International Classification:

B60G 1126

US Classification:

280707

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.

International Classification:

B62D 6110

US Classification:

180 2402

Abstract:

An undercarriage (12) includes a primary frame (22) and a plurality of secondary frames (26) which in turn carry wheel members (28). The secondary frames (26) are urged to pivot away from the primary frame (12) by spring mechanisms (38). An undercarriage (112) includes a primary frame (122) and a plurality of secondary frames (126) which in turn carry wheel members (128). Pivotal movement of the endmost secondary frames (126e) is controlled by spring/shock absorber assemblies (134). Pivotal movement of the center secondary frame (126c) is controlled by a spring/shock absorber/cylinder assembly (136). Spring/shock absorber/hydraulic cylinder assemblies (250) may be used to control the positioning of all of the wheels of an undercarriage (422, 452, etc. ).

Appl. No.:

6/695405

Inventors:

Norman D. Oswald - Duncanville TX
Harry S. Mankey - Dallas TX

International Classification:

B62D 1102

US Classification:

180 648

Abstract:

An undercarriage (250) is provided for supporting and propelling a mechanism (252). The undercarriage (250) includes a main frame (256) and side frames (258) pivotally mounted at the fore and aft ends of the main frame and on either side thereof. Two axles (270) are rotatably supported on each side frame (258) and on opposite sides of the pivotal axis of the side frame. An inner wheel (266) and an outer wheel (268) are mounted on the axles (270). A double-acting fluid cylinder (284) is interconnected between the main frame (256) and each side frame (258). Pressurized fluid may be provided to the chambers within the fluid cylinders (284) to lock the side frames in a position so that the inner wheels (266) extend below a plane defined by the bottom surfaces of the outer wheels (268) to facilitate skid steering. The fluid cylinders may also be activated to lock the side frames in a position so that the outer wheels (268) are in contact with the surface (272) to lengthen the effective wheelbase of the undercarriage (250). The fluid cylinders (284) may also be interconnected for flow of pressurized fluid so that the side frames (258) form a walking beam arrangement and the load on the inner and outer wheels (266,268) are maintained substantially equivalent.

Appl. No.:

6/027754

Inventors:

Norman D. Oswald - Duncanville TX
Harry S. Mankey - Dallas TX

Assignee:

Standard Manufacturing Company, Incorporated - Dallas TX

International Classification:

B62D 1102

US Classification:

180 648

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. Also included in the undercarriage is a drive assembly having a motor connected to a transmission mounted inboard or outboard of the frame.

Assignee:

Standard Manufacturing Company - Dallas TX

International Classification:

B60P 300

US Classification:

414458

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. The hydraulic cylinders are arranged in sets, with each cylinder of each set having sufficient capacity to support the entire load regardless of the condition of the other cylinder.
