本発明は安定した状態にて荷箱をダンプさせることがで
きるようにするとともにヒンジ取は部を堅牢にできるよ
うにしたダンプトラックのヒンジ取吋構造に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hinged structure for a dump truck, which allows a cargo box to be dumped in a stable state and also makes the hinged part robust.
従来、この種のダンプトラックのヒンジ取は構造にあっ
ては、主メンバのみに取けける構造であるため、左右一
対のヒンジ間隔を広くして、ダンプ時の安定を計ること
もできず、又ダンプ時には主メンバに大きな負荷が集中
することになるため、主メンバが破損しやすくなる欠点
がある。Conventionally, the structure of this type of dump truck hinge was such that it could only be attached to the main member, so it was not possible to widen the distance between the left and right hinges to ensure stability during dumping. Furthermore, since a large load is concentrated on the main member during dumping, there is a drawback that the main member is easily damaged.
本発明は上記問題点を鑑み、特に上部ヒンジを主メンバ
の底面と主メンバと直交状に横設したクロスメンバの底
面とに跨がって取はけるようにして取吋部を堅牢にする
とともに左右一対のヒンジ間隔をできるだけ幅広に取り
、ダンプ時の安定度を高めることができるようにしたダ
ンプトラックのヒンジ取は構造を提供するものである。In view of the above-mentioned problems, the present invention provides a structure in which the upper hinge is installed across the bottom surface of the main member and the bottom surface of a cross member disposed horizontally orthogonally to the main member, thereby making the recessed part more robust. In addition, the hinge structure of the dump truck provides a structure in which the distance between the left and right hinges is made as wide as possible to improve stability during dumping.

The inner boss 15 has a substantially triangular shape, as is clear from FIG. Further, the vertical surface 12 of the inner bracket 13 is welded to the outer surface of the lower part of the main member 6, and the horizontal surface 11 of the inner bracket 13 is welded to the bottom surface of the cross member 8 on the outer side of the main member 6.

。As described above, the present invention horizontally installs a cross member perpendicular to the main member at the rear of the packing box girder, and also installs a support member horizontally on the subframe corresponding to the cross member so that the upper hinge is connected to the bottom surface of the main member. By adopting a hinge mounting structure in which the outer surface of the main member and the bottom surface of the cross member are fixed by face-to-face contact, and the lower hinge is attached to the support member relative to the upper hinge, the load is transferred to the cross member in the middle. Since the main member is separated from the main member and concentrated on the hinge, the load on the main member is reduced by the load on the cross member, which eliminates the need to reinforce the rear part of the main member as in the past. The structure of the parts is simple and sturdy.
又上部ヒンジと主メンバとクロスメンバとの相互間は面
接合して溶接結合されているため捩れに対しては非常に
強いものとなる。Furthermore, since the upper hinge, main member, and cross member are joined face-to-face and welded, they are extremely resistant to torsion.
