ABSTRACT:
In a vehicle comprising sprung and unsprung masses, rollout of the sprung mass on its support springs and away from the unsprung mass due to centrifugal force on the sprung mass in turns is eliminated and free independent movement of the wheels is permitted by pivoting the sprung mass at two locations on an axis passing through the center of gravity of the sprung mass and lying in a plane parallel to the centrifugal force vector. The centrifugal force acting on the center of gravity of the sprung mass has no direct overturning moment around this pivot axis. The resulting centrifugal force component on each axis pivot is transmitted to the wheels and ground without producing any rollout deflections of the main vehicle support springs. In particular the pivot force at the critical rear suspension is conveyed directly to ground by means of two independent torque tubes and torque arms. The anti-roll torsion bar is eliminated and softer body support springs may be used for improved isolation of road shocks and vibrations from the sprung mass.
