LIMITED SLIP DIFFERENTIAL
NOBBBAA
A limited slip differential is an anti-slipping device which functions as a differential during cornering to allow
the outer wheel to turn at a faster speed than the inner wheel. In the event that one wheel begins spinning
(driving on slippery road surfaces, one wheel leaves the road surface. etc.), it automatically functions to
prevent such spinning.
CONSTRUCTION AND FUNCTION
With a conventional differential, in the event that one wheel of the vehicle is on ice, mud, or some other
slippery surface, the wheel will spin and the drive force of the vehicle will be greatly reduced. If this happens,
the speeds of the differential case and of the side gear (axle shaft) are different because of differential
operation. The limited slip function acts to limit this differential operation. The construction is shown in the
illustration. The multi-plate clutches engage with the differential case and with each of the side gears. If
spinning causes a difference in component speeds, the frictional force between the clutch plates will cause
the speed of the side gear to become closer to that of the differential case, and thus the limited slip function
will control the spinning. In addition, the purpose of the pressure rings inside the differential case is to the
driving force to the pinion gear, and the reason for the separation is to provide an increase in the clutch plate
pressing force through the leverage of the pinion shaft.
