Abstract

An actuating device for selecting fixed gear ratios of a gear shifting transmission. The actuating device comprises a shift lever movable between at least three gear positions, and a lockout mechanism for limiting the range of motion of the shift lever. The lockout mechanism comprises a locking assembly including at least one locking chamber disposed in at least one locking roller, and the shift lever includes at least one locking cam. The locking cam can be inserted into the locking chamber to limit the range of motion of the shift lever. It is thus possible to implement actuating and locking tasks in the field of shift-by-wire transmissions, in a simple way and with minimal construction space requirements. The actuating device produces minimal noise and has short shifting times, and makes it shift-by-wire-controlled H shift patterns possible.
