| Abstract: |
(EN) The invention relates to a hydraulic arrangement for controlling a continuously variable conical disc transmission having a variably adjustable transmission ratio of a motor vehicle. Said hydraulic system comprises: a first valve arrangement for maintaining the contact pressure of the continuously variable conical disc transmission; a second valve arrangement for controlling the transmission ratio of the continuously variable conical disc transmission; a hydraulic energy source for supplying the hydraulic arrangement with hydraulic energy. The hydraulic arrangement also comprises a third valve arrangement for controlling a forward coupling and a reverse coupling in order to improve said hydraulic arrangement. (DE) Die Erfindung betrifft eine Hydraulikanordnung zur Steuerung eines Kegelscheibenumschlingungsgetriebes mit einem variabel einstellbaren Übersetzungsverhältnis eines Kraftfahrzeuges, mit: einer ersten Ventilanordnung zur Sicherstellung eines Anpressdrucks des Kegelscheibenumschlingungsgetriebes, einer zweiten Ventilanordnung zur Steuerung des Übersetzungsverhältnisses des Kegelscheibenumschlingungsgetriebes, einer hydraulischen Energiequelle zur Versorgung der Hydraulikanordnung mit hydraulischer Energie. Um eine verbesserte Hydraulikanordnung bereitzustellen, weist diese eine dritte Ventilanordnung zur Steuerung einer Vorwärtskupplung und einer Rückwärtskupplung auf. | ||||||||||||||||||||||||||||||||||||||||
