With reference to Fig. 1.In the vertical centre top of wind-electricity energy storage electric vehicle propons (1) and back axle (2), in four wheels (3) inboard, fastening four horizontal axis wind-driven generators of forming by electrical generator (4) and speed increaser (5).With reference to Fig. 2.In four horizontal axis wind-driven generators (4) speed increasers (5) rotating shafts (6), all one of suit has the antifriction-bearing box (7) of dust boot, rotating shaft end (8) is made the prismatic axle with an end (9) of joint yoke, shell-like is coupled to each other, and pierce into trepanning (10) with screw and hold out against prismatic axle head (8), make two parts closely overlap (riveting, weldering) and connect.Universal joint flange fork (11) shape invariance, coupling method is seen below and is stated.With reference to Fig. 3.Other at four wheels (3), along the axletree vertical center line, two semicircle dust-proof plates (12) are together involutory, passed screw (13) by screw and are fixed on the axletree.In the rim flange (15) on four wheels (3) steel rings (14), make antifriction-bearing box (16), dust-proof plate (12) periphery engages with antifriction-bearing box (16) inner ring.Above the axletree vertical center line, the dust-proof plate apposition position is the equal-sized circular port of antifriction-bearing box (7) overall diameter (17) in a same electrical generator (4) speed increaser (5) rotating shaft (6).Other at wheel rim (18) inwall (19) dust-proof plate (12), be a double cone inner gear (20) that forms by two female cone gears system of closing.At this gear recess (21), with double cone inner gear (20), be installed on wheel rim (18) inwall (19) with interior side's screw.With reference to Fig. 4.With double cone inner gear (20) ingear, be to link and the double cone external gear (23) made by two back cones (22), four screws (25) in the centre of one side link up with screw with universal joint flange fork (11).The structure of this gear is divided into center shaft and gear teeth two parts, its rolling connection place (24) is identical with the bicycle freewheel principle of work, and when promptly vehicle advanced, whole gear rotated with wheel, and when vehicle backing, having only the gear teeth with wheel, the gear center shaft portion does not rotate.Wind-electricity energy storage electric vehicle horizontal axis wind-driven generator and other parts coupling methods are as mentioned above.When wind-electricity energy storage electric vehicle travels under battery power drives, the double cone inner gear (20) that is fixed on wheel (3) wheel rim (18) inwall (19) also rotates together, drive the double cone external gear and pitch (11), universal-joint fork (9) by joining universal joint flange, speed increaser rotating shaft (8), (6), driving aerogenerator speed increaser axle rotates, thereby make horizontal axis wind-driven generator (4) rotary electrification,, realize purpose of the present invention to storage battery input electric energy.

Wind-electricity energy storage electric vehicle can be made two kinds of FD-A type battery-driven car, FD-B type battery-driven cars.FD-A type battery-driven car is the interior upside that leans on wheel on every axletree, and two typhoon power generators are installed; FD-B type battery-driven car is except that front axle, and the interior upside by wheel on every axletree is installed two typhoon power generators.For reducing the loss of electric energy in the transmission of electricity process; the method (transmission of electricity in parallel) that the power transmission line series connection of each aerogenerator can be led to battery pack or take aerogenerator to generate electricity by way of merging two or more grid systems; and on power transmission line, connect the dynamo control generator regulator of forming by pressure governor, air restrictor and contact breaker respectively and (also can adopt improved aerogenerator to fill overdischarging protector and revolution speed control device; in order to the protection storage battery, make the electrical generator stable working).The effect of pressure governor is: after aerogenerator voltage reaches the full quota, voltage is no longer raise with rotating speed, avoid the too high bad accumulator electrode that fills of aerogenerator series voltage.The effect of air restrictor is: the electric current of automatic generator output, and make it be no more than the permission limit, the protection dynamo armature is not burnt out.The effect of contact breaker is: when the electrical generator series voltage reaches certain numerical value above battery tension, automatically the circuit between two power supplys is connected, guaranteed that electrical generator is to the consumer power supply and to battery charge; When generator voltage is lower than battery tension, automatically with the circuitry cuts between two power supplys, in case storage battery burns out armature coil to a large amount of back discharges of electrical generator.Aerogenerator speed increaser rotating shaft cover connects or makes gear, and the gear interior through transmission gear and rear driving axle axle housing is meshed, and utilizes its unnecessary power to make wind turbine power generation.With in like manner above-mentioned, front axle is made the rear driving axle style.But because front-wheel has the function that turns to, so, it is two joints that semiaxis is broken at the front-wheel steering place, link up by universal-joint, make it when vehicle is kept straight on or turned, can both be the rotary power of wheel, be delivered to the other end (must note at this: the wheel steering angle is identical with the angle of universal-joint) by an end of semiaxis, make the rotating shaft of aerogenerator speed increaser obtain the power that the semiaxis transmission comes, drive the aerogenerator rotary electrification by a gear case.Aerogenerator not only can connect generating with wheel on self-propelled vehicle, also can same train, the wheel of all power actuated vehicles such as subway train, trac. connects, make its power-generation energy-storage, also can be applicable on the aircraft, change aloft air resistance into the power delivery accumulators.With clutch equipment control aerogenerator and wheel clutch, so that battery-driven car is in starting, quicken to wait when needing macro-energy, make two isolation of components, when travelling than pulsation-free speed, two parts mesh again, if but select efficient low wind speed wind power generator for use, then can not need clutch equipment (as the aerogenerator of selecting for use 2.5 meter per second gentle breezes to generate electricity, power required when generating electricity because of it is very little, can not increase the loss of energy so add it, not influence the normal speed of a motor vehicle and power yet, tie up on the automobile with rope as same ordinary people and pull at, automobile but at all need not be required great effort, and also just can pull away the people the same without open the throttle wide).In application, can adopt horizontal axis wind-driven generator, also can adopt vertical shaft type wind-driven generator, both functions are identical, only the coupling method difference.Battery-driven car is not if adopt four-wheel steering, and then the aerogenerator speed increaser rotating shaft on the back axle just can directly connect with the double cone external gear that two back cones link.As the aerogenerator speed increaser rotating shaft socket on the back axle or make gear, the wheel rim inwall is also made gear, makes two parts gear coupling transferring power.The double cone external gear that two back cones link can be made the pattern as bicycle freewheel, is meshed with corresponding perforation on the wheel.If the double cone inner gear is not made an integral body, then help the loading and unloading maintenance more but make two semi-circular portions.The width of the rolling bearing inner ring in the rim for automobile wheel flange should be slightly less than the outer ring, rubs in order to avoid produce with miscellaneous part when rotating.The rolling bearing inner ring inwall is made channel form, and the dust-proof plate edge is entered in the groove, can increase dust-obstructing efficiency; The dust-proof plate edge also can put rubber coating, with the leak tightness of increase with rolling bearing inner ring.The aerogenerator shell can be made can supporting power, above steel spring and bumper are placed, also can move other places in addition.The inside and outside gear of double cone can select for use rigid plastic to make.Aerogenerator can be selected according to the factors such as voltage request of power, weight and the battery pack of vehicle.Can select the low speed of a motor vehicle, middling speed for use and the aerogenerator of several different capacities that generate electricity at a high speed, like this, the storage battery above battery-driven car and the train etc. just not only when middle and high speed, and, when the low speed of a motor vehicle, can access the electric energy of aerogenerator output equally.As: about 630 millimeters of car Santana wheel overall diameter, wheel circumference is about 1.978 meters.If the speed of a motor vehicle is when being 10 kilometers/hour, it is ten thousand metres/3600 second that vehicle moves speed per hour, is roughly equal to 2.777 meter per seconds.This wheel revolutions one circle (wheel circumference) is 1.978 meters, removes 1.978 meters with 2.777 meter per seconds, and learn: wheel has changeed about 1.4 circle/seconds in the unit time.Again because, the overall diameter of the double cone external gear that links with aerogenerator speed increaser axle is less than radius of wheel, so, in double cone, the number of teeth of external gear, just can calculate the revolution of rotating shaft of aerogenerator speed increaser and electrical generator per second, again according to each stage stroke of battery-driven car (as 10 kilometers/hour, 20 kilometers/hour ...) in torsion when the torsion of wheel and various aerogenerator speed increaser axle work done, calculating does not influence battery-driven car allow additional torsion when cruising, thereby selects the aerogenerator of power demand according to different needs.
