PROBLEM TO BE SOLVED: To provide a carrier assembly for an automatic transmission capable of reducing backlash during operation and including an inexpensive one-way brake capable of being easily manufactured by using reinforced metal. SOLUTION: This carrier assembly for a planetary gearset of the transmission includes a pinion carrier, a one-way brake having a rocker ring 22 integral with the pinion carrier and having multiple pockets mutually spaced about an axis and located on an outer radial surface of the carrier. A cam ring includes multiple notches angularly spaced about the axis and facing the rocker ring 22. A rocker 86, located in each pocket, pivots about a pivot center to engage the cam ring, and a spring member 44 urges each rocker 86 to pivot toward engagement with the cam ring. A hydraulically actuated friction brake secured to the carrier alternately holds the carrier against rotation relative to a housing and permits the carrier to rotate. COPYRIGHT: (C)2006,JPO&NCIPI
