The invention discloses an automatic opening and closing mechanism for a crawler wheel cabin of an amphibious vehicle. The automatic opening and closing mechanism comprises a cover plate, a connecting rod I, a connecting rod II, a second support, a third support and a hinge, one end of the connecting rod I is hinged with one end of the connecting rod II; the second support is matched with the dovetail groove of the third support, and the second support can slide; the third support is fixed on the cover plate; and the upper end of the cover plate is hinged with the vehicle body through a hinge. Executing mechanisms such as a swing cylinder are not added, the connecting rod, the sliding block and the turnover mechanism are ingeniously designed, the rotating motion of the balance elbow of the crawler wheel lifting mechanism is converted into the rotating motion of the orthogonal plane cover plate, the structure is simple, and the cost is low; and the automatic opening and closing function of the crawler wheel cabins can be achieved, the weight of the system is reduced, and the water navigational speed of the amphibious vehicle is increased.
本发明公开了一种两栖车辆履带轮舱自动开合机构,包括盖板、连杆I、连杆Ⅱ、第二支座、第三支座及合页;连杆I一端与连杆Ⅱ的一端铰接,连杆I另一端与第二支座铰接;第二支座与第三支座的燕尾槽配合,第二支座能够滑动;第三支座固定在盖板上;所述的盖板上端通过合页与车体铰接。本发明不增加摆动缸等执行机构,巧妙的设计连杆、滑块、翻转机构,将履带轮抬升机构平衡肘的旋转运动转换为正交平面盖板的旋转运动,结构简单,成本低;而且能够实现履带轮舱的自动开合功能,又减轻了系统的重量,提高了两栖车辆水上航速。
