Abstract

Die Erfindung geht aus von einer elektronisch druckregelbaren Hydraulikbremsanlage eines Fahrzeugs. Derartige Bremsanlagen (10) umfassen neben einem Hauptbremszylinder (12) zur Betätigung der Bremsanlage (10) mehrere Radbremsen (14) und ein Hydroaggregat (16) zur Modulation des Bremsdrucks an den Radbremsen (14) in Abhängigkeit kritischer Fahrzustände des Fahrzeugs. Das Hydroaggregat (16) ist dazu mit einem Druckerzeuger (60) mit ansteuerbaren Magnetventilen (46, 48, 54, 58, 68) und einem elektronischen Steuergerät (70) ausgestattet. Am Hydroaggregat (16) sind darüber hinaus Druckmittel führende Kanäle und hydraulische Anschlüsse (18, 20, 24, 26, 28, 30) ausgebildet. Erfindungsgemäße wird vorgeschlagen, bei einem konventionellen Hydroaggregat (16) mit 4 Anschlüssen (24, 26, 28, 30) für Radbremsen (14) an wenigstens einem dieser Anschlüsse (24, 26, 28, 30) einen hydraulischen Zusatzverbraucher (32) anzuschließen, wobei dessen Beaufschlagung mit hydraulischem Druck unabhängig von einer Betätigung der Radbremsen (14) erfolgen kann. Der Zusatzverbraucher (32) kann vorzugsweise eine Reibungskupplung sein, die ein Fahrzeug mit einem Anhänger verbindet und deren Zuspannkraft in Abhängigkeit des anliegenden hydraulischen Drucks veränderbar ist.
