演讲人介绍：

Mr. Rudolph Baumann 自2005年起在上海担任自动变速箱应用工程经理。

他主要致力于变速箱在中国的本土化，并建立起相应的工程环境。同时，根据中国汽车生产商的需要，对采埃孚变速箱进行改型设计。

Mr. Rudolph Baumann毕业于慕尼黑工业大学，主修机械工程。 大学毕业后，他主要从事于航天工业的燃料电池研发工作。于1991年加入ZF Getriebe GmbH。成为步进式自动变速箱和无级变速箱测试和发展部门的主管。

演讲摘要：

目前，全球有80%左右的乘用车制造商都已着手进行横向前置驱动的汽车设计工作。由于市场，尤其是一些新兴市场对小型车的偏好直接导致这些汽车生产量的稳步增长，因此，在接下来的几年内，这个百分比会进一步提高。

我们所论证的这一项研究，将对各种变型的行星变速器和双离合变速器进行比较。

面向未来对横置发动机车辆的需求，双离合变速器和带变矩器的行星变速器都表现强劲。从安装空间和成本角度而言，行星变速器比双离合变速器有着更显著的优势。从能源消耗方面来说，它们相对于电动车有一些微不足道的优势，但是液力变矩器的扭矩倍增功能却能使汽车在启动和加速动力方面得到补偿。

Speaker Introduction:

Mr. Rudolph Baumann works since 2005 as application engineering manager for automatic transmissions in Shanghai. His tasks in China are localization of transmissions, build-up of engineering environment and the adjustment of ZF-transmissions to the vehicles of the Chinese OEMs.

After the study of mechanical engineering at the Technical University of Munich he worked until 1991 in the field of fuel cell development for the space industry. In 1991 he joined the ZF Getriebe GmbH and became supervisor in the testing department for the development of step-controlled automatic transmissions as well as for continuous variable automatic transmissions (CVT).

Abstract of Speech:

Currently, almost 80% of all passenger cars manufactured worldwide are built as a front-transverse driveline design. As production figures are increasing steadily, it is expected that this percentage will even rise over the next few years, since the market growth is the result of preference for compact vehicles, particularly in emerging markets.

Within the scope of a study, miscellaneous variants of planetary and dual clutch transmissions were compared.

Both dual clutch transmissions as well as planetary transmissions with torque converters have a strong presence among future requirements for use in vehicles powered by transverse engines. Planetary transmissions have distinct advantages compared to dual clutch transmissions in terms of installation space, and especially in view of costs. In terms of consumption,they only have minor drawbacks compared with electrically actuated dual clutch transmissions, although this is compensated by their starting and acceleration dynamics, due to the torque multiplication functionality of the torque converter.
