Is the Gearbox of the Boyue Dry or Wet?
2 Answers
The gearbox of the Boyue is dry, meaning it is a dry-type gearbox. The differences between dry and wet clutches are as follows: 1. Their working principles are generally the same, with both having two sets of clutches working simultaneously—one managing odd-numbered gears and the other managing even-numbered gears. 2. The main difference between the two types of clutches lies in the connection medium between the driving disc and the driven disc. A dry dual-clutch transmits power through air, while a wet dual-clutch uses oil. 3. The characteristics of a dry clutch include lower cost and higher efficiency, but the drawbacks are that it is more complicated to operate and prone to damage. 4. The advantages of a wet clutch are simpler operation and lower failure rates, while the disadvantages are higher cost and lower efficiency compared to a dry clutch.
I've repaired quite a few Geely Boyue vehicles, which use a wet dual-clutch transmission. This type of transmission relies on oil to cool the friction plates, offering excellent heat dissipation. It doesn't overheat or get damaged easily during traffic jams or frequent stop-and-go driving, making it more durable and reliable than dry transmissions. Dry transmissions use air cooling, which is lighter but has poor thermal management and is prone to issues when climbing hills. The Boyue opts for a wet transmission because it suits the daily driving needs of an SUV and has strong load-bearing capacity. However, wet transmissions are slightly heavier, which can slightly affect fuel consumption, and require regular transmission oil changes. It's recommended to inspect and service the transmission every 60,000 kilometers to extend its lifespan and ensure driving safety. Geely has optimized the tuning in its design, making the driving experience smooth with minimal jerking, which is ideal for family use.
