed to use an aramid fiber as the fabric. Aramid fibers are characterized by high strength. A fabric made from this is at the same time dimensionally stable and wear-resistant, so that good damping properties and a long service life are ensured. It is also possible to carry out the fabric as a non-woven whose structure leads to a further increased life.
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.As a lubricant, Teflon is preferably used. Teflon does not attack the fabric or the surrounding components and is durable for a long time. 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 is done by rolling and gluing. The tools used for this purpose are simple and since only a few tools are needed, the production is also very cost-effective. For gluing an overlap area is 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.In principle, it is also possible to produce the damping body as a woven tube or to sewn a tissue section so that a tubular body is formed.
Die geometrischen Abmessungen des Dämpfungskörpers sind so zu wahlen, 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 to be chosen so that it rests with relaxed spring on the spring with slight bias. In a compression spring of the damping body is located inside the spring, at a tension spring outside of the spring.
Ein Ausführungsbeispiel der Erfindung ist nachstehend anhand des in den Figuren dargestellten Ausführungsbeispieles näher erlautert.An embodiment of the invention is explained in more detail below with reference to the embodiment shown in the figures.
