DRIVING STRUCTURE OF REAR WHEEL OF AGRICULTURAL TRACTOR

摘要

PURPOSE:To strengthen driving structure by reducing a burden of load of a fixing structure, by a method wherein inside edges of an output and intermediate shafts are born by bearings provided on opposed parts of the shafts. CONSTITUTION:Intermediate cases 7 are fixed on both sides of a transmission case 3 and outside parts of a right and left output shafts 4 of a differential gear 1 are born by bearings 19 at the upper parts of the cases 7. Intermediate shafts 5 to be interlocked with each other through the output shafts 4 and geared speed reduction mechanism 6 are born by bearings 20 of the lower parts of the side walls of the transmission case 3 and bearings 21 of the lower parts of the intermediate cases 7, axle cases 10 are made to position within dented spaces 12 to be formed by rims 11A of rear wheels and made to bear by bearings 22. Then axle shafts 8 to be interlocked with each other through the intermediate shafts 5 and the geared speed reduction mechanism 9 are born by bearings 18 at the lower parts of the axle cases 10 under a state wherein rear wheels 11 are born at their outside ends.
