Abstract:
A transfer case comprising:an input shaft; first and second output shafts; a reduction unit driven by said input shaft and having a reduction output member driven at a reduced speed relative to said input shaft; a differential assembly having a differential input member, a first differential output member driving said first output shaft, a second differential output member, and a gearset permitting speed differentiation between said first and second output shafts; a first clutch operable in a first state to couple said differential input member to said input shaft and in a second state to couple said differential input member to said reduction output member; a second clutch operable in a first state to establish a first drive ratio between said differential input member and said first differential output member and in a second state to establish a second drive ratio therebetween; and a third clutch operable in a first state to couple said second output shaft to said first and second differential output members and in a second state to couple said second output shaft to said first differential output member.
