Abstract
The utility model relates to a kind of automobile brake discs, it include: work department, disk-like structure in a ring, the two sides of work department are the working face being in contact with friction block, the air duct of multiple connection work department outer edges and inward flange is formed between two working faces, and each air duct is twist distributed along the circumferential direction of work department；Mounting portion is connected on a wherein working face for work department, for brake disc to be connect with wheel hub.Multiple air ducts being twist distributed are arranged in the utility model on the disc brake rotor, and relative to the brake disc in existing radiation air duct, the brake disc drafting efficiency of this structure type is obviously improved, and brake disc temperature is effectively reduced；Meanwhile with it is existing by way of increasing brake disc quality compared with, and smaller thickness can be used, reduces total quality, for realizing that vehicle loss of weight has very big facilitation, be conducive to automotive light weight technology development, therefore practicability with higher and promotional value.
Description
Technical field
The utility model relates to a kind of auto parts and components more particularly to a kind of automobile brake discs.
Background technique
In current automotive industry, most basic component part of the brake as braking system, function is to subtract automobile
Speed remain stationary state.And during car deceleration, since long-time is braked, it is easy to cause brake disc temperature excessively high,
The problem of braking ability heat fading.
There are two types of existing solutions to the problems described above: one is by way of increasing brake disc Quality advance thermal capacity
It reduces brake disc temperature rise, but effect is less desirable, and is unfavorable for automotive light weight technology development；Another kind is to set on the disc brake rotor
The air duct in radiation distribution is set, but its structure is unfavorable for the flowing of air, brake disc radiating efficiency is lower.
Utility model content
In view of the above problems, the object of the present invention is to provide one kind from heavy and light and breezy automobile brake disc.
A kind of automobile brake disc, comprising: work department, disk-like structure, the two sides of the work department are and friction in a ring
The working face that block is in contact is formed with the wind of multiple connection the work department outer edges and inward flange between two working faces
Road, and each air duct is twist distributed along the circumferential direction of the work department；Mounting portion is connected to wherein the one of the work department
On working face, for brake disc to be connect with wheel hub.
The automobile brake disc, it is preferred that the air duct ecto-entad is tapered.
The automobile brake disc, it is preferred that the mounting portion is cylindrical in shape, and open end is connected in the work department,
Closed end forms mounting surface, offers multiple brake disc fixation holes on the mounting surface.
The automobile brake disc, it is preferred that the quantity in the air duct is at least 36.
The automobile brake disc, it is preferred that the quantity of the brake disc fixation hole is at least four.
Because the utility model adopts the above technical scheme, it has the following advantages: the utility model is set on the disc brake rotor
Multiple air ducts being twist distributed are set, relative to the brake disc in existing radiation air duct, the brake disc of this structure type is divulged information
Efficiency is obviously improved, and brake disc temperature is effectively reduced；Meanwhile with it is existing by way of increasing brake disc quality compared with, and can
Using smaller thickness, total quality is reduced, for realizing that vehicle loss of weight has very big facilitation, is conducive to automotive light weight technology
Development, therefore practicability with higher and promotional value.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the front view of the utility model；
Fig. 3 is the side view of the utility model；
Fig. 4 is the cross-sectional view of the utility model.
Specific embodiment
The preferred embodiment of the utility model is described in detail below with reference to attached drawing, to be clearer to understand this reality
With novel objects, features and advantages.It should be understood that embodiment shown in the drawings is not the limit to the scope of the utility model
System, and simply to illustrate that the connotation of technical solutions of the utility model.
As shown in fig. 1 to fig. 4, automobile brake disc provided in this embodiment includes: work department 1, in a ring disk-like structure, work
The two sides for making portion 1 are the working face being in contact with friction block, are formed with outside multiple connection work departments between two working faces
The air duct 3 of edge and inward flange, and each air duct 3 is twist distributed along the circumferential direction of work department 1；Mounting portion 2 is connected to work department 1
A wherein working face on, for brake disc to be connect with wheel hub.
Automobile brake disc provided in this embodiment is in moderating process, the work face contact of friction block and 1 two sides of work department,
Brake force is generated by friction, the heat a part for the generation that rubs is absorbed by friction block, and another part is braked disk absorption, braking
When disk is rotated with wheel, air enters air duct 3 from 1 outer edge of work department, can efficiently take away brake disc heat by cross-ventilation,
Reduce rapidly brake disc temperature.
In the above-described embodiments, it is preferred that 3 ecto-entad of air duct is tapered, can reduce air in this way and enters air duct 3
Resistance, divulge information more smooth, while making air in 3 exit high speed ejection of air duct, quickly take away brake disc heat to form convection current
Amount.
In the above-described embodiments, it is preferred that mounting portion 2 is cylindrical in shape, and open end is connected in work department 1, closed end shape
At mounting surface, multiple brake disc fixation holes 4 are offered on the mounting surface, to be connected by boss bolt with wheel hub.
In the above-described embodiments, it is preferred that the quantity in air duct 3 is at least 36, and quantity is corresponding with temperature drop demand.
In the above-described embodiments, it is preferred that the quantity of brake disc fixation hole 4 is at least four, quantity and vehicle gross mass
It is corresponding.
The various embodiments described above are merely to illustrate the utility model, wherein the structure of each component, connection type and manufacture craft
Etc. may be changed, all equivalents and improvement carried out on the basis of technical solutions of the utility model,
It should not exclude except the protection scope of the utility model.
