摘要： An auxiliary mechanism includes a lever unit, a spring unit and a positioning unit. One of the units pivotally connects to the upper portion of a main shock absorber strut so as to pivot between a predetermined lower position for take-off and landing and an upper position. Another unit pivotally connects at an upper end to the upper portion of the main shock absorber strut and pivotally connects at a lower end to the first unit. A third unit pivotally connects at a lower end to the bogie beam at an auxiliary pivot and connects at an upper end to the lever. The positioning unit assumes either a contracted state or extended state for taxiing, take-off and landing, and assumes the other state for stowing the landing gear after take-off. The spring unit provides spring resistance to pivotal movements of the bogie beam about the main pivot during taxiing.

摘要： A semi-levered landing gear for an aircraft includes a main shock absorber strut, a bogie beam and an auxiliary actuator mechanism. The bogie beam extends fore and aft of an airframe of the aircraft with forward and aft axles 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. The auxiliary actuator mechanism includes a spring unit 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 offset from the pivot connection of the upper portion to the aircraft fuselage. During stowing the strut and spring unit pivot together about different pivot points, causing a relative longitudinal movement between the main pivot and auxiliary pivot that further tilts the bogie beam to a stowing position.
摘要翻译： 用于飞行器的半起落架起落架包括主减震器支柱，转向架梁和辅助致动器机构。 转向架梁用于相应的前轮和后轮的前轮和后轴的飞机机身的前后延伸，并且前后轴之间的主枢轴枢转地连接到主减震器支柱的下部。 辅助致动器机构包括弹簧单元，该弹簧单元在下端处枢转地连接到主枢轴前方的转向架上的辅助枢轴上，并且在上端处于从上部的枢转连接偏离飞行器机身的锚定点。 在收起期间，支柱和弹簧单元围绕不同的枢转点枢转在一起，导致主枢轴和辅助枢轴之间的相对纵向运动，其进一步将转向架梁倾斜到收起位置。

摘要： An auxiliary actuator mechanism includes a lever, a spring unit and a control linkage. The lever is pivotally connected to the upper portion of a main shock absorber strut, and pivotable between an upper position for take-off, and a lower position. The spring unit is 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. The control linkage is connected between the lever and the upper portion of the main shock absorber strut to define the upper predetermined position of the lever. The control linkage is connectable to an anchor point that moves relative to the upper portion of the main shock absorber strut during stowing, and is operated by initial stowing movement of the stowing mechanism to lower the lever from the upper position to a stowing position.
摘要翻译： 辅助致动器机构包括杆，弹簧单元和控制连杆。 杠杆枢转地连接到主减震器支柱的上部，并且可以在用于起飞的上部位置和下部位置之间枢转。 弹簧单元在上端枢转地连接到杠杆，并且在下端处以主枢轴前方的辅助枢轴枢转地连接到转向架。 控制联动装置连接在杠杆和主减震器支柱的上部之间，以限定杠杆的上部预定位置。 控制联动装置可连接到在收起期间相对于主减震器支柱的上部移动的锚点，并且通过收起机构的初始收起运动来操作以将杠杆从上部位置降低到收起位置。
