Electric drive axle system

Abstract:

An electric drive axle system has an integral electric machine. An axle system includes a pair of output shafts and a motor with a rotor shaft disposed in line with the output shafts. A gearset is coupled between the rotor shaft and one output shaft. Another gearset is coupled between the rotor shaft and the other output shaft. Each gearset has a sun gear meshing with a set of planet gears supported on a carrier. The rotor shaft is fixed to the sun gears and the output shafts are fixed to the carriers. A clutch may alternately prevent or allow rotation of ring gears of the gearsets.
