Description

Geschlagene oder gewalzte Kegeltopfreibungsfeder. Gegenstand der vorliegenden Erfindung ist eine Verbesserung der durch das Patent 446 093 geschützten geschlagenen oder gewalzten Kegeltopfreibungsfeder. Die Erfindung bezweckt die Beseitigung der bei geschlitzten geradlinig-kegeligen Reibungsfedern auftretenden Fehler, die darin bestehen, daß infolge der, verschieden großen Segmentradien der Abwicklung zwischen der belasteten und unbelasteten Feder außer der normalen Flachkantbeanspruchung auch eine Hochkantbeanspruchung der Federquerschnitte auftritt, was sowohl eine außergewöhnlich hohe Materialbeanspruchung als auch ein Fressen der zwischen dein Federrand und dem Auflagering befindlichen Gleitfläche wegen des ungleichmäßig verteilten Flächendruckes zur Folge hat.Beaten or rolled conical cup friction spring. The subject of the present invention is an improvement of the hammered or rolled conical cup friction spring protected by the patent 446 093. The invention aims to eliminate the errors occurring in slotted straight-conical friction springs, which consist in the fact that, due to the differently large segment radii of the development between the loaded and unloaded spring, in addition to the normal flat edge stress, there is also an upright stress on the spring cross-sections, which is both extraordinarily high Material stress as well as seizure of the sliding surface located between the spring edge and the support ring due to the unevenly distributed surface pressure result.

Das Neue der Erfindung besteht in der Anordnung gewölbtkegeliger Reibungsflächen zwischen den Federn und den Zwischenringen, wodurch in jeder Lage des Federtopfes sowohl im unbelasteten als auch im höchstbelasteten Zustande eine genaue Anlage ohne Zwischenraum und damit auch ein gleichmäßig verteilter Flächendruck auf der ganzen Reibungsfläche erzielt wird.The novelty of the invention consists in the arrangement of convex-conical friction surfaces between the springs and the intermediate rings, whereby in every position of the spring pot an exact system both in the unloaded and in the highly loaded condition without a gap and thus an evenly distributed surface pressure on the entire friction surface is achieved.

Abb. i der Zeichnung zeigt die in einem Hülsenpuffer mit Vorspannung eingebaute neue Feder als Körper von gleicher Festigkeit infolge trapezförmigen Querschnittes. In Abb. z ist dieselbe in zusammengedrücktem Zustande dargestellt. Eine Drehbewegung fällt fort, da sämtliche Federn f der Federsäule jeden beliebigen Verdrehungswinkel gegeneinander haben dürfen, wodurch deren Herstellung als Massenartikel durch Spezialwalzwerke, ähnlich der Ringfederfabrikation, ausgeführt werden kann.Fig. I of the drawing shows the in a sleeve buffer with pretension built-in new spring as a body of equal strength due to trapezoidal shape Cross-section. In Fig. Z the same is shown in a compressed state. There is no rotational movement, since all springs f of the spring column are any Rotation angles against each other are allowed to have, whereby their manufacture as mass-produced articles can be carried out by special rolling mills, similar to the manufacture of ring springs.

Zur Entlastung der Zwischenringe e ist zwischen den Ringen f der Federsäule im zusammengedrückten Zustande noch etwas Spiels vorgesehen, weshalb die Hubbegrenzung durch Aufsitzen des Stößels c erreicht werden muß. Abb. 3 zeigt einen einzelnen Federtopf f der Erfindung im Gegensatz zu einer fehlerhaften Feder f" alter Bauart in Abb. q. mit den dazugehörigen Abwicklungen. In Abb. 3 sind die Segmentradien y1 und y2 gleich, während sie gemäß Abb. q. verschieden sind, wie die strichpunktierte Eintragung zeigt. Um diese fehlerhafte Radierdifferenz müssen sich die Federn alter Bauart außer der normalen Beanspruchung auch auf Hochkant durchbiegen, was, zur Folge hat, daß* sie eine nur verhältnismäßig kurze Lebensdauer haben.To relieve the intermediate rings e is between the rings f of the spring column In the compressed state there is still some play provided, which is why the stroke limitation must be achieved by seating the plunger c. Fig. 3 shows a single one Spring cup f of the invention in contrast to a faulty spring f "old design in fig.q. with the associated transactions. In Fig. 3 are the segment radii y1 and y2 are the same, while according to Fig. q. are different, like the dash-dotted line Entry shows. The feathers have to age to accommodate this incorrect erasing difference In addition to normal stress, the design also bends upright, what, for The consequence is that * they only have a relatively short lifespan.
