Abstract
An actuator assembly comprises a rotatably drivable drive gear; a locking ring which is rotatably mounted in a stationary housing and is drivingly connected to the drive gear, wherein the locking ring is rotatable from a first rotational position into a second rotational position against a rotation stop; wherein at least one friction face pairing is provided in the power path between the drive gear and the locking ring, via which a torque can be transmitted to the locking ring by frictional forces; a first ramp ring drivable by the drive gear and a second ramp ring, which are axially supported against each other and are configured to convert rotary movement into axial movement; wherein the first ramp ring, after the locking ring has reached the rotary stop, can be further rotatably driven by the drive gear.
