Embodiment
Below in conjunction with embodiment the utility model is done further to describe.
Fig. 1, Fig. 2, Fig. 3 are the structural representations of two fast electromagnetism damping fan clutches.From figure, find out; Two fast electromagnetism damping fan clutches are to be provided with a rubber shock-absorbing land at the fan clutch mounting end; Mounting disc 12 is fixed on motor seam is installed; The flange 20 of mandrel 14 is cast for one through yielding rubber 13 and mounting disc 12, and yielding rubber 13 cast thickness are uniformity everywhere; The installation seam of mounting disc 12 is concentric with the external diameter of mandrel 14.Electromagnetic core 11 is supported on the mandrel 14 through rolling bearing 15, and the coil bundle of outputs 19 and is flexible coupling and 17 integrates, and fixes from electromagnetic core 11 rear ends and draws, and 17 the other end 18 of being flexible coupling is fixed on the motor; Rotation that drive plate 10 connects through key and mandrel 14 is fixed together; Fan mounting disc 2 is supported on the mandrel 14 through rolling bearing 3; Friction disk 5 is connected fan mounting disc 2 inboards through spring sheet 4; Fan 1 is installed on the double-screw bolt in fan mounting disc 2 outsides; Inlay a soft iron ring 6 in the outer ring of fan mounting disc 2, even number permanent magnet 7 is evenly distributed on a week (adjacent pole is opposite) on the soft iron ring 6, and the soft iron ring of responding in the drive plate 98 is corresponding with being embedded in; In fan mounting disc 2 outer rims symmetries two emergent sheets 16 are installed, the through hole on the emergent sheet 16 is corresponding with tapped hole on responding to drive plate 9.Fan mounting disc 2 Jian dresses fan, stationary spring 4, fixedly soft iron ring 6, fixing permanent magnet 7, the fixing sheet 16 of meeting an urgent need be in one; Friction disk 5 is corresponding with electromagnetic core 11 in drive plate 10 chambeies.
During work, engine drives damping mounting disc 12 connects 10 rotations of drive drive plate with mandrel 14 rotations, mandrel 14 through key; Drive induction drive plate 9 rotations that are fixed on drive plate 10 outer rims simultaneously, be embedded in the soft iron ring 8 in the induction drive plate 9, rotation relatively in the magnetic field that permanent magnet 7 and soft iron ring 6 form; Cutting magnetic line; Produce electric convolution in the soft iron ring 8, and form new magnetic field, under the reaction force of magnetic force; Induction drive plate 9 drives fan mounting disc 2 and 60%～50% rotating speed low speed rotation of fan 1 with mandrel 14 rotating speeds, plays the effect of low speed radiating and cooling.Along with engine water temperature is elevated to setting temperature (as 88 ℃); Engine ECU (or intelligent controller or coolant temperature switch) will give electromagnetic core 11 energisings; Electromagnetic core 11 generation magnetic fields to drive plate 10, and rotate friction disk 5 adhesives with drive plate 10 synchronously; Rotate synchronously with fan 1 thereby drive fan mounting disc 2, reach powerful cool effect.When water temperature drops to setting temperature (as 82 ℃); Engine ECU (or intelligent controller or coolant temperature switch) will tripping magnet core 11 power supply; Electromagnetic attraction disappears; Friction disk 5 breaks away from drive plate 10 under the spring-back force effect of spring sheet 4, fan mounting disc at this moment 2 again can be with the input speed low speed rotation of 60%-50% with fan 1.So go round and begin again, can make the water temperature of motor remain at the interior among a small circle running of optimal setting temperature (as 82 ℃-88 ℃).
When the increase and decrease suddenly of mounting disc 12 input power and bring impact force, or during the fan reaction force when connecting because of this clutch, yielding rubber 13 all can filter out the part impact force, thereby clutch and motor are played protective action.
