摘要： PROBLEM TO BE SOLVED: To facilitate HST running gear operations. SOLUTION: Each of slide bodies 27, 30 is structured such that either of them performs sliding operation linked with a sliding motion of the slide operating body. Both slide bodies are rotatable integrally with a transmission shaft 34. Each slide body oscillatably axially supports the intermediate portion of each guide body extending in the width direction. Linked with the rotational motion of each slide body, the position of each slide body is variable through oscillation. Each guide body is engaged with one side portion of an arm extending in the lateral direction with the intermediate portion oscillatably axially supported, such that it is slidable in the longitudinal direction of each guide member, while the other side portion of each arm is connected in a linked condition to each running drive adjustment member. Both slide bodies are provided with return spring for neutral state which urges both slide bodies to the neutral condition and a neutral position stopper 33 that stops both slide members which have been urged to the neutral state by the return spring at a neutral position.

摘要： PURPOSE:To enhance operability and smooth driving operation by forming constitution in which a pair of speed change shafts are rotated and at the same time a pair of sliding bodies are integrally rotated and the travelling parts of the right and left sides are operated for speed increase by operating respective HST speed increase/ decrease mechanisms so as to advance when a speed change operation tool is operated to the advance side in order to make a vehicle body advancing travel. CONSTITUTION:When a main speed change lever 35 is operated for speed change to an advance side speed change position, the main speed change shafts 34, 34 of the tight and left sides are integrally rotated through a link 36b and the like, and respective swash plates for controlling the respective hydraulic motors M1, M2 of the right and left sides through front and back arms 43, 73, front and back links 44, 74, front and back guide bodies 42, 72, front and back rotors 47, 77, connecting wires 55, 85 and the like are brought into an identical tilt angle, so that a vehicle body advances straight. In that state, when a steering wheel 18 is turned, for instance, to the right, a front slide operating body 25b mounted on a rack 24 which is engaged with a pinion gear 23 pushes the front guide body 42 to the right side to slide it, and the swash plate of the hydraulic motor M1 of the right side is made to approach a neutral position, so that a vehicle body is gently turned to the right.

摘要： PURPOSE:To prevent operation errors by enabling straight travel operation, left and right turning operation, and left and right abrupt turning operation by turning operation tool regardless of shift operation position of a shift lever for executing advancing/retreating shift of a vehicle body in a work vehicle provided with left and right independent travel drive mechanisms. CONSTITUTION:When a main shift lever 36 is operated to, for example, an advance side shift position, the main shift shaft 34 moves rotationally, left and right guides 42, 72 move rotationally via left and right slide bodies 27, 30 left and right swinging arms 43 left and right links 44, 84, and left and right rotor support arms 48, 78 are tiltedly moved via left and right rotors 47, 77. Then left and right inclined boards 84 for controlling a hydraulic motor become sane inclined angle so that left and right side travel parts are forwardly driven at the same speed. On the other hand, for example, a turning operation tool is right-turning operated from straight travel state so as to move a pinion shaft rotationally and when the rack engaged thereto is moved in the left direction, the left slide body 27 is turned left. Thereby, right travel part becomes in decelerated or stop conditions so as to make the machine body turn right.
