PROBLEM TO BE SOLVED: To provide a compact axle driving device comprising a multi-stage shift mechanism having longitudinally extending transmission shafts to combine with an engine having a longitudinally extending crank shaft.SOLUTION: A bevel gear disposed as an output member in a multi-stage shift mechanism having multiple longitudinally extending transmission shafts and a bevel gear disposed in a speed-reducing interim shaft arranged in parallel to a pair of differential yoke shafts laterally extending and provided in a differential mechanism. An axle driving device comprises a single vehicle axle drive case encasing a speed-reducing mechanism including the multi-stage shift mechanism, the differential mechanism and the speed-reducing interim shaft.SELECTED DRAWING: Figure 5
【課題】前後方向のクランク軸を有するエンジンと組み合わせられるように前後方向の伝動軸を有する多段変速機構を備えたコンパクトな車軸駆動装置を構成する。【解決手段】前後方向の複数の伝動軸を有する多段変速機構の出力部材としてのベベルギアと、差動機構の有する左右延伸状の一対のデフヨーク軸に対し平行に配置される減速中間軸に設けたベベルギアとを噛合する。該多段変速機構、該差動機構、及び該減速中間軸を有する減速機構を、単一の車軸駆動ケースに収容して、車軸駆動装置を構成する。【選択図】図5
