High temperature resistant, second is carbon fiber ceramic composite material, and carbon fiber ceramic composite hardness is high, wear-resisting, high temperature resistant, but carbon
Fibrous ceramic composite price is very expensive, and carbon carbon composite hardness is high, wear-resisting, high temperature resistant, carbon carbon composite brake
Though disk performance is high, expensive, cost performance is not high, and apparent consumption is extremely low.It would therefore be highly desirable to propose that one kind both can guarantee brake
Disk performance and used life can reduce the brake disc of cost simultaneously.
Utility model content
For the disadvantages described above of the prior art, the utility model provides a kind of brake disc, it is intended to solve existing brake disc
The technical issues of cannot be considered in terms of brake disc performance and cost.
To achieve the above object, the utility model provides a kind of automobile brake disc, comprising: a brake disk body and two rub
Pad, brake two end faces of disk body are in dentation, and one end face of friction plate is in dentation, another end face of friction plate is smooth surface, are stopped
Friction plate insertion brake disk body is realized in the dentation end face cooperation of one same friction plate in dentation end face of hull body, wherein is stopped
The material of hull body is cast iron, and the material of friction plate is composite material.
Preferably, friction plate material is carbon fiber ceramic composite material or carbon-carbon composite.
Preferably, brake disc body end face is serrated, and one end face of friction plate is serrated.
Preferably, brake disk body and friction plate are annular in shape.
Preferably, friction plate includes multiple fan-shaped sub- friction plates, and one end face of sub- friction plate is in dentation, sub- friction plate
Another end face is smooth surface.
In general, it can obtain down the above technical solutions conceived by the present invention are compared with the prior art,
Column the utility model has the advantages that
Brake disc provided by the utility model, using brake disk body and friction plate structure, by friction plate be selected as hardness it is high,
Wear-resisting and high-temperature resistant composite material, brake disk body, which is selected as, fabricates cheap cast iron materials, can guarantee to meet vapour
Vehicle brakes under the premise of mechanics and mechanical property requirements, while realizing more than the higher service life of general cast iron brake disc and brake
Vehicle performance, and more than the carbon fiber ceramic composite material or the lower cost of carbon-carbon composite brake disc integrally suppressed.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of automobile brake disc provided by the embodiment of the utility model；
Fig. 2 is an end view of automobile brake disc friction plate provided by the embodiment of the utility model；
Fig. 3 is another end view of automobile brake disc friction plate provided by the embodiment of the utility model；
Fig. 4 is the structural schematic diagram for the automobile brake disc that another embodiment of the utility model provides.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.In addition, institute in the various embodiments of the present invention described below
The technical characteristic being related to can be combined with each other as long as they do not conflict with each other.
As shown in Figure 1, brake disc provided by the utility model, including two friction plates 1 and a brake disk body 2, wherein
The disk body 2 that brakes is in disk form, and brake 2 both sides of the face of disk body are circumferentially serrated, and friction plate 1 is also in disk form, such as Fig. 2 and 3
Shown, 1 one end faces of friction plate are shiny surface, and another side is also circumferentially to be serrated.Friction plate 1 is pre- inserts, is put in advance
Enter in brake disc casting mold, the fusion of friction plate 1 is on the rubbing surface of brake disk body 2 after casting of molten metal, so that friction plate 1 is logical
The toothed surfaces that toothed surfaces are crossed with brake disc 2 cooperate.Wherein, 1 material of friction plate is carbon fiber ceramic composite material or carbon-
Carbon composite, brake disk body 2 are cast iron materials.The main structure brake disk body 2 of brake disc is cast iron materials, can reduce brake
The cost of hull, brake block and Stopper contact, brake pad material are that composite material combines, composite material combination high temperature resistant and resistance to
Mill.Therefore, brake disc provided by the utility model, allows cast iron brake disc in conjunction with composite material, has both protected brake disc hardness height, resistance to
High temperature, it is wear-resisting, brake disc price can also be allowed to substantially reduce, high-performance composite materials brake disc is allowed to popularize market.
In order to prepare above-mentioned brake disc, prepared using following steps:
Step 1: carbon fiber ceramic composite material or carbon-carbon composite are pressed in advance in mold and are fired molding；
Step 2: the inserts deburring that will be formed by a firing is put into brake disc casting die, starts casting gold after positioning
Belong to liquid cast molding.
When composite material is carbon fiber ceramic, carbon fiber ceramic hardness is high, and many fine cracks can be generated after sintering, by
There is carbon fiber connection that can't be broken in inside, these crackles can be complementary ceramic different caused with the coefficient of expansion of cast iron
Size deformation.Carbon fiber ceramic composite material heatproof is higher than gray cast iron fusing point, does the pre- inserts of cast iron brake disc and the heat in later period
Treatment process will not have an impact carbon fiber ceramic material capability, the production of the utility model production process and cast iron brake disc
It is almost the same.
Since there are multiple grooves at 1 back side of friction plate, molten metal casting flow into groove and carbon fiber ceramic composite material or
Carbon-carbon composite is combined closely, it is ensured that product size stability when braking.Groove increases connecing for two kinds of materials
Contacting surface product, can allow heat release hole among the heat transfer of carbon fiber ceramic to cast iron brake disc.
Automobile brake disc provided by the utility model comprising the cast iron brake disc disk body of installation frame as a whole, with
And the friction plate inlayed along disk body circumference.The automobile brake disc can guarantee that meeting braking automobile mechanics and mechanical performance wants
Under the premise of asking, while realizing more than the higher service life of general cast iron brake disc and braking quality, and more than whole compacting
Carbon fiber ceramic composite material or the lower cost of carbon-carbon composite brake disc.
As shown in figure 3, friction plate is made of multiple sub- friction plates 11, every sub- friction plate 11 is fan-shaped, multiple sub- frictions
Piece is combined into circular ring shape, using the structure of sub- friction plate, can reduce the processing cost of friction plate.
As it will be easily appreciated by one skilled in the art that the above is only the preferred embodiment of the utility model only, not
To limit the utility model, any modification made within the spirit and principle of the present invention, equivalent replacement and change
Into etc., it should be included within the scope of protection of this utility model.
