Алдымен тежегіш дискілер туралы сөйлесейік.Тежегіш дискілерәдетте орта желдеткіш дискілерге, перфорацияланған желдеткіштерге және керамикалық тежегіштерге бөлінеді. Атауынан көрініп тұрғандай, ортаңғы желдеткіш дискінің іші қуыс, ал суық ауа ортасынан өтіп, салқындауы мүмкін. Ол әдетте алдыңғы доңғалаққа қолданыладытежегіш дискілер 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 тежегіш дискілер 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 тежегіш дискілер, 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.
Туралы сөйлесейік
тежегіш алаңдар again. Generally divided into asbestos type тежегіш алаңдар, semi-metal type тежегіш алаңдар, low metal type тежегіш алаңдар, ceramic type
тежегіш алаңдар, NAO (non-asbestos organic matter) type тежегіш алаңдар. The so-called asbestos-type тежегіш алаңдар are the earliest тежегіш алаңдар 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 тежегіш алаңдар, 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
тежегіш алаңдар.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 тежегіш алаңдар, low-metal тежегіш алаңдар are somewhat similar to semi-metal
тежегіш алаңдар, with fine fibers and particles. The difference is that they have lower metal content than semi-metal тежегіш алаңдар. Ceramic тежегіш алаңдар The тежегіш алаңдар 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) тежегіш алаңдар, 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.
