Description
Lamellenkupplungen sind an sich. bekannt.- Beim Abschaltender Kupplung kleben häufig die einzelnen Lamellen aneinander, wodurch im Leerlauf die Leistungsaufnahme vergrößert wird, so daß derartige Kupplungen z. B. für automatische Regelung häufig nicht verwendbar sind. Man hat hiergegen vorgeschlagen, die Lamellen wellenförmig federnd auszubilden und hat dadurch auch ein besseres Lösen der einzelnen Lamellen voneinander erreicht. Die Herstellung solcher Lamellen ist aber teuer, und zum Einkuppeln werden verhältnismäßig große Kräfte benötigt.Multi-plate clutches are in themselves. known - when the clutch is switched off The individual slats often stick together, which reduces power consumption when idling is enlarged so that such couplings z. B. for automatic control often are not usable. Against this, it has been proposed that the lamellae be wave-shaped to be resilient and thus also has a better loosening of the individual lamellae reached from each other. The production of such slats is expensive, and for coupling relatively large forces are required.
Die Erfindung betrifft eine Lamellenkupplung mit ebenen Lamellen und hat zur Aufgabe, diese Lamellen so auszubilden, daß sich diese beim Lösen der Kupplung sicher und leicht voneinander trennen. . -Das wird bei der Lamellenkupplung nach der Erfindung durch die Verwendung magnetischer Kräfte erreicht, die bei Ausschalten der Kupplung unter Überwindung der Haftkräfte die Lamellen sicher voneinander lösen. Am zweckmäßigsten ist es hierbei, die einzelnen Lamellenscheiben als Permamentmagnete auszubilden, und zwar in solcher Anordnung, daß sich die aufeinanderfolgenden Lamellen gegenseitig abstoßen. Sind die Lamellen mit Bremsbelägen versehen, so läßt sich die Erfindung dadurch verwirklichen, daß in an sich bekannter Weise den Bremsbelägen Magnetpulver beigemischt wird.The invention relates to a multi-disc clutch with flat discs and has the task of designing these lamellae in such a way that they move when the clutch is released separate from each other safely and easily. . -That will be the case with the multi-plate clutch of the invention achieved through the use of magnetic forces when switched off the clutch, while overcoming the adhesive forces, safely detach the lamellae from one another. It is most useful here to use the individual flap discs as permanent magnets form, in such an arrangement that the successive lamellae repel each other. If the lamellae are provided with brake pads, it can be realize the invention in that the brake linings in a manner known per se Magnet powder is added.
An Hand der Zeichnung wird ein Ausführungsbeispiel einer Lamellenkupplung nach der Erfindung näher erläutert: Die Zeichnung zeigt eine Prinzipskizze, bei der auf einer treibenden Welle z Lamellen 2 aus magnetisch nicht leitendem Material mitgenommen werden. Die Abtriebswelle 3 trägt in ihrem zylindrischen Ansatz 4 die Gegenlamellen 5, die mit Bremsbelägen versehen sind, denen Magnetpulver beigemischt ist. Diese sind so magnetisiert, daß sich zwei aufeinanderfolgende Gegenlamellen magnetisch abstoßen. Mit N und S sind die Nord-und Südpole der Lamellenmagnete eingetragen.. Hierbei brauchen die magnetischen Kräfte der Permanentmagnete nur so groß zu sein, daß sie die Haftkräfte der Lamellen überwinden können. Möglich ist auch die Anordnung von Elektromagneten, die zwar teurer sind, dafür aber nur im Zeitpunkt des Lösens der Kupplung eingeschaltet zu werden brauchen.An exemplary embodiment of a multi-plate clutch is shown with reference to the drawing explained in more detail according to the invention: The drawing shows a schematic diagram in on a driving shaft z lamellae 2 made of magnetically non-conductive material get picked up. The output shaft 3 carries in its cylindrical extension 4 the Counter lamellae 5, which are provided with brake linings to which magnetic powder is added is. These are magnetized in such a way that there are two consecutive counter lamellae repel magnetically. The north and south poles of the lamella magnets are entered with N and S .. The magnetic forces of the permanent magnets only need to be so great that that they can overcome the adhesive forces of the slats. The arrangement is also possible of electromagnets, which are more expensive, but only when they are released the clutch need to be switched on.
