<p><P>PROBLEM TO BE SOLVED: To provide a device for controlling and/or regulating hydraulically operated shift element capable of operating a transmission with high efficiency. <P>SOLUTION: The shift element 2 is configured with a piston-cylinder unit 3 that can be acted upon by a hydraulic operating pressure p and can be arranged in an installation space that is connected to an oil sump of the gearing mechanism device. In addition, the device 1 is provided with an electric motor 5 that can be actuated by a control and/or regulator unit, and which is provided with a drive-transformer device 6 that has a functional connection to the electric motor 5, by way of which the rotational drive of the electric motor 5 can be transformed into the hydraulic operating pressure p for the shift element 2. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
