SPEED CHANGE CONTROL APPARATUS FOR WORK VEHICLE |
摘要 |
A speed change control apparatus (30) for a work vehicle (1) includes a hydraulic continuously variable speed transmission (8) that performs speed change on power input from an engine (7) by changing a trunnion shaft angle based on a depressing amount of a speed change pedal (22) and outputs the power, a pedal position detector (321) that detects a pedal position responsive to the depressing amount of the speed change pedal (22), and a control unit (32) that controls a number of revolutions of the engine (7) and the trunnion shaft angle of the hydraulic continuously variable speed transmission (8) based on a detection value of the pedal position detector (321). The control unit (32) performs control so that the trunnion shaft angle is maximized at a second pedal position (P2) set to a position shallower than a first pedal position (P1) at which the number of revolutions of the engine (7) is maximized by a depressing operation of the speed change pedal (22). |
