An actuator with an indexing guide, first and second indexing rings, an actuator output, a spring and a motor. The indexing guide has a first cam. The first indexing ring is slidably mounted to the indexing guide and includes a second cam. The second indexing ring is slidably and rotatably disposed on the indexing guide and has spline teeth, which engage the first cam, and a third cam that engages the second cam. The spring exerts a force onto the second indexing ring that drives the second indexing ring toward the first indexing ring. The motor is configured to reciprocate the first indexing ring so that cooperation between the second and third cams and between the spline teeth and the first cam causes axial and rotational movement of the second indexing ring about an actuation axis. |
