Transmission Engineering Summit in Beijing

31.05.2016 // The Chinese market is interested in all pioneering transmission technologies, with requirements that are meanwhile just as demanding as those made in Europe. This is the conclusion reached by IAV after attending the Transmission Symposium in Beijing. The engineering partner used the event to present its unique methods for the synthesis of drives, transmissions and e-motors, together with an innovative concept for hybrid transmissions.

The Transmission Symposium in Beijing (April 28 and 29) is the most important congress of its kind in China. IAV has been an exhibitor at the event for eight years; during this period, it has closely monitored the development of China’s car market. “Today the market requirements in China can be compared with those in Europe”, reports Erik Schneider, head of the Hardware Development for Transmission and Hybrid Systems department at IAV. “This was clearly obvious also in the large number of transmission technologies being presented in Beijing. As in Europe, all modern variants have their own particular merits, with a broad range of technologies available for the world’s largest car market.

Focus on electrifying the powertrain

The country has put special emphasis on expanding e-mobility, so that China is currently seeing great demand for transmissions that can be integrated in electric and hybrid vehicles. A paper presented by IAV introduced its concept for an innovative hybrid transmission. Named “IAV Power Hybrid”, the transmission is seamlessly integrated in the e-motor, offering more functionality while saving package and costs.

IAV’s unique methodical approach in this field shows how ideal vehicle concepts can be quickly and reliably defined, combining computerized synthesis of the powertrain, transmission and e-motor. The best possible solution is thus available early on in the development process. “This systematic, structured method is one of IAV’s unique selling propositions”, says Schneider.
During the congress, IAV also presented its highly integrated dual-clutch transmission consisting of various modules for clutch, hydraulics and wheel set. “There is great demand for new technologies in Beijing”, summarizes Schneider. “That’s why this year’s conference once again offered a good opportunity to discuss the key trends in this field, including in particular efficiency, NVH and cost reduction.”
