Description
Tellerfeder für Kupplungen, insbesondere für Kraftfahrzeugkupplungen, und Verfahren zu ihrer Herstellung Die Erfindung bezsieht sich auf Tellerfedern für Kupplungen, insbesondere für Kraftfahrzeugkupplungen, bei denen radial oder schräg nach innen ragende Zungen vorgesehen sind. Diese Zungen -dienen ,im allgemeinen als Angriffspunkte für die mit dem Ausrücken (Druckstück) verbundene Anlaufscheibe. Diese Anlaufscheibe kann drehbar, .beispielsweise in Kugeln, gelagert sein; sie kann aber auch stillstehen und so einen Gleitkörper, beispielsweise aus Stahl, bilden.Disk springs for clutches, in particular for motor vehicle clutches, and method of making them. The invention relates to disc springs for clutches, especially for motor vehicle clutches, where radial or obliquely inwardly projecting tongues are provided. These tongues serve, in general as points of application for the thrust washer connected to the disengagement (pressure piece). This thrust washer can be rotatably mounted, for example in balls; she but can also stand still and thus form a sliding body, for example made of steel.
Die Zungentellerfeder wurde bisher als Ganzes gleichmäßig gehärtet. Infolge der Anlage der einzelnen Spitzen der Zungen der Tellerfeder am Druckring oder der Anlaufscheibe sind diese Spitzen einem sehr erheblichen Verschleiß ausgesetzt, der bisher in Kauf genommen wurde.The tongue disc spring has been hardened evenly as a whole. As a result of the installation of the individual tips of the tongues of the disc spring on the pressure ring or the thrust washer, these tips are exposed to very considerable wear, which has been accepted so far.
Dieser Nachteil wird bei Tellerfedern für Kupplungen, insbesondere Kraftfahrzeugkupplungen, mit nach,innen zu radial oder schräg verlaufenden Zungen gemäß ;der Erfindung dadurch beseitigt, daß die Tellerfeder an .ihren inneren Zungenspitzen eine größere Härte aufweist als in der äußeren Zone.This disadvantage is particularly evident in the case of disc springs for clutches Motor vehicle clutches with tongues extending radially or obliquely inwards in accordance with the invention eliminated in that the disc spring is attached to its inner tongue tips has a greater hardness than in the outer zone.
Vorteilhaft wird dabei so vorgegangen, daß die Tellerfeder zunächst als Ganzes in bekannter Weise auf Federhärte gebracht wird und dann die Zungenspitzen durch eine zweite, nur sie erfassende Härtung zusätzlich auf eine höhere Härte gebracht werden.It is advantageous to proceed in such a way that the plate spring is initially as a whole is brought to spring hardness in a known manner and then the tongue tips by a second hardening that only affects them, it is additionally brought to a higher hardness will.
Durch die Erfindung wird also die Härtung der Federscheibe derart vorgenommen, daß die inneren Zungenenden der Tellerfederscheibe einen höheren Härtegrad erhalten als der übrige Teil der Zungen und die nicht durchbrochene Ringzone :der Tellerfeder aufweisen. Durch diese Maßnahme können .die bekannten Verschleißerscheinungen an den Spitzen der Tellerfedern für Kupplungen vermieden werden, und es wird somit eine weitaus größere Betriebsdauer der Tellerfeder und er Kupplung erreicht.With the invention so the hardening of the spring washer is so made that the inner tongue ends of the Belleville washer have a higher degree of hardness preserved than the rest of the tongues and the uninterrupted ring zone: the Have disc spring. This measure can prevent the known signs of wear at the tips of the disc springs for clutches can be avoided, and thus it will a much longer service life of the disc spring and he clutch achieved.
Die der Erfindung gemäß vorgesehene größere Härte der Zungenenden der Tellerfedern ist nicht nur bei Kupplungen mit Anlaufscheiben von Vorteil, sondern auch bei Kupplungen, in denen diese Zungen unmittelbar in radiale, wechselweise seitlich ,gegeneinander versetzte Öffnungen des Druckstückes eingreifen und das vorzugsweise aus gezogenem Blech hergestellte Druckstück von den Zungen gehalten wird. Da auch bei dieser Konstruktion die Enden der Zungen besonders beansprucht sind, wird !der Verschleiß der Zungenspitzen infolge der weit größeren Härte an diesen Stellen herabgesetzt.The greater hardness of the tongue ends provided according to the invention the disc springs is not only beneficial for clutches with thrust washers, but even with clutches in which these tongues are directly in radial, alternately laterally, mutually offset openings of the pressure piece engage and that Preferably made of drawn sheet metal pressure piece held by the tongues will. Because the ends of the tongues are particularly stressed in this construction the wear of the tongue tips will increase due to the much greater hardness these places are reduced.
In der Zeichnung ist der Gegenstand der Erfindung am Beispiel einer Zungentellerfederdargestellt.In the drawing, the subject matter of the invention is exemplified by one Tongue disc spring shown.
Fig. 1 zeigt eine Ansicht auf ,die Federplatte einer Kupplung; Fig.2 einen Axialschnitt mit schematisch dargestellter Anlaufscheibe. Die Tellerfeder 1 besitzt an sich bekannte Zungen 2, deren Enden 3 gegen eine Anlaufscheibe 4 anliegen.Fig. 1 shows a view of the spring plate of a clutch; 2 shows an axial section with the thrust washer shown schematically. The plate spring 1 has tongues 2 known per se, the ends 3 of which bear against a thrust washer 4.
Die Anlaufscheibe 4 ist mit dem axialbeweglichen Ausrücken der Kupplung verbunden. Beire Durchdrücken des Ausrückers übt ,die Anl.ajufscheibe 4, an welcher die Enden 3 der Tellerfederzungendauernd anliegen, :einen Druck in axialer Richtung aus. Dabei liegen, wie Fig. 2 zeigt, die Enden 3 der Tellerfederzungen dauernd gegen die Anlaufscheibe 4 oder ein sonstiges Druckstück schleifend an und sind stark auf Verschleiß beansprucht. Die bisherige starke Abnutzung wird durch :die mit der vorgesehenen Härtung erzielbaren Erhöhung der Verschleißfestigkeit der Enden 3 vermieden.The thrust washer 4 is connected to the axially movable disengagement of the clutch. When the releaser is pushed through, the stop disc 4, on which the ends 3 of the disc spring tongues are permanently in contact, exerts pressure in the axial direction. Here, as FIG. 2 shows, the ends 3 of the plate spring tongues are constantly rubbing against the thrust washer 4 or some other pressure piece and are subject to heavy wear. The previous heavy wear is avoided by: the increase in the wear resistance of the ends 3 that can be achieved with the intended hardening.
