Abstract
A clutch hub is selectively held against rotation by a brake and selectively coupled to an input shaft by a clutch. The clutch pack for the brake is splined to the outside of the clutch hub while the clutch pack for the clutch is splined to the inside. To reduce axial length, the clutch packs are packaged radially outside of a gear set, increasing the diameter of the clutch hub. When the clutch hub is subjected to high rotational speeds, high centrifugal stresses result. These stresses are reduced by openings in the spline teeth and in the recesses between the spline teeth. Fluid flow to the outer clutch pack is controlled by openings in a clutch housing.
