Shift-by-wire actuating device having mechanical parking brake actuation

摘要

The structure and the installation of the mechanical transmission linkage to the parking lock is simplified in that the mechanical transmission linkage allows a smooth operation and serves also as an actuating devices having more than one shift gate without requiring complex modifications. An actuating device for selecting gear steps of a shift-by-wire gearshift transmission with a base housing, a selection lever, mechanical transmission for actuating a parking lock, and with a coupling system with a coupling element between the selection lever and the transmission. The transmission is selectively actuated by the coupling element only during selection and/or deselection of the parking lock position on the selection lever. The actuating device has includes the coupling element with a first end which is linearly guided in a slot and a second end which is in certain sections pivotally guided in a slot. The two ends of the coupling element are each supported on both sides in associated slotted tracks in the base housing. The coupling element is indirectly coupled to the selection lever.
