摘要： An axle driving apparatus which is so constructed that an input pulley for engine power is set lower in mounting position with respect to the axis of a driving axle so as to enable the platform of a vehicle to be lowered. The engine position lowers to promote miniaturization, a lower center of gravity and running stability of the vehicle. For maintenance of the transmission for driving the axle, the entire axle driving apparatus need not be removed from the frame of the vehicle. A bearing for supporting the axle to the casing is held with exact dimensional precision so as not to cause a backlash on the axle, to thereby prolong the life span of the bearing. The axle is ensured to be sealed, the number of mounting bolts for the casing need not be increased in order to improve rigidity, and the casing is strong so that the assembly time for the axle driving apparatus is minimized.

摘要： A vehicle power transmission for tractors and the like having a fluid operated speed-change mechanism which comprises a plurality of rotatably mounted speed-change gears arranged on a lay shaft and a plurality of fluid actuated clutches associated with the respective speed-change gears for selectively connecting each of the gears to the lay shaft. A brake is provided which selectively brakes the lay shaft at the non-operation state of the fluid operated speed-change mechanism. The brake prevents unexpected transmission of power through the speed-change mechanism at the non-operation state of the mechanism, thereby preventing problems such as an unexpected start of the vehicle.

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 transmission shaft (62) mounting thereon fluid-operated clutch means (68) which discontinues selectively the input of power to such shaft is enclosed at one end portion thereof by a hollow cylinder (86) projected inwardly from an inner wall surface of transmission case (28) for power transmission. An annular groove (89) formed to said one end portion of shaft (62) at the outer peripheral surface thereof and communicated to the clutch means (68) via fluid path (85) in the shaft (62) is sealed by the hollow cylinder (86) so as to form an annular fluid chamber (90) which constitutes a rotary joint portion of fluid conduit line for the clutch means (68). Braking mechanism of a brake (69) associated with the clutch means (69) for braking the shaft (62) in the non-operated state of clutch is arranged within the hollow cylinder (86) by employing such cylinder as brake case. The rotary joint portion and brake (69) are thus arranged within transmission case (28) without a need of structure arranged outside the case (28).
