Differentials part 2

الجهاز الفرقى الجزء 2
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
1. Thrust washer
2. Planet gear
3. Planet gear shaft
4. Sun gear (side gear)
5. Thrust washer / shim
6. Differential cage
