Abstract
A continuously variable transmission. The transmission includes a plurality of power adjusters, such as spherical balls, frictionally interposed between a driving and a driven member. The driving and the driven member are each rotatably disposed over a main shaft. The spherical balls are configured to rotate about a modifiable axis and thereby provide a continuously variable shifting capability by adjusting the ratio between the angular velocity of the driving member in relation to the driven member. The system includes automatic and manual shifting gearing for adjusting the speed of the transmission. The system also includes a support a support member which is rotatably disposed over the main shaft and frictionally engaged to each of the spherical balls.
