A wheel drive assembly and suspension for a vehicle wheel includes a
spindle, a wheel drive shaft that rotates relative to the spindle about
an axis of rotation, and an electric motor that has a motor output shaft
for driving the wheel drive shaft. A motor housing encloses a speed
reducing planetary gear set that is driven by the motor output shaft. The
motor output shaft and the wheel drive shaft are co-axial. A suspension
arm extends in a direction transverse to the axis of rotation. The
suspension arm includes a pivot end attached to a vehicle structure and
an attachment end that is rigidly attached to the motor housing such that
the electric motor is a structural part of the suspension.
