装配有摆振衰减器装置的飞行器起落架
摘要：
一种飞行器起落架，该飞行器起落架具有滑动杆和剪式连接件(4)，该滑动杆可滑动地安装在支撑腿部中，而该剪式连接件具有铰接于支撑腿部或者铰接于控制件的转动构件的一个分支(4a)以及铰接于滑动杆的一个分支(4b)，该转动构件用于使得滑动杆转向且安装成在支撑腿部中转动，且这些分支由枢转销(12)铰接于彼此，该起落架装配有摆振衰减器装置(10a、10b)，该摆振衰减器装置放置在摆振衰减器的枢转销上，该衰减器装置包括阈值弹性回复装置和至少一个阻尼装置，该阈值弹性回复装置产生使得分支朝向休止位置回复的力，而该至少一个阻尼装置在分支沿着枢转销轴向地运动时产生阻尼力。该衰减器装置包括两个模块(10a、10b)，这两个模块放置在剪式连接件的任一侧上以与枢转销协配，且每个模块均执行阻尼功能和阈值弹性回复功能中的至少一个。
摘要（英）：

An aircraft undercarriage having a sliding rod slidably mounted in a strut-leg, and a scissors linkage (4) having one branch (4a) hinged to the strut-leg or to a turning element of a control for steering the sliding rod mounted to turn in the strut-leg, and one branch (4b) hinged to the sliding rod, the branches being hinged to each other by a pivot pin (12), the undercarriage being fitted with ashimmy-attenuator device (10a, 10b) placed on the pivot pin of the shimmy-attenuator, the attenuator device including threshold resilient return means generating a force returning the branches towardsa rest position, and at least damping means generating a damping force when the branches move axially along the pivot pin. The attenuator device comprises two modules (10a, 10b) placed on either sideof the scissors linkage in order to co-operate with the pivot pin, each of the modules performing at least one of the damping function and the threshold resilient return function.
