An aircraft landing gear assembly (50, 80) includes: a first landing gear element (60) movably coupled relative to a second landing gear element (62) for pivoting about a pivot axis (PA) between a first condition and a second condition; a cam surface (74) defined by the second landing gear element; and a leaf spring having a first end region and a second end region, the first end region of the leaf spring coupled to the first landing gear element for movement therewith, the second end region of the leaf spring comprising a cam follower (72) arranged in moving contact with the cam surface, the first landing gear element is pivotable about the pivot axis such that as the first landing gear element pivots about the pivot axis between a first condition and a second condition, the cam follower moves from a first region (R1) of the cam surface to a third region (R3) of the cam surface via a second region (R2) of the cam surface, the cam surface is shaped such that a distance (RO) between the pivot axis and the cam surface increases between the first region and the second region to define a first gradient, and the distance between the pivot axis and the cam surface varies between the second region and the third region of the cam surface to define a second gradient, the second gradient being gentle than the first gradient.

    一种飞行器起落架组件(50、80),包括:相对于第二起落架元件(62)可移动地联接以绕枢转轴线(PA)在第一状况与第二状况之间枢转的第一起落架元件(60);由第二起落架元件限定的凸轮表面(74);以及具有第一端区域和第二端区域的板簧,板簧的第一端区域联接到第一起落架元件以与第一起落架元件一起运动,板簧的第二端区域包括布置成与凸轮表面运动接触的凸轮从动件(72),使得随着第一起落架元件绕枢转轴线在第一状况与第二状况之间枢转,凸轮从动件经由凸轮表面的第二区域(R2)从凸轮表面的第一区域(R1)运动到凸轮表面的第三区域(R3),其中,凸轮表面定形状成使得枢转轴线与凸轮表面之间的距离(RO)在第一区域与第二区域之间增加以限定第一梯度,并且枢转轴线与凸轮表面之间的距离在凸轮表面的第二区域与第三区域之间变化以限定第二梯度,第二梯度比第一梯度平缓。
