A drive axle assembly includes first and second axleshafts and a drive
mechanism coupling 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, a brake and first and second mode clutches. The first clutch
is operable with the brake and 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 clutch is operable with the brakes and 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.
