Description
Technical Field
The invention belongs to the technical field of machinery, and relates to an electromagnetic fan clutch.
Background
When the engine works, the radiator needs to radiate heat for the engine, and the radiator radiates heat through air cooling. The water tank radiator exchanges heat with air outside the water tank radiator, thereby transferring heat in the water tank radiator to the air. When the air flows, cold air is brought, so that heat in the radiator of the water tank is always transmitted to the air, heat on the outer surface of the radiator of the water tank is continuously taken away, the water tank is cooled, and cold water in the water tank is continuously cooled for the engine through heat exchange when the cold water passes through the engine. In order to improve the heat dissipation efficiency, forced convection of air outside the radiator is required, and a fan is generally disposed at one side of the radiator.
The Chinese patent literature data discloses and proposes an electromagnetic fan clutch [ application number: CN201410101075.9; bulletin number: 103939495B ], including dead axle, the driving disk, fan fixed disk and iron core part, fan fixed disk rotationally installs on dead axle or driving disk, there is the actuation dish through elastic disc fixed mounting on the right-hand member face of fan fixed disk, the driving disk rotationally installs on the dead axle, there is the clearance between the right-hand member face of left end face and actuation dish of driving disk, still rotationally install the belt pulley on the dead axle, belt pulley and driving disk fixed connection, still fixed mounting has iron core part on the dead axle, iron core part is located between driving disk and the belt pulley, the recess or the wire guide of axial setting have been seted up on the dead axle, the wire of iron core part can be worn out from recess or wire guide.
When the iron core component is not electrified, the attraction disc is separated from the transmission disc, the fan fixing disc is not fixed with the transmission disc, the fan fixing disc does not synchronously rotate with the belt pulley, and the fan does not rotate. When the iron core component is electrified, the attraction disc is attracted to the transmission disc, so that the fan fixing disc is fixed on the transmission disc, the fan fixing disc and the belt pulley synchronously rotate, and the rotation and heat dissipation of the fan are accelerated.
When the fan clutch is assembled, the bracket is sleeved on the fixed shaft, the belt pulley is installed and fixed on the fixed shaft, the iron core component is sleeved on the fixed shaft, and the wires on the iron core component are synchronously penetrated into the wire holes while the iron core component is installed. Because the entrance of the wire guide is arranged between the belt pulley and the iron core component, and the reserved space between the belt pulley and the iron core component is small, the fixing position of the belt pulley and the transmission disc can shield the sight line, so that the wire is very inconvenient to penetrate into the wire guide. In order to prevent the wire from being torn off in the installation process, particularly the connection part with the iron core component, the wire is not tensioned in the installation process, so that a part of redundant wire is easy to be extruded between the iron core component and the belt pulley, the iron core component cannot be installed in place, the wire is easy to damage, the belt pulley cannot rotate due to severe clamping of the belt pulley, the iron core component is required to be taken apart, the wire is rearranged and reinstalled, and the fan clutch assembly process is complicated and inconvenient.
In order to facilitate assembly of the fan clutch, it is conceivable to make the gap between the pulley and the core member large or to mark the wire. After the gap between the belt pulley and the iron core component is made large, the structural compactness of the fan clutch is poor, the fan clutch occupies more space when the size is increased, and the fan clutch is mounted on a vehicle and a mechanical device, so that energy conservation and emission reduction are not facilitated; the too small increase of the clearance does not obviously improve the convenience of assembly. After marking the wire, pulling the wire in place during installation indicates that no excess wire is being squeezed between the core member and the pulley, but the location of the marking if made in error would reduce the ease of the assembly process. For example, the connection between the mark and the wire and the iron core component is too short, the mark is not observed when the mark is positioned in the threading hole, and the mark is mistakenly considered to be redundant between the iron core component and the belt pulley, and the connection between the wire and the iron core component is torn by pulling with force. For example, if the mark is too long to the connection between the wire and the iron core component, the wire is pulled out of the position where the wire is torn, and the redundant wire is easy to stay between the iron core component and the belt pulley without tensioning the wire.
