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 the axleshafts. The drive mechanism includes a
differential assembly, a planetary gear assembly operably disposed
between the differential assembly and the first axleshaft and first and
second mode clutches. The first mode clutch is operable with the
planetary gear assembly to increase the rotary speed of the first
axleshaft which, in turn, causes a corresponding decrease in the rotary
speed of the second axleshaft. The second mode clutch is operable with
the planetary gear assembly to decrease the rotary speed of the first
axleshaft so as to cause an increase in the rotary speed of the second
axleshaft. A control system controls actuation of both mode clutches.
