摘　　要：变速器是汽车的核心子系统之一,现阶段自动变速器的技术指标和验证方法以国外技术经验为主。但中国车辆的使用习惯及道路、交通状况与其它国家有很大不同,对于变速器最为关键的可靠性指标,需以中国使用条件下的情况进行验证。运用负载因子分析了中国法规循环和国外法规循环工况负载构成,通过分析国外已有的自动变速器耐久循环片段,重构了基于中国法规循环工况的自动变速器耐久循环,为自动变速器耐久循环的开发探索了新的途径。Transmission is one of the core subsystems in the vehicle and at present the verification method mainly comes from foreign technical experience. However, the vehicles working conditions, roads traffic conditions in China are very different from that in foreign countries, so the auto-transmission should be verified under China road conditions. In this paper, China＇s regulatory cycle and foreign regulatory cycle are compared with load factor analysis method and the new durability test cycle applicable to China＇s road conditions is reconstructed with the analysis of regulatory cycle and referring test cyclee.
