The invention discloses a passive frame positioner of a frame type undercarriage and an oil filling method, the passive frame positioner of the frame type undercarriage comprises a piston rod, a floating piston is installed in an inner cavity of the piston rod, the floating piston divides the inner cavity of the piston rod into a cavity A and a cavity B1, and the cavity B1 is communicated with the cavity A and the cavity B1. A damping piece is installed at the end of the other end of the piston rod, the other end of the piston rod is plugged in an inner cavity of a plunger, the inner wall of the piston rod is matched with the outer wall of the plunger, a limiting piece is fixedly installed at the end, located on the outer side of the piston rod, of the plunger, and the plunger and the piston rod are integrally installed in an inner cavity of an outer cylinder. One end of the piston rod extends out of the outer cylinder, and an end cover is fixed to the other end of the outer cylinder in a sealed mode. The two-way damping device is simple in structure, few in parts and good in damping effect, and frame positioning and sliding oscillation two-way damping of the frame type undercarriage can be achieved.

    本发明公开了一种车架式起落架无源式车架定位器及充油方法,一种车架式起落架无源式车架定位器,包括活塞杆,所述活塞杆内腔中安装有浮动活塞,所述浮动活塞将所述活塞杆的内腔分为A腔和B1腔,所述活塞杆另一端的端部安装有阻尼件,所述活塞杆另一端塞于柱塞内腔中,所述活塞杆的内壁与所述柱塞的外壁配合,所述柱塞位于所述活塞杆外侧的端部固定安装有限位件,所述柱塞和所述活塞杆整体装于外筒内腔中,所述活塞杆的一端伸出所述外筒,所述外筒的另一端密封固定有端盖。本发明结构简单,零件少,减震阻尼效果好,可以实现车架式起落架的车架定位和滑跑振荡双向阻尼。
