The invention discloses a crawler belt self-adaptive tensioning mechanism suitable for a crawler belt type forest fire fighting truck, which comprises a frame, a crawler belt, a guide wheel, a thrust wheel, a riding wheel, a driving wheel, a first transmission rod, a second transmission rod, a third transmission rod, a spring guide rod, a tensioning spring, a hinge block, a first base, a second base and a third base, the crawler belt is arranged on the outer sides of the guide wheel, the thrust wheel, the riding wheel and the driving wheel, the guide wheel and the thrust wheel are connected in motion through a first transmission rod, a second transmission rod, a hinge block, a third transmission rod, a tensioning spring and a spring guide rod, and the first transmission rod, the second transmission rod and the spring guide rod are connected with the frame through a first base, a second base and a third base respectively. When the tensioning spring senses the pressure transmitted by the thrust wheel through the third transmission rod and the spring guide rod, the guide wheel is pushed to move clockwise with the third base as the axis through the spring guide rod, the third transmission rod, the hinge block, the second transmission rod and the first transmission rod, and the crawler belt is tensioned. Therefore, the purpose of self-adaptive tensioning of the crawler belt of the crawler-type forest fire fighting truck is achieved.

    本发明公开了一种适用于履带式森林消防车的履带自适应张紧机构,包括车架、履带、导向轮、支重轮、托轮、驱动轮、第一传动杆、第二传动杆、第三传动杆、弹簧导向杆、张紧弹簧、铰链块、第一底座、第二底座、第三底座,履带设在导向轮、支重轮、托轮、驱动轮的外侧,通过第一传动杆、第二传动杆、铰链块、第三传动杆、张紧弹簧、弹簧导向杆将导向轮与支重轮的运动相连,第一传动杆、第二传动杆、弹簧导向杆分别通过第一底座、第二底座、第三底座与车架连接。张紧弹簧感知到支重轮通过第三传动杆、弹簧导向杆传递的压力便通过弹簧导向杆、第三传动杆、铰链块、第二传动杆、第一传动杆推动导向轮以第三底座为轴心顺时针运动,履带得以张紧,进而达到履带式森林消防车的履带自适应张紧的目的。
