Transmissions in mobile machines - conference

A large range of professionals from Germany and abroad with a background in transmission development and gear design in mobile machinery will be meeting again on 27 and 28 June 2018. In the past, this event has attracted considerable attention and interest and set the stage for some fascinating debate. Within the framework of the Transmission Congress (Dritev), the philosophy of networking and exchanging views across industry sectors at the World Conference Center (WCCB) in Bonn fosters a stimulating discussion amongst attendees and speakers, which is highly appreciated on both sides.

Reduce carbon emissions in mobile machinery and make their use more fuel-efficient through improved transmission and drive technology

The 5th international VDI Congress “Transmissions in mobile Machinery“ will present the latest solutions that are aimed at reducing fuel consumption and CO2 emissions in mobile machinery. Current legislation call for the efficient translation of technological visions and ideas to successfully bring them to series production stage. Requirements towards transmission and drive sytems will be addressed as well as their integration into the vehicle. Likewise, topics like subsystems and more efficient transmission components will be covered.  

Topics at the International Expert Meeting 

The following topics will be discussed at the VDI Congress “Transmissions and Driveline Technology in mobile Machinery“:

  • Visions and vehicle concepts in agricultural and construction machinery 
  • Driveline and transmission concepts
  • Systems and topologies 
  • Digitisation
