Abstract:
A non-torque reactive air suspension exhibiting excellent roll stability characteristics is shown to include frame hangers (26) mounted to frame rails (20) extending longitudinally on opposite sides of a vehicle; wherein, the suspension includes longitudinally extending beams (28) are connected to the frame hangers (26) at one end and extend parallel to the frame rails (20), other ends of the beams (28) are joined by a crossbrace (32) extending laterally across the vehicle centerline; wherein each of the beams (28) having an axle pivot bore (36) to which an axle clamp assembly (38) is connected, the axle clamp assembly (38) clamping a drive axle housing (22) for the vehicle; wherein the axle pivot bore (36) is generally aligned with the drive axle (22); a control rod assembly (40) is connected to suspension; the control rod assembly (40) and the beams (28) formed a parallelogram configuration.
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.
