Abstract: An adverse terrain vehicle is provided which includes a system for controlling a number of vehicular functions. The vehicle includes at least two variable displacement hydraulic motors, each for driving at least one wheel member on one side of the vehicle independently of the wheel members on the opposing side thereof. At least two variable displacement hydraulic pumps are mounted on the vehicle for supplying pressurized hydraulic fluid to the hydraulic motor on one side of the vehicle independently of the hydraulic motor on the opposing side thereof. The hydraulic pumps are driven by an engine. A sensor detects a decrease in the power output of the vehicle below that selected by the vehicle operator. Overload protection circuitry is responsive to the overload sensor and adjusts the displacement of the hydraulic motors and pumps to increase the power output capacity of the vehicle. Braking control circuitry coordinates with braking of the vehicle steering to effect turning of the vehicle while braking.

Abstract: The present invention is a system for powering a trailer. The system includes a trailer having a tongue for connecting the trailer to a towing vehicle. The trailer is supported by at least one wheel mounted on each of opposing sides of the trailer frame. Mounted on the trailer is a motor for driving the trailer wheels. Power is supplied to the motor from the towing vehicle.

Abstract: An auxiliary lift adapter (10) comprises spaced, parallel top load beams (40), bottom load beams (30) positioned beneath the top load beams, and scissors mechanisms (50) for raising and lowering the top load beams (40). Each scissors mechanism (50) comprises an exterior arm (52) pivotally connected to its bottom load beam (30) and slidably connected to its top load beam (40), an interior arm (54) pivotally connected to its top load beam (40) and slidably connected to its bottom load beam (30), and a pin (56) pivotally interconnecting the midpoints of the arms. Hydraulic cylinders (76) are provided for actuating the scissors mechanisms (50) and include safety locking valves for preventing operation of the cylinders in the event of loss of hydraulic pressure.

Abstract: An aerial weapons handling trailer includes a frame comprising longitudinally extending beams and a cross beam interconnecting the front ends of the longitudinally extending beams. The frame is supported on wheels which are pivotable between positions wherein the trailer is movable longitudinally and positioned wherein the trailer is movable laterally. The wheels include drive motors for positioning the trailer. A plurality of lift arms are pivotally supported on the longitudinally extending beams of the frame and in turn support lift beams. The lift arms include inwardly offset portions, and the lift beams are separated by a distance not greater than the width of a weapons package that is lifted and positioned by the trailer. The lift arms are actuated by hydraulic cylinders which are provided with load lock valves to prevent inadvertent lowering of the load carried by the lift beams.

Abstract: A detachable undercarriage for use on adverse terrain vehicles comprises an elongate hollow load-bearing frame having three or four axles rotatably supported thereon. Sprockets are mounted on at least two of the axles, and chains are constrained around the sprockets to drivingly interconnect the axles. The center axle in the three axle embodiment and the center two axles in the four axle embodiment are positioned below a plane extending through the axes of rotation of the outermost two axles to facilitate skid steering of vehicles incorporating the undercarriage. Alternatively, all the axles can be aligned with larger wheels mounted on the center axle in the three axle embodiment or the center two axles in the four axle embodiment to facilitate skid steering. In certain applications of the nonaligned axle embodiments structure is provided for selectively aligning all the axles to increase vehicle stability.
