    摘要： A belt-driven conical-pulley transmission contained in the power train of a motor vehicle and having two conical disk pairs encircled by an endless torque-transmitting element. A hydraulic system is provided for pressing the conical surfaces of the conical disks against the endless torque-transmitting means and for opposite adjustment of the spacing between the conical disks for an adjustment of the transmission ratio. The hydraulic system includes a pump driven by an internal combustion engine that propels the vehicle, and the system includes an auxiliary oil source with which a predetermined minimum pressure is maintained in the hydraulic system when the internal combustion engine is shut off.

    摘要： A hydraulic arrangement by which a plurality of shift rails of a transmission are actuated, including one double acting cylinder per shift rail by which the respective shift rail can be moved back and forth. A first hydraulic valve is connected upstream of the plurality of shift rails and has a first output and a second output, by which a first shift pressure and a second shift pressure for actuating the shift rails can be provided. A second hydraulic valve is connected between the first hydraulic valve and two of the shift rails, and by which it is selectively possible for the first output of the first hydraulic valve to be associated with one of the double acting cylinders of the two shift rails, and the second output of the first hydraulic valve to be associated with the other double acting cylinder of the two shift rails.

    摘要： A positive-displacement pump having an eccentrically positioned internal ring gear and pinion within a pump housing. Pressurized operating fluid is provided by the pump to actuate an actuation piston of a clutch unit, such as a double clutch unit. The clutch unit is drivingly coupled with the pump for movement between engaged and disengaged positions. At least one throughbore is provided in the pump housing within which throughbore the clutch actuation piston is guided.
