The first DCT to reach production was the Easidrive automatic transmission introduced on the 1961 Hillman Minx mid-size car. In car and truck applications, the DCT functions as an automatic transmission, requiring no driver input to change gears.
The design is often similar to two separate manual transmissions with their respective clutches contained within one housing, and working as one unit.
Schematic of a DCT (using two identical clutches located on the axis of the flywheel)Ī dual-clutch transmission ( DCT) (sometimes referred to as a twin-clutch transmission) is a type of multi-speed vehicle transmission system, that uses two separate clutches for odd and even gear sets. Not to be confused with Double clutching (technique).
