Description

Steuereinrichtung, insbesondere für elektrisch betriebene Fahrzeuge Im Patent 617 826 ist eine Steuereinrichtung angegeben, die insbesondere für elektrische Fahrzeuge bestimmt ist und bei der bei Bewegung des Schaltwerkes über die Reihenschaltstellungen eine Feder ,aufgeladen wird, die das Schaltwerk während der Parallelschaltung zurückbewegt.Control device, in particular for electrically operated vehicles Patent 617 826 specifies a control device which is intended in particular for electric vehicles and in which a spring is charged when the switching mechanism is moved through the series switching positions, which moves the switching mechanism back during the parallel connection.

Die Erfindung, die .eine weitere Verbesserung der Anordnung nach dem Hauptpatent betrifft, besteht darin, daß der Schleifkontakt eines#Kollektorreglers oder geradlinigen Kontaktbahm-eglers, mit dem die Anlaßwiderstände geschaltet -werden, aus zwei in der Schaltrichtung gegeneinander verlagerten, starr miteinander verbundenen' Bürstan besteht oder so breit benessen ist, daß er nach dem Durchschalten der Kontaktbahn in einer Richtung und bei dem dann erfolgenden überging in die Parallelschaltung einem Teil des Widerstandes kurzgeschlossen hält, in seiner Anfangslage, d. h. vor -Beginn des Schaltens, jedoch so weit von der Kontaktbahn abgelaufen ist, daß der gesamte Widerstand in den Stromkreis eingeschaltet ist. Durch diese Anordnung werden besondere Umschalteinrichtungen für den Widerstand bzw. Zusatzwiderstände ;erspart. Bei bereits vorhandegnen Schleifkontakten, die über Kontaktbahnen gleiten, ist es bekannt, zwei miteinander gekuppelte Bürsten zu verwenden. Diese sind jedoch gegeneinander nicht versetzt und haben lediglich den Zweck, den Strom von den Kontakten der Regelvorrichtung auf eine parallel danebenliegende Kontaktschiene zu übertragen.The invention. A further improvement of the arrangement according to the The main patent relates to the fact that the sliding contact of a # collector regulator or straight contact bahm regulator with which the starting resistors are switched, consisting of two rigidly connected to each other in the switching direction Bürstan exists or is so broad that it is after switching through the contact path in one direction and in the one that then took place, it was switched to parallel connection keeps part of the resistor short-circuited, in its initial position, d. H. before -Beginning of switching, but has expired so far from the contact track that the all resistance in the circuit is turned on. This arrangement will be special switching devices for the resistor or additional resistors; saved. In the case of existing sliding contacts that have contact tracks slide, it is known to use two brushes coupled together. However, these are are not offset against each other and only have the purpose of removing the current from the contacts to transfer the control device to a parallel adjacent contact rail.

In der Zeichnung ist ein Ausführungsbeispiel dargestellt. Abb. i zeigt die Motorschaltung in der Reihenschaltstellung der Fahrmotoren und Abb. 2 bei Beginn der Parallelschaltung. Gemäß Abb. i liegen die Motoranker 2o und 21 bzw. 22 und 23 mit ihren Feldwicklungen 2q. und 25 bzw. 26 und 27 in Reihe mit den Widerstandssätzen 28 und 29 zwischen der Fahrleitung und Erde. Jedem Widerstand 28 und 29 sind im vorliegenden Fall zwei starr miteinander verbundene Kontakte 3o und 31 zugeordnet, 'die bei der Bewegung in der angegebenen Pfeilrichtung auf den den Widerständen 28 und 29 zugeordneten Kontaktbahnen schleifen. Bei der in Abb. i gezeichneten Anfangslage liegen indessen nur die Schleifbürsten 31 auf jeweils dem ersten Kontakt der Schleifbahnen auf, so daß der ganze Widerstand in den Stromkreis eingeschaltet ist. Während der Reihenschaltung werden beide Bürstensätze 30, 31 in der gleichen Schaltrichtung bewegt. Beim Kurzschließen der Widerstände in der angegebenen Richtung gelangt :nach einiger Zeit der zweite Kontakt 30 auf die Kontaktbahn der Widerstände 28 bzw. 29, löst jedoch keine besonderen Wirkungen aus, da er auf bereits kurzgeschlossenen Kontakten aufliegt. Haben die Gleitbürsten die in Abb. 2 gezeichnete Lage erreicht, so sind bei der Reihenschaltung der Motoren gleichwohl die ganzen Widerstände kurzgeschlossen. Wird dann auf die ,in Abb. 2 dargestellte Parallelschaltung übergegangen, so ist durch den zweiten Kontakt einer jeden Bürste ein Teil des Widerstandes 28 bzw. 29 selbsttätig kurzgeschlossen, und der Widerstand hat dadurch jenen Wert, den er beim LTbergang auf die Parallelschaltung aufweisen muß. Das Durchschalten in der anderen Schaltrichtung (Abb. 2) bewirkt dann das Kurzschließen der im Ohmwert verringerten Widerstände.An exemplary embodiment is shown in the drawing. Fig. I shows the motor connection in the series connection position of the traction motors and Fig. 2 at the beginning of the parallel connection. According to Fig. I, the motor armatures 2o and 21 or 22 and 23 are located with their field windings 2q. and 25 and 26 and 27 in series with the resistance sets 28 and 29 between the contact line and earth. In the present case, each resistor 28 and 29 is assigned two rigidly interconnected contacts 3o and 31, which slide on the contact paths assigned to the resistors 28 and 29 when moving in the indicated arrow direction. In the initial position shown in Fig. I, however, only the brushes 31 rest on the first contact of the sliding tracks, so that the entire resistance is switched on in the circuit. During the series connection, both sets of brushes 30, 31 are moved in the same switching direction. When the resistors are short-circuited in the specified direction: after some time, the second contact 30 hits the contact path of the resistors 28 or 29, but does not trigger any special effects because it rests on contacts that have already been short-circuited. If the sliding brushes have reached the position shown in Fig. 2, all the resistors are short-circuited when the motors are connected in series. If you then switch to the parallel connection shown in Fig. 2, part of the resistor 28 or 29 is automatically short-circuited by the second contact of each brush, and the resistance thus has the value that it must have at the transition to the parallel connection . Switching through in the other switching direction (Fig. 2) then short-circuits the resistances with a reduced ohmic value.
