Shift-by-wire shifting device having mechanical parking lock actuation

An actuation device for selecting gear settings of a shift-by-wire gear shifting transmission, the actuation device comprising:

• an actuation element that can move along at least one shifting path between at least one parking brake setting and a driving gear setting,
• a mechanical transference device to the transmission for the actuation of the parking brake, and
• a coupling device disposed between the actuation element and the transference device,
• wherein the coupling device is configured for the selective actuation of the transference device only for the engaging or disengaging of the parking brake setting on the actuation element,
• wherein the coupling device comprises a substantially prismatic bearing guide having a notch and a two part coupling carriage supported in a displaceable manner, separated into an actuation-side carriage part and a transference device-side carriage part,
• wherein the actuation-side carriage part and the transference device-side carriage part overlap one another in the coupled position at an overlap section in the guidance axial plane,
• wherein a locking element is disposed in the transference device-side carriage part in the overlapping section, at a right angle to the bearing guide, supported in a moveable manner, spaced apart from the bearing guide and the notch,
• wherein the locking element can move when the coupling carriage moves from a first relative position, in which both carriage parts are coupled to one another by an engagement of the locking element in both carriage parts, through moving over the notch, to a non-self-limiting second relative position, in which the engagement of the locking element in the actuation-side carriage part is released.
