Abstract
Official abstract text for this publication.
A differential with one or more friction and thrust washer sets so that axially generated thrust forces can be used in certain situations to affect a torque bias ratio of the differential.
First claim
Opening claim text (preview).
What is claimed is: 1. A differential comprising: a differential case; first and second side gears received in the differential case; a plurality of first pinions received in the differential case and meshingly engaged with the first side gear; and a plurality of second pinions received in the differential case and meshingly engaged with the second side gear, each of the plurality of second pinions meshingly engaging an associated one of the first pinions; wherein the firs…
