Drivers such as fuel consumption and CO₂ emissions reduction, as well as enhanced driving comfort, have led to a strong evolution of power train module designs over the past years. Dual clutch systems appear to be a major technical trend contributing to this mutation. The clutch system is consequently becoming more complex with additional features and new parts. Lots of internal components are then exposed to more severe conditions while in the meantime a higher reliability and longer vehicle mileage is required. Dual Clutch Transmissions require an optimized and reliable engineering approach combining strong technology expertise, advanced calculations and testing. New optimized bearing solutions have to be engineered to reach the highest robustness level in order to face severe operating conditions and achieve extended lifetime in a compact and light package. These new designs not only improve global DCT efficiency and reliability but set as well a new standard in noise reduction.
