Actuator assembly for clutch assembly for vehicle power train

Actuator assembly for a clutch arrangement in a driveline of a motor vehicle, comprising:

• a rotatably drivable drive gear;
• a locking ring mounted in a stationary housing so as to be rotatable about an axis of rotation and drivingly connected to the drive gear via a power path;
• wherein the locking ring is rotatable by the drive gear from a first rotational position into a second rotational position against a rotation stop;
• and
• wherein at least one friction face pairing is provided in the power path between the drive gear and the locking ring, via which torque is transmittable to the locking ring by means of frictional forces;
• a first ramp ring that is rotatably drivable by the drive gear;
• and
• a second ramp ring;
• wherein the first ramp ring and the second ramp ring, which are arranged in the power path between the drive gear and the locking ring, are axially supported against each other and are configured to convert a relative rotary movement into an axial movement;
• wherein the first ramp ring, after the locking ring has reached the rotation stop, is further rotatably drivable by the drive gear.
