ABSTRACT:
A differential for motor vehicles and the like effectively providing smooth power transmission from an input drive shaft driving two gears fixed axially spaced thereon driving with pin-like teeth, on side faces thereof, a driven gear having peripheral teeth oval in cross section and coaxial with two output bevel sun gears disposed opposed and having respective power output shafts for differential driving of the motor vehicle left and right wheels during turns. The output sun gears are disposed concentric with the driven gear with a common axis of rotation normal to the axis of rotation of the drive gears. The sun gears are driven differentially during vehicle turns by two bevel planetary gears each having as axis of rotation fixed in the driven gear and extending radially toward the axis of rotation common with the sun gears and symmetrical to the axis of rotation thereof.
