    • A transmission device for a work vehicle, comprising a travel drive system for transmitting engine power to a travel device; an implement drive system for transmitting engine power to an external power take-off shaft; braking operation tools for a braking operation; a stop operation mechanism provided to the travel drive system and capable of interrupting the transmission of power to the travel device; and a hydraulically operated PTO clutch for interrupting the transmission of power to the external power take-off shaft, the PTO shaft being provided to the implement drive system; wherein the stop operation mechanism and the PTO clutch are linked with the braking operation tools so that the stop operation mechanism is operated to a power transmission stopping position and the PTO clutch is disengaged along with a pressing operation of the braking operation tools, and the PTO clutch is engaged along with a press-releasing operation of the braking operation tools; and an operation timing is set so that the PTO clutch is disengaged after traveling is detected to have stopped when the braking operation tools are operated in the pressing direction, and that the PTO clutch is engaged before traveling is started when the braking operation tools are operated in the press-releasing direction.
    • 一种用于工作车辆的传动装置,包括用于将发动机功率传递给行驶装置的行驶驱动系统; 用于将发动机功率传递到外部动力输出轴的工具驱动系统; 用于制动操作的制动操作工具; 停止操作机构,其设置在所述行驶驱动系统上并且能够中断向行驶装置传递动力; 以及液压操作的PTO离合器,用于中断向外部动力输出轴的动力传递,PTO轴被提供到工具驱动系统; 其中,停止操作机构和PTO离合器与制动操作工具连接,使得停止操作机构被操作到动力传递停止位置,并且PTO离合器与制动操作工具的按压操作一起分离,并且PTO 离合器与制动操作工具的压力释放操作一起接合; 并且设定操作定时,使得当制动操作工具沿按压方向被操作时检测到行驶被停止之后,PTO离合器脱离,并且当行驶时PTO离合器接合,当制动操作工具被操作时开始 在压力释放方向。
