Description

Technical Field

[0001] This utility model relates to the field of brake pad technology, specifically to a low-noise, wear-resistant brake pad for a disc brake assembly. Background Technology

[0002] Brake pads, also known as brake discs, are the most critical safety component in the braking systems of various motorcycles, electric motorcycles, electric two-wheelers, and electric tricycles. The effectiveness of braking depends entirely on the brake pads. Brake pads generally consist of a steel plate, an adhesive heat-insulating layer, and friction blocks. The heat-insulating layer is made of a non-heat-conducting material for heat insulation. The friction blocks are composed of friction materials and adhesives, and during braking, they are pressed against the brake disc and brake drum to generate friction, thereby achieving the purpose of decelerating and braking the vehicle.

[0003] Existing brake pads typically have few surface grooves, which results in significant noise during braking. Additionally, the brake pad materials are often limited and not wear-resistant. To address this, we propose a low-noise, wear-resistant brake pad for disc brake assemblies. Utility Model Content

[0004] The purpose of this invention is to provide a low-noise, wear-resistant brake pad for a disc brake assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A low-noise, wear-resistant brake pad for a disc brake assembly includes a brake pad body. The top of the brake pad body has a first groove, a second groove, a third groove, and a fourth groove. The bottom of the brake pad body has several threaded grooves. A steel plate layer is fixedly disposed inside the brake pad body, forming the bottom layer. An adhesive heat-insulating layer is fixedly disposed on top of the steel plate layer. A carbon fiber layer is fixedly disposed on top of the adhesive heat-insulating layer. A ceramic fiber layer is fixedly disposed on top of the carbon fiber layer. A NAO (non-aerated oxygen) formulation layer is fixedly disposed on top of the ceramic fiber layer, forming the outermost layer of the brake pad body.

[0007] Preferably, a brake base plate is provided at the bottom of the brake pad body, and a mounting groove is provided at the top of the brake base plate.

[0008] The above solution allows the brake pad body to be installed on top of the brake base plate by setting an installation slot.

[0009] Preferably, the top of the mounting groove is provided with a threaded hole, and the fixing bolt is threadedly connected to the threaded hole.

[0010] The above scheme, by setting threaded holes, allows the fixing bolts to be threadedly connected to the threaded holes and threaded grooves, thereby fixing the brake pad body and the brake base plate together.

[0011] Preferably, the brake pad body is fixedly connected to the brake base plate by fixing bolts, and the brake base plate has first fixing screw holes at both ends.

[0012] With the above solution, by setting the first fixing screw hole, the brake base plate is fixed to the brake assembly by connecting the first fixing screw hole with a bolt thread.

[0013] Preferably, the brake base plate has second fixing screw holes at both ends.

[0014] With the above solution, by setting a second fixing screw hole, the brake base plate is fixed to the brake assembly by connecting the second fixing screw hole with a bolt thread.

[0015] Preferably, the brake base plate has third fixing screw holes at both ends.

[0016] With the above solution, by setting a third fixing screw hole, the brake base plate is fixed to the brake assembly by connecting the third fixing screw hole with a bolt thread.

[0017] Preferably, the brake base plate is fixedly connected to the brake assembly using bolts through the first fixing screw hole, the second fixing screw hole, and the third fixing screw hole.

[0018] The above scheme uses the movement of the brake base plate to move the brake pad body.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. The low-noise wear-resistant brake pad of the disc brake assembly, through the first groove, second groove, third groove and fourth groove opened on the surface of the brake pad body, can reduce the noise and improve the heat dissipation when the brake pad body brakes the brake disc.

[0021] 2. The low-noise and wear-resistant brake pad of this disc brake assembly improves the wear resistance of the device by layering carbon fiber, ceramic fiber and NAO formula layers. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 - Figure 4 As shown, this utility model provides a technical solution:

[0029] A low-noise, wear-resistant brake pad for a disc brake assembly includes a brake pad body 1. The top of the brake pad body 1 has a first groove 2, a second groove 3, a third groove 4, and a fourth groove 5. The bottom of the brake pad body 1 has several threaded grooves 6. A steel plate layer 7 is fixedly disposed inside the brake pad body 1, forming the bottom layer of the brake pad body 1. An adhesive heat insulation layer 8 is fixedly disposed on top of the steel plate layer 7. A carbon fiber layer 9 is fixedly disposed on top of the adhesive heat insulation layer 8. A ceramic fiber layer 10 is fixedly disposed on top of the carbon fiber layer 9. A NAO formula layer 11 is fixedly disposed on top of the ceramic fiber layer 10, forming the outermost layer of the brake pad body 1.

[0030] NAO formulation layer 11 is a brake pad formulation using materials such as plant fibers, aramid fibers, glass fibers, ceramic fibers, and carbon fibers. The main advantages of this formulation are good resistance to heat fade, a high coefficient of friction, and environmental friendliness. Ceramic fiber layer 10 is primarily composed of ceramic fibers, exhibiting good thermal stability and wear resistance. Carbon fiber layer 9 uses carbon fiber reinforcement materials, possessing high modulus, good thermal conductivity, and heat resistance, making it suitable for high-performance vehicles. The combined use of these three materials improves the wear resistance of the device.

[0031] In this embodiment, preferably, a brake base plate 12 is provided at the bottom of the brake pad body 1, and a mounting groove 13 is provided at the top of the brake base plate 12. A threaded hole 14 is provided at the top of the mounting groove 13. A fixing bolt 15 is threadedly connected to the threaded hole 14. The brake pad body 1 is fixedly connected to the brake base plate 12 by the fixing bolt 15. A first fixing screw hole 16 is provided at both ends of the brake base plate 12, a second fixing screw hole 17 is provided at both ends of the brake base plate 12, and a third fixing screw hole 18 is provided at both ends of the brake base plate 12. The brake base plate 12 is fixedly connected to the brake assembly by bolts through the first fixing screw hole 16, the second fixing screw hole 17, and the third fixing screw hole 18.

[0032] With the above scheme, the mounting groove 13 allows the brake pad body 1 to be mounted on the top of the brake base plate 12. The threaded hole 14 allows the fixing bolt 15 to be threadedly connected to the threaded hole 14 and the threaded groove 6, thus fixing the brake pad body 1 to the brake base plate 12. The first fixing screw hole 16 allows the brake base plate 12 to be fixed to the brake assembly by bolt thread connection to the first fixing screw hole 16. The second fixing screw hole 17 allows the brake base plate 12 to be fixed to the brake assembly by bolt thread connection to the second fixing screw hole 17. The third fixing screw hole 18 allows the brake base plate 12 to be fixed to the brake assembly by bolt thread connection to the third fixing screw hole 18. The movement of the brake base plate 12 drives the brake pad body 1 to move.

[0033] In this embodiment, a low-noise wear-resistant brake pad for a disc brake assembly, through the first groove 2, second groove 3, third groove 4 and fourth groove 5 opened on the surface of the brake pad body 1, can reduce the noise and improve heat dissipation when the brake pad body 1 brakes the brake disc. The carbon fiber layer 9, ceramic fiber layer 10 and NAO formula layer 11 are provided to improve the wear resistance of the device by multiple layers of material of the brake pad body 1.
