What is the lifespan of a 7-speed wet dual-clutch transmission?
1 Answers
Under normal circumstances, the designed lifespan of a 7-speed wet dual-clutch transmission is at least 300,000 kilometers, with most capable of reaching 250,000 kilometers. Additional information: 1. Types of dual-clutch transmissions: Wet dual-clutch transmission and dry dual-clutch transmission. 2. Differences between the two: The two sets of clutch plates in a wet dual-clutch are housed in a sealed oil chamber, where the transmission oil absorbs heat by immersing the clutch plates; whereas the friction plates in a dry dual-clutch lack a sealed oil chamber and rely on air cooling for heat dissipation. 3. Function of dual-clutch transmissions: Ensures smooth vehicle starts, reduces impact loads on transmission gears during gear shifts, and prevents overloading of the drivetrain.
