[0002] In automotive braking systems, brake pads are key components for achieving braking function. Wear-resistant composite ceramic brake pads are automotive braking components made with ceramic fibers and ceramic powder as the core materials, mixed with metal or organic binders. They feature high wear resistance and high temperature resistance. Compared to traditional semi-metallic and organic brake pads, ceramic materials have higher hardness, and their lifespan under normal use is 30% to 50% longer than traditional brake pads, reducing replacement frequency. However, existing technologies have the following shortcomings in use: Existing composite ceramic brake pads generally have poor heat dissipation capabilities, limited contact area with air, and insufficient heat dissipation channels, making it difficult to quickly dissipate the heat generated during braking, which is not conducive to the long-term stable use of brake pads.

[0003] Therefore, there is an urgent need for a wear-resistant composite ceramic brake pad to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a wear-resistant composite ceramic brake pad that can solve the problems of poor heat dissipation capacity, limited contact area with air, and insufficient heat dissipation channels in existing composite ceramic brake pads, which make it difficult to quickly dissipate the heat generated during braking and hinder the long-term stable use of the brake pad.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The application is as follows: A wear-resistant composite ceramic brake pad includes a ceramic brake pad body, wherein the ceramic brake pad body includes a friction pad body, a heat insulation layer, an adhesive layer, a backing plate, and a sound-absorbing plate; The friction pad body has a first arched groove, a second arched groove, and two parallelogram grooves on its peripheral surface. The friction pad body has two first support plates and two second support plates on its inner surface. The first support plates and the second support plates are arc-shaped in their top view cross-section. The friction pad body is arc-shaped overall.

[0006] As a preferred technical solution of this application, the first arched groove is located directly in front of the second arched groove, and the two parallelogram grooves are located on opposite sides of the first arched groove and the second arched groove.

[0007] As a preferred technical solution of this application, the two first support plates and the second support plate are arranged in a rectangular shape around the friction plate body, and the first support plate and the second support plate are integrally formed with the friction plate body.

[0008] As a preferred technical solution of this application, a warning groove is provided through the middle of the upper surface of the friction pad body, and the warning groove is located between two parallelogram grooves.

[0009] As a preferred technical solution of this application, the adhesive layer is fixedly installed on the upper surface of the back plate, the friction pad body is located directly above the adhesive layer, and the heat insulation layer is fixedly installed between the friction pad body and the adhesive layer.

[0010] As a preferred technical solution of this application, the noise-absorbing plate is fixedly installed on the back of the friction plate body, the thickness of the friction plate body is 12mm to 14mm, and the thickness of the noise-absorbing plate is 2mm.

[0011] As a preferred technical solution of this application, the upper surface of the friction pad body is treated with wear resistance, and the thickness of the heat insulation layer is greater than the thickness of the adhesive layer.

[0012] As a preferred technical solution of this application, the two first support plates and the two second support plates are symmetrically distributed about the central axis of the friction plate body.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By opening the first arched groove, the second arched groove, and the two parallelogram grooves, the contact area between the friction pad body and the air is increased, which is conducive to the rapid dissipation of heat generated during braking, prevents the performance of the friction pad body from deteriorating due to high temperature, and helps to improve its thermal stability.

[0014] 2. The two first support plates and the two second support plates are all integrally formed with the friction plate body, which can ensure the structural strength of the friction plate body itself and enable it to maintain its shape stability under high-load braking.

[0015] 3. A warning groove is cut through the middle of the upper surface of the friction pad body. When the friction pad body is about to wear down to the bottom wall of the warning groove, it can intuitively remind the user that the ceramic brake pad body needs to be replaced in time to avoid brake failure due to excessive wear of the friction pad body.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0023] In the description of this utility model, it should be noted that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, or the orientation or positional relationship commonly understood by those skilled in the art. These terms are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used to distinguish the description and should not be construed as indicating or implying relative importance.

[0024] Example: like Figure 1-5As shown, this embodiment proposes a wear-resistant composite ceramic brake pad, including a ceramic brake pad body 1. The ceramic brake pad body 1 includes a friction pad body 2, a heat insulation layer 3, an adhesive layer 4, a backing plate 5, and a sound-absorbing plate 6. The friction pad body 2 is made of composite ceramic material and has high wear resistance. The peripheral surface of the friction pad body 2 is provided with a first arched groove 7, a second arched groove 8, and two parallelogram grooves 9. The first arched groove 7 is located directly in front of the second arched groove 8, and the two parallelogram grooves 9 are located on opposite sides of the first arched groove 7 and the second arched groove 8. The inner surface of the friction pad body 2 is provided with two... The first support plate 10 and the two second support plates 11 are both arc-shaped in their top cross-section. The two first support plates 10 and the two second support plates 11 are symmetrically distributed about the central axis of the friction pad body 2. The friction pad body 2 is arc-shaped as a whole. The first arched groove 7, the second arched groove 8 and the two parallelogram grooves 9 increase the contact area between the friction pad body 2 and the air to a certain extent. This is conducive to the rapid dissipation of heat generated during braking, prevents the performance of the friction pad body 2 from deteriorating due to high temperature, and helps to improve its thermal stability.

[0025] like Figure 1 and Figure 2 As shown, the two first support plates 10 and the second support plate 11 are arranged in a rectangular shape around the friction plate body 2, and the first support plate 10 and the second support plate 11 are integrally formed with the friction plate body 2. The two first support plates 10 and the two second support plates 11, which are integrally formed, can ensure the structural strength of the friction plate body 2 itself, so that it can maintain its shape stability under high-load braking.

[0026] like Figure 1 and Figure 2 As shown, a warning groove 12 is provided through the middle of the upper surface of the friction pad body 2. The warning groove 12 is located between two parallelogram grooves 9. When the friction pad body 2 is worn down to the bottom wall of the warning groove 12, it can intuitively remind the user that the ceramic brake pad body 1 needs to be replaced in time to avoid brake failure due to excessive wear of the friction pad body 2.

[0027] like Figure 3 As shown, the adhesive layer 4 is fixedly installed on the upper surface of the back plate 5, the friction pad body 2 is located directly above the adhesive layer 4, and the heat insulation layer 3 is fixedly installed between the friction pad body 2 and the adhesive layer 4. The adhesive layer 4 can be a modified phenolic resin adhesive. Through the adhesive layer 4, the friction pad body 2, the heat insulation layer 3 and the back plate 5 can be firmly bonded, enhancing the reliability of the overall structure. The thickness of the heat insulation layer 3 is greater than the thickness of the adhesive layer 4. The heat insulation layer 3 can be made of ceramic fiber composite material, which can effectively block the transfer of braking heat to the back plate 5, helping to ensure thermal stability.

[0028] like Figure 5As shown, the noise-absorbing plate 6 is fixedly installed on the back of the friction plate body 2. The thickness of the friction plate body 2 is 12mm to 14mm, and the thickness of the noise-absorbing plate 6 is 2mm. The noise-absorbing plate 6 can be made of nitrile rubber composite damping material, which can effectively absorb vibration during braking and reduce noise.

[0029] like Figure 1 As shown, the upper surface of the friction pad body 2 is treated with wear resistance and is coated with a ceramic-based composite coating, which helps to enhance the wear resistance of the friction pad body 2.

[0030] The working principle of the above embodiment is as follows: By opening the first arched groove 7, the second arched groove 8, and the two parallelogram grooves 9, the contact area between the friction pad body 2 and the air is increased to a certain extent, which is conducive to the rapid dissipation of heat generated during braking, preventing the performance degradation of the friction pad body 2 due to high temperature, and helping to improve its thermal stability. The two first support plates 10 and two second support plates 11, which are integrally formed, can ensure the structural strength of the friction pad body 2 itself, so that it can still maintain its shape stability under high-load braking. At the same time, under the premise of ensuring structural strength, the material usage of the friction pad body 2 is reduced by opening the first arched groove 7, the second arched groove 8, and the two parallelogram grooves 9, which reduces the overall weight of the ceramic brake pad body 1 and helps to improve the braking response speed and fuel economy of the car. The sound-absorbing plate 6 set on the back of the back plate 5 can absorb the vibration between the friction pad body 2 and the brake disc during braking, which helps to reduce braking noise.

[0031] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
