Abstract

See full text

An independently suspended, driven axle shaft set in which the axle shafts are driven by a differential which is rigidly connected to the body of the motor vehicle by a rearward torque arm, whereby powerhop is mitigated thereby. Where the axle shafts are torsionally asymmetric with respect to each other, the differential is a limited slip differential and the relative torsional stiffness therebetween is different by a ratio substantially between about 1.4 to 1 and about 2.0 to 1, wherein powerhop is mitigated synergistically by both the rearward torque arm and the asymmetric axle shafts.
