What is the Difference Between Wet and Dry Transmissions?

[MacDamian]

Here are the specific differences between dry and wet transmissions in automobiles: 1. Medium: The working principles of dry and wet transmissions are fundamentally the same, both utilizing two clutches for alternating operation. The difference lies in the medium connecting the driving and driven discs. Wet dual-clutch transmissions primarily rely on oil, whereas dry dual-clutch transmissions mainly depend on air. 2. Basic structure: The two sets of clutch plates in a wet clutch are housed in a sealed oil chamber, with the heat absorbed by the transmission oil that soaks the clutch plates. In contrast, the friction plates of a dry clutch do not have a sealed oil chamber and rely on air cooling for heat dissipation.
