Abstract
There is provided a work vehicle including an oil outlet port and a partition part. The oil outlet port opens to a bottom portion in one end side of a transmission case in a vehicle body front-back direction and a vehicle body left-right direction. The oil outlet port takes out a lubricating oil from an interior of the transmission case. The partition part divided an internal space of the transmission case into a first space zone along a sidewall portion of the transmission case, and a second space zone other than the first space zone. The partition part brings the first space zone into a sealed state.
Claims5
A work vehicle comprising:
- a gear transmission configured to vary power from a power source and output the power to a traveling device;
- a transmission case containing the gear transmission;
- and
- an oil outlet port opening to a bottom portion in one end side of the transmission case in a vehicle body front-back direction, the oil outlet port being configured to take out a lubricating oil from an interior of the transmission case, wherein
- the work vehicle includes a partition part dividing an internal space of the transmission case into a first space zone along a sidewall portion of the transmission case, and a second space zone other than the first space zone on another end side in the vehicle body front-back direction of the transmission case, the partition part keeping the first space zone in a sealed state,
- the oil outlet port is disposed at an upper portion and a lower portion in the bottom portion;
- the bottom portion includes a communication chamber formation member disposed on an outer surface of a sidewall portion of the transmission case, the communication chamber formation member being configured to form a communication chamber between itself and the sidewall portion;
- the oil outlet port at the upper portion opens to an upper portion of the communication chamber formation member;
- the oil outlet port at the lower portion opens to a lower portion of the communication chamber formation member;
- and
- a communication hole allowing the communication chamber to communicate with an internal space of the transmission case opens to a portion of the sidewall portion which is opposed to the oil outlet port at the lower portion.
