Abstract
The utility model discloses a hand drive fast bike, which comprises a front wheel fork arranged on the front end of a vehicle frame, wherein the front wheel fork is provided with a drive device consisting of a chain wheel and a gear, while a vehicle handle and a rotary handle are arranged on the upper end of the front wheel fork; and the rotary handle is provided with a drive chain wheel, while a small flywheel is arranged below the front wheel fork. When driving the bike, the drive chain wheel on the rotary handle is used for driving the drive wheel on the front wheel fork to drive the small flywheel on the front wheel shaft to move forward; and two middle shafts which are arranged one after another and a drive chain wheel are arranged on the bottom end of the bracket, thus increasing the drive torque force and improving the speed.
Description
The utility model relates to a kind of walking-replacing tool, definite a kind of quick bicycle that front and back drive that has of saying so.
The various bicycles of Xiao Shouing adopt the foot-operated trailing wheel walking that drives usually in the market, and are often comparatively painstaking when vehicle heavy duty or climbing, even the implementation of getting off, and not only require great effort but also mistake.
The purpose of this utility model provides and a kind ofly can strengthen power, and that improves speed has the quick bicycle of hand-drive in conjunction with the arc pedal rod.
Scheme of the present utility model is by vehicle frame, handlebar, turning handle, front-fork, drive sprocket, driven sprocket, big miniature gears, the front and back axis, small flywheel and arc pedal rod are formed, its constructional feature is that the front end at vehicle frame is equipped with front-fork, the upside of front-fork is equipped with handlebar, turning handle is equipped with in the front side of handlebar, the both sides of turning handle are provided with anti-skidding, drive sprocket is equipped with at the middle part of turning handle, three groups of transmission shafts are housed on the front-fork of drive sprocket downside successively, big gear wheel and minor sprocket are housed on first transmission shaft, hinge wheel and miniature gears are housed on second transmission shaft, two sprocket wheels of size are housed on the 3rd transmission shaft, front wheel spindle is equipped with in the lower end of front-fork, and front-wheel and small flywheel are housed on the front wheel spindle.Preceding axis is equipped with in the bottom of vehicle frame, and the rear side of preceding axis is equipped with the back axis, and hind axle is equipped with in the rear end of vehicle frame, and arc pedal and hinge wheel are housed on the preceding axis, and large and small two sprocket wheels are housed on the back axis, and trailing wheel and small flywheel are housed on the hind axle.
The utility model has the advantages that owing to increased hand driving device and improved foot-operated drive mechanism, thereby make vehicle increase driving torsion under steam, and improved speed.
Be described further below in conjunction with accompanying drawing:
Fig. 1 is the quick bicycle front elevation of hand-drive in conjunction with the arc pedal rod;
Fig. 2 is the quick bicycle lateral plan of hand-drive in conjunction with the arc pedal rod.
Front-fork 11 shown in Fig. 1 is installed in the front end of vehicle frame, handlebar 4 is equipped with in the upper end of front-fork, turning handle 2 is equipped with in the front side of handlebar, the both sides of turning handle are equipped with anti-skidding 3, drive sprocket 1 is equipped with at the middle part of turning handle, and first transmission shaft 6, second transmission shaft 8, the 3rd transmission shaft 10 are housed on the front-fork of drive sprocket downside.Big gear wheel 19, minor sprocket 5 are housed on first transmission shaft, on minor sprocket 5 and the drive sprocket 1 driving chain 20 are housed; Hinge wheel 18, miniature gears 7 are housed, miniature gears 7 and big gear wheel 19 engagements on second transmission shaft; Hinge wheel 16, minor sprocket 9 are housed on the 3rd transmission shaft, on minor sprocket 9 and the hinge wheel 18 driving chain 17 are housed.Front wheel spindle 12 is equipped with in the lower end of front-fork, and small flywheel 14, front-wheel 13 are housed on the front wheel spindle, on small flywheel 14 and the hinge wheel 16 driving chain 15 is housed.The transmitting ratio of drive sprocket 1 and minor sprocket 5, two miniature gearss 7, three minor sprockets 9, front wheel spindle small flywheel 14 was respectively 1: 2: 4: 8: 16, drive sprocket 1 was a click formula sprocket wheel with front axle small flywheel 14.
The bottom of the vehicle frame 25 shown in Fig. 2 is provided with preceding axis 23, back axis 30, hind axle 28 is equipped with in the rear end of vehicle frame, hinge wheel 24 before being equipped with on the preceding axis, the left and right sides of sprocket wheel is equipped with left arc pedal rod 21 respectively, right arc pedal rod 22, back hinge wheel 32 is housed on the back axis, minor sprocket 31, trailing wheel 29 is housed on the hind axle, small flywheel 27, on preceding hinge wheel 24 and the back minor sprocket 31 chain drive-belt 33 is housed, on back hinge wheel 32 and the small flywheel 27 driving chain 26 is housed, small flywheel 27 is a click formula sprocket wheel, and the outside of each power wheel of front-fork is provided with protective cover 34.
During use, can be in foot-operated travelling, rotate turning handle 2 repeatedly with hand, the drive sprocket 1 that is contained on the turning handle is made 1/4 circle crank motion repeatedly on turning handle, when the turning handle revolution moves once, drive sprocket drives a minor sprocket 5 by chain 20 and just rotates 1/2 circle, big gear wheel 19 on one drives two miniature gearss 7 simultaneously and rotates 1 circle, the minor sprocket 9 that hinge wheel 18 on two drives on three simultaneously rotates 2 circles, and the hinge wheel 16 on three drives small flywheel 14 simultaneously and rotates 4 circles and drive front-wheels.Two arc pedals drive two groups of chain wheel drive and travel, and under the transmission speed ratio effect of assembly pulley principle and big minor sprocket, the utility model has not only improved speed but also reduced resistance to motion.
