Abstract
The utility model relates to a high-speed bicycle. The utility model is mainly characterized in that an acceleration big and a small rotary tables are installed on a bicycle frame, a starting rotary table is installed on the left side of a center shaft, a guide rotary table is installed on the right side of the center shaft, the number of teeth of the acceleration small rotary table is two thirds of that of the starting rotary table, the number of teeth of the big rotary table is no less than that of the starting rotary table, and chain transmission is respectively formed between the starting rotary table and the acceleration small rotary table, the acceleration big rotary table and a left tooth table of the guide rotary table and a right tooth table of the guide rotary table and a fly wheel. The utility model has the advantages of simple structure and low cost, and the speed of the utility model can be over 50 percent faster than that of an ordinary bicycle; the utility model is especially suitable for rural towns and backcountry districts to use.
Description
The utility model relates to a kind of bicycle.
The bicycle of prior art is restricted and strengthen the starting wheel disc number of teeth because the starting wheel disc directly drives flywheel, and transmitting ratio is less, and gait of march is slow.Though existing in addition variable speed bicycle can improve speed, complex structure, bad easily and bring a high price, be unsuitable for vast rural area and backcountry and use.
The purpose of this utility model provides a kind of simple in structure, speed and improves more than 50% quick bicycle with low cost, durable than existing bicycle.
The purpose of this utility model is achieved in that it comprises front and back wheel, handlebar, car fork, vehicle seat and vehicle frame, it is characterized in that: starting wheel disc, guide wheel disk are installed on the left and right sides of vehicle frame sleeve pipe respectively, the starting wheel disc is captiveed joint with axis, and guide wheel disk and axis are by the movable assembling of bearing; Activity is assemblied in and accelerates on the wheel shaft after accelerating small trochal disc and accelerate big trochal disc to be fixed together, and accelerates wheel shaft and is fixed on the vehicle frame by axle stand; The number of teeth of accelerating small trochal disc is the starting wheel disc number of teeth
The number of teeth of accelerating big trochal disc is no less than the number of teeth of starting wheel disc, the starting chain is engaged on the starting wheel disc and accelerates on the small trochal disc, central links is engaged on the left fluted disc of accelerating big trochal disc and guide wheel disk, the flywheel chain is engaged on the right fluted disc and flywheel of guide wheel disk, all is coated with chain cover on each wheel disc and the chain.
The purpose of this utility model can also following manner realize: the number of teeth that the number of teeth of quickening big trochal disc equals to start wheel disc.
The utlity model has simple in structurely, with low cost, the comparable existing bicycle of speed is fast more than 50%, is particularly suitable for the advantage that rural urbanization uses.
Elaborate below in conjunction with accompanying drawing:
Fig. 1 the utility model structural representation
Fig. 2 driving wheel disc portion section-drawing
Fig. 3 accelerates the wheel disc fragmentary cross-sectional view
The utility model structurally mainly is to have increased the quickening wheel disc than prior art bicycle, and the guide wheel disk part improves rotating speed by one little one fast greatly wheel disc.Guide wheel disk 5 is the combination of the fluted disc of two identical numbers of teeth, and it only rises with fast transfer function, and neither speedup is not slowed down yet.Owing to accelerate the small trochal disc number of teeth is to start wheel disc 2
, and it is identical with the number of teeth of starting wheel disc 2 to accelerate big trochal disc 10 numbers of teeth, so starting wheel disc 2 turns around, accelerates small trochal disc to turn around half; Again owing to accelerate big trochal disc and be fixed together,, be delivered to rotating speed on the flywheel 15 just than ordinary bicycle fast 50% through guide wheel disk 5 like this so also turn around half with accelerating small trochal disc.
The driving wheel disc portion: starting wheel disc 2, guide wheel disk 5 are installed on the left and right sides of vehicle frame sleeve pipe 3 respectively, the two is that left foot pedals 1 and right pedal 7 again toward outside, the starting wheel disc is fixed on the axis 4, and guide wheel disk 5 assembles by bearing 6 activities with axis 4, can freely rotate on axis.
Quickening wheel disc portion: activity is assemblied in and accelerates on the wheel shaft 11 after accelerating small trochal disc 9 and accelerate big trochal disc 10 to be fixed together, and accelerates wheel shaft 11 and is fixed on the axle stand 12, and axle stand is fastened on the last underbeam of vehicle frame 16 at two ends about in the of 12.Starting chain 8 is engaged on starting wheel disc 2 and accelerates on the small trochal disc 9, and central links 13 is engaged on the left fluted disc of accelerating big trochal disc 10 and guide wheel disk 5, and flywheel chain 14 is engaged on the right fluted disc and flywheel 15 of guide wheel disk 5.All be coated with chain cover on each wheel disc and the chain.
Claims (2)
1, a kind of quick bicycle, comprise front and back wheel, handlebar, car fork, vehicle seat and vehicle frame (16), it is characterized in that: starting wheel disc (2), guide wheel disk (5) are installed on the left and right sides of vehicle frame sleeve pipe (3) respectively, the starting wheel disc is captiveed joint with axis (4), and guide wheel disk (5) assembles by bearing (6) is movable with axis (4); Activity is assemblied in and accelerates on the wheel shaft (11) after accelerating small trochal disc (9) and accelerate big trochal disc (10) to be fixed together, and accelerates wheel shaft (11) and is fixed on the vehicle frame (16) by axle stand (12); The number of teeth of accelerating small trochal disc is the starting wheel disc number of teeth
The number of teeth of accelerating big trochal disc is no less than the number of teeth of starting wheel disc, starting chain (8) is engaged on starting wheel disc (2) and accelerates on the small trochal disc (9), central links (13) is engaged on the left fluted disc of accelerating big trochal disc (10) and guide wheel disk (5), flywheel chain (14) is engaged on the right fluted disc and flywheel (15) of guide wheel disk (5), all is coated with chain cover on each wheel disc and the chain.
2, quick bicycle according to claim 1, tool is characterised in that: the number of teeth of accelerating big trochal disc (10) equals to start the number of teeth of wheel disc (2).
