Abstract

Die Erfindung betrifft einen Summenleistungsregler für mehrere hydrostatische Kolbenmaschinen (5, 5', 5'') und einen Druckmittler zum Erzeugen eines gemeinsamen Regelparameters, wobei die Fördervolumen der hydrostatischen Kolbenmaschinen (5, 5', 5'') mittels Verstellvorrichtungen (8, 9, 8', 9', 8'', 9'') einstellbar ist und die hydrostatischen Kolbenmaschinen (5, 5', 5'') ein Druckmittel in Arbeitsleitungen (6, 6', 6'') fördern. Die Verstellvorrichtungen (8, 9, 8', 9', 8'', 9'') werden durch eine Hyperbelregelvorrichtung (7, 7', 7'') geregelt und der Arbeitsdruck der hydrostatischen Kolbenmaschinen (5, 5', 5'') einem Druckmittler (12) zugeführt. Für jede Verstellvorrichtung (8, 9, 8', 9', 8'', 9'') der hydrostatischen Kolbenmaschinen (5, 5', 5'') ist eine separate Hyperbelregelvorrichtung (7, 7', 7'') vorgesehen, die einen Regelkolben (41, 41', 41'') und einen Meßkolben (11, 11', 11'') umfaßt, wobei der Meßkolben (11, 11', 11'') durch eine Axialkraft vorbelastet ist, welche auf den Regelkolben (41, 41', 41'') übertragbar ist, und der eine Kraft entgegengerichtet ist, die durch einen von dem Druckmittler (12) gemittelten Druck an einer Meßkolbenfläche (37, 37', 37'') erzeugt wird.
