Description

Technical Field

[0001] The utility model relates to the technical field of brake pads, in particular to a brake pad abrasive composite coating structure. Background Art

[0002] Currently, brake pads are only grooved and beveled at the grinding material to quickly remove the powder and debris generated by the friction between the brake pad and the brake disc, preventing the debris from adhering to the surface of the brake pad and brake disc and affecting the braking effect of the brake pad; however, the static electricity generated during braking causes the debris and powder to adhere to the grooves and the surface of the brake pad and cannot be removed quickly, which can easily damage the brake pad or brake disc and affect the braking effect.

[0003] The prior art patent document with publication number CN219549455U provides a brake pad structure. When the friction pad is worn to the avoidance groove position, the rotating part contacts the brake disc, and the rotating part is pushed to rotate by the rotating brake disc. When the groove moves into the outer shell, the gas in the groove enters the outer shell cavity, causing the air pressure in the outer shell cavity to change. The groove is either a rectangular groove or a circular groove. The circular motion of the groove in the outer shell can also drive the flow of gas in the outer shell cavity. Since the exhaust hole is connected to the external air pressure, the gas in the outer shell cavity flows from the exhaust hole and a whistle is emitted to remind the driver that the friction pad has been worn to a critical value and needs to be replaced. The structure is simple.

[0004] In the above-mentioned prior art, although grooves are provided on the existing brake pad abrasive to facilitate the removal of powder debris generated by friction, the static electricity generated during the braking process will cause the debris and powder to easily adhere to the grooves and the surface of the brake pad, making it difficult to effectively remove them. Under long-term use, these debris and powder are likely to damage the brake pad or brake disc, thereby affecting the braking effect and failing to meet people's needs. Therefore, a brake pad abrasive composite coating structure is needed. Utility Model Content

[0005] The purpose of the present utility model is to provide a brake pad abrasive composite coating structure to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a brake pad abrasive composite coating structure, comprising a mounting backplate, the outer wall of the mounting backplate is fixedly connected to the abrasive body, and the outer wall of the abrasive body is provided with a bevel, the inner wall of the abrasive body is provided with a heat dissipation and chip removal groove, the outer wall of the bevel and the inner wall of the heat dissipation and chip removal groove are both coated with a composite coating, the inner wall of the mounting backplate is provided with a mounting groove, and the inner wall of the mounting groove is fixedly connected to a heat conducting plate, the inner wall of the abrasive body is provided with a groove, the outer wall of the mounting backplate is fixedly connected to a backplate gasket, and the inner wall of the backplate gasket is provided with a heat dissipation hollow groove.

[0007] Preferably, the bevel shape is a J-shaped bevel.

[0008] Preferably, the heat dissipation and chip removal groove is in the shape of an oblique groove.

[0009] Preferably, there are multiple mounting slots, and the multiple mounting slots are equidistantly arranged on the mounting back plate.

[0012] Preferably, there are multiple heat dissipation hollow grooves, and the multiple heat dissipation hollow grooves are opened on the back plate gasket at equal distances.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0014] First, the present invention coats the beveled outer wall and the inner wall of the heat dissipation and chip removal groove with a composite coating, which can effectively eliminate the static electricity generated by the friction of the brake pad during the braking process. The elimination of static electricity prevents debris and powder from adhering to the groove and the surface of the brake pad due to electrostatic adsorption, thereby improving the efficiency of discharging debris and powder, avoiding the situation where debris and powder are difficult to clean due to static electricity, reducing the risk of debris and powder damaging the brake pad or brake disc, ensuring the stability and reliability of the braking effect, and meeting people's needs.

[0015] Second, the utility model provides multiple heat-conducting plates in the mounting groove of the mounting back plate. The heat-conducting plates can quickly conduct the heat generated during the braking process, thereby improving the heat dissipation efficiency, further ensuring the stable performance of the brake pads, and extending the service life of the brake pads.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-4 As shown, a brake pad abrasive composite coating structure includes a mounting back plate 1, the outer wall of the mounting back plate 1 is fixedly connected to the abrasive body 2, and the outer wall of the abrasive body 2 is provided with a grinding bevel 3, the inner wall of the abrasive body 2 is provided with a heat dissipation and chip removal groove 4, the outer wall of the grinding bevel 3 and the inner wall of the heat dissipation and chip removal groove 4 are coated with a composite coating 5, the inner wall of the mounting back plate 1 is provided with a mounting groove 6, and the inner wall of the mounting groove 6 is fixedly connected to a heat conducting plate 7, the inner wall of the abrasive body 2 is provided with a groove 8, the outer wall of the mounting back plate 1 is fixedly connected to a back plate gasket 9, and the inner wall of the back plate gasket 9 is provided with a heat dissipation hollow groove 10.

[0023] Through the above technical solution, a composite coating 5 is coated on the outer wall of the grind 3 and the inner wall of the heat dissipation and chip removal groove 4. The composite coating 5 can effectively eliminate the static electricity generated by the friction of the brake pad during the braking process. The elimination of static electricity makes the debris and powder no longer adhere to the groove and the surface of the brake pad due to electrostatic adsorption, thereby improving the discharge efficiency of the debris and powder, avoiding the situation where the debris and powder adhere to the groove due to static electricity and are difficult to clean, reducing the risk of debris and powder causing damage to the brake pad or brake disc, ensuring the stability and reliability of the braking effect, and meeting people's needs; by arranging multiple heat conducting plates 7 in the installation groove 6 of the installation back plate 1, the heat conducting plates 7 can quickly conduct the heat generated during the braking process, thereby improving the heat dissipation efficiency, further ensuring the stable performance of the brake pad, and extending the service life of the brake pad, and by providing multiple heat dissipation hollow grooves 10 on the back plate gasket 9, heat dissipation is facilitated, and the structure is simple and easy to use.

[0024] Specifically, the bevel 3 is in the shape of a J-shaped bevel.

[0025] Through the above technical solution, the J-shaped bevel grinding bevel 3 design can better guide the debris and dust generated by the friction of the brake pad to flow in a specific direction, thereby improving the chip removal efficiency; the composite coating 5 can also be applied to other brake pads. For example, the composite coating 5 can be applied to various grinding bevels 3 such as straight bevel, figure eight bevel, and composite bevel to facilitate chip removal.

[0026] Specifically, the heat dissipation and chip removal groove 4 is in the shape of an oblique groove.

[0027] Through the above technical solution, the heat dissipation and chip removal groove 4 in the shape of an oblique groove can utilize gravity and the airflow generated during braking to discharge the powder debris generated by friction more quickly, reduce the accumulation of debris on the brake pad, and help improve the heat dissipation performance of the brake pad; the composite coating 5 can also be applied to other brake pads. For example, the composite coating 5 can be applied to a variety of grooves such as single straight grooves, double straight grooves, double oblique grooves, V / U / S-shaped grooves, and horizontal grooves to facilitate chip removal.

[0028] Specifically, there are multiple mounting slots 6 , and the multiple mounting slots 6 are arranged on the mounting back plate 1 at equal distances.

[0029] The above technical solution facilitates installation of the heat conducting plate 7 in the plurality of installation grooves 6 .

[0030] Specifically, there are multiple heat conducting plates 7 , and the multiple heat conducting plates 7 are arranged in the mounting groove 6 at equal distances.

[0031] Through the above technical solution, multiple heat conducting plates 7 can more efficiently conduct the heat generated during the braking process, avoiding performance degradation or damage of the brake pads due to overheating, and the heat conducting plates 7 arranged at equal distances ensure uniform heat dissipation, thereby improving the heat dissipation effect of the brake pads.

[0032] Specifically, one end of the heat conducting plate 7 passes through the mounting back plate 1 and extends into the groove 8 , and the outer wall of the heat conducting plate 7 fits with the inner wall of the groove 8 .

[0033] Through the above technical solution, the close fit between the heat conducting plate 7 and the groove 8 ensures that heat can be quickly transferred from the brake pad to the heat conducting plate 7 and then dissipated through the heat conducting plate 7, thereby improving the heat dissipation efficiency and reducing the accumulation of heat inside the brake pad, thereby ensuring the stability of the braking performance.

[0034] Specifically, there are multiple heat dissipation hollow grooves 10 , and the multiple heat dissipation hollow grooves 10 are opened on the back plate gasket 9 at equal distances.

[0035] The above technical solution facilitates air to enter the installation groove 6 to dissipate heat from the heat conducting plate 7 .

[0036] During use, firstly, by providing a composite coating 5, static electricity generated by the friction of the brake pad can be eliminated, which is beneficial to the removal of debris and dust generated by the friction of the brake pad, and the removal efficiency of debris and powder is improved. The debris and dust can be discharged through the heat dissipation groove 4 and the grinding bevel 3, reducing the accumulation of debris on the brake pad; when friction generates heat, on the one hand, the heat dissipation groove 4 is opened to help dissipate heat, and on the other hand, the heat generated on the grinding material body 2 can be quickly transferred to multiple heat conduction plates 7, and the air enters the mounting groove 6 through the heat dissipation hollow groove 10 to dissipate heat for the heat conduction plate 7, ensuring uniform heat dissipation, improving heat dissipation efficiency, and avoiding performance degradation or damage of the brake pad due to overheating.
