  • Patent number: 7225704
    Abstract: In a transmission for a working vehicle, a working unit includes a hydraulic power unit and a valve unit enclosed in a first bulging portion of a transmission case closer to an upper side or on a top surface thereof and connected with each other along a vehicle lengthwise direction. The first bulging portion is closer to a first lateral side along the vehicle width direction of the transmission case, while a hydraulic pump is located closer to a second lateral side. Hydraulic fluid is drawn from the transmission case, around a lower side of the hydraulic pump, through a suction port thereof, and discharged to a suction port of the valve unit. The hydraulic power unit includes a cylinder tube and piston, extending in the lengthwise direction, and a support shaft, extending along the width direction, which is supported by the transmission case and connected to a lift arm.

  • Patent number: 7047839
    Abstract: In a transmission for a working vehicle, a PTO input shaft is located with its rotational axis extending in a vehicle lengthwise direction substantially at a widthwise center of a transmission case along a vehicle width direction. A running power input shaft is located with its rotational axis extending in the vehicle lengthwise direction substantially at the same position as that of the PTO input shaft along the vehicle width direction and at a lower side of the PTO input shaft. The transmission case provides an accommodation space for accommodating a differential gear unit, which space is displaced to a first lateral side of the vehicle along the vehicle width direction. A running power transmission shaft is located on the front side of the space with its axis extending in the vehicle lengthwise direction, and the running power input shaft, the running power transmission shaft and the differential gear unit are interlocked to each other via a running power gear train.

  • Publication number: 20050246867
    Abstract: A tightening band used for fixing, for example, a cover for protecting a joint of a rotary shaft of an automobile, and a method for producing the same. The tightening band realizes an improved workability of attachment, a proper tightening strength, a wider applicable range of members to be tightened, and a stable tightening strength lasting for a long time. In the tightening band, a pattern of projections and depressions is formed on the surface of each component. Preferably, the pattern is formed by providing depressions, each having a depth of 2 ?m to 30 ?m, on the surface of a band main body, a lever plate, and a lever-plate fixing member.

  • Patent number: 6681878
    Abstract: In an axle assembly, a differential gear device includes a ring gear and a differential cage. The ring gear has a gear portion formed on a first side surface thereof, which first side surface faces the input shaft and is positioned along the axis of the driving axles, for being operatively connected with the input shaft, and forms an axle hole through which an inner end of one of the right and left driving axles relatively rotatably passes. The differential cage is relatively non-rotatably connected with the ring gear via a second side surface of the ring gear, which second side surface faces away from the input shaft and is positioned along the axis of the driving axles. The differential case also forms therein an axle hole through which an inner end of the residual one of the right and left driving axles relatively rotatably passes, so that the inner ends of the right and left driving axles face to each other.

  • Patent number: 6564891
    Abstract: A power take-off casing (47) including therein a rear-PTO shaft (12) and a transmission mechanism (50) therefor is mounted on an outer surface of a rear wall (3c) of the transmission casing (3) disposed between left and right rear wheels (4) which constitute drive wheels for a working vehicle, and a gear (52) constituting an input member of the transmission mechanism is operatively connected to a drive mechanism (46) for a mid-PTO shaft (9) which extends forwardly from the inside of transmission casing through a front wall (3a) thereof. A clutch (60) for selectively cutting-off the drive of the rear-PTO shaft is provided preferably such that it couples the gear selectively to a drive gear (58) which is rotatably mounted on the mid-PTO shaft. In a working vehicle in which a transmission casing is disposed between left and right front wheels constituting the drive wheels for the vehicle, a power take-off casing having a front-PTO shaft is mounted on an outer surface of a front wall of the transmission casing.
