How Often Should the Oil in a Dry Dual-Clutch Transmission Be Changed?
1 Answers
Dry dual-clutch transmission oil is typically changed every three years or after driving 60,000 kilometers. The internal structure of a dry dual-clutch transmission is relatively complex, requiring high-quality transmission lubricants. Therefore, it is recommended to use the manufacturer's specialized oil for replacement. Dual-clutch transmissions are divided into dry and wet types. Both types operate on similar principles, with two clutches taking turns to work. However, the connection medium between the clutch's driving and driven plates differs. Dry dual-clutch transmissions rely on air, while wet dual-clutch transmissions use oil. Dry and wet dual-clutch transmissions share similarities but also have distinct differences, each with its own advantages and disadvantages. The primary difference lies in the working environment of their clutch plates. In wet dual-clutch transmissions, the clutch plates are immersed in transmission fluid, whereas in dry dual-clutch transmissions, the clutch plates directly contact the engine flywheel. In terms of technological maturity and reliability, wet dual-clutch transmissions are more stable because the clutch plates operate in hydraulic oil, which provides some cooling effect. Dry dual-clutch transmissions, due to their poor heat dissipation, are prone to overheating of the clutch plates in congested urban areas, posing a risk of burning or erosion.
