What does dual-clutch transmission mean?
1 Answers
Dual-clutch transmission (DCT) operates with two sets of clutches working simultaneously, where one set manages the odd-numbered gears and the other controls the even-numbered gears. Commonly abbreviated as DCT due to its dual-clutch design, many people simply refer to it as a dual-clutch transmission. The clutch, positioned between the engine and the transmission, acts as a 'switch' for power transfer from the engine to the transmission. It is a transmission mechanism capable of both transmitting and cutting off power, primarily ensuring smooth vehicle starts, reducing impact loads on transmission gears during gear shifts, and preventing overload in the drivetrain. In conventional vehicles, gear shifts are achieved through the engagement and disengagement of the clutch, which temporarily interrupts power transmission during the transition.
