Abstract: A volume flow regulating valve for a hydraulic system for controlling a belt-driven conical-pulley transmission. The valve includes a control piston with a pressure surface and an oppositely facing pressure return surface. A supply segment is associated with the pressure surface, and a cooler return segment is connectable with the supply segment by a control edge of the control piston. A pressure return segment is associated with the pressure return surface, and a pressurizing segment is situated between the cooler return segment and the pressure return segment.

Abstract: A conical pulley assembly with integrated torque sensor. A torque-dependent force is transmitted through a transmitting component to a sensing piston whose position determines the pressure in a sensing chamber. The transmitting member is connected to the movable disk, and is formed in such a way that it transmits the torque-dependent force to the sensing piston in a manner that is dependent on the position of an axially movable disk of the conical pulley.

Abstract: 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.

Abstract: A hydraulic system for an automatic transmission operatively connected to an internal combustion engine that is operable in a start-stop mode. The hydraulic system includes a hydraulic energy source to supply the hydraulic system with hydraulic energy, the hydraulic energy source including at least one electrically driven hydraulic pump to supply the hydraulic system with hydraulic energy during a stopping phase of the internal combustion engine. To achieve a reduction in fuel consumption and CO2 emissions, provision is included to enable the electrically driven hydraulic pump to be switched on in addition to a mechanically driven hydraulic pump, as needed during an operating phase of the internal combustion engine.

Abstract: The invention relates to a hydraulic system for actuating a continuously variable belt-driven conical-pulley transmission having two conical pulleys encircled by an endless torque-transmitting means, each of which comprises two conical disks, one of which is axially movable depending on the pressure in an associated pressing chamber, and having a torque sensor which includes a torque sensing chamber that is connected to a hydraulic energy source and is linked with the pressing chambers.The invention is distinguished by the fact that the pressing chambers are connected via a first hydraulic resistance element to the torque sensing chamber, and via a second hydraulic resistance element to an additional pressure chamber, in which a lower pressure prevails than in the pressing chambers and/or the torque sensing chamber.

Abstract: A method for regulating or controlling the transmission ratio of an automatic power-branched transmission. Power is transmitted through a shaft driven by an engine, a variable speed drive, a gear transmission, a driven shaft, and at least two control clutches. The variable speed drive and the gear transmission are connected to each other in such a way that the regulating range of the variable speed drive is traversed in one direction within a first range of transmission ratios, and is traversed in the opposite direction within a second range of transmission ratios during traversing of the entire range of transmission ratios. The shifting strategies result in reduced wear of the endless belt device and allow for comfortable changing between the transmission ratio ranges.
