Description
Stromzuführung für mindestens zwei auf verschiedenen Wellen gelagerte elektromagnetisch betätigte Reibungskupplungen Es ist bekannt, daß in Wälzlagern, die von elektrischem Strom durchflossen werden, Riffelbildung auf den Laufflächen auftreten kann. Vorzugsweise handelt es sich hierbei um Lager von elektromotorisch betriebenen Fahrzeugen. Aber auch in Schaltgetrieben mit elektromagnetisch betätigten Reibungskupplungen treten bei Stromdurchgang Beschädigungen der Wellenlager auf.Power supply for at least two supported on different shafts electromagnetically operated friction clutches It is known that in rolling bearings, which are traversed by electric current, corrugation on the running surfaces can occur. These are preferably electromotive bearings operated vehicles. But also in manual transmissions with electromagnetically operated Friction clutches cause damage to the shaft bearings when a current passes through them.
Als Abhilfe wurde bereits vorgeschlagen, die Lager durch dünne Schichten aus nichtleitendem Material vom Gehäuse zu isolieren. Die Maßhaltigkeit solcher Schichten ist jedoch nicht ausreichend:. Es ist auch bekannt, zur Entlastung solcher Lager eine Strombrücke vorzusehen. Hierbei ist jedoch Voraussetzung, daß der Übergangswiderstand der Brückenkontakte klein ist gegenüber dem im Wälzlager. Durch schwankende Übergangswiderstände in der vorhandenen Stromverzweigung werden hierdurch aber Lagerschäden nicht mit Sicherheit vermieden, insbesondere wenn das Gehäuse als gemeinsame Rückleitung für mehrere Stromquellen bzw. Verbraucher dient.As a remedy, it has already been suggested to apply thin layers to the bearings to be insulated from non-conductive material from the housing. The dimensional accuracy of such However, layers is not sufficient: It is also known to help relieve such Stock to provide a current bridge. However, it is a prerequisite that the contact resistance the bridge contacts are small compared to that in the roller bearing. Due to fluctuating contact resistances However, this does not cause bearing damage in the existing power junction Avoided safety, especially when the case is used as a common return line for several power sources or consumers are used.
Nach der Erfindung wird vorgeschlagen, für eine oder mehrere auf einer Welle gelagerte elektromagnetisch betätigte Reibungskupplungen, insbesondere Schaltkupplungen für Wechselgetriebe eine gemeinsame direkte Rückleitung, und zwar entweder eine auf dem einen Kupplungskörper oder eine auf der Welle schleifende Kontaktbürste vorzusehen. Dabei ist Voraussetzung, daß alle direkt leibend miteinander verbundenen Kupplungen eine gemeinsame von der Stromquelle einer anderen Welle galvanisch getrennte Stromquelle besitzen. Durch diese Stromführung sind die Lager nicht mehr stromdurchflossen, und es können auch keine Ausgleichsströme zwischen den Wellen über das Gehäuse und die Zahnräder fließen. Die vorgeschlagene Stromableitung hat .auch den Vorteil, daß sie nachträglich in eingebauten Getrieben angebracht werden kann. Vorzugsweise wird auf dem zur Rückleitung dienenden Kupplungskörper eine oberflächengehärtete Zone geschaffen, auf der die Rückleitungsbürste schleift.According to the invention it is proposed for one or more on one Electromagnetically operated friction clutches mounted on shafts, in particular clutches for change gears a common direct return line, either one on one coupling body or a contact brush sliding on the shaft to be provided. It is a prerequisite that all are directly connected with each other Couplings have a common galvanically isolated from the power source of another shaft Own power source. This current conduction means that the bearings no longer have current flowing through them, and there can also be no equalizing currents between the shafts via the housing and the gears flow. The proposed current discharge also has the advantage of that it can be retrofitted in built-in gearboxes. Preferably a surface-hardened one is applied to the coupling body used for the return line Zone created on which the return brush rubs.
Die Zeichnung stellt das Schaltschema eines Ausführungsbeispiels der Erfindung dar.The drawing represents the circuit diagram of an embodiment of the Invention.
Es sind 1 und 2 zwei voneinander getrennte Wellen eines Schaltgetriebes. Auf der Welle 1 sind zwei elektromagnetisch betätigte Reibungskupplungen 3 und 4 gelagert, welche durch je eine Magnetspule 5 und 6 betätigt werden. Auf der Welle 2 ist eine Magnetkupplung 7 gelagert, welche durch eine Magnetspule 8 betätigt wird.1 and 2 are two separate shafts of a manual transmission. On the shaft 1 there are two electromagnetically operated friction clutches 3 and 4 stored, which are actuated by a solenoid 5 and 6 each. On the wave 2, a magnetic coupling 7 is mounted, which is actuated by a magnetic coil 8.
Daseine Ende der Magnetspule 5 ist mit einem isolierten Schleifring 9 und das andere Ende mit dem Mitnehmerring 10 der Kupplung 3 leitend verbunden. Entsprechend wind die Enden der Magnetspule 6 mit dem Schleifring 11 und mit dem Mitnehmerring 12 der Kupplung 4 leitend verbunden.One end of the solenoid 5 is provided with an insulated slip ring 9 and the other end is conductively connected to the driver ring 10 of the coupling 3. Accordingly, the ends of the solenoid 6 wind with the slip ring 11 and with the Driving ring 12 of the clutch 4 is conductively connected.
Die Magnetspule 8 der Kupplung 7 ist einerseits mit dem Schleifring 13 und andererseits mit dem Mitnehmerring 14 verbunden.The magnetic coil 8 of the clutch 7 is on the one hand with the slip ring 13 and, on the other hand, connected to the driver ring 14.
Als Stromquelle dient ein Transformator mit der Primärwicklung 20 und en beiden Sekundärwicklungen 21 und 22. Die beiden Sekundärwicklungen speisen zwei Gleichrichter 23 und 24. Die Plusklemme des Gleichrichters 23 ist über Schalter 25 und 26 durch Schleifbürsten mit den Schleifringen 9 und 11 verbunden. Die Rückleitung ist gemeinsam für beide Magnetspulen 5 und 6 und besteht aus einer Bürste 27, welche auf einer oberflächengehärteten Zone des Mi:tnehmerrings 12 schleift und mit der Minusklemme des Gleichrichters 23 verbunden ist.A transformer with the primary winding 20 is used as the current source and en both secondary windings 21 and 22. Feed the two secondary windings two rectifiers 23 and 24. The positive terminal of the rectifier 23 is via switches 25 and 26 connected to the slip rings 9 and 11 by grinding brushes. The return line is common to both solenoids 5 and 6 and consists of a brush 27, which grinds on a surface-hardened zone of the driver ring 12 and with the Minus terminal of the rectifier 23 is connected.
Die Kupplung 7 wird aus dem Gleichrichter 24 getrennt mit Strom versorgt. Die Plusklemme ist über den Schalter 28 und die Bürste 29 mit dem Schleifring 13 verbunden. Die Rückleitung besteht aus einer Bürste 30, die auf einer oberflächengehärteten Zone des Mitnehmerrings 14 schleift und mit der Minusklemme des Gleichrichters 24 verbunden ist.The coupling 7 is supplied with power separately from the rectifier 24. The positive terminal is connected to the slip ring 13 via the switch 28 and the brush 29 tied together. The return line consists of a brush 30 which is hardened on a surface Zone of the driver ring 14 grinds and with the negative terminal of the rectifier 24 connected is.
Statt durch die Mitnehmerringe 12 und 14 kann der Strom von den Magnetspulen auch durch Bürsten 31 zurückgeführt werden, die unmittelbar auf den Wellen 1 und 2 schleifen.Instead of passing through the driver rings 12 and 14, the current can flow from the solenoid coils can also be returned by brushes 31, which are directly on the shafts 1 and 2 loops.
