Abstract
The invention discloses an automobile brake disc, wherein a plurality of arc-transition columnar reinforcing ribs (1) are distributed with interval between and connected to the inner end face of a brake disc body connected with a flange, so as to form mutually communicated ventilation cavities in the disc body. The brake disc to which a plurality of columnar reinforcing rib structures are distributed and connected has the following advantages that: firstly, when the braking of an automobile produces severe alternating load action, cracks caused by stress concentration produced by the disc body are obviously eliminated; and secondly, due to the mutual communication of the ventilation cavities of the disc body and the increase of the number of air inlets and air outlets of the ventilation cavities, according to the principles of air fluid mechanics, the air inlets and the air outlets which are formed through the distribution of the arc-transition columnar reinforcing ribs increase inlet air flow, reduce the air resistance of cooling air circulated in the ventilation cavities, realize that the cooling air produced in different directions because of the changes of automobile speed can smoothly enter the mutually communicated ventilation cavities of the disc body so as to lower the temperature and cool, strengthen ventilation and heat dispersion effects, and effectively increase the life span of the brake disc.
Description
(1) technical field: the present invention relates to the brake system of car parts; Be specifically related to a kind of automobile brake disc.
(2) background technique: the structure of automobile brake disc in the prior art is to be connected on the interior edge face of braking lamellar body with flange at its braking lamellar body, is the radial casting of spacing and is connected with a plurality of vented cavities in a plurality of straight rectangular stiffening ribs formation disk bodies.But each vented cavity has only one into and out of the air port.It exists not enough: the one, and the braking brake disk body meets with stresses and concentrates greatly.When the violent alternate load that the automobile brake brake is produced is done the time spent, at the adjacent straight rectangular stiffening rib adjoining edge place of described disk body vented cavity two, the stress that produces is concentrated very big, cause the disk body working strength obviously to descend, the disk body end capacity check then occurs when serious, reduced the working life of brake disc.The 2nd, result of ventilating heat dissipation is poor.Be connected in the size of brake disc vented cavity air output on the automotive hub, be to change according to automobile driving speed to change its cooling air approach axis and size, because each ventilation inner chamber has only one to advance, exhaust outlet, when extraneous cooling air changes direction of the traffic and size, enter the cooling air of disk body vented cavity, a part enters vented cavity by intake grill and carries out radiating and cooling and discharge from exhaust outlet, another part then enters the not corresponding vented cavity of the flow direction because of wind direction, carried the retaining or the intake grill that backflows out by straight rectangular stiffening rib, reduced the smooth and easy vented cavity that enters of extraneous cooling air flow to the disk body cooling of in time lowering the temperature, when often causing temperature to rise to 500 ℃～600 ℃ high temperature because of disk body cooling cooling is untimely, cause the disk body materials microstructure to change, original pearlite material structure high temperature is degenerated become the ferrite material tissue, cause the disk body working strength to reduce and disk body distortion or crowfoot cracks occur, reduced its working life.
(3) summary of the invention: the deficiency at above-mentioned prior art exists, the object of the present invention is to provide a kind of automobile brake disc, reduce disk body stress when being intended to braking brake and concentrate, the enhancing result of ventilating heat dissipation also improves its working life.
For achieving the above object, the technological scheme of automobile brake disc of the present invention is achieved in that and comprises that mainly the braking lamellar body is connected the braking lamellar body with flange; Be connected on the interior edge face of braking lamellar body with flange at described braking lamellar body, be the spacing distribution and be connected with the vented cavity that is interconnected in several arc transition shape cylindricality stiffening ribs formation disk bodies.
When implementing technique scheme, described several arc transition shape cylindricality stiffening ribs are water droplet shapes; Water droplet shape and diamond; Water droplet shape and equilateral triangle combination; Water droplet shape, rhombus and equilateral triangle combination; Water droplet shape, rhombus and isosceles triangle combination; It is wherein a kind of that water droplet shape, rhombus, isosceles triangle and equilateral triangle make up.
The present invention distributes and to be connected with several cylindricality reinforcing rib structures by adopting the above-mentioned spacing that is, and the one, do the time spent in the violent alternate load that the automobile brake brake is produced, obviously reduced the stress that disk body is produced and concentrated, eliminated the seminess that disk body occurs.The 2nd, increased the vented cavity that is interconnected in the disk body into and out of air port quantity, the air intake flow obviously increases; Having changed different cylindricality stiffening ribs is arc transition shape body, according to the air fluid mechanics principle, extraneous cooling air enters vented cavity and turns to air ventilation resistance minimum when shunting at its runner turning, realized that the speed of a motor vehicle is because of changing the cooling air flow of the different direction that produces, size, all can enter the interior cooling cooling of vented cavity that disk body is interconnected swimmingly, obviously strengthen result of ventilating heat dissipation, improved the working life of brake disc effectively.
