摘要： A drive assembly has a track frame, an idler, and a sprocket arranged substantially on a straight line that includes single track roller units disposed respectively closest to the idler and closest to the sprocket. The single track roller units each rotatably support a track roller at an end of an arm that is rockably attached at another end to the track frame. The single track roller units bear the vehicle body load at the distal end of the arm through elastic members. A double track roller unit is interposed between the single track roller units, and includes a first arm rockably attached at its end to the track frame and a second arm rockably attached at its central portion to another end of the first arm. The second arm rotatably supports paired front and rear track rollers at two ends thereof.

摘要： In an apparatus for controlling the vertical movement of a scraper blade (18) of a bulldozer, a four-position hydraulic control valve (12), having HOLD, UP, DOWN, and FLOAT positions, maintains the scraper blade in the FLOAT condition without requiring a detent mechanism, even when the three-position operation lever (1, 51) is released with the hydraulic control valve (12) in the FLOAT position. The operation lever (1, 51), having HOLD, UP, and DOWN positions, provides electrical signals to a controller (4) for actuating the hydraulic control valve (12) with pilot pressures provided via solenoid pilot valves (6, 7). A hydraulic cylinder (19), connected to the scraper blade (18), is actuated by hydraulic oil from the hydraulic control valve (12). A control device (2, 52), for generating an electrical signal for the FLOAT position and transmitting that electrical signal to the controller (4), is provided on the three-position operation lever (1, 51), so that the hydraulic control valve (12) is held at the FLOAT position in response to the electrical signal from the control device (2, 52).
