Abstract:
1. An electric drive module for motor vehicles having different track width dimensions, the electric drive module comprising: an axle housing having an axial length dimension and defining a motor chamber and a gearbox chamber that are separated by a radial wall support; an electric motor assembly positioned within the motor chamber of the axle housing and including a cartridge housing containing a non-rotary stator and a rotor shaft rotatably supported by the cartridge housing; a reduction unit disposed in the gearbox chamber of the axle housing and having an input member driven by the rotor shaft and an output member driven at a reduced speed relative to the input member, the input member extending through a central aperture in the radial wall support of the axle housing into the motor chamber and being coupled for rotation with the rotor shaft; a differential assembly disposed within the gearbox chamber of the axle housing and having a differential input driven by the output member of the reduction unit, a first differential output driving a first output shaft, and a second differential output driving a second output shaft; a transfer assembly interconnecting the second differential output to the second output shaft, the transfer assembly including a transfer shaft connected to the second differential output and a coupling shaft selected from a plurality of coupling shafts each having a different axial dimension, the selected coupling shaft connecting the transfer shaft to the second output shaft; and a cover selected from a plurality of covers each having a different axial dimension, the selected cover being attached to the axle housing for enclosing an open end of the motor chamber, at least one of the selected coupling shaft and the second output shaft is rotatably supported by the selected cover, wherein the selected coupling shaft and the selected cover are selected in combination with the axle housing based on the vehicle track width dimension of the motor vehicle.
