The Ravigneaux Gear Train is a double planetary gear set. The planet gears share the same carrier. Th RGT is smaller and lighter than a simpler combination of the planetary gears. They can be used to realize 6-speed, 8-speed, and 10-speed transmission systems.
The planet gears from the first stage internally mesh with the sun gear and externally mesh with the ring gear. The planet gears in the second stage meshes with the first planet gears and the small sun gear.
