Abstract:
A clutch pulley for selectively engaging a belt of a first device and a shaft of a second device, comprising:a sheave member including a sheave belt surface to engaging the belt, and including a sheave clutch surface; an electro-magnetic coil located near said sheave member and to selectively creating an electro-magnetic flux; a flex plate including a flex inner section concentrically coupled over the shaft, a flex outer section adapted to selectively move between two axial positions relative to said flex inner section based upon the presence of said electro-magnetic flux, and a flex spoke section connecting said flex inner section and said flex outer section; a support member connected to said shaft and said flex plate, said support member adapted to carry the electro-magnetic flux; and a ring member connected to said flex outer section and including a ring clutch surface selectively engaging said sheave clutch surface based upon the axial position of said flex outer section.
