Patent ID: 7850555

Claim:
An apparatus for controlling a variable-speed transmission, the transmission comprising a coupler for alternately engaging and disengaging power between the transmission and a motor, and an adjustable torque transfer mechanism interconnecting the transmission and the motor for varying a speed of the transmission, the apparatus comprising: (a) an actuator cam rotatable through a first phase and a subsequent second phase and comprising a variator surface rotatable therewith; (b) a cam follower in communication with the coupler and the actuator cam, wherein rotation of the actuator cam through the first phase causes movement of the cam follower, which causes movement of the coupler between a disengaged position and an engaged position; and (c) a speed adjustment cam comprising a speed adjustment cam surface, the speed adjustment cam surface comprising a flat and an incline, wherein the variator surface is movable along the flat in response to rotation of the actuator cam through the first phase without enabling adjustment of the torque transfer mechanism, and the variator surface is movable along the incline in response to rotation of the actuator cam through the second phase for enabling adjustment of the torque transfer mechanism.
