The specific embodiment
Shown in accompanying drawing; A kind of double front wheel turning of bicycle of the present invention mechanism; Comprise handle 1, axle 2, preceding standpipe 3, two front-wheels 11, beam 4, rotating shaft 5, rotating shaft pipe 6, front wheel spindle 7, reset lever 81, tension spring 82, hangers 83, connecting rod 9, side arm bar 10 etc. before also comprising; Handle 1 is captiveed joint with an axle 2, and in the standpipe 3, preceding standpipe 3 is welded to connect with front vehicle frame before being installed on axle 2; Preceding standpipe 3 a middle and lower parts side of front vehicle frame 12 dorsad are provided with preceding beam 4; One end and preceding standpipe 3 middle and lower parts of preceding beam 4 are welded to connect, and the other end of preceding beam 4 and rotating shaft pipe 6 are welded to connect, and rotating shaft 5 is installed in the rotating shaft pipe 6; Rotating shaft 5 turns forward; Formation is the leaning angle a of rotating shaft 5 with the angle of vertical line, and rotating shaft 5 lower ends and front wheel spindle 7 middle parts are welded to connect, and a front-wheel 11 is respectively installed at the both ends of front wheel spindle 7; Front wheel spindle 7 middle parts are welded to connect with a end perpendicular to the reset lever 81 of front wheel spindle 7; The other end towards the reset lever 81 of preceding standpipe 3 lower ends then is provided with connecting bore; Be welded with hangers 83 to axle front side, 2 lower end; Hangers 83 is provided with the hangers hole, and an end of tension spring 82 is through passing the hangers hole and being connected axle 2 lower ends, and the other end of tension spring 82 is connected with the connecting bore of reset lever 81; Be welded to connect left side, axle 2 lower ends with an end that is parallel to the side arm bar 10 of front wheel spindle 7; The other end of side arm bar 10 is provided with connecting bore; With the convexity that is set with the band connecting bore on the front wheel spindle 7 of side arm bar 10 homonymies; This front wheel spindle 7 raisings to distance of welding the reset lever place is identical with side arm bar 10 length, and all there is connecting bore at connecting rod 9 two ends, and the connecting bore of connecting bore through bolt and side arm bar 10 and front wheel spindle 7 raisings is hinged respectively; Identical the distance in the middle of axle 2 lower ends to the front wheel spindle 7 with the length of connecting rod 9.
The leaning angle a of rotating shaft 5 be 15 the degree to 25 the degree, can be 15 the degree, 17.5 the degree, 20 the degree, 25 the degree etc.
The principle of work of double front wheel turning of bicycle mechanism is; When handle 1 clickwise; The side arm bar 10 of axle on 2 clickwise thereupon; Drive rotating shaft 5 clickwises through connecting rod 9 and front wheel spindle 7, make rotating shaft pipe 6 drive preceding beam 4, preceding standpipe 3, front vehicle frame 12 and whole vehicle frame and also tilt to the right thereupon because rotating shaft 5 has leaning angle this moment.Otherwise when handle 1 left-hand revolution, beam 4, preceding standpipe 3, front vehicle frame 12 and whole vehicle frame also tilted thereupon to the left before rotating shaft pipe 6 drove.
The effect of tension spring 82 is to make the bicycle steering hardware have auto-reset function.The pulling force of tension spring 82 does not deflect reset lever 81, thereby steering hardware can automatically reset, to keep bicycle to overtake.
Hence one can see that; Use the double front wheel bicycle of double front wheel turning of bicycle of the present invention mechanism, when under having the certain speed situation that particularly high speed is ridden, turning, because the effect of steering hardware; Bicycle bevelled direction and centnifugal force direction are antithesis; Thereby the centripetal force that produces has been eliminated action of centrifugal force, makes bicycle be difficult for tumbling, and has ensured the safety when people by bike.
This double front wheel turning of bicycle mechanism is widely used, and can not only be applied to bicycle, can also be applied to Electrical Bicycle or motor bike, and various child's bicycles etc.
