Limited-Slip Operation - Mazda 2006 MX-5 Service Highlights

Limited-slip operation

• If the differential encounters a condition requiring limited-slip control such as wheel spin, thrust force acts on
the side gears due to the reaction force from the meshing of the pinion and side gears. This thrust force
presses the side gears against the taper ring, generating friction between the side gear cone and the taper ring
and reducing the torque of the slipping wheel. The reduced torque is transmitted without change to the wheel
with higher traction, and the limited slip differential function is provided. The torque transmitted to the wheel
with higher traction is proportionate to the input torque of the ring gear.
