Abstract
Description
Die Erfindung betrifft eine elektromagnetische Federdruckbremse oder -kupplung mit einer – relativ zu einer Bremsen- oder Kupplungsdrehachse – axial verlagerbaren Brems- oder Kupplungsscheibe, die drehschlüssig mit einem Bremsen- oder Kupplungsteil verbunden ist.The invention relates to an electromagnetic spring pressure brake or clutch with a - relative to a brake or clutch rotational axis - axially displaceable brake or clutch disc, which is rotationally connected to a brake or coupling part.
Einer derartige elektromagnetische Federdruckbremse oder -kupplung ist allgemein bekannt. Die bekannte Bremse oder Kupplung weist einen mit einer elektromagnetischen Spule versehenen Spulenkörper mit einer axial verlagerbaren Ankerscheibe auf. Auf die Ankerscheibe wirken mehrere, über den Umfang der Ankerscheibe verteilt angeordnete Schraubendruckfedern, um die Ankerscheibe gegen eine ebenfalls begrenzt axial verlagerbare Brems- oder Kupplungsscheibe zu pressen. Ein axial fester Brems- oder Kupplungsflansch begrenzt die axiale Beweglichkeit der Brems- oder Kupplungsscheibe, wobei eine durch die Schraubendruckfedern bewirkte Axialverlagerung der Ankerscheibe dazu führt, dass die Ankerscheibe die Brems- oder Kupplungsscheibe gegen den Brems- oder Kupplungsflansch presst und so die gewünschte Bremswirkung oder Drehmomentübertragung erzielt. Die bekannte Federdruckbremse oder -kupplung weist eine im Funktionszustand etwa horizontale Bremsen- oder Kupplungsdrehachse auf.Such an electromagnetic spring pressure brake or clutch is well known. The known brake or clutch has a coil body provided with an electromagnetic coil with an axially displaceable armature disk. On the armature disk act more distributed over the circumference of the armature disk arranged helical compression springs to press the armature disk against a likewise axially displaceable limited brake or clutch disc. An axially fixed brake or coupling flange limits the axial mobility of the brake or clutch disc, wherein caused by the helical compression axial displacement of the armature disc causes the armature disc presses the brake or clutch disc against the brake or coupling flange and so the desired braking effect or Torque transmission achieved. The known spring-pressure brake or clutch has an approximately horizontal brake or clutch rotational axis in the functional state.
Aufgabe der Erfindung ist es, eine elektromagnetische Federdruckbremse oder -kupplung der eingangs genannten Art zu schaffen, die auch bei einem Einbau mit senkrecht ausgerichteter Bremsen- oder Kupplungsdrehachse eine einwandfreie Funktion ermöglicht.The object of the invention is to provide an electromagnetic spring pressure brake or clutch of the type mentioned, which allows proper operation even with an installation with vertically aligned brake or coupling axis of rotation.
Diese Aufgabe wird dadurch gelöst, dass ein Stützring koaxial zu der Bremsen- oder Kupplungsdrehachse an dem Bremsen- oder Kupplungsteil angeordnet ist, auf dem die Brems- oder Kupplungsscheibe bei senkrechtem Einbau der Federdruckbremse oder -kupplung aufliegt. Durch die erfindungsgemäße Lösung ist es möglich, die Federdruckbremse oder -kupplung sowohl in horizontaler Ausrichtung als auch in vertikaler Ausrichtung zu betreiben. Der Stützring gewährleistet, dass bei vertikalem, d. h. senkrechtem Bremsen- oder Kupplungseinbau die Brems- oder Kupplungsscheibe nicht permanent auf dem axial benachbarten Bremsen- oder Kupplungsabschnitt wie insbesondere einer Ankerscheibe aufliegt. Durch den Stützring bleibt die Brems- oder Kupplungsscheibe auch bei senkrechtem Einbau zu dem benachbarten Brems- oder Kupplungsabschnitt wie insbesondere der Ankerscheibe oder einem Brems- oder Kupplungsflansch beabstandet.This object is achieved in that a support ring is arranged coaxially to the brake or coupling axis of rotation on the brake or coupling part on which rests the brake or clutch disc with vertical installation of the spring pressure brake or clutch. The solution according to the invention makes it possible to operate the spring-pressure brake or clutch both in horizontal alignment and in vertical alignment. The support ring ensures that when vertical, d. H. vertical brake or clutch installation, the brake or clutch disc does not permanently rests on the axially adjacent brake or clutch portion such as in particular an armature disc. By the support ring, the brake or clutch disc remains even with vertical installation to the adjacent brake or clutch section such as in particular the armature disc or a brake or clutch flange spaced.
In bevorzugter Weise ist der Bremsen- oder Kupplungsteil eine innenliegende Bremsen- oder Kupplungsnabe, auf der die Brems- oder Kupplungsscheibe koaxial aufsitzt und mittels entsprechender Axialverzahnungen längs der Brems- oder Kupplungsnabe verschiebbar ist.Preferably, the brake or coupling part is an internal brake or clutch hub on which the brake or clutch disc is seated coaxially and by means of corresponding axial toothing along the brake or clutch hub is displaceable.
In Ausgestaltung der Erfindung ist der Stützring axial verlagerbar gelagert und in einer axialen Stützrichtung mit einer Federkraft beaufschlagt, die wenigstens dem Betrag der Gewichtskraft der Brems oder Kupplungsscheibe entspricht. Dadurch kann der Stützring die Brems- oder Kupplungsscheibe bei senkrechtem Einbau der Bremse oder Kupplung tragen. Vorzugsweise ist die Federkraft derart auf den Betrag der Gewichtskraft der Brems- oder Kupplungsscheibe abgestimmt, dass die Federkraft bei senkrechtem Bremseneinbau die Brems- oder Kupplungsscheibe im Gleichgewicht hält. Die Federkraft wird durch eine Federanordnung aufgebracht, die vorzugsweise mehrere, über den Umfang des Bremsen- oder Kupplungsteiles verteilt angeordnete Schraubendruckfedern umfasst.In an embodiment of the invention, the support ring is mounted axially displaceable and acted upon in an axial support direction with a spring force corresponding to at least the amount of weight of the brake or clutch disc. This allows the support ring to wear the brake or clutch disc with vertical installation of the brake or clutch. Preferably, the spring force is adjusted to the amount of weight of the brake or clutch disc such that the spring force keeps the brake or clutch disc in balance with normal brake installation. The spring force is applied by a spring arrangement, which preferably comprises a plurality of distributed over the circumference of the brake or coupling part arranged helical compression springs.
In weiterer Ausgestaltung der Erfindung sind dem Stützring insbesondere manuell bedienbare Stellmittel zugeordnet, die den Stützring zwischen einer Ruhestellung für einen waagrechten Einbau der Federdruckbremse oder -kupplung und einer Funktionsstellung für einen senkrechten Einbau der Federdruckbremse oder -kupplung verlagern. Bei waagrechtem Einbau wird der Stützring durch die Stellmittel in seine Ruhestellung überführt und in dieser Ruhestellung arretiert gehalten, um die freie Axialbeweglichkeit der Brems- oder Kupplungsscheibe nicht zu behindern. Die Stellmittel weisen sowohl Verstell- als auch Arretierungsfunktion für den Stützring auf. In der Funktionsstellung geben die Stellmittel den Stützring frei, so dass er insbesondere durch Federkraft in seine die Brems- oder Kupplungsscheibe im Gleichgewicht haltende Funktionsstellung beweglich ist. Die Stellmittel wirken. bei der Überführung des Stützringes aus der Funktionsstellung in die Ruhestellung gegen die Federkraft, so dass eine entsprechende Federanordnung in der Ruhestellung des Stützringes vorgespannt ist und durch die Arretierfunktion der Stellmittel in dieser vorgespannten Stellung gehalten wird.In a further embodiment of the invention, the support ring in particular manually operable actuating means are assigned to shift the support ring between a rest position for a horizontal installation of the spring pressure brake or clutch and a functional position for a vertical installation of the spring pressure brake or clutch. When mounted horizontally, the support ring is transferred by the adjusting means in its rest position and locked in this rest position, so as not to hinder the free Axialbeweglichkeit the brake or clutch disc. The adjusting means have both adjustment and locking function for the support ring. In the functional position, the adjusting means release the support ring so that it can be moved, in particular by spring force, into its functional position holding the brake or clutch disc in equilibrium. The actuating means act. in the transfer of the support ring from the functional position in the rest position against the spring force, so that a corresponding spring arrangement is biased in the rest position of the support ring and is held by the locking function of the actuating means in this biased position.
Weitere Vorteile und Merkmale der Erfindung ergeben sich aus den Ansprüchen sowie aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels der Erfindung, das anhand der Zeichnungen dargestellt ist.Further advantages and features of the invention will become apparent from the claims and from the following description of a preferred embodiment of the invention, which is illustrated by the drawings.
