Abstract:
A transfer case, comprising:an input shaft;a first output shaft;a second output shaft;an interaxle differential having a first output member fixed to said first output shaft, a second output member fixed to said second output shaft, and an input member driving said first and second output members while permitting speed differentiation therebetween;a transfer clutch operable in a non-actuated condition to permit unrestricted relative rotation between said first and second output shafts, and said transfer clutch is operable in a fully-actuated condition to inhibit relative rotation between said first and second output shafts;a shift sleeve supported for rotation with said input shaft and movement between first and second positions, said shift sleeve is operable in said first position to couple said input shaft to said input member of said interaxle differential for establishing a full-time four-wheel drive mode, and said shift sleeve is operable in said second position to couple said input shaft to said input member and said first output member of said interaxle differential for establishing a locked four-wheel drive mode; andan actuator for controlling movement of said shift sleeve between said first and second positions and for controlling the actuated condition of said transfer clutch when said shift sleeve is in said first position.
