    The clutch is divided into three working states, that is, the non-linkage when the clutch is stepped on, the full linkage when the clutch is not pressed, and the semi-linkage when the clutch is partially pressed.

    Among the various parts of the clutch, the strength of the pressure plate spring, the friction coefficient of the friction plate, the diameter of the clutch, the position of the friction plate and the number of clutches are the key factors that determine the performance of the clutch. The greater the stiffness of the spring, the higher the friction coefficient of the friction plate, the larger the diameter of the clutch, and the better the clutch performance.

    The typical clutch working process can be divided into three processes: work, separation, and engagement.

  1. The working process. When the diaphragm spring is installed between the clutch cover and the pressure plate, the pressure on the pressure plate formed by the pre-compression deformation causes the main and driven parts of the clutch to be compressed, that is, the clutch is in an engaged state.
  2. Separation process. When the driver steps on the clutch pedal, the pedal moves to the left, the pushrod moves to the left, and the diaphragm spring separation plate is pushed to the left through the cylinder and working cylinder. Affected by this, the diaphragm spring uses the support pin fixed on the clutch cover as a fulcrum to move the big end to the right, and at the same time, the pressure plate is moved to the right by the action of the separation plate. Finally, there is a gap between the driven plate, the flywheel, and the pressure plate, and the clutch is separated. At this point, the clutch separation process ends.
  3. The joining process. When the driver releases the clutch pedal, the pedal returns to its original position under the action of the return spring, and at the same time drives the pushrod and the release bearing to return. That is, the movement of the operating mechanism during the engagement process is the reverse process of the separation process. When there is a reserved gap between the release bearing and the diaphragm spring separation plate and the diaphragm spring presses the pressure plate on the driven plate again, the engagement process ends and the clutch resumes the power transmission function.

    The clutch carries the power problems of automobiles, trucks, and other vehicles. It is also very important to find out and solve the problems of the clutch in our daily vehicle inspection work.
