    摘要： A semicrawler-type working vehicle is provided having a vehicle body (3), a front steering control wheel (7) arranged at a front side of the vehicle body, a drive shaft (26) and a pivot shaft (22) arranged at a rear side of the vehicle body, and a semicrawler unit (2) driven by the drive shaft. The semicrawler-type working vehicle comprises: a track frame (16) by which the semicrawler unit (2) is supported via the pivot shaft (22) so as to be pivotable relative to the vehicle body (3); a drive wheel (11) arranged on the drive shaft (26); a front driven wheel (12) and a rear driven wheel (13) that are supported by the track frame (16) such that a horizontal distance from the drive wheel (11) to the front driven wheel (12) is longer than a horizontal distance from the drive wheel (11) to the rear driven wheel (13); and a crawler belt (15) that is wound around the drive wheel (11), the front driven wheel (12), and the rear driven wheel (13). The pivot shaft (22) is displaced forward than a vertical line that runs through a center of the drive wheel (11).

    摘要： A crawler traveling apparatus includes a rubber crawler belt having a plurality of driving projections formed with a predetermined peripheral pitch on an inner peripheral face of the belt, a drive wheel rotatable when engaged with the driving projections of the crawler belt for driving the belt, and a plurality of free wheels rotatable for laterally guiding the driving projections under movement. Each driving projection has an upper half having a lateral face including an upper half lateral face portion and a lower half having a lower half lateral face portion, the upper half lateral face portion having an erect inclination angle smaller than an erect inclination angle of the lower half lateral face portion. Each free wheel has an inner lateral face opposed to the driving projection, the inner lateral face having an inclined guide face having an inclination parallel to the lower half lateral face portion of the driving projection. The inclined guide face has a height L3 shorter than a height L1 of the lower half lateral face portion when an inner peripheral face of the crawler belt is placed under proper contact with an outer peripheral face of the free wheel.

    摘要： A power steering apparatus comprising steering arms for steering front wheels of a vehicle mounted at opposite ends of an axle, and a power cylinder extending parallel to the axle for driving the steering arms. The axle is oscillatably supported by an axle frame through a center shaft. The power cylinder is connected to the axle by a connecting device to be movable in three-dimensional directions. The connecting device includes a support shaft extending parrallel to the axle, an oscillatable arm connected to the support shaft, and a universal joint for interconnecting the oscillatable member and the cylinder. The universal joint has an axis extending perpendicular to the center axis.
