Abstract
Automobile and engineering machinery magnetic variation speed clutch, it is that traditional engine flywheel is made into barrel-shaped shape, and load has the alternate electromagnetic pole rotor of south poles wherein with excitatory wire winding.When passing to DC current into excitatory wire winding, when engine rotates with barrel-shaped flywheel, due to the effect of electromagnetic force, electromagnetic rotor is by barrel-shaped flywheel with rotating together.The speed of the rotating speed of electromagnetic rotor, depending on the size of electric current in field winding in electromagnetic rotor, the big rotating speed of electric current is then fast, and the small rotating speed of electric current is then slow.It can be replaced mechanical speed changer in line with this characteristic.If the electric current in field winding is zero, there is no electromagnetic connection between the barrel-shaped flywheel and electromagnetic rotor of engine band, do not involve similar in appearance to mechanical clutch mutually and be in released state, this characteristic just substitutes the centrifugation of clutch.The electromagnetism speed change clutch manufactured by this principle, has the advantages that simple in construction, small volume, safeguards that easy, service life is long.
Description
The present invention relates to delivery equipment and utensil
With the fast development that science and technology is with rapid changepl. never-ending changes and improvements, the present of earth-shaking change all occurs for every field items technology
My god, constantly struggle is also enjoying the good life that is brought by struggle to people simultaneously.Just exist by automobile conventional exemplified by automobile
Next stage gear is changed in driving by higher leveled gear because the gear of the carrying separation and combination of gearbox at that time does not have
Current synchronizer, pin space oil must be added by being stopped the one of clutch separation, and its purpose is to will be combining two gear
Peripheral speed be adjusted to unanimously, this is motionless to be equal to geo-stationary between two gears, thus can be readily ratcheting.Due to science
Fast-developing technology is constantly updated, and has synchronizer in the speed changer of modern automobile, this reduces very big fiber crops to driving
Must, otherwise Special Training not to driver in this respect, then it is difficult manipulation automobile that driver, which is,.Although present is automatic
The automobile of shelves provides the convenience driven to human pilot very well, is loved by people, and drives and becomes to enjoy completely... it is
Make be so, inventor I think that the speed changer of automobile and clutch are still significantly improved space.Present automobile (engineering
Equipment) generally all also with the mechanical clutch with friction plate.The clutch has the disadvantage that, 1 it is complicated and add
Work, manufacture, maintenance, using being all not easy.2nd, heat is easily produced, special oversize vehicle is at a relatively high in hot its temperature of summer,
The abrasion that temperature height exacerbates machinery increases oil consumption.3rd, short life, clutch disc belong to consumable accessory and need to often changed, flywheel, dial
Fork, pressing plate ... wait annex also to need often dimension to repair more Change, and changeing once wastes time and energy, and Lao Min funeral wealth is inconvenient.Speed changer is also same
Sample, complicated processing and manufacturing also is difficult to, besides also with there is above-mentioned common fault clutch.There is provided herein for this inventor
Single between a kind of structure, processing and manufacturing is all easier, and easy to maintenance, manipulation is easy, the electromagnetism speed change and the dress of clutch of long lifespan
Put and substitute current clutch and speed changer.To reach this purpose, the present invention is with soft by the flywheel of engine crankshaft end
Barrel-shaped flywheel is made in magnet (wrought iron or the small silicon steel sheet of the high magnetic hystersis loss of magnetic conductivity or Bo Liniya alloys) material, joins with bent axle
Body can rotate together.Then by one be wound with field winding and external diameter be slightly smaller than barrel-shaped flywheel internal diameter electromagnetic rotor put into it is barrel-shaped
In flywheel.If passing to DC current in the field winding of the electromagnetic rotor during bent axle rotation, the electromagnetic rotor will be with
Barrel-shaped flywheel on bent axle is rotated together.If changing the current strength in electromagnetic rotor in field winding, electromagnetic rotor will be with
Different rotating speed rotations.Electric current is almost consistent with engine crankshaft with no-load speed to electromagnetic rotor during setting value.The small electricity of electric current
The rotating speed of magnet rotor reduces and reduced with electric current.The big then speed of electric current is then big.Theoretically the rotating speed of electromagnetic rotor can from zero to
The rated speed of engine.Not having current flowing in field winding in electromagnetic rotor, then electromagnetic rotor does not have any melon to cut with bent axle,
Mutually do not involve this equally has the clutch of friction clutch chip that the power cut of engine is the same completely.Its speed governing model Wai
Greatly, speed governing curve levels off to continual garden and slides curve, better than the staircase curve of the speed changer with gear stepping formula.Speed regulation process
In unlike having the speed changer of gear in shifted middle generation impulsive force, speed governing garden, which is slided, operates steadily, in engine and hauling machine
Between serve buffering effect reduce mechanical shock and reduce mechanical wear be all good.Scheme system proposed by the present invention
The electromagnetic speed-adjusting clutch made due to it is simple in construction it is easily fabricated, operate steadily, without frictional dissipation, do not have rapid wear friction member,
Many advantages, such as manipulating easy easy, maintenance, small in volume, long lifespan ..., should be automobile, engineering truck, ship ... etc.
Deliver a technological innovation and technological revolution for clutch and speed changer in equipment.
