A kind of heat-dissipation brake disc
Technical field
This utility model relates to brake system of car technical field, in particular to a kind of heat-dissipation brake disc.
Background technology
Automotive disc brake is also called disc brake, and it is by hydraulic control, and main parts size has brake disc, wheel cylinder, caliper, oil pipe etc..Alloy steel for braking discs manufacture is also fixed on wheel, with vehicle wheel rotation.But existing brake disc friction surface temperature when braking drastically raises, and produces substantial amounts of heat, and this is accomplished by brake disc and has high thermal capacity and good radiating effect.
Utility model content
The purpose of this utility model is to provide a kind of heat-dissipation brake disc, to solve deficiency of the prior art.
For realizing this utility model purpose, the technical scheme of employing is:
A kind of heat-dissipation brake disc, including: annular disk body that cylinder is connected with cylinder periphery, the friction plate that is positioned at annular disk body both sides, it is characterized in that: in described annular disk body two card, be provided with some dowels, and dowel circumference is evenly distributed on annular disk body;Described dowel is arc line shaped, and the gap between adjacent two dowels forms ventilating duct;Described friction plate is provided with heat abstractor in ventilating duct;Described heat abstractor includes the protection network being positioned at ventilating duct, and protection network is provided with rotating shaft, and rotating shaft is provided with fan blade;Ventilating duct sectional area at the external disc of described annular disk is more than the ventilating duct sectional area of annular disk body center;The friction plate of both sides is separately fixed on the dowel of annular disk body two card, and the external diameter of friction plate is more than the external diameter of annular disk body;The periphery of described friction plate is provided with garland;The work surface of described friction plate offers along the axial equally distributed multiple dedusting grooves of friction plate;The work surface of described friction plate is provided with multiple wear-resistant block.
The beneficial effects of the utility model are,
One, the ventilating duct between dowel is arc-shaped structure, the sectional area of ventilating duct is from the external disc of annular disk to annular disk body center from large to small, ventilating duct is tangent with annular disk body radially cylindrical, this outer cut camber line ventilating duct produces the wind speed of flowing, the amount of heat produced when quickly taking away friction disc brake when can efficiently utilize running car.
Two, two friction plate external diameters are more than the external diameter of annular disk body, make to be formed between two friction plates cannelure, when disc rotation, make the air flow faster in cannelure, thus speed air flow in further speeding up ventilating duct, it is achieved combustion thermal effect.
Three, by set garland, the hydrops on friction plate can be got rid of such that it is able to keep the cleaning of friction plate, improve braking effect, extend the service life of friction plate.Arranging of wear-resistant block can reduce the frictional dissipation that friction is unilateral, improves the service life of friction plate.
Four, during braking, fricative powder drops to multiple dedusting groove, due to centrifugal action, quickly the powder in dedusting groove can be dished out, further reduce the dust attachment in Friction Disk Surface, will not skid because of powder during high-speed friction, make braking quality more stable, thus extend the service life of friction plate.By the protection network being arranged in ventilating duct, the infringement to fan blade of the vehicle introduced contaminants under steam can be prevented, and vehicle is travelling or during brake, fan blade all can high speed rotating, accelerate the air circulation in ventilating duct, thus add the radiating rate of brake disc.
Accompanying drawing explanation
Fig. 1 is the structural representation of the heat-dissipation brake disc that this utility model provides;
Fig. 2 is the structural representation of ventilating duct;
Fig. 3 is the front view of heat-dissipation brake disc;
Fig. 4 is the structural representation of heat abstractor.
Detailed description of the invention
Below by specific embodiment and combine accompanying drawing this utility model is described in further detail.
The heat-dissipation brake disc of this utility model offer that Fig. 1-4 is shown, including friction plate 2, dowel 3, cylinder 4, installing hole 5, heat abstractor 8, ventilating duct 7, wear-resistant block 10, dedusting groove 11, protection network 81, garland 14, annular disk body 13, fan blade 82 and rotating shaft 83.Described cylinder is provided with equally distributed installing hole 5;Cylinder 4 periphery connect annular disk body 13, be positioned at annular disk body 13 both sides friction plate 2;It is provided with some dowels 3 in described annular 13 liang of cards of disk body, and dowel 3 circumference is evenly distributed on annular disk body 13;Described dowel 3 is arc line shaped, and the gap between adjacent two dowels 3 forms ventilating duct 7;Described friction plate 2 is provided with heat abstractor 8 in ventilating duct 7;Described heat abstractor 8 includes the protection network 81 being positioned at ventilating duct 7, and protection network 81 is provided with rotating shaft 83, and rotating shaft 83 is provided with fan blade 82;Ventilating duct sectional area at described annular disk body 13 periphery is more than the ventilating duct sectional area of annular disk body 13 center;The friction plate 2 of both sides is separately fixed on the dowel of annular 13 liang of cards of disk body, and the external diameter of friction plate 2 is more than the external diameter of annular disk body 13;The periphery of described friction plate 2 is provided with garland 14;The work surface of described friction plate 2 offers along the axial equally distributed multiple dedusting grooves 11 of friction plate 2;The work surface of described friction plate 2 is provided with multiple wear-resistant block 10.
Ventilating duct 7 between dowel 3 is arc-shaped structure, the sectional area of ventilating duct 7 is from annular disk body 13 periphery to annular disk body 13 center from large to small, ventilating duct 7 is tangent with annular disk body 13 radially cylindrical, this outer cut camber line ventilating duct 7 produces the wind speed of flowing, the amount of heat produced when quickly taking away friction disc brake when can efficiently utilize running car.
