Commercial vehicle brake discs are prone to thermal cracks and wear on the surface due to frequent braking, with a replacement cycle of only 3-6 months and an annual replacement cost of over 20000 yuan per unit. Daokedao adopts WC CoCr composite melting technology to melt a 1.5mm thick coating on the friction surface of the brake disc, with a hardness of HRC65 and a wear resistance four times that of the original cast iron brake disc. The friction coefficient is stable at 0.35-0.45. By using segmented cladding technology, thermal deformation of the brake disc is avoided, with a flatness error of ≤ 0.05mm/m and a dynamic balance accuracy of G2.5 level. The reinforced brake disc has undergone 100000 brake tests, with a wear of only 0.1mm and no thermal cracks. The replacement cycle has been extended to 18-24 months. After the application of 100 trucks by a logistics company, the annual cost of replacing brake discs was saved by 1.6 million yuan, the braking distance was shortened by 5%, and the driving safety was significantly improved. Suitable for commercial vehicles such as heavy-duty trucks, buses, and engineering machinery brake systems.
