Abstract
The present invention relates to a kind of double-driven electrically-aided bicycle with driven hubs, belong to the trackless terrestrial vehicle field in the communications and transportation.This electrically-aided bicycle can drive by front and rear wheel simultaneously, again can single wheel drive, the wheel hub of its front and back wheel is an engine installation, interior sabot shape direct current power machine and gear system, link by a purpose made flexi-fix ring face contact type overriding clutch and wheel hub, its effect is when adopting single wheel drive, avoids another drive system of taking turns to be formed resistance by drive.This vehicle is novel, and is simple in structure, and car body is light, energy-conservation, and driveability is good, easy to maintenance.
Description
The present invention relates to the two electrically-aided bicycles that drive of power hub-type, belong to the overall structure and the driver train field of bicycle.
Since 1970's, under the stimulation of energy shock and problem of environmental pollution, various countries begin to develop elec. vehicle, comprise electronlmobil and Electrical Bicycle.
The Electrical Bicycle that various countries developed, main pattern all are outer driving types, and promptly motor is installed in a certain position of vehicle frame, behind gear reduction, by chain or strap drive wheel.The type of drive that powered rear wheels also once occurred, promptly rear wheel hub is the discoid motor about a φ 260mm, the direct drive wheel.Its inner structure as shown in Figure 1.
The objective of the invention is to make the powered rear wheels that electric wheel replaces outer transmission with gear-driven electric wheel hub with a kind of.In order to reduce the wheel hub volume, expendable weight and improve drive performance has proposed the two type of drive that drive of front and back wheel, makes bicycle can freely select the driving of single-wheel or two-wheel with the difference of conditions such as road surface, wind direction.Adopt single-wheel (trailing wheel or front-wheel) to drive during level road, adopt two-wheel to drive when last ripple or contrary wind.Can replace mechanical speed change to play speedup, speed change or reinforcement, can make each machine operation again under best (most effective) state.For another drive system of taking turns when the single wheel drive is not driven, be provided with special-purpose face contact type overriding clutch in wheel hub inside.
Description of drawings:
Fig. 1 is a prior art.
Fig. 2 is an overall structure of the present invention.
Fig. 3 is a power wheel hub inner structure.
Fig. 4 is a power wheel hub in-to-in face contact overriding clutch.
Fig. 5 is the side diagrammatic sketch of overriding clutch.
Introduce particular content of the present invention in detail below in conjunction with accompanying drawing.
Shown in Figure 2 is the surface structure of this car.Dynamic wheel 1 and back dynamic wheel 2 before before and after vehicle frame, installing.Two-wheeled can start the purpose of freely selecting single, double wheel drive for use to reach respectively.
Fig. 3 is a power wheel hub cut-away view.Discoid motor 3 in the wheel hub, by gear 4,5,6, power wheel hub 8 drives wheel behind clutch gear 7 reductions of speed.Drive disk assembly such as electrical motor, gear is installed in the fixed mount 9.Fixed mount then is fixed on the vehicle frame front and rear fork by left and right half 10,11.15 is flywheels among the figure, the 16th, and bearing.
Fig. 4 with shown in Figure 5 be that faces in the clutch gear 7 contact the overriding clutch structure.When the bicycle use driven by power, drive of motor clutch gear 7 rotates counterclockwise, and this moment, shifting block 12 control flexi-fix ringes 13 were locked on center 14, drove center 14 and wheel hub 8 rotations.When the bicycle use manpower drives, motor stops operating, pedal and chain-driving drive wheel hub 8 rotates wheel forward, this moment, center was initiatively made left-hand revolution, shifting block 12 control flexi-fix ringes 13 get loose, flexi-fix ring 13 slides on center 14, and motor and gear train assembly and center 14 are thrown off fully, in order to avoid motor and gear dally and cause resistance.This overriding clutch is simple in structure, compact, noiseless, reliable operation, little, the superior performance of impact.
After double-driven electrically-aided bicycle with driven hubs of the present invention is manufactured experimently into sample car, when using single wheel drive, average 17 kilometers/hour of the speed of a motor vehicle; When driving with two-wheel, average 20 kilometers/hour of the speed of a motor vehicle; Go up a slope and against the wind the time, adopt two-wheel to drive, still can keep 17 kilometers/hour the speed of a motor vehicle.Used motor is a NdFeB rear-earth magnet steel discoid motor, 24V, 100W.
According to the result on trial analysis, this kind vehicle has following advantages than general outer transmission single wheel drive formula electric motor car:
1. electric speed reducer is simple in structure, and is in light weight, and two cover wheel hub gross weights are less than 4kG, and general motor reducer weight is not less than 6kG.
2. single, double motor switches, and speed change, reinforcement function are arranged, and exempts to use mechanical variable speed device, when driving with two-wheel, has climbing and the good characteristics of contrary wind performance.
3. efficient, power saving, single, double motor all operates near the rating horsepower, and electrical efficiency is the highest.General single motor-driven is because through the 1/2 rating horsepower place operation of being everlasting, electrical efficiency very low (being about about 50%).
4. power wheel hub good integrity is a modular organization, is convenient to the dismounting maintenance, and the waterproof anti-fouling is good.
5. dynamic wheel also can be used to assemble the vehicle of various uses such as three-wheel vehicle, four-wheeled as general module.
Claims (3)
1, a kind ofly take turns molecular electrically-aided bicycle by handlebar, vehicle seat, vehicle frame, pedal, blockchain and former and later two, two-wheeled is dynamic wheel before and after it is characterized in that, two-wheeled is that the energy can start respectively with the storage battery.
2, a kind of bicycle as claimed in claim 1, it is characterized in that described dynamic wheel wheel hub inside contacts overriding clutch, fixed mount and left and right half by motor, gear, clutch gear, face and forms, drive disk assembly such as electrical motor, gear is installed in the fixed mount, and fixed mount is fixed on the vehicle frame front and rear fork by left and right half.
3, a kind of bicycle as claimed in claim 2 is characterized in that described contact overriding clutch is installed in the clutch gear, and power-transfer clutch is made up of shifting block, flexi-fix ring, center.
