Description

【０００１】
【発明の属する技術分野】
本発明は、車両に装備されるエンジンやラジエータ等を、収納し覆うボンネットカバーとラジエータの取付構成に関する。
【０００２】
【従来の技術】
従来、エンジンやラジエータ等をボンネットカバーによって覆い、騒音の発生を抑え、容易に手等が触れないようにし、また、保護している。
これらのボンネットカバーは容易に着脱できるようにして、調整や修理、交換等のメンテナンスが容易にできるようにされている。
このボンネットカバーは、エンジン前部を被装して、冷却用の空気を取り入れるフロントカバーや、エンジン側部を被装するサイドカバー等により構成され、これらの組み付けを容易にした技術が公知となっている。
例えば、特開平７−２４２１８３号の技術である。
【０００３】
【発明が解決しようとする課題】
しかし、従来のボンネットカバーを組み付ける機枠は、エンジンの配設位置より前方側に立設され、エンジンを冷却するラジエータを機枠とエンジンの間位置に配設して別構成となっており、ボンネットカバーの機枠の前方にはバッテリーが配設されている。これら全ての機器を覆う為には機体フレームを前後方向に長くする必要があり、機体全長も長くなっていた。
また、ラジエータを支持する支持部材とボンネットカバーの機枠は別構成であるために部品点数が多くなり、コストアップとなっていた。
【０００４】
【課題を解決するための手段】
本発明はこのような問題点を解消するために、次のような手段を用いる。
ボンネットカバー内部のエンジンフレーム１上に、ラジエータ２をサポート枠３により支持し、且つ該サポート枠３に、ボンネットカバーの取付部を設けた構成において、エンジンフレーム１・１の上部にステー３０・３０を固設し、該ステー３０・３０にはラジエータ２を弾性支持する載置部材３１・３１を支持し、前記ステー３０には管部３０ｂを形成し、一方、平面断面視「コ」字状に形成された枠体のサポート枠３の下端には、枢支孔３ｂを開口し、該枢支孔３ｂと前記管部３０ｂとを合わせて、ステー３０にヒンジを構成し、サポート枠３の下端を回動可能とし、前記サポート枠３・３の上部と、前記ラジエータ２の上部を連結固定するものである。
【０００５】
【発明の実施の形態】
本発明の実施の形態を、添付の図面を基に説明する。
図１はエンジンフレーム上にエンジンとラジエータを配置した側面図、図２はボンネットカバーを外した状態の分解斜視図、図３は右側はラジエータの組み付け前の正面図であり、左側はラジエータの組み付け時の正面図、図４は同じくラジエータを組み付けた後の状態を示す正面図、図５はサポート枠の枢支構成を示す斜視図である。
【０００６】
トラクタのエンジンＥを覆うボンネットカバーと、ラジエータを支持したサポート枠の実施例を説明する。
図１、図２において、エンジンフレーム１上にエンジンＥが載置固定され、該エンジンフレーム１上のエンジンＥの前部にラジエータ２が配置され、該ラジエータ２は、エンジンフレーム１の前後中途部より左右それぞれ立設したサポート枠３・３の内側に固定されている。そして、ラジエータ２の前部にバッテリー８が載置され、エンジンＥの後部に図示しない燃料タンクが配置され、これらはボンネット４及びボンネットカバーによって覆われる。
ボンネットカバーは、フロントカバー５、サイドカバー６Ｌ・６Ｒよりなり、エンジンＥ、ラジエータ２、バッテリー８の上方はボンネット４によって、前方はフロントカバー５、側方はサイドカバー６Ｌ・６Ｒによってそれぞれ覆われる。該フロントカバー５は合成樹脂によって製作され、軽量化を図り、コスト削減を図っている。ボンネット４及びサイドカバー６Ｌ・６Ｒは、鋼板のプレス加工によって制作される。前記ボンネット４の後部は門型フレーム７の上部に回動自在に枢支され、ボンネット４の後方には図示しないダッシュボードが配置されている。
【０００７】
次に、前記フロントカバー５の着脱構成を説明する。
フロントカバー５の下縁部左右両側には係合突起１０・１０が下方に突出形成される一方、エンジンフレーム１の前部左右側方には、ステー１１・１１が突設され、該ステー１１・１１に係合孔１１ａ・１１ａが開口されて、前記係合突起１０・１０を挿入できるようにしている。
また、前記フロントカバー５の上縁部５ａに、係合孔５ｂ・５ｂが開口されている。一方、前記係合孔５ｂ・５ｂに嵌入する係合部材Ａが、フロントカバー５に対する取付体となるサポート枠３の前面に配置されている。
前記係合部材Ａは湾曲部を有する板バネ１５より構成され、該板バネ１５の湾曲部を係合孔５ｂに挿入することで、フロントカバー５を着脱自在に固定している。
【０００８】
次に、サイドカバー６Ｌ・６Ｒの着脱構成を説明する。サイドカバー６Ｌ・６Ｒの下縁部にはそれぞれ係合突起２０・２０が下方へ突出形成される一方、エンジンフレーム１の中央部左右側方と後部左右側方に、ステー２１・２１が突設され、該ステー２１・２１に係合孔２１ａ・２１ａが開口されて、前記係合突起２０・２０が、係合孔２１ａ・２１ａに挿入できるようにしている。
また、サイドカバー６Ｌ・６Ｒの上部の前後箇所には、被係合部材２２・２２がそれぞれ溶着固定されている。該被係合部材２２に孔を開口している。一方、被係合部材２２・２２の孔に係合する係合部材Ｂ・Ｂが、サイドカバー６Ｌ・６Ｒの取付体となるサポート枠３の外側面と門型フレーム７に夫々取り付けられている。係合部材Ｂは、フロントカバー５の場合と同様に構成した湾曲部を有する板バネ１５より構成されている。前側の係合部材Ｂは、サポート枠３の外側面に固定されており、後ろ側の係合部材Ｂは、門型フレーム７の内側面に固設しており、各係合部材Ｂの板バネ１５の湾曲部をサイドカバー６Ｌ・６Ｒの被係合部材２２・２２の係合孔に挿入することで、サイドカバー６Ｌ・６Ｒを着脱自在に固定している。
【０００９】
次に、本発明のサポート枠３を用いてラジエータ２を支持する構成について図３、図４を用いて説明する。
前記ラジエータ２の上部２ａの左右側面に、ブラケット２ｂ・２ｂが固着され、該ブラケット２ｂの内側に固定ナット２５が溶着され、該固定ナット２５に後述するサポート枠３の上部に横架した固定ボルト３３を螺合できるようにしている。前記ラジエータ２の下部２ｃは、合成樹脂によって構成され、該下部２ｃの底面左右両側には係合突起２ｄ・２ｄが一体的に突出している。
【００１０】
一方、エンジンフレーム１・１の前後途中部の上部に、ステー３０・３０が固設され、該ステー３０は途中部を左右外側に屈曲して正面視逆Ｌ字状に構成し、垂直部をエンジンフレーム１に固設し、水平部には台座３０ａを形成している。該台座３０ａにラジエータ２を載置して弾性支持するための載置部材３１が嵌合され、該載置部材３１は、上下方向に軸芯を有する係合孔３１ａが開口され、該載置部材３１・３１の係合孔３１ａ・３１ａに前記ラジエータ２の係合突起２ｄ・２ｄを挿入して、ラジエータ２の下部２ｃ底面を載置部材３１・３１上に載置して、位置決め固定する。
そして、該載置部材３１は、ゴムや樹脂等の弾性部材により構成されておりラジエータ２を防振支持する構成としている。また、本実施例では載置部材３１は台座３０ａを貫通して固定しているが、台座３０ａの上面に載置固定することもできる。
【００１１】
また、前記ステー３０の外側端部には、略管状に湾曲させた管部３０ｂが形成され、一方前記サポート枠３は、平面断面視「コ」字状に形成された枠体として、サポート枠３の下部は、下部タンク２ａの形状に合わせて内側へ傾斜させ、下端には取付部３ａ・３ａを突出して枢支孔３ｂ・３ｂが開口されている。該枢支孔３ｂ・３ｂと前記管部３０ｂとを位置を合わせ、枢支孔３ｂ・３ｂと管部３０ｂに枢支ボルト３２を挿入し、枢支ボルト３２の端はナット３５によって螺合して、ステー３０の外側端部にサポート枠３の下端を枢支し、サポート枠３を枢支ボルト３２を中心に回動可能とし、ヒンジ状に構成している。また、前記サポート枠３の取付部３ａより上方を、直線状に形成しラジエータ２の側面を嵌合できるようにしている。
【００１２】
また、左右の前記サポート枠３・３の上部には、各々固定ボルト３３・３３が横架され、該固定ボルト３３・３３が内側に向かって突出され、サポート枠３・３を直立したときに、左右の固定ボルト３３・３３の内端が対向するように配置している。更に、前記サポート枠３上部の開放面の内側にカラー３４が配設され、固定ボルト３３を挿入して、組立時に前述したラジエータ２上部の固定ナット２５に螺合できるようにガイドしている。
【００１３】
そして、エンジンフレーム１・１にラジエータ２を固定するには、先ず、その下端をステー３０に枢支したサポート枠３を図３右側に示す様に外側に傾倒した状態にして、ラジエータ２を上方よりサポート枠３の中に差し込み、ラジエータ２下部の係合突起２ｄ・２ｄを載置部材３１・３１の係合孔３１ａ・３１ａに挿入して、下部２ａ底面を載置部材３１・３１上に載置し、そして、左右の前記サポート枠３・３を図３の矢印のように内側に回動して直立させ、サポート枠３上部の固定ボルト３３を、ラジエータ２側の固定ナット２５に螺合して締め付けることで、エンジンフレーム１・１上にサポート枠３と載置部材３１とを介して図４に示すようにラジエータ２を側方より挟持して、ラジエータ２を防振支持して固定する。そして、直立状態となったサポート枠３の係合部材Ａにフロントカバー５を固定し、また、係合部材Ｂにサイドカバー６Ｌ・６Ｒを固定する。
【００１４】
【発明の効果】
このように構成したことによって、次のような効果を奏するのである。
ボンネットカバー内部のエンジンフレーム１上に、ラジエータ２をサポート枠３により支持し、且つ該サポート枠３に、ボンネットカバーの取付部を設けた構成において、エンジンフレーム１・１の上部にステー３０・３０を固設し、該ステー３０・３０にはラジエータ２を弾性支持する載置部材３１・３１を支持し、前記ステー３０には管部３０ｂを形 成し、一方、平面断面視「コ」字状に形成された枠体のサポート枠３の下端には、枢支孔３ｂを開口し、該枢支孔３ｂと前記管部３０ｂとを合わせて、ステー３０にヒンジを構成し、サポート枠３の下端を回動可能とし、前記サポート枠３・３の上部と、前記ラジエータ２の上部を連結固定するので、ラジエータを支持するサポート枠にボンネットカバーを取付け支持したことによって、個別にラジエータとボンネットカバーを支持する支持部材を設ける必要がなくなり、部品点数を減らすことができる。
そして、ボンネットカバー内の部品点数を減らすことによって、煩雑な内部構成を簡潔にすることができ、ラジエータを組立作業する空間を広くして、ラジエータを組み付け易くすることが出来る。
また、同時に、支持部材を減らした分において、ボンネットカバーを小型化し、また、機体の全長を短くすることができ、軽量化を図り、コスト削減を図ることができる。
