Description

Technical Field

[0001] The utility model relates to the technical field of brake discs, and more specifically, to a porous heat-dissipating and high-strength brake disc for bicycles. Background Art

[0002] Most brake discs are made of stainless steel. However, stainless steel is not only heavy but also has poor thermal conductivity. When a bicycle is in motion, it needs to brake frequently, generating a large amount of heat. If this heat cannot be dissipated in time, "heat exhaustion" will occur, resulting in a decline in braking performance. If stainless steel is not used as the material, the hardness of general metal materials cannot meet the requirements of braking. Therefore, it is necessary to combine and match brake discs. In existing combined brake discs, most have a large number of holes and grooves inside the brake disc, resulting in poor supporting strength, so there may be a situation of insufficient supporting strength. Summary of the Utility Model

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a porous heat-dissipating and high-strength brake disc for bicycles, which has the advantages of good heat dissipation effect and sufficient supporting force.

[0004] To achieve the above object, the utility model provides the following technical solution: A porous heat-dissipating and high-strength brake disc for bicycles, comprising: a brake disc, a fixing groove is opened inside the brake disc, a heat sink is fixedly installed inside the fixing groove, a first installation groove is opened inside the heat sink, a copper sheet is fixedly installed inside the first installation groove, a ventilation groove is opened inside the heat sink, and the ventilation groove is located in the middle of the heat sink; an installation hole, the installation hole is located inside the brake disc, a positioning shaft groove and a second installation groove are opened inside the brake disc, a heat dissipation strip is fixedly installed inside the second installation groove, and the second installation groove is circular.

[0005] The beneficial effect of adopting the above technical solution is: The diameter value of the heat dissipation strip is greater than the diameter value of the positioning shaft groove. Its main function is to improve the overall thermal conductivity of the brake disc. When more heat is generated, it can be discharged in time. At the same time, the heat sink increases its heat dissipation effect. At the same time, the mass of the heat sink is lighter than that of the brake disc, which can play a certain supporting effect while ensuring the heat dissipation effect.

[0006] As a preferred technical solution of the utility model, ventilation holes are opened inside the brake disc, there are multiple ventilation holes, and the multiple ventilation holes are located outside the fixing groove.

[0007] The beneficial effect of adopting the above technical solution is: The main function of the multiple ventilation holes is to reduce the overall weight of the brake disc and improve the ventilation effect of the brake disc, so that the brake disc ensures the overall supporting strength while reducing a certain weight.

[0008] As a preferred technical solution of the present utility model, anti-slip particles are fixedly installed on both the front and rear sides of the brake disc. There are multiple anti-slip particles, and multiple anti-slip particles are all located in the middle of the two ventilation holes.

[0009] The beneficial effects of adopting the above technical solution are: The main function of multiple anti-slip particles is to increase the friction between the brake disc and the brake components, thereby increasing the wear resistance at the edge of the brake disc and improving the braking effect.

[0010] As a preferred technical solution of the present utility model, the positioning shaft groove is coaxial with the brake disc, and the outer side of the positioning shaft groove is irregular. The diameter value of the positioning shaft groove is smaller than the diameter value of the second installation groove.

[0011] The beneficial effects of adopting the above technical solution are: The positioning shaft groove is fixed to the central shaft of the bicycle wheel, making the overall installation of the brake disc convenient. And because the positioning shaft groove is irregular, it will not rotate automatically after being fixed to the axle, thus maintaining the braking effect.

[0012] As a preferred technical solution of the present utility model, there are multiple installation holes. Multiple installation holes are all located outside the positioning shaft groove, and multiple installation holes are all circular.

[0013] The beneficial effects of adopting the above technical solution are: The main function of multiple installation holes is to reinforce the installation of the brake disc, improve the stability of the brake disc installation, and increase the overall stress intensity of the brake disc during braking.

[0014] As a preferred technical solution of the present utility model, there are four fixing grooves. Four fixing grooves are all located outside the heat dissipation strips. There are four heat dissipation fins, and four heat dissipation fins are respectively located inside the four fixing grooves.

[0015] The beneficial effects of adopting the above technical solution are: The four fixing grooves are elliptical in shape, increasing the overall aesthetic appearance of the brake disc. At the same time, the material of the four heat dissipation fins is aluminum alloy with a relatively low density. In addition to reducing the overall weight, the overall support of the brake disc is ensured.

[0016] As a preferred technical solution of the present utility model, there are multiple first installation grooves. Multiple first installation grooves are respectively located inside the four heat dissipation fins, and multiple first installation grooves are respectively located on the front and rear sides of the brake disc. There are multiple copper sheets.

[0017] The beneficial effects of adopting the above technical solution are: The material of multiple copper sheets has strong heat conductivity. When the brake disc is subjected to long-term braking friction, a large amount of heat will be generated on the surface of the brake disc. Since the heat conductivity of the brake disc itself is poor, the heat is timely transported outward through multiple copper sheets to achieve the effect of rapid heat dissipation.

[0018] As a preferred technical solution of the present utility model, there are multiple ventilation grooves, and all of the multiple ventilation grooves are located outside the heat sink, and all of the multiple ventilation grooves are located on the front and rear sides of the heat sink.

[0019] The beneficial effects of adopting the above technical solution are as follows: The main function of the multiple ventilation grooves is to improve the ventilation effect on both sides of the copper sheet after the copper sheet is thermally conducted, timely increase the heat dissipation channels, achieve the effect of quickly cooling the copper sheet, so that the brake disc can also have the effect of quickly dissipating heat after being braked for a long time, and improve the overall service life of the brake disc.

When more heat is generated, it can be discharged in time. At the same time, the heat sink 3 increases its heat dissipation effect. At the same time, the mass of the heat sink 3 is lighter than that of the brake disc 1, and it can play a certain supporting effect while ensuring the heat dissipation effect.

[0029] Among them, ventilation holes 10 are opened inside the brake disc 1, there are multiple ventilation holes 10, and the multiple ventilation holes 10 are located outside the fixing groove 2.

[0030] The beneficial effects of adopting the above technical solution are: the main function of the multiple ventilation holes 10 is to reduce the overall weight of the brake disc 1 and improve the ventilation effect of the brake disc 1, so that the brake disc 1 ensures the overall supporting strength while reducing a certain weight.

[0031] Among them, anti-slip particles 11 are fixedly installed on both the front and rear sides of the brake disc 1, there are multiple anti-slip particles 11, and the multiple anti-slip particles 11 are all located in the middle of two ventilation holes 10.

[0032] The beneficial effects of adopting the above technical solution are: the main function of the multiple anti-slip particles 11 is to increase the friction between the brake disc 1 and the brake components, thereby increasing the wear resistance at the edge of the brake disc 1 and improving the braking effect.

[0033] Among them, the positioning shaft groove 12 is coaxial with the brake disc 1, and the outer side of the positioning shaft groove 12 is irregular, and the diameter value of the positioning shaft groove 12 is smaller than the diameter value of the second installation groove 8.

[0034] The beneficial effects of adopting the above technical solution are: the positioning shaft groove 12 is fixed to the central shaft of the bicycle wheel, making the overall installation of the brake disc 1 convenient. And because the positioning shaft groove 12 is irregular, it will not rotate automatically after being fixed to the axle, thus maintaining the braking effect.

[0035] Among them, there are multiple mounting holes 7, the multiple mounting holes 7 are all located outside the positioning shaft groove 12, and the multiple mounting holes 7 are all circular.

[0036] The beneficial effects of adopting the above technical solution are as follows: The main function of the multiple mounting holes 7 is to reinforce the installation of the brake disc 1, improve the stability of the installation of the brake disc 1, and increase the overall stress intensity of the brake disc 1 during braking.

[0037] Among them, there are four fixing grooves 2, and the four fixing grooves 2 are all located outside the heat dissipation strips 9. There are four heat dissipation fins 3, and the four heat dissipation fins 3 are distributed inside the four fixing grooves 2.

[0038] The beneficial effects of adopting the above technical solution are as follows: The four fixing grooves 2 are elliptical in shape, which increases the overall aesthetic appearance of the brake disc 1. At the same time, the four heat dissipation fins 3 are made of aluminum alloy with a relatively low density. In addition to reducing the overall weight, the overall support of the brake disc 1 is ensured.

[0039] Among them, there are multiple first installation grooves 4. The multiple first installation grooves 4 are respectively located inside the four heat dissipation fins 3, and the multiple first installation grooves 4 are respectively located on the front and back sides of the brake disc 1. There are multiple copper sheets 5.

[0040] The beneficial effects of adopting the above technical solution are as follows: The multiple copper sheets 5 are made of materials with strong thermal conductivity. When the brake disc 1 is subjected to long-term braking friction, a large amount of heat will be generated on the surface of the brake disc 1. Since the brake disc 1 itself has poor thermal conductivity, the multiple copper sheets 5 are used to timely transfer the heat outward to achieve the effect of rapid heat dissipation.

[0041] Among them, there are multiple ventilation grooves 6. The multiple ventilation grooves 6 are all located outside the heat dissipation fins 3, and the multiple ventilation grooves 6 are all located on the front and back sides of the heat dissipation fins 3.

When the brake disc 1 is braking, the overall stress of the brake disc 1 can be effectively improved;

[0045] Meanwhile, when long-term braking is required, the braking assembly will rub against the outer ring of the brake disc 1 to brake the bicycle. During the friction process, a large amount of heat will be generated. When a large amount of heat accumulates and is not dissipated, it will affect the overall service life of the brake disc 1. At this time, since the heat sink 3 is fixedly installed inside the brake disc 1, and the copper sheet 5 is fixedly installed inside the heat sink 3, and the heat sink 3 is made of aluminum alloy and the copper sheet 5 is made of copper, which has good supporting performance and thermal conductivity, thus improving the overall heat conduction effect of the brake disc 1 and the overall service life.

[0046] Meanwhile, since anti-slip particles 11 are fixedly installed on both the front and rear sides of the brake disc 1, the anti-slip particles 11 improve the overall friction between the brake disc 1 and the braking device, thereby making the braking performance higher and achieving a better braking effect.
