ABSTRACT:
A variable ratio pulley system has a pair of pulleys mounted on input and output shafts, respectively, and interconnected by a drive belt. The pulleys are adjustably controlled in axial width to establish the drive ratio between the shafts. Each pulley has a load cam sensitive to the torque load being imposed on the respective shaft. The load cams are interconnected by a linkage and preload spring which establishes the minimum axial force operable on the pulleys. The linkage transmits forces between the pulleys thereby imposing a tension force on the belt established by the greater of the forces generated at the load cams. A drive ratio selector is connected to one side of the input pulley to add or subtract a force so that the axial forces on the input and output pulleys are properly balanced when the desired drive ratio is established. The output shaft of the pulley system is connected through a starting mechanism to a forward-reverse gear arrangement and then to a final drive and gear differential.
