    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.

    Abstract: A transmission having a rotating clutch pack assembly is provided, the rotating clutch pack having an interconnecting member, a plurality of friction discs, a rotating member, a first and a second axial bearing, and a biasing member. The interconnecting member is connected for common rotation with a member of the planetary gear set. The rotating member is connected to the second set of friction discs for common rotation. The first axial bearing is disposed between the clutch piston and the plurality of friction discs and the second axial bearing is disposed between the plurality of friction discs and the transmission housing. The biasing member is disposed between the interconnecting member and the rotating member. A clutch piston selectively applies an axial force through the first axial bearing, the plurality of friction discs, and the second axial bearing to the transmission housing.
