Description
Technical field
The invention belongs to field of mechanical technique, and it is total to be related to a kind of adjustable speed damping automobile engine electromagnetic fan clutch
Into.
Background technology
Vehicle needs radiator of water tank to radiate to engine when running work, and radiator of water tank is further through air-cooled
It radiates.Radiator of water tank carries out heat exchange with the air outside radiator of water tank, so as to by the heat in radiator of water tank
Amount is transferred in air, and when air flow brings cold air, and the heat in radiator of water tank is made to be transmitted always into air, so as to
Heat on radiator of water tank outer surface is constantly taken away, feed-tank cooling, the cold water in water tank passes through heat when passing through engine
It exchanges again constantly to engine cooling.In order to improve radiating efficiency, it is necessary to which the air outside to radiator carries out forced convertion, generally
In one side of radiator, fan is set.
Chinese patent literature data, which discloses, proposes a kind of heavy truck torsional vibration damping electromagnetic clutch assembly [application number：
CN201310400895.3；Notification number：103437878B], be sheathed on including flange shaft and successively disk on the outside of flange shaft,
