ABSTRACT:
A continuously variable transmission with synchronous shift includes an input, an output, a fixed-ratio drive mechanism and a variator in driven relationship with the input, a planetary gear assembly having a sun gear, a ring gear, a carrier, and a plurality of planet gears, a first clutch for engaging the variator selectively with the sun and ring gears, a second clutch for engaging the mechanism selectively with the carrier and sun gear and for disengaging the mechanism therefrom, and a third clutch for engaging the ring gear and carrier selectively with the output. This relationship provides the transmission with a plurality of drive ranges and the capability of shifting from any range to any other range at a synchronous shift point established when the variator ratio is equal to the ratio of the mechanism.
