摘　　要：离合器从动盘总成存在的主要问题是减振盘疲劳强度不足,为了提高离合器的疲劳寿命,使其在±2000N·m高扭矩条件下,疲劳寿命达到350万次以上。根据失效分析和对国外离合器剖析结果,按材料和工艺的不同组合制定了3种试验方案,并进行对比试验。试验结果表明,3种试验方案的离合器产品在±2000N·m高扭矩台架试验条件下,疲劳试验寿命均达到350万次以上,寿命较改进前大幅提高。结构改进后,选用08钢能满足产品技术性能要求,而且经济性良好。This paper presents the problem of clutch driven plate assembly is the insufficient fatigue strength of ratainer plate in order to increase the fatigue life of clutch,make it that reach3500000times under the condition of±2000N·m torque.According to failure analysis and results of foreign clutch anatomy,3experiment scenarios are established base d on different material and process combinations,and also comparison and tests are carried out .The results show that fatigue life of all clutches under conditions of±2000N·m torque for3experiment scenarios can reach move than3500000times.After improvement of structure,08steel can meet product technical requirement and show economical performance.
