Improved clutches should meet the following main requirements: 

1. Smooth and gentle engagement to ensure smooth vehicle start-up. 

2. Quick and complete disengagement for easy gear shifting and engine starting. 

3. Possess adequate reserve capacity to ensure the transmission of maximum engine torque while preventing drivetrain overload. 

4. The rotational inertia of the driven components should be as small as possible to reduce shifting shock. 

5. Good heat dissipation capability. During vehicle operation, relative sliding between the clutch's driving and driven components generates frictional heat. If this heat cannot be dissipated in a timely manner, it will severely affect the clutch's operational reliability and service life. 

6. Light and easy operation to reduce driver fatigue.
