摘　　要：文章根据国内外双离合自动变速器(DCT)技术研究应用现状,提出了一种新型DCT的传动方案,并描述其工作原理及结构特点;根据整车参数的要求对各挡传动比进行合理的分配,在满足整体尺寸紧凑的情况下设计行星轮系和其他各齿轮重要参数,并完成各类齿轮的空间布置;最后,对此传动方案建立评价指标体系,进行分析评价,并就其应用前景进行展望。This paper puts forward a transmission scheme for a new type of dual clutch transmission（DCT）,and describes its working principle and structural characteristics based on the DCT research status at home and abroad.Proper distribution of ratios at each gear is made based on the technical parameters requirements of the complete vehicle.With the satisfaction of the compact space requirements,the planetary gear system and some other gears parameters are designed and the space distribution for each gear is made.Evaluation criteria system for this transmission scheme is also established and its future applications are prospected.
