- 摘要:
- 通过对制动鼓失效机理的分析，采取合理的材料化学成分配比结合熔炼工艺来提高铸件强度、改善石墨形
态，以增强导热性能，同时通过结构优化和预埋网状芯骨保证铸件的致密性，减少铸件缺陷，从而整体提高制动鼓的强
度和致密性。 研制的高强度双金属制动鼓，可满足国内高承载性重卡的需求，提高企业的经济效益和社会效益。
Based on the analysis of the failure mechanism of brake drum, the reasonable material chemical composition ratio and the smelting process were adopted to improve the casting strength and graphite morphology, so as to enhance the thermal conductivity. At the same time, the compactness of the casting was guaranteed by structural optimization and embedded mesh core bone, and the defects of the casting were reduced, so as to improve the strength and compactness of the brake drum. The results show that the high strength bimetallic brake drum can meet the domestic demand of high load-bearing heavy trucks and improve the economic and social benefits of enterprises.
