Rear Differential Operation - Honda S2000 Service Manual

Operation
. Straight-road driving
The differential carriel and gears rotate together as a unit when both wheels rotate at the same speed. Turning eflort
from the final driven gears are directlv transmitted to both wheels.
. When rounding a curve
When the vehicle rounds a curve, the differential allows the outer wheel to rotate a little faster than the Inner wheel.
When this takes place, the short and long pinion gears rotate, and walk around the side gears in the directions
shown lf, for example, the right shaft is rotated in a counterclockwise d irection with the different jal carrierhetd
stationary, the force is transmitted through the right side gear, short pinion gears and long pinion gears to the left
side gear, causing the left shaftto rotate in a clockwise direction. This allows the outerwheel to tua ao.".,."a

When limiting differential action
The limited slip differential acts to limit the differential action when either wheel slips on ice or snow or on
rurns.
This is done by using the friction created between each gear and differential carrier:
(1) The pinions are forced against the differential carrier by the force as they
are rotated and repelled outward.
(2) The ends of the pinion gears are held firmly against the differential carrier
due to the side thrust from the

With the pinion gears locked, the torque applied to the slipping wheel is reduced and the torque delivered to
the
