Resource-Efficient Process Chains for the Production of High-Performance Powertrain Components in the Automotive Industry

Abstract This paper focuses on process chains for power train components of passenger cars and heavy duty vehicles. In the project “Powertrain 2025” particular attention is being paid to increase resource efficiency manufacturing reduce energy demand during service life. detail cylinder liners are equipped with an adapted geometry topography which reduces friction losses. Process chassis investigated optimized in order manufacturing, life maintenance. addition, drive shafts adjusted. By eliminating hard machining, saved losses reduced by laser machining microstructures. Furthermore, micro dimples applied vane pumps, leads a tribological improvement thus enhances their behaviour. Moreover, system architecture planning developed ecologically parameters calculated. For final consideration, calculation software enables calculate main consumption processes carbon footprint expected A weight reduction powertrain 4.5 kg per vehicle potential annual saving 13,073 MWh obtained.
