The invention relates to a landing gear with a load cell (10). The landing gear comprises an outer tube (20), an inner tube (30) movably mounted in the outer tube, and a transmission assembly (40) comprising at least one main shaft (42) driven by a gear (41). A spindle (42) is fed through a spindle opening (24) in a spindle bearing plate (21) which is in contact with the outer tube (20) and on which a spindle nut (31) fastened to the inner tube (30) is held. The invention solves the problem by providing a landing gear that allows quantitative and reproducible measurements of forces transmitted from the landing gear to the ground. The problem is solved in that the load cell (10) is mounted on a bearing part (15, 21) which is arranged in the force flow between the main shaft (42) and the outer tube (20).
本发明涉及具有测力元件(10)的起落架。起落架包括外管(20)、内管(30)和传动组件(40),内管可移动地安装在外管中,传动组件包括由齿轮(41)驱动的至少一个主轴(42)。主轴(42)进给穿过主轴轴承板(21)中的主轴开口(24),主轴轴承板与外管(20)接触,且紧固到内管(30)的主轴螺母(31)被保持在主轴上。本发明通过提供起落架来解决问题,起落架允许对从起落架传递到地面的力的定量且可再现测量。问题解决在于测力元件(10)安装在支承部件(15、21)上,支承部件设置在主轴(42)和外管(20)之间的力流中。
