Thrust forces (34 and 36 88 and 90, or 144 and, 146) generated within the differential are opposed by at least one pair of surfaces (38 and 40, 96, 98 and 104 106, or 152, 154, and 156, 158) having different frictional characteristics. One of the surfaces (38, 96 and 98, or 152 and 154) opposes a portion of the thrust forces, and the other surface (40 104 and 106, or 156, and 158) opposes a remaining portion of the thrust forces.

Why it's free to use
- Filed April 28, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 28, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 28, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
