Abstract: 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.

Abstract: A suspension for and a method for suspending a vehicle having a body is provided. The suspension includes a first wheel assembly suspension and a second wheel assembly suspension. The first wheel assembly suspension extends between a first wheel assembly and the body. The first wheel assembly suspension includes an instant center. The second wheel assembly suspension extends between a second wheel assembly and the body. The second wheel assembly suspension includes an instant center. The first wheel assembly and the second wheel assembly are aligned so that a vertical centerline of each wheel assembly lies within a vertical plane that extends therebetween. In one embodiment, the instant center of each wheel assembly suspension is located within the vertical plane, below a roll center located within the vertical plane.

Abstract: A zero roll suspension system for a vehicle is proposed which includes a vehicle frame and a wheel assembly having an axis of rotation about which a wheel of the wheel assembly rotates. The suspension system substantially eliminates rolling of the vehicle frame and includes a first weight bearing member and a second weight bearing member, each having a first end and a second end. One of the first and second ends of each of the first and second weight bearing members are rotatably connected to a portion of the wheel assembly and the other of the first and second ends of each of the first and second weight bearing members are rotatably connected to the vehicle frame. The first and second weight bearing members are oriented in substantially parallel planes between the wheel assembly and the vehicle frame and cross one another in superposition along a crossing axis, substantially prohibiting the vehicle frame from rolling during a cornering operation of the vehicle.
