Automobile brake pad manufacturers tell you that the structure of brake pads is not as simple as expected. What we see is a layer of conflicting data, a layer of iron. So, what are the data and functions of each layer?
1. Brake material: Brake material is undoubtedly the central part of the entire brake liner, and its conflict data formula directly affects braking function and brake comfort (without noise and oscillation). At present, the conflict data is divided into three main categories according to the formula: semi-metallic materials, Na materials (non-asbestos organic materials) and ceramic materials.
2. Insulation: During the braking process of the vehicle, because of the high-speed conflict between the brake liner and the brake disc, a lot of heat will be generated instantaneously. If the heat is transferred directly to the metal plate of the brake liner, the brake cylinder will overheat, and in severe cases, the brake fluid may create air resistance. Therefore, there is a insulation layer between the conflicting data and the metal backplane. The insulation layer should have the function of high temperature and high pressure resistance to effectively isolate the brake high temperature, and then maintain a stable braking distance.
3. Adhesive layer: Adhesive layer is used to bond conflict data and backplane, so its bonding strength is very important. It is necessary to ensure a strong connection between the rear plate and the collision data, and to provide a hard product to ensure the braking effect.
4. Backplane: The role of the backplane is to support the overall structure of the collision data, and transfer the braking force of the brake cylinder, and then can effectively connect the collision data of the brake liner and the brake disc. The backplane of the brake liner has the following characteristics: one. Comply with strict applicable norms; b. Ensure the safe operation of conflicting data and brake calipers; C. Backplane powder spraying technology; d. Environmental protection, rust prevention, applied.
5. Muffler film: The backplane is planned with muffler board, which can suppress oscillation noise and improve braking comfort.
The above is the automobile brake pad manufacturer to tell you the brake pad structure is very comprehensive analysis, everyone learned?
