Is the Boyue dual-clutch wet or dry?
2 Answers
The Boyue dual-clutch is a dry dual-clutch. Below are the specific introductions to dry and wet transmissions in automobiles: 1. Working Principle: The working principles of the two types of transmissions are basically the same, both utilizing two clutches for alternating operation. The difference lies in the medium connecting the driving and driven plates. Wet dual-clutch transmissions mainly rely on oil, while dry dual-clutch transmissions primarily 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 transmission oil absorbing heat by immersing 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.
I've been driving the Boyue 1.8T Flagship for three years, and I specifically researched the transmission when buying the car. This car uses a 7-speed dual-clutch transmission with a wet structure, where the clutch plates are immersed in oil for cooling. The wet design is particularly suitable for SUVs, as frequent gear changes in traffic jams won't cause overheating as easily as with dry clutches. I commute daily in the city and often encounter traffic jams, but the transmission has never shown any jerking, and the fuel consumption is around 9L/100km. With wet clutches, you need to change the transmission fluid regularly—about every 60,000 kilometers, costing around 800 yuan—but the durability is much better than with dry clutches. On my last road trip, I drove through mountain roads with continuous downshifts, and the power delivery remained very smooth.
