Description

Steuerung für einen zentral angeordneten#'f schalter elektrisch beiriebener Fahrzeuge Triebwagen elektrischer Bahnen erhalten häufig nur einen Fahrschalter, der unterhalb desWagens angeordnet und von beiden Wagenenden aus üb#er mechanische Übertragungsglieder betätigt wird. Bei einem unmittelbar von Hand zu bedienenden Fahrschalter bereitet die genaue Einhaltung der Schaltstellungen keine Schwierigkeiten, denn eine mit der Fahrschalterwelle verbundene Rastenscheibe gibt dem Fahrer das- sichere Gefühl, eine gerastete Schaltstellung richtig gefaßt zu haben. Anders jedoch, wenn der unter dem Wagen befindliche Fahrschalter von den 'Wagenenden aus geschaltet werden soll, denn die notwendigen Übertragungsglieder bringen zusätzliche Reibung toten Gang und Durchfederung zwischen Fahrschalter und Bedienungskurbel hinein, so daß dem Fahrer das sichere Gefülil fü# die Einhaltung der Schaltstellungen verlorengeht. Hierfür ist es gleichgültig, ob die Fahrschalter- oder die Bedienungswelle gerastet wird.Control for a centrally arranged switch for electrically operated vehicles Railcars of electric railways often only have one travel switch, which is arranged below the car and operated from both ends of the car via mechanical transmission elements. In the case of a drive switch that can be operated directly by hand, the exact adherence to the switch positions does not cause any difficulties, because a detent disk connected to the drive switch shaft gives the driver the secure feeling of having correctly grasped a locked switch position. It is different, however, if the drive switch located under the car is to be switched from the ends of the car, because the necessary transmission elements bring additional friction into the dead gear and spring deflection between the drive switch and the operating crank, so that the driver loses the safe feeling of maintaining the switch positions . For this it does not matter whether the drive switch or the operating shaft is locked.

Der vorstehend erwähnte Nachteil wird durch die erfindungsgemäße Steuerung vermieden, die darin besteht, daß durch Schließen eines Steuerstromkreises auf den Hauptstellungen des Fahrschalters die Welle der Bedienungskurbel des Fahrschalters abgebremst wird. In den Abbildungen ist ein Ausführungsbeispiel des Erfindungsgedankens -veranschaulicht.The above-mentioned disadvantage is caused by the control of the present invention avoided, which consists in that by closing a control circuit on the Main positions of the drive switch the shaft of the control crank of the drive switch is braked. In the figures is an embodiment of the inventive concept - illustrates.

Auf der in Abb. i mit A bezeichneten Welle des Fahrschalters ist in üblicher Weise die Rastensc ' heibe B befestigt, deren Raste C beim Einfallen, d. h. bei Erreichung der betreffenden Schaltstellung, die Kontakte D, D, schließt. Die Fahrschalterwelle ist über die mechanische Übertragung E mit der die Bedienungskurb#el tragenden Welle F verbunden. Auf der Welle F sitzt die runde Scheibe G, die durch den Schuh H gebremst wird, wenn der Magnet J aus der Stromquelle K Strom erhält. Dies ist jedesmal der Fall, wenn die Raste C eingefallen, als& die genaue Schaltstellung erreicht ist. Die vom Schuh H ausgeübte Bremswirkung ist hierbei gerade ausreichend, den Fahrer an einem unwillkürlichen Weiterschalten zu hindern; sie kann durch geringe Verstärkung des Handdruckes leicht überwunden werden.On the designated in Fig. I where a shaft of the driving switch in the usual manner the Rastensc 'Heibe B is mounted, the detent C with incidence, d. H. when the relevant switch position is reached, contacts D, D close. The travel switch shaft is connected to the shaft F carrying the operating crank via the mechanical transmission E. The round disk G sits on the shaft F and is braked by the shoe H when the magnet J receives power from the power source K. This is the case every time the detent C has fallen when & the exact switch position has been reached. The braking effect exerted by the shoe H is just sufficient to prevent the driver from involuntarily shifting further; it can easily be overcome by slightly increasing the hand pressure.

Die Abb.:2 veranschaulicht die Stellung der einzelnen Steuerelemente, wenn sich der Fahrschalter zwischen zwei Rasten befindet.Fig. 2 illustrates the position of the individual control elements, when the drive switch is between two notches.
