Jenis-jenis cakram rem

Mari kita bicara tentang rem cakram dulu.Cakram remumumnya dibagi menjadi cakram berventilasi tengah, cakram berventilasi berlubang, dan cakram rem keramik. Sesuai namanya, cakram ventilasi tengah berlubang di dalam, dan udara dingin dapat melewati bagian tengah untuk mendinginkan. Hal ini umumnya digunakan untuk roda depanrem cakram 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 rem cakram 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 rem cakram, 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.
