Patent ID: 6974400

Claim:
A transfer case comprising: an input shaft; first and second output shafts; a reduction unit having an input member driven by said input shaft and an output member driven at a reduced speed relative to said input member; a range clutch operable in a first mode to couple said first output shaft for rotation with said input shaft to establish a high-range drive connection therebetween, said range clutch is further operable in a second mode to couple said first output shaft for rotation with said output member to establish a low-range drive connection between said input shaft and said first output shaft; a transfer assembly; a bi-directional overrunning mode clutch operable in a first mode to permit relative rotation between said first output shaft and said transfer assembly in a first direction and prevent relative rotation therebetween in a second direction, said mode clutch further operable in a second mode to prevent relative rotation between said first output shaft and said transfer assembly in both directions; a disconnect clutch operable in a first mode to couple said second output shaft for rotation with said transfer assembly and in a second mode to release said second output shaft from coupled engagement with said transfer assembly; and a shift mechanism for shifting said range clutch between its first and second modes, said mode clutch between its first and second modes, and said disconnect clutch between its first and second modes.
