Description
Elektromagnetische Scheibenbremse Die Erfindung betrifft eine elektromagnetische Scheibenbremse, bei dercder Magnetanker umläuft und mit einem Bremsbelag versehen ist, also gleichzeitig die Bremsscheibe bildet. Bisher waren für derartige Bremsen Bremsdruckfedern oder Abhebefedern notwendig, die nach einer gewissen Abnutzung des Bremsbelages nachgestellt werden mußten. Die Erfindung stellt sich die Aufgabe, eine einfachere Bremsenausführung zu schaffen, bei der keine Druckfedern mehr notwendig sind.Electromagnetic Disc Brake The invention relates to an electromagnetic disc brake Disc brake in which the magnet armature revolves and is provided with a brake lining is, so at the same time forms the brake disc. Previously were for such brakes Brake pressure springs or lift-off springs are necessary after a certain amount of wear of the brake lining had to be readjusted. The invention has the task of to create a simpler brake design that no longer requires compression springs are.
Dies wird'erfindungsgemäß durch eine federnde Aufhängung und/ oder Ausbildung der Ankerscheibe erreicht. Eine federnde Aufhängung kann zweckmäßig darin bestehen, daß die Ankerscheibe klemmend auf einer unrunden, vorzugsweise vieleckigen Nebe sitzt, die mit einer Manschette aus elastischem Werkstoff, wie Gummi, Kunststoff od. dgl., überzogen ist. Der Bremsbelag ist auf der dem Magneten zugewandten Seite der Ankerscheibe angeordnest, und bei Erregung der Magnetspulen wird die Scheibe mit dem Bremsbelag angezogen, wobei sich die erwännte Manschette nachgebend verformt. Bei Abschaltung deß Magneten nimmt die Manschette wieder ihre ursprüngliche Gestalt an und bringt die Ankerscheibe in die Ruhestellung. Außer dem Wegfall von Bremsdruckfedern ergibt sich noch der Vorteilieiner selbsttätigen Nachstellung bei Abnutzung des Bremsbeljges. Wird nach einer sol chen Abnutzung der Luftspalt wisch Magnet und Ankerscheibe größer als Vorgesehen, dann rutschtrdie Ankerscheibe unter dem Einfluß derzMagnetz.ugk.raft auf der Itanschette nach und der Luftspalt wird wieder verringert.According to the invention, this is achieved by a resilient suspension and / or Reached training of the armature disk. A resilient suspension can be useful in it exist that the armature disk is clamped on a non-circular, preferably polygonal Nebe sits with a sleeve made of elastic material, such as rubber, plastic or the like, is coated. The brake lining is on the side facing the magnet the armature disk, and when the magnet coils are excited, the disk becomes tightened with the brake lining, whereby the mentioned sleeve deforms yielding. When the magnet is switched off, the sleeve returns to its original shape and brings the armature disk into the rest position. Except for the elimination of brake pressure springs there is still the advantage of an automatic adjustment when the Brake pads. After such wear and tear, the air gap will wipe the magnet and Armature disk larger than intended, then the armature disk slips under the influence derzMagnetz.ugk.kraft on the Itan collar and the air gap is reduced again.
Eine andere Ausführung besteht darin, die Ankerscheibe selbst federnd so auszubilden, daß sie von der Magnetzugkraft verformt und angezogen wird.Another design consists in making the armature disk itself resilient to be trained so that it is deformed and attracted by the magnetic pull.
An Hand der Zeichnung sind einige Ausführungsbeispiele der erfindungsgemäßen Bremse beschrieben.With reference to the drawing are some embodiments of the invention Brake described.
In den Fig. 1 und 2 ist auf einer Welle 1 eine achteckige Nabe 2 befestigt. Diese Nabe ist mit einer Kunststoffmanschette 3 überzogen, auf der klemmend die Magnetankerscheibe 4 sitzt. Die Scheibe 4 trägt einen Bremsbelag 5, der dem feststehenden Magneten zugewandt ist. Wird der Magnet erregt, dann zieht dieser die Scheibe 4 mit dem Bremsbelag 5 an, wobei die elastische Manschette 3 sich etwas verformt. Nach Ausschalten des Magneten nimmt die Manschette 3 durch ihre Elastizität wieder die ursprüngliche Gestalt an, wobei die Scheibe 4 in die Ruhestellung gebracht wird.In FIGS. 1 and 2, an octagonal hub 2 is attached to a shaft 1. This hub is covered with a plastic sleeve 3 on which the clamping Magnet armature disk 4 is seated. The disc 4 carries a brake lining 5, which is the fixed Facing magnet. If the magnet is excited, it pulls the disk 4 with the brake lining 5, the elastic sleeve 3 being slightly deformed. After switching off the magnet, the cuff 3 resumes due to its elasticity the original shape, the disc 4 is brought into the rest position.
Wird nach einem bestimmten Verschleiß des Bremsbelages 5 der Luftspalt zwischen Magnet und Scheibe 4 größer, dann erfolgt ein selbsttätiges Nachstellen der Scheibe, indem diese unter der Wirkung der Magnetzugkraft auf der Manschette nachrutscht.After a certain amount of wear on the brake lining 5, the air gap becomes between magnet and disk 4 is larger, then an automatic readjustment takes place of the disc by moving it under the action of magnetic pull on the cuff slips.
In den- Fig. 3 und 4 besteht die Ankerscheibe 6 aus elastischem Stahlblech und ist mit sternförmigen Zungen 7 versehen. Die Zungen tragen aX ihrem äußeren Ende einen ringförmigen Bremsbelagträger 8. Die Scheibe 6 hat eine hohlzylindrische Nabe 9, die über Kunststoffringe 10 oder Ringspannelemente 11 auf der Welle 12 gelagert ist. Bei Erregung des Magneten geben die Zungen 7 der Ankerscheibe 6 nach, und der Ring 8 wird gegen die Bremsfläche gezogen. Nach Abschalten des Magneten federn die Zungen 7 in ihrq Ruhelage zurück und nehmen den Bremsring 8 mit. Ist der BrEmsbelag bis zu einem gewissen Grad abgenutzt, dann rutscht dif Nabe 9 auf den Kunststo-ffringen 10 bzw. den Ringepannelementen 11 nach, so daß der vbrbestimmte Luftspalt wieder eingehalisn wird.In FIGS. 3 and 4, the armature disk 6 consists of elastic sheet steel and is provided with star-shaped tongues 7. The tongues bear aX their outer one End of an annular brake lining carrier 8. The disc 6 has a hollow cylindrical Hub 9, which is mounted on the shaft 12 via plastic rings 10 or ring clamping elements 11 is. When the magnet is excited, the tongues 7 of the armature disk 6 give way, and the Ring 8 is pulled against the braking surface. After switching off the magnet, the springs Tongues 7 back in their rest position and take the brake ring 8 with them. Is the brake lining worn to a certain extent, then the dif hub 9 slips on the plastic rings 10 or the ring tensioning elements 11 after, so that the predetermined air gap again is held.
Wie in Fig. 5 dargestellt, kann dte Ankerscheib. 6 auch abnehm- t bar an einer gesonderten Nabe 13 sitzen, wodurch das Auswechseln des Bremsbelages erleichtert wird. Das gleiche gilt für den Bremsbelagträger 8, der ebenfalls abnehmbar mittels Schrauben 14 an Ankerscheibe 6 befestigt sein kann (Fig. 6).As shown in Fig. 5, the armature disk. 6 also decreases bar sit on a separate hub 13, which makes it easier to change the brake lining will. The same applies to the brake pad carrier 8, which is also removable by means of Screws 14 can be attached to armature disk 6 (Fig. 6).
