Description

Technical Field

[0001] This utility model relates to the field of disc brake technology, specifically to a shock-absorbing and noise-reducing disc brake. Background Technology

[0002] Disc brakes are a type of braking system primarily used in vehicles. Structurally, they mainly consist of brake discs and brake calipers. The brake disc is a metal disk, typically mounted on the wheel axle. The brake caliper, including brake pads and pistons, is mounted on the vehicle frame or axle. When braking, pressure is applied via the brake lever or brake pedal, causing the pistons within the caliper to push the brake pads tightly against the disc. Friction then reduces the wheel's rotational speed, ultimately achieving braking. Compared to traditional braking systems, disc brakes offer numerous advantages, including stronger braking force, more sensitive response, and adaptability to harsh environments.

[0003] Currently, disc brake systems face several pressing issues in practical use. Disc brakes are prone to generating annoying noise during operation, especially with frequent braking causing overheating of the brake pads, resulting in a particularly noticeable harsh sound. The root cause is the lack of an effective heat dissipation mechanism during braking. The large amount of heat generated during braking cannot dissipate quickly, accumulating on the brake pads and surrounding components. This not only severely disrupts the quiet driving environment but also significantly shortens the normal lifespan of the brake pads. Over time, this can lead to a substantial reduction in braking performance, posing a safety hazard. Furthermore, the rough surface of worn brake pads can cause significant vibration during braking. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a shock-absorbing and noise-reducing disc brake that incorporates multiple brake pads to enhance braking performance and features a heat dissipation structure to effectively prevent overheating and wear vibration of the brake pads.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a shock-absorbing and noise-reducing disc brake, comprising:

[0006] A supporting frame, wherein the supporting frame is inverted U-shaped;

[0007] The side brake pads include a left brake pad and a right brake pad located opposite each other on the lower inner side of the support frame. The left brake pad and the right brake pad are driven by hydraulic cylinder 1 and hydraulic cylinder 2, which are fixed on the support frame, respectively. There are two left brake pads and one right brake pad, which can be opposite to the two left brake pads at the same time. Several heat dissipation grooves 1 and 2 are respectively provided on the opposite side of the left brake pad and the right brake pad.

[0008] The top brake pad is located inside the support frame and above the left and right brake pads. The top brake pad is driven by a hydraulic cylinder fixed on the support frame. The lower wall of the top brake pad is provided with a heat dissipation groove.

[0009] Furthermore, the first heat dissipation groove on the left brake pad is an interlaced X-shaped oblique groove, and the second heat dissipation groove on the right brake pad is a horizontal groove.

[0010] Furthermore, the left brake pad and the right brake pad are provided with several anti-slip protrusions on opposite sides, and the heat dissipation groove on the right brake pad is provided with several perforated grooves.

[0011] Furthermore, the top brake pad is an arc-shaped plate that curves downwards on both sides.

[0012] Furthermore, the heat dissipation grooves on the top brake pad are horizontal grooves.

[0013] Furthermore, the lower wall of the side brake pad opposite to the top brake pad is made of ceramic fiber material.

[0014] Compared with existing technologies, the advantages of this invention are as follows: The use of multiple brake pads enhances the braking effect. Two brake pads are provided on the left, and one brake pad is provided on the right, opposite to the left. The top brake pad is located between and above the other two. This arrangement increases the contact area with the wheel hub during braking, improving braking friction and enabling more efficient vehicle deceleration and stopping, significantly enhancing braking reliability and stability. Furthermore, the presence of two brake pads on the left avoids the possibility of brake failure due to the damage of a single brake pad, ensuring safety and practicality.

[0015] The left, right, and top brake pads are respectively equipped with heat dissipation grooves one, two, and three, with a reasonable groove design. For example, the X-shaped diagonal grooves on the left brake pad and the horizontal grooves on the right brake pad work together to increase the heat dissipation area and enhance air turbulence. The horizontal grooves on the top brake pad facilitate rapid heat dissipation, and the perforated grooves on the right brake pad further aid in heat dissipation. The opposite sides of the side brake pads and the lower wall of the top brake pad are made of ceramic fiber material. Its excellent high-temperature resistance and wear resistance not only extend the service life of the brake pads but also prevent vibration caused by local overheating or uneven wear. This achieves vibration reduction and noise reduction, reducing the noise generated during braking and the adverse effects of wear vibration on the braking system and the overall performance of the vehicle, thus improving the overall performance and quality of the disc brakes.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Combined with appendix Figure 1 Appendix Figure 3 A shock-absorbing and noise-reducing disc brake includes: a support frame 1, wherein the support frame 1 is inverted U-shaped;

[0025] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 5 Appendix Figure 6 The side brake pads include a left brake pad 2 and a right brake pad 3 located opposite each other on the lower inner side of the support frame 1. The left brake pad 2 and the right brake pad 3 are driven by a hydraulic cylinder 4 and a hydraulic cylinder 5 fixed on the support frame 1, respectively. There are two left brake pads 2 and one right brake pad 3 that can be opposite to both left brake pads 2 at the same time. The left brake pad 2 and the right brake pad 3 are respectively provided with a plurality of heat dissipation grooves 1 and 2 on their opposite sides. The heat dissipation grooves 1 on the left brake pad 2 are intersecting X-shaped oblique grooves, and the heat dissipation grooves 2 on the right brake pad 3 are horizontal grooves. This can increase the heat dissipation area and air disturbance, improve heat dissipation efficiency, reduce noise and avoid wear. At the same time, it can also prevent the heat dissipation grooves 1 and 2 from being aligned in the same direction and causing the two sides of the wheel hub to be guided in the same direction, ensuring a good friction braking effect. The left brake pad 2 and the right brake pad 3 are provided with several anti-slip protrusions on opposite sides. The heat dissipation groove on the right brake pad 3 is provided with several perforated grooves. The anti-slip protrusions and perforated grooves can enhance braking friction, and the perforated grooves can also help to further dissipate heat.

[0026] Combined with appendix Figure 1 Appendix Figure 3 Appendix Figure 4The top brake pad 6 is located inside the support frame 1 and above the left brake pad 2 and right brake pad 3. The top brake pad 6 is an arc-shaped plate that curves downwards on both sides, allowing for better fit to the wheel hub and improving braking performance and stability. The top brake pad 6 is driven by a hydraulic cylinder 7 fixed to the support frame 1. The lower wall of the top brake pad 6 has heat dissipation grooves. These grooves are horizontal, facilitating rapid heat dissipation and effectively reducing the brake pad temperature, thereby reducing noise and preventing wear.

[0027] Combined with appendix Figure 4 The lower wall of the side brake pad opposite to the top brake pad 6 is made of ceramic fiber, which has good high temperature resistance and wear resistance, can extend the service life of the brake pad and improve braking reliability, and avoid vibration during braking caused by local wear of the brake pad.

[0028] The specific implementation of this utility model is as follows: During installation, the support frame 1 is installed above the motorcycle wheel hub, and the left brake pad 2 and the right brake pad 3 are respectively located on both sides of the wheel hub, the top brake pad 6 is located above the wheel hub, and the hydraulic cylinder 1 4, hydraulic cylinder 2 5, and hydraulic cylinder 3 7 are connected to the motorcycle braking system.

[0029] When the shock-absorbing and noise-reducing disc brake is needed for braking, the motorcycle braking system activates hydraulic cylinders 4, 5, and 7. Hydraulic cylinders 4 and 5, fixed to the support frame 1, begin to operate. Hydraulic cylinder 4 pushes the two left brake pads 2 towards the wheel hub, while hydraulic cylinder 5 pushes the right brake pad 3 towards its corresponding position. The left and right brake pads 2 and 3 gradually contact the wheel hub, generating friction. The anti-slip protrusions further enhance the braking friction, causing the vehicle to begin to decelerate. Simultaneously, the X-shaped diagonal grooves on the left brake pad 2 and the perforated horizontal grooves on the right brake pad 3 begin to function, increasing the heat dissipation area and turbulent the airflow to quickly dissipate the heat generated during braking.

[0030] The top brake pad 6, located inside the support frame 1 and above the left brake pad 2 and right brake pad 3, also moves closer to and fits against the wheel hub under the drive of the hydraulic cylinder 7. The top brake pad 6 is an arc-shaped plate curved downwards on both sides, allowing it to fit tightly against the wheel hub. The horizontal grooves on its lower wall help dissipate heat, effectively reducing the brake pad temperature. Throughout the braking process, the ceramic fiber material on the opposite side of the side brake pads and the lower wall of the top brake pad 6, with its excellent high-temperature resistance and wear resistance, ensures stable operation of the brake pads, reduces wear vibration, and achieves shock absorption and noise reduction, enabling the vehicle to decelerate and brake smoothly and safely.
