Abstract
The utility model discloses a brake disc, and relates to the field of automobile devices. The brake disc is double-layered and ring-shaped; a plurality of heat dissipation ribs are arranged in the brake disc; the hollow part in the middle of the brake disc is a shaft hole; bolt holes are uniformly distributed in the periphery of the shaft hole; the heat dissipation ribs surround the shaft hole, and are spirally arranged at intervals; a plurality of arc grooves are formed in each heat dissipation rib; a diversion trench is formed between every two adjacent heat dissipation ribs. According to the brake disc provided by the utility model, the heat dissipation direction of the heat dissipation ribs is in accordance with the proceeding direction of wheels, an air inlet is enlarged, the direction of wind is changed through the diversion trenches formed between every two adjacent heat dissipation ribs, heat generated in braking can be emitted quickly, the temperature rising speed of a brake system in the braking can be slowed down, the generation of heat fading phenomenon can be delayed, and the braking distance is reduced.
Description
Technical field
The utility model relates to automotive fittings field, relates in particular to a kind of brake disc.
Background technique
In the device such as automobile, braking mechanism is the employing dish structure of stopping conventionally, and in braking process, brake disc is because of frictional heat, and temperature raises rapidly, can cause the friction factor of brake system to reduce, and causes heat fade phenomenon, causes braking distance to increase.Therefore the heat radiation of brake disc is the problem that is necessary consideration in optimization of vehicle design, for current brake disc, its main heat dissipation design is to dispel the heat by heat radiation rib, and heat radiation rib is generally strip, the sense of rotation of heat dissipation direction and wheel has certain angle, affects distributing in time of heat.
Model utility content
The utility model provides a kind of brake disc for overcoming the deficiency that in prior art, brake disc can not dispel the heat in time, and this brake disc has the feature of rapid heat dissipation.
A kind of brake disc, this brake disc is double-deck, and be circular, in brake disc, be provided with many heat radiation ribs, brake disc middle part hollow position is axis hole, and axis hole is evenly distributed with bolt hole around, and described heat radiation rib is spaced in the shape of a spiral around described axis hole, on heat radiation rib, be provided with multiple arc grooves, between described two adjacent heat radiation ribs, form guiding gutter.
Above-mentioned radiating fin bar quantity is 36～48.
The width of above-mentioned heat radiation rib is 5～7mm.
The radius of above-mentioned arc groove is 3～5mm.
The beneficial effects of the utility model: the brake disc that the utility model provides, the heat dissipation direction of its heat radiation rib is consistent with wheel direction of advance, strengthen intake grill, the guiding gutter forming by adjacent two radiating fin bars changes the direction of wind, the heat that when brake produces can be distributed rapidly, while slowing down brake, the warming velocity of brake system, delays the generation of heat fade phenomenon, has shortened braking distance.
Brief description of the drawings
Fig. 1 is the plan view of the utility model brake disc.
Fig. 2 is the schematic diagram of heat radiation rib of the present utility model.
Fig. 3 is radiating principle figure of the present utility model.
Fig. 4 is generalized section of the present utility model.
Embodiment
Now be described further the utility model by reference to the accompanying drawings in order better to illustrate.
As shown in Fig. 1 to 2, a kind of brake disc, this brake disc is double-deck, and be circular, be provided with many heat radiation ribs 1 in brake disc, brake disc middle part hollow position is axis hole 3, axis hole 3 is evenly distributed with bolt hole 2 around, described heat radiation rib 1 is spaced in the shape of a spiral around described axis hole 3, on heat radiation rib 1, is provided with multiple arc grooves 4, between described two adjacent heat radiation ribs 4, forms guiding gutter 5; Heat radiation rib 1 quantity is 36～48; The width of heat radiation rib 1 is 5～7mm; The radius of arc groove 4 is 3～5mm.
Article two, in the middle of adjacent heat radiation rib 1, can form guiding gutter 5, change the direction of wind.
As shown in Figs. 3-4, gas, along with heat radiation rib 1 rotates together, enters guiding gutter 5, then discharges through axis hole 3, and gas is exactly so continuously from wind, to be sucked into guiding gutter 5 and then continuously to discharge from axis hole 3 again.
In the process of braking automobile, brake disc rotates along with the rotation of tire, produce heat, the guiding gutter 5 of wind through forming between two adjacent heat radiation ribs 1, heat can be taken away by wind fast, and is provided with arc groove 4 on heat radiation rib, has increased the area of contact of wind with heat radiation rib 1, can take away more heat, brake disc can dispel the heat efficiently.
