Embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
As shown in figure 1 and 2, the invention provides a kind of high pulling torque electromagnetic clutch, the electromagnetic clutch to include magnetic conduction
Body 1, splined shaft 2, sleeve 3, bearing 4, V-type friction plate 5, the armature 6 with V-type friction plate, upper spring seat 7, spring 8, lower spring
Seat 9 and drive bevel gear 10, ancillary equipment are driven wheel of differential 11 and driven shaft 12；
The endoporus of magnetic conductor 1 of electromagnetic clutch has spline to coordinate installation with splined shaft 2, and magnetic conductor 1 has two on periphery
Copper ring is as electrode；Sleeve 3 is installed on the inside of magnetic conductor, 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 magnetic conductor 1；The semicircular upper spring seat 7 of two panels is connected in by screw
On bevel gear 1；Spring 8 is placed on upper spring seat 7, and two semicircular lower spring cups 9 coordinate outside upper spring seat 7, are used for
Limit spring 8；Armature 6 with V-type friction plate is connected and installed with screw and two semicircle lower spring cups 9, it is ensured that upper spring
Seat 7, lower spring cup 9, spring 8 and the armature 6 with V-type friction plate are used as an entirety, now the armature 6 with V-type friction plate
Keyway and bevel gear 1 on spline fitted, it is ensured that can be slided in drive bevel gear 10；The active conical tooth that will be assembled again
On wheel 10, spring base and spring, the integral installation of armature 6 with V-type friction plate to bearing 4, matching relationship is as shown in Figure 3.
In actual use, driven wheel of differential 11 is engaged with drive bevel gear 10, plays function spacing mutually, while can be mutual
Respective shafting is driven to rotate.
Clutch work has two kinds of operating modes：
1st, under powering-off state：Non-electromagnetic-force during power-off, now magnetic conductor 1 and the 6 non-adhesive of armature with V-type friction plate, by
In the pretensioned spring power effect in spring base so that V-type friction plate separates with the V-type friction plate with armature, is not in contact.
Moment of torsion now from splined shaft 2 drives magnetic conductor 1 to rotate by spline, but because drive bevel gear 10 and splined shaft 2 pass through
Bearing 4 coordinate installation, therefore the bevel gear 1 on the outer ring of bearing 4 without rotation driving torque, can not drive belt it is loaded from
Dynamic bevel gear 11 and driven shaft 12.
2nd, in the case of being powered：Larger electromagnetic force is produced during energization on magnetic conductor 1, precompressed spring force is overcome, under making
Spring base and the moving axially downwards along bevel gear 1 of armature 6 with V-type friction plate being connected with lower spring cup, so that leading
Magnet 1 and the adhesive of armature 6 with V-type friction plate, V-type friction plate is combined closely with the V-type friction plate 6 with armature, and is being rubbed
Larger normal pressure is provided on piece contact surface.When splined shaft 2 rotates, because composition surface is V-type face, and coefficient of friction compared with
Greatly, the frictional force on V-type contact surface is very big, the rotation for the armature that magnetic conductor 1 will drive and V-type friction plate fits, while by
It is engaged in the armature 6 with V-type friction plate with bevel gear 2 by spline and keyway, has driven the rotation of driven wheel of differential 11, entered
And transfer torque on driven shaft 12, realize to the torque output on driven shaft 12 and commutation.
In summary, presently preferred embodiments of the present invention is these are only, is not intended to limit the scope of the present invention.
Within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc., it should be included in the present invention's
Within protection domain.
