Description
Technical field
The present invention relates to a kind of magnetic clutch, particularly relate to a kind of torsional spring type magnetic clutch.
Background technique
The working principle of traditional electrical magnet clutch is: main shaft and driving disc pivot joint, driven disc and main shaft are fixed, adhesive dish is between driving disc and driven disc, adhesive dish is connected by spring sheet with driving disc, electromagnetic core parts are relative with adhesive dish gap, the adhesive that adhesive dish and driven disc are controlled in energising by electromagnetic core parts and power-off with separate, and then control the transmission of moment of torsion between driving disc and driven disc, thereby the rotation that realizes main shaft is clutch function with stopping.But in order to realize the abundant transmission of moment of torsion, between electromagnetic core parts and adhesive dish, To Axial Force Needed is larger, therefore the required electric current of electromagnetic coil is larger, thereby it is more to cause energy of electric automobile to consume, the volume of electromagnetic core parts is also relatively large, in some occasion, inconvenience is installed, even needs to change original automobile train system.
In view of above-mentioned technical problem, the applicant also once applied for the Chinese invention patent (not yet open at present) of " a kind of variable-speed water pump and control strategy thereof " in the early stages, propose a kind of utilization, between belt pulley and driven shaft, torsion spring has been set, utilized holding tightly and unclamping transmission train power of torsion spring.But because the axial legs of torsion spring need to be through the arc slotted hole arranging on driven shaft sidewall, extend into again in the groove arranging on adhesive dish, although the arc slotted hole arranging provides enough the sphere of activities to torsion spring axial legs, but still there is certain defect: in non-normal working situation, if when the angle that driven shaft rotates is greater than the number of degrees of arc slotted hole, the interference of driven shaft and torsion spring action will be caused, the lighter affects the normal work of variable-speed water pump, severe one directly makes this variable-speed water pump scrap, thereby affect the normal operation of vehicle, therefore reliability deficiency, on the other hand, this complicated structure, manufacture cost is higher.
Summary of the invention
The object of the invention is to solve the problems of the technologies described above, provide that a kind of clutch To Axial Force Needed is less, the required electric current of electromagnetic coil is also less, energy of electric automobile consumption is lower, it is little to wear and tear, reliability is high, long service life, be convenient to install, simple in structure, lower-cost a kind of magnetic clutch.
For realizing this object, technological scheme disclosed by the invention is:
This torsional spring type magnetic clutch, comprise a main shaft 11, housing 1 with main shaft 11 middle part pivot joints, a follower 8 affixed with main shaft 11 one end, be fixed on the electromagnet assembly 2 on housing 1, one with the driving wheel 6 of follower 8 pivot joints, one adhesive dish 3, one wavy spring 10, one torsion spring 5, described adhesive dish 3 comprises adhesive dish flange 31 unlike the prior art, the adhesive dish breach 33 arranging on adhesive dish sleeve 32 and adhesive dish sleeve 32, wavy spring 10 is between adhesive dish flange 31 and housing 1, in the time of no electric circuit, one side end face of adhesive dish flange 31 is relative with electromagnet assembly 2 gaps, opposite side end face and driving wheel 6 are close near a side end face of electromagnet assembly 2, two free ends of described torsion spring 5 are drawn respectively the first pin 51 and the second pin 52, described follower 8 comprises that diameter is less than the follower breach 82 arranging on the follower sleeve 81 of adhesive dish sleeve 32 diameters and its flange, torsion spring 5 is positioned at outside adhesive dish sleeve 32, follower sleeve 81, and under free state, its internal diameter is greater than the external diameter of follower sleeve 81, and its first pin 51 stretches in adhesive dish breach 33, and its second pin 52 stretches in follower breach 82.Adopt this technological scheme, power transmission between train is frictional force by circumferential enclasping force but not radially, therefore the required axial force of clutch is very little, thereby the required electric current of electromagnetic coil is also very little, energy of electric automobile consumption is very low, wearing and tearing are very little, reliability is higher, longer service life, be more convenient for installing, structure is simpler, cost is lower.
Further, between wavy spring 10 and housing 1, also install back-up ring 9 additional.Adopt this technological scheme, intercepted on the one hand direct contact the between wavy spring 10 and housing 1, reduce wearing and tearing, facilitate on the other hand installment and debugging and later maintenance.
Further, driving wheel 6 arranges circular groove near a side end face of electromagnet assembly 2, and friction ring 4 is set in circular groove.Adopt this technological scheme, increased area of contact, increased frictional force, be conducive to improve the transmission efficiency of train power, reduce wearing and tearing, and be conducive to later maintenance and reparation, improve the life cycle of product.
Further, the sectional shape of torsion spring 5 is rectangle.Adopt this technological scheme, when torsion spring is held tightly or torsion spring silk can be not overlapped when tensioner, free resilience while conveniently unclamping, and also the area of contact of torsion spring and driven shaft more increases with respect to other shapes, is conducive to the transmission of moment of torsion.
Further, the rotation direction of torsion spring 5 is consistent with the sense of rotation of driving wheel 6.Adopt this technological scheme, be conducive to the dispersion of active force, very large as egg shell compressive resistance, but anti-tension is very little.The rotation direction of torsion spring 5 torsion spring identical with driving wheel sense of rotation only can be held tightly not can tensioner, can the thin-walled of adhesive dish sleeve 32 not risen broken.
Further, between driving wheel 6 and follower 8, pass through double row bearing 7 pivot joints.Adopt this technological scheme, driving wheel 6 is less with follower 8 diaxon axis relativity shifts, improves whole clutch traveling comfort.
Further, main shaft 11 middle parts are by shaft connecting bearing and housing 1 pivot joint.Because rotating shaft and bearing unite two into one, assembly of whole parts, adopts this technological scheme to reach to reduce installation procedure, reduces labor intensity, improves the object of bearing quality, and whole parts precision, performance and used life are all improved.
Further, the second pin 52 radially points to torsion spring circumcircle center of circle direction and extends a segment distance afterwards again along being concentric with the circumferential of torsion spring circumcircle and pointing to torsion spring rotation direction and extend a segment distance, and then radially dorsad torsion spring circumcircle center of circle direction extend one section of same distance, last again along torsion spring circumcircle circumferentially, and dorsad torsion spring rotation direction extend a segment distance; The shape of the follower breach 82 correspondingly, arranging on the flange of follower is corresponding with the shape of the second pin 52 and can hold the second pin 52 and stretch into.Adopt this technological scheme can make torsion spring coordinate with follower more firm, reliability is higher.
Below in conjunction with accompanying drawing, clutch of the present invention is described further.
