Parlons d'abord des disques de frein.Disques de freinsont généralement divisés en disques ventilés intermédiaires, disques ventilés perforés et disques de frein en céramique. Comme son nom l'indique, le disque de ventilation central est creux à l'intérieur et l'air froid peut passer par le milieu pour se refroidir. Il est généralement utilisé pour la roue avantDisques de frein 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 Disques de frein 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 Disques de frein, 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.
Parlons de la
les plaquettes de frein again. Generally divided into asbestos type les plaquettes de frein, semi-metal type les plaquettes de frein, low metal type les plaquettes de frein, ceramic type
les plaquettes de frein, NAO (non-asbestos organic matter) type les plaquettes de frein. The so-called asbestos-type les plaquettes de frein are the earliest les plaquettes de frein 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 les plaquettes de frein, 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
les plaquettes de frein.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 les plaquettes de frein, low-metal les plaquettes de frein are somewhat similar to semi-metal
les plaquettes de frein, with fine fibers and particles. The difference is that they have lower metal content than semi-metal les plaquettes de frein. Ceramic les plaquettes de frein The les plaquettes de frein 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) les plaquettes de frein, 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.
