ABSTRACT:
A three-speed planetary transmission having a single ring gear and dual planetary gear sets meshing with the single ring gear. Gear changes are effected by coupling or alternately fixing a set of two sun gears which mesh with the two planetary gear sets. This transmission can provide a direct drive and two other speed ratios. Utilizing a single ring gear in combination with two planetary gear sets allows nesting of gear elements and economy of space for the transmission.
