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.
A differential for motor vehicles and the like comprising, an input drive shaft, a pair of coaxially spaced drive gears simultaneously driven by the input drive shaft in a same direction at a same speed of rotation about a common axis of rotation, a driven gear driven by the pair of drive gears for transmission of power from the input drive shaft, two coaxial opposed sun gears having an axis of rotation concentric with an axis of rotation of the driven gear, two planetary gears disposed between the sun gears for differential driving thereof during turns of the vehicle to the right and to the left with the sun gears for driving the sun gears, each planetary gear having a separate axis of rotation carried by the driven gear and each disposed therein and radially symetrically relative to the axis of rotation of the sun gears, and each sun gear having a respective power output shaft connected thereto for rotation therewith.
A differential for motor vehicles and the like comprising, an input drive shaft, a pair of coaxially spaced drive gears simultaneously driven by the input shaft in a same direction at a same speed of rotation about a common axis of rotation, a driven gear driven peripherally by the pair of drive gears for transmission of power from the input drive shaft, two coaxial opposed bevel sun gears having an axis of rotation concentric with an axis of rotation of the driven gear, two planetary gears disposed between the sun gears for differential driving thereof during turns of the vehicle to the right and to the left each meshing with the sun gears for driving the sun gears, each planetary gear having a separate axis of rotation carried by the driven gear disposed therein radially and symmetrically relative to the axis of rotation of the sun gears, and each sun gear having a respective power output shaft connected thereto for rotation therewith.
