Abstract

Die Erfindung betrifft eine hydraulische Fahrzeugbremsanlage (10) mit einem jedem Radbremszylinder (16, 18) vorgeschalteten Radbremsventil (20, 22) und je einer den Radbremsventilen (20, 22) parallel geschalteten Rückförderpumpe (28, 30), an deren Saugseiten die Radbremszylinder (16, 18) angeschlossen sind. Zur Blockierschutzregelung werden die Rückförderpumpen (28, 30) in Gang gesetzt und durch getaktete Ansteuerung eines Radbremsventils (20, 22) eines zum Blockieren neigenden Fahrzeugrades der Bremsflüssigkeitsdruck im Radbremszylinder (16, 18) dieses Fahrzeugrades moduliert. Zur Ausbildung einer Antriebsschlupfregeleinrichtung schlägt die Erfindung ein Umschaltventil (32) in einer Bremsleitung (14) vom Hauptbremszylinder (12) zum Radbremszylinder (18) eines angetriebenen Fahrzeugrades vor. Durch Schließen des Umschaltventils (32) und Antreiben der Rückförderpumpen (28, 30) läßt sich Bremsflüssigkeit aus dem Hauptbremszylinder (12) durch das Radbremsventil (20) des nicht angetriebenen Fahrzeugrades ansaugen und in den Radbremszylinder (18) des angetriebenen Fahrzeugrades fördern und dadurch eine Bremskraft erzeugen, um Durchdrehen des Fahrzeugrades zu vermeiden.
