Description
Technical field
The invention belongs to aircraft brake field, specifically a kind of steel brake dynamic disk component with steel clamp.
Technical background
Steel brake Moving plate is one of constituent elements of steel brake disc, and it rotates with together with guide rail engagement on wheel hub inner chamber by the keyway on external diameter.When aircraft brake, produce brake torque by the axial brake weight on brake disc, brake torque passes to the guide rail on wheel hub inner chamber by the keyway on Moving plate, finally makes wheel assembly stop operating.
At present, on the steel of most of aircrafts brake Moving plate keyway place all without any protection, therefore larger in aircraft brake moment, while producing high impulsive load, can cause steel brake Moving plate keyway place to occur crackle, affect its working life.
Summary of the invention
In order to improve the intensity at steel brake Moving plate keyway place and the working life of steel brake Moving plate, the present invention proposes a kind of steel brake dynamic disk component that has steel clamp.
The present invention includes the steel clamp of steel brake Moving plate and multiple cuboids.The quantity of described steel clamp is the twice of keyway quantity on Moving plate circumference.There is draw-in groove on a surface at steel clamp length direction, the draw-in groove of described each steel clamp is clamped respectively and is weldingly fixed on two side surfaces in Moving plate keyway, and three internal surfaces of described steel clamp draw-in groove are matched with three outer surfaces of steel brake Moving plate keyway respectively.
The width of described steel clamp is than the large 2～6mm of Moving plate thickness, the low 4～6mm of aspect ratio Moving plate keyway height of steel clamp, and the length of steel clamp is 1/3～2/3 of Moving plate width of keyway.In steel clamp, the degree of depth of draw-in groove is 1.5～3mm.The thickness of steel clamp draw-in groove both sides cell wall is 1～3mm.
In the present invention, steel clamp is to be fixed by welding in steel brake Moving plate keyway place, by the protection of steel clamp, makes steel brake Moving plate keyway place avoid the impact of brake load, intensity and the working life of having improved steel brake disc.
In the time that aircraft normally slides, steel brake Moving plate is along with together High Rotation Speed of wheel hub; When aircraft brake moment, because steel brake Moving plate rotating speed declines rapidly, and in this moment, the speed of wheel hub does not also decline, and therefore, the guide rail on wheel hub has an impulsive load to steel brake Moving plate.In aircraft brake process, due to the sustainable existence of brake weight, at set intervals, the guide rail on wheel hub all has an impulsive load to steel brake Moving plate.In aircraft brake process, due to the buffer function of steel clamp, the impulsive load that acts on steel brake Moving plate keyway place will weaken greatly.Fig. 4 and Fig. 5 are the steel brake Moving plate that is unkitted steel clamp and dress steel clamp intensive analysis result figure while being subject to braking impulsive load; as can be seen from the figure; steel brake Moving plate with steel clamp protection is not than low, more survivable with the suffered stress of the steel brake Moving plate of steel clamp protection.
