Description

Reibungsfeder in Dosenform Gegenstand der Erfindung ist eine Reibungsfeder in Dosenform mit hoher Elastizität, die dazu bestimmt ist, starke Stoß- und Zugkräfte, wie sie z. B. bei Eisenbahnfahrzeugen vorkommen, aufzunehmen und durch Reibungsarbeit fast restlos zu vernichten.Can Friction Spring The invention relates to a friction spring in the form of a can with high elasticity, which is intended to withstand strong impact and tensile forces, how they z. B. occur in railroad vehicles to record and through friction work almost completely destroyed.

Erfindungsgemäß wird dies dadurch ierreicht, daß bei auftretendem Druck oder Zug Reibungsarbeit zwischen dein Dosenrändern, die kegelig ineinandergreifeai, verrichtet wird, bei abnehmender Belastung jedoch nur die lebendige Federkraft zurückwirkt.According to the invention, this is achieved in that when Pressure or tension Frictional work between the edges of the can, which interlock conically is performed, but with decreasing load only the living spring force reacts.

In Abb. i und z der Zeichnung ist die neue Dosenreibungsfeder in verschiedenen Ausführungsarten in der Seitenansicht und im Axialschnitt sowie im Grundriß dargestellt.In Fig. I and z of the drawing the new can friction spring is different Types of execution shown in the side view and in the axial section as well as in the plan.

Die Dosenreibungsfeder,. die außer der runden, auch jede andere `Form aufweisen kann, besteht aus einer ,äußeren schwächeren. und einer inneren stärkeren Schale, die mit ihren kegeligen Rändern derart ineinandergreifen, daß bei Bewegung der Schalen gegeneinander zwischen ihren Rändern eine starke Reibung entsteht.The can friction spring. which apart from the round, also every other `shape may have, consists of an outer weaker. and an inner stronger one Shell, which interlock with their conical edges in such a way that when moving the shells against each other between their edges creates a strong friction.

Bei auftretendem Druck wird also zwischen den Berührungsflächen Reibungsarheit verrichtet, wobei der innere Ring zusammengepreßt und der äußere Ring aufgeweitet wird. Beendet wird die Reibungsarbeit, wenn der Ring der inneren Schale den Boden der äußeren Schale erreicht hat.When pressure occurs, there is no friction between the contact surfaces performed, the inner ring compressed and the outer ring expanded will. The friction work ends when the ring of the inner shell hits the ground the outer shell has reached.

Bei anhaltendem Druck werden die Dosenböden, die flach, konvex oder konkav ausgeführt sind, gestreckt, wodurch die Dosenränder gelüftet werden und dadurch :ein sicheres Zurückgehen der Feder in ihre Anfangsstelle nach Aufhören des Druckes gewährleistet wird. Dadurch, daß die ,äußere Schale in ihrem Querschnitt schwächer gehalten ist, wird dieser Vorgang biegünstigt. Um diesen Rückgang weiter zu beschleunigen, können in die Dosen noch Schraubenfedern eingebaut werden (Abt. i). Zum Durchführen von Stangen können die Dosenreibungsfedern durch= bohrt, die Dosienränder zum Regeln der Federkraft dem Verwendungszweckentsprechend in beliebig viele Segmente unterteilt werden.With sustained pressure, the can bottoms, which are flat, convex or are concave, stretched, whereby the can edges are ventilated and thereby : a sure return of the spring to its starting point after the pressure has stopped is guaranteed. Because the outer shell is weaker in its cross-section is held, this process is flexible. To further accelerate this decline, coil springs can also be built into the boxes (Section i). To carry out The can friction springs can be drilled through rods, the dosing edges for regulating The spring force is divided into any number of segments according to the intended use will.

Abb. i zeigt bei deine Dosenringreibungsfeder mit doppelten Reibflächen, die dazu bestimmt ist, besonders hohen Ansprüchen zu genügen.Fig. I shows your can ring friction spring with double friction surfaces, which is intended to meet particularly high demands.

Die Wirkung .der Dosenreibungsfederkann dadurch erhöht werden, daß mehrere Federn ineinandergebaut werden.The effect of the can friction spring can be increased by several springs can be built into each other.
