    [edit] Epicyclic differential


    Epicyclic gearing is used here to apportion torque asymmetrically. The input shaft is the green hollow one, the yellow is the low torque output, and the pink is the high torque output. The force applied in the yellow and the pink gears is the same, but since the arm of the pink one is 2x-3x bigger the torque will be 2x-3x higher.


    An epicyclic differential uses epicyclic gearing to split and apportion torque asymmetrically between the front and rear axles. An epicyclic differential is at the heart of the Toyota Prius automotive drive train, where it interconnects the engine, motor-generators, and the drive wheels (which have a second differential for splitting torque as usual). It has the advantage of being relatively compact along the length of its axis (that is, the sun gear shaft).

    Clipart illustrations of a simple machine, gears. Gears are used by connecting them to an axle, and using the interconnecting cogs to move other gears or parts of a system. Their mechanics are similar to the wheel and axle.
