Abstract

The present invention proposes a power train and the operation thereof, suitable for automated actuation of a transmission shiftable between a plurality of gears with a torque transmitting system being actuated automatically at least during a gear change, at least one actuating element operable by at least one drive unit and at least one actuatable shift element being disposed at the transmission side. The invention provides a power train in which a driving connection is disposed between at least one actuatable shift element associated with the transmission and an actuator having at least one drive unit, and at least one presettable elastic means is provided in the power transmitting path of the driving connection between the drive unit and the at least one shift element. Further, at least one additional presettable elastic element can be disposed in the power transmitting path between the at least one actuating element and the at least one shift element on the transmission side.
