Abstract From the Canadian patent

A limited slip differential (10) with a hydrostatic pump (96). A pair of pressure plates splined to the carrier define a pair of opposed ramps. They are engaged by differential pinions carried by a pinion shaft. The pinions engage each of the two side gears. A friction clutch assembly is situated adjacent each side gear. The pressure plates transfer an axial component of the thrust force created on the ramp surfaces as torque is transmitted through the pinions and through each side gear of each of two axle shafts. Each friction clutch assembly includes friction disks carried by the side gears and by the carrier so that a bias torque is established as one axle shaft overspeeds the …

Why it's free to use

  • Filed July 6, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 6, 2019.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 6, 2021.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
