A limited slip differential assembly comprising a differential case and two side gears rotatively supported within the differential case. Each of the side gears provided with a pre-loaded
clutch pack mounted on a hub portion of the side gear.
In one embodiment, a lock ring is permanently pressed on the hub portion of the side gear adjacent a collar and the clutch pack for retaining the clutch pack in a predetermined pre-loaded condition. In a second embodiment, an adjustment collar is threaded into the side
gear and a thrust washer having a selected thickness maintains the pre-loaded condition.
In both embodiment, a side gear / clutch pack assembly may be pre-assembled as a
pre-loaded self-contained module before the various components of the differential assembly
are assemble in the differential case.
The two clutch packs on side gear hubs. The plates are keyed to the case, whereas the discs
are splined to the side gear hub. Since these plates are alternatively stacked, any rotation of
differential gears causes the frictional surfaces of the plates to turn against each other.
Clutch Pack.
housing two bevel side gears co-axial withe case. Each of the side gear is inter-meshing with
bevel planet gears which are supported in the case on the axis perpendicular the axis of the
side gears.
Between the differential case and the side gears are interposed the respective clutch
assemblies, usually in the form of clutch packs comprising alternatively stacked clutch plates
and discs, and Belleville spring, to provided the limited slip action.
