| 摘 要： | 研究了代替52 CrMnBA钢用于重型汽车少片钢板弹簧的50 CrV钢的热处理工艺。研究结果表明，50 CrV钢板弹簧用PAG水溶性淬火介质淬火可明显提高淬透性和硬度均匀性；弹簧总成的疲劳寿命大于12万次，符合技术要求。道路试验表明，采用50 CrV钢制造的重型汽车少片钢板弹簧性能完全满足使用要求，且成本明显降低。

| Abstract: | The heat treating process of leaf-minimum plate spring of 50CrV steel instead of 52CrMnBA steel for heavy truck was investigared .The results reveal that the hardenability and hardness uniformity of 50 CrV steel plate spring may be significantly increased by quenching in a PAG aqueous solution , and that the fatigue life of plate spring assembly is as long as over 120 000 cycles , conforming with the technical requirement .Furthermore , the road test shows that the 50 CrV steel leaf-minimum plate spring for heavy truck has satisfactory performance , and is more low in production cost . |
