When the electromagnetic clutch is in operation, the on/off power of the coil is used to control the engagement and disengagement of the clutch. In the process of using the electromagnetic clutch, its working mode is to use the coil to open and close the current, which is used to achieve the purpose of the clutch. The electromagnetic clutch can also be referred to as an electromagnetic coupling. It uses the principle of electromagnetic induction and the friction between the inner and outer friction plates to form an electromagnetic clutch. The two rotating parts of the mechanical transmission system, that is, the main part, the follower and the pressing mechanism are basic structures for ensuring that the clutch is in an articulated state and capable of driving power, and the clutch control mechanism is mainly a clutch separating device.
Electromagnetic clutches are used in daily life, and electromagnetic clutches play an important role in manual transmissions. The electromagnetic clutch can be divided into three working states. One is the non-coupling state of the clutch, the other is the fully interlocked state of the clutch, and the other is the semi-coupling state of the partial stepping clutch. When the car is started, the platen is pressed tightly against the friction disc of the flywheel. In this case, the friction between the pressure plate and the friction plate is relatively large, and static friction must be maintained between the input shaft and the output shaft, and the rotation speed of the pressure plate and the friction plate are the same. The other is the semi-continuous state of the electromagnetic clutch. In a fully continuous state, the friction between the disc and the friction lining is less than the friction. At this point, the sliding friction state is between the clutch disc and the friction plate on the flywheel. The speed of the flywheel is greater than the speed of the output shaft, and the power transmitted by the flywheel is transmitted to the gearbox. The power, input and output of the electromagnetic clutch are allowed to have a difference in speed, that is, the speed difference of the clutch, so that proper power transmission can be achieved.
