Description

Elektromagnet, dessen zylindrischer Anker quer zu den Kraftlinien verstellbar und mit einem Ansatz versehen ist, mit dem er in einen zylindrischen Luftspalt eingreift Die Erfindung betrifft einen Elektromagneten, dessen zylindrischer Anker quer zu den Kraftlinien verstellbar und mit einem Ansatz versehen ist, mit dem er in einen zylindrischen Luftspalt eingreift. Der Querschnitt des Ansatzes oder des Spaltes oder beider Teile sind erfindungsgemäß derart gestaltet; daß der freie Spaltquerschnitt an jeder Stelle des Spaltes sich ändert, wenn der Ansatz sich bei. Axialverschiebung des Ankers zum Magneten zum Spalt verstellt.Electromagnet, whose cylindrical armature is perpendicular to the lines of force adjustable and provided with an approach with which it is in a cylindrical Air gap engages The invention relates to an electromagnet whose cylindrical Anchor is adjustable transversely to the lines of force and provided with a shoulder which it engages in a cylindrical air gap. The cross section of the approach or the gap or both parts are designed according to the invention in such a way; that the free gap cross-section at each point of the gap changes when the approach join. Axial displacement of the armature to the magnet to the gap adjusted.

Elektromagnete mit quer zu den Kraftlinien verstellbarem Anker sind bekannt, aber nicht Elektromagnete mit einem veränderlichen, freien Spaltquerschnitt. Die Zugkraft des Magneten steht im umgekehrten Verhältnis zur Spaltbreite, so daß es möglich ist, durch die Querschnittsveränderung die Zugkraft nach einem bestimmten Gesetz in Abhängigkeit von der Stellung des Ankers zum Magneten zu regeln. Der Elektromagnet nach der Erfindung eignet sich zur Verwendung bei elektromechanischen Bremsen. Auf diesem Gebiet ist es besonders wichtig, den Kraftbedarf des Elektromagneten zu verringern und eine ständige und dabei sanfte Wirkung zu erzielen. Beides wird durch den veränderlichen Querschnitt erreicht.Electromagnets with an armature that can be adjusted transversely to the lines of force known, but not electromagnets with a variable, free gap cross-section. The pulling force of the magnet is inversely related to the gap width, so that it is possible, by changing the cross-section, the tensile force after a certain Law to regulate depending on the position of the armature to the magnet. The electromagnet according to the invention is suitable for use in electromechanical brakes. on In this area it is particularly important to reduce the force required by the electromagnet and to achieve a constant and gentle effect. Both become through the changeable Cross-section achieved.

Auf der Zeichnung ist als Ausführungsbeispiel ein Elektromagnet für eine elektromechanische Bremse im Schnitt durch die Achse dargestellt. Der Elektromagnet i hat die Form eines Hohlzylinders mit einem ebenfalls hohlzylindrischen Anker 2, der mit einer Zugstange 3 und einem Führungsstift 33 in einer Bohrung des Magneten i versehen ist. Der Anker trägt an beliebiger Stelle, hier in der Nähe seines Innenendes, eine Verdickung 32, mit der er in einen Spalt 35 des Magneten i eingreift. Der Spalt ist hier als ein zylindrischer Raum dargestellt. Es ist ersichtlich, daß bei der Bewegung des Ankers 2 der freie Spaltquerschnitt sich ständig ändert. Anstatt des Ankers kann auch der Spalt oder es können Spalt und Anker dem Ansatz 32 entsprechende Teile haben, .durch die die Querschnittänderung noch weiter beeinflußt wird. An den Spalt 35 schließt sich ein Hohlraum zur Aufnahme der Magnetspule 31 an.In the drawing is an electromagnet for an exemplary embodiment an electromechanical brake shown in section through the axis. The electromagnet i has the shape of a hollow cylinder with a likewise hollow-cylindrical armature 2, the one with a pull rod 3 and a guide pin 33 in a bore of the magnet i is provided. The anchor carries at any point, here near its inner end, a thickening 32 with which it engages in a gap 35 of the magnet i. The gap is shown here as a cylindrical space. It can be seen that in the Movement of the armature 2, the free gap cross-section is constantly changing. Instead of the The anchor can also be the gap or the gap and anchor can correspond to the shoulder 32 Have parts by which the change in cross-section is further influenced. At the gap 35 is followed by a cavity for receiving the magnetic coil 31.
