Description

【0001】
【発明の属する技術分野】
本発明は、トラクタ等の走行車両のエンジンと、運転部の間で断熱及び遮音を図る遮蔽体の構成に関する。
【0002】
【従来の技術】
従来から、トラクタ等の走行車両のボンネット内に配置するエンジンからの熱や騒音がオペレーターが着座する運転席側に達することを防止するために、ボンネット内のエンジンと運転席側との間に遮蔽板を設けて、エンジンルームを分割して遮蔽するようにしていた。例えば、特開2001−20754号の技術である。
【0003】
【発明が解決しようとする課題】
上記従来技術において、ボンネット内にエンジンを収納して、その後部に配置したメータパネルやハンドルポスト等との間にプレートを立設して前後の部屋に分離し、該プレートには断熱材を貼設して、エンジンからの熱が運転席側に伝わらないようにし、また、熱や騒音が漏れないように、プレートの周縁にはシールを配置していた。
【0004】
しかし、このような構成では、冷却ファンによりエンジンを冷却した後の排風が後方へ流れてきてもプレートにより遮られて後方へ排出することができないために、この排風の流れをよくするにはボンネットの側面に多くの開口部を設ける必要があった。このため、この開口部には騒音を減少するために網やスポンジ等を配置して閉じなければならず、剛性や意匠が劣ることとなっていた。
【0005】
【課題を解決するための手段】
本発明は、以上のような課題を解決するために、次のような手段を用いる。
請求項1においては、走行車両のエンジン(3)を覆うボンネット(4)と、キャビン(9)により被覆された運転部(10)の間に、遮蔽体(30)を設ける構成において、該遮蔽体(30)は、断熱材(31)と遮蔽板(32)より構成し、該遮蔽板(32)の前面に該断熱材(31)を貼設し、該遮蔽体(30)の後部にステアリングコラム(2)を配設し、前記キャビン(9)の前下部の該ステアリングコラム(2)の両側には左右前面ガラス(34・34)を取り付け、前記断熱材(31)の両側を、該左右前面ガラス(34・34)の前面に貼設し、該断熱材(31)の両側は、平面視において内側である左右中央側へ傾斜する方向に、斜めにカットしたテーパ部(31a)を構成し、該テーパ部(31a)は前側が左右前面ガラス(34・34)面の直角方向の面に対して、所定角度(θ)内側へ傾斜した面に構成し、該断熱材(31)の側面のテーパ部(31a)と、前記ボンネット(4)の側面の後端部(4a)との間に、隙間(33)を形成した走行車両のボンネットと運転部の間の構造である。
【0006】
請求項2においては、請求項1記載の走行車両のボンネットと運転部の間の構造において、前記ボンネット(4)の側面の後端部(4a)を、側面視で前記テーパ部(31a)の前後中途部に位置させ、該テーパ部(31a)の後部端が該ボンネット(4)の側面の後端部(4a)の後方に位置し、該テーパ部(31a)の前部端が、該ボンネット(4)の側面の後端部(4a)よりも前方に位置するように構成したものである。
【0007】
請求項3においては、請求項1記載の走行車両のボンネットと運転部の間の構造において、前記断熱材(31)の上面を、後方が下がるテーパ部(31b)に形成し、該テーパ部(31b)の後部上方に、前記キャビン(9)のフロントガラス(35)を配置し、該ボンネット(4)の上面後端にはシール体(36)を固定し、該シール体(36)よりリップ部(36a)を斜め下後方へ突出し、該リップ部(36a)の先端が前記断熱材(31)の上面に接するように延設し、該リップ部(36a)と、該断熱材(31)の上面のテーパ部(31b)と、該フロントガラス(35)により、樋部(37)を形成し、該樋部(37)により、該フロントガラス(35)から落ちる雨水と、該遮蔽体(30)の上方から降ってくる雨水を、左右両側へ流れ落ちるようにガイドする構成としたものである。
【0008】
【発明の実施の形態】
本発明の解決すべき課題及び手段は以上の如くであり、次に添付の図面に示した本発明の一実施例を説明する。図1は本発明の一実施例であるクローラトラクタの側面図、図2はエンジンルームの側面図、図3は同じく平面図、図4は同じく正面図、図5はエンジンルーム後部の遮蔽体の拡大平面図、図6は同じく拡大側面図である。
【0009】
まず、本発明に係るボンネット後部の遮蔽機構を具備した一実施例である、クローラトラクタの概略構成について説明する。図1に示すように、クローラ式走行装置1の前部上方にはエンジン3が配置され、後部上方にはリアミッションケース5が配置されている。エンジン3はボンネット4に覆われて、ボンネット4内をエンジンルーム11としている。該エンジン3は左右下側のエンジンブラケット6・6間に固定されている。
【0010】
ボンネット4の後部にはステアリングコラム2を設け、該ステアリングコラム2上に操向操作を行う丸型の操向ハンドル7を配置し、該操向ハンドル7の後方にシート8を配設し、該ステアリングコラム2とシート8の間の下方にステップ18を配置して、運転部10を構成している。これら運転部10はキャビン9によって覆われている。
【0011】
前記ボンネット4内のエンジンルーム11の構成は、図2、図3に示すように、該エンジンルーム11内にエンジン3やラジエータ20等が収納されており、該ボンネット4の側面及び上面の内側に断熱材22が貼設され、該ボンネット4内の前記エンジンブラケット6の前部上にバッテリー21が載置され、その後部にオイルクーラー、ラジエータ20、冷却ファン23、エンジン3と配置され、その後部に本発明の遮蔽体30が配置されて、エンジンルーム11と運転部10を収納したキャビン9との間を遮蔽する構成としている。
【0012】
図2〜図6に示すように、該遮蔽体30は断熱材31と遮蔽板32よりなり、該断熱材31はゴムやウレタンやスポンジ等により構成され、遮蔽板32は制振材等より構成されて、該遮蔽板32の前面に断熱材31が接着材または両面テープ等によって貼設されている。該遮蔽体30の後部にステアリングコラム2が配設され、キャビン9の前下部両側に左右前面ガラス34・34が取り付けられて、前記断熱材31の両側が左右前面ガラス34・34の前面に貼設されている。
【0013】
前記断熱材31はエンジンルーム11からの断熱及び騒音を吸音して遮断するために十分な厚みを有しており、その上面及び側面の表面はコーティング等の処理によって、水を弾き、空気がスムースに流れるようにしている。該断熱材31の両側は、図5に示すように、平面視において、内側(左右中央側)へ傾斜するように斜めにカットしたテーパ部31aを設けている。つまり、該テーパ部31aは前側が左右前面ガラス34面の直角方向の面に対して、所定角度θ(本実施例では略30度)内側へ傾斜した面としているのである。
【0014】
そして、前記ボンネット4の側面の後端部4aとテーパ部31aの間に隙間33を構成している。つまり、ボンネット4の側面の後方延長上近傍にテーパ部31aの後部端が位置し、テーパ部31aの前端がボンネット4の側面よりも左右内側に配置し、後端部4aよりも前方に位置させているのである。
【0015】
このように構成することによって、前記冷却ファン23によって発生した冷却風はエンジン3を冷却した後ボンネット4後部に至り、断熱材31の左右両側のテーパ部31aにガイドされて、隙間33より機外に排出されるのである。即ち、テーパ部31aは導風板の役目も果たしているのである。そして、この隙間から出た温かい冷却風は左右前面ガラス34に当てられることになり、デフロスターの役目を果たし、左右前面ガラス34の曇りを防止することができ、オペレーターから前下方の視界を確保することができるのである。
【0016】
更に、前記テーパ部31aの前後中途部に前記ボンネット4の側面後端部4aが位置するように構成されている。つまり、ボンネット4の左右両側面の後端部4aは左右前面ガラス34の前面よりも前方に位置するようにし、かつ、断熱材31の前端面よりも後方に位置するようにしている。
【0017】
このように構成することによって、側面視において、ボンネット4の後端と左右前面ガラス34との間の隙間33には、遮蔽体30(断熱材31)が位置するようになり、該隙間33からエンジンルーム内を見ることはできず、外観を向上することがてきるのである。また、ボンネット側面に排風孔を開口すると、内部が見えず、かつ、騒音が出ないように網やスポンジ等によって開口部を蓋する必要があるが、本発明の如く構成することによって、開口部を設ける必要がなく、ボンネットの加工が容易となり、隙間33には網等がないために、内面の全面に断熱材22を貼設することができるため、断熱及び遮音が容易にできる。また、排風に対して抵抗がなく、冷却風が排出されるので、冷却効率も向上できるのである。また、サイドボンネットを着脱する際には、指が前記隙間33に入れることができ、サイドボンネットの端部をつかんで着脱作業を容易行なうことができ、サイドボンネットに把手等を設ける必要がないのである。
【0018】
また、前記断熱材31の上面は、図6に示すように、後方が下がるテーパ部31bが形成され、該テーパ部31bの上方にフロントガラス35が配置されて、該テーパ部31bの後部と前記遮蔽体31とフロントガラス35により樋を形成して、フロントガラス35から落ちる雨水は該樋に沿って左右両側へ流れ落ちるようにしている。そして、ボンネット4の上面後端にはシール体36が固定され、該シール体36にはリップ部36aが斜め下後方へ突出するように構成され、該リップ部36aの先端が断熱材31の上面に接するように延設され、平面視においてはリップ部36aと断熱材31が重複するように配置している。
【0019】
このようにして、上方から降ってくる雨水に対しては、シール体36のリップ部36aによって後方へ流れるようにガイドして、エンジンルーム内に浸入することを防止し、遮蔽体30上面の雨水はリップ部36aと断熱材31とフロントガラス35により形成した樋部37によって左右へガイドして雨水を排水できるようにしているのである。
【0020】
【発明の効果】
本発明は、以上のように構成したことにより、次のような効果が得られる。
請求項1に記載の如く、走行車両のエンジン(3)を覆うボンネット(4)と、キャビン(9)により被覆された運転部(10)の間に、遮蔽体(30)を設ける構成において、該遮蔽体(30)は、断熱材(31)と遮蔽板(32)より構成し、該遮蔽板(32)の前面に該断熱材(31)を貼設し、該遮蔽体(30)の後部にステアリングコラム(2)を配設し、前記キャビン(9)の前下部の該ステアリングコラム(2)の両側には左右前面ガラス(34・34)を取り付け、前記断熱材(31)の両側を、該左右前面ガラス(34・34)の前面に貼設し、該断熱材(31)の両側は、平面視において内側である左右中央側へ傾斜する方向に、斜めにカットしたテーパ部(31a)を構成し、該テーパ部(31a)は前側が左右前面ガラス(34・34)面の直角方向の面に対して、所定角度(θ)内側へ傾斜した面に構成し、該断熱材(31)の側面のテーパ部(31a)と、前記ボンネット(4)の側面の後端部(4a)との間に、隙間(33)を形成したので、エンジンと運転部との間で遮蔽体によって、断熱及び遮音するとともに、テーパ部によって冷却風を機体側方へ排出する導風板の役目を果たすことができ、運転部がキャビン仕様の場合にはキャビンの左右前面ガラスに排風を当て、デフロスタの役目も果たすことができる。
また、前記隙間には手を入れることができ、ボンネットのサイドカバーを持って容易に着脱することができるのである。
【0021】
請求項2に記載の如く、請求項1記載の走行車両のボンネットと運転部の間の構造において、前記ボンネット(4)の側面の後端部(4a)を、側面視で前記テーパ部(31a)の前後中途部に位置させ、該テーパ部(31a)の後部端が該ボンネット(4)の側面の後端部(4a)の後方に位置し、該テーパ部(31a)の前部端が、該ボンネット(4)の側面の後端部(4a)よりも前方に位置するように構成したので、隙間があるにもかかわらず、側方から内部が見えず外観を向上することができたのである。
【0022】
請求項3に記載の如く、請求項1記載の走行車両のボンネットと運転部の間の構造において、前記断熱材(31)の上面を、後方が下がるテーパ部(31b)に形成し、該テーパ部(31b)の後部上方に、前記キャビン(9)のフロントガラス(35)を配置し、該ボンネット(4)の上面後端にはシール体(36)を固定し、該シール体(36)よりリップ部(36a)を斜め下後方へ突出し、該リップ部(36a)の先端が前記断熱材(31)の上面に接するように延設し、該リップ部(36a)と、該断熱材(31)の上面のテーパ部(31b)と、該フロントガラス(35)により、樋部(37)を形成し、該樋部(37)により、該フロントガラス(35)から落ちる雨水と、該遮蔽体(30)の上方から降ってくる雨水を、左右両側へ流れ落ちるようにガイドする構成としたので、簡単な構成で上方からの雨水やフロントガラスから流れ落ちた雨水を樋に沿って側方へ排水することができ、エンジンルーム内への水の浸入を防止することができたのである。
