ABSTRACT:
An independently suspended, driven axle shaft set in which the axle shafts are asymmetric with respect to each other, wherein the asymmetry provides mitigation of powerhop. The asymmetric axle shafts are asymmetrically selected such that the relative torsional stiffness therebetween is different by a ratio substantially between about 1.4 to 1 and about 2.0 to 1. The asymmetry may be provided by any known modality that alters torsional stiffness and is compliant with operational load demands of the axle shafts, as for example the axle shafts having the same length, but differing cross-sectional diameters; or by the axle shafts having the same cross-sectional diameters, but differing lengths; or a combination thereof.
