Abstract
A two speed shift mechanism for a belt drive that includes a rotatable shaft with a first pulley, and a tube concentric with the shaft and rotatable therearound. The tube includes a shift hub supporting a second pulley in axially spaced relation to the first pulley for concentric rotation about the shift hub. The mechanism further includes a collar mounted around the shift hub for rotation with the fit hub and for axial movement between a position adjacent the first pulley and a position adjacent the second pulley. In a first position, the collar and the first pulley include elements engageable for connecting the collar to the first pulley for rotation of the collar, the shift hub and the tube. In a second position, the collar and the second pulley include elements engageable for connecting the collar to the second pulley for rotation of the collar, the shift hub, and the tube.
