Abstract
The invention relates to a novel brake disc which comprises a disc body and an axle hole formed in the centre of the disc body. The disc body is evenly provided with heat dissipation through holes. The heat dissipation through holes are cone-frustum-shaped holes and are perpendicular to the disc body. The heat dissipation through holes are arranged in the disc body in a forward and reverse alternate mode. Since the disc body is evenly provided with the heat dissipation through holes, the surface area of the outer surface of the disc body of the brake disc is multiplied, and the heat dissipation performance of the brake disc is also multiplied; moreover, since the heat dissipation through holes are the cone-frustum-shaped holes, in the rotating process of the brake disc, air forms differential pressure and rotational flow in the cone-frustum-shaped holes according to the principle of the aerodynamics, the heat dissipation effect of the surfaces of the cone-frustum-shaped holes is improved, the service life of the brake disc is prolonged, and the braking safety performance of a car is improved; since the cone holes with big diameters and small diameters are arranged in the disc body alternately, heat dissipation of the surfaces of the two sides of the brake disc is uniform, and local heat accumulation will not happen.
Description
Technical field
The present invention relates to a kind of automobile braking device, particularly a kind of new brake dish.
Background technique
Automobile brake disc is the critical component of automobile brake, concerns the driving safety of automobile, and the heat dispersion of brake disc affects the working life of brake disc and the safety coefficient of traveling; Current brake disc is when long skidding, and heating is comparatively severe, and brake disc can produce local deformation, and the working life of brake disc reduces, and the brake safe performance of automobile declines.
Summary of the invention
The invention provides a kind of new brake dish, comparatively severe to solve the heating of above-mentioned brake disc, brake disc can produce local deformation, and the working life of brake disc reduces, the technical problem of the brake safe performance decline of automobile.
In order to solve the problems of the technologies described above, the invention provides a kind of new brake dish, comprise the axis hole be provided with in the middle of disk body and disk body, described disk body is evenly provided with thermal vias, described thermal vias is taper type hole, described thermal vias perpendicular to described disk body, and is just put, be invertedly arranged alternately with each other on described disk body.
The invention has the beneficial effects as follows: due to disk body being evenly provided with thermal vias, the surface area of such brake disc circle body outer surface will be multiplied, and its heat dispersion also can significantly improve; Further, thermal vias is frustum hole, when brake disc when rotated, due to aerodynamic principle, air forms pressure reduction and eddy flow in frustum hole, accelerates the radiating effect of frustum hole surface, thus improves the working life of brake disc and the brake safe performance of automobile; Because the large path of taper hole is arranged alternately with each other on disk body, the heat radiation of brake disc both side surface is very even, can not produce the situation that amount of localized heat is assembled.
Further, described disk body is provided with through hole diametrically, described through hole and described frustum hole mutually through.
Adopt the beneficial effect of above-mentioned further scheme to be: disk body is provided with through hole diametrically, is convenient to the diffusion of disk body internal heat, meanwhile, through hole and frustum hole mutually through, increase the radiating efficiency of disk body entirety.
Further, described through hole and described disk body are formed radially angle.
Adopt the beneficial effect of above-mentioned further scheme to be: through hole and disk body are formed radially angle, when brake disc rotates, have lasting, a large amount of air by through hole, the radiating efficiency of brake disc reaches best.
Further, the material of described brake disk body is carbon fiber reinforced carbon matrix composite material.
Adopt the beneficial effect of above-mentioned further scheme to be: carbon fiber reinforced carbon matrix composite material has the advantages such as density is low, thermal capacitance is large, specific strength is high, good thermal stability, the overall weight of brake disc reduces.
Further, the material of described brake disk body is carbon/silicon carbide ceramic matrix composite.
The beneficial effect of above-mentioned further scheme is adopted to be: silicon ceramic matric composite has higher creep strength and toughness, high heat-conducting property and lower linear expansion coeffcient, and not by the impact of the environment such as sleet, materials chemistry stability and good stability of the dimension; The features such as brake disc long service life, braking quality are excellent.
Accompanying drawing explanation
Fig. 1 is the structural representation of new brake dish of the present invention,
Fig. 2 is A-A direction sectional view in new brake dish Fig. 1 of the present invention.
In accompanying drawing, the list of parts representated by each label is as follows:
1, disk body, 2, frustum hole, 3, through hole, 4, axis hole
Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
The structural representation of new brake dish of the present invention, see Fig. 1, comprises disk body 1, is provided with axis hole 4 in the middle of disk body 1, disk body 1 is evenly provided with the frustum hole 2 of heat radiation, and frustum hole 2 is perpendicular to disk body 1, and taper hole 2 is just put, be invertedly arranged alternately with each other on disk body 1; Disk body 1 is provided with through hole 3 diametrically, and through hole 3 is mutually through with frustum hole 2; Through hole 3 and disk body 2 are formed radially angle; The material of brake disk body is carbon fiber reinforced carbon matrix composite material.
Due to disk body being evenly provided with thermal vias, the surface area of such brake disc circle body outer surface will be multiplied, and its heat dispersion also can significantly improve; Further, thermal vias is frustum hole, when brake disc when rotated, due to aerodynamic principle, air forms pressure reduction and eddy flow in frustum hole, accelerates the radiating effect of frustum hole surface, thus improves the working life of brake disc and the brake safe performance of automobile; Brake disc has good thermal stability, and the overall weight of brake disc reduces.
Disk body is provided with through hole diametrically, is convenient to the diffusion of disk body internal heat, meanwhile, through hole and frustum hole mutually through, increase the radiating efficiency of disk body entirety; When brake disc rotates, have lasting, a large amount of air by through hole, the radiating efficiency of brake disc reaches best.
Be described in detail new brake dish of the present invention above, apply specific case herein and set forth principle of the present invention and mode of execution, the explanation of above embodiment just understands core concept of the present invention for helping; Meanwhile, for one of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
