Abstract

An actuating device for selecting gear steps in a gearshift transmission. The actuating device comprises a selector lever that can be moved between at least two drive-setting positions and a locking mechanism for restricting the movement range of the lever and locking certain positions or for locking the selector lever. The locking mechanism comprises a locking recess connected to the selector lever and a blocking cam that can be rotated by an actuator. The cam engages in the locking recess. Complex locking tasks are possible with the simplified actuating device. In addition, the range of movement of the selector lever can be freely positioned largely variably and its width can be changed. Furthermore, the selector lever of the actuating device is movable by the actuator or locked in a desired position.
