ElektromagnetElectromagnet

Elektromagneten verursachen, wenn sie beispielsweise für J elektromagnetische Kupplungen oder Bremsen verwendet werden, i beim Lüften der Kupplung oder Bremse ein starkes Anzugs- J geräusch durch das Aufprallen des Magnetankere auf den die Spulen tragenden Magnetkern. Dies wirkt sich vor allem bei Bremsmotoren nachteilig aus, für die ein leises Schaltverhalten gewünscht wird.Cause electromagnets when electromagnetic, for example, J clutches or brakes used, i for releasing the clutch or brake a strong tightening J noise by the impact of the magnetic Ankere on the bobbin-carrying magnetic core. This has a disadvantageous effect, especially in the case of brake motors for which quiet switching behavior is desired.

Die Neuerung beseitigt diesen lachteil dadurch, daß zwischen dem Magnetkern und dem Magnetanker wenigstens ein schalldämpfendes Element aus Kunststoff oder ähnlichem geeignetem Material vorgesehen ist. Zweckmäßig besteht das Element aus eine- Kunststoffolie, die leicht in einem Restluftspalt zwischen Magnetkörper und Anker unterbringbar ist.The innovation eliminates this disadvantageous part by having at least one sound-absorbing element between the magnetic core and the armature Element made of plastic or similar suitable material is provided. The element expediently consists of a plastic film that easily fits into a residual air gap can be accommodated between the magnet body and armature.

Die Zeichnung zeigt ein Ausführungsbeispiel der Neuerung an Hand einer elektromotorischen Bremse. In einem Gehäuse ist der die Spulen 2 enthaltende Magnetkern 3 untergebracht, dem der Magnetanker 4 gegenübersteht. Dieser Magnetanker sitzt in bekannter Weise axial beweglich auf Bolzen 5 und steht unter der Wirkung von Bremsdruckfedern 6. Zwischen dem Magnetanker 4 und einer Bremsfläche 7 ist die umlaufende Bremsscheibe 8 angeordnet, die beidseitig mit Bremsbelägen 9 und 10 versehen ist*The drawing shows an embodiment of the innovation using an electromotive brake. In one housing the magnet core 3 containing the coils 2 is accommodated, which the magnet armature 4 faces. This magnet anchor sits axially movably on bolt 5 in a known manner and is under the action of brake pressure springs 6. Between the armature 4 and a braking surface 7, the rotating brake disk 8 is arranged, which is on both sides is provided with brake pads 9 and 10 *

Gemäß der Neuerung ist nun in einem Luftspalt zwischen dem Magnetkern 3 und dem Anker 4 eine Kunststoffolie 11 ange-According to the innovation is now in an air gap between the Magnet core 3 and the armature 4 a plastic film 11 attached.

ordnet, beispielsweise an des Ma^nttkern 3 «neelclebt. B«ia Lüften der Bremse schlägt der Inker 4 nicht unmittelbar gegen den Bisenkörper 3 an, sondern gegen Ale Folie 11 , wodurch das Aneugegeräusch stark herabgesetzt wird. Sas Geräusch bei« Einfallen der Bremse wird ohnehin durch den Bremsbelag gedämpft. arranges, for example, at the core of the master. In general, when the brake is released, the inker 4 does not strike directly against the bite body 3 , but against a sheet 11, which greatly reduces the leaning noise. The noise when the brake is applied is muffled by the brake lining anyway.
