Abstract
The utility model relates to an improve quotation heat dispersion's brake disc comprises flange face, braking quotation and dish neck, and the braking quotation comprises inside and outside braking quotation, and many diametric connection muscle of equipartition between the inside and outside braking quotation form heat dissipation channel between two adjacent diametric connection muscle, its characterized in that: evenly be equipped with the louvre that the multiunit axial runs through in the braking quotation, the louvre communicates with each other with corresponding heat dissipation channel, and the diameter of every group louvre decreases progressively along braking quotation outside -in in proper order. Its is rational in infrastructure, the radiating effect good, long service life.
Description
Technical field
The utility model relates to the brake disc of vehicle disc brake, and particularly a kind of brake disc improving card heat dispersion, is mainly applicable to heavy truck or light truck.
Background technique
Brake disc (i.e. brake disc) is that one is fixed on wheel hub, for realizing with brake caliper acting in conjunction the device that brakes, belongs to the vital part in brake assembly.Existing brake disc is made up of flanged surface, brake disk surface, the dish neck be connected between flanged surface and brake disk surface, wherein, flanged surface is provided with the tapped hole for being connected with wheel hub, and brake disk surface is made up of inside and outside brake disk surface, is provided with connecting tendon between inside and outside brake disk surface.But the brake disk surface surface-closed of existing brake disc, heat dispersion is poor, when braking brake disk surface and brake caliper severe friction, produce a large amount of heat energy, owing to can not timely and effectively dispel the heat, cause brake disk surface to produce heat fade, card ftractures, and has a strong impact on the working life of brake disc.
Model utility content
The purpose of this utility model is the brake disc of the improvement card heat dispersion in order to provide a kind of rational in infrastructure, good heat dissipation effect, the long service life that solve the problem.
The technical solution of the utility model is:
A kind of brake disc improving card heat dispersion, be made up of flanged surface, brake disk surface and dish neck, brake disk surface is made up of inside and outside brake disk surface, uniform many radial connecting tendons between inside and outside brake disk surface, heat dissipation channel is formed between two adjacent radial connecting tendons, it is characterized in that: described brake disk surface is evenly provided with the radiation hole that many groups axially run through, described radiation hole communicates with corresponding heat dissipation channel, and the diameter often organizing radiation hole successively decreases successively along brake disk surface ecto-entad.
The brake disc of above-mentioned improvement card heat dispersion, the shape of described radiation hole is circular.
The brake disc of above-mentioned improvement card heat dispersion, described radiation hole divides three groups, with brake disc shaft axis for symmetry center is evenly distributed in brake disk surface, often organizes radiation hole and divides three row five to arrange fan-shaped distribution.
The brake disc of above-mentioned improvement card heat dispersion, described flanged surface is evenly equipped with multiple flange hole.
The beneficial effects of the utility model are:
1, compared with existing brake disc, organize radiation hole owing to arranging more, make brake disk surface no longer be in air-tight state, significantly improve the heat dispersion of brake disk surface, enhance radiating effect, extend the working life of brake disc;
2, owing to brake disk surface being evenly provided with the radiation hole that many groups axially run through, instead of be covered with brake disk surface, so do not affect the intensity of brake disk surface, also mitigate the weight of brake disk surface simultaneously, be conducive to Product transport;
3, for adapting to heat dissipation channel structure wide outside and narrow inside, the diameter often organizing radiation hole successively decreases successively along brake disk surface ecto-entad, and structural design is more reasonable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 be in Fig. 1 A-A to sectional drawing.
In figure: 1. outer brake disk surface, 2. radiation hole, 3. radial connecting tendon, 4. dish neck, 5. flanged surface, 6. flange hole, 7. inside brake card, 8. heat dissipation channel.
Embodiment
As shown in the figure, the brake disc of this improvement card heat dispersion, be made up of flanged surface 2, brake disk surface and dish neck 4, brake disk surface is made up of inside and outside brake disk surface 7,1, uniform many radial connecting tendons 3 between inside and outside brake disk surface 7,1, heat dissipation channel 8 is formed between adjacent two radial connecting tendons 3, described brake disk surface is evenly provided with the radiation hole 2 that many groups axially run through, described radiation hole 2 communicates with corresponding heat dissipation channel 8, and the diameter often organizing radiation hole 2 successively decreases successively along brake disk surface ecto-entad.In the present embodiment, radiation hole 2 is formed by machining, and shape is circular, is divided into three groups, with brake disc shaft axis for symmetry center is evenly distributed in brake disk surface, often organizes radiation hole 2 point of three row five and arrange fan-shaped distribution.Described flanged surface 5 is evenly equipped with the multiple flange holes 6 for being connected with wheel hub.
Prove by experiment: the brake disc adopting the application, by increasing radiation hole 2, its heat dissipation potential improves 30%-40%, when brake disc service condition is constant, in braking process, when brake caliper take-off the brake dish, air forms convection current, and a heat energy part is exhaled fast by radiation hole 2, reduce the hydraulic performance decline that heat fade causes, usability improves greatly, it can be said that bright, and the brake disc of the application has good heat dissipation potential.
Claims (4)
1. one kind is improved the brake disc of card heat dispersion, be made up of flanged surface, brake disk surface and dish neck, brake disk surface is made up of inside and outside brake disk surface, uniform many radial connecting tendons between inside and outside brake disk surface, heat dissipation channel is formed between two adjacent radial connecting tendons, it is characterized in that: described brake disk surface is evenly provided with the radiation hole that many groups axially run through, described radiation hole communicates with corresponding heat dissipation channel, and the diameter often organizing radiation hole successively decreases successively along brake disk surface ecto-entad.
