Abstract
A planetary gear assembly is disclosed having a sun gear fixed for rotation with an input, a ring gear, and a planet carrier fixed for rotation with an output and which has a plurality of planet gears rotatably supported thereon that mesh with the sun gear and the ring gear. To establish the high and low-range drive connections between the input and the output, a first range sleeve is supported for rotation with the input and is movable between a neutral position and an engaged position whereat the input is coupled to the planet carrier. In addition, a second range sleeve is supported for rotation with the ring gear and is movable between a neutral position and an engaged position whereat the ring gear is coupled to a stationary brake plate. Accordingly, the high-range drive connection between the input and the output is established when the first range sleeve is in its engaged position and the second range sleeve is in its neutral position. Moreover, the low-range drive connection between the input and the output is established when the first range sleeve is in its neutral position and the second range sleeve is in its engaged position. Finally, a neutral mode is established where…
