Patent ID: 8720659

Claim:
An overrunning coupling and control assembly comprising: first and second coupling members supported for rotation relative to one another about a common rotational axis, the first coupling member having a coupling first face oriented to face axially in a first direction along the rotational axis and the second coupling member having a coupling second face opposed to the first face and oriented to face axially in a second direction along the rotational axis, the second coupling member having a third face spaced from the second face and oriented to face axially in the first direction; the second face having a set of pockets spaced about the rotational axis, each pocket of the set having a strut received thereby; the first face having a set of locking formations that are engaged by the struts upon projecting outwardly from the set of pockets to prevent relative rotation of the first and second coupling members with respect to each other in at least one direction about the axis; the third face having a set of passages spaced about the rotational axis and in communication with their respective pockets; a support member; and an electromechanical actuator subassembly including: an electromagnetically inductive coil to create a magnetic flux when the coil is energized, wherein one of the support member and the second coupling member is an armature member of the subassembly, the armature member being mounted for controlled shifting movement along the rotational axis relative to the first coupling member between a first position which corresponds to a first mode of the assembly and a second position which corresponds to a second mode of the assembly; a set of actuators supported by the support member, each passage of the set of passages having an actuator received thereby to actuate its respective strut within its respective pocket so that its respective strut moves into contact with the locking formations to couple the first and second coupling members for rotation with each other in at least one direction about the rotational axis in one of the positions of the armature member; and at least one biasing member exerting a biasing force on the armature member along the rotational axis wherein a control force is applied to the armature member when the coil is energized to cause the armature member to move from its first position to its second position along the rotational axis against the biasing force of the at least one biasing member and wherein in the absence of the control force the at least one biasing member moves the armature member from the second position back to the first position along the rotational axis.
