Embodiment Construction

[0014] Referring to the accompanying drawings, usually the microswitch 1 of the aircraft landing gear is fixed on the anti-twist arm link 2 of the landing gear, and in addition, the support arm 3 corresponding to the switch contact lever 8 of the microswitch is provided on the landing gear pillar. , the length of the switch contact rod 9 at the front end of the micro switch is adjustable. The aircraft obtains the state signal of the main landing gear through the contact or disconnection relationship between the switch contact lever 8 of the micro switch and the support arm 3 . In aircraft production, the installation requirements of the micro switch 1 not only require to ensure that when the landing gear strut is stretched, the micro switch can continue to be pressed into a certain distance after the micro switch is turned on, but also require to ensure that the landing gear strut is compressed to a certain compression amount.

[0015] The present application provides a micro-...

Abstract

The invention relates to a method and a device for adjusting an inching switch of an aircraft landing gear, a body of the device is a box-shaped cavity, a movable stop block is embedded in the box-shaped cavity, a pressing screw rod is arranged on the box-shaped cavity, the front end of the pressing screw rod is connected with the movable stop block, and the pressing screw rod is rotated to drive the movable stop block to move left and right in the box-shaped cavity. The movable stop block is driven by the pressing screw rod, so that the distance between the movable stop block and the inching switch body simulates the distance between the inching switch body and the support arm in a complete extension state and a contraction state of the aircraft landing gear, and then the length of a contact rod of the inching switch is adjusted.

Description

technical field [0001] The invention relates to the field of aircraft design and manufacture, in particular to an adjustment method and an adjustment device for an aircraft landing gear micro switch, which are used for installation and adjustment of the main landing gear micro switch of an aircraft and simulation verification of the landing gear under retractable state. The reliability of the micro switch ensures that the anti-skid braking system, the air-to-ground signal system and the anti-mistake system provide accurate status signals of the main landing gear. Background technique [0002] The switch used in the landing gear indicating system of a certain type of civil aircraft is a contact push micro switch. The system provides status signals of the main landing gear. The design requires the adjustment of the micro switch. It is required to ensure that when the landing gear strut is extended, the switch can continue to be pressed for a certain distance after it is turne...
