ABSTRACT:
A planetary transmission (10) is disclosed including a front section (48) having a rotating housing (52) and a planetary gear set (18) with a ring gear (62), a sun gear (64) and a planet carrier (66). Advantageously, the ring gear (62) is the input and the rotating housing (52) is the output, and the sun gear (64) is continually held stationary. A first clutch assembly (32) connects the planet carrier (66) to the rotating housing (52) and provides underdrive and a second clutch assembly (34) connects the ring gear to the rotating housing (52) and provides direct drive. The front section (48) is operatively connected to a rear section (50) for multi-speed use especially adaptable to an agricultural vehicle.
