<p>A clutch pulley for selectively engaging a belt of a first device and a shaft of a second device, including a sheave member, an electro-magnetic coil, a flex plate, and a ring member. The sheave member includes a sheave belt surface adapted to engage the belt and a sheave clutch surface. The electro-magnetic coil is adapted to selectively create an electro-magnetic flux. The flex plate includes a flex inner section concentrically coupled over the shaft, a flex outer section adapted to selectively move between two axial positions relative to the flex inner section based upon the presence of the electro-magnetic flux, and a flex spoke section connecting the flex inner section and the flex outer section. The ring member is connected to the flex outer section and includes a ring clutch surface adapted to selectively engage the sheave clutch surface based upon the axial position of the flex outer section. <IMAGE></p> |
