Description

本発明は農作業或いは土木作業などを行うトラクタなど作業車のボンネット装置に関する。   The present invention relates to a bonnet device for a work vehicle such as a tractor that performs agricultural work or civil engineering work.

ボンネット本体に対し前側のフロントグリルを分割させて取外し自在に連結させるようにした技術がある。（例えば、特許文献１参照）   There is a technology in which the front grille on the front side is divided with respect to the bonnet main body and is detachably connected. (For example, see Patent Document 1)

特開平７―８９４５６号公報JP-A-7-89456

上記の如き、ボンネット前側のフロントグリルとボンネット本体とが分割構造にあって、フロントグリルが一体樹脂タイプで、ボンネットが上・中・下のアッパ部・サイドアッパ部・サイドロア部に３分割されたタイプのボンネット構造においては、これらを機体に組付時にボンネット各部とフロントグリルの合せ部には各部品の取付寸法誤差やフロントグリル自体の変形（重力による）などでズレが発生し、ズレなどのない外観美の良好な合せ部を得るには調整に多大な労力と時間を要するものであった。   As described above, the front grille and bonnet body on the front side of the bonnet have a split structure, the front grille is an integral resin type, and the bonnet is divided into three parts: upper, middle, lower upper, side upper, and side lower. In the bonnet structure of the type, when these are assembled to the fuselage, the bonnet parts and the front grille are misaligned due to mounting dimension errors of each part or deformation of the front grille itself (due to gravity). It took a lot of labor and time for adjustment to obtain a good mating part with no appearance.

そこで本発明は、ボンネット前部のフロントグリルを一体樹脂で形成すると共に、フロントグリルを取付けるフレームにフロントグリルの左右位置を調整する調整用ブラケットを設けたものである。   Therefore, according to the present invention, the front grille at the front part of the bonnet is formed of an integral resin, and an adjustment bracket for adjusting the left and right positions of the front grille is provided on the frame for attaching the front grille.

また、フロントグリル左右片側のフレームの上下方向に略等間隔に調整用のブラケットを複数設けたものである。   Further, a plurality of adjustment brackets are provided at substantially equal intervals in the vertical direction of the frame on the left and right sides of the front grill.

而して本発明によれば、ボンネット前部のフロントグリルを一体樹脂で形成すると共に、フロントグリルを取付けるフレームにフロントグリルの左右位置を調整する調整用ブラケットを設けたことによって、フロントグリルの取付時にあっては、ボンネット本体側が例えば上・中・下のアッパ部・サイドアッパ部・サイドロア部に３分割された状態においてもこれら各部とグリルの合せ部をズレなどの少ない適性に調整した良好な取付けを容易に可能とさせるものである。   Thus, according to the present invention, the front grille at the front part of the bonnet is formed of an integral resin, and the bracket for adjusting the left and right positions of the front grille is provided on the frame to which the front grille is attached. In some cases, even when the bonnet body side is divided into, for example, an upper, middle, and lower upper part, side upper part, and side lower part, these parts and the matching part of the grill have been adjusted to be suitable for less misalignment. It makes it easy to install.

また、フロントグリル左右片側のフレームの上下方向に略等間隔に調整用のブラケットを複数設けたことによって、ボンネット本体側の上・中・下のアッパ部・サイドアッパ部・サイドロア部などに対応させたフロントグリルの微量調整自在な取付けを可能とさせて、フロントグリルの取付性を向上させるものである。   In addition, by providing multiple adjustment brackets at approximately equal intervals in the vertical direction of the frame on the left and right sides of the front grille, it is possible to correspond to the upper, middle, and lower upper parts, side upper parts, side lower parts, etc. on the bonnet body side. The front grille can be mounted with a small amount of adjustment, thereby improving the mountability of the front grille.
