Description
Technical field
The invention belongs to the technical fields of motor vehicle braking system.More particularly it relates to a kind of brake disc, in addition,
The invention further relates to the forming technologies of the brake disc.
Background technology
Iron piece is generally in the current brake disc in the prior art, used on automobile, wherein most is cast using ash
Iron, weight are larger.For this purpose, the prior art has developed aluminum Moving plate, but there are no matching in the prior art to rub
Material is wiped, therefore, the technology of aluminum Moving plate can not be promoted the use of in high volume.
The content of the invention
The present invention provides a kind of brake disc, and the purpose is to solve the problems, such as friction material for aluminum brake disc.
To achieve these goals, the technical solution taken of the present invention is：
The brake disc of the present invention, including brake disc body and the drag ring being arranged on brake disc body；The system
Moving plate body uses aluminium, and the drag ring uses cast iron materials.
The drag ring is arranged on two end faces of the brake disc body.
In the drag ring towards on the surface of brake disc body, setting multiple boss or setting multiple pins, stretch
Enter the inside of brake disc body.
The drag ring is arranged on two end faces of the brake disc body；And pass through the boss or pin
Two drag rings at both ends are connected into an entirety.
In the drag ring towards on the surface of brake disc body, equipped with multiple recess, with the brake disc body
The protrusion on surface matches.
In order to realize the goal of the invention identical with above-mentioned technical proposal, the present invention also provides above-described brake discs
Forming technology, technical solution are：
The drag ring is shaped by cast iron, and the ironware of drag ring then is inserted model cavity and is fixed, then is carried out
The aluminium castable of brake disc body, aluminium and the drag ring cast iron materials of brake disc body are firmly combined with, and form whole system
The structure of Moving plate.
The present invention solves the problems, such as friction material, both so that entirely using above-mentioned technical proposal for the brake disc of aluminum
The weight of brake disc mitigates significantly, reduces automobile unsprung mass, and promotion vehicle is handling, reduces oil consumption, reduces noise pollution, system
Moving plate heat-sinking capability is promoted；Meanwhile and brake disc is caused to have good wear-resisting property, the braking effect of brake disc is from shadow
It rings；The body of brake disc and being firmly combined with for drag ring, power transfer unaffected；It is rational in infrastructure, it is simple for process, without adjustment
Friction material formulation in high volume can directly be replaced.
Description of the drawings
It marks and is briefly described as follows in content and figure expressed by attached drawing：
Fig. 1 is the structural profile illustration of the present invention；
Fig. 2 is the drag ring structure diagram of the present invention.
In figure mark for：
1st, brake disc body, 2, drag ring, 3, boss.
Specific embodiment
Below against attached drawing, by the description of the embodiment, making to the specific embodiment of the present invention further details of
Illustrate, those skilled in the art to be helped to have more complete, accurate and deep reason to inventive concept of the invention, technical solution
Solution.
The structure of the expressed present invention as shown in Figure 1, Figure 2 is a kind of brake disc, including
The defects of in order to overcome the prior art, realizes that aluminum brake disc provides the goal of the invention of friction material, and the present invention adopts
The technical solution taken is：
As shown in Figure 1 and Figure 2, brake disc of the invention including brake disc body 1 and is arranged on brake disc body 1
Drag ring 2；The brake disc body 1 uses aluminium, and the drag ring 2 uses cast iron materials.
Two kinds of materials are merged by above-mentioned technical proposal by casting, are firmly combined with, can effectively be reduced existing iron
Moving plate weight；And it because drag ring is cast iron materials, is matched with having friction material in the market, can directly switch use；It can be effective
Brake disc weight is reduced, and adapts to existing friction material.By the rubbing surface of aluminum Moving plate using cast iron materials, can directly match existing
There is friction material system in the market.Its advantage is：1st, automobile unsprung mass is reduced, promotion vehicle is handling, reduces oil
Consumption, reduces noise pollution, and brake disc heat-sinking capability is promoted；2nd, friction material formulation need not be adjusted, in high volume can directly replace makes
With.
The drag ring 2 is arranged on two end faces of the brake disc body 1.
In the drag ring 2 towards on the surface of brake disc body 1, setting multiple boss 3 or set multiple pins
Nail stretches into the inside of brake disc body 1.
The drag ring 2 is arranged on two end faces of the brake disc body 1；And pass through the boss 3 or
Two drag rings 2 at both ends are connected to become an entirety by pin.
Two drag rings 2 at both ends are connected into an entirety, the integral rigidity and intensity of brake disc can be improved, and then
Improve the braking friction properties of brake disc.Therefore, cast iron drag ring 2 model manufacturing and during cast it is necessary to being poured into a mould
For an entirety.At this point, drag ring 2 shown in Fig. 2 should be made to two panels, and boss 3 (be made pin also can) is opposite and connects
2 structure of monoblock type drag ring
In the drag ring 2 towards on the surface of brake disc body 1, equipped with multiple recess, with the brake disc sheet
The protrusion on 1 surface of body matches.
By on irony drag ring 2, producing boss or pit or pin etc. (such as Fig. 2), make aluminum brake disc sheet
Body 1 and irony drag ring 2 merge securely；Braking moment can be effectively transferred simultaneously, ensure that drag ring 2 is not easy with brake disc body 1
Separation.
In order to realize the goal of the invention identical with above-mentioned technical proposal, the present invention also provides above-described brake discs
Forming technology, technical solution are：
The drag ring 2 is shaped by cast iron, and the ironware of drag ring 2 then is inserted model cavity and is fixed, then into
The aluminium castable of row brake disc body 1, aluminium and 2 cast iron materials of drag ring of brake disc body 1 are firmly combined with, and are formed whole
The structure of system Moving plate.
This programme makes drag ring 2 for cast iron materials (such as Fig. 1) on the basis of aluminum Moving plate, the method mainly realized be
In aluminum brake disc body casting process, irony drag ring 2 (such as Fig. 2) is placed in die cavity, cast molding together.Pass through two
Aluminum brake disc body 1 and irony drag ring 2 are merged by secondary casting, can effectively reduce brake disc weight；While and city
Existing friction material matches on field, can in high volume use.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements and from aforesaid way
Limitation, as long as employ the inventive concept and technical scheme of the present invention progress various unsubstantialities improvement or without changing
Other occasions are directly applied to by the design of the present invention and technical solution, within protection scope of the present invention.
