Description

Technical Field

[0001] This utility model belongs to the field of braking equipment, and specifically relates to a brake and a noise reduction structure. Background Technology

[0002] A brake is a mechanical device that slows down, stops, or keeps a moving part (or machine) at a stop. Currently, some brakes may exhibit noise problems during operation. During braking, the brake pads rub intensely, generating high-frequency vibrations and thus noise. A conventional method to address this is to add lubricant to the surface of the brake pads, reducing the coefficient of friction and lowering the vibration amplitude, thereby reducing noise. However, adding lubricant can affect braking performance, and the lubricating performance of the lubricant decreases at high temperatures, potentially even carbonizing and failing, resulting in poor noise control. Furthermore, with frequent use, the lubricant gradually depletes, requiring regular replenishment or replacement, which not only increases maintenance costs but may also affect noise reduction effectiveness if maintenance is not timely. In addition, some brakes use thicker brake pads or discs, hoping to suppress vibration by increasing structural mass. However, this increases the overall mass of the brake, increasing energy consumption and potentially affecting the equipment's handling performance. Moreover, the thickened structure limits the application scenarios of the brake, making it difficult to adapt to space-constrained equipment. Therefore, a new structure is needed to solve the aforementioned technical problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a brake and noise reduction structure to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a brake and a noise reduction structure, comprising: a braking assembly and a noise reduction assembly, wherein a noise reduction component for noise reduction is installed on the outer surface of the braking assembly, the braking assembly includes a first brake pad and a second brake pad for generating braking function, a partition is installed between the first brake pad and the second brake pad, and the noise reduction assembly includes a noise reduction cover for reducing the noise generated by braking, the braking assembly is installed inside the noise reduction cover, and a sound insulation layer and a sound-absorbing block are installed inside the noise reduction cover to improve the noise reduction effect of the noise reduction assembly.

[0005] In a preferred embodiment, the diameter of brake pad one matches the diameter of brake pad two, a drum is integrally formed at the center of brake pad one, brake grooves are formed on the outer surfaces of brake pad one and brake pad two, and a gap is provided between brake pad one and brake pad two.

[0006] In a preferred embodiment, a partition is installed in the gap between brake pad one and brake pad two. The partition is arranged in a ring structure, and a sound insulation cavity is formed between every two partitions. The sound insulation cavity is filled with sound insulation cotton.

[0007] In a preferred embodiment, the diameter of the noise reduction cover is larger than the diameter of the braking assembly, the outer surface of the noise reduction cover is provided with a brake caliper opening, and brake pad one and brake pad two are installed inside the noise reduction cover.

[0008] In a preferred embodiment, a sound-insulating layer is installed on the inner surface of the noise-reducing cover. The sound-insulating layer is made of sound-absorbing rubber, and its thickness is less than that of the noise-reducing cover.

[0009] In a preferred embodiment, a plurality of sound-absorbing blocks are uniformly installed on the inner surface of the sound insulation layer. The sound-absorbing blocks are conical in shape and made of rubber. The side of the sound-absorbing block away from the noise reduction cover does not contact the outer surface of the braking assembly.

[0010] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting a braking assembly, the braking assembly includes a brake pad 1 and a brake pad 2 for generating braking function. A partition is installed between brake pad 1 and brake pad 2, and a sound insulation cavity is formed between each two partitions. The sound insulation cavity is filled with sound insulation cotton. When in use, the combination of the sound insulation cavity and the sound insulation cotton can effectively block the noise generated by brake pad 1 and brake pad 2 during braking. When braking, the friction between the brake pads will produce a harsh sound. The sound insulation cavity can initially reduce the propagation of sound through the buffering and reflection of air, while the sound insulation cotton, with its porous structure, further absorbs and dissipates sound wave energy, thus greatly reducing the noise propagating outward.

[0011] 2. By setting up a noise reduction component, a noise reduction component is installed on the outer surface of the braking component. The noise reduction component includes a noise reduction cover for reducing the noise generated by braking. The braking component is installed inside the noise reduction cover. The noise reduction cover also contains a sound insulation layer and sound-absorbing blocks to improve the noise reduction effect of the noise reduction component. When in use, the noise reduction cover, as the outermost noise reduction structure, can directly block the sound generated by the braking component from propagating outward, forming a barrier that confines most of the noise to its internal space and reduces the diffusion of noise to the surrounding environment.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Please see Figures 1 to 4 This utility model provides a technical solution: a brake and a noise reduction structure, including: a brake assembly and a noise reduction assembly 200. The outer surface of the brake assembly is equipped with the noise reduction assembly 200 for noise reduction. The brake assembly includes a brake pad 100 and a brake pad 110 for generating braking function. A partition 120 is installed between the brake pad 100 and the brake pad 110. The noise reduction assembly 200 includes a noise reduction cover 210 for reducing the noise generated by braking. The brake assembly is installed inside the noise reduction cover 210. A sound insulation layer 220 and a sound-absorbing block 230 are installed inside the noise reduction cover 210 to improve the noise reduction effect of the noise reduction assembly 200.

[0020] Please see Figures 1 to 4As the first embodiment of this utility model: the diameter of brake pad 100 matches the diameter of brake pad 210, a drum 101 is integrally formed at the center of brake pad 100, brake grooves are provided on the outer surfaces of brake pad 100 and brake pad 210, and a gap is provided between brake pad 100 and brake pad 210.

[0021] A partition 120 is installed in the gap between brake pad 100 and brake pad 110. The partition 120 is arranged in a ring structure. A sound insulation cavity 121 is formed between every two partitions 120. The sound insulation cavity 121 is filled with sound insulation cotton.

[0022] When the braking components are installed inside the device, they generate noise due to friction with the brake calipers. This noise is also generated when brake pads 100 and 110 rub against each other. Because brake pads 100 and 110 form a hollow structure through their internal partitions 120, and the sound insulation cavities 121 and sound insulation cotton between each pair of sound insulation materials initially reduce the noise generated by brake pads 100 and 110. Finally, external noise reduction components on their outer surfaces further reduce the noise. 200 performs secondary noise reduction, thereby greatly reducing the generation of noise (it cannot completely eliminate noise, but only has the effect of noise reduction). Since the combination of sound insulation cavity 121 and sound insulation cotton can effectively block the noise generated by brake pad 100 and brake pad 110 during braking, the friction between brake pads will produce a harsh sound during braking. Sound insulation cavity 121 can initially reduce the propagation of sound through the buffering and reflection of air, while sound insulation cotton uses its porous structure to further absorb and dissipate sound wave energy, thus greatly reducing the noise propagating outward.

[0023] Please see Figures 1 to 4 As a second embodiment of the present invention: the diameter of the noise reduction cover 210 is larger than the diameter of the braking assembly, the outer surface of the noise reduction cover 210 is provided with a brake caliper mouth 240, and the interior of the noise reduction cover 210 is equipped with a brake pad 100 and a brake pad 110.

[0024] The inner surface of the noise reduction cover 210 is equipped with a sound insulation layer 220. The sound insulation layer 220 is made of sound-absorbing rubber and its thickness is less than that of the noise reduction cover 210.

[0025] Multiple sound-absorbing blocks 230 are evenly installed on the inner surface of the sound insulation layer 220. The sound-absorbing blocks 230 have a conical structure and are made of rubber. The side of the sound-absorbing block 230 away from the noise reduction cover 210 does not contact the outer surface of the braking component.

[0026] When the braking assembly is used to reduce noise through the operation steps of the first embodiment, the noise reduction cover 210 installed on the outer surface of the braking assembly can play a secondary noise reduction role. When the braking assembly generates noise, the noise reduction cover 210, together with its internal sound insulation layer 220 and sound absorption block 230, can absorb the generated noise, thereby achieving a secondary noise reduction effect. Since the noise reduction cover 210 is the outermost noise reduction structure, it can directly block the sound generated by the braking assembly from spreading outward, forming a barrier, confining most of the noise in its internal space, and reducing the diffusion of noise to the surrounding environment.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
