When engine water temperature higher than first object temperature but lower than the second target temperature (as 88 DEG C) time, the loop of external circuit conducting low speed coil 12 makes it be energized, then low speed coil 12 produces electromagnetic force, low speed coupling piece 13 is attracted to overcome elastic force effect and disk 2 adhesive of low speed spring sheet, the circumferential position of fixed disk 2 and bearing housing 44, then the dragging plate 9 be connected with bearing housing 44 is with bearing housing 44 and disk 2 synchronous axial system.Now, dragging plate 9 drives fan initiatively land 5 acceleration rotation by the effect of attraction force between magnetic insert 10 and permanent magnet 11, then the rotating speed of fan initiatively 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 to cushion situation about accelerating instantaneously and damping, afterwards, fan passive coupling flange 6 and fan 3 is driven to accelerate gradually by himself elastic force.
When engine water temperature is higher than the second target temperature, the loop of external circuit conducting high speed coil 14 makes it be energized, then high speed coil 14 produces electromagnetic force, high speed coupling piece 15 is attracted to overcome elastic force effect and disk 2 adhesive of high speed spring sheet, the circumferential position in fixed disk 2 and adhesive portion 53, initiatively land 5 and disk 2 synchronous high-speed rotate to make fan.Same, now, the rotating speed of fan initiatively 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 to accelerate to gradually by himself elastic force to rotate at full speed, now, low speed coil 12 still keeps "on" position.
When engine water temperature dispels the heat because of fan 3 high speed rotating and reduces gradually, high speed coil 14 and low speed coil 12 progressively power-off, 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 is separated with disk 2 again with bearing housing 44.
In above full speed rotation process, when motor place breaks down suddenly and stops operating, the rotating speed of fan initiatively land 5 is lower than the rotating speed of fan passive coupling flange 6, 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 dislocation occurs for both, the elastic component 7 of strip is stretched.Magnetic part also can comprise the permanent magnet two being connected to the end of joint 52 that the axis around flange shaft 1 is uniformly distributed in the permanent magnet one on dragging plate 9 and is oppositely arranged with permanent magnet one, and permanent magnet one and permanent magnet two opposite pole are oppositely arranged.
And the technique scheme that this heavy card reverses 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 side and spring sheet is connected, on spring sheet relative 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 to be sheathed in flange shaft 1 and to be oppositely arranged with coupling piece.Its specific works process and above-mentioned high speed coil 14, high speed coupling piece 15 are identical with the working procedure of high speed spring sheet, repeat no more here.And bearing 4 can be common bearing, dragging plate 9 also can directly and flange shaft 1 be connected, then when hot-wire coil is not energized, can by dragging plate 9 by magnetic part drive fan 3 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 amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
