摘要： A crawler-type vehicle undercarriage including a track frame, an idler, a sprocket, a crawler encompassing the idler, track rollers, and the sprocket and the idler, the sprocket and the track frame located to line up in a straight line comprising the crawler-type vehicle undercarriage comprising (i) an idler avoided from pivoting upwardly or downwardly relative to the track frame, (ii) a first arm pivotally mounted at the bottom of the track frame, and (iii) a second arm pivotally connected to end portion of the first arm. The track roller unit adjacent the sprocket is preferably pivoted about a pivot center of the first arm positioned at the bottom of the track frame and toward the idler relative to a pivot center of the second arm. The track roller travel improves a flexibility of the track roller to the crawler, and work in a high tractive force is carried out with the track rollers providing unchangeable real contact areas to the ground.

摘要： The present invention provides a track frame connecting structure of a heavy work vehicle that can minimize the amount of up and down movement of the ends of an equalizer bar, so as to make track frames have a sufficiently wide range of straight-line motion for a heavy work vehicle like a tractor. In the track frame connecting structure of a working vehicle in which an equalizer bar which is pivotally mounted on a body is connected to connecting links, the connecting links and the track frames are connected with each other, the connecting links and limiting links are connected with each other, and the links and the body are connected with each other. In addition, the ratio of the distance between an axis S1 of the connecting link 110 and an axis L of the limiting links 120 to the distance between an axis P1 of the equalizer bar 3a and an axis K of the center pin 2 is set substantially equal to the ratio of the distance between an axis Q1 of the connecting link 110 and the axis P1 of the equalizer bar 3a to the distance between the axis of the connecting link Q1 and the axis S1 of the connecting link. The axes Q1, P1, S1 are arranged on a straight line, and the straight line which connects the axes Q1, P1, S1 is set substantially parallel to a body vertical center XX of the body.

摘要： A bulldozer includes a cab and an engine hood. The cab has a foremost surface, and left and right front surfaces. The engine hood has an upper surface, left and right side surfaces, and flat first, second and third inclined surfaces. The first and second inclined surfaces contact the rear side of the upper surface and rear sides of the left and right side surfaces, and are inclined more obliquely to the right rear and left rear than the left and right side surfaces, respectively. The first, second and third inclined surfaces are inclined to face downward to the rear. The third inclined surface contacts the first and second inclined surfaces, and the upper surface. A window attached to the foremost surface is arranged in a vertical direction above first and second sides closest to the foremost surface out of sides constituting the first and second inclined surfaces, respectively.
