Description
Technical field
The present invention relates to the foot drive device of bicycle, Electrical Bicycle, particularly bicycle, front wheel of electric bicycle foot drive device.
Technical background
?the foot drive device of bicycle, Electrical Bicycle is all located between axis and rear axle both at home and abroad, does not also have at present a kind of foot drive device to be located on front axle, although there are many f-w-d schemes, perfect mostly not.For example Chinese patent CN200520111343 bicycle front-wheel drive device, is the tortuous handle of mounting wheel on handlebar, and with arm driving, this design is representative, can be used as health and fitness facilities and vehicle for disabled person.Other relates to meter, as CN201220587423 bicycle front-wheel drive device, on handlebar, to connect fork shaped lever, both sides are equipped with change-speed box, but also in combination on front fork set up a large amount of parts, make the numerous and jumbled cost of structure excessive, main is, most designs are all wheel disc chains, also there is no a kind of design plan that uses front axle itself to do axle drive shaft.
Summary of the invention
object of the present invention, to provide exactly a kind of Manpower driver being arranged on bicycle, Electrical Bicycle front axle: front-wheel main shaft Direct Driving System, this drive system has been abandoned traditional gear wheel chain drive, becoming rotating drive shaft direct drive of wheel with the peaceful dead front axle that supports front-wheel of bolt, compact conformation, volume is small and exquisite, transmitting ratio is large, mechanical efficiency is high.
For realizing above-mentioned technical goal, the technical solution used in the present invention is: front-wheel main shaft Direct Driving System has gear-type overrunning clutch, gear accelerator, drives several parts of gear disc crank, drive shaft and bearing to form, wherein, gear-type overrunning clutch is arranged on the flywheel interface of wheel nave, drive shaft, through after wheel hub centre hole, is used wheel bearing location in the hub spindle bowl of the left and right sides; By the drive shaft that wheel has been installed, through left and right back vent mouth, assembling fork bearing location in fork mouth pedestal, finally installs in outer end, both sides and drives gear disc crank and pedal.Described gear-type overrunning clutch is arranged on the flywheel interface of front vehicle wheel right side, or be arranged on the flywheel interface of front vehicle wheel left side, in the time that gear-type overrunning clutch is arranged on the flywheel interface of front-wheel right side, front-wheel main shaft Direct Driving System is just arranged on right fork leg one side, in the time that gear-type overrunning clutch is arranged on the flywheel interface of front-wheel left side, front-wheel main shaft Direct Driving System is just arranged on left fork leg one side.The major part of described gear-type overrunning clutch is that ratchet lock tube and few tooth fly head, and wherein ratchet lock tube is articulated on flywheel interface, and few tooth flies head and is provided with gear with little teeth number.Described ratchet lock tube is a cylindrical shape adaptor, its one end is provided with general screw socket, can be hinged with on the flywheel interface of any bicycle and Electrical Bicycle, the inside of ratchet lock tube be provided with bicycle freewheel general surmount hook tooth, the other end of ratchet lock tube is provided with axle bowl.The afterbody that described few tooth flies head has symmetrical very heavy groove and interior axle bowl, and the other end that flies head at few tooth is provided with gear with little teeth number, is provided with balance shaft bowl in addition in the inside of gear with little teeth number.In the left fork leg of described front fork or right fork leg, be welded with in one logical, in logical be a pipe, there is lattice gear in its cylinder center, both sides are provided with symmetrical bearing groove.In penetrate acceleration axle in logical, and in the bearing groove of the left and right sides, use and accelerate bearing location, then in the outside of fork leg, miniature gears is installed, in the inner side of fork leg, big gear wheel is installed, miniature gears, big gear wheel, acceleration axle are combined into in-line gears accelerator; Require miniature gears and drive fluted disc good engagement, big gear wheel and gear with little teeth number good engagement.Gear accelerator and driving fluted disc, gear with little teeth number form Multi-stage transmission, cooperation through different moduluses, the different numbers of teeth obtains high transmission ratio, embodiment mono-: establish and drive the modulus m=1.5 of fluted disc to get 56 teeth, identical 20 teeth of getting of gear accelerator miniature gears modulus, the big gear wheel modulus m=1.5 that gear accelerator is coaxial, get 56 teeth, identical 20 teeth of getting of gear with little teeth number modulus, transmitting ratio is up to 7.8; Because axle drive shaft is again the axletree of support flying wheel, therefore drive the width between centers h1 of fluted disc and miniature gears, equate with the width between centers h2 of big gear wheel and gear with little teeth number, i.e. h1=h2, h more big speed ratio is larger, embodiment bis-: establish and drive the modulus m=1.5 of fluted disc to get 64 teeth, identical 20 teeth of getting of gear accelerator miniature gears modulus, the big gear wheel modulus m=1.5 that gear accelerator is coaxial, gets 64 teeth, identical 20 teeth of getting of gear with little teeth number modulus, transmitting ratio is up to 10.2.
First the present invention discloses gear-type overrunning clutch, and combination gear accelerator cleverly, now support wheel and flywheel, with the peaceful dead front axle of bolt, become rotary drive shaft that drives task, directly manpower pedal drives wheel, accessory size is small, volume is small and exquisite, weight alleviates greatly, but because the precision of gear-bearing is high, driving efficiency obviously increases, thereby more energy-conservation, particularly even flying straight drive system can dwindle vehicle frame yardstick to gear, more unfold but ride, more humane, can be used for all bicycles, Electrical Bicycle, the DEVELOPMENT PROSPECT that tool is wide, thereby, positive effect of the present invention is very obvious.
