摘要： In a vehicle multi-ratio transmission comprising a plurality of change-speed gear trains, including a backward directional gear train, with which synchronizer clutches are associated for actuating same, two multidisc-type synchronizer clutches (12) are employed for actuating one of forward directional gear trains, which is operated under a heavy condition, and for actuating the backward directional gear train. Cone-type synchronizer clutches (11) are employed for actuating the other gear trains. Seizing of clutch members as well as an unexpected start of the vehicle at a neutral condition of the transmission are well prevented and increase of cost for securing these advantages is suppressed.

摘要： An additional speed change mechanism (11) is incorporated in a vehicle-driving power transmission path of a tractor. The change mechanism is disposed within a main clutch housing (1) using axially spaced front and rear bearing support frames (6, 7) as supports for transmission shafts (9, 10, 11) associated to the mechanism. The front frame is fixedly mounted on a front surface of an internal flange (5) on the housing and may also be used as a support for preassembling the mechanism at the outside of clutch housing. The rear frame is fixedly mounted on a front surface of rear wall (1a) of the housing and may be varied in configuration in accordance with a given design of the change mechanism. An adaptability to various designs of the change mechanism is given while assuring an easy assemblage of the change mechanism into the clutch housing.

摘要： An axle driving apparatus for a small-sized vehicle, such as a tractor, which divides its axle casing into first and second axle casings. A hydraulic pump, provided with a vertical pump shaft, is disposed within one of the axle casings. A hydraulic motor, provided with a horizontal motor shaft; a speed reduction shaft; and a differential gear unit, are disposed within the other of said axle casings. This configuration allows a driving force to be transmitted from the vertical pump shaft to the horizontal motor shaft.

摘要： A front and rear transmission casing are joined to form a single casing. Upper and lower input shafts are received and supported by the front casing. The lower input shaft drives a change speed gearing with a speed change shaft and a pinion shaft. The pinion shaft has a pinion gear located on a further end of the shaft and engages a ring gear of a differential. The upper input shaft drives a clutch driven shaft through a PTO clutch unit. A rear PTO shaft is driven by the clutch driven shaft and extends out of the rear casing. A mid PTO shaft is also driven by the clutch driven shaft and extends out of the front casing.

摘要： A hydraulic driving apparatus for a wheeled vehicle including a prime mover and a pair of wheels comprises a stepless transmission mechanism for traveling which transmits driving force from the prime mover to the drive wheels so as rotate the drive wheels in a common forward or rearward direction, and a steering transmission mechanism including a hydrostatic stepless transmission including a variable hydraulic pump and a hydraulic motor fluidly connected to each other, wherein a rotational force of the hydraulic motor is divided into opposite directive rotations transmitted to the respective drive wheels. A switching valve is disposed between the variable hydraulic pump and the hydraulic motor in the steering transmission mechanism. The switching valve reverses the rotational direction of the motor relative to the discharge direction from the pump according to a change in the traveling direction of the vehicle between forward and rearward, and divides a pair of oil passages between the pump and the motor into independent circuits which include the pump and the motor, respectively.
