Power transmission arrangement of a working vehicle and transmission for the working vehicle

摘要

In a transmission for a working vehicle, a PTO input shaft is located with its rotational axis extending in a vehicle lengthwise direction substantially at a widthwise center of a transmission case along a vehicle width direction. A running power input shaft is located with its rotational axis extending in the vehicle lengthwise direction substantially at the same position as that of the PTO input shaft along the vehicle width direction and at a lower side of the PTO input shaft. The transmission case provides an accommodation space for accommodating a differential gear unit, which space is displaced to a first lateral side of the vehicle along the vehicle width direction. A running power transmission shaft is located on the front side of the space with its axis extending in the vehicle lengthwise direction, and the running power input shaft, the running power transmission shaft and the differential gear unit are interlocked to each other via a running power gear train. The mid-PTO shaft is located within the transmission case closer to a second lateral side of the transmission case along the vehicle width direction and lower side of the transmission case with its axis extending in the vehicle lengthwise direction. A PTO power transmission shaft is located within the transmission case closer to the second lateral side along the vehicle width direction with its axis extending in the vehicle lengthwise direction and its rear end reaching to the rear side of the transmission case. A mid-PTO gear train is located within the transmission case closer to a rear side thereof for interlocking the PTO power transmission shaft with the mid-PTO power transmission shaft.
