Abstract
The invention discloses a vehicle electromagnetic fan clutch which mainly comprises a raw flexible magnet and permanent magnets, wherein the raw flexible magnet is arranged in the circumference surface of the inner cavity of a fan fixing disk, and the permanent magnets are uniformly distributed on the outer circle of a magnet fixing disk. When the vehicle electromagnetic fan clutch works, the permanent magnets on the outer circle of the magnet fixing disk generate magnetic field attractive force relative to the raw flexible magnet in the surface of the inner cavity of the fan fixing disk to ensure that radical forces acting on a bearing mutually counteract, thus the damage to respective transmission bearings due to eccentric wear is eliminated. The position of the raw flexible magnet in the surface of the inner cavity of the fan fixing disk and the positions of the permanent magnets on the outer circle of the magnet fixing disk are far away from the positions of respective bearings, high-temperature heat generated by magnetic field eddy current during the work is respectively radiated through rotating heat radiating fins on the magnet fixing disk and heat radiating sheets on the fan fixing disk through cyclone, thus lubricating grease in the bearings is not diluted by high temperature to overflow, the transmission bearings are prevented from being early worn and damaged, the service life of the vehicle electromagnetic fan clutch is prolonged, and the maintenance cost for a user is lowered.
Description
(1) technical field: the present invention relates to the automobile electromagnetic engaging and disengaging gear; Be specifically related to a kind of automobile electromagnetic fan clutch.
(2) background technique: the driving of automobile electromagnetic fan clutch connects in the prior art, mainly be connected with and be spacing on the end face of magnet fixed disc and be connected with some block permanent magnets by fan fixed disk inner chamber circumferential ring cover, the magnetic field suction that the soft magnet that is provided with in the resonator end surface in fan fixed disk produces forms axially mutual significantly pulling force drive fan fixed tray drive fan blade and rotates, to realize the radiating and cooling to the engine operation water temperature.Because described magnet fixed disc all is to be connected driving with transmission shaft by drive bearing with fan fixed disk.It exists not enough: the one, act on larger axis on magnet fixed disc and the fan fixed disk respectively to mutual pulling force, the roller or the ball that have caused being equipped with in the drive bearing inner and outer rings rolling rail separately are in the eccentric wear state always, cause bearing seal sternly not cause to place lubricant grease in it to leak outside and release, aggravated the eccentric wear wearing and tearing of drive bearing separately and damaged; The 2nd, being provided with in the resonator end surface in the described fan fixed disk distributes on the position of soft magnet and the magnet fixed disc end face is connected with the position of some block permanent magnets, all nearer at a distance of the position of drive bearing separately, drive bearing is given in the very fast conduction of heat of high temperature that is produced by the magnetic field electric convolution during work, in the relatively poor automobile electromagnetic fan clutch inside of ventilation and heat condition, very easily make the lubricant grease of sealing in the drive bearing be subjected to the heat of high temperature dilution and overflow, equally also aggravated the drive bearing breaking-up of wearing and tearing prematurely.Usually damage when needing maintain and replace in drive bearing wearing and tearing, safeguard that the Chang Yin of producer removes and installs inconvenience, the electromagnetic fan clutch of integral body is scrapped again changed, in the working life of having reduced the automobile electromagnetic fan clutch, increased user's maintenance cost significantly.
(3) summary of the invention: at the deficiency of above-mentioned prior art existence, the object of the present invention is to provide a kind of automobile electromagnetic fan clutch, reduce the wearing and tearing breaking-up of drive bearing and the rising of temperature when being intended to work, to realize improving the working life of automobile electromagnetic fan clutch, reach the maintenance cost that reduces the user.
For achieving the above object, the technological scheme of a kind of automobile electromagnetic fan clutch of the present invention is achieved in that and comprises that mainly fan fixed disk inner chamber circumference is the magnet fixed disc that the spacer ring cover is connected with; It is to be provided with soft magnet in the inner chamber circumferential surface of described fan fixed disk; It is corresponding to be some block permanent magnets that spacing is connected with on described soft magnet and the magnet fixed disc outer round surface; In near the fan fixed disk that is connected with drive bearing, on the resonator end surface circumference, be the spacing distribution and be connected with the heat insulation and heat control intake opening; In near the fan fixed disk that is provided with soft magnet, on the resonator end surface circumference, be the spacing distribution and be connected with the heat insulation and heat control exhaust vent.
When implementing technique scheme, the present invention can distribute on the end face of described magnet fixed disc one or both sides and be connected with some radiating fin.
When implementing technique scheme, the present invention can also distribute on the corresponding fan fixed disk cylindrical that is provided with soft magnet and be connected with some radiating fin.
The present invention is by taking said structure, during work, be distributed on the magnetic field suction that the soft magnet in the relative fan fixed disk surface of internal cavity of some block permanent magnets on the magnet fixed disc cylindrical produces, the radial force that acts on thus on the drive bearing is separately cancelled out each other, realized that the roller or the ball that are equipped with in the drive bearing inner and outer rings rolling rail separately are in normal rolling lubrication, have eliminated the breaking-up that drive bearing causes lubricant grease to leak because of the eccentric wear wearing and tearing in the prior art.Be connected with the position of permanent magnet owing to distributing on position that is provided with soft magnet in the fan fixed disk inner chamber circumferential surface and the magnet fixed disc cylindrical, all away from the position of drive bearing separately, when the heat of high temperature that produces when the magnetic field electric convolution in the work conducts to fan fixed disk and magnet fixed disc, the one, in fan fixed disk, be spacing heat insulation and heat control outlet and inlet hole and the drive bearing be connected with that distribute on the resonator end surface circumference respectively and realize two-layer interval thermal resistance, prevented of the conduction of most of heat to its bearing; The 2nd, by the rotation of radiating fin on the magnet fixed disc end face, make extraneous cooling air suck automobile electromagnetic fan clutch inside, by the heat insulation and heat control exhaust vent the in time outside eddy flow of its inner heat of high temperature that produces is discharged and carry out radiating and cooling effectively by the heat insulation and heat control intake opening on the interior resonator end surface of fan fixed disk; The 3rd, by the rotation of radiating fin on the fan fixed disk cylindrical, the heat of high temperature that is connected with the generation of soft magnet position in the disk body is carried out the whirlwind radiating and cooling at any time; Reduce the operating temperature of drive bearing separately significantly, guaranteed that the lubricant grease in the drive bearing is not separately overflowed by the high temperature dilution, prevented the drive bearing breaking-up of wearing and tearing prematurely effectively.Improve the working life of automobile electromagnetic fan clutch, reduced user's maintenance cost.
