Description

Es ist bereits ein,. Hauptstromwiderstandsregler vorgeschlagen, der sowohl für die Reihen- als auch für Parallelschaltung der Triebmotoren elektrischer Fahrzeuge verwendet wird. Dieser Hauptstromwiderstandsregler besteht aus zwei voneinander getrennten, durch eine besondere Schalteinrichtung verbindbaren Widerstandsteilen mit gestreckter Kontaktbahn, die derart angeordnet sind, daß sie von zwei sich gegenläufig bewegenden Schleifstücken jeweils der Reihe nach bestrichen werden können.It's already a. Main current resistance regulator proposed the for both series and parallel connection of the electric traction motors Vehicles is used. This main flow resistance regulator consists of two of each other separate resistance parts that can be connected by a special switching device with elongated contact track, which are arranged in such a way that they run in opposite directions of two moving grinding pieces can be coated one after the other.

Die Erfindung betrifft gleichfalls eine feinstufige Steuerung für Gleichstromfahrzeuge mit zwei miteinander in Reihe oder zueinander parallel geschalteten Fahrmotoren oder Fahrmotorgruppen und nach Art eines Schiebewiderstandes ausgebildeten Regelwiderständen, bei denen die Widerstandskontaktbahn in zwei hintereinander angeordnete, durch ein Isolierstück voneinander getrennte Hälften unterteilt ist und die Kontaktbürsten in gegenläufigem, jedoch für die Reihen-und Parallelschaltstellungen gleichbleibendem Sinn über die Kontaktbahn bewegt werden. In Fig. i bis 3 der Zeichnung .ist schematisch die Schaltung einer solchen Steuerung im Verlauf eines Anfahrvorganges dargestellt. i und a sind die Anker der beiden Fahrmotoren, 3 und 4 die zugehörigen Erregerwicklungen, 5 und 6 zwei Kontaktbahnen, mit denen nicht dargestellte Widerstände in' Verbindung stehen. Die beiden Kontaktbahnen 5 und 6 sind durch das Isolierstück 1a voneinander getrennt. Die Verbindung der Kontaktbahnen mit den Fahrmotoren erfolgt über die Kontaktbürsten 7 und B. Die Schalter 9, io und, i i dienen zur Herstellung der gewünschten Fahrmotorgrupp.ierung. Die Schalter sind zweckmäßig als Nockenschalter ausgebildet, die von einer mit der - Antriebsvorrichtung für die Kontaktbürsten 7 und 8 gekuppelten, nicht dargestellten Nockenwalze gesteuert werden. Jedoch kann auch jede andere Schalterart Verwendung finden.The invention also relates to a fine-level control for DC vehicles with two connected in series or parallel to each other Traction motors or groups of traction motors and designed in the manner of a sliding resistor Variable resistors, in which the resistance contact path in two consecutively arranged, is divided by an insulating piece separated from each other halves and the contact brushes in opposite directions, but the same for the series and parallel switching positions Sense to be moved over the contact path. In Fig. I to 3 of the drawing .ist is schematic the circuit of such a control shown in the course of a start-up process. i and a are the armatures of the two traction motors, 3 and 4 the associated excitation windings, 5 and 6 two contact tracks with which resistors (not shown) are connected stand. The two contact tracks 5 and 6 are separated from one another by the insulating piece 1a separated. The contact tracks are connected to the traction motors via the Contact brushes 7 and B. The switches 9, io and, i i are used to produce the desired Drive motor grouping. The switches are expediently designed as cam switches, the one coupled with the - drive device for the contact brushes 7 and 8, cam roller, not shown, can be controlled. However, any other type of switch can also be used Find use.

In der in Fig. i dargestellten Reihenschaltung der Fahrmotoren ist der Schalter io geschlossen, während die Schalter 9 und ii offen sind. Die Fahrmotoren sowie die Kontaktbahnen 5 und 6 sind miteinander in Reihe geschaltet. Die Kontaktbürsten 7 und 8 werden gegenläufig in Pfeilrichtung, also im Sinne .abnehmenden Widerstandes, bewegt. Sobald dies vollständig geschehen ist, .liegen die beiden Fahrmotoren in Reihenschaltung an der Netzspannung. Bevor jedoch die Parallelschaltung der Fahrmotoren hergestellt wird, werden die Kontaktbürsten 7 und 8 weiterbewegt, bis die Kontaktbürste 7 auf der Kontaktbahn 6 und die Kontaktbürste 8 auf der Kontaktbahn 5 aufliegt, wie Fig. a zeigt. Nun werden die Schalter 9 und i i geschlossen, und der Schalter io wird geöffnet. Diese Schaltstellung zeigt Fig. 3. Die Parallelschaltung der Fahrmotoren ist damit hergestellt. Dem Fahrmotor i bis 3 ist jetzt die Kontaktbahn 6 und dem Fahrmotor a bis 4 die Kontaktbahn 5 vorgeschaltet. Die Kontaktbürsten 7 und 8 werden im gleichen Sinne wie auf den Reihenschaltstellungen weiterbewegt, bis die Widerstände ausgeschaltet sind und beide Fahrmotoren zueinander parallel an der vollen Netzspannung liegen.In the series connection of the traction motors shown in FIG switch io is closed while switches 9 and ii are open. The traction motors and the contact tracks 5 and 6 are connected in series with one another. The contact brushes 7 and 8 are opposite in the direction of the arrow, i.e. in the sense of decreasing resistance, emotional. As soon as this is completely done, the two traction motors are in Series connection to the mains voltage. But before the parallel connection of the traction motors is established, the contact brushes 7 and 8 are moved on until the contact brush 7 rests on the contact track 6 and the contact brush 8 rests on the contact track 5, as Fig. a shows. Now the switches 9 and i i are closed, and the switch io opens. This switching position is shown in FIG. 3. The parallel connection of the traction motors is made with it. The traction motor i to 3 is now the contact track 6 and the Drive motor a to 4, the contact track 5 upstream. The contact brushes 7 and 8 are moved on in the same sense as on the series switching positions until the resistances are switched off and both traction motors are connected to full mains voltage in parallel lie.

Die Erfindung betrifft eine Weiterbildung dieser Steuerung und ist dadurch gekennzeichnet, daß durch Verbindung des Anfangs je einer Kontaktbahnhälfte mit dem Verbindungspunkt zwischen Anker und Feldwicklung eine Anfahrt mit geschwächtem Feld erzielt wird. Diese Ausführungsform hat den Vorteil, daß man mit weniger Widerständen auskommt als wenn man durch die Vorschaltwiderstände allein eine sanfte Anfahrt erreichen wollte. Eine solche Anfahrt mit Feldschwächung läßt sich erfindungsgemäß zwanglos mit der eingangs erwähnten Steuerung ausführen.The invention relates to a development of this control and is characterized in that one contact track half is connected by connecting the beginning with the connection point between armature and field winding an approach with weakened Field is achieved. This embodiment has the advantage that there are fewer resistors as if the series resistors alone give you a gentle approach wanted to achieve. Such an approach with field weakening can be achieved according to the invention run casually with the control mentioned at the beginning.

Hierzu wird, wie in Fig. 4 für eine Schaltwerkshälfte angedeutet ist, die Feldwicklung 3 durch einen Schalter 13 mit dem Anfang des Widerstandes verbunden. Steht die Kontaktbürste* 7 ganz links, so ist die Feldwicklung 3 kurzgeschlossen. Da dann nur im Anker i Strom fließt, kommt kein Drehmoment zustande. In dem Maße, in dem die Kontaktbürste 7 nach rechts bewegt wird, nimmt der Feldstrom zu, so daß sich das Drehmoment ganz allmählich steigert. Auf diese Weise ergibt sich ein sehr sanftes Anfahren. Hat der Feldstrom seinen vollen oder nahezu vollen Wert erreicht, so kann der Schalter 13 funkenfrei geöffnet werden.For this purpose, as indicated in Fig. 4 for one half of the rear derailleur, the field winding 3 is connected through a switch 13 to the beginning of the resistor. If the contact brush * 7 is on the far left, the field winding 3 is short-circuited. Since current then only flows in armature i, no torque is produced. In this scale, in which the contact brush 7 is moved to the right, the field current increases, so that the torque increases very gradually. In this way it results in a great deal gentle start. If the field current has reached its full or almost full value, so the switch 13 can be opened without sparking.
