Differentials: Where the power, in most cars, makes its last stop before spinning the wheels.
The differential has three jobs:
To aim the engine power at the wheels
To act as the final gear reduction in the vehicle, slowing the
rotational speed of the transmission one final time before it hits the
wheels
To transmit the power to the wheels while allowing them to
rotate at different speeds.
Differentials are a variety of gearbox, almost always used in
one of two ways. In one of these, it receives one input and provides
two outputs; this is found in every automobile. In the other, less
commonly encountered, it combines two inputs to create an output that
is the sum (or difference) of the inputs.
In a truck and other vehicle, the differential allows each of the driving wheels to rotate at different speeds, while supplying equal torque
to both of them. In truck applications, the differential and its
housing are sometimes collectively called a "pumpkin or pig".
A vehicle's wheels rotate at different speeds, especially when turning
corners. The differential is designed to drive a pair of wheels with
equal force, while allowing them to rotate at different speeds.
