2.2 PRINCIPLE OF DIFFERENTIAL SYSTEM
If two racks with same weight are set between the pin-
ion as shown in the figure (A) and the pinion is lifted by
pulling up the string attached to it as shown in the fig-
ure (B), the pinion does not rotate and the pinion and
both racks are lifted in the same height (H).
T46W603A
However, if putting a weight only on one rack and lifting
the pinion, the pinion rises as it rotates as shown in
the figure (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).
T46W602A
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.
If the tractor moves forward and the loads on the both
wheels are same, the differential pinion (3) idles with
the differential case (4) to run the differential side gear
(5). In this case, the rotating speed of the ring gear (1),
differential case (4) and the both side gears (5) is same.
When cornering, the load applied to the both differen-
tial side gears are different since the outer wheels
should rotate faster than the inner wheels. Therefore,
the differential pinion rotates and idles simultaneously
to operate the side gear with low load faster and the
side gear with high load slower for comfort cornering.
