  • Publication number: 20240418256
    Abstract: A transmission case contains a first power transmission shaft, a second power transmission shaft below the first power transmission shaft, a first power transmission gear attached to the first power transmission shaft, and a second power transmission gear attached to an end of the second power transmission shaft and meshing with the first power transmission gear at a meshing portion. A first cover covers a portion of the second power transmission gear on a first side opposite to a second side toward which the second power transmission shaft protrudes, and covers the end of the second power transmission shaft. A second cover covers a radially outward portion of the second power transmission gear except for the meshing portion.

  • Patent number: 12152661
    Abstract: There is provided a work vehicle including a partition wall to keep partition between a first space zone as part of an internal space of the transmission case in which a differential mechanism is located and a second space zone as part of the internal space which is adjacent to the first space zone. An upper space is disposed above the partition wall and configured to allow lubricating oil scooped up from the first space zone by a ring gear to flow in the second space zone. A flow-out path is disposed below the upper space and configured to allow the lubricating oil to flow out of the second space zone to the first space zone.

  • Patent number: 12135075
    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.
