Abstract
The invention relates to a setting device for an adjustable gearing mechanism, in particular, for selecting a parking position in an automatic transmission. The inventive setting device comprises a mechanical setting element, an intermediate gearing mechanism for transferring the setting motion of the setting element to a control element of the adjustable gearing mechanism. A mechanical energy store, which can be replenished once again by the setting element, is provided for driving the intermediate mechanism when the setting element malfunctions.

A setting device for an adjustable gearing mechanism for selecting a parking position in an automatic transmission, comprising
- a setting element having a setting motion;
- an intermediate gearing mechanism for transferring the setting motion of the setting element to a control element of the adjustable gearing mechanism, the intermediate gearing mechanism comprising a movably mounted carrier linked to the setting element via a spindle, a carriage mounted in a linearly movable manner in parallel with the carrier and linked to the control element, and a controllable locking element to link the carriage to the carrier or separate it from the carrier;
- and
- a mechanical energy store for driving the carriage in the event of a failure of the setting element.
