ABSTRACT:
An electrical actuation for an automatic transmission, preferably for selection actuation in automobiles in which a four-bar linkage transmission and a worm gear unit are arranged between the electric drive and the transmission. Shifting can be carried out with a low-output drive, particularly in the parked shifting position “P”, also when very large forces are required such as those occurring when the vehicle is parked on a hill.
