OPERATION (TORQUE TRANSMISSION) WHEN THE SPEEDS OF THE LEFT AND RIGHT WHEELS ARE
DIFFERENT
When one wheel is in contact with a concrete road surface (which has high coefficient of fridtio?) and the
other wheel is in contact with a muddy or other slippery road surface (which has low coefficient of friction),
the differential operation will cause the speed of the wheel in contact with the slippery surface to be faster
than the speed of the drive gear, lowering the maximum drive force. If this occurs, the limited slip function will
control the differential operation and increase the driving force,
The transmission of torque through the limited slip device in this event is as follows:
When the differential case is turned by the drive gear and the drive pinion, the pressure rings which are
interlocked with the differential case will turn at the same speed. Also, the difference in the road surface
resistances will cause differential operation and the left and right side gears will revolve at speeds different
from that of the differential case. Because of the friction produced between the clutch plates in mesh with
both the side gear and differential case, one of the pressure rings increases its rotating speed, whereas the
other reduce5 its rotating speed. The pressure rings press the tapered portion of the pinion shaft with which
they are in contact, and thereby receive reaction force in both the lateral direction and the direction of rotation.
The reaction force in the lateral direction causes the clutch plates to mesh, increasing the frictional and the
drive force.
