PROBLEM TO BE SOLVED: To achievement improvement in a support constitution of a truck frame and an oscillation support shaft in a semi-crawler device.SOLUTION: A semi-crawler type work vehicle integrally comprises final speed reduction cases 16L, 16R at respective ends of rear axle cases 15L, 15R. In the work vehicle, drive sprockets 10L, 10R of crawler travel devices 3L, 3R are mounted to drive shafts 9L, 9R of the final speed reduction cases 16L, 16R, and a support shaft frame 19 is fixed onto an underside of a transmission case 5, shaft support parts 20L, 20R are configured at left and right ends of the support shaft frame 19. The work vehicle is so configured as to comprise oscillation shafts 21L, 21R at the shaft support parts 20L, 20R, and to oscillatively support truck frames 17L, 17R with respect to the oscillation shafts 21L, 21R. Front and rear stretched wheels 11, 12 and idle wheels 13, 13 are supported on the truck frames 17L, 17R, and left and right ends of the support shaft frame 19 are connected and fixed to the left and right final speed reduction cases 16L, 16R.SELECTED DRAWING: Figure 6
【課題】セミクローラ装置のトラックフレーム及び揺動支軸の支持構成の改善を図る。【解決手段】リヤアクスルケース15L,15Rの各端部に最終減速ケース16L,16Rを一体的に備え、最終減速ケース16L,16Rに支持された駆動軸9L,9Rにクローラ走行装置3L,3Rの駆動スプロケット10L,10Rを装着し、前記トランスミッションケース5の下面に支軸フレーム19を固定し、該支軸フレーム19の左右端部に軸支持部20L,20Rを構成し、これら軸支持部20L,20Rに揺動軸21L,21Rを備え、これら揺動軸21L,21Rに対してトラックフレーム17L,17Rを揺動自在に支持する構成とし、該トラックフレーム17L,17Rには前後の張設輪11,12及び遊転輪13,13を支持し、この支軸フレーム19の左右端部を前記左右の最終減速ケース16L,16Rに連結固定する。【選択図】 図6
