PROBLEM TO BE SOLVED: To solve the problems of causing a floating-up phenomenon of a front wheel when climbing since a front-rear axle load balance is undesirable, and of causing an inner wheel difference between inside front-rear wheels when curving for fixing a rear wheel shaft, since the most part of gross weight of including a live load is shared by a rear wheel driving shaft, from the relationship between a strength limit and the wheel number, since this form is complicated in a structure of a front wheel steering shaft, though a tire type transport vehicle having a loading space is many in the form of arranging a steering mechanism on a front wheel shaft and a driving shaft on a rear wheel shaft.SOLUTION: The occurrence of an inner wheel difference is eliminated by attaining averaging of a sharing load of front-rear axle loads being the problem by arranging a turning wheel shaft steering mechanism A in a rear wheel or by being set in the same orbit by turning front-rear lower base plates at the same angle in the opposite direction by operating a steering cylinder 8 when executing steering, by arranging a turning wheel shaft steering mechanism A or B of incorporating a structurally simple and thrust-load-resistance-large turning seat bearing 5 into a front wheel of a tire type transport vehicle.SELECTED DRAWING: Figure 3
【課題】荷台を有するタイヤ式運搬車両は前輪軸に操舵機構と後輪軸に駆動軸を配置する形態が多いが、この形態は前輪操舵軸の構造が複雑で強度的な限界と輪数の関係から、積載荷重を含めた総重量の大半を後輪駆動軸に分担させている、そのため前後の軸重のバランスが悪く登坂時に前輪の浮き上がり現象等が発生する、又後輪軸を固定するためカーブを切った場合、内側の前後輪の間で内輪差か発生する課題が有った。【解決手段】タイヤ式運搬車両の前輪に、構造が単純でスラスト耐荷重が大きい旋回座ベアリング5を組み込んだ旋回車輪軸操舵機構AかBを配置し、後輪に旋回車輪軸操舵機構Aを配置することで課題である前後の軸重の分担荷重の平均化を達成し、又ステアリングを切った場合にステアリングシリンダー8が作動し、前後の下部ベース板を反対方向に同角で旋回させ同一軌道とすることで内輪差の発生を解消する。【選択図】図3
