Electromagnetic fan clutch

Abstract

The invention provides an electromagnetic fan clutch and belongs to the technical field of machinery. The electromagnetic fan clutch solves the problems that existing electromagnetic fan clutches areinconvenient to assemble and the like. The electromagnetic fan clutch comprises a swing arm shaft and a fan connecting disc, wherein a magnetic disc and a belt wheel are rotatably connected to the swing arm shaft; a coupling assembly and a coil iron core assembly are correspondingly arranged on two sides of the magnetic disc; the coil iron core assembly is fixedly connected to the swing arm shaftand is connected to a guide wire; the coupling assembly is connected to the belt wheel; the fan connecting disc is suspended out of the swing arm shaft and is fixedly connected to the magnetic disc; athrough hole penetrating through the front and back ends of the swing arm shaft is formed in the swing arm shaft; and a guide wire is arranged through the through hole. The electromagnetic fan clutchhas the advantages of being convenient to assemble, high in working stability, energy-saving and emission-reducing and the like.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to an electromagnetic fan clutch. Background technique [0002] When the engine is running, the radiator of the water tank is required to dissipate heat for the engine, and the radiator of the radiator is cooled by air. The radiator exchanges heat with the air outside the radiator, thereby transferring the heat in the radiator to the air. When the air flows, it brings cold air, so that the heat in the radiator of the water tank is transmitted to the air, so that the heat on the outer surface of the radiator of the water tank is continuously taken away, and the temperature of the water tank is cooled. When the cold water in the water tank passes through the engine, it passes through the heat exchange. Cool down the engine continuously. In order to improve the heat dissipation efficiency, it is necessary to carry out forced convection to the air outside the radiator, and generally a ...

AI Technical Summary

Problems solved by technology

After the gap between the pulley and the core part is enlarged, the compactness of the fan clutch will become poor, and the volume of the fan clutch will increase and occupy more space, which is not conducive to energy saving and emission reduction when installed on vehicles and mechanical devices; while the gap The increase is too small and will not significantly improve the ease of assembly

After marking on the wire, pulling the wire in place during installation shows that there is no excess wire being squeezed between the core part and the pulley, but if the marking is in the wrong position, it will reduce the convenience of the assembly process

For example, the connection between the mark and the wire and the core part is too short, and the mark position is in the threading hole, and the mark will not be observed during assembly, which leads to a mistaken belief that there is an extra wire between the core part and the pulley, and the wire is pulled hard. The connection with the core part is torn

Another example is that the connection between the mark and the wire and the core part is too long. Pulling out the wire may damage the wire. If the wire is not tightened, it is easy to trap the excess wire between the core part and the pulley.
