Description

Gewickelte Aufweitungs-Schraubenfeder. Gegenstand der Erfindung ist eine gewikkelte Aufweitungs-Schraubenfeder, insbesondere für Hülsenpuffer, und zwar mit zwei oder mehr aus Reibungssegmenten zusammengesetzten Reibungskörpern. Das Neue besteht darin, daß die Reibungssegmente durch schraubengangförmig ohne Zwischenraum gewickeltes Stahlband zusammengehalten werden.Coiled expansion coil spring. The subject of the invention is a coiled expansion coil spring, especially for sleeve buffers, namely with two or more friction bodies composed of friction segments. That What is new is that the friction segments go through helically without a gap wound steel band are held together.

Die Erfindung ist in zwei Ausführungsformen auf der Zeichnung dargestellt. Abb. I zeigt einen Puffer mit drei Reibungskörpern. Die um den vorderen Reibungskörper gelegte Schraubenfeder f" welche nur wenige Windungen besitzt, dient dazu, die leichteren Stöße abzufangen. Beim zweiten und dritten Reibungskörper sind die Windungen der Schraubenfedern f2, ß je nach den Anforderungen, die an den Puffer gestellt werden, vermehrt, um auch die größten Stöße aufzunehmen. Die Führungskegel e1, e2, e3 sind achsial verschiebbar und dienen als Gleitflächen für die Reibungssegmente il, i2,13.The invention is shown in two embodiments in the drawing. Fig. I shows a buffer with three friction bodies. The one around the front friction body laid helical spring f "which has only a few turns, serves the lighter To absorb shocks. In the second and third friction bodies, the windings are the Helical springs f2, ß depending on the requirements placed on the buffer, increased to absorb even the greatest impacts. The guide cones are e1, e2, e3 axially displaceable and serve as sliding surfaces for the friction segments il, i2,13.

In Abb. 2 ist eine Anordnung mit zwei Reibungskörpern dargestellt. Aus Abb.3 ersieht man die letztere Anordnung in gespanntem Zustande. Gehäuse a, Stö.Gel b, Teller c, Tellerboden d, Anschlagbügel g und Grundplatte h sind in ähnlicher Ausführung bereits bekannt.In Fig. 2 an arrangement with two friction bodies is shown. The latter arrangement in the tensioned state can be seen in Fig. 3. Housing a, Stö.Gel b, plate c, plate base d, stop bracket g and base plate h are similar Execution already known.

Beim Stoß schieben sich die einzelnen Führungskegel e1, e2, e3 zusammen und drücken die Reibungssegmente il, 12, 1.3 nach außen, wodurch die gewickelten Schraubenfedern f i, f 2, ß, welche um die Reibungssegmente iL, i2, i3 gelegt sind, aufgeweitet werden. Durch die auf zwei Reibungsflächen erzeugte Reibung wird der größte Teil der Stoßkraft vernichtet, und daher ist der Rückstoß ein weicher.During the impact, the individual guide cones e1, e2, e3 push together and press the friction segments il, 12, 1.3 outwards, whereby the wound coil springs f i, f 2, ß, which are placed around the friction segments iL, i2, i3, expand will. Due to the friction created on two friction surfaces, most of the impact force is dissipated, and therefore the recoil is a softer one.
