Introductory Day
1 December 2008 | Venue: Maritim Hotel Berlin		  
   
   
Basics And Practice Of Automotive Transmissions
Aim

During the introductory day newcomers and participants with experience in other fields will get an overview of the most important transmission concepts. This introduction is also adequate for those who want to refresh their knowledge. Based on operating characteristics and driving resistance the function of automotive transmissions is defined and development objects are illustrated. A description of different transmission concepts in practice follows.

Starting with the concept of manual transmissions, automatic and continuously variable transmissions are explained. The introductory day will close with an examination of hybrid drive trains and power train management.

     
The Lecturers

The introductory day will be held by the Institute of Automotive Engineering of the Technical University of Braunschweig. The institute includes a competence centre for transmission technology with extensive experience in the development and evaluation of current transmission concepts.
