Description

Elektromagnetisch entgegen Federkraft ausrückbare Scheibenreibungsbremse bzw. -Kupplung Die Erfindung bezieht sich auf eine elektromagnetisch entgegen Federkraft ein- oder ausrückbare Seheibenreibungsbremse oder -kupplung, bei welcher der Luftspalt zwischen Ankerscheibe und Magnetkörper infolge Reibbelagabnutzung mittels einer als Schraubring ausgebildeten Druckscheibe nachstellbar ist, welche das Widerlager der Reibscheiben bildet.Disc friction brake that can be disengaged electromagnetically against spring force or clutch The invention relates to an electromagnetic counter-spring force engaging or disengaging disc friction brake or clutch, in which the air gap between armature disk and magnet body due to friction lining wear by means of a designed as a screw ring thrust washer is adjustable, which the abutment the friction disks forms.

Da bei einer im Betrieb befindlichen Bremse bzw. Kupplung der Luftspalt sich durch den Verschleiß des Reibscheibenpakets ständig vergrößert, muß er laufend kontrolliert werden, um ein überschreiten des zulässigen Grenzwerts des Luftspalts zu vermeiden. Die Kontrolle und Nachstellung des Luftspalts erfolgte bisher mittels Lehren, deren Abmessungen auf den Bedienungsanleitungen angegeben waren. Die Erfahrung hat jedoch gelehrt, daß eine solche Wartung betriebsmäßig nicht einwandfrei durchzuführen war, zumal die erforderliche Bedienungsanleitung nicht immer zur Hand ist.As the air gap when a brake or clutch is in operation is constantly increasing due to the wear of the friction disk set, it must continuously be checked to ensure that the permissible limit value of the air gap is exceeded to avoid. The control and readjustment of the air gap was previously carried out by means of Gauges the dimensions of which were given on the instruction manuals. The experience has taught, however, that such maintenance cannot be carried out properly from an operational perspective especially since the required operating instructions are not always at hand.

Nach der Erfindung wird die genaue Einstellung des Luftspalts dadurch vereinfacht und erleichtert, daß der Stellschlüssel für die Druckscheibe zugleich als deren Einstellehre dient, wobei diese in Nuten der Druckscheibe einzustecken ist, aus denen sie um das Maß des Luftspalts vorsteht und so zugleich die Maßlehre für den Luftspalt bildet.According to the invention, the precise setting of the air gap is thereby Simplified and facilitated that the key for the thrust washer at the same time serves as their setting gauge, these being inserted into grooves in the thrust washer from which it protrudes by the amount of the air gap and so at the same time the gauge forms for the air gap.

Auf der Zeichnung ist die neue Scheibenreibungsbremse in einem Ausführungsbeispiel in A b b. 1 im Schnitt dargestellt.In the drawing, the new disc friction brake is in one embodiment in A b b. 1 shown in section.

Die Ab b. 2 und 3 zeigen die Vorderseite der Druckscheibe, mit der sie am Reibscheibenpaket anliegt, und den Nachstellstift.The Ab b. 2 and 3 show the front of the thrust washer, with which it rests on the friction disk set, and the adjusting pin.

Der die Spule 2 enthaltende Magnetkörper 1 trägt die Stehbolzen 3, welche den Widerlagerring 6 für das aus den Innenlamellen 10 und den Außenlamellen 5 und 5a bestehende Reibscheibenpaket halten. Auf den Stehbolzen 3 sind die Außenlamellen 5, 5a und der Anker 4 des Elektromagneten verschiebbar geführt. Der Anker 4 wird im stromlosen Zustand der Bremse durch die Federn 9 des Magnetkörpers gegen das Reibscheibenpaket gedrückt und preßt dieses gegen die nachstellbare Druckscheibe 7. Zur Einstellung des Luftspalts S zwischen der Zugfläche des Elektromagneten und dem Anker ist in den Widerlagerring 6 die ringförinige Gegendruckscheibe 7 eingesehraubt, gegen welche sich das Reibscheibenpaket anlegt. Die Druckscheibe 7 wird durch die Feststellschraube 8 gesichert. Bei stromloser Spule drücken die Federn 9 mittels der Ankerscheibe 4 das Reibscheibenpaket zusammen und verbinden den Magnetkörper 1 kraftschlüssig mit dem Mitnehmer 11, wobei die Außenlamelle 5a die übertragung eines Reibmoments auf die Druckscheibe 7 verhindert. The magnet body 1 containing the coil 2 carries the stud bolts 3, which hold the abutment ring 6 for the friction disk set consisting of the inner disks 10 and the outer disks 5 and 5a. The outer lamellae 5, 5a and the armature 4 of the electromagnet are slidably guided on the stud bolts 3. When the brake is de-energized, the armature 4 is pressed against the friction disk set by the springs 9 of the magnet body and presses it against the adjustable pressure disk 7. To set the air gap S between the tensile surface of the electromagnet and the armature, the annular counter-pressure disk 7 is in the abutment ring 6 einehraubt, against which the friction disk pack rests. The thrust washer 7 is secured by the locking screw 8. When the coil is de-energized, the springs 9 compress the friction disk package by means of the armature disk 4 and connect the magnet body 1 to the driver 11 in a force-locking manner, the outer disk 5a preventing the transmission of a frictional torque to the pressure disk 7 .

Durch wachsenden Verschleiß vergrößert sich im stromlosen Zustand der Bremse bzw. Kupplung der Luftspalt S zwischen Elektromagnet und Anker. Eine Rückführung des Luftspalts auf seinen Ausgangswert geschieht durch die Verdrehung der Druckscheibe 7 nach vorherigem Lösen der Sicherungsschraube 8. As the wear and tear increases, the air gap S between the electromagnet and the armature increases when the brake or clutch is de-energized. The air gap is returned to its initial value by rotating the thrust washer 7 after the locking screw 8 has been loosened.

Zu ihrer Einstellung hat die ringförmige Gegendruckscheibe 7 an ihrer dem Reibscheibenpaket zugekehrten Planseite radiale Nuten 12 von der Tiefe t und der Breite b (A b b. 2), in welche ein prismatischer Einstellstab 13 von der Breite b und der Höhe ti eingeführt wird, mit dem die Druckscheibe 7 zu drehen ist. Der Einstellstab steht auf der Planseite der Druckscheibe um den Differenzbetrag t, - t, der gleich ist dem günstigstem Luftspalt S, vor. Durch Rechtsdrehung, von der Druckscheibenseite der Bremse her gesehen, wird die Druckscheibe so lange gedreht, bis Widerstand spürbar wird. Nach Entfernung des Einstellstabs 13 ist die Bremse bzw. Kupplung auf den günstigsten Wert des Luftspaltes S = t, - t ohne Messung eingestellt.To adjust it, the annular counter-pressure disk 7 has, on its flat side facing the friction disk set, radial grooves 12 of depth t and width b (A b b. 2), into which a prismatic setting rod 13 of width b and height ti is inserted. with which the thrust washer 7 is to be rotated. The adjustment rod protrudes on the flat side of the thrust washer by the difference t, - t, which is equal to the most favorable air gap S. By turning to the right, viewed from the pressure disc side of the brake, the pressure disc is rotated until resistance is felt. After removing the setting rod 13 , the brake or clutch is set to the most favorable value of the air gap S = t, - t without measurement.

Der Nachstellstift 13 hat somit eine doppelte Wirkung, er ist Verstellwerkzeug und Meßwerkzeug für den Luftspalt S. The adjusting pin 13 thus has a double effect, it is an adjusting tool and a measuring tool for the air gap S.
