Jenis cakera brek - Berita - Ningbo Kunpeng Auto Electric Co., Ltd.

Mari kita bincangkan cakera brek terlebih dahulu.Cakera breksecara amnya dibahagikan kepada cakera berventilasi tengah, cakera pengudaraan berlubang, dan cakera brek seramik. Seperti namanya, cakera ventilasi tengah berlubang di dalam, dan udara sejuk dapat melewati tengah untuk menyejuk. Ia biasanya digunakan untuk roda depancakera brek 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 cakera brek 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 cakera brek, 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.

Mari kita bercakap mengenaiPAD brek again. Generally divided into asbestos type PAD brek, semi-metal type PAD brek, low metal type PAD brek, ceramic type PAD brek, NAO (non-asbestos organic matter) type PAD brek. The so-called asbestos-type PAD brek are the earliest PAD brek 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 PAD brek, 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 PAD brek.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 PAD brek, low-metal PAD brek are somewhat similar to semi-metal PAD brek, with fine fibers and particles. The difference is that they have lower metal content than semi-metal PAD brek. Ceramic PAD brek The PAD brek 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) PAD brek, 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.
