MULTI-MODE CONTINUOUSLY VARIABLE TRANSMISSION WITH SELECTABLE TRANSFER GEARS
Abstract:
A multi-mode continuously variable transmission (CVT) for a motor vehicle includes a transmission input member, a transmission output member, a planetary gear set, a forward clutch, a brake, and a continuously variable unit having a first pulley, a second pulley, and an endless member wrapped around the first pulley and the second pulley. A first transfer gear set is connected to the transmission output member. A second transfer gear set is connected to the transmission output member. A dual clutch assembly is provided having a first clutch and a second clutch, wherein the first clutch selectively connects the second pulley to the first transfer gear set and the second clutch selectively connects the second pulley to the second transfer gear set. The dual clutch assembly provides two modes or ranges of continuously variable speed ratios between the transmission input member and the transmission output member.
