Description
Die bekannten mechanischen elektrischen oder elektromagnetischen Bremsen haben den. Nachteil, daß sie für ganz kurzzeitige präzise Bremsung nicht geeignet sind, weil ihre Wir-' kung nicht momentan und nicht rasch genug einsetzt, wobei überdies durch die zumeist große Masse des abzubremsenden Teiles die Schnelligkeit der Bremswirkung herabgemindert wird. Während die rein mechanischeThe known mechanical electrical or electromagnetic brakes have the. Disadvantage that they are not suitable for very short-term precise braking because their we- ' kung does not start momentarily and not quickly enough, and moreover by mostly large mass of the part to be braked reduces the speed of the braking effect will. While the purely mechanical
ίο Bremse an sich den Mangel hat, insbesondere nicht für dauernde kurzzeitige Bremsung geeignet zu sein, hat die elektrische oder elektromagnetische Bremse an sich entweder den Nachteil, nicht rasch genug 'zu wirken oder zu versagen, wenn aus irgendeinem Grunde der Strom ausbleibt. Alle diese Bremsen versagen, wenn die Bremswirkung in Bruchteilen von Sekunden einsetzen muß und sehr häufig aufeinander folgen soll.ίο brake itself has the defect, in particular The electrical or electromagnetic brakes have to be unsuitable for permanent short-term braking Brake itself either has the disadvantage of not acting quickly enough or fail if for any reason the power fails. All these brakes fail when the braking effect has to start in fractions of a second and should follow one another very often.
Diese Übelstände werden gemäß der Erfindung durch eine Federbremse mit elektromagnetischer Lüftung beseitigt.These drawbacks are according to the invention by a spring brake with electromagnetic Removed ventilation.
Federbremsen mit elektromagnetischer Lüftung sind an sich bekannt. Von den bekann- · ten Federbremsen, bei welchen die auf der abzubremsenden Welle sitzende Bremsscheibe zwischen zwei Reiborganen liegt, von welchen das eine mit der Ankerscheibe und das andere mit dem Magnetkörper verbunden ist, unter-,Spring brakes with electromagnetic ventilation are known per se. From the well-known th spring brakes, in which the brake disc sitting on the shaft to be braked lies between two friction organs, one of which with the armature disk and the other is connected to the magnet body, under-,
30' scheidet sich der Erfindungsgegenstand dadurch, daß beide Magnetteile achsial verschiebbar gelagert und unter den Druck entgegengesetzt wirkender Federn verschiedener Stärke gesetzt sind, von welchen die stärkere "die Bremsfeder ist. Durch elektromagnetischen Anzug wird die Bremsfeder unter einseitiger Entlastung der Bremsscheibe wirkungslos gemacht und dadurch die schwächere Feder ausgelöst, welche infolge der achsialen Verschiebbarkeit jedes der beiden Magnetteile die Bremsscheibe gleichzeitig auch von der anderen Seite zwangläufig entlastet, wodurch augenblicklich die Bremsscheibe, frei läuft. Bei Lösung der Kupplung durch Unterbrechen der Erregung werden durch die Bremsfeder unter der mit einer achsialen Verschiebung beider Kupplungsteile gegen die Bremsscheibe zu verbundinen Überwindung der schwächeren Feder die Reiborgane gleichzeitig von beiden Seiten zwangläufig und vollkommen gleich stark an die Bremsscheibe angedrückt und dadurch augenblicklich Bremsung hervorgerufen.'30 'the subject matter of the invention is divided by that both magnet parts are axially displaceable and opposed under the pressure acting springs of different strength are set, of which the stronger "the Brake spring is. Electromagnetic tightening causes the brake spring to become unilateral Relief of the brake disc made ineffective and thereby triggered the weaker spring, which, due to the axial displaceability of each of the two magnetic parts, the brake disc at the same time inevitably relieved from the other side, which means instantly the brake disc, runs freely. When the clutch is released by interrupting the excitation are caused by the brake spring under the with an axial displacement of both clutch parts against the brake disc to verbundinen overcoming the weaker spring, the friction elements at the same time inevitably from both sides and pressed against the brake disc with the same force and therefore instantly Braking caused. '
In der Zeichnung ist eine beispielsweise Ausführungsform des Erfindungsgegenstandes ' veranschaulicht. " 'The drawing shows an example embodiment of the subject matter of the invention ' illustrated. "'
A ist die Bremsscheibe, welche mit der abzubremsenden Welle fest und unverrückbar verbunden und zweckmäßig möglichst dünn bzw. leicht gemacht ist. B, B1 sind die Reibkörper, welche durch Federkraft an die Bremsscheibe A angepreßt und durch elektromagnetischen Anzug einer Ankerscheibe C an einen · Magnetkörper D gelüftet werden.. Bei der ver- · anschaulichten· Ausführungsform ist der eine Reibkörper B mit dem 'Magnetkörper D und der andere Reibkörper B1 mit der Anker- ·, v scheibe C verbunden und die Bremsfedern F zwischen der Ankerscheibe und dem Magnetkörper angeordnet. Im Magnetkörper D ist die Wicklung G angeordnet, deren Ende zu ,zwei Klemmen führen, welche mit einem Schalter in Verbindung stehen. A is the brake disc which is firmly and immovably connected to the shaft to be braked and which is expediently made as thin or light as possible. B, B 1 are the friction bodies which are pressed against the brake disk A by spring force and are released by electromagnetic attraction of an armature disk C to a magnet body D. In the illustrated embodiment, the one friction body B with the magnet body D is and the other friction body B 1 is connected to the armature ·, v disk C and the brake springs F are arranged between the armature disk and the magnet body. In the magnet body D , the winding G is arranged, the end of which leads to two terminals, which are connected to a switch.
