ABSTRACT:
In a powertrain, including a multiple-speed transmission, an axle shaft driven through differential mechanism, a two-speed axle mechanism includes an input shaft connected to the drive shaft, a multiple speed gear mechanism driveably connected to the differential mechanism. One form of the two-speed axle includes a planetary gearset, an overrunning brake, a brake band, and a friction clutch. Another form of the axle mechanism includes gears formed on the input shaft and output shaft, a planet gear wheel rotatably supported on a carrier, the gears of the wheel meshing with the gears on the shafts. A spring-applied clutch connects the output shaft to the carrier, and an hydraulically-actuated brake releases the clutch and holds the carrier against revolution on a casing.
