In
this example we can now see a complete differential and crownwheel. The bevel pinions (sun gears) are mounted
within the differential cage. Power is transmitted from the crownwheel
through the differential cage which in turn rotates the bevel pinions and half shafts as a complete fixed unit when
driving in a straight line.
As
the vehicle travels round a bend the bevel pinions are free to spin on their
axes to allow for the individual half shafts to decrease and increase in speed.
As the half shaft driving the inner wheel reduces in speed the outer wheel half
shaft will increase in speed as the distance required to travel round the bend
will be higher.
The Crownwheel will allways rotate at an average of the two half
shaft speeds
