Typer af bremseskiver


Lad os først tale om bremseskiver.Bremseskiverer generelt opdelt i mellemventilerede skiver, perforerede ventilerede skiver og keramiske bremseskiver. Som navnet antyder, er den midterste ventilationsskive hul indvendig, og kold luft kan passere gennem midten for at køle ned. Det bruges generelt til forhjuletbremseskiver 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 bremseskiver 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 bremseskiver, 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.

Lad os tale ombremseklodser again. Generally divided into asbestos type bremseklodser, semi-metal type bremseklodser, low metal type bremseklodser, ceramic type bremseklodser, NAO (non-asbestos organic matter) type bremseklodser. The so-called asbestos-type bremseklodser are the earliest bremseklodser 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 bremseklodser, 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 bremseklodser.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 bremseklodser, low-metal bremseklodser are somewhat similar to semi-metal bremseklodser, with fine fibers and particles. The difference is that they have lower metal content than semi-metal bremseklodser. Ceramic bremseklodser The bremseklodser 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) bremseklodser, 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.
