In order to achieve the objective of further reducing CO2 emissions and fuel consumption of powertrains, the improvement of the efficiency of the entire system - engine, transmission, driveline - is one measure the automotive industry is focusing on. Transmissions still have high potentials to improve their efficiency, that applies for conventional as well as electrified or pure electric powertrains. 

 

A main contributor to transmission efficiency are the losses inside the gearbox. The total losses are a combination of mechanical losses due to friction and splashing losses, due to oil movement and its interaction with the moving parts as gears and shafts. The overall mechanical losses are caused by various transmission components due to friction in their contacts: gears, roller bearings, sealings and clutches/synchronizers.

 

AVL has developed a simulation solution to accurately calculate and analyze mechanical and hydrodynamic transmission losses, and to evaluate the impact of their improvements on emissions and fuel consumptions by connecting these results with office and real time drive cycle simulations. That way it is possible to also consider the influence of real driving cycles and the driver behavior for the assessment of the transmission component design measures.

 

AVL cordially invites you to join the one of our webinars on October 17, 2017.
