Description

Gewellte Ringscheibenfeder mit radial gerichteten Wellenbergen und -tälern zum Lösen der Lamellen von Lamellenkupplungen Die Erfindung betrifft eine gewellte Ringscheibenfeder mit radial gerichteten Wellenbergen und -tälern zum Lösen der Lamellen von Lamellenkupplungen. Solche Ringscheibenfedern sind an sich bekannt. Bei den bekannten Ringscheibenfedern liegen die Erzeugenden der flach oder konisch ausgebildeten Scheiben in parallelen Ebenen oder auf einem gewellten Kegelmantel. Beim Zusammendrücken der Scheiben wird das Material rein auf Biegung beansprucht. Um erhebliche Federkräfte zu erzielen, müssen die Wellen ein erhebliches Ausmaß haben, weswegen Spalte zwischen den Lamellen der Kupplungen verhältnismäßig breit sein müssen. Die Federn müssen zudem, aus ausreichende Federkräfte zu erzielen, gehärtet sein.Wavy washer spring with radially directed wave crests and valleys for releasing the discs of multi-disc clutches The invention relates to a Corrugated disc spring with radially directed wave crests and valleys for loosening of the disks of multi-disk clutches. Such annular disk springs are known per se. In the known disc springs, the generatrices are flat or conical formed disks in parallel planes or on a corrugated cone surface. When the panes are pressed together, the material is subjected to bending stresses. In order to achieve significant spring forces, the waves must be of a considerable size have, which is why gaps between the plates of the clutches are relatively wide must be. The springs must also achieve sufficient spring forces, be hardened.

Die Erfindung schafft eine Verbesserung und Vereinfachung der Federn, indem erfindungsgemäß den Wellenbergen am äußeren Umfang der Feder Wellentäler am inneren Umfang der Feder gegenüberliegen, und umgekehrt. Die Erzeugende einer solchen Federfläche führt, über den gesamten Umfang der Feder betrachtet, Winkelbewegungen etwa um den Mittelkreis der Ringscheibenfeder aus. Hierdurch wird eine Feder geschaffen, die lediglich auf Torsion beim Zusammendrücken beansprucht wird und die auch in sehr engen Spalten zwischen den Lamellen von Kupplungen verwendbar ist. Die Federkraft ist auch bei nur geringer Zusammendrückung verhältnismäßig hoch. Da das Material nur geringfügig deformiert wird, braucht eine solche Feder nicht gehärtet zu werden. Das Stanzen der Feder kann gemeinsam mit der Formung der Feder in einem einzigen Werkzeug erfolgen, und damit wird die Herstellung einer solchen Feder außerordentlich wirtschaftlich.The invention creates an improvement and simplification of the springs, according to the invention by the wave crests on the outer circumference of the spring wave troughs on opposite inner circumference of the spring, and vice versa. The producer of such a When viewed over the entire circumference of the spring, the spring surface leads to angular movements around the center circle of the annular disc spring. This creates a spring which is only subjected to torsion when compressed and which is also in very narrow gaps between the plates of clutches can be used. The spring force is relatively high even with only slight compression. Because the material is only slightly deformed, such a spring does not need to be hardened. The stamping of the spring can be combined with the molding of the spring in a single Tool made, and thus the manufacture of such a spring is extraordinary economically.

Die Erfindung wird nachstehend in einem Ausführungsbeispiel an Hand der Zeichnung näher erläutert.The invention is illustrated below in an exemplary embodiment the drawing explained in more detail.

Fig. 1 zeigt einen Axialschnitt durch einen Teil einer Lamellenkupplung, die in einer vollständig mit Flüssigkeit gefüllten Kammer arbeitet; Fig. 2 zeigt das Kantenprofil eines Federteiles gemäß der Erfindung in eine Ebene projiziert; Fig. 3 zeigt eine schaubildliche Darstellung eines Teiles der Feder.Fig. 1 shows an axial section through part of a multi-plate clutch, which works in a chamber completely filled with liquid; Fig. 2 shows projected the edge profile of a spring part according to the invention into a plane; Fig. 3 shows a diagrammatic representation of part of the spring.

Die Ausführung einer Lamellenkupplung, wie sie dargestellt ist, kann z. B. bei einem hydraulischen, nicht dargestellten Drehmomentwandler verwendet werden. Die Arbeitskammer des Drehmomentwandlers ist mit 10 bezeichnet. Sie steht mit der vollständig mit Flüssigkeit gefüllten Kammer 13 der Lamellenkupplung 12 über das Lager 14 in Verbindung. Das Gehäuse 16 der Primärseite der Kupplung ist mit einem durch Druckflüssigkeit betätigten Kolben 18 versehen. Dieser dient zum Zusammendrücken von Lamellen 20, 21, 22, 23 der Primärseite mit den Lamellen 24, 25, 26 der Sekundärseite gegen die Rückwand 12 der Kupplung entgegen der Wirkung einer Bellevillefeder 33. Die Lamellen sind in Keilnuten 28 und 30 des Kupplungsgehäuses 16 und einer Nabe 35 axial beweglich.The execution of a multi-plate clutch, as shown, can z. B. be used in a hydraulic torque converter, not shown. The working chamber of the torque converter is denoted by 10. She stands with the Completely filled with liquid chamber 13 of the multi-plate clutch 12 via the Bearing 14 in connection. The housing 16 of the primary side of the clutch is with a piston 18 actuated by pressure fluid is provided. This is used to compress of slats 20, 21, 22, 23 of the primary side with the slats 24, 25, 26 of the secondary side against the rear wall 12 of the coupling against the action of a Belleville spring 33. The plates are in keyways 28 and 30 of the clutch housing 16 and a hub 35 axially movable.

Um nun die Lamellen der Sekundärseite der Kupplung bei freier Drehung in ausreichendem Abstand zu halten, derart, daß die Lamellen der Primärseite nicht in Anlage sind, sind Ringscheibenfedern 32 zwischen den Scheiben 24, 25 und 26 vorgesehen. Die Form dieser Ringscheibenfedern ergibt sich im einzelnen aus den Fig. 2 und 3. Hier ist ein Teil einer Ringscheibenfeder 32 mit inneren Zähnen 34 dargestellt, die die Ringscheibenfedern in den Keilnuten 30 führen. Der innere und äußere Umfang der Ringscheibenfeder bilden abwechselnd Wellenberge 36 und Wellentäler 38. Wird die Ringscheibenfeder axial zwischen den Lamellen der Sekundärseite zusammengepreßt, so werden die verwundenen Teile in Richtung auf die Hauptebene der Ringscheibenfeder zu verdreht. Da nun die Federkraft durch Torsion erzeugt wird, so wird eine große Federkraft im Vergleich zu den früher benutzten Federn bei sehr geringen Zusammendrückung (einige zehntel Millimeter) erzielt.Now around the lamellae of the secondary side of the clutch when rotating freely to keep at a sufficient distance, so that the lamellas of the primary side not are in contact, annular disk springs 32 are provided between the disks 24, 25 and 26. The shape of these annular disc springs can be seen in detail from FIGS. 2 and 3. Here a part of an annular disc spring 32 with internal teeth 34 is shown, which guide the annular disc springs in the keyways 30. The inner and outer perimeter of the annular disk spring alternately form wave crests 36 and wave troughs 38 the annular disc spring is axially compressed between the lamellae on the secondary side, so are the twisted parts towards the main plane of the washer spring too twisted. Since the spring force is now generated by torsion, it becomes large Spring force compared to the springs used earlier at very low Compression (a few tenths of a millimeter) achieved.
