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
axleshafts, a transfer clutch and first and second brakes. The first
brake is operable with the transfer clutch 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 brake is operable with the transfer clutch 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 brakes and the
transfer clutch.
