Description
Kollektorregler für elektrisch betriebene Fahrzeuge zur feinstufigen Widerstandsregelung beim Fahren und Bremsen Die Erfindung bezieht sich auf einen Kollektorregler für elektrisch betriebene Fahrzeuge zur feinstufigen Widerstandsregelung beim Fahren und Bremsen. Mit Vorteil werden derartige als Kollektorregler ausgebildete Widerstandsregelgeräte verwendet, da sie bei kleinstem Raumbedarf und größter Wirtschaftlichkeit der Herstellung die erwünschte feinstufige Unterteilung der Widerstände in einfachster Weise ermöglichen.Collector controller for electrically powered vehicles for fine-grained Resistance control when driving and braking The invention relates to a Collector controller for electrically powered vehicles for fine-level resistance control when driving and braking. Such are advantageously designed as collector regulators Resistance regulators are used because they take up the smallest space and are extremely economical the desired finely graded subdivision of the resistors into the simplest Way enable.
Die Unterschiedlichkeit der Verhältnisse im Fahr- und Bremsbetrieb und die damit erforderlich werdende Abstufung der Widerstände hat ihren Grund darin, daß einerseits die beim Bremsen aus voller Fahrt auftretenden Bremsspannungen ein Mehrfaches der normalen Betriebsspannung betragen können und andererseits die Lamellenspannung mit Rücksicht auf die mechanische und elektrische Festigkeit der Kollektoren einen bestimmten Wert nicht überschreiten darf, wenn das bei höheren Lamellenspannungen auftretende Kontaktfeuer mit den damit einhergehenden Erscheinungen des Verschmorens mit Sicherheit vermieden werden soll.The difference in the conditions in driving and braking and the necessary gradation of the resistances is due to that on the one hand the braking voltages occurring when braking at full speed Can be a multiple of the normal operating voltage and, on the other hand, the lamella voltage with regard to the mechanical and electrical strength of the collectors must not exceed a certain value if this is the case with higher lamella tensions Occurring contact fire with the accompanying symptoms of charring to be avoided with certainty.
Die Erfindung setzt sich nun zur Aufgabe, bei derartigen Regelgeräten die denkbar beste Anpassung der Widerstände an die wirklichen Verhältnisse zu ermöglichen. Kollektorregler, bei denen die gleichen Lamellen für den Fahr-und Bremsbetrieb dienen, haben den Nachteil, daß die Widerstandsstufen unter sich alle gleich sein müssen und somit den praktischen Anforderungen des Betriebes, namentlich bei höheren Leistungen, nicht oder nur schwierig angepaßt werden können. Diese Schwierigkeiten werden erfindungsgemäß dadurch behoben, daß getrennte Lamellen für Fahren und Bremsen angeordnet werden. Für beide Betriebszustände können dabei entweder getrennte oder auch gemeinsame Widerstandssätze vorgesehen werden. Die Abstufung der Widerstände kann nunmehr nach Anzahl und Größe der Stufen verschieden vorgenommen und damit den praktischen Bedürfnissen des Fahr- und Bremsbetriebes vollkommen angepaßt werden. Durch eine solche Unterteilung ist es möglich, daß Anfahrbeschleunigung und Kurzschlußbremsung ohne Einbuße an Betriebssicherheit unmittelbar in der Nähe der Reibungsgrenze stattfinden, also bis auf den höchsten Beschleunigungs- und Bremswert gebracht werden können. Durch die unterschiedliche Abstufung der . Widerstände für das Fahren und Bremsen wird es gleichzeitig möglich, die mechanische und elektrische Festigkeit des Kollektors erheblich besser auszunutzen. Man hat es somit in der Hand, den zeitlichen Ablauf der Regelvorgänge beim Bremsen und Fahren so zu wählen, wie es für den Führer des Wagens am bequemsten ist. Unter bestimmten Umständen empfiehlt es sich darüber hinaus, den getrennten Fahr- und Bremslamellen auch noch getrennte Bürsten zuzuordnen. Diese Trennung der Bürsten hat den Vorteil, daß Anfahr- und Bremsvorgang sogleich bei Betätigung der Fahr- bzw. Bremswalze ohne weitere Verzögerung und ohne Rücksicht auf die jeweilige Stellung der anderen Bürste eingeleitet werden können. Ein Zurückführen von Bürsten in die Ausgangslage, bevor der nächste Anfahr- oder Bremsvorgang eingeleitet werden kann, ist nicht mehr erforderlich. Die Betriebssicherheit elektrisch betriebener Fahrzeuge wird hierdurch erheblich verbessert, können doch hiermit selbst bei den heute üblichen hohen Fahrgeschwindigkeiten kürzeste Anfahr- und Bremswege erzielt werden. Schließlich bietet die Trennung der Bürsten auch noch die Möglichkeit, daß im Störungsfall einer der beiden Bürsten ein völliges Ausfallen der Betriebsfähigkeit des Fahrzeuges vermieden wird.The invention now has the task of regulating devices of this type to enable the best possible adjustment of the resistances to the real conditions. Collector regulators in which the same slats are used for driving and braking, have the disadvantage that the resistance levels are among themselves all same must be and thus the practical requirements of the company, in particular higher performance, cannot be adapted or only with difficulty. These difficulties are solved according to the invention in that separate slats for driving and braking to be ordered. Either separate or common resistance sets can also be provided. The gradation of the resistances can now be made differently according to the number and size of the stages and thus be fully adapted to the practical needs of driving and braking. Such a subdivision makes it possible for starting acceleration and short-circuit braking take place in the immediate vicinity of the friction limit without any loss of operational safety, so can be brought up to the highest acceleration and braking value. Due to the different gradation of the. Resistances for driving and braking it becomes possible at the same time, the mechanical and electrical strength of the collector to be used considerably better. So you have it in your hand, the timing of the control processes when braking and driving to be selected as it is for the driver of the Is the most comfortable in the car. In certain circumstances it is also advisable to to assign separate brushes to the separate driving and brake lamellas. These Separation of the brushes has the advantage that the starting and braking process occur at the same time Actuation of the driving or braking roller without further delay and without consideration can be initiated on the respective position of the other brush. A return from brushes to the starting position before the next start-up or braking process is initiated is no longer required. The operational safety of electrically operated Vehicles will be significantly improved as a result, but can even be used with the The high travel speeds that are common today achieve the shortest possible approach and braking distances will. Finally, the separation of the brushes also offers the possibility that in the event of a fault in one of the two brushes, there is a complete failure of its operability of the vehicle is avoided.
Die Zeichnung zeigt ein Ausführungsbeispiel des Erfindungsgedankens.The drawing shows an embodiment of the inventive concept.
Der Kollektor IL ist als Innenkollektor ausgebildet. Die einzelnen Lamellen sind mit L bezeichnet. Zwischen den Fahr- und Bremslamellen sind auf der einen Seite (Nullstellung) blinde Lamellen b', auf der anderen Seite (Endstellung) ein Isolierstück J angeordnet. Die Anordnung der blinden Lamellen B ist zur Herstellung einer genügenden Bewegungsfreiheit für den Bürstenträger R in der Nullstellung erforderlich. Bei Bewegung des Bürstenträgers R von den Fahrlamellen zu den Bremslamellen wird durch eine entsprechende Kupplung mit Leistungsschützen auf der oder den letzten Fahrlamellen die Fahrschaltung aufgelöst und die Bremsschaltung hergestellt, so daß die eigentliche Leistungsschaltung nicht am Kollektor zu erfolgen braucht. In den Endstellungen wird die Bewegung des Bürstenträgers durch Anschläge A aus nachgiebigem Baustoff gehemmt.The collector IL is designed as an inner collector. The single ones Slats are labeled L. Between the driving and brake slats are on the one side (zero position) blind slats b ', on the other side (end position) an insulating piece J is arranged. The arrangement of the blind slats B is for production Sufficient freedom of movement for the brush holder R in the zero position is required. When the brush holder R moves from the travel slats to the brake slats by means of a corresponding coupling with contactors on the last Driving slats disengaged the driving gear and established the braking circuit, so that the actual power switching does not have to take place at the collector. In the end positions, the movement of the brush holder is made flexible by stops A Building material inhibited.
