Abstract
A pair of tension cables are positioned around cams attached to the lower control arms of a vehicle suspension. Each tension cable includes a tension damper responsive to tension in the tension cables. Each tension damper includes a cylinder containing a fluid and a piston including at least one orifice attached to a rod. The piston divides the cylinder into a first and second compartment. The rod in connected to the tension cable. When the tension cable pulls on one end of the rod, the piston is pulled towards the tension cable. The fluid creates resistance in the tension damper as the fluid moves through the orifice from one compartment to the other compartment, damping vehicle roll. Control of the tension dampers can be passive, semi-active, or active.
