Description

Gewickelte Aufweitungs-Schraubenfeder In der Patentschrift 426 370 ist ene gewickelte Aufw eitunigs-Schraubenfeder beschrieben, welche sich besonders zur Verwendung in Hülsenpuffern eignet und durch die Benutzung eines schraubengangförmig ohne Zwischenraum gewicl#:elten Stahlbandes, das zum Zusammenhalten von Reibungssegmenten dient, b kennmichnet ist.Coiled widening coil spring Patent 426 370 describes a coiled widening coil spring which is particularly suitable for use in sleeve buffers and is characterized by the use of a helical without a gap, which is used to hold friction segments together .

Die vorliegende Zusatzerfindung besteht darin, daß zur Herstellung des schraubelgangförmig ohne Zwischenraum gewickelten Sta:hlhandes nicht Stahl von. quadratüschem oder rechteckigem oder ähali:chean Querschnitt, sondern Stahl von profilförmigem Querschnitt, d. h. sogenanntem Profilband, verwendet wird. In dieser Weise hergestellte Federn besitzen durch das erhöhte Widerstandsmüment des Federquerschnittes eine höhere Tragkraft beim Aufwehen; gleichzeitig wird durch Verwendung von Profilband eine Gewichtsersparnis ;erziel.The present additional invention is that for production of the helical steel handle, which is wound without a gap, is not made of steel. square or rectangular or ähali: chean cross-section, but steel from profile-shaped cross-section, d. H. so-called profile tape is used. In this Well-made springs have due to the increased resistance of the spring cross-section a higher load capacity when blowing up; at the same time by using profile tape a weight saving; achieve.

Einige der hauptsächlich in Betracht kommenden Querschnittsformen des Profilbandes sind als Beispiele in der Zeichnung dargestellt.Some of the main cross-sectional shapes to consider of the profile band are shown as examples in the drawing.
