ABSTRACT:
Mechanism for minimizing the tendency of a vehicle to overturn or roll during high speed turns on unbanked road or rail surfaces. The mechanism includes a heavy (high mass) piston arranged in a fluid cylinder extending transversely across the vehicle undersurface; auxiliary pistons are arranged at opposite ends of the main cylinder. Centrifugal force generated during a turning maneuver forces the main piston to move outwardly along the turning radius, the main piston thereby displacing hydraulic fluid that acts on the auxiliary pistons in a pressurizing or depressurizing fashion. The auxiliary piston at the outer circumference of the turn forces that side of the vehicle up relative to the ground surface; the auxiliary piston at the inner circumference of the turn forces that side of the vehicle down relative to the ground surface. The vehicle sprung mass thereby assumes a banked attitude that enables it to more effectively resist vehicle overturning forces.
