Abstract
The utility model relates to the automobile brake disc technical field, in particular to an automobile magnalium ceramic brake disc, which solves the problems of bad abrasion resistance, bad radiating effect, large mass and so on of the prior cast iron brake disc. The utility model comprises an annular disc body and a convex cylinder, wherein, the annular disc body is formed by die casting of magnalium on the whole; a magnesia ceramic abrasion resistant layer is arranged on the friction surface of the annular disc body and can be fabricated by adoption of spray coating techniques or micro arc oxidation techniques, thereby the utility model has the advantages of great improvement of performances like abrasion resistance, high-temperature resistance and so on, good radiating effect which is over four times quicker than the cast iron brake disc, prolonging of service life of the brake disc, braking performance which is far higher than that of the prior cast iron brake disc, and friction service life which is over four times higher than that of the prior cast iron brake disc. Moreover, mass of the utility model is 40 to 50 percent of the prior cast iron brake disc, thereby fuel consumption of a whole vehicle is reduced. The brake disc of the utility model can be widely applied in various miniature cars.
Description
Technical field
The utility model relates to the automobile brake disc technical field, is specially a kind of automobile magnalium Ceramic Disc Brakes.
Background technique
Brake system of car divides by type, mainly is divided into two kinds of drum brake and disc type brakes.Drum brake utilizes brake shoe extruding brake drum to produce that braking force stops, and causes reasons such as moment brake failure, heat radiation be bad behind bad owing to its braking force smoothness, the wet water easily, begins gradually to be eliminated by auto manufacturing, belongs to backward technology.Present main flow braking system is a disk type braker, mainly constitute by brake disc and a pair of braking plate, wherein brake disc and wheel connect, braking plate and brake cylinder are fixed, and are used for clamping brake disc, when driver's pin is stepped on brake petal, pedal promotes braking overall pump promotion hydraulic oil and enters wheel cylinder, the hydraulic pressure that the piston of wheel cylinder is transported by oil pipe, the promotion braking plate is pressed to brake disc and is rubbed, and produces braking force and stops to force wheel.In said system, brake disc is a vitals, and at present great majority all are to be made by cast iron, have following problem in actual applications, 1, wear no resistance, and wear intensity is higher; 2, radiating effect is bad, steps on repeatedly will cause brake disc to be heated after the braking and its temperature is risen to more than 350 degree, causes friction factor to reduce, and stopping distance prolongs, braking failure, and accident takes place frequently; 3, quality is big, has increased the fuel consumption of car load, and Cast Iron Surface very easily gets rusty, in a word cast iron brake disk short, poor stop in working life.
Summary of the invention
The utility model provides a kind of automobile magnalium Ceramic Disc Brakes in order to solve problems such as existing cast iron brake disk wears no resistance, radiating effect is bad, quality is big.
The utility model is to adopt following technological scheme to realize: automobile magnalium Ceramic Disc Brakes, comprise the circular disk body, be connected in the convex cylinder at circular disk body center, have through hole on the boss of convex cylinder upper-end surface, described circular disk body is to be formed by magnalium die casting on the whole, and the rubbing surface of circular disk body is provided with ceramic wearing coat.The compression molding process of circular disk body described in the utility model is that those of ordinary skill in the art is easy to realize for existing known technology.Compare with the brake disc of existing cast iron quality, the circular disk body that the utility model adopts magnalium to make, weight alleviates greatly, thereby has reduced the fuel consumption of car load; And on rubbing surface, set up ceramic wearing coat, and because characteristics such as itself that pottery has is wear-resisting, high temperature resistant, hardness height,, prolonged the working life of brake disc so improved the performance such as wear-resisting, high temperature resistant of brake disc, strengthened the braking safety of car load.
Described ceramic wearing coat is the magnesia ceramics wearing layer, the magnesia ceramics wearing layer can adopt spraying coating process to make, also can adopt the micro-arc oxidation process oxidation to form, principle, the technology of described spraying equipment, spraying method and differential arc oxidation belong to known technology, are that those of ordinary skill in the art knows.
The thickness of described ceramic wearing coat is 0.5-1mm.
Compared with prior art, the utility model is with full annular disc magnalium die cast, and the magnesia ceramics wearing layer is set on rubbing surface, improved the performance such as wear-resisting, high temperature resistant of brake disc greatly, radiating effect is good, prolonged the working life of brake disc, braking ability is higher than traditional cast iron brake disk far away, and weight is lighter, alleviated the weight of wheel greatly, only be the 40-50% of existing cast iron brake disk, reduced the fuel consumption of car load, brake disc described in the utility model can be widely used in various types of automobiles.
