Description
Gegenstand des Patentes 1 026 348 ist ein Lastumschalter mit Sprungschaltwerk, insbesondere für Transformatoren auf elektrischen Triebfahrzeugen, bei dem das unter der Wirkung eines Kraftspeichers bewegte System aus wenigstens zwei Teilen mit sehr verschiedenen Trägheitsmomenten besteht, deren einer Teil (mit möglichst geringem Trägheitsmoment) die beweglichen Kontakte trägt bzw. betätigt, während der andere Teil (mit hohem Trägheitsmoment) einerseits so bemessen ist, daß der Umschaltvorgang in der gewünschten Zeit abläuft, und andererseits so angeordnet und gestaltet ist, daß die durch Schienenstöße, Anfahr- und Bremsvorgänge auftretenden Beschleunigungen ohne Einfluß auf den Ablauf des Umschaltvorganges bleiben.The subject of patent 1 026 348 is a diverter switch with snap switch, in particular for Transformers on electric locomotives, which act under the effect of an energy storage device moving system consists of at least two parts with very different moments of inertia, one of which Part (with the lowest possible moment of inertia) carries or operates the moving contacts while the other part (with a high moment of inertia) is dimensioned on the one hand so that the switching process in the desired time elapses, and on the other hand is arranged and designed so that the rail joints, Accelerations occurring when starting and braking have no effect on the sequence of the switching process stay.
Es hat sich herausgestellt, daß man die Anordnung nach dem Hauptpatent noch wesentlich verbessern kann, wenn man nach der Erfindung am Lastumschalter noch Mittel, z. B. Hebel, Räder od. dgl., vorsieht, die den mit höherem Trägheitsmoment ausgestatteten, vorzugsweise als Rotationskörper ausgeführten Teil so antreiben, daß er im gleichen Zeitelement einen größeren Winkelweg zurücklegt als das mit ihm gekoppelte und seine Bewegung bewirkende Glied des Schalters.It has been found that the arrangement according to the main patent can still be improved significantly can, if according to the invention at the diverter switch still means such. B. levers, wheels or the like., Provides, those equipped with a higher moment of inertia, preferably designed as a body of revolution Drive part in such a way that it covers a greater angular path than that with it in the same time element coupled and its movement causing member of the switch.
An Hand der Zeichnung sei ein Lastumschalter nach der Erfindung näher erläutert.A diverter switch according to the invention will be explained in more detail with reference to the drawing.
Fig. 1 und 2 zeigen in schematischer Darstellung sprunghaft betätigte Kniehebelschalter in Seitenansicht; in1 and 2 show a schematic representation of abruptly actuated toggle lever switches in a side view; in
Fig. 3 ist eine besondere Ausbildung eines Schwungkörpers wiedergegeben.Fig. 3 shows a special design of a flywheel.
Mitl und 2 sind in Fig. 1 die mit den Lagerwellen 3 und 4 fest verbundenen Kniehebel des Schalters angedeutet, die an ihren freien Enden durch eine Koppel 5, an der in üblicher Weise der nicht dargestellte Kraftspeicher eingehängt ist, verbunden sind. Der Schalterantrieb ist in der Zeichnung ebenfalls weggelassen, da dieser hinlänglich bekannt ist. Mit 6 und 7 sind die Schwungkörper bezeichnet. Diese sind drehbar auf den Lagerwellen 3 und 4 aufgesetzt. Eine Koppelstange 8, die als Schubstange wirkt, verbindet den Kniehebel 1 mit dem auf der ihm gegenüberliegenden Lagerwelle 4 aufgesetzten Schwungkörper 7. Die Einhängung der Schubstange 8 ist so gewählt, daß der Einhängepunkt 11 am Kniehebel 1 von der zugehörigen Lagerwelle 3 weiter entfernt liegt als der Einhängepunkt 80 am Schwungkörper 7 von dessen Lagerwelle 4. Die Schubstange 20 verbindet sinngemäß den Kniehebel 2 mit dem Schwungkörper 6. Infolge der verschieden großen Abstände der Einhängepunkte der Schubstangenenden von den zugeordneten Lagerstellen werden bei der Schalterumlegung in seine andere, in der Zeichnung gestricheltMitl and 2 are indicated in Fig. 1 with the bearing shafts 3 and 4 firmly connected toggle lever of the switch, which are connected at their free ends by a coupling 5, on which the energy storage device, not shown, is suspended in the usual way. The switch drive is also omitted in the drawing, as it is well known. With 6 and 7 the flywheels are designated. These are rotatably placed on the bearing shafts 3 and 4 . A coupling rod 8, which acts as a push rod connects the bell crank 1 with the on it opposite the bearing shaft 4 mounted flywheel body 7. The hanging system of the push rod 8 is chosen so that the mount 11 on the toggle lever 1 is located further away from the associated bearing shaft 3 as the suspension point 80 on the flywheel 7 of its bearing shaft 4. The push rod 20 analogously connects the toggle lever 2 with the flywheel 6. As a result of the different distances between the hang-in points, the push rod ends from the associated bearing points are dashed in the drawing when the switch is moved to its other

dargestellte Endstellung von den Kniehebeln 1 und 2 gegenüber den mit Hilfe der Schubstangen 8 und 20 mit bewegten Schwungkörpern 7 und 6 verschieden große Winkelwege zurückgelegt. Während, z. B. der Kniehebel 1 den Winkelweg Ct1 zurücklegt, hat sich der Schwungkörper 7 um den demgegenüber weit größeren Winkelweg a2 bewegt. Die bei der Umschaltbewegung auftretende größere Schwungwirkung erweist sich als günstig, weil dadurch der Schalter gegen die beim Fahrbetrieb auftretenden Erschütterungen und Beschleunigungen noch weit unempfindlicher wird. Außerdem können gegebenenfalls die Schwungmassen noch verkleinert und dadurch kann das Schaltergewicht gegenüber einem Schalter, bei dem die Schwungkörper mit dem Schalter fest verbunden sind, noch verringert werden.End position shown by the toggle levers 1 and 2 with respect to the angular paths of different sizes covered with the help of the push rods 8 and 20 with moving oscillating bodies 7 and 6. While, e.g. B. the toggle lever 1 covers the angular path Ct 1 , the oscillating body 7 has moved by the far larger angular path a 2. The greater swinging effect occurring during the switching movement proves to be favorable because it makes the switch even more insensitive to the vibrations and accelerations that occur during driving. In addition, the centrifugal masses can optionally be reduced even further, and thereby the weight of the switch can be further reduced compared to a switch in which the centrifugal bodies are firmly connected to the switch.
Die Erfindung läßt mannigfaltige Abwandlungen zu. So können z. B. an Stelle der Schubstangen auch Zahnradübersetzungen vorgesehen werden, durch die jeweils der einem Kniehebel gegenüberliegende Schwungkörper angetrieben wird. In diesem Fall braucht man, wie Fig. 2, in der gleiche Teile mit gleichen Bezugszeichen wie in Fig. 1 bezeichnet sind, zeigt, auf der einen Lagerwelle, z. B. der Lagerwelle 3, nur ein Zahnsegment 30 zu befestigen und dieses mit einem mit dem Schwungkörper 7 verbundenen Ritzel 70 kämmen zu lassen.The invention permits a wide variety of modifications. So z. B. instead of the push rods, gear ratios are also provided, through which each of the flywheel opposite a toggle lever is driven. In this case it is necessary, as in FIG. 2, in which the same parts are denoted by the same reference numerals as in FIG. B. the bearing shaft 3, to attach only one toothed segment 30 and to let this mesh with a pinion 70 connected to the flywheel 7.
Es ist empfehlenswert, wie in Fig. 3 dargestellt, den Schwungkörper 60 aus zwei oder mehreren Teilen verschieden großer Massen zu fertigen. In der Figur sind zwei Schwungkörperteile 61 und 62 vorgesehen.It is advisable, as shown in FIG. 3, to manufacture the flywheel 60 from two or more parts of different sizes. In the figure, two flywheel parts 61 and 62 are provided.
