ELECTROMECHANICAL SYSTEM FOR CONTROLLING THE OPERATING MODE OF A SELECTABLE CLUTCH ASSEMBLY AND AN OVERRUNNING COUPLING AND ELECTROMECHANICAL CONTROL ASSEMBLY USING THE SYSTEM

摘要

An electromechanical system for controlling the operating mode of a selectable clutch assembly and an overrunning coupling and electromechanical control assembly using the system are provided. A bi-directional, electrically-powered actuator assembly including an output member is coupled to a control member for selective, small-displacement, control member angular rotation about a first axis between different angular positions which correspond to different operating modes of the clutch assembly. The actuator assembly includes a rotary output shaft, a threaded screw shaft coupled to the output shaft to rotate about a second axis substantially perpendicular to the first axis and a cam having a contour surface. The cam is threaded onto the screw shaft to move linearly along the second axis upon rotary movement of the screw shaft. The output member rides on the contour surface of the cam so that the output member rotates with the control member about the first axis.
