Zero roll suspension system

The present invention relates generally to a suspension system for vehicles, and more particularly to a suspension system for controlling the lateral roll of a vehicle during cornering and additionally for controlling fore-aft movement, or pitch, commonly described as vehicle rise and squat, caused by the inertia of the vehicle during acceleration and deceleration. A zero roll suspension system for a vehicle that includes a vehicle frame and a wheel assembly has an axis of rotation. The present system preferably includes first and second crossing members, each of which has a first end and a second end. One of the first and second ends of each of the first and second crossing members is adapted to be mated to a portion of the wheel assembly. The other of the first and second ends of each of the first and second crossing members is adapted to be mated to the vehicle frame. The first and second crossing members are oriented so as to cross one another in superposition along a crossing axis while each crossing a longitudinal centerline of the vehicle.
