Abstract
A clutch module which includes a first rotating member including at least one strut actuation module and a second engaged member including cam surfaces thereon for engagement by said strut actuation module. The strut actuation module includes a frame with a strut pivotally movable with respect to the frame. The strut includes an engagement end and a base end including a first side and a second side thereof. A pin or post portion extends from the frame and has an insulated bobbin with an energizable coil surrounding the bobbin. A U-shaped member including a pair of actuation legs is attached to the pin member and forms a magnetic gap between the base end of the strut and peripheral ends of the legs, such that when the coil is energized the peripheral ends of the legs are polarized in a first polarity and the frame and the strut are polarized with an opposite polarity thereby biasing the strut toward the peripheral ends and pivoting the actuation end into engagement with a cam surface of the engagement member.
