Abstract: A suspension for a vehicle includes a pair of opposing upper and lower control arms that longitudinally locate an axle along the frame. The upper and lower control arms include first ends pivotably mounted to the ends of the axle at upper pivotable axle joints and a second lower pivotable axle joints, respectively. The upper and lower control arms include second ends that are pivotably mounted to frame hanger brackets at upper and lower pivotable hanger joints, respectively. The frame hanger bracket are laterally interposed between an upper and lower hanger joint so that an upper pivotable hanger joint is on one side of each frame hanger and a lower pivotable hanger joint is on an opposite side of the each frame hanger.

Abstract: A self-adjusting, self-damping air spring having a first air spring disposed between a cab and a frame of a vehicle and a second air spring in fluid communication with the first air spring. The second air spring positioned relative to the first to provide an opposition force in response to a change in height of the first air spring. This change in height corresponds to a change in displacement between the cab and the frame. The opposition force provided by the second air spring acting to dampen the changes in displacement.

Abstract: A mounting arrangement for a vertically oriented exhaust system component includes a base member mountable to a vehicle frame with a plurality of upstanding rods fixed to the base member. At least one clamping band is interconnected with the plurality of rods and can be clamped onto an exhaust component. The arrangement is advantageous for heavy components such as SCR catalyst bodies and diesel particulate filters.

Abstract: An apparatus for affecting airflow in a gap between a lead vehicle and a connected trailing vehicle, includes a guide vane having a leading edge, a trailing edge, a gap side surface, and an outward facing surface, and a support apparatus mountable on a vehicle for supporting the guide vane in a vertical orientation relative to the vehicle with a space between the vehicle and the guide vane gap side surface and with at least a portion of the vane extending beyond an end of the vehicle. The flow guide divides an air flow at the trailing edge of a vehicle to avoid the creation of turbulence in the air flow as it encounters the gap between the vehicle and the trailing vehicle.

Abstract: A tow assembly for a truck for high capacity loads provides independent load paths interconnected to a tow eye for bearing a towing load. According to one embodiment, the assembly includes a mounting interface having a front face and oppositely located side faces and defining an interior space, a first outer member extending from one side face of the mounting box, a second outer member extending from an opposite side face of the mounting box, an inner member disposed and extending through the first outer member, the interface, and the second outer member, and, a tow eye mounted to the front face of the interface and structurally interconnected to the inner bar. Towing loads are transmitted to the mounting interface and distributed and shared by the inner member and first and second tube structure.
