What is the difference between dry and wet transmissions?

[RubyLynn]

Transmission dry and wet difference is in the clutch active and driven disc connection medium is different: transmission dry is by air; transmission wet is by oil. Dry dual-clutch and wet fundamentally speaking, the basic transmission principle of these two transmissions is the same, both use two clutches to work in turn. Dry dual-clutch transmission does not have a hydraulic system, its torque is transmitted through the friction plate of the driven disc; wet dual-clutch transmission clutch is installed in a sealed oil chamber filled with hydraulic oil. Wet dual-clutch transmission because its clutch plate is soaked in oil, the oil plays a certain cooling effect, so the performance is more stable when in use.
