What is the difference between dry clutch and wet clutch?
2 Answers
Here are the differences between dry clutch and wet clutch: 1. Dry clutch and wet clutch are distinguished based on dual-clutch transmissions. Dual-clutch transmissions are currently the most popular type of transmission. The structure of this transmission is similar to that of a manual transmission, but it has two sets of clutches that control odd and even gears separately. 2. The clutch plates of a dry clutch are not immersed in transmission oil. The clutch plates of this type of transmission rely on air passing through the chassis for cooling. The clutch plates of a wet clutch transmission are immersed in transmission oil, and the clutch plates of this type of transmission rely on the transmission oil for cooling. 3. Wet clutch transmissions can withstand greater torque than dry dual-clutch transmissions, while dry clutch transmissions have faster gear shifting speeds than wet dual-clutch transmissions. 4. The stability and reliability of wet clutch transmissions are better than those of dry clutch transmissions. 5. Dry clutch transmissions are generally paired with smaller-displacement turbocharged engines that have lower power output, while wet clutch transmissions are usually paired with more powerful turbocharged engines.
I've been driving for over a decade and have tried many cars. The difference between dry and wet clutches is quite noticeable. A dry clutch operates in a dry environment without oil lubrication, giving a more direct feel. Gear shifts during acceleration are crisp. When driving a small manual car to work, you might occasionally experience slipping or shuddering at startup, especially in winter or rainy conditions. The clutch plates wear out faster, possibly requiring inspection or replacement after tens of thousands of kilometers—it's cost-effective but requires more attention. On the other hand, a wet clutch is immersed in oil for cooling and lubrication. Driving a friend's automatic car felt much smoother, with silent gear shifts and no foot fatigue in traffic jams, making it more suitable for city driving and fuel efficiency. However, the downside is the additional oil system, which complicates maintenance and adds weight. It's ideal for daily drivers to reduce fatigue. The choice depends on driving habits—for commuting, a wet clutch is recommended for convenience and ease.
