Description of the drawings
Fig. 1 is the sectional structure chart of the present invention;
In figure:1, linear displacement transducer, 2, cylinder block, 3, indicating arm, 4, brake disc component.
Fig. 2 is indicating arm sectional structure chart of the present invention;
In figure:31, pull rod, 32, iron core, 33, adjusting washer.
Specific implementation mode
The following further describes the specific embodiments of the present invention with reference to the drawings.
Referring to Fig.1, Fig. 2, a kind of airplane wheel disk type brake wear indicating device is by linear displacement transducer 1, cylinder block
2, indicating arm 3, brake disc component 4 form.
Whole linear displacement transducer 1 is in hollow cylindrical, and there are screw threads for outer surface, and pass through screw thread and cylinder block 2
On sensor mounting hole be fastenedly connected.The outer end face of linear displacement transducer 1 is limited step, realizes linear displacement transducer
1 with cylinder block 2 install when limit function.
Further, there are fuse holes on the limited step of linear displacement transducer 1 and cylinder block 2, pass through fuse
Ensure that loose phenomenon will not occur after linear displacement transducer 1 is installed.
Indicating arm 3 is hinged with brake disc component 4.Indicating arm 3 runs through 1 central through hole of linear displacement transducer, and stretches out straight
The state of wear of hand inspection brake disc component 4 is convenient in 2 end face of limited step end face and cylinder block of linear movement pick-up 1.
Further, indicating arm is made of pull rod 31, iron core 32, adjusting washer 33.In whole assembly of the invention, pass through
The adjusting washer 33 for increasing different number, different length on pull rod 31, adjusts 32 position of iron core, it is ensured that after whole assembly, iron
32 position of core is in inside 1 central through hole of linear displacement transducer.
In aircraft operational process, due to the use of wheel braking, 4 thickness of brake assemblies is caused to gradually reduce, indicating arm 3
On iron core 32 reduce synchronizing moving to the right with the thickness of brake disc component 4.Ultimately cause the output on linear displacement transducer 1
Corresponding variation occurs for signal.
The operation principle of the present invention is that the linear displacement transducer is installed on the cylinder block, and by fuse into
Row loosens connection, it is ensured that linear displacement transducer will not loosen.The indicating arm is installed on the brake assemblies, when winged
After machine wheel brake is completed, the indicating arm runs through the linear displacement transducer central through hole, and the instruction
The iron core of bar is located in the linear displacement transducer through-hole.After airplane wheel brake mill damage, due to brake disc thickness
Reduce, the indicating arm plunger position changes in the linear displacement transducer through-hole, to make the straight-line displacement
Sensor generates different output signals.Present invention is mainly used for all types of aircrafts using disk type brake wheel to carry out brake disc
Abrasion instruction and analysis.
