Abstract: A suspension (14) for coupling a steer axle assembly (12) to a vehicle frame (10) is provided that provides lateral stability to the steer axle assembly, increased roll stability for the vehicle and a reduction in axle wind-up during brakingcall without interfering with vertical displacement of the axle assembly. The suspension includes leaf springs (44) disposed on opposite sides of the vehicle, each of which is coupled to the vehicle frame at first and second ends (64, 66) and to an axle beam (28) intermediate the first and second ends. The suspension also includes first and second arms (50, 150), each of which is pivotally coupled to the axle beam at a first end (70, 170) and to the vehicle frame at a second end (68, 168) proximate one of the ends of a corresponding leaf spring. The suspension may further include a torsion bar (52) extending between and coupled to the first and second arms.

Abstract: An apparatus for angularly positioning a shaker bed, including a discharge end, includes an air source providing pressurized air, an hydraulic tank in selective communication with the air source and containing a quantity of fluid, at least one bellow in selective fluid communication with the hydraulic tank, and a lift control assembly controlling communication of pressurized air between the air source and the hydraulic tank and controlling communication of fluid between the hydraulic tank and the at least one bellow.

Abstract: A steer axle for a vehicle and a method of making the same involves forming portions of a steer axle to have a three sided design. Spring seats that wrap around two of the three sides are secured to the steer axle. Plates are secured to the spring seats. The plates extend over the third surface of the steer axle. Angled spring pads are located over the plates.

Abstract: A suspension for coupling a steer axle assembly to a vehicle frame is provided that provides lateral stability to the steer axle assembly without the use of a track rod or stabilizer bar. The suspension includes a body that is coupled to the axle beam of the steer axle assembly. An arm extends from the body in the longitudinal direction of the vehicle and is coupled to the frame at one end. The arm is pivotable about an axis extending generally transversely to the frame rails of the vehicle frame. A male guide member is connected to the body and is received within a female guide member that is in turn disposed in an aperture defined by a bracket of the frame. The guide members are free to move within the bracket vertically or in the fore-aft direction, but are restricted from lateral movement.

Abstract: An accessory carrier assembly includes a reversible shank manufactured of a substantially square first portion and a substantially square second portion. The first portion is sized to engage a first hitch receiver and the second portion is sized to engage a second hitch receiver. To attach the accessory carrier to the reversible shank, the first segment is located in amounting assembly either with or without the bushings depending on which type of hitch receiver is available. The accessory carrier is pivotable by removal of a single pin to provide access to a rear of a vehicle. The single pin can be further located in a stop aperture to prevent overrotation of the carrier.
