What does wet dual-clutch mean?
3 Answers
Wet dual-clutch refers to a dual-clutch transmission where the clutch plates are immersed in transmission oil. The wet dual-clutch relies on the oil for cooling, with transmission oil added to the sealed clutch assembly, supplemented by a radiator. A wet dual-clutch transmission must include a hydraulic pump, lubricating fluid, cooling pipes, and an external cooling system. Wet clutches primarily operate hydraulically and are generally used in automatic transmissions and continuously variable transmissions that require higher smoothness. Wet clutches are divided into single-plate and multi-plate types. When used as a starting device for vehicles, multi-plate wet clutches are mostly employed. The multi-plate design increases the friction area, ensuring small diameter with high torque capacity.
As an automotive enthusiast, a wet dual-clutch transmission is a dual-clutch system design where the clutch plates operate immersed in transmission fluid, which helps dissipate heat and prevent overheating issues. This design is particularly suitable for high-performance vehicles like sports cars or SUVs, as it can handle high torque output, enabling faster and smoother gear shifts during acceleration or track driving. Compared to dry dual-clutch transmissions, it is slightly heavier but more reliable and durable. Maintenance requires regular oil changes, which may be slightly more costly, but in the long run, it reduces the risk of shuddering. Personally, I love its performance during spirited driving—its gear shifts are responsive and stable, making it an ideal choice for those who seek driving pleasure.
I'm a regular driver who often uses automatic transmissions. A wet dual-clutch system is where the clutch plates of the transmission are immersed in lubricating oil for cooling. It feels more comfortable to drive compared to dry clutches, especially in traffic jams or during long drives, as it's less prone to overheating and jerking. I remember one long trip where the gear shifts were as smooth as flowing water, making it ideal for daily family use or off-road needs. Maintenance isn't overly complicated—just an oil change every few tens of thousands of kilometers. The cost is slightly higher, but it's much more reliable and durable. This design is common in high-power vehicles, like some luxury sedans, offering you peace of mind and ease of use.
