To provide an electrically-driven cargo vehicle which can optimize axle load distribution and improve maneuverability.SOLUTION: An electrically-driven cargo vehicle 1 comprises a pair of steering wheels 2 which is located below a cab 12, and a pair of driving wheels 3 which is located below a cargo box 3. Further, the electrically-driven cargo vehicle 1 includes: a rear axle part 5 comprising a pair of motor parts 5A, which are respectively mounted on the driving wheel 3 and give drive to the driving wheel 3, and a connection part which connects the motor parts 5A to each other; a pair of suspension parts 6 which respectively suspend the motor parts 5A on a pair of frames 4 which extend in a vehicle length direction; and a fitting parts 7 which are movably provided along the frames 4, and fit the suspension parts 6 to the frames 4. In this electrically-driven cargo vehicle 1, an inter-axel distance WB of the steering wheel 2 and the driving wheel 3 is changed according to a position of the fitting part 7 in the vehicle length direction.SELECTED DRAWING: Figure 1
【課題】車軸荷重配分を最適化できるとともに操縦性を向上させることができる電動貨物車両を提供する。【解決手段】電動貨物車両1は、キャブ12の下方に配置された一対の操舵輪2と、荷箱3の下方に配置された一対の駆動輪3とを備えている。また、電動貨物車両1は、駆動輪3にそれぞれ搭載されて駆動輪3に駆動力を付与する一対のモータ部5Aとモータ部5A同士を互いに連結する連結部とからなるリアアクスル部5と、車長方向に延びる一対のフレーム4にモータ部5Aをそれぞれ懸架する一対の懸架部6と、フレーム4に沿って可動に設けられ、懸架部6をフレーム4にそれぞれ取り付ける取付部7とを含んでいる。電動貨物車両1では、取付部7の車長方向における位置に応じて、操舵輪2と駆動輪3との車軸間距離WBが変更される。【選択図】図1
