A Differential Gear in an Automobile is an Epicyclic Gear Train, used in automotive mechanics. The differential gear is a set of gears that allow power from the engine to be transmitted to a pair of driving wheels while dividing the force equally between them and allowing them to follow paths with different lengths, such as when turning a corner or driving over uneven terrain.

Differential Gear in an Automobile

Torque can be distributed asymmetrically between the front and rear axles using epicyclic differential and gearing.

  • The epicyclic differential, which connects the engine, motor generators, and drives wheels, is the driving force behind the Toyota Prius’s drive system (which has a second differential for splitting torque as usual).
  • It benefits from being comparatively small along the length of its axis.
  • Because the axes of the planet gears circle the common axis of the sun and the ring gears that they mesh with and roll between, epicyclic gears are even understood as planetary gears.
  • The yellow shaft carries the almost-hidden sun gear in the image.
  • The pink gear is the ring gear or annulus, and the blue gears are known as planet gears.


A Differential Gear in an Automobile is a?

An epicyclic gear train is a differential gear in an automobile. Epicyclic gears are also known as planetary gears. The wheels spin at the same pace on a straight road, but while a bend is being turned, the outside wheel has to go farther and, if unconstrained, will turn more quickly than the inner wheel.
