Abstract

A control device for semiautomatic gearshifting mechanisms of motor vehicles has a selector shaft of a gearshifting mechanism and at least one rotatable shifting element acting on the selector shaft so as to rotate and axially move the selector shaft for selecting a gutter and shifting a gear. A switching valve actuates the at least one shifting element for rotating the selector shaft and for axially moving the selector shaft. The shifting element is a shift drum with at least one control curve. The control curve is a groove in the mantle of the shifting element. The control device provides a simplified hydraulic control of the switching valves and has a simplified configuration.
