毕业论文（设计） 题 目： DSG变速器 学 院： 汽车学院 专 业： 汽车电器工程师 班 级： 06级 6班 学 号： 0612140399 学生姓名： 指导老师： 刘昭霞 完成日期： 2010年3月10号  摘 要 随着世界汽车对汽车动力性、 经济性排放提出了更高要求DSG ，英文全称Direct-Shift Gearbox，翻译成中文就是“直接换挡变速器”。用更通俗的话来说就是“双离合器 机械式半自动变速器”DSG（Direct-Shift Gearbox）变速器是目前世界上最先进的、具有革命性的变速器系统，大众汽车在2002年于德国沃尔夫斯堡首次向世界展示了这一技术创新。新一代DSG变速器采用了双离合器和6个前进档的传统齿轮变速器作为动力的传送部件，主要与高扭矩的发动机配合使用。大众汽车公司投入1.5亿欧元在卡塞尔的大众工厂，用于制造DSG变速器，该工厂最大日产能为1000台。  Abstract Along with the world automobile to the automobile power, the efficiency, the emissions and the maneuverability proposed a higher request, regarding the automobile maneuverability, the automobile divides into the manual transmission gearbox and the automatic transmission simply, this I must elaborate am in the automatic transmission newest achievement----DSG transmission gearbox. DSG, English full title Direct-Shift Gearbox, translates Chinese is “shifts gears directly the transmission gearbox”.With a more popular speech is “the double clutch mechanical type manumitted transmission”. DSG (Direct-Shift Gearbox) the transmission gearbox was in the present world most advanced, has the revolutionary transmission gearbox system, the populace automobile fort has for the first time demonstrated this technological innovation in 2002 in German Wolfe the Si to the world.The new generation of DSG transmission gearbox has used the double clutch and 6 front motion traditional gear transmission gearbox takes the power the transmission part, main and high torque engine coordination use.Volkswagenwerk invests 150,000,000 euros in the Kassel populace factory, uses in making the DSG transmission gearbox, this factory maximum daily production can be 1000.
