Abstract
The utility model relates to a car brake disc with a vent hole, which comprises a brake disk body; the surface of the brake disc body is provided with ribs; the car brake disc is characterized in that the ribs on the surface of the brake disk body are screwed left and right regularly along the circumstance; the surface of the brake disk body is also provided with at least one row of vent holes; and the vent holes are arranged among the ribs which are screwed left and right regularly along the circumstance on the surface of the brake disk body. A plurality of rows of vent holes on the brake surface increase the contact area with the air, has better cooling performance than a common disk; and the cooling ribs are screwed left and right regularly along the circumstance, thereby forcing the air to quickly pass through a heat source with a fan principle and improving the cooling effect of the brake disk.
Description
Technical field
The utility model relates to a kind of parts of automobile, particularly relates to a kind of automobile brake disc with exhaust port, is to the improvement of existing automobile brake disc structure, belongs to Automobile Design and manufacture technology field.
Background technique
At present, the rib of brake disc commonly used is generally the vertical bar shape or the shape that drenches with rain, the sense of rotation that the brake disc of this rib descends heat dissipation direction and automotive wheel in working order at an angle always, influence in time distributing of heat, thereby shorten the working life of brake disc, the smooth no aperture of brake lining also is unfavorable in time removing because of break flour and grit that friction produces simultaneously.
The material of brake disc commonly used is SAE-J431-G3000, is equivalent between China HT200 and the HT250, and material requires to see the following form
| Chemical composition % | C | Si | Mn | P | S |
| Brake disc | 3.20~3.50 | ≤2.30 | 0.60~0.90 | ≤0.15 | ≤ 0.15 |
Brake disc material commonly used does not require adding copper, alloys such as nickel, molybdenum, and graphite length secondary, quantity is less relatively, and not by the alloying element refinement, tensile strength gets final product more than 210MPa the matrix medium pearlite as yet.The hardness height is unfavorable for machining.
Summary of the invention
The purpose of this utility model just is to overcome the prior art above shortcomings, and brake disc can better be dispelled the heat when work, reduces the probability that the brake thermal failure takes place.
The technical solution that the utility model provides is: this automobile brake disc, include the brake disc main body, the surface of brake disc main body is provided with rib, be characterized in that the rib on the described brake disc body surfaces is rule branch left and right sides rotation direction along circumference, also is provided with at least one row's exhaust port on the described brake disc body surfaces.
For following the good the purpose of this utility model of finishing, described exhaust port is arranged on brake disc body surfaces upper edge circumference and is between the rib of rule branch left and right sides rotation direction.
Compared with prior art, the beneficial effects of the utility model are:
1. carbon content height, graphite quantity increases, and has increased thermal conductivity and has improved radiating effect, has also improved the brake disc damping property, reduces brake noise.
2. the many rows exhaust port on the brake lining has increased the area of contact with air, and is better than the thermal diffusivity of common disk.And vent rib is rule branch left and right sides rotation direction along circumference, utilizes the fan principle, forces air to improve the radiating effect of brake disc fast through thermal source.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Specific embodiments
Now, the technical solution of the utility model is described in detail in conjunction with Figure of description and embodiment:
As shown in the figure, the automobile brake disc that the utility model provides, include brake disc main body 1, the surface of brake disc main body 1 is provided with rib 2, rib 2 is rule branch left and right sides rotation direction along the circumference on brake disc main body 1 surface, also be provided with many rows' exhaust port 3 on brake disc main body 1 surface, exhaust port 3 is arranged on brake disc main body 1 surperficial upper edge circumference and is between the rib 2 of rule branch left and right sides rotation direction.
The utility model provides this structural feature of automobile brake disc, determine it after being installed on the automobile, can be consistent with the direction of advance rotation direction of automobile, utilize the fan principle to force air to pass through thermal source fast, the heat energy that helps being produced when automobile brakes in the process of advancing can in time distribute, be the uniform exhaust port of rule and also can make sand grains as being processed with on brake surface, the foreign matters such as break flour that friction is produced easily spill from exhaust port, and the cushioning effect that is produced because of the brake disc fast rotational is got rid of, the assurance brake disc fully contacts with lining, and can absorption portion the friction noise that produced of brake, improve the safety coefficient and the solemn silence of automobile.
In the embodiment who provides, percetage by weight such as following table that automobile brake disc is formed:
Automobile brake disc Chemical composition report (weight %)
This automobile brake disc thermal stress characteristics:
Through machinery system of Taibei university of science and technology with make the test of scientific and technological research institute, they are with the temperature field and add the field of force and do coupling analysis, try to achieve the thermal stress data such as the following table of brake disc:
| Rib shapes | Major principal stress (MPa) | Minimum principal stress (MPa) | Occurrence positions | Rib zone maximum stress (MPa) |
| Existing straight rib | 1010 | -559.22 | The fixed hole edge | 177-200 |
| This automobile brake disc | 1085 | -579.085 | The fixed hole edge | 160-180 |
Above-mentioned test explanation is in polytype rib, and the thermal stress of the rib shape of this automobile brake disc is minimum.This also is one of its characteristic.
Claims (2)
1. automobile brake disc with exhaust port, include the brake disc main body, the surface of brake disc main body is provided with rib, it is characterized in that the rib on the described brake disc body surfaces is rule branch left and right sides rotation direction along circumference, also is provided with at least one row's exhaust port on the described brake disc body surfaces.
2. the automobile brake disc of band exhaust port according to claim 1 is characterized in that described exhaust port is arranged on brake disc body surfaces upper edge circumference and is between the rib of rule branch left and right sides rotation direction.
