ABSTRACT:
Methods are disclosed for controlling a variable-speed transmission utilizing a pulley structure including first and second pulley members coupled for free rotation together about a shaft. The second pulley member can be axially movable relative to the first pulley member, and can include a pulley contact surface disposed generally opposite to the first pulley member. A coupling member is provided for communicating with the shaft to rotatably drive the shaft. The coupling member includes a coupling member contact surface disposed for selective frictional engagement by the pulley contact surface. Torque can be selectively coupled and decoupled to a transmission, as well as vary a speed of the transmission.
