摘要

The control gear has an activated piston-cylinder-unit (7). A pressure, pressure restoration and pressure release is adjusted in the piston driving the piston-cylinder-unit in a working chamber (A) of the hydraulic control cylinder. The working chamber of the hydraulic control cylinder is connected consecutively and simultaneously with mechanical actuators of a coupling (19,23) as well as gear actuator (32-35) of the control gear by hydraulic pipe and intermediary controlled valves. The piston is driven by an electric motor (6). An independent claim is also included for a method for operating a control gear.
