<p><P>PROBLEM TO BE SOLVED: To constitute a traveling transmission system of a working vehicle, in which speed is changed with gears in multiple stages, by a transmission case narrow in vehicle width and short in longitudinal direction using multiple-disc clutches and synchronizing clutches, which enables shift control to be performed easily. <P>SOLUTION: In the traveling transmission system of a working vehicle, revolutions of an input shaft 21 input from an engine output shaft 20 branch to a low-speed transmission shaft 34 and a high-speed transmission shaft 32 by high/low hydraulic multiple-disc clutches 24, 25 of the same structure. The revolutions of the low-speed transmission shaft 34 and the high-speed transmission shaft 32 are each transmitted to rear wheels 3 by changing the speed by a plurality of transmission systems 36, 42, 58, 71. The high/low hydraulic multiple-disc clutches 24, 25 are disposed at right and left positions inside the lower side of a descending inclined part 8c where the top surface of the transmission case 8 descends downward and inclines at the front part thereof. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
