A wet double clutch means that the double clutch is a large and small two sets of multi-plate clutches that are coaxially installed together. They are all installed in a closed oil chamber filled with hydraulic oil, so the wet clutch structure has better adjustment ability. And excellent hot melt, it can transmit relatively large torque without damage. However, due to the factors of layout and selection of friction materials, the dimensions of the wet dual-clutch are larger than that of the dry dual-clutch. The wet dual-clutch is stable and mature, not only can achieve fast and smooth shift work, but also at low speed because there is oil to help dissipate heat, so there will be no overheating.
The wet dual-clutch has a complex structure, relatively large volume and weight, and the manufacturing cost is much higher than that of the dry dual-clutch. At the same time, it is relatively time-consuming and laborious to maintain, and the cooling system must be replaced regularly.
The difference between wet dual-clutch and dry dual-clutch lies in the different working environments of the clutch plates. In addition, in terms of technical maturity and reliability, the wet dual-clutch is more stable to use because the clutch plate works in the hydraulic oil, and the oil has a certain heat dissipation effect. Due to poor heat dissipation, the dry dual-clutch is prone to the risk of high temperature or even ablation of the clutch disc in congested urban areas.
