Description

Elektromagnetisches Signalhorn, insbesondere für Kraftfahrzeuge Die Hauptpatentanmeldung W 24427 VIIId/74d betrifft ein elektromagnetisches Signalhorn, insbesondere für Kraftfahrzeuge, dessen langgestreckter, zentral an einer -.Membran befestigter Anker lediglich den Mittelpol eines periodisch erregten dreipoligen Elektromagneten beaufschlagt. Dieses Signalhorn nach der Hauptpatentanmeldung ist dadurch gekennzeichnet, daß der Anker in der Längsrichtung leicht durchgebogen ist, derart, daß seine beiden freien Enden im Winkel zu den mit den -.Mittelpolen in einer Ebene liegenden Außenpolflächen verlaufen. Mit dieser Maßnahme wird ein ungehemmtes Durchschwingen der beiden freien Enden des Ankers beim Beaufschlagen des Mittelstückes des Ankers erreicht. Um sicherzustellen, daß der gesamte Kraftfluß des Elektromagneten auf den Anker einwirkt, ist dieser nach Anspruch 2 der Hauptpatentanmeldung beidends über die Außenpole des Magneten hinaus verlängert. Der Anker gemäß der Hauptpatentanmeldung übernimmt damit die Funktion eines Mitschwingers und ersetzt diesen. -Me1St genügt jedoch das Trägheitsmoment eines solchen Ankers nicht, diese Aufgabe voll zu erfüllen, auch wenn dieser über die Außenpole hinaus verlängert ist. Einer weitergehenden Verlängerung des Ankers in der gleichen Ebene stehen sowohl die beengten Raumverhältnisse als auch mechanische Gründe entgegen.Electromagnetic horn, in particular for motor vehicles Main patent application W 24427 VIIId / 74d relates to an electromagnetic signal horn, especially for motor vehicles, whose elongated, centrally on a -.Membrane attached anchor only the center pole of a periodically excited three-pole Electromagnet applied. This horn according to the main patent application is characterized in that the anchor is slightly bent in the longitudinal direction, in such a way that its two free ends are at an angle to those with the central poles in outer pole faces lying in one plane run. With this measure becomes an uninhibited Swinging through of the two free ends of the armature when the middle section is applied reached the anchor. To ensure that the entire power flow of the electromagnet acts on the anchor, this is according to claim 2 of the main patent application at both ends extended beyond the outer poles of the magnet. The anchor according to the main patent application thus takes on the function of a co-oscillator and replaces it. -Me1St is enough However, the moment of inertia of such an armature does not fully perform this task, even if this is extended beyond the outer pole. A further one Extension of the anchor in the same level are both the cramped space conditions as well as mechanical reasons.

Hier setzt nun die Erfindung ein, indem sie die beidends verlängerten Ankerenden umbiegt. Die hierdurch erzielte Vergrößerung des Trägheitsmoments reicht in allen Fällen aus, um den Mitschwinger voll zu ersetzen. Dabei wird man den Anker derart bemessen, daß seine Eigenschwingung annähernd mit einer Eigenfrequenz (Oberton) der Membran zusaminenfällt.This is where the invention comes in by extending both ends Bends anchor ends. The increase in the moment of inertia achieved in this way is sufficient in all cases, in order to fully replace the co-oscillator. This is where you become the anchor dimensioned in such a way that its natural oscillation is approximately with a natural frequency (overtone) the membrane collapses.

Die Abbiegung der Ankerenden kann entweder zur Membran hin erfolgen. Vorzugsweise wird man jedoch diese abgebogenen Enden in den vorhandenen freien Raum zwischen Magnet und Gehäusewand hineinragen lassen.The anchor ends can either be bent towards the membrane. Preferably, however, these bent ends will be in the available free space Let it protrude between the magnet and the housing wall.

Die Zeichnung veranschaulicht in den Fig. 1 und 2 zwei Ausführungsbeispiele der Erfindung an Hand eines Schnittes durch das Signalhorn, während Fig. 3 die Ansicht des Ankers zeigt.The drawing illustrates two exemplary embodiments in FIGS. 1 and 2 of the invention on the basis of a section through the horn, while FIG. 3 shows the view of the anchor shows.

In dem Gehäuse 1 ist der Magnet 2 angeordnet, dessen Mittelteil 4 von dem Anker 3 beaufschlagt wird, ohne daß die Seitenpole 6 berührt werden. Die freien Enden 7 des verlängerten Ankers sind abgebogen, und zwar nach Fig. 1 zur Membran hin, während sie nach Fig. 2 in den freien Raum 8 zwischen Magnet und Gehäusewand hineinragen.In the housing 1, the magnet 2 is arranged, the middle part 4 is acted upon by the armature 3 without the side poles 6 being touched. the free ends 7 of the elongated armature are bent, namely according to Fig. 1 for Membrane out, while according to Fig. 2 in the free space 8 between the magnet and the housing wall protrude.
