Abstract
Conical disk pairs of a belt-driven conical-pulley transmission include an axially fixed disk and an axially movable disk that are situated on respective shafts on the input side and the output side and are connectable by an endless torque-transmitting component for transmitting torque. At least one of the shafts has at least one axial bore from which at least one connecting bore extends to the surface of the shaft. The outlet of the connecting bore is in a region that is covered by the movable disk independent of the latter's axial position. An annular chamber formed between the shaft outer surface and a radially inner surface of the axially movable disk can be subjected to hydraulic pressure through the connecting bore. A discharge groove is provided for bleeding air bubbles from the annular chamber.
