Differences Between Dry and Wet Dual-Clutch Transmissions
1 Answers
Dry and wet dual-clutch transmissions differ in the following aspects: 1. Cooling Methods: Dry dual-clutch transmissions rely on air cooling for heat dissipation; Wet dual-clutch transmissions are immersed in oil, offering higher cooling efficiency. 2. Operational Differences: Dry clutches use manual transmission friction plates, featuring high mechanical transmission efficiency but more complex operation and higher failure rates; Wet clutches employ automatic transmission oil-immersed friction plates, with lower mechanical transmission efficiency but easier operation and lower failure rates. Dual-clutch transmissions are not suitable for frequent starts, prolonged low-speed driving, or stop-and-go traffic conditions, as they are prone to overheating, which can lead to malfunctions. Once the vehicle's computer issues a warning, it is essential to stop immediately to cool down the transmission.
