Abstract
A power splitting differential transmission unit by which input power is transmitted in a controlled manner to one or both of two differential output shafts at continuously variable output/input speed ratios. The unit includes an integrated pair of continuously variable transmission units by which the output/input speed ratio for each output shaft may be adjusted synchronously for driving both output shafts at equal speeds within the speed ratio range of the unit, for varying the output/input speed ratio for each output shaft independently or for simultaneously increasing the output/input speed ratio with respect to one output shaft while decreasing the same ratio with respect to the other of the two shafts.
