2.3 OPERATING PRINCIPLE OF DIFFERENTIAL SYSTEM
In this case, both racks refer to the differential side
gears and the pinion refers to the differential pinion.
Also, the force that pulls up the pinion is the rotating
force of the ring gear.
However, if putting a weight only on one rack and lifting
the pinion, the pinion rises as it rotates as shown in the
fi gure (C). The rack with a weight keeps its position and
the other rack without a weight rises in the amount of
the height that the pinion moves and the pinion pushes
up the rack. Therefore, this rack rises in double amount
of the height that the pinion moves (2H).

However, if the wheels on one side are on the slip-
pery road, the load difference between both differential
side gears remarkably increases and the self-rotating
speed of differential pinion (3) considerably increases
too. Therefore, the side gear (5) with very low load ro-
tates with very high speed and the side gear (6) with
comparatively high load does not rotate at all.In other
words, it is not possible to escape the pit since the
wheel on ice with no friction rotates with high speed
and the wheel on road with friction does not rotate.

If the vehicle moves forward and the loads on the both
wheels are same, the differential pinion (3) idles in the
differential case (4) to run the differential side gear (5). In
this case, the rotating speed of the ring gear (1), differen-
tial case (4) and the both side gears (5) is same.
When cornering, the load applied to the both differen-
tial side gears (5) are different since the outer wheels
should rotate faster than the inner wheels. Therefore,
the differential pinion (3) rotates and idles simultaneous-
ly to operate the side gear with low load faster and the
side gear with high load slower for comfort cornering.

If two racks with same weight are set between the pin-
ion as shown in the fi gure (A) and the pinion is lifted
by pulling up the string attached to it as shown in the
fi gure (B), the pinion does not rotate and the pinion and
both racks are lifted in the same height (H).
