The invention relates to the technical field of sensors, and discloses a long-life aircraft brake instruction sensor, which comprises a shell, an ejector rod and a push rod, a front end cover and a rear end cover are respectively arranged at two ends of the shell, a bushing is fixedly mounted on the front end cover, the push rod is in sliding fit with the bushing, the push rod is made of a 9Cr18Mo material, and the ejector rod is made of a stainless steel material. The lining is made of a 1Cr17Ni2 material; the ejector rod is arranged in the push rod and is in sliding fit with the push rod, a first spring is arranged between the ejector rod and the push rod, a coil assembly is arranged in the shell, armatures are slidably connected into axial through holes of the coil assembly respectively, and the ends, extending out of the coil assembly, of the armatures are fixedly connected with the push rod. According to the airplane brake instruction sensor with the long service life, the problem that the service life is short due to clamping stagnation of a movable part and failure of a spring of an existing brake instruction sensor is solved.

    本发明涉及传感器技术领域,公开了一种高寿命的飞机刹车指令传感器,包括壳体、顶杆和推杆,所述壳体的两端分别设有前端盖和后端盖,所述前端盖上固定安装有衬套,所述推杆与衬套滑动配合,所述推杆采用9Cr18Mo材料制成,所述衬套采用1Cr17Ni2材料制成;所述顶杆设置在推杆内且二者之间滑动配合,所述顶杆与推杆之间设有第一弹簧,所述壳体内设有线圈组件,所述线圈组件的轴向通孔内分别滑动连接有衔铁,所述衔铁伸出线圈组件的一端与推杆固定连接;本发明提供的一种高寿命的飞机刹车指令传感器,解决了现有刹车指令传感器的活动部件存在卡滞、弹簧失效进而导致使用寿命不足的问题。
