Abstract
The utility model discloses a gear wheel driven bicycle, which comprises a vehicle body, a middle shaft and a gear wheel mechanism which is connected on the vehicle body; and the gear wheel driven bicycle is characterized in that: the gear wheel mechanism includes a driving wheel and a driven wheel, the driving wheel is connected on the middle shaft of the vehicle body, the ratio of the driving wheel teeth number to the driven wheel teeth number is bigger than 1, the driven wheel is the step wheel, a small wheel is the gear wheel, and a big wheel is the chain wheel. The gear wheel driven bicycle has the advantages that the manufacture cost is low, the bicycle is durable, the transmission distance of the chain wheel is shortened, the straightness can be ensured in the process of transmission, the chain can not fall easily, and the bicycle has more advantages than traditional single chain wheel transmission.
Description
Technical field
The utility model relates to bicycle and drives the field.
Background technology
Existing bicycle drives and mostly is chain drive, and normally driving wheel drives flower wheel by chain, and this structure has had above century-old history so far because simplicity of design, practical is followed bicycle.Even the exploitation of new bicycle now, design engineer is also still habitually continued to use this kind structure, seldom makes an amendment.But this kind driving exists bigger defective when design is used, driving wheel can not design excessive, the flower wheel design can not be too small, because the restriction of chain gear load, driving gear can not be too small, and this just makes under same material and treatment process, the design space of transmitting ratio is comparatively narrow and small, can only be designed to conventional ratio, be difficult to satisfy various crowds' needs, particularly Zhuan Ye racing car personnel.
Summary of the invention
The deficiency that the utility model exists on design is used in view of prior art, the spy provides a kind of new gear to drive bicycle.
The technical scheme that the utility model solves existing issue is: a kind of gear drive bicycle, comprise car body, axis and be connected in gear mechanism on the car body, it is characterized in that: gear mechanism comprises driving wheel and flower wheel, driving wheel is connected on the axis of car body, driving wheel and flower wheel ratio of number of teeth are greater than 1, flower wheel is a stepped wheel, and steamboat is a gear, and bull wheel is a sprocket wheel.
Gear drive bicycle described in the utility model is characterized in that: driving wheel is an inner gear.
Gear drive bicycle described in the utility model is characterized in that: driving wheel is an external gear.
The utility model compared with prior art, its beneficial effect is that driving wheel is become gear by original sprocket design, under same material and treatment process, allow transmitting ratio that bigger space has been arranged in design, can satisfy multiple crowd's demand, the utility model is cheap, durable in use, shortened the transmission distance of sprocket wheel, guaranteed the straightness accuracy in the transmission process, be difficult for falling chain, have more advantage than traditional single chain sprocket drive.

The specific embodiment
Referring to Fig. 1-2, the implementation case comprises: a kind of gear drive bicycle, comprise car body, axis 6 and be connected in gear mechanism on the car body, it is characterized in that: gear mechanism comprises driving wheel 1 and flower wheel 2, driving wheel 1 is connected on the axis 6 of car body, and driving wheel 1 and flower wheel 2 ratios of number of teeth are greater than 1, and flower wheel 2 is a stepped wheel, steamboat 3 is a gear, and bull wheel 4 is a sprocket wheel.
Referring to Fig. 3-4, driving wheel 1 is an external gear in the implementation case, and reverse wheels 5 are set in the middle of external gear and the flower wheel 2, like this flower wheel 2 just can with driving wheel 1 in the same way, the minor sprocket of flower wheel 2 drive back wheels of vehicle.Driving wheel 1 can be according to different crowds' needs design with the transmitting ratio of back wheels of vehicle minor sprocket during use.
Claims (3)
1, a kind of gear drive bicycle, comprise car body, axis and be connected in gear mechanism on the car body, it is characterized in that: gear mechanism comprises driving wheel and flower wheel, driving wheel is connected on the axis of car body, driving wheel and flower wheel ratio of number of teeth are greater than 1, flower wheel is a stepped wheel, and steamboat is a gear, and bull wheel is a sprocket wheel.
