Description

Technical Field

[0001] This utility model relates to the field of brake band technology, and in particular to a fracture-resistant brake band. Background Technology

[0002] Brake bands are mechanical moving parts that use friction to stop the moving parts, achieving the purpose of rapid braking. There are many types of brake bands, suitable for different application scenarios.

[0003] As a core component of the braking system, the performance of brake bands directly affects the safety and reliability of vehicles. Traditional brake bands mostly use a single material or a simple laminated structure, which are prone to breakage and accelerated wear under high load, high temperature and frequent braking conditions, leaving room for optimization. Therefore, it is necessary to design a breakage-resistant brake band to solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide a fracture-resistant brake band to solve the problem of the simple structure mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fracture-resistant brake band, comprising a brake band body and a friction layer, wherein the friction layer is disposed inside the brake band body;

[0006] The friction layer has a reinforcing layer on its inner side, and a buffer layer on its inner side. The buffer layer has a base layer on its inner side. The buffer layer consists of an outer layer, a middle layer, and an inner layer. The outer layer is located outside the middle layer, and the middle layer is located outside the inner layer. The friction layer is filled with nanoparticles. The base layer consists of a plating layer and a backing plate.

[0007] Furthermore, the top of the back plate is provided with a groove, and the cross-section of the groove is configured as a honeycomb shape.

[0008] Furthermore, the coating is applied to the outer side of the back plate, the coating material is silane, and the back plate material is aluminum alloy.

[0009] Furthermore, the outer layer is made of porous aluminum foam, the middle layer is made of Kevlar fiber woven mesh, and the inner layer is made of silicone rubber.

[0010] Furthermore, the reinforcing layer is woven from a first reinforcing fiber and a second reinforcing fiber, both of which are made of carbon fiber.

[0011] Furthermore, the nanoparticles are made of graphene.

[0012] Compared with the prior art, the beneficial effect of this utility model is that the fracture-resistant brake band realizes the fracture-resistant function of the composite structure;

[0013] By designing the brake band body into a four-layer composite structure, each layer complements the others and synergistically enhances overall performance. First, the friction layer is made of ceramic fiber, high-carbon steel fiber, and resin matrix, allowing direct contact with the brake disc, providing a high coefficient of friction and wear resistance. Nanoparticles are added to improve thermal conductivity and prevent localized overheating. The further reinforcing layer can withstand shear stress and disperse dynamic loads during braking. Second, the composite buffer system of the buffer layer can absorb dynamic impact loads during braking, reduce peak stress transmitted to the backing plate, and reduce high-frequency vibration through internal friction mechanisms, thereby extending the service life of the brake band body.
