Description
Technical field
The present invention relates to a kind of brake disc of high-speed train, and in particular to a kind of high-speed train braking system with light weight
Change, the composite brake disk of high-effect feature.
Background technology
Brakes is bullet train safety guarantee and emergent critical system.High-speed train braking system is by damper brake
Piece, brake disc, brake clamp, checking cylinder and control system etc. are constituted.Checking cylinder makes brake lining clamp brake disc by brake clamp,
By the friction between brake lining and brake disc, the kinetic energy of bullet train is changed into heat energy, heat energy by brake disc and brake lining dissipate in
Air, so as to reach braking purpose.Traditional brake disc is mostly that, using the metal brake disk of single material, weight is larger, and
And inevitably exist due to reasons such as manufacturing process, inside metal brake disk be mingled with, the defect such as segregation and hole；Together
When, in braking procedure, huge braking thermic load makes brake disc produce very big thermograde, and thus produces thermal stress.
The ringing of the presence of defect and uneven temperature and stress field easily makes brake disc produce micro-crack, when micro-crack expands
Open up when to a certain extent, brake disc will occur fatigue fracture.From the point of view of practice situation, brake disc of high-speed train majority is
Changed because of brake disc surface fire check.Therefore, the hot tearing of brake disc be current bullet train safety arrestment chief threat it
One.
Conventional rails vehicular traffic brake material is difficult to meet the requirement of thermal shock high, high energy load and friction factor high, than
Thermal capacitance is high, density is small, the composite with more efficient energy comes into operation in brake disc in succession.Such as carbon ceramic composite material, i.e.,
Fibre reinforced mends tough carbon-based and silicon carbide-based biradical composite material (C/C-SiC), it has also become the one of brake material of new generation
Individual main direction of studying, has the advantages that high temperature resistant, Gao Biqiang, high abrasion, low-density and full ambient engine are applicable, in aircraft, high speed
The high speed high energy such as train, racing car, port engineering machinery are carried and are with a wide range of applications in brakes, but composite
Brake disc how to realize and wheel combination and improve radiating effect be still a problem urgently to be resolved hurrily.
The content of the invention
Present invention solves the technical problem that being：For the above-mentioned problem that existing composite exists on the disc brake rotor, carry
For a kind of high-speed train braking wheel disc carried with lightweight, high energy with high-effect feature, existing metal brake disk is solved because of heat
Split the installation problem for causing failure and composite brake disk
The present invention adopts the following technical scheme that realization：
Wheel disc is braked in a kind of lightweight of bullet train, including carbon ceramic friction material frictional disk and carbon carbon composite
Skeleton disk；The frictional disk is fixed with skeleton disk and fitted, and is connected with wheel by skeleton disk.
Further, the two sides of the frictional disk is smooth, and annular is uniformly divided centered on the frictional disk center of circle on frictional disk
Some first rivet holes and the 3rd rivet hole are furnished with, the skeleton disk is provided with corresponding second rivet hole and the 4th rivet
Hole, wherein the first rivet hole and the 3rd rivet hole are used to fit frictional disk and skeleton disk by rivet riveting, the second rivet hole
It is used to that circle set will be set after frictional disk and the laminating of skeleton disk with the 4th rivet hole, braked wheel is checked and regulated by body and car by the circle set
Wheel connection.
Further, the inner ring and outer ring of first rivet hole and the second rivet hole respectively close to frictional disk and skeleton disk
It is distributed two groups.
Further, some vent bosses are evenly distributed with the skeleton disk.
Further, the vent bosses are some Y types vent bosses being distributed in a ring centered on the skeleton disk center of circle,
Spaced between the Y types vent bosses is the ventilation slot of 10mm-20mm.
Further, annular is uniformly distributed some cunnings also centered on the skeleton disk center of circle on the vent bosses of the skeleton disk
Block hole, the slider bore is to be fixedly embedded at sliding block borehole jack by rivet in radially arranged mounting hole, the slider bore.
In the present invention, the carbon ceramic friction material of the frictional disk includes following component according to mass percent：20~
28% carbon fiber, 18~32% matrix carbon, 26~45% SiC, 2~6% Si.

35% carbon fiber；65~80% matrix carbon.
Further, the thickness of the skeleton disk is 28mm-40mm, and density is 1.7~1.8g/cm3。
The present invention has the advantages that：
(1) braking wheel disc is made up of the frictional disk of carbon pottery material and the skeleton disk of carbon carbon materials matter, and density is about the 1/ of forged steel
3, the weight loss effect for brakes is obvious.
(2) while possessing more preferable high-temperature behavior and brake efficiency, even if will not also corrode in the oxygen of high concentration, together
When in brake hard ceramic brake wheel disc can consume the energy of nearly 50MJ in theory, and the forged steel disk of better performances also can only
Consumption 20MJ or so.
(3) significant improvement of the carbon pottery frictional disk in terms of braking ability so that the frictional disk that can be made pottery with a carbon replaces two
The service life of individual steel brake disc, is run with a bullet train and calculated over 30 years, and cost accounting shows, using complete
Present invention braking wheel disc, than steel disk brake cost-effective 50%.
In sum, C-base composte material is replaced existing wide variety of steel alloy as the system of bullet train by the present invention
Driving wheel disk material, alleviates train unsprung weight, reduces traction power consume；The hot mechanicalness of braking wheel disc is improve simultaneously
Can, it is possible to reduce the disk number of braking wheel disc；Frictional disk abrasion is in place or after failure, can direct dismounting and change, and skeleton disk can
To utilize always, maintenance cost is reduced.
