Abstract
The utility model relates to a bicycle, in particular to a hand and foot dual driving and double-chain bicycle. The hand and foot dual driving and double-chain bicycle structurally comprises a bicycle frame, a four-axis driving box mechanism is arranged on the bicycle frame, the upper portion of the four-axis driving box mechanism is connected with a handlebar through a rocker, the lower portion of the four-axis driving box mechanism is connected with a small chain wheel of a pedal coaxial chain wheel on the bicycle frame through a hand-operated driving chain, a large chain wheel of the pedal coaxial chain wheel is connected with a back wheel rotating shaft through a chain, and the pedal coaxial chain wheel is connected with pedals. According to the hand and foot dual driving and double-chain bicycle, the production cost of the driving box mechanism is reduced, and the structure is more reasonable.
Description
Technical field
The utility model relates to a kind of bicycle, particularly the two chain bicycles that drive of a kind of trick.
Background technology
Bicycle under prior art is all generally to rely on foot to pedal to provide power, and also having some disabled person's bicycles is the simple hand power that obtains that relies on, and its power supply mode is all more single.
The patent of invention double-driving bicycle driven by hand and foot that notification number is CN102180223A provides a kind of can obtain the bicycle of power simultaneously by manual and pedal, it not only can be tempered upper limbs force but also the speed of a motor vehicle can be provided.But this bicycle, its power driven case apparatus design comparison is complicated, and whole transmission adopts one whole chain, once damage, needs whole replacing, not only causes car load cannot continue to ride, and also corresponding raising of productive costs.
Summary of the invention
In order to solve the problem of prior art, the utility model provides a kind of trick two chain bicycles that drive, and it has reduced the productive costs of driving box mechanism, and structure is more reasonable.
The technical scheme that the utility model adopts is as follows:
The two chain bicycles that drive of a kind of trick, comprise vehicle frame, on vehicle frame, be provided with Si Zhou driving box mechanism, described Si Zhou driving box mechanism top connects handlebar by handlebar rocking bar, below is by the minor sprocket of the foot-operated coaxial sprocket on manual drives chain interlock vehicle frame, wheel shaft after hinge wheel on described foot-operated coaxial sprocket links by chain, described foot-operated coaxial sprocket interlock stretcher.
Si Zhou driving box mechanism comprises housing, in described housing, be hinged with the handlebar axis that connects handlebar rocking bar, on described handlebar axis, interlock has fan-shaped driving wheel, described fan-shaped driving wheel meshes with the miniature gears of the first coaxial flower wheel, on the main shaft of the described first coaxial flower wheel, be also provided with middle gear and the big gear wheel with power-transfer clutch, described middle gear and reversing gear engagement, described big gear wheel meshes with the big gear wheel of the second coaxial flower wheel, the miniature gears of the second described coaxial flower wheel also meshes with described reversing gear, the described manual drives chain of main shaft interlock of the second described coaxial flower wheel.
Technical scheme band Song's that the utility model provides beneficial effect is:
Pass through structural development, change original single chain into two chain gears, an once damage, do not affect and continue to ride, and by the optimal design to driving box, reduced by a power wheel, thereby reduced productive costs, and realize than fast adjusting by the gear ratio of foot-operated coaxial sprocket, thereby do not affect the fast problem changing of ratio of bringing because reducing power wheel.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the two integral structure schematic diagrams that drive chain bicycle of a kind of trick of the present utility model;
Fig. 2 is the two structural front view that drive four axle driving box of chain bicycle of a kind of trick of the present utility model;
Fig. 3 is the two structure left views that drive four axle driving box of chain bicycle of a kind of trick of the present utility model.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
Embodiment mono-
As shown in Figure 1, the two chain bicycles that drive of a kind of trick, comprise vehicle frame 1, on vehicle frame 1, be provided with Si Zhou driving box mechanism 2, described Si Zhou driving box mechanism 2 tops connect handlebar 4 by handlebar rocking bar 3, below is by the minor sprocket of the foot-operated coaxial sprocket 6 on manual drives chain 5 interlock vehicle frames 1, the hinge wheel on described foot-operated coaxial sprocket 6 by chain 7 interlocks after wheel shaft 8, described foot-operated coaxial sprocket 6 interlock stretchers 9.
As accompanying drawing 2, shown in 3, four axle driving box 2 mechanisms comprise housing 21, in described housing 21, be hinged with the handlebar axis 22 that connects handlebar rocking bar 3, on described handlebar axis 22, interlock has fan-shaped driving wheel 23, described fan-shaped driving wheel 23 and 24 engagements of the miniature gears of the first coaxial flower wheel, on the main shaft of the described first coaxial flower wheel, be also provided with middle gear 25 and big gear wheel 26 with power-transfer clutch, described middle gear 25 and reversing gear 27 engagements, described big gear wheel 26 and 28 engagements of the big gear wheel of the second coaxial flower wheel, the miniature gears 29 of the second described coaxial flower wheel also meshes with described reversing gear 27, the described manual drives chain 5 of main shaft interlock of the second described coaxial flower wheel.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
