The present invention relates to an amphibious ship. The amphibious ship includes: a hull; a foldable front wheel installed on a ship′s bottom around a bow of the hull; and a pair of foldable rear wheels installed on both sides of the ship′s bottom around a stern of the hull. The amphibious ship comprises: a front wheel shaft in which the front wheel is rotatably assembled; a shaft bracket fixed to both sides of the front wheel shaft; a moving piece assembling groove formed in one side of a lower part of the shaft bracket; a moving piece having one end hinged and fixed to the moving piece assembling groove; a lower load having a lower end hinged and fixed to the other end of the moving piece; a buffer spring inserted into the lower load; an upper load into which an upper end of the lower load is inserted; a fixture fixed to a boundary between the lower load and the upper load, and fixing the buffer spring while preventing the lower load and the upper load from being separated from each other; and a bracket base to which an upper end of the upper load and an upper end of the shaft bracket are respectively hinged and fixed, and which can be folded by a front wheel folding cylinder. According to the present invention, wheels of the amphibious ship can be suspended independently of a hydraulic circuit such that a structure can be simplified, thereby reducing manufacturing costs and ensuring driving stability. |
