Abstract
A differential features larger amplitude in gear ratio fluctuation and higher torque bias ratio. When one of the driving wheel slips, the period of the gear ratio fluctuation between the pinion and side gears involves at least two pitches, thus each period of the gear ratio fluctuation involves a group of teeth, and the number of teeth involved in each group are corresponding to the number of pitches involved in each period. Each pinion has an odd number of groups of teeth, and the group number in side gears is a multiple of the number of pinions. The differential is particularly suitable for off-road vehicles, tippers and wheeled civil engineering machinery.
