Description

Aus voneinan@dpr nabhängigen, sich mit Keilflächen berührenden Teilen bestehende Feder. Die Erfindung bezieht sich auf Federn nach Patent 44174I und besteht darin, daß die aus im Querschnitt gewölbten, ineinander= geschraubten Streifen bestehende Feder in der Weise zusammengesetzt ist, daß die Federstreifen in unbelastetem Zustande in achsialer Richtung Spiel gegeneinander besitzen.From mutually independent parts that come into contact with wedge surfaces existing spring. The invention relates to and consists of springs according to patent 44174I in that the strips consisting of curved cross-section and screwed into one another = The spring is assembled in such a way that the spring strips are in the unloaded state have play against each other in the axial direction.

Auf der Zeichnung ist eine Ausführungsform des Gegenstandes der Erfindung in achsiaiem Schnitt dargestellt.In the drawing is an embodiment of the subject matter of the invention shown in axial section.

Die Feder besteht aus zwei im Querschnitt gewölbten, ineinandergeschraubten Streifen A und B, die ihre konvexe Seite einander zu= kehren. Die beiden Streifen sind an ihren Enden, z. B. einerseits an einer Pufferhülse und anderseits an dem Pufferstößel, festgelegt und von solchen gegenseitigen Abmessungen, daß sie in unbelastetem Zustande mit Spiel ineinandergreifen. Beim Zusammendrücken der Feder wirken die beiden Streifen A und B, solange sie gegeneinander Spiel haben, wie gewöhnliche, auf Verdrehung beanspruchte Schraubenfedern; die Federkraft der Feder ist hierbei verhältnismäßig gering. Wird die Feder jedoch so weit belastet, daß die Streifen aufeinandergleiten, so tritt in bekannter Weise eine Keilwirkung zwischen der. äußeren und der inneren Windung ein. Der äußere Streifen B ist daher bestrebt, seinen Durchmesser zu vergrößern, während der innere Streifen A seinen Durchmesser zu verringern sucht. Die Streifen A und B werden daher nunmehr im wesentlichen nur auf Zug oder Druck beansprucht und sind daher in der Lage, eine verhältnismäßig große Kraft aufzunehmen.The spring consists of two strips A and B, curved in cross-section, screwed into one another, with their convex sides facing each other. The two strips are at their ends, e.g. B. on the one hand on a buffer sleeve and on the other hand on the buffer plunger, set and of such mutual dimensions that they interlock in the unloaded state with play. When the spring is compressed, the two strips A and B act, as long as they have play against one another, like normal helical springs subject to torsion; the spring force of the spring is relatively low here. However, if the spring is loaded so much that the strips slide on each other, a wedge effect occurs in a known manner between the. outer and inner turn. The outer strip B therefore tries to increase its diameter, while the inner strip A tries to reduce its diameter. The strips A and B are therefore now essentially only subjected to tension or compression and are therefore able to absorb a relatively large force.

Die beschriebene Einrichtung ermöglicht, in einfacher Weise Federn nach dem Hauptpatent herzustellen, die bei Beginn der Belastung eine geringe, dann aber rasch wachsende Federkraft besitzen.The device described enables springs in a simple manner to manufacture according to the main patent, which at the beginning of the load a low, then but have a rapidly growing spring force.

PATENTANSPRUCH: Aus voneinander unabhängigen, sich mit Keilflächen berührenden Teilen bestehende Feder nach Patent 441741 dadurch gekennzeichnet, daß die die Feder bildenden, im Querschnitt gewölbten und ineinandergeschraubten Streifen (A, B) in der Weise zueinander angeordnet sind, daß die Streifen (A, B) in unbelastetem Zustande der Feder in ächsialer Richtung Spiel gegeneinander besitzen. CLAIM: A spring according to Patent 441741, consisting of independent parts that touch wedge surfaces, characterized in that the strips (A, B) forming the spring, arched in cross-section and screwed into each other, are arranged in such a way that the strips (A, B ) have play against each other in the axial direction in the unloaded state of the spring.
