Free-floating planetary transmission with reversible output

摘要

A planetary transmission having free-floating compound planetary gear elements in which two of the planet gears of each planetary element mesh with a pair of gears co-axial with the transmission axis. The transmission also includes selectively operable clutch and brake means for connecting either of said pair of coaxial gears to the transmission output while the other of said pair of gears is connected to a fixed structure thereby providing the transmission with a reversible output.
