Description

Technical Field

[0001] The utility model relates to the technical field of automobile brake parts, in particular to a shock-absorbing plate of a disc brake pad. Background Art

[0002] Automobile brake parts refer to the various components that make up the automobile braking system. They work together to enable a moving car to slow down, stop or maintain a stable speed.

[0003] With the development of the automobile industry, disc brake systems have been widely used due to their efficient braking performance. During the disc braking process, the friction between the brake pads and the brake discs will generate vibration and noise, which not only affects the driving comfort, but may also cause damage to other components of the braking system. Existing shock-absorbing pads have certain limitations in alleviating these problems. It is necessary to develop a shock-absorbing pad for disc brake pads that is easy to use.

[0004] Chinese patent announcement number: CN214617611U discloses "A high-temperature resistant disc brake pad". The high-temperature resistant disc brake pad includes a metal layer, the outer surface of the metal layer is fixedly connected with a high-temperature adhesive, the metal layer is fixedly connected with a fiber layer through the high-temperature adhesive, the outer surface of the fiber layer is fixedly connected with a silencer through the high-temperature adhesive, the outer surface of the silencer is fixedly connected with a phenolic layer through the high-temperature adhesive, and the heat insulation performance of the phenolic layer is utilized to isolate the heat generated during operation of the brake pad to prevent the generated heat from being transferred to the metal layer in large quantities, thereby increasing the heat dissipation speed of the device and avoiding excessive surface temperature of the brake pad, which may cause deformation of the brake pad. A plurality of heat dissipation holes are provided inside the phenolic layer, the outer surface of the phenolic layer is fixedly connected with a bottom pad through a high-temperature adhesive, the outer surface of the bottom pad is bonded with a friction layer through a high-temperature adhesive, and the outer surface of the metal layer is fixedly connected with an inorganic silicone paint layer.

[0005] The above-mentioned existing technology utilizes the heat insulation performance of the phenolic layer to isolate the heat generated by the brake pad when it is working, preventing the generated heat from being transferred to the metal layer in large quantities, thereby improving the heat dissipation speed of the device and avoiding excessively high surface temperature of the brake pad, which may cause deformation of the brake pad. However, the existing equipment does not have the function of processing the heat and noise generated by the brake pad when it is working during use. The intense friction between the brake pad and the brake disc will cause the temperature of the brake pad to rise sharply in a short period of time, which will not only affect the performance of the brake pad itself, but also reduce its service life to a certain extent, and the noise will affect the comfort of the passengers in the car.

[0024] Through the above technical solution, the crescent-shaped through groove 9 and the rectangular through groove 10 are set to achieve the functions of heat dissipation and noise reduction. A crescent-shaped through groove 9 is set on the entrance side of the shock-absorbing and silencer plate 8 along the rotation direction of the brake disc, and a rectangular through groove 10 is opened just below the middle process hole to achieve the purpose of heat dissipation and noise reduction, thereby improving the service life of the brake pad to a certain extent, ensuring the performance of the brake pad and improving the comfort. By setting the left-pointing arrow 11 and the right-pointing arrow 13, the directions of the left brake pad 1 and the right brake pad 12 can be quickly distinguished to reduce incorrect assembly. At the same time, a protrusion 4, a horizontal bar 5 and a vertical bar 6 are set on one side of the left brake pad 1 and the right brake pad 12 to increase the friction of the left brake pad 1 and strengthen the brake pad to extend the service life of the brake pad.

[0025] Specifically, the crescent-shaped through groove 9 is provided on the inlet side of the shock-absorbing and noise-reducing plate 8 along the rotation direction of the brake disc.

[0026] Through the above technical solution, the crescent-shaped through groove 9 is precisely arranged on the inlet side of the shock-absorbing and sound-absorbing plate 8 along the rotation direction of the brake disc. During the braking process, air can pass smoothly, thereby effectively reducing the noise caused by air disturbance and having a positive impact on the heat dissipation and pressure balance of the braking system.

[0027] Specifically, the rectangular through groove 10 is arranged below the middle process hole of the shock-absorbing and sound-absorbing plate 8 .

[0028] Through the above technical solution, the rectangular through groove 10 is accurately set below the middle process hole of the shock-absorbing and sound-absorbing plate 8, which helps to optimize the vibration characteristics of the shock-absorbing and sound-absorbing plate 8 during braking and further enhance its ability to absorb and suppress noise.

During the braking process, it can better disperse pressure, enhance heat dissipation, suppress vibration and reduce noise, providing strong guarantee for the efficient and stable operation of the entire braking system.

[0037] During use, when it is necessary to ensure the heat dissipation and noise reduction effects of the left brake pad 1, a crescent-shaped through groove 9 is provided on the inlet side of the shock-absorbing and silencer plate 8 along the rotation direction of the brake disc, and a rectangular through groove 10 is opened just below the middle process hole, so as to achieve the purpose of heat dissipation and noise reduction at the same time. When it is necessary to facilitate assembly, a left-pointing arrow 11 and a right-pointing arrow 13 are respectively provided in the relative directions of the crescent-shaped through groove 9, so as to quickly distinguish the left and right directions of the left brake pad 1 and the right brake pad 12, thereby reducing incorrect assembly. When it is necessary to increase the service life of the left brake pad 1, a protrusion 4, a horizontal bar 5 and a vertical bar 6 are provided on one side of the left brake pad 1 to increase the braking friction of the left brake pad 1, and at the same time reinforce the left brake pad 1 to extend the service life of the left brake pad 1.
