PCT No. PCT/US87/01330 Sec. 371 Date Jun. 4, 1987 Sec. 102(e) Date Jun. 4, 1987 PCT Filed Jun. 4, 1987 PCT Pub. No. WO88/09886 PCT Pub. Date Dec. 15, 1988.A continuously variable differential (10) uses a continuously variable transmission (50) that is rotated by drive torque and controlled to vary the speed ratio between its outputs. These, which previously transmitted power through the transmission, are connected with a pair of drive shafts such as opposed drive axles (17 and 18) that rotate with the transmission under drive power. Differentiation between the shafts transmits through the transmission via variable speed ratios that control the moment arms, mechanical advantages, and torque bias ratios. This arrangement allows the torque to be distributed according to sensed vehicle conditions. It can apply more torque to a wheel retaining traction when its opposite wheel slips, and it can apply a larger portion of the torque to wheels bearing more weight or to a faster rotating wheel on an outside of a curve.
