The invention discloses an undercarriage buffer of a modular reverse resistance valve structure. The reverse resistance valve cover, the reverse damping valve core mounting seat and the reverse resistance valve supporting plate are arranged in the compression damping cavity and are positioned at a port, close to the rebound damping cavity, of the compression damping cavity; the reverse resistance valve cover is rigidly connected with the reverse damping valve core mounting seat, and the reverse damping valve core mounting seat is rigidly connected with the reverse resistance valve supporting plate; the throttling valve plate is placed in a valve plate cavity formed between the reverse damping valve cover and the reverse damping valve element mounting seat, and a hole of the throttling valve plate is used for being matched with an oil needle structure; an oil through hole of the reverse resistance valve supporting plate is used for arranging a fixed damping valve element or a reverse damping valve element, and the fixed damping valve element and the reverse damping valve element both face an oil through hole of the reverse resistance valve deck and an oil through hole of the reverse damping valve element installation base. The fixed damping valve element is in transition fit with the reverse resistance valve supporting plate, and the reverse damping valve element is in loose fit with the reverse resistance valve supporting plate so as to move back and forth in the universal hole of the reverse resistance valve supporting plate. Therefore, the damping coefficient of the undercarriage buffer reverse resistance valve can be changed.

    本发明公开了一种模块化反阻阀结构的起落架缓冲器。反阻阀盖、反向阻尼阀芯安装座、反阻阀托板设置于压缩阻尼腔内,且位于压缩阻尼腔的靠近反弹阻尼腔的端口;反阻阀盖和反向阻尼阀芯安装座刚性连接,反向阻尼阀芯安装座和反阻阀托板刚性连接;节流阀片放置于反阻阀盖和反向阻尼阀芯安装座之间构成的阀片腔中,节流阀片的孔用于与油针结构配合;反阻阀托板的通油孔用于设置定阻尼阀芯或反向阻尼阀芯,定阻尼阀芯和反向阻尼阀芯均面向反阻阀盖的通油孔和反向阻尼阀芯安装座的通油孔设置;定阻尼阀芯与反阻阀托板采用过渡配合,反向阻尼阀芯与反阻阀托板采用松配合,以在反阻阀托板的通用孔中前后移动。由此使起落架缓冲器反阻阀阻尼系数可变更。
