Abstract
A planetary transmission (10) is disclosed including a front section (42/160) having a rotating housing (46/176) and a planetary gear set (20/162) with a ring gear (66/168), a sun gear (68/170) and a planet carrier (70/172). Advantageously, the rotating housing (46/176) serves as the input and one of the planet carrier (70) and the ring gear (168) serves as the output. The sun gear (68/170) is continually held stationary, a first clutch assembly (30/164) selectively connects the rotating housing (46/176) to the ring gear (66/168), and a second clutch assembly (32/166) selectively connects the rotating housing (46/176) to the planet carrier (70/172). The front section (42/160) of the transmission (10) is operatively connected to a rear section (44) for multi-speed use particularly adaptable to a truck or earthmoving vehicle.
