    Using air to cool the clutch is called a dry clutch. In use, the clutch is required to be able to engage and disengage from the power lightly and freely, and the clutch should not be overheated when it works in a short-term half-clutch state. Because there is no resistance from oil, the dry clutch generally responds faster and has a larger occlusal force. Also because there is no cooling of the oil, dry clutches generally use exposed methods to dissipate heat. Compared with wet clutches, dry clutches differ mainly in these points.

    First, the life is short, and the cooling effect of the friction plates is not as good as that of a wet clutch due to the use of air cooling technology. Especially when the car is in the semi-clutch state for a long time in the city, the friction plates of the clutch work under high temperatures, and the life of the clutch will decrease.

    Second, the operability is poor. When using a dry clutch, frequent shifting operations are required. Unless the technology is excellent, the operability is worse than that of a wet clutch.

    However, dry clutch torque transmission is efficient. Because the dry clutch is not blocked by the clutch oil, it can control the power clutch lightly and freely and can work in the semi-clutch state in a short time, with a fast occlusal response and large occlusal force. But wet clutches are less articulate when it comes to transferring torque. Second, light weight and has good fuel economy. Since the dry clutch adopts air cooling, the oil pressure cooling system and the weight of the clutch oil are reduced, the bodyweight is simultaneously reduced, and the fuel economy is improved. Finally, the cost is low. Dry clutch cars are cheaper than wet clutch cars.
