What's the Difference Between Automatic Transmission and Dual Clutch?
2 Answers
The differences between automatic transmission and dual clutch: 1. Different operation methods: Automatic transmission does not require the driver to manually shift gears, as the vehicle will automatically select the appropriate gear based on driving speed and traffic conditions; Dual clutch allows for automatic shifting by simply pressing the accelerator, or manual shifting. 2. Different principles: Automatic transmission uses a computer to control hydraulic oil to push pistons for gear shifting based on throttle position, vehicle speed, and throttle opening; Dual clutch is equipped with two clutches, each fixed to control corresponding gears. Taking dual clutch as an example, its function is to eliminate the power transmission stagnation during clutch shifting, ensuring that the engine's power is transmitted to the wheels without delay, and it is mostly used in sports cars.
The automatic transmission has a torque converter inside, which transfers power like through a flow of water, making the gear shifting process smooth and gentle. As for the dual-clutch transmission, it directly uses two sets of gear sets working in relay, with one set operating while the other prepares the next gear. This structure allows for ultra-fast gear shifts without power interruption. However, the dual-clutch transmission is prone to overheating in congested areas because the clutch plates are directly connected. I prefer the smooth feeling of the automatic transmission, especially when driving steadily to pick up and drop off kids at school; young people might favor the crisp acceleration and strong push-back feeling of the dual-clutch transmission.
