Description

Vorrichtung zum Auslösen festgebremster Achsen an Schienenfahrzeugen Die Erfindung bezieht sich auf eine Vorrichtung zum Auslösen festgebremster Achsen an Schienenfahrzeugen, bei der ein Behälter zur Anwendung kommt, der während der Fahrt durch einen von einer Bremsachse angetriebenen Regler entsprechend der Geschwindigkeit aufgeladen wird und beim Festbremsen der Achsen die Dauer der Bremszylinderentlüftung maßgebend beeinflußt. Die im Patent 7z9 834 beschriebene Vorrichtung zur zusätzlichen Entlüftung des genannten Behälters, durch die die Dauer der Bremszylinderentlüftung auf das unbedingt notwendige Maß verkürzt wird, soll gemäß der Erfindung dadurch weiter verbessert werden, daß nach dem erneuten Umlaufen der festgebremst gewesenen Achsen der Druck im Bremszylinder nicht wieder steil, sondern allmählich ansteigt, um mit Sicherheit ein erneutes Feststellen der Bremsachsen zu verhindern.Device for releasing locked axles on rail vehicles The invention relates to a device for releasing locked axles on rail vehicles in which a container is used, which during the Travel through a controller driven by a brake axle according to the speed is charged and when the axles are locked, the duration of the brake cylinder ventilation decisively influenced. The device described in the patent 7z9 834 for additional Venting of the said container, through which the duration of the brake cylinder venting Is shortened to the absolutely necessary extent, according to the invention thereby can be further improved that after the renewed rotation of the braked Axes the pressure in the brake cylinder does not rise again steeply, but increases gradually, to be sure to prevent the brake axles from locking again.

Ein Ausführungsbeispiel zur Verwirklichung des Erfindungsgedankens ist auf der Schemazeichnung dargestellt.An embodiment for realizing the idea of the invention is shown on the schematic drawing.

Beim Festbremsen der Achse wird durch die bekannte Regelvorrichtung der Stromkreis für das elektropneumatische Venti122 geschlossen. Der Magnetkern wird nach oben gezogen und verbindet dabei die an eine Druckluftquelle angeschlossene Leitung 31 mit dem Raum unterhalb des Kolbens 25. Der gesamte Kolbensatz 23, 24, 25 wird umgesteuert, wodurch die Verbindung der Bremszylinderleitung x9 mit der Speiseleitung 2o unterbrochen und diejenige mit der Entlüftung 21 hergestellt wird. Der schon erwähnte Behälter 9 wird über die Leitung 32 entlüftet. Zu dieser aus dem Vorpatent bekannten Einrichtung treten erfindungsgemäß die Teile 26 bis 30, wodurch folgende Wirkung erzielt wird.When the axle is braked, the known control device the circuit for the electro-pneumatic valve 122 is closed. The magnetic core is pulled up and connects the one connected to a compressed air source Line 31 with the space below the piston 25. The entire piston set 23, 24, 25 is reversed, whereby the connection of the brake cylinder line x9 with the Feed line 2o interrupted and the one with the vent 21 is established. The already mentioned container 9 is vented via line 32. To this one out the device known from the previous patent, according to the invention, the parts 26 to 30, whereby the following effect is achieved.

Die Beaufschlagung des Kolbens 25 trifft über das Rückschlagventil 26 auch den Kolben 27, der bei seiner Linksverschiebung die Durchgangsöffnung des Hahnes 28 abdrosselt; die Bremszylinderentlüftung kann trotzdem ungehindert über das Rückschlagventil2g, Leitung z9, Ventil 23 und Auslaß 21 vor sich gehen. Für den erneuten Druckanstieg im Bremszylinder über 2o, 23, 19 steht dagegen nur der gedrosselte Durchgang des Hahnes 28 zur Verfügung, dessen Drosselung durch den nach Maßgabe der Ausströmung der Druckluft über die Düse 3o nach rechts zurückgehenden Kolben27 nur allmählich aufgehoben wird.The piston 25 is acted upon via the check valve 26 also the piston 27 which, when it is shifted to the left, opens the passage opening of the Hahnes 28 throttles; the brake cylinder ventilation can still be unhindered the check valve 2g, line z9, valve 23 and outlet 21 go ahead. For the renewed increase in pressure in the brake cylinder above 2o, 23, 19, on the other hand, is only available throttled passage of the valve 28 available, whose throttling by the after According to the outflow of the compressed air via the nozzle 3o going back to the right Piston27 is only gradually lifted.
