Abstract:
1. A clutch assembly comprising: a clutch module including a first clutch member and a second clutch member arranged to permit relative rotation therebetween, said second clutch member having a plurality of ratchet-type first cam surfaces formed therein; and a strut actuation module including a frame mounted to said first clutch member, a strut pivotally moveable with respect to said frame and including an engagement end and a base end, a post member extending from said frame, an insulated bobbin mounted on said post member with an energizeable coil surrounding said bobbin, and a U-shaped member including a pair of actuation legs attached to said post member and forming a magnetic gap between said base end of said strut and peripheral ends of said actuation legs, such that when said coil is energized said peripheral ends of said actuation legs are polarized in a first polarity and said frame and said strut are polarized with an opposite polarity thereby biasing said strut toward said peripheral ends of said actuation legs and causing said engagement end of said strut to pivot into engagement with one of said first cam surfaces formed on said second clutch member.
