Mehrere Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und in der nachfolgenden Beschrei- " bung näher erläutert. Es zeigen: Figuren 1 bis 3 einen Teil einer Bremsanlage mit einem an sich einkreisigen Arbeitszylinder mit zweikreisiger Ansteuerung und Figur h und 5 einen zweikreisig angesteuerten Arbeitszylinder.Several embodiments of the invention are illustrated in the drawing and bung in the following description "explained in more detail show:. 1 to 3 show a part of a brake system with a single circuit to be working cylinder with dual-circuit control and figure h and 5 a two-circuit driven working cylinder.
Beschreibung der AusführungsbeispieleDescription of the exemplary embodiments
Eine mit Signalgebern, z.B. mit einer fußbetätigten Doppel-Einrichtung eingeleitete zweikreisige Ansteuerung wird über zwei Leitungen 1 und 2 einem ODER-Glied 3 zugeleitet. Vom ODER-Glied 3 führt eine Leitung k zu einem Relais 5, an das seitlich über eine Vorratsleitung β ein Vorratsbehälter T angeschlossen ist. Vom Relais 5 führt eine Arbeitsleitung 8 zu einem einkreisigen Arbeitszylinder Dieser Arbeitszylinder 9 kann ein Bremszylinder einer Druckluft-Bremsanlage sein.A two-circuit control initiated with signal transmitters, for example with a foot-operated double device, is fed to an OR element 3 via two lines 1 and 2. A line k leads from the OR element 3 to a relay 5 to which a storage container T is connected laterally via a storage line β. A working line 8 leads from the relay 5 to a single-circuit working cylinder. This working cylinder 9 can be a brake cylinder of a compressed air brake system.
Wenn über die zwei Leitungen 1 und 2 Signale zum ODER-Glied 3 gelangen, wählt das ODER-Glied je nach Bedarf das schnellste oder das größte Signal aus und gibt es über di'e Leitung h an das Relais 5. Das Relais 5 dient zur Mengenverstärkung. Es hatte vorher die Vorratsleitung 6 abgeschlossen und die Arbeitsleitung an eine Entlastungsstelle angeschlossen. Nun schaltet es um, undWhen signals arrive at the OR element 3 via the two lines 1 and 2, the OR element selects the fastest or the largest signal as required and sends it to the relay 5 via the line h . The relay 5 is used for Quantity amplification. It had previously closed supply line 6 and connected the working line to a discharge point. Now it switches over, and
verbindet - unter Abschluß der Entlastungssteile - die Vorratsleitung β mit der Arbeitsleitung 8. Der Arbeitszylinder 9 wird auf kurzem Wege mit Luft aus dem Vorratsbehälter 7 beschickt. -connects - with the conclusion of the relief parts - the Supply line β with the working line 8. The working cylinder 9 is charged with air from the storage container 7 over a short distance. -
Auf diese Weise wird der Arbeitszylinder 9 schnell und sicher betätigt. Die Ansteuerung über die Leitungen 1 und/cder 2 kann hydraulisch, pneumatisch oder elektrisch durchgeführt werden.In this way, the working cylinder 9 becomes fast and safely operated. The control via the lines 1 and / cder 2 can be hydraulic, pneumatic or electric be performed.
Die Figur 2 zeigt eine Bauart, bei der in einem ODER-Schaitglied 10 ein aus zwei Relaisgliedern 11 und 12 bestehendes Relais 11/12 angeordnet ist. Die Glieder 10, 11 und 12 sind Teile eines Mengenverstärkers 13.FIG. 2 shows a type in which in an OR switching element 10 a relay 11/12 consisting of two relay elements 11 and 12 is arranged. The links 10, 11 and 12 are parts of a quantity amplifier 13.
Wenn über die beiden Leitungen 1 und 2 Signale zu dem Mengenverstärker 13 gelangen,, sind die b'eiden Relaisglieder 11 und 12 über die ODER-Verknüpfung auswählbar und nur die schneller oder stärker durchgeführte Verstärkung gelangt über die Arbeitsleitung 8 zum Arbeitszylinder 9-When signals reach the quantity amplifier 13 via the two lines 1 and 2, the two are relay elements 11 and 12 can be selected via the OR link and only the faster or more powerful reinforcement reaches the working cylinder 9 via the working line 8
Ir. der Figur 3 ist eine Variante dargestellt, bei der zwei Relaisglieder 1h und 15 vor dem ODER-Glied 16 angeordnet sind, das über zwei Leitungen 17 und 18 von dem Mengenverstärker beschickbar ist.Ir. the figure 3 is shown a variant h at the two relay contacts 1 and 15 are arranged in front of the OR gate 16, which via two lines 17 and 18 can be charged by the amount of amplifier.
Wenn die beiden Leitungen 1 und 2 Signale liefern, werden die Relaisglieder 1 it und 15 umgeschaltet, und es fließen - vom Vorratsbehälter 7 gespeist - zwei Mengenströme über die Leitungen 17 und 13 zum ODER-Glied 16.

Die Figur U zeigt eine etwas andere Bauart. Hier ist eir. zweikreisiger Arbeitszylinder 20 mit integrierter ODER-Funktion verwendet. Wie beim Ausführungsbeispiel nach der Figur 3 sind auch hier zwei Relaisglieder 1h und 15 verwendet, welche die Leitungen IT und 18 mit Mengenströmen beschicken. Die beiden Mengenströme werden dem zweikreisigen Arbeitszylinder 20 zugeführt, der mit seinem integrierten ODER-Glied den jeweils höheren oder schneller ankommenden Druck bzw. ein entsprechendes Signal auswählt und mit diesem den Arbeitszylinder betätigt.The figure U shows a slightly different design. Here is one. two-circuit working cylinder 20 with an integrated OR function is used. As here two relay elements 1 are h in the embodiment according to FIG 3 and uses 15 which feed the lines IT and 18 with flow rates. The two mass flows are fed to the two-circuit working cylinder 20, which with its integrated OR element selects the higher or faster arriving pressure or a corresponding signal and actuates the working cylinder with it.
Die Figur 5 zeigt schließlich, daß es bei einer Arbeitszylinderbauart, wie sie in Figur h dargestellt ist, auch möglich ist, den Arbeitszylinder 20 mit einem über die Leitung 2 gesteuerten Kreis direkt mit einem Signal zu beschicken und nur den einen, anderen Kreis mit einer Verstärkung über ein Relais 23 zu versehen.Finally, FIG. 5 shows that with a working cylinder design as shown in FIG. H , it is also possible to feed the working cylinder 20 with a circuit controlled via the line 2 directly with a signal and only one, the other circuit with one To provide amplification via a relay 23.
Auch bei einer solchen Bauart werden zwei Ströme dem Arbeitszylinder 20 zugeführt, der mit seinem integrierten ODER-Glied den jeweils höheren oder schneller ankommenden Druck oder ein entsprechendes Signal auswählt und mit diesem den Arbeitszylinder betätigt.With such a design, too, two streams are fed to the working cylinder 20, the one with its integrated OR element selects the higher or faster arriving pressure or a corresponding signal and with this actuates the working cylinder.
