Description

Die Erfindung betrifft eine weitere Verbesserung der im Patent 698 858 behandelten Vorrichtung zum Auslösen festgebremster Achsen von Schienenfahrzeugen.The invention relates to a further improvement on that dealt with in the '698,858 patent Device for releasing locked axles on rail vehicles.

An Hand der Zeichnung, die einen Ausschnitt aus der Zeichnung des Vorpatents darstellt, soll die erfindungsgemäß verbesserte Wirkungsweise der Vorrichtung erläutert werden.On the basis of the drawing, which is an excerpt from the drawing of the preliminary patent represents, the invention is intended to explain the improved mode of operation of the device will.

Nach der Abb. 1 ist die Vorrichtung gegenüber dem Vorpatent dadurch geändert, daß der Kolben 12 nach unten mit einer Kolbenstange 33 versehen ist, die an ihrem unteren Ende eine Winkelbohrung 34 aufweist.According to Fig. 1, the device is changed from the previous patent in that the piston 12 is provided with a piston rod 33 downwards, which at its lower Has an angled bore 34 at the end.

Abb. 2 zeigt eine gegenüber dem in Abb. 1 dargestellten Ausführungsbeispiel etwas geänderte Ausführungsform.Fig. 2 shows a slightly different from the embodiment shown in Fig. 1 Embodiment.

Die Wirkungsweise der geänderten Vorrichtung ist nun wie folgt:The mode of operation of the modified device is now as follows:

Kommt die Bremsachse beim Bremsen zum Gleiten, dann bewirkt der von dieser Achse angetriebene Fliehkraftregler, eine Entlüftung der Leitung 31 und damit des Raumes über dem Kolben 12, so daß der Kolben 12 nach oben getrieben wird und das Ventil 19 öffnet, worauf Druckluft aus der Leitung 30 in den Raum 21 tritt, die den Kolben 17 nach links verschiebt, der seinerseits ein Bremszylinderentlüftungsventil öffnet. Der Druck im Raum unterhalb des Kolbens 12 und damit auch der im Raum rechts vom Kolben 25 sowie im Behälter 9, der sich bisher nur über die Düse 8 dem beim Gleiten erniedrigten Druck im Raum oberhalb des Kolbens 12 angleichenIf the braking axis slides when braking, that of this axis causes driven centrifugal governor, a vent of the line 31 and thus of the room above the piston 12, so that the piston 12 after is driven up and the valve 19 opens, whereupon compressed air from the line 30 into the Space 21 enters the piston 17 to the left moves, which in turn opens a brake cylinder ventilation valve. The pressure in the room below the piston 12 and thus also in the space to the right of the piston 25 and in the Container 9, which so far has only been subjected to the reduced pressure when sliding via the nozzle 8 adjust in the space above the piston 12

konnte, wird nunmehr zusätzlich durch die Bohrung 34 in der Kolbenstange 33 erniedrigt. Hierdurch wird erreicht, daß der nach dem Wiederanlaufen der gleitenden Achse von deren Regler in dem Raum über dem Kolben 12 und damit auch in dem Raum links vom Kolben 25 aufgebaute Druck schnell den etwa noch vorhandenen Gegendruck auf diesen Kolben überwindet, so daß das Ventil 24 geöffnet wird, worauf der Kolben 17 wieder in die gezeichnete Stellung zurückgeht und der Bremszylinder von neuem gefüllt werden kann, wodurch die Gewähr gegeben ist, daß die wieder umlaufende Achsecould, is now additionally lowered through the bore 34 in the piston rod 33. This ensures that the sliding axis of its controller in the room after the restart the piston 12 and thus also in the space to the left of the piston 25 pressure built up quickly overcomes any counter pressure still present on this piston, so that the valve 24 is opened, whereupon the piston 17 returns to the position shown and the brake cylinder can be filled again, whereby the guarantee is given that the rotating axis again

ts ohne Verzug von neuem abgebremst wird.ts is braked again without delay.

Ein anderes Ausführungsbeispiel der Erfindung zeigt die Abb. 2.Another exemplary embodiment of the invention is shown in FIG. 2.

Hier nimmt der hochgehende Kolben 12 ein mit ihm verbundenes Ventil 3 5 mit, wodurch eine Kammer 36 geöffnet wird, die den Druck unterhalb des Kolbens 12 schnell um einen gewissen Betrag erniedrigt.Here the rising piston 12 takes a valve 3 5 connected to it with it, as a result of which a chamber 36 is opened, which increases the pressure below the piston 12 quickly decreased by a certain amount.

Damit die Vorrichtung genau so sicher anspricht wie bisher, ist darauf zu achten, daß die Bohrung 34 in Abb. 1 bzw. das Ventil 3 5 in Abb. 2 erst wirksam werden, nachdem das Ventil 19 schon geöffnet ist.So that the device responds just as reliably as before, it must be ensured that the hole 34 in Fig. 1 and the valve 3 5 in Fig. 2 only become effective after the Valve 19 is already open.
