Abstract
A planetary transmission (10) is disclosed for a vehicle or the like which has input and output members (100,16), and first and second planetary gear sets (26,28). The second planetary gear set (28) has a second sun gear (154) connected to the input member (100), a second ring gear (156) connected to a first sun gear (138) of the first planetary gear set (26), and a second planet carrier (160) connected to the output member (16). A coupling device (162) is used for connecting the first and second planet carriers (144,160) for joint rotation which is at least in part disposed radially outwardly of the second planetary gear set (28). Brake assemblies (38,46) are provided for selectively holding the second and first ring gears (156,142) stationary and providing forward and reverse modes of operation respectively.
