Patent ID: 7874398

Claim:
A motor vehicle and drive system thereof, comprising: a body having a body front end and an oppositely disposed body rear end; a first axle shaft; a second axle shaft, wherein said first and second axle shafts are independently suspended with respect to said body; a differential drivingly connected to said first and second axle shafts; and a rigid torque arm having a torque arm forward end and an oppositely disposed torque arm rearward end, said torque arm forward end being rigidly connected to said differential and said torque arm rearward end being pivotally connected to said body at a location closer to said body rear end than is said differential, wherein the torque arm rearward end is retained at a fixed spatial distance from the body at the connection; wherein said torque arm positively couples vibrations as between said first and second axle shafts by a non-linear coupling of vertical and torsional motions directly to the body so as to thereby decay powerhop oscillations of the first and second axle shafts.
