摘　　要：随着石油能源的枯竭和环境要求的不断提高,人类对于汽车的节能减排越来越重视,而变速箱是汽车传动系统中的重要组成部分,对于整车的燃油消耗及排放有着很大的影响。文章以湿式DCT设计,从速比范围的选择,同步器的选择和控制,油泵的选择和应用,离合器的优化,润滑系统的优化等几个方面,介绍了在DCT设计开发过程中,为实现节能减排,所做的措施。Under the threat of depleting petroleum resources and global environment issues, more aggressive attentions are paid on vehicle emission and fuel consumption. As one of the most significant components of power train system, the transmission to a great extent influences the emission performance and fuel efficiency. In this article, some effective designs of DCT transmission on emission improvement and fuel efficiency are introduced, including ratio definition, synchronizer＇s selection and controlling, and pump, clutch, lubrication system optimization.
