Embodiment
To develop simultaneously embodiment below in conjunction with accompanying drawing, describe the present invention.
As shown in figure 1 and 2, the invention provides a kind of high pulling torque magnetic clutch, this magnetic clutch comprises magnet case 1, splined shaft 2, sleeve 3, bearing 4, V-type friction plate 5, the armature 6 being with V-type friction plate, upper spring seat 7, spring 8, lower spring cup 9 and drive bevel gear 10, and peripheral unit is driven wheel of differential 11 and driven shaft 12;
Magnet case 1 endoporus of magnetic clutch has spline to coordinate with splined shaft 2 to install, magnet case 1 periphery has two copper rings as electrode; Sleeve 3 is installed near inside magnet case, spacing for bearing; Bearing 4 coordinates with splined shaft, sleeve to be installed; V-type friction plate 5 is connected by six uniform screws and magnet case 1; The semicircular upper spring seat 7 of two panels is connected on bevel gear 1 by screw; Spring 8 is placed on upper spring seat 7, and two semicircular lower spring cups 9 are engaged in outside upper spring seat 7, for limit spring 8; The armature 6 of band V-type friction plate is connected with screw and two semicircle lower spring cups 9 and installs, guarantee the armature 6 of upper spring seat 7, lower spring cup 9, spring 8 and band V-type friction plate integrally, now be with the keyway of the armature 6 of V-type friction plate and the spline fitted on bevel gear 1, guarantee slip in drive bevel gear 10; Again by assemble drive bevel gear 10, spring seat and spring, band V-type friction plate armature 6 integral installation on bearing 4, matching relationship is as shown in Figure 3.In actual use, driven wheel of differential 11 matches with drive bevel gear 10, plays function spacing mutually, respective axle system can be driven mutually to rotate simultaneously.
This clutch work has two kinds of operating modes:
1, under powering-off state: non-electromagnetic-force during power-off, now magnet case 1 and the non-adhesive of armature 6 of band V-type friction plate, due to the pretensioned spring power effect in spring seat, make V-type friction plate separate with the V-type friction plate of band armature, do not come in contact.Moment of torsion now from splined shaft 2 drives magnet case 1 to rotate by spline, but install because drive bevel gear 10 and splined shaft 2 are coordinated by bearing 4, therefore the bevel gear 1 on bearing 4 outer ring does not have the driving torque rotated, cannot the loaded driven wheel of differential 11 of rotating band and driven shaft 12.
2, in energising situation: during energising, magnet case 1 produces larger electromagnetic force, overcome precompressed spring force, the armature 6 of the band V-type friction plate making lower spring cup and be connected with lower spring cup moves down along the axis of bevel gear 1, thus make magnet case 1 and armature 6 adhesive of being with V-type friction plate, V-type friction plate is combined closely with the V-type friction plate 6 of band armature, and provides larger positive pressure on friction plate surface of contact.Time splined shaft 2 rotates, because mating face is V-type face, and friction factor is larger, frictional force on V-type surface of contact is very large, magnet case 1 will drive the rotation of the armature fitted with V-type friction plate, simultaneously because the armature 6 of band V-type friction plate is matched by spline and keyway with bevel gear 2, has driven the rotation of driven wheel of differential 11, and then transfer torque on driven shaft 12, realize exporting and commutation the moment of torsion on driven shaft 12.
In sum, these are only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
