MOTIVE POWER PART COOLING DEVICE OF WORK VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a motive power part cooling device of a work vehicle, in which rotation direction of a fan can be quickly changed.SOLUTION: The motive power part cooling device of a work vehicle includes: a first input part 61 and a second input part 62 which each receive power from an engine 20 and are each rotated by the power; a first shaft 81 rotated by the power of the engine 20 and outputting the power to the cooling fan 32 side; a first clutch 76 switching connection and interruption of transmission between the first input part 61 and the first shaft 81; a second shaft 82 rotated by the power transmitted from the second input part 62; a second clutch 77 switching connection and interruption of transmission between the second input part 62 and the second shaft 82; a switching mechanism 95 switching between the connection and interruption of the transmission at the first clutch 76 and the connection and interruption of the transmission at the second clutch 77; and a power transmission device 90 transmitting the power from the second shaft 82 to the first shaft 81 in the direction where the rotation direction of the first shaft 81 becomes the opposite direction.
