Abstract
A transmission assembly includes a stationary housing and a first section having a coupling member. The first section further includes a first planetary gear assembly, a second planetary gear assembly, and a third planetary gear assembly operatively disposed in the stationary housing. Each of the planetary gear assemblies includes a ring gear, at least one planet carrier having at least one planet gear, and a sun gear. The sun gears of at least the first and second planetary gear assemblies are operatively connected to the coupling member. The first section also includes an input member operatively connected to the third planetary gear assembly to drive the first section. A first stationary clutch operatively connects the coupling member to the stationary housing. A second stationary clutch operatively connects at least one of the planet carrier and the ring gear of the first planetary gear assembly to the stationary housing.
