Abstract
The utility model discloses a device for a handlebar driving a front wheel for a bicycle, which is mainly formed by that a transverse axis is fixed on the top of the vertical pipe of the bicycle; a bearing is arranged on the transverse axis to support a casing whose middle part is welded with a handlebar; the front end of the casing is welded or riveted with a driving disk; both sides of the flower drum of the front wheel are respectively provided with flywheels is sheathed with roller chains; one end of the roller chain is connected with a driving rope; the other end of the roller chain is connected with chain returning rope; the upper ends of the driving rope and the chain returning rope are respectively fixed at both sides of the driving disk. The utility model can realize that the bicycle is driven by hands to run forwards, can be trod by feet, or be driven by both the hands and the feet, and the utility model is an ideal tool for replacing walk and for body building.
Description
The utility model relates to a kind of bicycle handle bar and drives preceding wheel apparatus.
The normally used bicycle of people is proal with pin driving trailing wheel at present, yet there are no the bicycle of f-w-d on the market.It is a kind of on the basis of existing bicycle that task of the present utility model is to provide, and changes the device that drives the bicycle front-wheel with regard to available handlebar a little, for people can be manually when riding, foot-operated or trick and moving, reach good body-building effect.
Technical solution of the present utility model is: fix a transverse axis in the riser top ends of bicycle, this transverse axis is equipped with two cover bearing supporting shells, at shell middle part welding tractor handle, and welding of shell front end or riveted joint driving disk.Respectively adorn the flywheel that a number of teeth equates in bicycle front-wheel flower-drum both sides, right flywheel right-hand screw thread, left flywheel minus thread; Two roller chains are set on the flywheel of the left and right sides, and roller chain one end connects the driving rope, and the other end connects back chain cable, drive rope and go back to the chain cable upper end to be separately fixed at the driving disk both sides.
In the above-mentioned technical solution, on the bicycle front wheel guard, can fix a pulley, run into mudwing with twice chain cables about preventing.
In the above-mentioned technical solution, can on the standpipe below the handlebar, fix a killer, with the angle of control handlebar swing.
Because the utility model directly is welded on the shell middle part of transverse axis to handlebar, driving disk welding or be riveted on the front end of this shell, thereby, people can by on carry and press down handlebar, drive driving disk and rotate.When the right hand presses down when carrying handlebar on the left hand, driving disk rotates counterclockwise, and a left side drives that the moving subchain that rolls left of belt is rolled flywheel and front-wheel forward on the rope, and meanwhile the chain cable that returns on the left side descends synchronously.The right synchronous with it drives rope and moves down, move on the chain cable and return, otherwise, when left hand presses down when carrying handlebar on the right hand, then drive right flywheel and drive front-wheel and advance, so circulation is gone down, and then just drives front-wheel and ceaselessly travels forward.Because of this front-wheel drive is to be installed on front-wheel and the standpipe, do not change the foot-operated back-wheel drive part of former bicycle, so this bicycle can be realized manually, foot-propelled or trick and moving, reach desirable body-building effect.
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model construction profile scheme drawing;
Fig. 3 is the utility model handlebar, driving disk part-structure scheme drawing;
Fig. 4 is the utility model front-wheel flower-drum part-structure scheme drawing.
Among the figure: 1-handlebar, 2-transverse axis, 3-bearing, 4-driving disk, 5,5 '-left and right sides flywheel, 6-killer, 7,7 '-roller chain, 8,8 '-the driving rope, 9,9 '-time chain cable, 10-pulley, 11-front-wheel, 12 mudwinges, 13-flower-drum, 14-standpipe, 15-shell.
Embodiment: with reference to Fig. 1-4, fix a transverse axis (2) on bicycle profile tube (14) top, because this transverse axis (2) has two bearings (3) supporting shell (15), welding tractor is (1) in the middle part of shell (15), front end welding or riveted joint driving disk (4) are so this driving disk (4) can rotate with the rotation up and down of handlebar (1).Respectively load onto the flywheel (5.5 ') that a number of teeth equates simultaneously in front-wheel (11) flower-drum (13) both sides, article two, roller chain (7.7 ') is set on the left and right sides flywheel (5.5 '), this two roller chains (7.7 ') end connects driving rope (8.8 '), the other end connects back chain cable (9.9 '), and the upper end that drives rope (8.8 ') and time chain cable (9.9 ') is separately fixed at the both sides of driving disk (4).Like this, when people rotate handgrip (1) with hand, just can drive driving disk (4) and rotate, thereby rope (8.8 ') drive roller chain (7.7 ') moves and flywheel (5.5 ') rotates by driving, to realize manually driving the purpose of cycle racing.
For twice chain cables (9.9 ') about preventing, run into front-wheel (11) mudwing (12), the utility model is fixed with small sheave (10) at the mudwing (12) of bicycle front-wheel (11).
In order to control the angle that handlebar (1) rotates, the utility model is equipped with killer (6) simultaneously on the below standpipe (14) of bicycle handle bar (1), and this killer (6) can move up and down in standpipe (14), reaches the angle that control handlebar (1) rotates.
Claims (3)
1, wheel apparatus before a kind of bicycle handle bar drives has handlebar, standpipe, front-wheel, flower-drum, mudwing, it is characterized in that:
A, riser top ends directly are fixed with transverse axis, and this transverse axis is equipped with two cover bearings and is supporting shell, shell middle part welding tractor handle, welding of shell front end or riveted joint driving disk;
The flywheel that a number of teeth equates is respectively adorned in b, front-wheel flower-drum both sides;
Be set with roller chain on c, the flywheel, this roller chain one end connects and drives rope, and the other end connects back chain cable, drives rope and go back to the chain cable upper end to be separately fixed at the driving disk both sides about roller chain, driving rope, time chain cable are divided into two groups.
2, wheel apparatus before bicycle handle bar according to claim 1 drives is characterized in that fixing on the front wheel guard small sheave.
3, drive preceding wheel apparatus according to the described bicycle handle bar of claim 1.2, it is characterized in that there is a killer handlebar below, this killer is fixed on the standpipe.
