What are the differences between dry dual-clutch and wet dual-clutch?

[DiAnna]

The differences between dry dual-clutch and wet dual-clutch are: 1. Different structures: The dry dual-clutch consists of an active part, a driven part, a compression mechanism, and an operating mechanism; the wet dual-clutch consists of a hydraulic pump, lubricating fluid, cooling pipes, and an external cooling system. 2. Different linkage media: The dry dual-clutch relies on air as the medium, while the wet dual-clutch relies on oil as the medium. The basic transmission principles of both dry and wet dual-clutch transmissions are the same, both utilizing two clutches for alternating operation. Continuously variable transmissions (CVT), automatic transmissions (AT), and DSG wet dual-clutch transmissions all have clutches composed of hydraulic cylinders, steel plates, and friction plates. They all use computer-controlled solenoid valves to direct fluid flow, controlling the operation of the hydraulic cylinders. The hydraulic cylinders then compress multiple steel plates and friction plates to engage the clutch. When the oil returns, the steel plates and friction plates separate under the force of the springs.
