No. 12, A3, gucheng industrial park, longyao county, xingtai city, hebei province.The brake pad is not as simple as it looks. The brake pad looks very simple. A layer of friction material, a layer of iron, that's all we see. Is that really all? Sometimes what the eye sees is not all. In fact, a high-quality brake pad, its structure layer by layer, each layer plays an indispensable role. So, what are the materials and functions of each layer?
The following to the far brake pad as an example for everyone to introduce.
1. Friction material
Friction material is undoubtedly the core part of the whole brake pad, the formula of its friction material directly affects the brake performance and brake comfort of the friction pad (there is no noise and vibration).
At present, friction materials are mainly divided into three types according to the formula: semi-metal material, NAO material (no asbestos organic material) and ceramic material. Bosch brake pads use ceramic and low metal formulations to achieve low noise, low abrasive dust and high safety performance.
2. The thermal insulation layer
In the process of vehicle braking, because the brake pad and brake disc to carry out high-speed friction, instantaneous generation of a lot of heat, if the heat directly transferred to the brake pad on the metal back, it will cause overheating brake pump, serious may lead to brake fluid produced gas resistance. So there's an insulating layer between the friction material and the metal back. The heat insulation layer should be able to withstand high temperature and high pressure, effectively isolate the braking high temperature, so as to maintain a stable braking distance.
3. Adhesive layer
The adhesive layer is used to bond the friction material to the back plate, so its bonding strength is very important to ensure a reliable connection between the back plate and the friction material, providing a tough finished product to ensure braking effect.
4. Back
The function of the back plate is to support the overall structure of the friction material, and transfer the braking force of the brake sub-pump, so that the friction material of the brake pad and the brake disc joint efficiently. Bosch brake pads have the following characteristics:
A. meet strict durability specifications;
B. Ensure the safe operation of friction materials and brake calipers;
C. Powder coating technology for back plate;
D. Environmental protection, rust prevention and durability.
5. The mute
The back plate is designed with muffler, whose function is to suppress vibration noise and improve braking comfort.
Longyao xiangyuan co., LTD., established in January 2010, covers an area of 20,000 square meters and is located at no. 12, A3 zone, gucheng industrial park, longyao county, xingtai city, hebei province.
The company is strong, set scientific research, production, sales in one supporting service system, has a 2 tons induction furnace, advanced production technology, sophisticated processing equipment, strict process control, perfect testing means and high-quality staff team to ensure the high quality output of products, the annual output of 10,000 tons.
