Is a car DCT an automatic transmission?
1 Answers
Yes, a car DCT is an automatic transmission, which refers to a dual-clutch transmission. The principle of DCT is based on two sets of manual transmissions, where adjacent gears are typically arranged alternately on the two sets of gears. Two clutches separately control the connection and disconnection of the two sets of gears with the engine. The dual-clutch automatic transmission is a mechanical automatic transmission that retains all the advantages of AMT. However, its power transmission is achieved through two clutches connecting two input shafts, with adjacent passive gears alternately meshing with the gears on the two input shafts. By coordinating the control of the two clutches, it can achieve gear ratio changes without interrupting power transmission, thereby reducing shift time and effectively improving shift quality.
