Abstract

An actuator and clutch assembly for a power transmission device includes a first and second clutch members arranged to selectively define a connected state of the clutch when the second clutch member is drivingly engaged with the first clutch member and a disconnected state of the clutch when the second clutch member is not drivingly engaged with the first clutch member. An electric motor drives an input member driven for rotation about an axis, and an output member is driven axially relative to the input member when the input member rotates, wherein the second clutch member moves axially with the output member. A spring provides a force on the output member that biases the output member in a direction in which the second clutch member is moved toward the first clutch member. The spring is radially and axially overlapped by the input member and the output member.
