ABSTRACT:
A continuously variable transmission includes at least one transmitter having two graduated surfaces mounted to provide frictional engagement with a driving cylinder and a driven cylinder. A shifter having two graduated surfaces is axially mounted within the housing. The transmitter is not mounted on a shaft, but is urged into engagement with the driving cylinder and the driven cylinder by two elongated followers. Each follower includes a first end and an opposing second end. Axial movement of the shifter provides simultaneous and opposing movement of the first and second followers to impart pivotal movement of the axis of rotation of the transmitter.
