Inside the differential case the shafts carry the bevel sun gear with which bevel pinion mesh.
The bevel pinions are free to turn on the pin fixed in the differential case.
The differential provides an equal drive to each half shaft, although they may be rotating at different speeds.
It allows the outer wheel to rotate faster than inner wheel.
When vehicle is going straight there is no relative movement among the different gears.
In arrangement of differential the wheel is fixed to casing.
The inner ends of the half shafts pass through the boss of differential case in which they are free to rotate.

Inside the differential case the shafts carry the bevel sun gear with which
bevel pinion mesh.
The bevel pinions are free to turn on the pin fixed in the differential case.
The differential provides an equal drive to each half shaft, although they

It allows the outer wheel to rotate faster than inner wheel.
When vehicle is going straight there is no relative movement among the
different gears.
In arrangement of differential the wheel is fixed to casing.
The inner ends of the half shafts pass through the boss of differential case
in which they are free to rotate.
5. Vehicle Taking A Turn
when vehicle takes turn, the outer wheel travel on a longer radius
than inner wheel.
The outer wheel turns faster than inner wheel.
So there is a relative movement between two rear wheels.
6. Need Of Differential
If two rear wheels are rigidly fixed to rear axel the inner will slip, which
cause rapid tyre wear, steering difficulty and poor road holding.
Therefore there is a device , which divide the input torque of transmission
system between two rear axel is known as differential.
