ABSTRACT:
An automatic transmission for an automotive vehicle includes two variator of the traction drive type, each variator including an input disc, an output disc, and rollers driveably engaged with the discs and adapted to vary continuously the ratio of the speeds of the output disc and input disc, the output disc of the first variator producing a predetermined speed in relation to the speed of an input shaft and driveably connected to a disc of the second variator. A planetary gear unit includes a carrier, a sun gear connected to mutually connected discs, a ring gear connected to the output disc of the second variator, and a set of planet pinions meshing with the respective sun gear and ring gear. Angular variation of the rollers causes the second variator to drive the ring gear at a variable speed relative to input shaft speed and the carrier to rotate in accordance with the speeds of the sun gear and ring gear.
