Rust-proof and wear-resistant automobile brake disc

Abstract

The utility model discloses a rust-proof wear-resistant automobile brake disc which comprises a disc body I and a disc body II, a plurality of ribs are fixed between the disc body I and the disc body II, and the ribs are annularly arrayed between the disc body I and the disc body II at equal intervals. When air flows into the cavity in the braking process, the air can be blown to the heat dissipation fins to dissipate heat of the heat dissipation fins, and due to the fact that the first distance between the heat conduction piece and the air guide plate is gradually reduced in the direction from the outer ring of the first disc body to the inner ring of the first disc body, the speed is higher and higher when the air circulates in the first distance; when the air circulates in the first space, the second space between the adjacent heat dissipation fins is gradually reduced in the direction from the outer ring of the first disc body to the inner ring of the first disc body, so that the heat dissipation speed is increased, and the heat dissipation efficiency is improved. And the air circulation speed is further increased, the heat dissipation speed is further increased, and therefore the abrasion resistance of the brake disc is improved.

Description

Technical Field

[0001] This utility model relates to the field of automotive brake disc technology, and in particular to a rust-proof and wear-resistant automotive brake disc. Background Technology

[0002] Simply put, a brake disc is a round plate that rotates when the car is moving. The brake caliper clamps the brake disc to generate braking force. When you press the brake pedal, it is the caliper that clamps the brake disc to slow down or stop the car.

[0003] Publication No. CN 222296815 U discloses a rust-proof and wear-resistant brake disc. By setting a third coating material of quartz powder, the wear resistance of the friction disc is improved. When the friction disc is in use, heat is introduced into the first heat-conducting plate through the second heat-conducting plate, and then conducted to the surface of the aluminum square tube through the first heat-conducting plate. Since the aluminum square tube is hollow, air flow will be formed inside the aluminum square tube when the car is running, thereby cooling the surface of the aluminum square tube and completing the heat dissipation of the brake disc.

[0004] The aforementioned prior art uses epoxy resin as the fourth coating material, inositol hexaphosphate as the first coating material, and polytetrafluoroethylene as the second coating material to provide corrosion protection for the second and first heat-conducting discs. Although this provides rust prevention, it only increases wear resistance by spraying quartz powder. In reality, the wear resistance of the brake disc is closely related to its heat dissipation. When the brake disc is working, it generates resistance through friction with the brake pads, converting the vehicle's kinetic energy into heat energy to achieve vehicle deceleration and stopping. During frequent braking operations, brake discs generate a large amount of heat. If the heat dissipation performance is poor, the brake discs will be in a high-temperature state. High temperatures will accelerate the wear of the brake disc material, reduce its hardness and strength, and make the brake discs more prone to wear. When the brake disc temperature reaches a certain level, both the brake pads and the brake disc will experience thermal fade. Thermal fade will reduce the braking force. In order to achieve the same braking effect, the driver may increase the braking force, which further increases the friction between the brake pads and the brake disc, thereby aggravating the wear of the brake disc. Currently, brake discs usually rely on ventilation holes on the brake disc for heat dissipation. However, this method still relies solely on air contact with the brake disc for heat dissipation, and the heat dissipation area is limited, resulting in unsatisfactory heat dissipation. Utility Model Content

[0005] (a) Purpose of the utility model

[0006] In view of this, the purpose of this utility model is to propose a rust-resistant and wear-resistant automotive brake disc. The technical problem it aims to solve is that the wear resistance and heat dissipation of the brake disc are closely related. When the brake disc is working, it generates resistance through friction with the brake pads, converting the vehicle's kinetic energy into heat energy to achieve vehicle deceleration and stopping. During frequent braking operations, the brake disc generates a large amount of heat. If the heat dissipation performance is poor, the brake disc will be in a high-temperature state. High temperature will accelerate the wear of the brake disc material, reduce its hardness and strength, and make the brake disc more susceptible to wear. When the brake disc temperature reaches a certain level, both the brake pads and the brake disc will experience thermal fade. Thermal fade will reduce the braking force. To achieve the same braking effect, the driver may increase the braking force, which further increases the friction between the brake pads and the brake disc, thus aggravating the wear of the brake disc. Currently, brake discs usually rely on ventilation holes on the brake disc for heat dissipation, but this method still relies solely on air contact with the brake disc for heat dissipation. The heat dissipation area is limited, and the heat dissipation effect is not ideal.

[0007] (II) Technical Solution

[0008] To achieve the above technical objectives, this utility model provides a rust-resistant and wear-resistant automotive brake disc:

[0009] It includes a disk body one and a disk body two. Multiple ribs are fixed between disk body one and disk body two. The multiple ribs are arranged in a ring with equal spacing between disk body one and disk body two. The multiple ribs divide the gap between disk body one and disk body two into multiple chambers. Two heat-conducting plates are arranged in each of the multiple chambers. The two heat-conducting plates are fixed to disk body one and disk body two respectively. Two air guide plates are arranged between the two heat-conducting plates. A connecting plate is fixed to one side of the two air guide plates. Multiple heat dissipation fins are fixed to the side of the two heat-conducting plates that are close to each other. The side of the multiple heat dissipation fins that are away from the heat-conducting plates is fixed to the corresponding air guide plate.

[0010] Preferably, both the first and second disk bodies are provided with multiple heat dissipation holes, and each of the multiple heat-conducting sheets is provided with multiple through holes, which are respectively connected to the corresponding heat dissipation holes.

[0011] Preferably, there is a gap of one between the two air guide plates on the side that is far apart from each other and the corresponding heat conduction plate, and there is a gap of two between adjacent heat dissipation fins among the plurality of heat dissipation fins.

[0012] Preferably, the size of the spacing gradually decreases from the outer ring of the disk body to the inner ring of the disk body.

[0013] Preferably, the size of the second spacing gradually decreases from the outer ring of the disk body to the inner ring of the disk body.

[0014] Preferably, a shaft head is fixed to one side of the disc body, and the shaft head has multiple mounting holes.

[0015] As can be seen from the above technical solutions, this application has the following beneficial effects:

[0016] 1. Both disc body one and disc body two are coated with an anti-rust layer. This anti-rust layer can be polytetrafluoroethylene or inositol hexaphosphate, which can prevent rust on disc body one and disc body two. In addition, through the setting of heat conduction plate and heat dissipation fin, when braking, the heat conduction plate can conduct heat from disc body one and disc body two to heat dissipation fin, and the heat dissipation fin increases the heat dissipation area, thereby increasing the heat dissipation efficiency and improving its wear resistance.

[0017] 2. When braking, air flows into the brake chamber and blows towards the cooling fins to dissipate heat. As the distance between the heat-conducting fins and the air guide plate gradually decreases from the outer ring of the brake disc to the inner ring, the airflow speed increases within this distance. This results in a greater amount of air flowing over the surface of the cooling fins and heat-conducting fins per unit time. More airflow can carry away more heat more quickly, thus accelerating the heat dissipation speed. Furthermore, as air flows within this distance, the distance between adjacent cooling fins also gradually decreases from the outer ring of the brake disc to the inner ring, further increasing the airflow speed and accelerating the heat dissipation speed. This increased heat dissipation speed improves the wear resistance of the brake disc. Attached Figure Description

[0025] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0026] Reference Figure 1-5 :

[0027] In one embodiment of this utility model, a rust-proof and wear-resistant automotive brake disc is provided, comprising a disc body 1 and a disc body 2. A shaft head 13 is fixed to one side of the disc body 1, and a plurality of mounting holes 14 are provided in the shaft head 13. A plurality of ribs 3 are fixed between the disc body 1 and the disc body 2, and the plurality of ribs 3 are arranged in a ring with equal spacing between the disc body 1 and the disc body 2. The plurality of ribs 3 divide the gap between the disc body 1 and the disc body 2 into a plurality of chambers 4. Two heat-conducting plates 5 are provided in each of the plurality of chambers 4. The two heat-conducting plates 5 are fixed to the disc body 1 and the disc body 2 respectively. Two air guide plates 6 are provided between the two heat-conducting plates 5. A connecting plate 7 is fixed to one side of the two air guide plates 6. A plurality of heat dissipation fins 8 are fixed to the side of the two heat-conducting plates 5 that are close to each other. The side of the plurality of heat dissipation fins 8 that is away from the heat-conducting plates 5 is fixed to the corresponding air guide plate 6.

[0028] It should be noted that the outer surfaces of disc body 1, disc body 2, and shaft head 13 are all coated with an anti-rust layer. This anti-rust layer can be polytetrafluoroethylene or inositol hexaphosphate, thus providing rust protection for disc body 1, disc body 2, and shaft head 13. Furthermore, through the arrangement of heat-conducting plates 5 and heat dissipation fins 8, when braking, the heat-conducting plates 5 can conduct heat from disc body 1 and disc body 2 to the heat dissipation fins 8. The heat dissipation fins 8 increase the heat dissipation area, thereby increasing heat dissipation efficiency and improving wear resistance. The main reason is that during frequent braking operations, the brake disc generates a large amount of heat. If the heat dissipation performance is poor, the brake disc will be at a high temperature, which will accelerate the wear of the brake disc material and reduce its hardness. The high temperature and strength of brake discs make them more prone to wear. When the brake disc temperature reaches a certain level, both the brake pads and the brake disc will experience thermal fade. Thermal fade weakens the braking force. To achieve the same braking effect, the driver may increase the braking force, which further increases the friction between the brake pads and the brake disc, thus aggravating the wear of the brake disc. Therefore, current brake discs usually rely on ventilation holes on the brake disc for heat dissipation. However, this method still relies solely on air contact with the brake disc for heat dissipation, and the heat dissipation area is limited, resulting in unsatisfactory heat dissipation. This device increases the heat dissipation area by adding multiple heat-conducting fins 5 and heat dissipation fins 8, thereby improving the heat dissipation effect and thus improving the wear resistance of the brake disc.

[0029] Specifically, multiple heat dissipation holes 9 are provided in both disk body 1 and disk body 2, and multiple through holes 10 are provided in each of the multiple heat-conducting plates 5. The multiple through holes 10 are connected to the corresponding heat dissipation holes 9. There is a gap 11 between the two air guide plates 6 on the side that is far apart from each other and the corresponding heat-conducting plate 5. There is a gap 22 between two adjacent heat dissipation fins 8. The size of the gap 11 gradually decreases from the outer ring of disk body 1 to the inner ring of disk body 1, and the size of the gap 22 gradually decreases from the outer ring of disk body 1 to the inner ring of disk body 1.

[0030] It should be noted that when braking, air flows into the chamber 4 and blows towards the cooling fins 8 to dissipate heat. As the distance 11 between the heat-conducting fins 5 and the air guide plate 6 gradually decreases from the outer ring of the disc body 1 to the inner ring, the airflow speed increases within the distance 11. This increases the amount of air flowing over the surface of the cooling fins 8 and the heat-conducting fins 5 per unit time. More airflow can carry away more heat more quickly, thus accelerating the heat dissipation speed. As airflow occurs within the distance 11, the distance 212 between adjacent cooling fins 8 also gradually decreases from the outer ring of the disc body 1 to the inner ring, further increasing the airflow speed and accelerating the heat dissipation speed. This increased heat dissipation speed improves the wear resistance of the brake disc.

[0031] The exemplary implementation of the solution proposed in this disclosure has been described in detail above with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
