The utility model relates to motorcycle field, and it is to be a kind of motor-tricycle assembly apparatus of power supply with the direct current (DC).

At present, the motorcycle exhaust based on fuel oil in travelling is discharging dense black smoke, has brought aerial contamination for city and rural area, has become big public hazards of society.Preserve the ecological environment free of contamination electronlmobil, battery-operated motor cycle are introduced to the market, especially be subjected to the concern of society and customer's favor.

The purpose of this utility model is, provide a kind of electronic back axle assembly device to motor-tricycle, make the driving of motor-tricycle back axle assembly, power by the fuel engines generation, the drive back axle assembly drives, transfer to by the DC motor driving, thereby solved the problem of motor-tricycle exhaust emission.

Present design is such: it is arranged on DC motor between bonnet and the front frame, rotor shaft, commutator are installed on the rotor shaft and imput shaft, the same axis of driven shaft, on imput shaft and driven shaft, be with axle sleeve, fixing the back axle adapter plate on the axle sleeve, carrying the motor bike envelope on this adapter plate, power supply of dc motor is supplied with by the storage battery in the motor bike envelope, and wheel rotates immediately when motor rotates.

The advantage of this device is axle and motor integration, and structure is comparatively compact, and right alignment is comparatively accurately arranged, and adapts to and produces in enormous quantities, and environmental protection is played a positive role.

Referring now to above accompanying drawing, and in conjunction with the embodiments its feature is done following narration:

Electric motor tricycle back axle assembly device is electric motor tricycle carrying and the important component part that drives.This device is made up of brake mount 1, brake shoe expander 2, imput shaft 3, axle sleeve 4, back axle adapter plate 5, front end cover 6, bearing 7, coupler 9, output axle bed 12, output shaft 13, inner gear 14, bolt 15, casing 20, rotor 21, commutator 22, bonnet 24, rear side housing 26, driven shaft 29, permanent magnet 36, rotor shaft 37, front frame 39 etc., and wherein DC motor is made of casing 20, rotor 21, rotor shaft 37, permanent magnet 36, commutator 22, brush 35.Rotor shaft 37, rotor 21, permanent magnet 36 place casing 20, and casing 20 places between bonnet 24 and the front frame 39; Right-hand member at rotor shaft 37 is provided with commutator 22; Casing 20 is connected by bolt 15 with output axle bed 12.The direct supply of storage battery is introduced into casing 20 and makes motor rotation by commutator commutation effect, presses the running of cw or anticlockwise direction, must change power positive cathode and come adjusting control.Right-hand member at rotor shaft 37 is provided with commutator 22, is provided with a brushgear housing 33, and uniform four brush holders 34 near commutator, introduces power supplys by brush 35.Rear side housing 26, bonnet 24 are connected in casing 20 by four bolts 23, the brushgear housing of establishing in the bonnet 33 is the end faces that are fixed on bonnet by four screws 25, it is bearing 32 that bonnet links to each other with commutator 22 axles, what front frame 39 linked to each other with rotor shaft 37 is that 38, four screws 19 of bearing are fixed front frame 39 and casing 20.On front end cover 6, imput shaft 3, be with axle sleeve 4, on rear side housing 26, driven shaft 29, also be with axle sleeve 4, their two axial ends all is provided with brake mount 1, brake shoe expander 2, rotating shaft 31, hoof piece 44, and supported by bearing 7, bearing 30, its middle part is provided with back axle adapter plate 5, and the envelope of motor bike is fixed on this adapter plate exactly.Imput shaft 3 is fixing for bike wheel, assembly jack panel with the outermost end of driven shaft 29.In front end cover 6, be provided with coupler 9, it is captiveed joint with imput shaft 3 output shaft 13 by screw 3, be provided with an inner gear 14, three planetary wheels 17, three planet axis 43, three packing rings 41, three bearings 40, an output gear 42 between output axle bed 12 and the front frame 39, they are called speed reduction gearing.

The DC motor principle of work: the principle of work of DC machine is based upon on the electromagnetic coupling theory basis.Motor is made up of magnetic pole, armature, commutator and brush etc.; Armature is by multiturn coil coiled (not drawing view).Coil end is connected with commutator segment respectively, and each keeps moving contact with brush to commutator segment again, and every brush joins by lead-in wire and direct supply.

Behind power connection, just have electric current and flow into the armature conductor that is positioned at N polar region (or S polar region) through brush and commutator segment from positive source, flow out from the conductor that is positioned at S polar region (or N polar region) again,, make the electric motor starting running after another commutator segment and brush flow back to power cathode.

When armature conductor when a polar region forwards another polar region to, cooresponding commutator segment also forwards under another brush under a brush thereupon, thereby make the electric current in the armature conductor also be another direction from a direction transformation in time, this has just guaranteed that the suffered electromagnetic torque direction of armature conter clockwise (or cw) direction is constant, and electrical motor turns to constant.The effect of commutator is to guarantee when the conductor on the DC machine armature forwards to another magnetic pole under under the magnetic pole, and the direction of current in the conductor can corresponding change, thereby the electromagnetic torque direction of assurance armature is constant, and electrical motor turns to constant.

If with the power connection reversing of brush institute, then flowing through N polar region conductor will change with the direction of current that flows through S polar region conductor, the electromagnetic torque direction of armature and electrical motor turn to also and change thereupon, if brush and power supply connection are constant, and with the reversing of magnetic pole, the armature upper conductor is subjected to magnetic force direction and also can changes, and then electrical motor turns to change, clear and definite thus electrical motor turns to the change method to have two kinds, a kind of method is to change the polarity that is connected power supply with brush, and another kind of method is to change motor magnetic pole (being magnet) polarity.

The storage battery rated voltage is not more than 36V, the motor-tricycle that once charges about 70km that can travel continuously, and hundred kilometers power consumptions are not more than 3.5kmh.Therefore,, have the characteristics of power saving, energy-conservation, non-exhaust emission, be worthy of popularization by this device institute stack-mounted electric motor tricycle.
