キャブ2には、ブルドーザ1のオペレータが座るためのシートや各種操作のためのレバー、ペダルおよび計器類が内装されている。また、キャブ2は、転倒時運転者保護構造(ROPS構造)39を有しており、車両本体3に配置されている。転倒時運転者保護構造(ROPS構造)39は、ISO3471として規格化されている。
車両本体3は、エンジンフード31、排気管32、左右の走行装置33、第1収容部5、第2収容部34、及び、これらを支持するメインフレーム(図示せず)を含む。
作業機4は、ブレード41、アーム部材42、および、油圧シリンダ43,44を含む。ブレード41は、エンジンフード31の前方に設けられている。つまり、エンジン11は、ブレード41の後方に配置される。ブレード41は、キャブ2の左右方向の幅よりも大きな幅を有している。また、ブレード41の下端部が地面に接触している状態において、ブレード41の上端部は、エンジンフード31の上面よりも下方に位置しており、エンジンフード31の上面は、キャブ2内のシートに着座したオペレータの視点と、ブレード41の上端部とを結んだ仮想線よりも下方に位置している。アーム部材42は、作業機4を支持する。アーム部材42の一端が車両本体3に接続され、アーム部材42の他端がブレード41に接続されている。油圧シリンダ43,44は、伸縮することによって、ブレード41を所望の方向へ傾けたり、移動させたりする油圧アクチュエータである。
図3を参照すると、キャブ2の下部2aは、取付部27と床部28と床支持部29とを含む。ここで、キャブ2の下部2aとは、後部側面24の下端よりも下にあたるキャブ2の部分を指す。取付部27は、オペレータが着座した際に、オペレータの手の肘の高さに相当する上面を有する。取付部27には、操作レバーなどが取り付けられる。床部28は、オペレータが足を置く床に相当する。床支持部29は、取付部27と床部28とを接続する。床支持部29は、正面視において、下方且つ内方に傾斜している。つまり、キャブ2の下部2aの側面は、正面視において、下方且つ内方に傾斜している。
つぎに、本発明の第2の実施形態に係るブルドーザ1aについて説明する。ブルドーザ1aは、第1収容部と、還元剤タンクモジュールを除いて、第1の実施形態のブルドーザ1と殆ど同じである。したがって、第2の実施形態の第1収容部を第1収容部5aとし、還元剤タンクモジュールを還元剤タンクモジュール6aとし、第1の実施形態と相違する点を中心に説明する。なお、第1の実施形態と同じ構成については、第1の実施形態と同じ符号を付しており、詳細な説明を省略する。
本実施形態に係るブルドーザ1,1aは、以下の特徴を有する。
(1)ブルドーザ1,1aでは、上面視において、還元剤タンク60,60aの少なくとも一部は、キャブ2と重畳する。したがって、還元剤タンク60,60aの一部をキャブ2の下部の側方のスペースに設けることによって、還元剤タンク60,60aの容量を大きくすることができる。したがって、オペレータの側方視界性を十分に確保しつつ、還元剤タンク60,60aの容量を大きくすることができる。
