Insert, manufacturing method of insert, electromagnetic clutch with insert and manufacturing method of electromagnetic clutch

The invention relates to an electromagnetic fan clutch of a vehicle, a manufacturing method of the electromagnetic fan clutch, an insert and a manufacturing method of the insert. The insert disclosed by the invention is used for the electromagnetic fan clutch comprising a bearing base and a bearing, wherein the outer surface of the insert is matched with the bearing base, the inner surface of the insert is matched with the bearing, and a clearance can be filled with the insert when the clearance between the bearing base and the bearing is changed. The manufacturing method of the insert, disclosed by the invention, comprises the following steps of: supplying raw materials of the insert; smashing the raw materials of the insert and adding a plasticiser for mixing; placing the compound into a mould for compression moulding; and placing the moulded insert into a sintering furnace for sintering. The electromagnetic fan clutch is formed by the insert disclosed by the invention. The manufacturing method of the electromagnetic fan clutch comprises the following steps of: embedding and casting the insert into the bearing base of a fan fixing plate and pressing the bearing to the inner circumference surface of the insert.
