What is the difference between dry and wet dual-clutch transmissions?

[LaKira]

1. The medium connecting the driving disc and the driven disc is different. Wet dual-clutch transmissions mainly rely on oil, while dry dual-clutch transmissions primarily depend on air. 2. The working principles differ. The clutch of a wet dual-clutch transmission is installed in a sealed oil chamber filled with hydraulic oil, whereas a dry dual-clutch transmission lacks a hydraulic system and transmits torque through the friction plates of the driven disc. Additional information: Wet clutches are called wet because they are lubricated by engine oil. The engine oil provides cooling and lubrication between the clutch cage and the mating components.
