Pag-usapan muna natin ang tungkol sa mga disc ng preno.Mga disc ng prenosa pangkalahatan ay nahahati sa gitnang may bentilasyon na mga disc, butas na may bentilasyon na mga disc, at ceramic preno disc. Tulad ng ipinahihiwatig ng pangalan, ang gitnang bentilasyon ng disc ay guwang sa loob, at ang malamig na hangin ay maaaring dumaan sa gitna upang palamig. Karaniwan itong ginagamit para sa pangulong gulongmga disc ng preno 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 mga disc ng preno 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 mga disc ng preno, 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.
Pag-usapan natin ang
mga pad ng preno again. Generally divided into asbestos type mga pad ng preno, semi-metal type mga pad ng preno, low metal type mga pad ng preno, ceramic type
mga pad ng preno, NAO (non-asbestos organic matter) type mga pad ng preno. The so-called asbestos-type mga pad ng preno are the earliest mga pad ng preno 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 mga pad ng preno, 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
mga pad ng preno.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 mga pad ng preno, low-metal mga pad ng preno are somewhat similar to semi-metal
mga pad ng preno, with fine fibers and particles. The difference is that they have lower metal content than semi-metal mga pad ng preno. Ceramic mga pad ng preno The mga pad ng preno 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) mga pad ng preno, 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.
