Abstract

A magnetic controlled loading device in combination of a power generating set and an adjusting drive mechanism having a flywheel, a shaft, a transmission element, a magnetic controlled loading device, a micro power generating set and an adjusting drive mechanism integrated into one single unit. It can also be taken apart and used in various combinations. By fully utilizing the limited space without increasing the volume of the flywheel and internal components, a rotor and a stator are disposed in the center of the magnetic controlled loading device. This makes the rotor'"'"'s permanent magnets to be set on top of the flywheel'"'"'s inner ring, so that when the flywheel is in operation, it turns into a micro power generating set. By utilizing its self generating power supply, it can provide the power needed by a small motor and by manual adjustments it can also control the changes in magnetic flux density between the flywheel and device as well to achieve continuous adjustment of loading resistance.

Claims

1. A magnetic controlled loading device in combination with a power generating set and an adjusting drive mechanism, comprising:

a) a flywheel having a first and a second bearing disposed within a hub of the flywheel, the flywheel being recessed under a wheel rim, which forms a receptacle, a metal conductor being mounted on the inner surface of the wheel rim;

b) a shaft passing through the flywheel and having both threaded ends;

c) a transmission element positioned at the external side of the flywheel and adapted to bring the flywheel in rotation;

d) a micro power generating set having a plurality of permanent magnets mounted on the inner surface of the hub and a stator core placed on the shaft, the permanent magnets acting relative to the stator core acting as a rotor; and

e) a magnetic controlled loading device including;

i) an outer cover having a groove opposing to the micro power generating set in the center of the shaft hole;

ii) an adjustable stator having a pair of opposite facing circular magnetic plates, the magnetic plates each having a plurality of permanent magnets positioned on the outer side thereof and a plurality of compression springs fitted to the inner side thereof, the magnetic plates each further having a first end swiveled on a pivot and a second movable free end, the pivots of the magnetic plates being diagonally positioned on the outer cover, a pull rope being joined to the free end;

iii) an adjustment disc having

1) a rotation hole for insertion of the outer rim of the groove,

2) two positioning grooves facing to the corresponding pull rope at the free ends of the magnetic plates and formed at the top and the bottom end of the adjustment disc, and

3) an arched row of teeth positioned at the circumference thereof;

iv) an inner cover adapted to match the outer cover, the inner cover having in the middle thereof a positioning hole corresponding to the groove, the inner cover being joined to the outer cover with a plurality of screws so that the adjustable stator and the adjustment disc are located between the two covers, the inner cover further having an annular slot corresponding to the arched row of teeth; and

v) an electric adjusting driving mechanism having an electric and a manual mode for bringing the adjustment disc in rotation.

2. The magnetic controlled loading device as recited in claim 1 wherein the electric adjusting driving mechanism includes a micro motor, a reduction gearbox, and a driving pinion protruding from the bottom side of the reduction gearbox, and wherein the electric adjusting driving mechanism is fastened to the surface of the inner cover by screws, and wherein the driving pinion further passing through the annular slot of the inner cover to mesh with the arched row of teeth.

3. The magnetic controlled loading device as recited in claim 1 wherein the adjusting driving mechanism is constructed in manual mode and includes a protruding member on the surface of the adjustment disc, and wherein the protruding member projects in axial direction into the circular slot of the inner cover, and wherein a control cable for controlling the swiveling action of the adjustment disc is jointed to the protruding member.

4. The magnetic controlled loading device as recited in claim 1 wherein the micro power generating set further comprises a power line through which the voltage produced by the stator core is transmitted to an AC/DC converter and then the direct current is supplied to the micro motor of the electric adjusting driving mechanism.

5. The magnetic controlled loading device as recited in claim 1 wherein the permanent magnets are fixed on an inner rim of the ring protruding from the hub, and wherein the stator core further includes a base that is positioned within a recess of the outer cover.

6. The magnetic controlled loading device as recited in claim 1 wherein a third bearing is interposed between the transmission element and the shaft while a single direction bearing is installed in the shaft hole to rotate the flywheel in a forward direction.
