The utility model discloses an automobile brake disc with through-holes and heat-dissipating and chip-removing grooves. The automobile brake disc comprises a brake surface and a brake disc body with a fixed interface. The brake surface comprises an upper brake surface and a lower brake surface, which are connected with the brake disc body, respectively. The automobile brake disc is characterized in that air holes and heat-dissipating and chip-removing grooves are formed on the brake surface in the tangential direction of the fixed interface; any one of the heat-dissipating and chip-removing grooves is positioned between two adjacent air holes; and any one of the air holes is positioned between two adjacent heat-dissipating and chip-removing grooves. The automobile brake disc with through-holes and heat-dissipating and chip-removing grooves can enhance the heat dissipation to prevent the problem of local overheat, reduce the brake noise, remove the oily dirt from the brake surface of the brake in time, and improve the braking effect.
Description
Technical field
The utility model relates to a kind of through hole heat radiation chip pocket automobile brake disc, especially a kind ofly bores through hole and the automobile brake disc that mills the heat radiation chip pocket at the brake disc face of stopping, and belongs to the automobile mechanical field.
Background technique
Along with the development of automotive industry over more than 100 year, the function of automobile is more and more perfect, and to the also raising thereupon of technical performance index requirement of itself, the braking of automobile is exactly one of very important technical performance index.Hyundai Motor is generally pursued at a high speed, and corresponding just the needs strengthened stopping power, how to resolve the automobile brake problem, is the manufacturing long-term problem of automobile and component thereof.
Automobile brake disc is in rotation status when using, we know because the size and Orientation of inertial force and inertia couple by Der Grundsatz der Maschinen, produce cyclically-varying along with the circulation of mechanical rotation, add that the distribution of the quality of automobile brake disc own and size are inhomogeneous, certainly will produce energy imbalance.When imbalance, will produce vibration, cause the braking ability and the reliability decrease of automobile when serious, when vibration frequency during, might cause resonance, and make damage of components, even jeopardize personal safety near system frequency.During braking automobile,, can produce a large amount of frictional heats, cause the automobile brake disc local superheating because of friction plate closely contacts without any the gap with automobile brake disc.If can not in time get rid of when surface of contact has greasy dirt, to reduce friction factor, will influence braking effect and brake system working life, even make friction plate and automobile brake disc temperature too high and produce distortion, damage, cause brake failure to cause traffic accident.
The model utility content
At the problem that prior art exists, technical problem to be solved in the utility model is that a kind of through hole heat radiation chip pocket automobile brake disc is provided, prevent the local superheating phenomenon to strengthen heat radiation, reduce brake noise, and in time get rid of the stop greasy dirt of face of automobile brake disc, improve braking effect.
For this reason, the technological scheme that through hole heat radiation chip pocket automobile brake disc of the present utility model is taked is, the brake disk body that it comprises the face of stopping and has fixed interface, the face of stopping comprises the face of stopping, the face of stopping down, it is connected with the brake disc disk body respectively, and especially the tangent direction at brake lining upper edge fixed interface is provided with vent hole and heat radiation chip pocket; All between two adjacent row's vent holes, arbitrary row's vent hole is all between two adjacent heat radiation chip pocket for any heat radiation chip pocket.Be processed with vent hole because brake disc is stopped on the face during brake, the local superheating phenomenon can not occur, radiating effect is better, and brake noise is obviously reduced, and when on brake disc is stopped face greasy dirt being arranged, can get rid of by chip pocket, thereby improve braking effect.
Above-mentioned through hole heat radiation chip pocket automobile brake disc, it is provided with 5-10 heat radiation chip pocket, and groove width is 3mm.
Above-mentioned through hole heat radiation chip pocket automobile brake disc, it is provided with 5-10 row vent hole, aperture 3mm.
The quantity of heat radiation chip pocket and vent hole is set according to the size of automobile brake disc, the face width of stopping degree.General groove is got 5-10, and groove width is 3mm, and processing tangentially can reduce harmful friction of groove and friction plate, increase friction plate working life.5-10 row is generally bored in the hole, 3 of every rows, and bore dia is got 3mm, and diameter is crossed conference influences brake disc intensity, and too small being unfavorable for ventilates.
The claimant has done finite element analysis and actual tests, increases the boring and the groove of some on brake disc is stopped face, can any negative effect not arranged to automobile.Through hole heat radiation chip pocket automobile brake disc, owing on the face of stopping up and down, increased the through hole and the groove of some, compare with general common disk, the face wear-resisting property of stopping improves 50%, heat dispersion improves 50%, kept original compressive strength, and, had stability preferably because of good processability.
Through hole heat radiation chip pocket automobile brake disc is applicable to car, station wagon, High Speed Light truck, multifunctional movement car etc., belongs to the New Product of one of vehicle key component.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of the utility model through hole heat radiation chip pocket automobile brake disc;
Fig. 2 is the sectional view of through hole heat radiation chip pocket automobile brake rim axis.
