Traveling Straight with the Same Road Resis-
tances to Left and Right Tires
As the differential pinion gear and the left and right
pinion gears rotate solidly, the drive forces of the left
and right tires are the same similarly to the TPD.
Traveling on Soft Roads (Different Road Resis-
tances to Left and Right Tires)
Drive force is transmitted to the case, pressure ring,
and spider through the ring gear. At this time, the
spider having the cam construction pushes the
pressure ring with the thrust (P). Clutch disc is
geared with the case through the pressure ring. Side
gears fitted to the clutch disc by spline rotate solidly
with the case, and the left and right gears rotate at
the same speed.
Like this, the left and right axle shafts fitted to the
side gears by spline tend to rotate solidly with the
case, and the differential movement restriction works.
In case the drive force provided for the skidding tire
is larger than the road resistance, part of the torque
of the skidding tire is added to the tire contacting the
road by the differential movement restriction (be-
cause of the same speed of the left and right tires),
and the tire contacting the road is provided with more
torque.
Until the difference of the resistances between the
left and right tires exceeds certain value (until the
clutch disc begins to slip), the left and right gears
solidly rotate at a constant speed. On such soft roads,
the drive force increases by 1.5 times the value for
the TPD if the LSD is provided.
