摘要： A drive axle assembly includes first and second axleshafts connected to a pair of wheels and a drive mechanism operable to selectively couple a driven input shaft to one or both of the axleshafts. The drive mechanism includes a differential, a speed changing unit operably disposed between the differential assembly and one of the first and second axleshafts, and first and second mode clutches. The first mode clutch is operable to engage the speed changing unit for reducing the rotary speed of the second axleshaft relative to the rotary speed of the first axleshaft. The second mode clutch is operable to engage the speed changing unit for increasing the rotary speed of the second axleshaft relative to the rotary speed of the first axleshaft. A control system controls actuation of both mode clutches.
