    • The present invention is to deter or prevent bucking of a wheeled work vehicle if the wheeled work vehicle currently in a traveling operation-only state shifts into a combination operation state. A traveling control device for a wheeled work vehicle includes a valve control member (120; 162) for controlling a flow control valve (161) in correspondence to the traveling operation quantity detected by a traveling operation quantity detection member (171), the work operation quantity detected by a work operation quantity detection member (172) and the output pressure of a hydraulic pump (130) detected by an output pressure detection member (173). The valve control member (120; 162) controls the flow rate of pressure oil delivered to a traveling motor (115) so as to deter bucking of the wheeled work vehicle if the wheeled work vehicle, currently in a traveling operation-only state in which a traveling operation member (155) is operated but the work operation member (156; 157) is not operated, shifts into a combination operation state in which the traveling operation member (155) is operated and the work operation member (156; 157) is also operated.
    • 本发明是为了阻止或者防止轮式作业车辆当前处于行驶中的状态转变为组合运转状态时的起落架作用。 用于轮式作业车辆的行驶控制装置包括:用于根据由行驶操作量检测构件(171)检测的行驶操作量控制流量控制阀(161)的阀控制构件(120; 162),工作操作 由工作操作量检测构件(172)检测的量和由输出压力检测构件(173)检测的液压泵(130)的输出压力。 阀控制构件(120; 162)控制输送到行驶马达(115)的压力油的流量,以便如果轮式作业车辆目前处于仅行驶的行驶状态,则阻止轮式作业车辆的弯曲 行驶操作构件155被操作而工作操作构件(156; 157)未被操作,转移到行驶操作构件155被操作的组合操作状态和工作操作构件156; 157) 也经营。
