Description
Hülsenfeder Gegenstand der Erfindung ist eine aus konzentrisch ineinandergesteckten zylindrischen, längs geschlitzten Federhälsen bestehende Hülsenfeder mit übereinanderliegenden Schlitzen für die gesamte Feder und einem im Federinnern liegenden Federbegrenzungskern. Die Erfindung besteht darin, daß der Durchmesser des Federbegrenzungskernes kleiner als der Innendurchmesser der Feder ist, so daß sich diese letztere bei wechselnder Federbelastung auf dem Kern abwälzen kann. Dadurch wird erreicht, daß die Federcharakteristik sich asymptotisch der Federbegrenzungslinie nähert, die Feder also selbst bei hohen Beanspruchungen noch elastisch bleibt. Das Abwälzverfahren ist an sich bei Federungen bekannt. Neu ist indessen seine Anwendung bei Hülsenfedern der gekennzeichneten Art, deren Anwendungsbereich dadurch wesentlich erweitert und insbesondere auf das Gebiet der elastischen Kupplungen ausgedehnt werden kann.Sleeve spring The subject of the invention is one of concentrically nested cylindrical, longitudinally slotted spring necks existing sleeve springs with one above the other Slots for the entire spring and a spring limiting core located inside the spring. The invention consists in that the diameter of the spring limiting core is smaller than the inner diameter of the spring, so that the latter changes with changing Can roll spring load on the core. This ensures that the spring characteristic approaches the spring delimitation line asymptotically, i.e. the spring even at high Stresses still remains elastic. The rolling process is per se with suspensions known. What is new, however, is its use in the case of sleeve springs Art, the scope of which is thereby significantly expanded and in particular to the The area of elastic couplings can be expanded.
Zur Verhinderung einer unzulässigen Verschiebung der einzelnen Federhülsen gegeneinander trägt der Federbegrenzungskern eine Rippe, die in den Längsschlitz der Feder eingreift und sich über die ganze Federlänge erstreckt. Gegenüber den bisher hierfür verwendeten Keilen oder Wulsten, die die Federhülsen nur einseitig halten, oder gegenüber den an den Federhülsen angebrachten Sicherungswarzen bietet diese Anordnung den Vorteil, daß eine ungleichmäßige Beanspruchung der Feder vermieden wird und das freie Federspiel erhalten bleibt.To prevent inadmissible displacement of the individual spring sleeves against each other, the spring limiting core bears a rib that is inserted into the longitudinal slot the spring engages and extends over the entire length of the spring. Compared to the wedges or beads previously used for this purpose, which only have the spring sleeves on one side hold, or offers opposite the locking lugs attached to the spring sleeves this arrangement has the advantage that uneven loading of the spring is avoided and the free spring play is maintained.
In der Zeichnung ist ein Ausführungsbeispiel der neuen Feder dargestellt, und zwar zeigt Abb. i eine Seitenansicht und Abb. a einen Querschnitt.In the drawing, an embodiment of the new spring is shown, namely Fig. i shows a side view and Fig. a shows a cross section.
Die Feder besteht aus einzelnen ineinandergesteckten Hülsen a, b, c und d aus rund gebogenen und gehärteten Blechen, die genau passend ineinandergesteckt sind. Je nach der Zahl der verwendeten Hülsen und ihrer Wandstärke kann die Elastizität der Feder in weitesten Kreisen geändert werden. Im Innern der Feder ist ein starrer Federbegrenzungskerne vorgesehen, dessen Außendurchmesser kleiner ist als der Innendurchmesser der innersten Hülsea, so daß sich die Feder bei wechselnder Federbelastung auf ihm abwälzen kann. Dadurch wird eine Begrenzung des Federweges herbeigeführt und erreicht, daß die Federcharakteristik sich asymptotisch der Federbegrenzungslinie nähert, so daß also selbst bei sehr hoben Belastungen die Feder noch elastisch bleibt.The spring consists of single nested sleeves a, b, c and d made of curved and hardened metal sheets, which are nested to fit exactly. Depending on the number of sleeves used and their wall thickness, the elasticity of the spring can be changed to a large extent. Inside the spring a rigid spring delimitation core is provided, the outside diameter of which is smaller than the inside diameter of the innermost sleeveea, so that the spring can roll over it when the spring load changes. This brings about a limitation of the spring travel and achieves that the spring characteristic asymptotically approaches the spring delimitation line, so that the spring remains elastic even with very high loads.
Zur Verhinderung einer unzulässigen Verschiebung der einzelnen Federhülsen gegeneinander ist an dem Kern e eine Rippe f angebracht, die in den gemeinsamen Schlitz der Federhülsen eingreift und sich über dessen ganze Länge erstreckt. Diese Anordnung 'bietet Vorteil, daß ein einseitiges Festhalten der Federhülsen, das leicht zum Bruch der Feder führen kann, vermieden wird.To prevent impermissible displacement of the individual spring sleeves relative to one another, a rib f is attached to the core e which engages in the common slot of the spring sleeves and extends over its entire length. This arrangement offers the advantage that one-sided holding of the spring sleeves, which can easily lead to breakage of the spring, is avoided.
Die Hülsenfeder kann überall dort zur Anwendung gelangen, wo bisher Schrauben-, Spiral- oder Blattfedern verwendet wurden. Insbesondere eignet sie sich für die Verwendung von elastischen Kupplungen, Schwingungsdämpfern u. dgl.The sleeve spring can be used anywhere where previously Helical, spiral or leaf springs were used. It is particularly suitable for the use of elastic couplings, vibration dampers, etc.
