最初にブレーキディスクについて話しましょう。ブレーキディスク一般的に、ミドルベンチレーテッドディスク、パーフォレイテッドベンチレーテッドディスク、セラミックブレーキディスクに分けられます。名前が示すように、中央の換気ディスクは内部が中空であり、冷気が中央を通過して冷却することができます。それは一般的に前輪に使用されますブレーキディスク of civil vehicles. Perforated ventilating plate Perforated ventilating plate is to perforate the surface of the ventilating plate to ensure air circulation to the greatest extent and reduce heat attenuation. The perforated ventilating plate is one level higher than the ventilating plate. Ceramic ブレーキディスク are not ordinary ceramics, but reinforced composite ceramics composed of carbon fiber and silicon carbide at a high temperature of 1700 degrees. The weight of the ceramic disc is less than half of the ordinary cast iron disc. For example, the SLR MCIAREB with ceramic brakes has a front wheel brake disc with a diameter of 370mm but a weight of only 6.4 kg. The CL-CLASS, which uses ordinary ブレーキディスク, has a front disc diameter of 360mm but weighs up to 15.4 kg. Although the ceramic brake disc has excellent braking performance, its price is very expensive. For example, the optional price on high-performance sports cars of Porsche and Audi is more than 100,000 yuan.

ブレーキパッド again. Generally divided into asbestos type ブレーキパッド, semi-metal type ブレーキパッド, low metal type ブレーキパッド, ceramic type
ブレーキパッド, NAO (non-asbestos organic matter) type ブレーキパッド. The so-called asbestos-type ブレーキパッド are the earliest ブレーキパッド used at low cost and easy to manufacture. Early and common use. However, asbestos materials have been confirmed by the medical community to be carcinogens and their use is now banned. From the appearance of semi-metal ブレーキパッド, it has fine fibers and particles, which can be easily distinguished from asbestos type and NAO type. Compared with traditional brake materials, it mainly uses metal materials to increase the strength of the
ブレーキパッド.At the same time, temperature control and heat dissipation capabilities are also superior to traditional materials. However, because the material of the brake pad contains more metal components, especially in a low temperature environment, excessive braking pressure will cause the surface between the brake disc and the brake drum to wear and produce noise. From the appearance of low-metal ブレーキパッド, low-metal ブレーキパッド are somewhat similar to semi-metal
ブレーキパッド, with fine fibers and particles. The difference is that they have lower metal content than semi-metal ブレーキパッド. Ceramic ブレーキパッド The ブレーキパッド of this formula use new ceramic materials with low density, high temperature resistance and wear resistance. It has the advantages of no noise, no dust, no corrosion to the hub, long service life, and environmental protection, but the price is higher. As for the NAO (non-asbestos organic matter) ブレーキパッド, it should belong to the legendary artifact. It has the advantages of no dust pollution, low wear, low noise, and the service life is significantly extended.
