TRANSMISSION OF WORK VEHICLE

摘要

PROBLEM TO BE SOLVED: To constitute a transmission which inputs a running driving force and a turning driving force opposite to each other to right and left planetary gear mechanisms in which right and left carriers for supporting right and left planetary gears are fixed to right and left axles to that an axle driving force is increased when a wheel is turned and that the planetary gear mechanism is compact. SOLUTION: A running driving force is put into right and left internal gears 22L and 22R in the right and left planetary gear mechanisms 20L and 20R, and a turning driving force is put into right and left sun gears 21L and 21R. A single support shaft 60 is provided supported by the right and left carriers 19L and 19R through a bearing 59 so as to mount the right and left sun gears on the support shaft in capable of free engagement. It is desirable that the support shaft is supported by a supporting member 62 fixed and supported by a transmission case 1.
