ABSTRACT:
Frictional effects at different gear mounting surfaces within a differential are varied to control bias ratio. The gearing arrangement includes side gears respectively coupled to axle ends and element gears which transfer and divide torque between the side gears. Coefficients of friction at end faces of the element gears are varied between different element gears to control overall bias ratio while minimizing the effect of changes in overall bias ratio on an inherent bias ratio imbalance between opposite directions of differentiation. Helical gear portions are formed at the ends of the element gears to better balance thrust forces acting on different element gears.
