Abstract
A vehicle driveline component with an actuator and a rotary coupling. The actuator has an actuator housing, a motor, a transmission, a first cam, a second cam, and a first biasing spring. The motor is coupled to the actuator housing and includes a motor output member. The transmission has a transmission input member, which is driven by the motor output member, and a transmission output member. The first cam is housed in the actuator housing and is coupled to the transmission output member for rotation therewith. The first cam has a first set of cam features that are disposed about a first annular surface. The second cam has a cam body, which is received in the first cam, and a second set of cam features that are disposed about a second annular surface. The second set of cam features abut the first set of cam features. Rotation of the first cam relative to the second cam into a first position orients the first set of cam features onto the second set of cam features so as to position the second cam in an extended position relative to the first cam. Rotation of the first cam relative to the second cam into a second position orients the first set of cam features onto the second set of cam features so as to position the second cam in a retracted position relative to the first cam. The first biasing spring is disposed between the first and second cams and biases the second cam toward the retracted position. The rotary coupling has a first coupling member, a second coupling member and a second biasing spring. The first coupling member is rotatably and axially slidably received in the second cam. The first coupling member is axially movable between a first coupling position, in which the first coupling member is decoupled from the second coupling member, and a second coupling position in which the first coupling member is coupled to the second coupling member to permit the transmission of rotary power through the rotary coupling. The second biasing spring is disposed between the first coupling member and the second cam.
