New energy commercial vehicles have a large weight and high braking frequency, while traditional brake discs have a lifespan of only 30000 to 40000 kilometers and high replacement costs. Daokedao adopts WC CoCr nanocomposite melting technology, with a brake disc friction surface coating hardness of HRC68 and wear resistance five times that of the original cast iron disc. After 150000 brake tests, the wear amount is only 0.15mm. By optimizing the coating structure, the heat dissipation efficiency is improved by 35%, avoiding high-temperature thermal degradation, and the friction coefficient is stable at 0.35-0.45. For the brake discs of new energy commercial vehicles with a diameter of 420mm, the flatness error is ≤ 0.05mm/m, and the dynamic balance accuracy reaches G2.5 level, suitable for energy recovery braking systems. After the application of 50 new energy trucks by a logistics company, the brake disc replacement cycle has been extended to 120000 to 150000 kilometers, saving an annual replacement cost of 400000 yuan and reducing brake failure downtime by 90%. This plan has also passed the ECE R13 brake safety certification, ensuring the safe operation of commercial vehicles and helping new energy logistics fleets reduce costs and increase efficiency.
