Abstract: A non-torque reactive air suspension exhibiting excellent roll stability characteristics is shown to include frame hangers mounted to frame rails extending longitudinally on opposite sides of a vehicle. Longitudinally extending beams are connected to the frame hangers at one end and extend parallel to the frame rails. At their other ends, the beams are joined by a crossbrace extending laterally across the vehicle centerline. In a central portion thereof, the beams have an axle pivot bore to which an axle clamp assembly is connected, the axle clamp assembly clamping a drive axle housing for the vehicle. The axle pivot bore is generally aligned with the drive axle. A control rod assembly is connected to suspension or frame components. Together with the beams, the control rod assembly forms a parallelogram configuration wherein the beams form the lower linkages of that configuration and the control rods included within the control rod assembly form the upper linkages of that configuration.

Abstract: A suspension system component for use in association with a leaf spring eye wrap of a leaf spring is shown to include a generally rigid planar base portion and a generally rigid scarf gap cover portion extending from the base portion in a direction generally normal to the base portion. The scarf gap cover portion includes first and second cover portion portions extending in different planes and adjoined at a seam. The component further includes a generally rigid first stop portion formed as a peg-like structure extending from the base portion in the same direction as the scarf gap cover portion. The component also includes a generally rigid second stop portion formed as a curved engagement surface extending from the base portion in that same direction.
