Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to an automotive brake pad. Background Technology

[0002] Brake pads are friction materials fixed to the brake drum or brake disc that rotates with the wheel. They are typically made of materials such as metal, carbon fiber, or ceramic. Their core function is to convert the vehicle's kinetic energy into heat energy through direct friction with the brake disc, thereby achieving deceleration or stopping. To protect the surrounding automotive components, brake pads are equipped with a heat insulation layer. However, existing brake pads have poor heat insulation, causing them to soften due to excessive temperature, which affects their lifespan. Furthermore, the installation of some heat dissipation components can generate unnecessary noise, impacting the user experience.

[0003] In summary, existing technologies suffer from poor heat dissipation, and may generate noise while dissipating heat, thus affecting the lifespan of brake pads. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an automotive brake pad that can solve the problems of poor heat dissipation in existing technologies, which may generate noise while dissipating heat and affect the life of the brake pad. This utility model provides an automotive brake pad, which includes a friction layer, a heat insulation layer below the friction layer, and the heat insulation layer is connected to a steel plate by an adhesive. The steel plate has fixing plates on its left and right sides and openings on its front and rear sides. Sound-absorbing cotton is provided on the inner side of the openings. Heat dissipation fins are fixedly connected inside the steel plate. A sealing cover is provided at the bottom of the steel plate, and the sealing cover has five inner sides, each of which is provided with a sound-absorbing plate.

[0006] Optionally, the height of the two sides of the friction layer is lower than that of the middle, and multiple sound-absorbing holes are provided on the friction layer.

[0009] Optionally, the width and length of the heat dissipation fins are consistent with the sound-absorbing plate on the top of the sealing cover.

[0010] Optionally, the friction layer, heat insulation layer, adhesive, and steel plate are integrated as a single unit.

[0012] In summary, this utility model has at least one of the following beneficial effects:

[0013] This invention uses a heat insulation layer to initially isolate the temperature, and then increases the metal surface area by using heat dissipation fins to improve the heat dissipation effect. The heat dissipation fins may generate noise during operation, and the sound-absorbing plate and sound-absorbing sponge can effectively absorb the noise. The sound-absorbing holes can absorb the noise generated by friction, reducing the impact of noise and temperature on the life of the brake pads. Attached Figure Description

[0020] The following is in conjunction with the appendix Figure 1-4 This utility model will be described in further detail below.

[0021] Example 1, refer to Figure 1-4In this embodiment, to address the problem of poor heat dissipation in existing technologies, which may generate noise during heat dissipation and affect the lifespan of brake pads, this utility model discloses an automotive brake pad. It includes a friction layer 1 with sound-absorbing holes 2 for absorbing noise generated by friction. Below the friction layer 1 is a heat insulation layer 7, which insulates against the heat generated by friction in the friction layer 1 and the heat generated by sound absorption through the sound-absorbing holes 2. When the heat insulation layer 7 softens after prolonged use, heat will pass through the heat insulation layer 7 and the adhesive 6 to reach the steel plate 4. Since the steel plate 4 has internal heat dissipation fins 11, which increase the metal surface area to improve heat dissipation, the opening 5 increases the airflow between the inside and outside, ensuring effective heat dissipation. Because the heat dissipation fins 11 tend to generate noise during heat dissipation after prolonged use, the sound-absorbing plate 12 and sound-insulating sponge absorb the internal noise, ensuring the normal operation of the device. The sealing cover 9 is provided with fixing ears 8 around its perimeter. The fixing ears 8 are provided with fixing holes 13, which are compatible with the fixing grooves 10 on the bottom of the steel plate 4. They can be installed and removed with bolts, which facilitates subsequent cleaning and maintenance of the heat dissipation fins 11 and the sound-absorbing plate 12. Fixing plates 3 are provided on both sides of the steel plate 4. The fixing plates 3 have fixing holes 13, which facilitates the fixing of the brake pads.

[0022] Specific implementation principle: When using this utility model, the sound-absorbing holes 2 first absorb the noise generated by friction, preventing excessive noise. Part of the noise absorbed by the sound-absorbing holes 2 is converted into heat and insulated by the heat insulation layer 7. The other part passes through the heat insulation layer 7 and reaches the interior of the steel plate 4. The absorbed noise is then absorbed by the sound-absorbing plate 12 and the sound-insulating sponge. The heat generated by friction and the heat generated by the sound-absorbing holes 2 pass through the heat insulation layer 7, reducing the heat entering the steel plate 4. At this time, the heat insulation layer 7 plays a major role in cooling. When the heat insulation layer 7 softens after long-term use, the heat entering the interior of the steel plate 4... The cooling fins 11 will be used for heat dissipation, and the opening 5 can be used for ventilation. At the same time, the opening 5 is surrounded by 0.5-1cm thick sound insulation sponge, which can effectively reduce the impact of internal noise on the outside. The existing brake pads only have a heat insulation layer 7. After long-term use, the effect of the heat insulation layer 7 will decrease. The cooling fins 11 set in this application can not only ensure the heat dissipation effect, but also dissipate heat when the heat insulation layer 7 is ineffective, thus enhancing the service life of the brake pads. In addition, since the sealing cover 9 and the steel plate 4 are bolted together, subsequent cleaning and maintenance are also more convenient.

[0023] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
