Abstract
An electromotive actuator assembly for an electromechanical vehicle brake is disclosed having a transmission that comprises transmission shafts, cylindrical brake surface provided in the transmission and which encircles an axis of rotation, and a blocking element mounted eccentrically with respect to the axis of rotation. The blocking element is adjustable about a pivot axis by a drive unit and can be placed in contact with the cylindrical brake surface. The blocking element is arranged so as to become wedged together with the cylindrical brake surface with self-locking action in only one direction of rotation of the cylindrical brake surface about the axis of rotation (A). The disclosure also relates to a method for activating and deactivating a parking brake function.
