Um bei besonders schnellfahrenden. Eisenbahnfahrzeugen das Schleifen der Räder bei zu starker Bremsverzögerung zu vermeiden, ist es erforderlich, daß bei abnehmender Geschwindigkeit der Bremsdruck entsprechend ermäßigt wird.To with particularly fast moving. Railway vehicles grind the wheels To avoid excessive braking deceleration, it is necessary that with decreasing speed the brake pressure is reduced accordingly.
Die vorliegende Erfindung besteht in einemThe present invention consists in one
von der Fahrgeschwindigkeit beeinflußten Bremskraftregler, der dieser Bedingung Rechnung trägt und bei Luftbremsen verschiedenster Art Verwendung finden kann.influenced by the driving speed Brake force regulator that takes this condition into account and a wide variety of air brakes Art can be used.
Die Erfindung beruht darin, daß der Bremskraftregler den Leitungsauslaß am Führerbremshahn derart überwacht, daß bei Überschreitung einer vorherbestimmten Bremsverzögerung dieser Auslaß . geschlossen und eine weitere Zunahme der Bremskraft verhindert wird.The invention is based on the fact that the brake force regulator has the line outlet on the driver's brake valve monitored in such a way that when a predetermined braking deceleration is exceeded this outlet. closed and a further increase in braking force is prevented will.
Eine beispielsweise Ausführungsform des neuen Bremskraftreglers ist in den Fig. 1 bis 3 veranschaulicht, und zwar zeigt:An example embodiment of the new brake force regulator is shown in FIG. 1 to 3, namely shows:
Fig. ι den Führerbremshahn im Schnitt inFig. Ι the driver's brake valve in section in
Verbindung mit dem Hauptluftbehälter, der Hauptleitung und dem als Auslaßbehälter dienenden Bremszylinder mit geöffnetem Pendelreglerventil in der Bremsstellung.Connection to the main air tank, the main line and the outlet tank Serving brake cylinder with open pendulum control valve in the braking position.
Fig. 2 zeigt den Führerbremshahn in der Lösestellung undFig. 2 shows the driver's brake valve in the release position and
Fig. 3 das Pendelreglerventil in geschlossenem Zustand.3 shows the pendulum control valve in the closed state.
Die Ausströmöffnung am Führerbremshahn α mündet nicht wie bisher ins Freie, sondern in den Bremszylinder b für die Lokomotivbremse, dessen Inhalt zur Hervorrufung der notwendigen Druckminderung in der Leitung für eine gewöhnliche Schnellbremsung genügt.The outflow opening on the driver's brake cock α does not open into the open as before, but into the brake cylinder b for the locomotive brake, the content of which is sufficient to produce the necessary pressure reduction in the line for normal rapid braking.
Zwischen dem Auslaß des Führerbremshahns und dem Bremszylinder b ist das Rückschlagventil m und vor demselben das Auslaßventil c angeordnet, das durch den Pendelregler d während der Fahrt offen gehalten wird.The check valve m is arranged between the outlet of the driver's brake cock and the brake cylinder b , and the outlet valve c in front of it, which is kept open by the pendulum controller d while driving.
Wird bei einer Bremsung die zulässige, durch entsprechende Belastung des Pendels vorherbestimmte Bremsverzögerung überschritten, so schlägt der Pendelregler d so weit nach vorn, daß das Ventil c die Ausströmung aus der Leitung hinter dem geöffneten Führerbremshahn α unterbricht, eine weitere Zunahme der Bremswirkung mithin verhindert.If the permissible braking delay, predetermined by the corresponding load on the pendulum, is exceeded during braking, the pendulum controller d strikes so far forward that the valve c interrupts the flow from the line behind the open driver's brake valve α , thus preventing a further increase in the braking effect.
Bei abnehmender Bremsverzögerung schlägt der Pendelregler d wieder zurück, wodurch das Ventil c geöffnet wird und eine weitere Druckabnahme in der Leitung, also eine Verstärkung der Bremskraft, erfolgt. Um hierbei ein Feststellen der Achsen mit der abnehmenden Geschwindigkeit zu verhindern, können die Bremszylinder mit Einrichtungen versehen sein, die eine entsprechende Abnahme des Bremsdruckes herbeiführen.When the braking delay decreases, the pendulum regulator d strikes back again, as a result of which the valve c is opened and there is a further decrease in pressure in the line, that is to say an increase in the braking force. In order to prevent the axes from locking at the decreasing speed, the brake cylinders can be provided with devices that bring about a corresponding decrease in the brake pressure.
