When this heavy card reverses the work of damping magnetic clutch assembly, flange shaft 1 is connected with the clutch end of motor, can drives flange shaft 1 around himself axis rotation during engine operation, simultaneously, disk 2 also synchronously rotates with flange shaft 1.
When engine water temperature lower than the first object temperature, during as 82 ℃, low speed coil 12 and the equal no electric circuit of high speed coil 14, do not produce electromagnetic force, low speed coupling piece 13 and high speed coupling piece 15 are connected by low speed spring sheet and high speed spring sheet and bearing housing 44 and adhesive section 53 respectively, fan initiatively between land 5 and disk 2 and between bearing housing 44 and disk 2 all in separated state.Fan initiatively land 5 is only accepted transmission of power by bearing 4 from flange shaft 1 place, slowly rotate, and when rotating by define fan initiatively between land 5 and fan passive coupling flange 6 circumferential position pressure spring drive fan passive coupling flange 6 and the fan 3 that is connected mutually with fan passive coupling flange 6 with its slow rotation.
When engine water temperature higher than the first object temperature during but lower than the second target temperature (as 88 ℃), the loop of external circuit conducting low speed coil 12 makes its energising, low speed coil 12 produces electromagnetic force, attract low speed coupling piece 13 to overcome elastic force effect and disk 2 adhesives of low speed spring sheet, the circumferential position of fixed disk 2 and bearing housing 44, the dragging plate 9 be connected with bearing housing 44 is synchronizeed rotation with bearing housing 44 and disk 2.Now, dragging plate 9 drives initiatively land 5 acceleration rotations of fan by the effect of attraction force between magnetic inserts 10 and permanent magnet 11, the rotating speed of fan active land 5 is higher than the rotating speed of fan passive coupling flange 6, misplace between the two and relatively rotate, the pressure spring that compression is positioned at cavity is between the two cushioned and damping with the situation that moment is accelerated, afterwards, drive fan passive coupling flange 6 by himself elastic force and fan 3 accelerates gradually.
When engine water temperature during higher than the second target temperature, the loop of external circuit conducting high speed coil 14 makes its energising, high speed coil 14 produces electromagnetic force, attract high speed coupling piece 15 to overcome elastic force effect and disk 2 adhesives of high speed spring sheet, the circumferential position of fixed disk 2 and adhesive section 53, make fan initiatively land 5 and disk 2 synchronous high-speeds rotations.Same, now, the rotating speed of fan active land 5 is higher than the rotating speed of fan passive coupling flange 6, misplace between the two and relatively rotate, compression is positioned at the pressure spring of cavity between the two, and pressure spring plays the effect of buffering and damping, afterwards, drive fan passive coupling flange 6 and fan 3 by himself elastic force and accelerate to gradually at full speed and rotate, now, low speed coil 12 still keeps "on" position.
When engine water temperature, because of fan 3 high speed rotating, dispel the heat and while reducing gradually, high speed coil 14 and low speed coil 12 progressively cut off the power supply, high speed coupling piece 15 and low speed coupling piece 13 are returned to initial position respectively under the elastic force effect of high speed spring sheet and low speed spring sheet, and fan initiatively land 5 separates with disk 2 again with bearing housing 44.
In above full speed rotation process, when the motor place breaks down suddenly and while stopping operating, initiatively the rotating speed of land 5 is lower than the rotating speed of fan passive coupling flange 6 for fan, and both dislocation and same compression pressure spring, carry out bumper and absorbing shock.
In addition, elastic component 7 also can be strip and several elastic component 7 is uniformly distributed around the axis of flange shaft 1, and the two ends of elastic component 7 are connected with the side of fan active land 5 and fan passive coupling flange 6 respectively.When both misplace, the elastic component 7 of strip is stretched.Magnetic part also can comprise that the axis around flange shaft 1 is uniformly distributed in permanent magnet one on dragging plate 9 and the permanent magnet two of the end that is connected in joint 52 that is oppositely arranged with permanent magnet one, and permanent magnet one and permanent magnet two opposite poles are oppositely arranged.
And the technique scheme of this heavy card torsion damping magnetic clutch assembly also can be applicable on two fast magnetic clutch assemblies, its electromagnetic clutch mechanism can comprise hot-wire coil, coupling piece and spring sheet, the side of coupling piece one side and spring sheet is connected, on spring sheet with respect to the opposite side of coupling piece and fan initiatively land 5 lean and be connected with this fan active land 5 by the bolt worn on it, hot-wire coil is sheathed on flange shaft 1 and with coupling piece and is oppositely arranged.Its specific works process is identical with the working procedure of above-mentioned high speed coil 14, high speed coupling piece 15 and high speed spring sheet, repeats no more here.And bearing 4 can be common bearing, dragging plate 9 also can be directly and flange shaft 1 be connected,, when hot-wire coil is not switched on, can drive fan 3 by magnetic part by dragging plate 9 and slowly run.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various modifications or supplement or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
