Description
Elektromagnetisch betätigte Reibungskupplung Die Erfindung betrifft eine elektromagnetisch betätigte Reibungskupplung mit feststehendem Spulenkörper und davor drehbar angeordneter Ankerscheibe, die mit dem Magnetkörper einen magnetischen Kreis bildet und die zur Herstellung einer kraftschlüssigen Verbindung erforderliche Axialkraft auf das Lamellenpaket ausübt.Electromagnetically Operated Friction Clutch The invention relates to an electromagnetically operated friction clutch with a fixed spool and in front of it rotatably arranged armature disk, which with the magnetic body a magnetic Forms circle and the necessary to establish a positive connection Axial force exerts on the disk pack.
Bei einer bekanntem Ausführungsform einer solchen Kupplung ist der Magnetkörper mittels Gleitlager auf dem Kupplungskörper gelagert. Der Kraftfluß muß durch diese Lagerfläche hindurchtreten, aber auch einen weiteren Widerstand in Form eines Luftspaltes überwinden. Ferner werden bei dieser Kupplung Lamellen und Druckscheibe magnetisiert.In a known embodiment of such a coupling is the Magnet body mounted on the coupling body by means of slide bearings. The power flow must pass through this storage area, but also another resistance overcome in the form of an air gap. In addition, this clutch has lamellas and pressure disc magnetized.
Nachteilig an dieser Bauart ist die Empfindlichkeit des Gleitlagers bei höheren Drehzahlen und verschiedenen Betriebsbedingungen. Ferner können solche Kupplungen nur in Getrieben verwendet werden, da die Lamellen aus magnetisierbarem Werkstoff einer Ölschmierung bedürfen.The disadvantage of this design is the sensitivity of the plain bearing at higher speeds and different operating conditions. Furthermore, such Couplings can only be used in gearboxes because the discs are made of magnetizable Material require oil lubrication.
Bei einer weiteren. Ausführungsform ist die Ankerscheibe so ausgebildet, daß sie das Lamellenpaket umfaßt und von der Rückseite her zusammenpreßt, wenn der Kupplungsvorgang eingeleitet wird.With another. Embodiment, the armature disk is designed so that it includes the plate pack and compresses from the rear when the Coupling process is initiated.
Nachteilig an dieser Ausführung ist die schwere Ankerscheibe, die bei jedem Schaltvorgang beschleunigt werden muß und deren Gewicht verzögernd auf die Schaltgeschwindigkeit wirkt.The disadvantage of this design is the heavy armature disk, which has to be accelerated with each switching operation and its weight has to be delayed the switching speed is effective.
Bei einer ähnlichen Kupplung wird die Ankerscheibe, die auch wieder das Lamellenpaket umfaßt, gleichzeitig als Lamellenträger zur Übertragung des Drehmomentes herangezogen. Hierbei ist die hemmende Kraft während des Schaltvorganges noch größer, weil infolge der Flankenpressung an der Paßfeder eine zusätzliche Verzögerungskraft wirksam wird.With a similar coupling, the armature disk is also used again the disk pack includes, at the same time as a disk carrier for transmitting the torque used. The inhibiting force during the switching process is even greater, because due to the flank pressure on the feather key, there is an additional deceleration force takes effect.
Gegenstand der Erfindung ist eine Kupplung mit einer sehr leichten Ankerscheibe und, einem auf Wälzlagern angeordneten Spulenkörper. Es ist ferner wie bei einer Kupplung mit Schleifringen nur ein Luftspalt vorhanden. Die Kupplung kann innerhalb oder außerhalb eines Getriebekastens verwendet werden.The invention relates to a coupling with a very light one Armature disk and, a coil body arranged on roller bearings. It is further as with a coupling with slip rings, there is only one air gap. The coupling can be used inside or outside a gear box.
Die Zeichnung stellt ein Ausführungsbeispiel der Erfindung dar.The drawing shows an embodiment of the invention.
Der Magnetkörper 1 ist mittels Wälzlager auf der inneren Kupplungshälfte 2 gelagert. Dar Lamellenträger 3 besitzt eine Anzahl Finger, welche durch die an den entsprechenden Stellen genutete Ankerscheibe 4 hindurchgreifen und die Innenlamellen tragen. Auf die Ankerscheibe 4 ist die Stellmutter 5 aufgeschraubt. Auf der Rückseite ist das Lamellenpaket mittels Sprengring 6 axial gehalten. Die Außenlamellen werden in den Fingern der äußeren Kupplungshälfte 7 geführt.The magnet body 1 is on the inner coupling half by means of roller bearings 2 stored. Dar plate carrier 3 has a number of fingers, which through the on The armature disk 4 grooved in the appropriate places and the inner plates wear. The adjusting nut 5 is screwed onto the armature disk 4. On the back side the disk pack is held axially by means of snap ring 6. The outer lamellas are guided in the fingers of the outer coupling half 7.
Wird an die Spule eine Gleichspannung der vorgeschriebenen Größe gelegt, so bildet sich ein Kraftfeld, und die Ankerscheibe 4 wird angezogen. Sie preßt über die Stellmutter 5 das Lamellenpaket zusammen. Der Axialschub gleicht sich über das Kugellager 8 aus.If a DC voltage of the prescribed magnitude is applied to the coil, a force field is thus formed and the armature disk 4 is attracted. She presses over the adjusting nut 5 the lamellae together. The axial thrust is equal over that Ball bearing 8 from.
Die Feder 9 drückt die Ankerscheibe 4 gegen. den Anschlag, sobald das Kraftfeld zusammenbricht, die Kupplung also ausgeschaltet wird.The spring 9 presses the armature disk 4 against. the stop as soon as the force field collapses, so the clutch is switched off.
Damit die rotierende Ankerscheibe nicht den feststehenden Spulenkörper streifen kann, ist die Druckfeder so bemessen, daß bei Erreichung des Blockmaßes noch keine Berührung der Flächen stattfinden kann.So that the rotating armature disk does not hit the stationary coil body can touch, the compression spring is dimensioned so that when the block size is reached the surfaces cannot yet touch.
