Abstract
Description
このようなダンプトラックによれば、重心位置がホイールベースの略中央に設定されているため、油圧ショベル等の積込機械で土砂が積み込みやすくなり、荷こぼれを少なくすることができ、また、前輪、後輪に作用する荷重負荷を均等にすることができる、という効果がある。
また、ダンプボディを起こした際、排土側のダンプボディの端部が地面から高い位置となってしまうので、排土の際、土砂等が散らばり、タイヤ等に被ってしまうという課題がある。
また、第2傾斜面部を備えていることにより、排土時、ダンプボディの排土側端部をより地面に近い位置とすることができるため、排土時に土砂等の積載物を散らばりにくくすることができる。
本発明では、前記第1傾斜面部の上端から前記シャーシの前後方向の中心までの寸法が、前記第3傾斜面部の上端から前記シャーシの前後方向までの中心の寸法よりも大きいのが好ましい。
[1]ダンプトラック1の全体説明
図1から図4には、本発明の実施形態に係るダンプトラック1が示されている。図1は、斜視図であり、図2は、走行方向に直交する車幅方向から見た側面図、図3は、上視点から見た平面図、図4は、走行方向から見た側面図である。
ダンプトラック1は、シャーシ2およびダンプボディ3を備え、ダンプボディ3内に土砂等の積載物S(図5参照)を積載して前後双方向に前進走行し、図1における走行方向のX軸のマイナス方向を一方向として排土する。なお、前進走行とは、前後で区別がないため、双方向前進として同じ動きをすることできることをいう。
フレーム6は、シャーシ2の両側端部に走行方向に延出する一対のアッパーサイドメンバ6Aと、一対のロアーサイドメンバ6Bとを備える。上下に離間して配置されるアッパーサイドメンバ6Aおよびロアーサイドメンバ6Bは、先端および後端で複数のバーチカルメンバ6Cによって連結されている。また、車幅方向に配置される一対のアッパーサイドメンバ6A同士は、車幅方向に延びる複数のアッパークロスメンバによって連結され、一対のロアーサイドメンバ6B同士は、車幅方向に延びる複数のロアークロスメンバによって連結されている。すなわちフレーム6は、シャーシ2の走行方向から見て直方体状の骨組を有している。
エンジン7は、フレーム6のアッパーサイドメンバ6Aおよびロアーサイドメンバ6Bの間に設けられ、上部がアッパーサイドメンバ6Aから突出している。
また、エンジン7は、タイヤ4の後方側に設けられ、タイヤ4およびタイヤ5の回転中心で規定されるホイールベースW内に配置されており、ダンプトラック1の重心が、シャーシ2の略中央となっている。
制御装置9は、ダンプトラック1の走行を制御し、シャーシ2の排土側端部P(図5参照)に設けられる障害物検出センサや、エンジン7に設けられる温度センサ、タイヤ4、5に設けられた回転センサ等のセンサ情報に基づいて、ダンプトラック1の走行制御を行う。
ホイストシリンダ10は、制御装置9の後方に、車幅方向に2つ設けられ、その基部はフレーム6に回転可能に設けられ、先端はダンプボディ3の排土側端部Pとは反対側の端部下面に回転可能に設けられている。
ホイストシリンダ10は、図示を略したが、フレーム6内に設けられた油圧ポンプから作動油を受けて動作し、油圧ポンプは、エンジン7によって駆動される。
ダンプトラック用ダンプボディとしてのダンプボディ3は、図3に示されるように、平面視でシャーシ2の走行方向の全長および車幅方向の全幅を覆っており、ダンプボディ3の排土側端部Pは、シャーシ2の端部から延出している。ダンプボディ3は、図3に示されるように、平面視矩形状の箱状体として構成されている。なお、ダンプボディ3が矩形状で、シャーシ2も前後方向に同じ矩形状に作られているため、前後方向には区別されていない。このため、双方向に前進できる(便宜上前後として説明する。)。また、ダンプボディ3は、図示を略したが、バーチカルメンバ6Cの上端に設けられたボディマウント上に載置される。
ボディマウントは、フレーム6の上面に設けられ、ダンプボディ3の荷重をバーチカルメンバ6Cに伝達する。
ダンプボディ3は、フレーム6の排土側の走行方向の端部にヒンジ12を介して起伏可能に装着されている。ダンプボディ3は、前述したホイストシリンダ10が伸長することにより、フレーム6のヒンジ12を回転軸として起伏する。
底面部14は、図3および図5に示されるように、シャーシ2の略中央部に配置され、シャーシ2の走行方向および車幅方向に水平に延びる鋼製板状体から構成されている。
第1傾斜面部15は、底面部14の後端から斜め上方に立ち上がる鋼製板状体から構成され、底面部14を水平面としたときに、立ち上がり角度θ1は、例えば12°とされている。
第3傾斜面部としての前面部17は、底面部14の前端から斜め上方に立ち上がる鋼製板状体から構成され、底面部14を水平面としたときに、前面部17の立ち上がり角度θ3は、第1傾斜面部15の立ち上がり角度θ1よりも大きくなっていて、例えば40°とされている。
これにより、ダンプボディ3に土砂等の積載物Sを積み込むと、積載物Sの山の重心位置Gがシャーシ2の略中央になる。また、積載物Sをダンプボディ3に積み込んだ際、積載物Sの前後方向の長さ寸法D0と、積載高さ寸法H0の比(H0/D0)は、略0.25となる。
このような本実施形態によれば、以下のような効果がある。
ダンプボディ3が、第2傾斜面部16を備えていることにより、排土時、ダンプボディ3の排土側端部Pをより地面に近い位置とすることができるため、排土時に土砂等の積載物Sを散らばりにくくすることができる。
また、積載物Sをシャーシ2の前後方向中心から排土側の部分と、反対側の部分での積載比率を調整することができるので、積載物Sの重心位置Gをシャーシ2の前後方向中心近傍に設定することができ、シャーシ2の前後の負担を均等にして、搬送中に荷こぼれ等が生じることを防止できる。
前面部17の立ち上がり角度θ3を、第1傾斜面部15の立ち上がり角度θ1よりも大きくすることにより、ダンプボディ3の前面部17側の積載物Sを排土するまでの距離を短くすることができるので、荷流れを一層良好にすることができる。
積載物Sをシャーシ2の走行方向中心から排土側の部分と、反対側の部分での積載比率を調整することができるので、積載物Sの重心位置Gをシャーシ2の走行方向中心近傍に設定することができる。
本発明は、前述した実施形態に限定されるものではなく、以下のような変形も含まれる。
前述した実施形態では、ダンプトラック1は、無人で走行するオフロードダンプトラックであったが、本発明はこれに限らず、背景技術で述べたキャブを備えたダンプトラックに本発明を適用してもよい。
特に、背景技術で説明した先行技術である特許文献1(特開昭62-50144号公報)に記載された発明には、好適に適用することができる。
その他、本発明の実施の際の具体的な構造および形状等は、本発明の目的を達成できる範囲で他の構造等としてもよい。
