摘要
A two-speed full-time transfer case includes an input shaft, first and second output shafts, a planetary gearset, an interaxle differential, and first and second clutch mechanisms. The planetary gearset includes a sun gear integral with the input shaft, an annulus gear, and pinion gears rotatably mounted on a carrier and which are meshed with the sun and annulus gears. The interaxle differential has an input driven by the carrier, a first output driving the first output shaft and a second output driving a transfer mechanism coupled to the second output shaft. The first clutch mechanism is a fluid-actuated bi-directional overrunning clutch operable for selectively braking the annulus gear. The second clutch mechanism is a fluid-released bi-directional overrunning clutch for selectively releasing the input shaft from coupled engagement with the carrier.
