摘要： PROBLEM TO BE SOLVED: To provide a turning-run device of a working vehicle capable of making a turn in an excellent condition when the condition in which a straight drive is commanded is changed to the condition in which a right turn or a left turn is commanded by a turn command means if speed increase or decrease is commanded by a speed change operating tool. SOLUTION: The output synchronized drive is realized in which the speed change output of a continuously variable transmission 8 for turning is the same or substantially the same as the speed change output of a continuously variable transmission 7 for straight drive. When the speed increase is commanded, the speed change operational condition displaced to the high-speed side of the set value than the speed change operational condition corresponding to the same speed change output as the speed change output of the continuously variable transmission 7 for straight drive is set as a target speed change operational condition. When the speed decrease is commanded, the speed change operational condition displaced to the low-speed side of the set value than the speed change operational condition corresponding to the same speed change output as the speed change output of the continuously variable transmission 7 for straight drive is set as a target speed change operational condition.

摘要： PROBLEM TO BE SOLVED: To provide a running control device of a working vehicle capable of increasing a turning performance in turning. SOLUTION: This running control device of the working vehicle comprises a pair of continuously variable transmissions 11R and 11L for steplessly gear-shifting a pair of right and left running devices, a gear-shift operation means 30 capable of gear-shifting the pair of continuously variable transmissions, and a control means 31 performing the running control. When turning is instructed by a turning instruction means, a target rotational speed is provided so that the speed ratio of the pair of right and left continuously variable transmissions 11R and 11L becomes a speed ratio corresponding to an instructed turning radius and a controlled dead zone is determined so that the range of the dead band is narrower as the target rotational speed is lowered to operate the gear-shift operation means 30 so that the output rotational speed of the continuously variable transmission on the turning center side is stored in the controlled dead zone for the target rotational speed.

摘要： PROBLEM TO BE SOLVED: To provide a turning control apparatus for a working vehicle enabling small turning with a small turning radius without a widened range of moving operation and specifically gentle turning with fine adjustment and eliminating disadvantages such as shocks to a car body caused by abrupt change in a running state of a running device.

The relation between a moving amount of a turning lever 26 from a straight-forward command position and a turning radius is determined in correspondence to a quadratic function to enlarge the turning radius as the moving amount widens and to change to the larger side a variation amount of the turning radius per a unit amount of the moving amount over a whole range. An operation mechanism 30 for running is actuated to attain a target turning radius obtained based on an operational position of the turning lever 26 and the relation with the secondary function.
