Description

Die Erfindung will die im Patent 698 858 beschriebene Vorrichtung zum Auslösen festgebremster Achsen von Schienenfahrzeugen durch die Verbindung mit einer Schleuderschutzvorrichtung, durch die bekanntlich das nicht nur beim Anfahren, sondern überhaupt bei allen Geschwindigkeiten beim Überschreiten der Adhäsionsgrenze eintretende Schleudern der Antriebsräder vermieden werden soll, für die Verwendung an Lokomotiven und Triebfahrzeugen besonders geeignet machen. Erfindungsgemäß wird zur Steuerung der Schleuderschutzvorrichtung der gleiche Fliehkraftregler benutzt, der die bekannte Vorrichtung zum Auslösen der festgebremsten Achsen steuert, so daß das erstrebte Ziel mit nur wenigen zusätzlichen Teilen erreicht wird.The invention seeks the device described in the patent 698 858 for releasing the braked Axles of rail vehicles through the connection with an anti-skid device, by which, as is well known, not only when starting, but at all speeds when exceeding skidding of the drive wheels occurring at the adhesion limit is to be avoided, make it particularly suitable for use on locomotives and traction vehicles. According to the invention, the same centrifugal governor is used to control the anti-skid device used, which controls the known device for triggering the braked axles, so that the desired goal with only a few additional parts is achieved.

Die zu der bekannten Vorrichtung hinzukommenden Teile sind der Kolben 37 mit der Düsenbohrung 38, die Feder 39, der Behälter 40, das Doppelventil 41«, 41s und das Schaltventil 42.The parts that are added to the known device are the piston 37 with the nozzle bore 38, the spring 39, the container 40, the double valve 41 ″, 41 s and the switching valve 42.

Die Wirkungsweise der Schleuderschutzvorrichtung ist folgende:The operating principle of the anti-skid device is as follows:

J5 Bei den normalen Beschleunigungen, die etwa o,5m/Sek.2 betragen, füllt sich der Raum rechts vom Kolben 37 einschließlich Behälter 40 durch die Düse 38 so gleichmäßig mit dem auf die linke Seite des Kolbens 37 wirkenden Reglerdruck auf, daß der Kolben 37 dank der Feder 39 das Ventil 41* geschlossen und das Ventil 4ie geöffnet hält. Steigt die Beschleunigung hingegen über dieses Maß z. B.J 5 At normal accelerations, which are about 0.5 m / sec. 2 , the space to the right of the piston 37 including the container 40 fills through the nozzle 38 so evenly with the regulator pressure acting on the left side of the piston 37 that the piston 37, thanks to the spring 39, closes the valve 41 * and the valve 4i e holds open. If, however, the acceleration rises above this level z. B.

bei Beginn des Schleudems, so wandert der Kolben 37 unter der Einwirkung des plötzliehen Druckluftanstieges auf seiner linken Seite, der hervorgerufen wurde durch das von dem Regler 1 hierbei weit geöffnete Ventil 4", nach rechts, öffnet das Ventil 41*, nachdem vorher das Ventil 41" geschlossen wurde, und läßt Druckluft in das Schaltventil 42 eintreten. Dieses Schaltventil betätigt je nach den vorliegenden Verhältnissen die Sandstreuanlage oder nimmt in an sich bekannter Weise die Antriebskraft weg.at the beginning of the spin, the piston 37 moves under the action of the sudden Compressed air rise on its left side, which was caused by the valve 4 "opened wide to controller 1, to the right, the valve 41 * opens after the valve 41 ″ has previously been closed, and allows compressed air to enter the switching valve 42. This switching valve operates depending on the existing conditions the sand spreading system or takes in itself known Dispose of the driving force.

Die Einstellbarkeit dieser Vorrichtung auf eine bestimmte Beschleunigung ermöglicht es, schon so zeitig beim Schlupfbeginn einzugreifen, daß der Schleudervorgang gar nicht erst zur vollen Entfaltung kommt.The adjustability of this device to a certain acceleration makes it possible intervene so early at the start of the hatch that the spinning process does not take place at all only comes to full development.
