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.

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.

In a transmission apparatus for a saddle-type vehicle, dowels on first transmission gears are engageable in and disengageable from dowel holes in adjacent second transmission gears to shift gear positions. The first transmission gears are slidable in response to angular movement of a shift spindle caused by operating a shift pedal. Invalid engagement time, during which the dowels and dowel columns are in sliding abutment, at an idling engine rotational speed is in the range from 0 msec. to 40 msec., providing an enhanced feeling for gear shifting operations and reduce hammering noise.v

A method for shifting between a low speed range and a high speed range for a two-speed transfer case in a four-wheel drive vehicle includes determining a target transmission gear ratio and a desired transfer case range based on the current vehicle speed and the initial transfer case range. The transmission is shifted to the target transmission gear ratio when it is determined that the vehicle speed is in an appropriate range. The transfer case input torque is reduced to a minimum value, and the transfer case is shifted to neutral. The method further includes adjusting the engine speed and transmission gear setting to control the transmission output shaft speed to a desired range. The transfer case is shifted from neutral to the desired transfer case range when the transmission output shaft speed is within the desired range of transmission output shaft speed.

A drive switching apparatus includes an output member connected to a drive switching member and displacing the drive switching member to three shift positions by being rotated, a deceleration mechanism decelerating rotation of an input portion connected to an electric motor and outputting the rotation to an output portion, a rotation absorption mechanism including an elastic member interposed between an input element connected to the output portion and an output element connected to the output member, the rotation absorption mechanism absorbing rotation of the input element in a case where rotation of the output element is restricted during the rotation of the input element, aid a switch operation portion provided at the output element, the switch operation portion turning a switch on and off according to a rotational position of the output member in order to detect the shift positions of the drive switching member.

A shifting device for a dual clutch transmission as a speed-change transmission for motor vehicles, including two coaxially arranged input shafts, each being activatable via a clutch, an axially parallel output shaft and gearwheel sets that are mounted on the shafts and can be shifted by means of shifting clutches to allow a plurality of forward gears and a reverse gear, the gearwheel sets being subdivided into a sub-transmission having the one input shaft and a sub-transmission having the other input shaft. To achieve a wider gear-ratio spread in a structurally compact construction, a planetary gear train that can be shifted between two gear ratio stages is mounted upstream of the sub-transmission having the hollow input shaft.

A transfer includes: an input shaft; an output shaft; a high-low switching mechanism; an output member whose output destination is different from output destination of the output shaft; a clutch for transmitting a power to the output member; a first transmitting mechanism for transmitting movement of an internally threaded member to the clutch; and a drum cam having a cam groove. The cam groove includes a first inclined section that causes the high-low switching mechanism to be switched between a high-speed gear stage and a low-speed gear stage, and a second inclined section that causes the first transmitting mechanism to be switched between (i) a separated position in which the first transmitting mechanism is separated from the clutch and (ii) a contact position in which the first transmitting mechanism is in contact with the clutch, while the high-speed gear stage is established in the high-low switching mechanism.

A change-speed transmission for motor vehicles, in particular manual transmission, having a plurality of forward gears and, optionally, one reverse gear, includes at least one input shaft, an output shaft and, optionally, a layshaft, between which the idler gears, which can be shifted via synchronous clutches, and the fixed gears of the gearwheel sets are arranged. At least one of the has a two-part design and is mounted in the transmission housing with mutually different axes of rotation, an annular gear stage is functionally provided between the sub-shafts and includes a internally-toothed annular gear and an externally-toothed spur gear that meshes therewith, the sub-shaft which has the larger axial distance to the other shaft bearing gearwheels of the lower forward gears and, optionally, of the reverse gear.
