An undercarriage EHA turning shimmy damping device relates to the field of servo mechanisms and comprises a valve group module, a transmission assembly, a piston rod, a cylinder barrel and a driving device. The two cylinder barrels are connected to the two ends of the valve bank module, the two ends of the piston rod are inserted into inner holes of the cylinder barrels on the left side and the right side, the piston rod and the cylinder barrels are sealed and slidably connected, and a driving cavity is formed between the piston rod and the cylinder barrels. The driving device drives the piston rod to linearly move in the axis direction of the cylinder barrel by controlling the flow and the direction of oil entering the two driving cavities. The transmission assembly comprises a rotating shaft and a rocker, the rotating shaft is rotationally connected to the valve group module, the piston rod moves to drive the rotating shaft to rotate, the rotating shaft is connected with a connecting arm, one end of the rocker is rotationally connected to the connecting arm, the valve group module is fixedly connected to the main supporting column, and the end of the rocker is connected to the rotating sleeve. Linear motion of the piston rod is converted into rotary motion through the transmission assembly, and the installation space is saved; and the driving controller and the executing mechanism are integrally designed, so that the device is more compact in structure and lighter in weight.

    一种起落架EHA转弯减摆装置,涉及伺服机构领域,装置包括阀组模块、传动组件、活塞杆、缸筒和驱动装置;两个缸筒连接于阀组模块两端,活塞杆的两端插入左右两侧缸筒的内孔中,活塞杆与缸筒之间密封且滑动连接,活塞杆与缸筒之间形成驱动腔;驱动装置通过控制进入两个驱动腔内油液的流量和方向来驱动活塞杆沿着缸筒轴线方向直线运动;传动组件包括转轴和摇杆,转轴转动连接于阀组模块,活塞杆移动驱动转轴转动,转轴连接有连接臂,摇杆一端转动连接于连接臂,阀组模块固定连接于主支柱,摇杆端部连接于旋转套筒。通过传动组件将活塞杆直线运动转化为旋转运动,节省安装空间;驱动控制器与执行机构一体化设计,装置结构更加紧凑,重量更轻。
