Abstract
An automotive differential (10) is modified to provide better control over torque transfers between a housing (12) and a pair of output shafts (16 and 18), as well as torque transfers between the output shafts (16 and 18). Friction modifiers (66 and 86) are located at various end faces of side gears (30 and 32) coupled to the output shafts (16 and 18) for varying bias ratios in opposite directions of torque transfer between output shafts (16 and 18) independently of directions of torque transfers between the housing (12) and the output shafts (16 and 18).
