Publication number: 20120272769Abstract: 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.Type: ApplicationFiled: April 21, 2012Publication date: November 1, 2012Applicant: Schaeffler Technologies AG & Co.

Patent number: 8196401Abstract: A hydraulic system for controlling a belt-driven conical-pulley transmission. A pump draws a working medium from a working medium tank or through a cooler return valve from a cooler return line. The cooler return valve is a minimum pressure valve that holds closed a connection between the cooler return line and a pump inlet line through the cooler return valve, as long as the pressure in the cooler return line remains below a specified minimum pressure. The cooler return valve also opens the connection between the cooler return line and the pump inlet line through the cooler return valve as soon as the specified minimum pressure in the cooler return line is exceeded.Type: GrantFiled: November 29, 2008Date of Patent: June 12, 2012Assignee: Schaeffler Technologies AG & Co.
