Embodiment 1

[0044] Such as figure 1 , figure 2 , Figure 10 As shown, an insert 1 of the present invention is used for an electromagnetic fan clutch including a bearing seat 2 and a bearing 3. The insert 1 is in the shape of a ring, and the left and right end faces of the insert 1 are connected with the outer surface. There is an annular right-angle groove 5a, an annular rectangular groove 5b is opened in the middle of the outer surface of the insert 1, and four axially distributed rectangular through grooves 5c are opened on the outer surface of the insert 1, and the rectangular through grooves 5c are evenly distributed in the insert 1 on the circumference of . The outer peripheral surface of insert 1 is in contact with bearing seat 2, and the inner surface of insert 1 is matched with bearing 3. The material of insert 1 is seamless steel pipe No. 20, and its expansion coefficient is 12 microns per meter per degree. The bearing steel The expansion coefficient is 12.5 microns per mete...

Embodiment 2

[0047] Such as image 3 , Figure 4 , Figure 12 As shown, an insert 1 of the present invention is used for an electromagnetic fan clutch including a bearing seat 2 and a bearing 3 . The insert 1 is in the shape of a ring, and a thread groove 6 is processed on the outer surface of the insert 1 . The outer peripheral surface of insert 1 is in contact with bearing seat 2, and the inner surface of insert 1 is matched with bearing 3. The material of insert 1 is seamless steel pipe No. 20, and its expansion coefficient is 12 microns per meter per degree. The bearing steel The expansion coefficient is 12.5 microns per meter per degree, the expansion coefficient of aluminum is 24 microns per meter per degree, and the expansion coefficient of insert 1 is close to that of bearing 3. The material of the above-mentioned insert 1 can also be a seamless steel pipe with an expansion coefficient of 11.25 microns per meter per degree, or a seamless steel pipe with an expansion coefficient o...

Embodiment 3

[0050] Such as Figure 5 , Figure 6 , Figure 13 As shown, an insert 1 of the present invention is used for an electromagnetic fan clutch including a bearing seat 2 and a bearing 3. The insert 1 is in the shape of a ring, and four through holes 7 are opened on the outer surface of the insert 1. The through holes 7 are formed after the groove 4 passes through the ring body of the insert 1. The four through holes 7 are evenly distributed along the circumference of the insert 1, and the axes of the two opposite through holes 7 coincide, and the axes of the two through holes 7 are adjacent to each other. parallel. The outer peripheral surface of the insert 1 is in contact with the bearing seat 2, and the inner surface of the insert 1 is matched with the bearing 3. The material of the insert 1 is iron-based powder metallurgy material, and its expansion coefficient is 12.25 microns per meter per degree, and the bearing steel The expansion coefficient is 12.5 microns per meter pe...

Abstract

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.

Description

technical field [0001] The invention relates to a vehicle component and a manufacturing method, in particular to an automobile electromagnetic fan clutch and a manufacturing method thereof, an insert and a manufacturing method thereof. Background technique [0002] The fan blades of the electromagnetic fan clutches on the market are fixed on the fan fixed plate with bolts, and the fan fixed plate is rotatably connected with the transmission shaft through bearings. When working, when the water temperature of the automobile engine reaches the set value, the electromagnet core coil of the electromagnetic clutch is energized and connected with the suction plate, and at the same time drives the magnet fixed plate fixedly connected with the suction plate to rotate, and passes through the magnet fixed plate. The magnet and the soft magnet embedded in the fan fixed plate are attracted at intervals, so that the fan fixed plate operates with a lag relative to the magnet fixed plate to...
