摘要:
An actuating device for selection on shift steps of a gear changing transmission. The actuating device comprises a flexible gear selection device (1) with at least two drive step positions, a park lock position and an additional park lock-actuating device (4) for activation of the park lock. When the gear selector device (1) moves out of the park lock position, the gear selector device (1) becomes disengaged while movement of the gear selector device (1) from one of the drive step positions into the park lock position, or beyond the previous park lock position, does not engage the park lock. Engagement of the park lock is only achieved by actuating the additional park lock-actuating device (4). This improves the safety and provides intuitive shifting between the different drive step positions without the need to view the gear selector device. The unintended engagement of the park lock is precluded.
