Abstract
A multiwheel landing gear assembly includes a forward set of wheels which are in tandem with a middle set of wheels which in turn are in tandem with a rear set of wheels. The forward set of wheels are connected to a main support strut of the landing gear by a levered arrangement. The middle and rear set of wheels are connected together by a truck beam which in turn is connected to the main support strut by a radius rod. When the middle and rear wheels are subject to an upward force such as when the aircraft is landing, the radius rod limits movement of the wheels in a generally upward direction along a path having a radius which is equal to the length of the radius rod. Movement of the middle and rear wheels along the path in the upward direction is resisted by a shock absorber. In this manner, the vertical loads are reacted in a lengthwise direction along the radius rod and shock absorber.
