Description
Federkörper Die Erfindung geht aus von einem Federkörper mit einer beliebig gestalteten Bohrung in der Hauptkraftrichtung, der sowohl als Druck- als auch als Zugfederkörper Verwendung finden kann.Spring body The invention is based on a spring body with a arbitrarily designed bore in the main direction of force, both as pressure and can also be used as a tension spring body.
Der Erfinder hat sich zur Aufgabe gestellt, einen solchen Federkörper bei Erzielung einer zumindest zu einem Teil steilen Federkennlinie möglichst leicht zu gestalten.The inventor has set himself the task of creating such a spring body as easily as possible when achieving a spring characteristic that is at least partly steep to design.
Erfindungsgemäß wird dies dadurch erreicht, daß der Federkörper aus wabenförinig angeordneten, an ihren Stirnseiten offenen Kammern besteht, deren Längsachsen die Bohrung durchsetzen.According to the invention this is achieved in that the spring body from honeycomb arranged, open at their front sides chambers, whose longitudinal axes enforce the hole.
Die Bildung der einzelnen Kammern kann hierbei in verschiedenster Weise vorgenommen werden. So ist es z. B. möglich, die Kammern durch Ausbohren aus massiven Körpern oder den Federkörper als Ganzes durch Gießen, Pressen oder ähnliche Verfahren herzustellen. Eine andere Art der Herstellung 1-iesteht darin, daß die einzelnen Kammerwände aus dünnt, andigeni Werkstoff hergestellt t%-erden und der Federkörper aus diesen Einzelelementen zusammengesetzt wird. Das Zusammenfügen des Körpers kann hierbei durch geeignete Fertigungsverfahren erfolgen, z. B. durch Sintern, Schweißen. Löten. Nieten od. dgl. oder auch durch Leimen u. dgl. Für besondere Anwendungszwecke ist es auch mö-lich. mehrere derartige Federkörper als Einzelelemente lose, d. h. ohne eine feste Verbindung miteinander. übereinander anzuordnen.The formation of the individual chambers can be varied here Way to be made. So it is z. B. possible to drill out the chambers massive bodies or the spring body as a whole by casting, pressing or the like Process to manufacture. Another way of manufacturing 1-i is that the individual Chamber walls made of thin, andigeni material t% -erden and the spring body is composed of these individual elements. That The body can be joined together using suitable manufacturing processes, z. B. by sintering, welding. Soldering. Rivets or the like or by gluing and the like. Like. For special purposes it is also possible. several such spring bodies loose as individual elements, d. H. without a solid connection with each other. on top of each other to arrange.
Die Wirkungsweise eines solchen Federkörpers beruht darauf, daß sich die einzelnen t: abeiiförmig zueinander angeordneten Kamtnern bei Belastung gewölbeartig gegeneinander abstützen, so daß die einzelnen Kammerwände in erheblichem 1lal@ Ztig- oder Druckspannungen unterworfen sind. Hieraus ergibt sich gegenliiber bekannten Federkörpern eine läesonders gute Ausnutzung des Federwerkstoffes und somit ein geringer Aufwand an Werkstoff.The operation of such a spring body is based on the fact that the individual chambers, arranged in the shape of a egg, become vault-like when loaded support each other, so that the individual chamber walls in considerable 1lal @ Ztig- or are subject to compressive stresses. This results in comparison to known Spring bodies allow a particularly good utilization of the spring material and thus a low material expenditure.
In weiterer Ausgestaltung der Erfindung können für solche Fälle. in denen im Anfangsbereich der Belastung ein flacherer Anstieg der Federketinlinie erwünscht ist, an den sich dann der steilere Anstieg anschließt, zwischen den einzelnen Kammern Zwischenräume vorgesehen sein, so daß das Abstützen der einzelnen nebeneinanderliegenden Kammergewölbe gegeneinander erst nach einem gewissen Federungsweg erfolgt.In a further embodiment of the invention, for such cases. in those in the initial area of the load have a flatter rise in the spring ketin line is desirable, which is then followed by the steeper ascent, between the individual Chambers gaps can be provided so that the support of the individual juxtaposed Chamber vault against each other takes place only after a certain suspension travel.
In der Zeichnung sind zwei beispielsweise Ausführungsmöglichkeiten der Erhndung dargestellt.In the drawing, there are two possible design options, for example of the erhndung shown.
Abb. i stellt eine beispielsweise Ausführungsforin nach der Erfindung dar, bei welcher der Grundkörper i aus dem Vollen hergestellt ist und die Kammern 2 eingearbeitet sind. Die einzelnen Reihen der Kammern 2 sind wahenförmig zueinander angeordnet.Fig. I shows an exemplary embodiment according to the invention represents, in which the base body i is made from the solid and the chambers 2 are incorporated. The individual rows of the chambers 2 are wave-shaped to one another arranged.
Abb. 2 zeigt in Abwicklung einen aus Band= material hergestellten Federkörper. bei dein die Kammern 2 der einzelnen Reihen dureli halten von Bändern 3 gebildet werden. Beiderseitig ist der Federkörper durch Abdeckplatten 4 abgeschlossen. Bei dieser Ausführungsform ist die ilüglichkeit einer geknickten Federkennlinie verwirklicht. da sich die nebeneinanderliegendenKammerwände im unbelasteten Zustand nicht gegenseitig berühren. sondern durch Hohlräume ; getrennt sind. Bei Belastung werden zunächst die Kammerwände vorwiegend auf Biegung beansprucht, his sieh die Gewölbewirkung nach L?berbrückung der Hohlräume 5 einstellt.Fig. 2 shows a development made of tape = material Spring body. in the case of your the chambers 2 of the individual rows dureli hold by ribbons 3 are formed. The spring body is closed on both sides by cover plates 4. In this embodiment there is the possibility of a kinked spring characteristic realized. since the adjacent chamber walls are in the unloaded state don't touch each other. but through cavities; are separated. Under pressure the chamber walls are initially subjected to bending stresses, up to and including the Arching effect after bridging the cavities 5 sets.
