Zusammenfassung: | PROBLEM TO BE SOLVED: To improve the arrangement of a hydraulic pump unit, and to enhance maintenance performance without impairing the balance of a machine body.SOLUTION: In a working vehicle having hydraulic motors Mr for driving left and right wheels 21, and making the hydraulic motors Mr rotationally interlock with each other by receiving the supply of pressure oil from a hydraulic pump unit P, an axle 20 which oscillates around a pivot shaft 19 while approximating a rear part of an engine 13 is arranged, the wheels 21, 21 are supported to both sides of the axle 20 in order to interlock with each other by a steering mechanism S, and the hydraulic pump unit P is arranged at an upper part of the axle 20. The hydraulic pump unit P can be supported by utilizing a frame portion which is rigidly constituted by a support constitution of the axle 20 and the pivot shaft 19. Furthermore, frame parts 16 which are connected to an engine 13, and oppose each other in the left-and-right direction are connected by a first plate 40 in the vertical direction, and the hydraulic pump unit P can be arranged in the vicinity of the engine 13 so as to be detachable in an upper part of the first plate.
【課題】油圧ポンプユニットの配置を改善し、機体バランスを損なわず、メンテナンス性の向上を図る。【解決手段】左右車輪21を駆動するための油圧モータMrをそれぞれ備え、油圧ポンプユニットPからの圧油の供給を受けて各油圧モータMrを回転連動する作業車両において、エンジン13の後方に接近してピボット軸19回りに揺動する車軸20を設け、この車軸20の両側に前記車輪21,21を操舵機構Sによって連動すべく支持し、車軸20上方に油圧ポンプユニットPを配置する。車軸20やピボット軸19支持構成により強固に構成されるフレーム部分を利用して該油圧ポンプユニットPを支持できる。又、エンジン13に連結され左右対向するフレーム部16間を縦方向の第1プレート40で連結し、この上部に、油圧ポンプユニットPを着脱自在にして、エンジン13近傍に配置できる。【選択図】 図6 |
