Compact Seven- And Ten-Speed Dual-Clutch Transmissions

The ongoing trends of downsizing and downspeeding require new transmission concepts with large ratio spread and number of gears in order to simultaneously improve fuel consumption and launch behaviour. Using a systematic synthesis process, FEV has developed a new generation of dual-clutch transmissions with seven and ten gears, the xDCT family. Through a combination of the features ‘gear generation’ and ‘supported shift’, these concepts set a new benchmark regarding number of gears per mechanical complexity.
