Abstract
Description
Die Erfindung betrifft eine Schraubenfeder gemäß Oberbegriff des Anspruchs 1.The The invention relates to a coil spring according to the preamble of the claim 1.
Schraubenfedern werden als Druck- oder Zugfedern für die unterschiedlichsten Anwendungsbereiche benötigt, wobei auch die Dimensionierung der Schraubenfedern von der jeweiligen Anwendung abhängt. Großdimensionierte Schraubenfedern werden beispielsweise im Fahrwerksbereich von Kraftfahrzeugen verwendet.coil springs be used as compression or tension springs for a wide variety of applications needed wherein also the sizing of the coil springs of the respective Application depends. large-sized Coil springs, for example, in the chassis of motor vehicles used.
Bei bekannten Druck- und Zugfedern, die als Schraubenfedern ausgebildet sind, entsteht beispielsweise beim Zusammendrücken ein Drehmoment, welches dazu führt, dass sich die Schraubenfeder aufwickeln will. Das dabei auf die Enden oder Ösen der Schraubenfeder wirkende Drehmoment kann insbesondere bei großen Hüben sehr stören. Es können störende Geräusche entstehen und die auftretende Torsionsspannung kann zu einem vorzeitigen Federbruch führen. Diese Problematik tritt insbesondere dann auf, wenn Schraubenfedern mit einer Nennlast belastet werden, die gleich oder höher ist als das Dreifache der Vorlast. Als Vorlast ist dabei die Kraft zu verstehen, mit der die Feder in Einbaulage vorgespannt ist.at known compression and extension springs, which are designed as coil springs are, for example, arises when squeezed a torque, which causes that the coil spring wants to wind up. This on the Ends or eyelets the torque acting on the coil spring can be very high, especially in the case of large strokes to disturb. It can disturbing Sounds arise and the occurring torsional stress can lead to premature Lead spring break. This problem occurs in particular when coil springs be loaded with a nominal load equal to or higher than three times the preload. The preload here is the power to understand with which the spring is biased in the installed position.
Der Erfindung liegt die Aufgabe zugrunde, eine Schraubenfeder, die als Druck- oder Zugfeder ausgebildet sein kann, zu schaffen, bei der an den Federenden bei Belastung möglichst keine oder nur geringe Torsionsspannungen auftreten.Of the Invention is based on the object, a coil spring, as Compression or tension spring can be designed to provide, in the At the spring ends under load as little or no possible Torsional stresses occur.
Die Lösung dieser Aufgabe erhält man durch die im Anspruch 1 angegebenen Merkmale. Die erfindungsgemäße Schraubenfeder besteht aus wenigstens zwei gegenläufigen Windungsabschnitten, die vorzugsweise quasi spiegelsymmetrisch ausgebildet sind. Die gegenläufigen Windungsabschnitte sind so bemessen, dass bei einer Belastung der Schraubenfeder sich die in beiden gegenläufigen Windungsabschnitten aufbauenden Torsionsmomente gegenseitig aufheben, wobei der Mittelteil bei Belastung eine freie Drehbewegung ausführt.The solution receives this task one by the features specified in claim 1. The coil spring according to the invention consists of at least two opposite winding sections, which are preferably formed quasi mirror-symmetrical. The opposing Winding sections are dimensioned so that under a load of Coil spring in both opposite turns sections abolish constructive torsional moments, the middle part performs a free rotation when loaded.
Der Übergang zwischen den beiden gegenläufigen Windungsabschnitten wird vorzugsweise von einem Umkehrbogen gebildet, so dass auch in diesem Bereich keine erhöhte Bruchgefahr besteht.The transition between the two opposing ones Windungsabschnitten is preferably formed by a reverse arc, so that there is no increased risk of breakage even in this area.
Die erfindungsgemäße Schraubenfeder kann als einstückiges Teil oder aber auch aus zwei separaten Windungsabschnitten bestehen, von denen der eine Windungsabschnitt linksgewickelt und der andere Windungsabschnitt rechtsgewickelt ist. Beide Windungsabschnitte können fest miteinander verbunden sein, beispielsweise mittels einer Klebeverbindung oder durch eine Verschweißung.The inventive coil spring can as one piece Part or even consist of two separate Windungsabschnitten, of which one winding section wound on the left and the other Winding section is wound right-hand. Both winding sections can be firmly connected to each other, for example by means of an adhesive bond or by welding.
Die Erfindung wird nachfolgend anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert.The Invention will now be described with reference to the drawing embodiments explained in more detail.
