Abstract
The utility model relates to a double-drive bicycle which is formed by bicycle handles, a front wheel, a back wheel, a front fork, a back fork, a bicycle frame, a seat, pedals, a chain wheel, a first rotation shaft, a second rotation shaft and a third rotation shaft. The seat is arranged at the upper end of the bicycle frame, the chain wheel and the pedals are arranged at the lower end of the bicycle frame, the back fork and the back wheel are arranged at the left end of the bicycle frame, the front fork is arranged at the right end of the bicycle frame, and the first rotation shaft is arranged inside the bicycle frame. The bicycle handles are arranged at the upper end of the front fork, the front wheel is arranged at the lower end of the front fork, and the second rotation shaft and the third rotation shaft are arranged inside the front fork. According to the double-drive bicycle, the back wheel can be driven by the chain wheel to rotate, and the front wheel can be driven by the chain wheel to conduct driving. In addition, the double-drive bicycle is simple in structure, convenient to use and wide in application.
Description
Technical field
The utility model relates to a kind of bicycle, especially a kind of double-driving bicycle driven.
Background technology
Bicycle claims again bicycle or bicycle, normally the two small-sized land-going machines of taking turns.After the people rides car, take foot pedal as power, be the vehicle of environmental protection.The main part of present bicycle: comprise vehicle frame, front fork, handlebar, saddle and front fork spare etc.
Along with the development of society, various bicycles have all produced, such as multi-functional cross-country car, mountain-climbing cross-country car, road racing car, general scheduled bus, folding bicycle etc.Bicycle uses very extensive, on the present social price, the oil expense rises violently, use other vehicle need to spend many money, the city of some crowded traffic particularly, not only to spend money also in vain waste many times, if use in a large number bicycle, can alleviate the problem of crowded traffic exactly.Existing general scheduled bus, people are used for shopping, trip, on and off duty etc., closely link to each other with people's life.
If existing bicycle main rotates by foot pedal band movable chain wheel, chain wheel rotates by the chain-driving trailing wheel again, trailing wheel rotates rear so that bicycle can be walked, drive the bicycle bicycle that sometimes is easy to make that advances only according to trailing wheel and be absorbed in the somewhere, can not advance, advance and just can reduce bicycle and be absorbed in the somewhere if front-wheel also can drive bicycle.
The utility model content
In order to overcome the deficiency of above-mentioned existing bicycle, the purpose of this utility model is to provide a kind of double-driving bicycle driven, and it adopts and be provided with the first rotating shaft in vehicle frame, is provided with the second rotating shaft and the 3rd rotating shaft in the front fork.
In order to realize that the technical scheme that the purpose of this utility model adopts is: a kind of double-driving bicycle driven is characterized in that: it is made of handlebar, front-wheel, trailing wheel, front fork, back vent, vehicle frame, bench, pedal, chain wheel, the first rotating shaft, the second rotating shaft, the 3rd rotating shaft; The upper end of described vehicle frame is provided with bench, and the lower end is provided with chain wheel and pedal, and left end is provided with back vent and trailing wheel, and right-hand member is provided with front fork, and inside is provided with the first rotating shaft; The upper end of described front fork is provided with handlebar, and the lower end is provided with front-wheel, and inside is provided with the second rotating shaft and the 3rd rotating shaft.
The beneficial effects of the utility model are: it can drive trailing wheel by chain wheel and rotate, and can drive f-w-d by chain wheel again, and simple in structure, easy to use, widely applicable.

The specific embodiment
In Fig. 1, Fig. 2, Fig. 3, Fig. 4, the first embodiment shown in Figure 5, a kind of double-driving bicycle driven is characterized in that: it is made of handlebar, front-wheel, trailing wheel, front fork, back vent, vehicle frame, bench, pedal, chain wheel, the first rotating shaft, the second rotating shaft, the 3rd rotating shaft; The upper end of described vehicle frame is provided with bench, and the lower end is provided with chain wheel and pedal, and left end is provided with back vent and trailing wheel, and right-hand member is provided with front fork, and inside is provided with the first rotating shaft; The upper end of described front fork is provided with handlebar, and the lower end is provided with front-wheel, and inside is provided with the second rotating shaft and the 3rd rotating shaft.
In Fig. 1, the second embodiment shown in Figure 3, described support is used for front fork and back vent are connected, firm integral structure; Described trailing wheel is connected with back vent by rotating shaft, gives self by chain with the transmission of power of chain wheel; Described chain wheel is cylindric, is connected with support by rotating shaft, and the rear end is provided with finishing bevel gear cuter; Described pedal is connected with chain wheel by crank, is used for transmission of power with people's pedal to chain wheel; Described front-wheel is connected with the lower end of front fork with rotating shaft by unilateral bearing.
In Fig. 2, Fig. 4, the 3rd embodiment shown in Figure 5, described the first rotating shaft is cylindric, and top and bottom are provided with finishing bevel gear cuter, are connected with support by bearing; Described the second rotating shaft and the 3rd rotating shaft are cylindric, and top and bottom are provided with finishing bevel gear cuter, are connected with front fork by bearing; Described connecting rod is cylindric, top and bottom are provided with the upper end finishing bevel gear cuter, be connected with the upper end of the first rotating shaft by the gear engagement, and be connected with the upper end of the second rotating shaft with the 3rd rotating shaft, be used for the rotation of the first rotating shaft is passed to the second rotating shaft and the 3rd rotating shaft; Described the first rotating shaft, the second rotating shaft, the 3rd rotating shaft, connecting rod form a driving device, when chain wheel rotates, finishing bevel gear cuter by the chain wheel rear end passes to the first rotating shaft with rotation, by connecting rod the rotation of the first rotating shaft is passed to the second rotating shaft and the 3rd rotating shaft again, the second rotating shaft and the 3rd rotating shaft are rotated by the rotating shaft that the gear engagement drives between front-wheel and the front fork again, under the effect of unilateral bearing, so that front-wheel only can rotate in a direction.
When using the utility model, at first then people's seat steps on pedal with pin to bench, just can allow front-wheel and trailing wheel roll forward simultaneously, simple in structure, easy to use.
