What are the advantages and disadvantages of dry and wet dual-clutch transmissions?
1 Answers
Dry dual-clutch and wet dual-clutch transmissions share similarities but also have differences. Neither is inherently superior to the other, as each has its own strengths and weaknesses. Below is a comparison of their advantages and disadvantages: 1. Dry-type has inferior heat dissipation compared to wet-type: Due to poorer heat dissipation, dry dual-clutch transmissions face higher risks of clutch plate overheating or even burning in congested urban areas. In this aspect, wet dual-clutch transmissions demonstrate higher technological maturity. 2. Dry-type offers higher power transmission efficiency: Wet dual-clutch transmissions rely on hydraulic fluid. The wet-type clutch plates are immersed in transmission fluid, which provides better heat dissipation. From the perspective of technological maturity and reliability, wet dual-clutch transmissions are more stable in operation since the clutch plates work in hydraulic oil that aids in cooling. However, wet dual-clutch transmissions have more complex structures, higher manufacturing costs, and slightly lower power transmission efficiency compared to dry-type. Additional information: Dual-clutch transmissions are categorized into dry and wet types. Both types operate on fundamentally similar principles, featuring two clutches that alternate in operation.
