摘要： A semi-levered landing gear for an aircraft comprises a main shock absorber strut (1) with upper and lower telescoping portions, with the upper portion pivotally connectable to the airframe. The landing gear further comprises a bogie beam (4) to extend fore and aft of the airframe with at least one forward axle and one aft axle for respective forward and aft wheels and a main pivot between the forward and aft axle pivotally connected to the lower portion of the main shock absorber strut and an auxiliary actuator mechanism comprising a spring unit (11) pivotally connected at a lower end to an auxiliary pivot on the bogie forward of the main pivot, and at an upper end to an anchor point (112) offset from the pivot connection of the upper portion to the aircraft fuselage so that during stowing both the strut and spring unit pivot together about different pivot points, which causes a relative longitudinal movement between the main pivot and auxiliary pivot that further tilts the bogie beam to a stowing position.

摘要： A semi-levered landing gear for an aircraft comprising:
a main shock absorber strut (1) with upper and lower telescoping portions, with the upper portion connectable to the airframe;
a bogie beam (4) to extend fore and aft of the aircraft fuselage with at least one forward axle and one aft axle for respective forward and aft wheels (7, 7') and a main pivot between the forward and aft axle pivotally connected to the lower portion of the main shock absorber strut;
and an auxiliary actuator mechanism comprising a lever (81) pivotally connected to the upper portion of the main shock absorber strut so as to pivot between a predetermined upper position for take-off, and a lower position, a spring unit (80) pivotally connected at an upper end to the lever and at a lower end to the bogie at an auxiliary pivot forward of the main pivot, and a control linkage (83) connected between the lever and the upper portion of the main shock absorber strut to define said upper predetermined position of the lever, the control linkage being connectable to an anchor point that moves relative to the upper portion of the main shock absorber strut during stowing, whereby the control linkage is operated by initial stowing movement of the stowing mechanism to lower the lever from said upper position to a stowing position.摘要翻译： 一种用于飞机的半摇臂起落架，包括：具有上伸缩部分和下伸缩部分的主减震器支柱（1），其上部可连接到机身; 转向架梁（4），所述转向架梁（4）在所述飞机机身的前后延伸，所述转向架梁具有用于相应的前轮和后轮（7,7'）的至少一个前轴和一个后轴并且所述前轴和后轴之间的主枢轴枢转地连接到 主减震器支柱的下部; 以及辅助致动器机构，该辅助致动器机构包括枢转地连接到主减震器支柱的上部以便在用于起飞的预定上部位置和下部位置之间枢转的杠杆（81），枢转连接的弹簧单元（80） 在杠杆的上端和在主枢轴前方的辅助枢轴处的转向架的下端处，以及连接在杠杆和主减震器支杆的上部之间的控制连杆（83），以限定所述鞋帮 所述控制联动装置可连接至在收起期间相对于所述主减震器支杆的上部移动的锚定点，由此所述控制联动装置通过所述收起机构的初始收起运动来操作以将所述控制杆从 所述上部位置处于收起位置。
