Abstract
The invention relates to a steel pressure-bearing disc assembly for a brake device and belongs to the technical field of aviation machines. The deformation of a pressure-bearing disc under high pressure can be reduced. In the prior art, due to the fact that a brake shell and a steel pressure-bearing disc assembly are connected through high-strength bolts, the steel pressure-bearing disc assembly is deformed after bearing axial force in the braking process, and the high-strength bolts for connecting the brake shell 3 with the steel pressure-bearing disc assembly are broken frequently. By the adoption of the steel pressure-bearing disc assembly for the brake device, rigidity is reduced when connecting strength is guaranteed through a transition structure, the stressed portion of the steel pressure-bearing disc is transferred to the force-bearing end, force transmitted to the connecting end from the force-bearing end is reduced, and the service life of the high-strength bolts and the brake device is effectively guaranteed.
Description
Technical field
The present invention relates to a kind of braking device steel bearing disc assembly, belong to aviation machine technical field, the bearing disc deformation under high pressure can be reduced.
Background technique
As shown in Figure 1-2, aircraft brake wheel is generally made up of wheel assemblies and braking device.Braking device is made up of assemblies such as cylinder seat assembly, brake disc assembly 1 and brake shell 3; Brake disc assembly 1 generally has compression plate, Moving plate, quiet dish, bearing disc and steel bearing disc assembly 2 to form.When after aircraft landing, brake system obtains delivery pressure signal by aircraft brake instruction sensor (pedal).The delivery pressure being converted into brake system is input in cylinder seat assembly by this pressure signal, and cylinder seat promotes the piston assembly motion be arranged on wherein and produces piston thrust; The thrust of piston is applied on steel bearing disc assembly, and the surface friction drag distance that aircraft then produces on brake disc by the axial force acting on brake disc is braked.Aircraft to be obtained kinetic energy and converts heat energy to brake disc temperature is raised producing surface friction drag by brake disc in the process of braking aircraft, and general steel bearing disc assembly and brake shell need to bear the high temperature up to 600 DEG C to 1200 DEG C.
In aircraft landing mission, because brake system has anti-slip function, will constantly to pressurize, pressure release at least 20 times.Therefore, in the whole lifetime that main wheel uses, steel bearing disc needs to work about 100000 times under the high temperature condition of 600 DEG C to 1200 DEG C and under the effect of the end thrust of 72600N.
In Fig. 1, steel bearing disc is a kind of monolithic construction, is fixed on brake disc by the projection of end, and during owing to installing brake disc in outfield, first must pull down braking device and remove cylinder seat assembly, line maintainability is poor.In Fig. 2, steel bearing disc is one piece of circular plate, be connected on brake shell and brake disc by high-strength bolt, because brake shell 3 and steel bearing disc assembly 2 are connected by high-strength bolt 3, to deform after in brake process, steel bearing disc assembly 2 bears axial force, according to the braking device Experience for Repairing of multiple model, find to connect brake shell 3 situation that occur rupture frequent with the high-strength bolt 3 of steel bearing disc assembly 2.In addition, in use often there is the fracture of steel seal ring, scratch the situation of wheel assemblies in aircraft brake wheel.
Summary of the invention
Often occur rupturing and seal ring processed ruptures, scratches the situation of wheel assemblies for solving the high-strength bolt connecting brake shell and steel bearing disc.The present invention proposes a kind of braking device steel bearing disc assembly.
Braking device steel bearing disc assembly of the present invention, comprises pressure-bearing cup, rivet and steel bearing disc, and the base plane of wherein said pressure-bearing cup is directly fitted in the end face of brake disc assembly, and the top of pressure-bearing cup is sphere; Described steel bearing disc is dish-like, in butterfly underpart and upper end portion, there is loop configuration, and in the outside of upper end portion loop configuration, there is axial annular projection, described underpart loop configuration is fixedly mounted on the end of brake shell by high-strength bolt, described upper end portion loop configuration is connected with pressure-bearing cup by rivet; The height D of described axial annular projection and the ratio of section thickness C are greater than 2, and the section thickness B of described dish-like main body is less than or equal to 0.5 with the ratio of the section thickness C of the section thickness A of underpart loop configuration, upper end portion loop configuration.
The section thickness A of described underpart loop configuration: the section thickness B of dish-like main body: the section thickness C of upper end portion loop configuration is 2:1:2.
Be prefabricated with taper chamfering at the endoporus of described steel bearing disc, carry out installation during for being installed to braking device and guide.
The connecting end larger compared to thickness and load end, the changeover portion thickness through design only has above-mentioned half.This transition structure reduces rigidity while ensure that linking intensity, the force part of steel bearing disc is made to move to load end, reduce the power that load end transmits to connecting end, make the in use suffered pulling force of high-strength bolt reduce 1/3, effectively ensure that the working life of high-strength bolt and braking device.
Pressure-bearing cup one end that the present invention uses is plane, one end is sphere.Planar ends and the bearing disc in braking device are that face contacts, and sphere end and steel bearing disc are point, linear contact lay, compensate due to after steel bearing disc stress deformation by the structure of plano-spherical, and pressure-bearing cup rotates with bearing disc end face, is separated with bearing disc local deformation.Make pressure-bearing cup carry out face with bearing disc all the time by spheric structure to contact, improve all even conformity that steel bearing disc riveted joint pressure-bearing cup portion position is stressed.
