Abstract
A self-loading limited slip differential is disclosed including at least two concentric layers of pairs of generally semi-spherical shells for applying friction torque bias to the driven shafts via the side and planetary gears of the differential gearing assembly. The shells of one layer are rotatably mounted on the planetary pinion shafts, respectively, and the shells of the other layer are non-rotatably connected with the driven shafts, respectively, said shells being compressed together as the side and planetary pinion gears are displaced apart upon the application of torque to the differential casing. In an alternate embodiment, in order to increase the friction torque bias, an additional pair of concentric layers of shell pairs are mounted concentrically upon the first two shell layers.
