The invention discloses an expansion transmission mechanism for an expansion cabin of a square cabin vehicle, and relates to the technical field of expansion cabins of square cabin vehicles. The device comprises an expansion cabin, and a transmission case and a torque increasing gearbox which are fixedly connected with the expansion cabin, wherein a first transmission shaft is rotationally connected between two end parts in the transmission case; a second transmission shaft is rotationally connected between the transmission box and the torque increasing gearbox; a first duplicate gear is rotationally connected between the two ends in the torque increasing gearbox. A third transmission shaft is rotationally connected between the two ends in the torque increasing gearbox. The third transmission shaft is in engaged transmission with a load rack through a load gear; and the load rack is fixedly connected with the expansion cabin. Through cooperative use of the torque increasing gearbox, the second transmission shaft, the first duplicate gear, the third transmission shaft and the load rack, when the second transmission shaft rotates, after torque increasing transmission is conducted through the first transmission gear, the first duplicate gear and the second transmission gear, the load gear can obtain large torque, and therefore the purpose of opening and closing the heavy-load expansion cabin is achieved.

    本发明公开了一种方舱车扩展舱用扩展传动机构,涉及方舱车扩展舱技术领域。本发明包括拓展舱和与扩展舱固定连接的传动箱和增扭变速箱,传动箱内两端部之间转动连接有第一传动轴;传动箱与增扭变速箱之间转动连接有第二传动轴;增扭变速箱内两端之间转动连接有第一双联齿轮;增扭变速箱内两端之间转动连接有第三传动轴;第三传动轴通过负载齿轮啮合传动有负载齿条;负载齿条与扩展舱相互固定连接。本发明通过增扭变速箱、第二传动轴、第一双联齿轮、第三传动轴、和负载齿条的配合使用,第二传动轴转动时,经第一传动齿轮、第一双联齿轮和第二传动齿轮增扭传动后,可以让负载齿轮获得较大的扭矩,从而达到启闭重载扩展舱的目的。
