Abstract
The utility model relates to an auxiliary drive vehicle with a central motor, which adopts the structure that manpower and electric power drive units are independently divided by a composite flywheel. The prior flywheels on the back wheels of a two-wheeled bicycle and a tricycle are eliminated and changed into fixed back wheel discs; a direct current motor is laterally arranged at the lower part of a frame between a front foot-pedal wheel disc and each back wheel; the composite flywheel is mounted on the transmission shaft of the direct current motor and comprises an inner flywheel and an outer flywheel; the outer flywheel is connected with the front foot-pedal wheel disc through a front chain group; the inner flywheel is combined with the transmission shaft of the direct current motor and connected with the back wheel discs through a rear chain group; and the inner flywheel is combined with the outer flywheel through a flywheel shaft sleeve. The utility model keeps the portable characteristic of a man-powered vehicle to the utmost limit and has a simple structure.
Description
Technical field
The utility model is a kind of two-wheeled cycle and three-wheel vehicle with DC machine assistive drive trailing wheel.
Background technology
At present, electronic two-wheeled cycle great majority adopt rear wheel hub motors to drive on the electronic market, three-wheel vehicle or drive the back side wheel with wheel hub motor, otherwise additional one apply mechanically flywheel, chain, the wheeling disk structure that inner rotor motor drives, and latter event more is common in the electro-tricycle of repacking.In electromechanical structure design, the basic mode of machine operation is to pass out power by gear, sprocket wheel, belt pulley, seldom has to work under the load of being directly exposed to; So the work under bad environment of wheel hub motor requires high to structural strength.Therefore, the wheel hub motor productive costs is higher, and the direct bearing load of motor impacts in the trailing wheel rolling process, and it is unfavorable that service life and maintenance are caused; In the process of riding, when motor was not worked, the passive rotation of motor increased resistance, makes ride ' portability ' very poor.
Summary of the invention
The utility model has overcome the shortcoming that rear wheel hub motors drives, and can adopt internal rotor DC machine assistive drive back wheels of vehicle, utilizes the compound flywheel technology to have realized that manpower and two driver elements of electric power can be separate, mode that again can collaborative work.
The structure that the mid-motor assistive drive of the utility model car adopts compound flywheel that manpower and two driver elements of electric power are independently cut apart.The technical scheme that its technical matters that solves the utility model adopts is: adopted by direct supply, and DC machine, the electromechanical structure that control circuit is formed drives two-wheeled cycle and three-wheel vehicle as auxiliary power; Change the flywheel on the trailing wheel into fixing rear trochal disc; The horizontal direct current motor in vehicle frame bottom between preceding pedal wheel disk and trailing wheel is installed a compound flywheel on the transmission shaft of DC machine; Compound flywheel is made up of interior flywheel and outer flywheel, interior flywheel overlaps by flywheel shaft with outer flywheel and combines, flywheel and rear trochal disc in the link of one group of chain, one group of outer flywheel of chain link and preceding pedal wheel disk, realize motor and manpower get final product independently again can collaborative work type of drive.
The beneficial effects of the utility model are, have kept the light characteristic of rickshaw to greatest extent, and are simple in structure.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
The structure that the mid-motor assistive drive of the utility model car adopts compound flywheel that manpower and two driver elements of electric power are independently cut apart.In embodiment illustrated in fig. 2, the utility model has adopted by direct supply, DC machine 1, and the electromechanical structure that control circuit is formed is as the driving car of auxiliary power.Flywheel in the structure on cancellation two-wheeled cycle and the three-wheel vehicle hind axle is used with preceding pedal wheel disk 2 similar rear trochal discs 7 to replace on its position, and is done big rear trochal disc 7 diameters as far as possible to strengthen the arm of force; The horizontal direct current motor 1 in vehicle frame bottom between preceding pedal wheel disk 2 and trailing wheel, compound flywheel is installed on the transmission shaft of DC machine 1, compound flywheel is made up of outer flywheel 4 and interior flywheel 5: the structure of outer flywheel 4 and the back flying wheel of cancellation and to screw direction identical, belong to the clockwise direction flywheel, and link by preceding chain group 3 and preceding pedal wheel disk 2; Interior flywheel 5 is identical with the trailing wheel flywheel structure of cancellation, but it is opposite to screw direction, belongs to conter clockwise to flywheel, and links by rear chain group 6 and rear trochal disc 7; The inner ring of interior flywheel 5 combines with the transmission shaft of DC machine 1, and interior flywheel 5 combines by flywheel axle sleeve 8 with outer flywheel 4, and flywheel axle sleeve 8 combines with the outer ring of interior flywheel 5, combines with the inner ring that flies 4 outward.Battery compartment 9 is used to lay lead-acid batteries.
When only depending on manpower to ride forward, preceding pedal wheel disk 2 drives outer flywheel 4, the outer ring of flywheel 5 in outer flywheel 4 drives, and the outer ring of interior flywheel 5 drives rear trochal disc 7, makes clickwise simultaneously, and car is to moving ahead; Because interior flywheel 5 is reverse flywheels, so the transmission shaft of its inner ring and DC machine 1 is can passive rotation.When only depending on DC machine 1 work, the transmission shaft clickwise of DC machine 1, because interior flywheel 5 is reverse flywheels, so the Internal and external cycle of flywheel 5 in driving, interior flywheel 5 drives rear trochal disc 7, makes clickwise simultaneously, car is to moving ahead; Because outer flywheel 4 is flywheels forward, the outer ring and the preceding pedal wheel disk 2 of flywheel 4 are can passive rotation in addition.When manpower and motor drive simultaneously, can draw by the fwd analysis, the boot sequence of two kinds of drivings can replace arbitrarily, and can not cause that machinery disturbs because of the difference that drives rotary speed.Be the love motor, preferably start simultaneously by manpower or backward manpower and motor earlier that relying on motor-driven more fully when waiting to reach certain speed of a motor vehicle is the most desirable mode of riding.
When reversing back, flywheel 5 left-hand revolutions in rear trochal disc 7 drives are because interior flywheel 5 is reverse flywheels, so drive the transmission shaft left-hand revolution of DC machine 1.If DC machine 1 is slow speed of revolution and the motor that does not have speed reduction gearing, above-mentioned situation allows; If DC machine 1 is a pot motor, by speed reduction gearing, the form output torque of turbine and worm speed reduction gearing especially, above-mentioned situation is unallowed.
