Description

Verfahren und Einrichtung frequenzgesteuerter geschlossener Regel - und Steuerkreise mit Volumenrückführung Beschreibung Wird in einem geschlossenen hydraulischen Druckregelkreis - insbesondere bei Bremskreisen von Fahrzeugen - die Bremskolbenanlage wiederholt betätigt, dann verschiebt sich der Bremskolben infolge der Bremsbelagabnützung und es entsteht - sofern die Bremsanlage nach dem Bremsvorgang in die Ausgangslage zurückgeht - eine Volumenvergrößerung des Bremskreises, wenn die Riickstellung des Bremskolbens begrenzt ist.Procedure and establishment of frequency-controlled closed rule and control circuits with volume feedback Description Used in a closed hydraulic pressure control circuit - especially in vehicle brake circuits - the Brake piston system actuated repeatedly, then the brake piston shifts as a result the brake pad wear and it occurs - if the brake system is after the braking process goes back to the starting position - an increase in the volume of the brake circuit, if the return position of the brake piston is limited.

Soll aber das Bremssystem stets aus der Ruhelage, die unverwandert sein soll, betätigbar sein, dann muß entsprechend der Volumenvergrößerung des Bremsvolumens Bremsö1 nachströmen, ohne das das Bremssystem geöffnet wird.But should the braking system always move from the rest position, which remains unchanged should be, be actuatable, then must be according to the volume increase of the braking volume Flow in brake oil without opening the brake system.

Die nachfolgend beschriebene Einrichtung stellt eine Mach-und Rückströmeinrichtung der oben beschriebenen Bedingung dar.The device described below represents a Mach and backflow device the condition described above.

Die Kugel (1) einer vorzugsweise als Kugelventil ausgebildeten Strömungseinrichtung wi-d durch die Feder (2) gegen die Schließkante gedrückt, so daß vom Ölvorratsraum (3) kein Bremsöl in den Bremskreis (4) gelangen kann. Entsteht durch die Nachstellung des Bremskolbens (5) im Bremskreis eine Volumenvergrößerung gegenüber dem Druckkolben (6), so öffnet sich dann beim Zurückgehen des Kolbens (6) in seine Ausgangslage das Kugelventil infolge des Unterdruckes iwd es strömt Bremsöl nach, bis der Druckausgleich zwischen Ölraum (3) irnd Bremsleitung (4) eintritt.The ball (1) of a flow device preferably designed as a ball valve wi-d pressed against the closing edge by the spring (2), so that from the oil reservoir (3) no brake oil can get into the brake circuit (4). Arises from the reenactment of the brake piston (5) in the brake circuit increases in volume compared to the pressure piston (6) then opens when the piston (6) goes back into its starting position the ball valve as a result of the negative pressure iwd it flows in brake oil until the pressure equalization between the oil chamber (3) and the brake line (4).

Danach wird durch die leichte Federkraft der Feder (2) der Bremskreis geschlossen. fs tritt also das Schließen des Bremskreises nicht erst bei Betätigung des Bremssystems ein.The brake circuit is then activated by the light spring force of the spring (2) closed. So the closing of the brake circuit does not only occur upon actuation of the braking system.

Wird nach einer Vollständigen Abnützung eines Bremsbelages notwendig, daß der Bremskolben (5) in seine Ursprungsstellung für einen neuen Bremsbelag zurückgeschoben werden muß, dann muß der Öffnungsstift (7) gegen die Ventilkugel (1) so wei.t gedreht werden, daß das rüclfliessende Bremsöl, ohne daß sich d?s Rückschlagve- til schließt, wieder tn den Vorratsraum (3) gelangen kann. If a brake lining becomes necessary after complete wear, that the brake piston (5) is pushed back into its original position for a new brake lining then the opening pin (7) must be turned against the valve ball (1) as far as possible that the return-flowing brake oil without the non-return valve closing, can reach the storage space (3) again.

Nach Beendigung dieses Vorganges muß der Öffnungstift (7) wieder in seine Lösungslage zurückgedreht werden. After completing this process, the opening pin (7) must again be turned back into its solution position.
