Embodiment Construction

[0014] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] refer to figure 1 , figure 2 , an aircraft wheel disc brake wear indicator device is composed of a linear displacement sensor 1, a cylinder seat 2, an indicator rod 3, and a brake disc assembly 4.

[0016] The linear displacement sensor 1 is in the shape of a hollow cylinder as a whole, and there are threads on its outer surface, and is tightly connected with the sensor mounting hole on the cylinder block 2 through the threads. The outer end surface of the linear displacement sensor 1 is a limit step, which realizes the limit function when the linear displacement sensor 1 and the cylinder block 2 are installed.

[0017] Furthermore, there is a fuse hole on the limit step of the linear displacement sensor 1 and the cylinder block 2, and the fuse ensures that the linear displacement sensor 1 will not become loose after installation. ...

Abstract

The invention belongs to the control technology of aircraft wheel brakes, and relates to an aircraft wheel disk type brake wear indicator device. The indicator device comprises a rectilinear displacement sensor, a cylinder block, an indication rod and a brake disc component; the rectilinear displacement sensor is an iron core movable transformer, and is hollow cylindrical overall, and the center of the rectilinear displacement sensor is provided with a through hole; the outside surface of the rectilinear displacement sensor is provided with threads; the cylinder block is a part of an aircraftwheel brake device, and provided with a mounting hole which is internally provided with internal threads matched with the rectilinear displacement sensor; the rectilinear displacement sensor is installed in the mounting hole of the cylinder block; and the brake disc component is fixedly connected to the indication rod.

Description

technical field [0001] The invention belongs to aircraft wheel brake control technology, and relates to an aircraft wheel disc brake wear indicator device. Background technique [0002] In the aircraft wheel brake control system, the brake disc is a key component that affects the landing safety of the aircraft. The performance and wear state of the brake disc will directly affect whether the aircraft can land normally and ensure the safety of personnel and aircraft. When the brake disc is worn to a certain thickness , the brake disc must be replaced. Therefore, the wear status of the brake disc is an inspection item that the ground crew must carry out after each landing of the aircraft. [0003] However, at present, the vast majority of aircraft wheel disc brake wear indicator devices are in the form of mechanical indicators, and the wear status of the brake discs needs to be checked manually. This manual inspection increases the workload of the ground crew, and it is not e...
