Rotating clutch pack assembly

摘要

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.
