Fig. 6 show induction coil of the present invention lead-in wire schematic diagram.Induction coil 15 is made up of two groups of absolute coils, is wound in respectively in support bar bobbin winder bracket 1 winding slot.Support bar bobbin winder bracket 1 is provided with 9 winding slots, one of which absolute coil respectively from winding slot 2., 4., 6. and 8. by series connection mode be wound around, two lead-in wire A1And A2Entered the wire lead slot 102 of support bar bobbin winder bracket 1 bottom by the wire lead slot 101 of support bar bobbin winder bracket 1, then draw antivibrator from the fairlead 103 of support bar bobbin winder bracket 1；Another set absolute coil respectively from winding slot 1., 3., 5., 7. and 9. by series connection mode be wound around, two lead-in wire B1And B2Entered the wire lead slot 102 of support bar bobbin winder bracket 1 bottom by the wire lead slot 101 of support bar bobbin winder bracket 1, then draw from the fairlead 103 of support bar bobbin winder bracket 1.
Fig. 7 show magnet exciting coil of the present invention lead-in wire schematic diagram.Two lead-in wire C of magnet exciting coil 81And C2Entered the fairlead 202 of piston rod 14 by the wire lead slot 201 of piston 9, then drawn from the fairlead 203 of upper end cover 19 by the wire lead slot of piston rod 14.
Operation principle of the present invention is as follows:
When there is external drive, piston rod 14 in axial direction does reciprocating linear motion, and drives internal layer group of magnets to do reciprocating linear motion together with outer layer group of magnets.Under double-deck Magnet effect, the induction coil 15 being wrapped in support bar bobbin winder bracket 1 will produce alternating current in reciprocating motion, by rectification circuit, the alternating current of generation is converted into unidirectional current, thus can be directly used for the direct current supply of the magnet exciting coil 8 in piston 9 winding slot.By powering to magnet exciting coil 8, produce magnetic field, change the magnetic flow liquid yield strength in the damping clearance formed between piston 9 and antivibrator cylinder body 25, produce controllable damping force, thus complete vibrating machine energy and recycle.
If magnet exciting coil 8 is directly powered by external power source, gather the unidirectional current changing and also can be stored in accumulator.
