Abstract

Abstract A carrier for an automatic transmission of a motor vehicle is provided. The carrier comprises a hub, an annular face plate, a plurality of posts, and a plurality of planetary gears. The hub includes a collar having internal teeth adapted to mesh with an input or an output shaft, and a disc attached to the collar. The posts are generally cylindrical, and extend between the hub and the face plate substantially within the respective perimeters of the hub and the face plate. The planetary gears are disposed in a gear pocket between the hub and the face plate, with each planetary gear being mounted on an associated pinion shaft and adapted to mesh with both a sun gear and a ring gear.
