What is the working principle of a wet dual-clutch?

[StHolden]

The working principle of a wet dual-clutch: A wet clutch uses hydraulic pressure for clutch engagement, controlling the transmission of driving force during the processes of clutch separation, full engagement, and even under relative rotation conditions. Similar to the slip control in automatic transmissions, it is easier to control smaller driving forces in a sliding state, but continuous engagement pressure is required to maintain the engaged state. Unlike dry clutches, wet clutches primarily rely on hydraulic operation and are generally used in automatic transmissions and continuously variable transmissions (CVTs) that require higher smoothness. Additionally, compared to torque converters, they provide better slip suppression during driving, thereby improving fuel economy.
