ABSTRACT:
A differential (10) for use with dual wheel assemblies (12) includes pinion gears (34) commonly engaged with opposing pairs of bevel gears (36, 38) but at different drive ratios in order to effect differential drive between the dual wheel assemblies, as well as between the wheels in each assembly, so that all four wheels are positively driven independently.
