Abstract

Ein Hydrauliksystem für ein hydraulisch betätigtes, automatisches Getriebe, insbesondere für ein Kegelscheibenumschlingungsgetriebe, enthält eine Pumpe (62) zur Bereitstellung von Hydraulikdruck in einer mit einem Stellventil (76) verbundenen Versorgungsleitung (68), die über ein Vorsteuerventil (82) mit einer Steuerleitung (80) verbunden ist, in der ein Steuerventil (84) angeordnet ist, mit der der die Stellung des Übersetzungsstellventils bestimmende Druck in der Steuerleitung einstellbar ist, und eine mittels eines von einem Antrieb der Pumpe getrennten Hilf santriebs (94) antreibbare Hilfspumpe (96), deren Ausgangsleitung über ein in Richtung der Steuerleitung öffnendes erstes Ventil (106) mit der Steuerleitung und über ein in Richtung der Versorgungsleitung öffnendes zweites Ventil (110) mit der Versorgungsleitung verbunden ist.
