Description

Schleifkontakt-Stromzuführung bei Elektromagnet-Getriebeschaltkupplungen mit umlaufendem Schleifring Die Erfindung befaßt sich mit der Schleifkontakt-Stromzuführung bei Elektromagnet-Getriebeschaltkupplungen mit umlaufendem Schleifring, wobei mindestens zwei in Umfangsrichtung des Schleifringes hintereinander angreifende Stromzuführungsbürsten vorgesehen sind.Sliding contact power supply for electromagnetic gear shift clutches with rotating slip ring The invention is concerned with the sliding contact power supply in the case of electromagnetic gear shift clutches with a rotating slip ring, with at least two power supply brushes attacking one behind the other in the circumferential direction of the slip ring are provided.

Es ist bei Kommutatormaschinen bereits bekanntgeworden, zwei auf der Kommutatorumfangsfläche in geringem Abstand hintereinandergereihte Bürsten zueinander etwas v ersetzt anzuordnen. .Damit soll die sonst bei axial unversetzt angeordneten Bürstenpaaren auftretende, durch die unvermeidlichen Zwischenräume zwischen Bürsten des gleichen Bolzens bedingte Gratbildung vermieden werden. Dort aber, wo die axial äußeren Endkanten der Bürsten auf die Kommutatorumfläche auftreffen, bilden sich jedoch trotzdem Grate, die unter Umständen den Stromübergang stören können, zu deren Verhinderung bisher nichts unternommen wurde.It has already become known in commutator machines, two on the Brushes lined up one behind the other at a short distance from one another to arrange something v replaced. .This means that the otherwise axially not offset Brush pairs occurring due to the inevitable gaps between brushes the formation of burrs caused by the same bolt can be avoided. But where the axial the outer end edges of the brushes hit the commutator surface, are formed however, burrs that can interfere with the current transfer under certain circumstances, to their Prevention so far nothing has been done.

Gegenüber dieser bekannten Bürstenanordnung handelt es sich beim Erfindungsgegenstand um die Verwendung von Bürsten, die mittels des im Innern eines Geschwindigkeitswechselgetriebes herumspritzenden Öles und sich bildenden Öldunstes geschmiert werden. Bei ungenügender Verdrängung des auf der Schleifringoberfläche vorhandenen Ölfilmes entstehen Funken, die Einbrennungen in der Schleifringoberfläche zur Folge haben. Diese Unebenheiten geben Anlaß zu häufigen Stromunterbrechungen. Zur Vermeidung solcher Störungen ist erfindungsgemäß die Möglichkeit gegeben, die zu jedem Schleifring gehörigen Bürsten im wesentlichen in Richtung der Drehachse des Schleifringes zu verstellen, um sie auf unbeschädigte Zonen der Ringoberfläche zu bringen. In den jeweils eingestellten Lagen sind die Bürsten feststellbar.Compared to this known brush arrangement, it is the subject of the invention to the use of brushes, which by means of the inside of a speed change gear splashing oil and oil vapor that forms are lubricated. If it is insufficient Displacement of the oil film on the slip ring surface creates sparks, which result in burns in the slip ring surface. These bumps give rise to frequent power interruptions. To avoid such disturbances is according to the invention given the possibility of the brushes belonging to each slip ring to be adjusted essentially in the direction of the axis of rotation of the slip ring to it to bring to undamaged zones of the ring surface. In the respectively set The brushes can be determined in different positions.

Die Zeichnung läßt ein Ausführungsbeispiel der Erfindung erkennen.The drawing shows an embodiment of the invention.

Abb.1 ist eine Seitenansicht eines Schleifringes mit zwei Stromzuführungsbürsten; Abb. 2 zeigt den Schleifring im Längsschnitt; Abb. 3 zeigt einen Teil des Schleifringes, von oben gesehen, und dazu einen verstellbaren Halter für eine Stromzuführungsbürste.Figure 1 is a side view of a slip ring with two power supply brushes; Fig. 2 shows the slip ring in longitudinal section; Fig. 3 shows part of the slip ring, seen from above, and an adjustable holder for a power supply brush.

In Abb.1 und 2 sind zwei Stromzuführungsbürsten 1 und 2 unter einem beliebigen Winkel auf den Schleifringumfang verteilt angeordnet, jedoch in der Achsrichtung des Schleifringes 3 zueinander versetzt, wie es Abb.2 erkennen läßt. Jede Schleifbürste 1 ist in einem hülsenförmigen Körper 4 gefaßt, und ihre Stromzufuhr erfolgt über die Leitungsanschlußstelle 5. Der Halter 6 ist, wie Abb. 3 zeigt, beispielsweise ein doppelarmiger Hebel, der um einen am Getriebegehäuse 7 angebrachten Bolzen 8 drehbar ist. Das eine Hebelende greift mit einem Längsschlitz über einen Stift 9, der in einer Schraube 10 festsitzt. Die Schraube 10 sitzt mit ihrem Gewinde in der Gehäusewand 7 und kann mit Hilfe der beiden Muttern 11, 12 in den jeweils eingestellten Lagen gesichert werden. Wie aus Abb. 3 ersichtlich, erlaubt die Verstellung des Traghebels 6 eine Verlagerung einer jeden Stromzuführungsbürste 1 über die Breite der Schleifringoberfläche hin. Hier beim Ausführungsbeispiel verläuft der Verstellweg der Bürste in einem Kreisbogen, der aber im wesentlichen einer Bewegung in Richtung der Drehachse des Schleifringes gleichkommt. Die Halterung könnte auch so ausgestaltet sein, daß eine Verstellbarkeit der Bürste genau in Richtung der Drehachse des Schleifringes möglich ist.In Fig.1 and 2 there are two power supply brushes 1 and 2 under one Any angle arranged distributed on the slip ring circumference, but in the axial direction of the slip ring 3 offset from one another, as can be seen in Fig.2. Any sanding brush 1 is held in a sleeve-shaped body 4, and its power is supplied via the line connection point 5. The holder 6 is, as Fig. 3 shows, for example a double-armed lever, which moves around a bolt 8 attached to the gear housing 7 is rotatable. One end of the lever engages with a longitudinal slot over a pin 9, which is stuck in a screw 10. The screw 10 sits with its thread in the Housing wall 7 and can with the help of the two nuts 11, 12 in the respectively set Layers are secured. As can be seen from Fig. 3, the adjustment of the Support lever 6 a displacement of each power supply brush 1 across the width the slip ring surface. Here in the exemplary embodiment, the adjustment path runs the brush in an arc of a circle, but which is essentially one movement in the direction of equals the axis of rotation of the slip ring. The holder could also be designed in this way be that an adjustability of the brush exactly in the direction of the axis of rotation of the slip ring is possible.

Wesentlich ist, daß man nach Abnutzung bzw. Beschädigung von Schleifringzonen die Bürsten an andere Stellen der Schleifringbreite bringen kann, wo noch keine Abnutzung erfolgt ist.It is essential that one after wear or damage to slip ring zones can move the brushes to other places in the width of the slip ring where none have yet Wear is done.
