ABSTRACT:
A fully geared continuously variable transmission controls output ratios of differentiating gear sets by using a control gear set that is controlled as to rotation speed by a variable speed drive. The ratio gear sets can be bevel gear differentiating clusters or planetary gear sets. As disclosed, the transmission may have two sets of ratio control gears driving separate output shafts that are coupled to rotatable worms engaged with a worm gear to control differentiation between the output shafts which are used as drives for two wheel or four wheel drive vehicles at selected engine idle rpm the variable speed drive rotates the control gears at a selected speed and directs rpm, that holds the output shafts at 0 rpm. As engine rpm is increased to selected cruising final drive ratio the variable speed drive rpm is decreased proportionately to zero to change the output drive ratio continuously as a function of a selected parameter.
