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.

A coolant pump assembly having a combined hydraulic drive pump and a coolant circulating pump is disclosed herein, for use in connection with a utility vehicle, such as a ride-on or stand-on mower. Such a vehicle includes at least one combination pump assembly that utilizes a first fluid circuit to hydraulically drive a wheel of the vehicle and a second fluid circuit to cool one or more vehicle components.

A work machine includes a transmission case (5) extending in the front-back direction of a machine body, a first hydraulic unit (V) provided on one of mutually opposite wall portions (5a, 5b) of the transmission case (5), a second hydraulic unit (44) provided on a second one of the wall portions (5a, 5b), and a supply passage (43) configured to supply operating oil from the first hydraulic unit (V) to the second hydraulic unit (44). The first hydraulic unit (V) and the second hydraulic unit (44) are aligned to be overlapped with each other as viewed in a direction orthogonal to a case axis (X) extending along the front-back direction of the transmission case (5). The supply passage (43) extends inside the transmission case (5) in a straight line orthogonal to the case axis (X).

Some embodiments of a gearbox for an irrigation system can comprise a housing, a worm gear within the housing, a bull gear within the housing and configured to be engaged with the worm gear, a diaphragm, and a vent. The diaphragm can define a chamber configured for expansion and contraction and configured to be positioned inside the housing to relieve pressure build-up within the housing. The vent can be configured to allow air to flow between the atmosphere and the chamber.

There is provided a tractor with an improved clutch housing structure, which includes a hydro-static transmission (HST) positioned between a clutch and a secondary transmission, to transmit power. The tractor comprises: a clutch housing with the clutch and the HST positioned inside; a partition to separate the clutch from the HST formed inside the clutch housing; and a heat-radiating opening formed in the partition.

The present invention relates to an exchangeable milling drum box for a ground milling machine, particularly for a road milling machine, a recycler, a stabilizer or a surface miner, with a milling drum rotatably mounted in the exchangeable milling drum box and a transmission, via which the milling drum can be driven, the transmission comprising a lubrication device with a lubricant, and the exchangeable milling drum box comprising a cooling and/or heating device for lubricant. Furthermore, the present invention relates to a ground milling machine having such an exchangeable milling drum box. The present invention also relates to a method for cooling and/or heating lubricant of a transmission of a milling drum mounted rotatably in an exchangeable milling drum box of a ground milling machine, the method comprising the steps: Supplying cooling and/or a heating medium from the ground milling machine to the lubricant located in a lubrication device arranged on the exchangeable milling drum box; cooling and/or heating the lubricant through heat transfer between the coolant and/or heating medium and the lubricant; and discharging the cooling and/or heating medium from the exchangeable milling drum box to the ground milling machine.

A work vehicle according to the present invention includes an engine installed in a traveling machine body supported by traveling units, and a transmission case incorporating a hydraulic continuously variable transmission. The transmission case incorporates a forward/backward traveling switching mechanism. The work vehicle includes forward traveling valves for forward traveling hydraulic clutches, a backward traveling valve for a backward traveling hydraulic clutch, and a master valve configured to control hydraulic oil supplying to the forward traveling valves and the backward traveling valve. A part of a hydraulic circuit is formed on a front lid member of the transmission case. The forward traveling valves, the backward traveling valve, and the master valve are attached on a front surface side of the front lid member.

An axle assembly for a landfill compactor includes an axle housing, a carrier housing located proximate the center of the axle housing, a drain plug located on an underside of the carrier housing, and a guard. The guard is attached to the underside of the carrier housing with adhesive such that the guard covers the drain plug and is configured to protect and give access to the drain.

A transfer case for a utility terrain vehicle includes a housing. An input gear is rotatably coupled to the housing on a first rotational axis. An idler gear assembly is rotatably coupled to the housing on a second rotational axis offset from the first rotational axis. The idler gear assembly includes a major idler gear engaged with the input gear and a minor idler gear. An output gear assembly including an output shaft and an output gear is rotatably coupled to the housing on a third rotational axis offset from the second rotational axis. The output gear is engaged with the minor idler gear of the idler gear assembly.

A transmission housing (1) comprising a shaft (2) housed at least partially inside the housing (1) and, mounted on said shaft (2), at least one rotary element (3) and a rolling bearing (4), the rolling bearing (4) comprising an inner ring (5) and an outer ring (6) that are coaxial, separated from each other by rolling members (7). The housing (1) further comprises a blind or through tubular body (8) mounted on the shaft (2) and interposed at least partially between the shaft (2) and the rotary element (3), the rotary element (3) being mounted rotatably secured to the tubular body (8), and the tubular body (8) being kept rotatably secured to the shaft (2) by the inner ring (5), referred to as the constriction ring, of the rolling bearing (4), force-fitted onto said tubular body (8).
