Abstract: A suspension system for a vehicle includes an extendable and retractable actuator disposed at each side of a frame of the vehicle and pivotally attached at one end to a vehicle bracket and at the other end to a suspension bracket. The suspension bracket includes an actuator portion, an axle portion and a suspension arm, with the actuator portion and the suspension arm pivotable relative to an axis of the axle portion. When the actuator is extended or retracted, the actuator portion pivots about the axis of the axle portion and imparts pivotal movement of a suspension arm about the axis to adjust a height of the frame of the vehicle. The actuator includes an elastomeric element disposed between an outer end of a slide rod and an outer end of a ram rod, with the slide rod movable to absorb sudden movements of the frame or wheel.

Abstract: A utility trailer with a movable bed floor includes a trailer frame supported by a plurality of wheel assemblies. A bed panel is coupled with the trailer frame and defines an upper support surface. A live-bed flexible member spans the length and width of the upper support surface. A load chain is coupled between forward and rearward ends of the live-bed flexible member and span the length of the bed panel below the bed panel. A drive system is supported by the trailer frame. The drive system has a sprocket engaged with the load chain and is operable to drive the live-bed flexible member in forward and rearward directions over the upper support surface for loading and unloading items from the utility trailer.
